      Author(s): Ala Al-Lawati, Anson Cheung

      Teaser Mitral valve disease prevalence is on the rise worldwide, affecting an estimated 2% of the general population. Novel transcatheter mitral valve replacement technologies are being developed and may provide a viable and safe option in patients who are deemed otherwise not suitable candidates for conventional mitral valve surgery. This article reviews these devices and describes trials of first in-human use.

  • Transcatheter Mitral Valve-in-Valve Therapy
    • Abstract: Publication date: January 2016

      Author(s): Jose F. Condado, Brian Kaebnick, Vasilis Babaliaros

      Teaser Valve-in-valve and valve-in-ring transcatheter mitral valve replacement can be used in for the treatment of inoperable patients with failing mitral surgical bioprosthesis or valve repairs. Preprocedural multi-image evaluation by a heart team must include transthoracic echocardiogram, transesophageal echocardiogram, and cardiac computed tomography angiography (CTA). CTA is used to determine access site (transapical, transseptal, or transatrial), transcatheter valve size, and landing zone. Though complications can occur (ie, valve embolization, bleeding, or vascular complications), this less invasive procedure has a reported success rate of 70% to 100% and is now increasingly used.

  • MitraClip Therapy for Mitral Regurgitation
    • Abstract: Publication date: January 2016
      Source:Interventional Cardiology Clinics, Volume 5, Issue 1
      Author(s): Ted Feldman, Arjun Mehta, Mayra Guerrero, Justin P. Levisay, Michael H. Salinger

      Teaser Therapy for mitral regurgitation (MR) has been synonymous with mitral valve surgery. Operative approaches for degenerative MR repair have been associated with excellent results, with durable long term outcomes. Surgery for functional MR has been less successful. MitraClip has shown promise for functional MR, especiall in patinets who are high risk for surgery. The aggregate of nonrandomized global experience with MitraClip in functional MR has been consistent in showing improvements in symptoms and left ventricular remodeling. It remains to be seen how MitraClip therapy will compare with best medical therapy. The COAPT trial will clarify this question.

  • Targeted Transseptal Access for MitraClip Percutaneous Mitral Valve Repair
    • Abstract: Publication date: January 2016

      Author(s): Gagan D. Singh, Thomas W. Smith, Jason H. Rogers

      Teaser Targeted transseptal puncture remains the most critical initial part of the overall MitraClip procedure. Care and attention must be implemented for patient safety in choosing the optimal puncture site. A consistent and step-by-step methodical approach is recommended. As experienced operators are targeting more complex and nontraditional pathologic conditions, use of adjunctive tools and maneuvers (outlined in this review) are paramount to achieving successful targeted transseptal access and ultimately procedural success.

      Author(s): Paul Sorajja

      Teaser For patients with paravalvular mitral prosthetic regurgitation, percutaneous repair is an established therapy for the treatment of symptoms of heart failure or hemolytic anemia. Percutaneous repair of paravalvular mitral regurgitation is a complex procedure with unique technical challenges, even when performed in experienced centers. Herein, the author discusses patient selection, catheter-based techniques for repair, and clinical outcomes of percutaneous repair for paravalvular mitral regurgitation.

      Author(s): Elizabeth M. Perpetua, Dmitry B. Levin, Mark Reisman

      Teaser Transcatheter mitral valve therapy requires an in-depth understanding of the mitral valve apparatus (annulus, leaflets, chordae tendinae, and papillary muscles) and the impact of various disease states. Adjacent structures (left atrium, left ventricular outflow tract, aortic valve, coronary sinus, and circumflex artery) must also be respected. This article reviews the anatomy and function of the normal and diseased mitral valve apparatus and the implications for catheter-based intervention.

  • Echocardiographic Imaging of the Mitral Valve for Transcatheter
           Edge-to-Edge Repair
    • Abstract: Publication date: January 2016

      Author(s): Jeffrey M. Paulsen, Thomas W. Smith

      Teaser Echocardiography continues to be the most effective imaging tool for the diagnosis and follow-up of mitral valve disease. This review addresses the use of transthoracic echocardiography and transesophageal echocardiography in the planning and guidance of transcatheter mitral valve therapies. Many of the echo-imaging guidance techniques are applicable to transcatheter intervention as a whole. However, given that the MitraClip is the only device approved for mitral regurgitation at present, specific attention is paid to this procedure, with additional focus on the guidance of noncentral repair. The imaging techniques discussed will be applicable to future devices.

  • MitraClip Therapy for Mitral Regurgitation
    • Abstract: Publication date: Available online 9 October 2015

      Author(s): G. Athappan, Mohammad Qasim Raza, Samir R. Kapadia

      Teaser Primary mitral regurgitation (MR) owing to degenerative changes in the structural components of the mitral valve is a common acquired valvular pathology in the elderly. Surgical correction with mitral valve repair (MVRe) or replacement (MVR) is the mainstay of therapy. A significant proportion of patients are ineligible for MVRe/MVR owing to prohibitive surgical risk from advanced age, poor ventricular function, or associated comorbidities. Percutaneous mitral valve repair techniques have been developed to fill this void. The edge-to-edge MitraClip has accrued the largest human experience. This paper reviews the available literature on the MitraClip device for treatment of primary MR.

      Author(s): Vladimir Jelnin, Chad Kliger, Fabio Zucchetta, Carlos E. Ruiz

      Teaser With increasing utilization of cardiac computed tomographic angiography (CTA) and widespread adoption of fusion imaging technology allowing the merger of pre-procedural CTA with fluoroscopy, the ability of CTA to guide structural heart interventions has evolved significantly. It has opened new possibilities in mitral valve (MV) interventions with improved pre-procedural planning and intra-procedural guidance. Given the lack of fluoroscopic landmarks of the mitral apparatus and continued growth of native MV device technologies, the value of CTA will continue to develop. The goal of this chapter is to detail the role of CTA in MV imaging and support for transcatheter therapies.

  • Coronary Sinus-Based Approach to Mitral Regurgitation
    • Abstract: Publication date: Available online 6 October 2015
      Source:Interventional Cardiology Clinics
      Author(s): Steven L. Goldberg, Christoph Hammerstingl

      Teaser Functional, or secondary, mitral regurgitation (FMR) is clinically important because patient with congestive heart failure with FMR have worse clinical outcomes and associated higher risks than patients without FMR. There is interest in finding repair techniques which may modify the mitral valve dysfunction and reduce the clinical impact. Although several devices have taken advantage of the close anatomical relationship between the coronary sinus and the posterior annulus of the mitral valve, in order to provide a cinching force on the mitral annulus, only the Carillon device is currently in use in humans. A double blind randomized trial is currently being done to evaluate the value of this therapy, building upon the favorable result of three prior safety and efficacy trials, which have led to European approval of the device.

  • Fractional Flow Reserve for the Evaluation of Tandem and Bifurcation
           Lesions, Left Main, and Acute Coronary Syndromes
    • Abstract: Publication date: October 2015

      Author(s): Jaya Mallidi, Amir Lotfi

      Teaser Fractional flow reserve (FFR) is a well-established invasive tool to assess the physiologic significance of a coronary stenosis. Several randomized trials proved the safety of deferring revascularization based on FFR in subjects with stable coronary artery disease with single or multivessel disease. Subjects with tandem or bifurcations lesions, left main disease, and acute coronary syndromes were not included in these trials. Unique hemodynamic changes occur in each of these situations, making the measurement and interpretation of FFR challenging. This article reviews the technical aspects of assessing FFR and literature supporting FFR-guided revascularization in each of these situations.

      Author(s): Ibrahim Danad, Lohendran Baskaran, James K. Min

      Teaser Fractional flow reserve derived from coronary computed tomography angiography (FFRCT) has emerged as a powerful tool for the assessment of flow-limiting coronary stenoses. To date, FFRCT is the only noninvasive imaging modality for the depiction of lesion-specific ischemia and large prospective multicenter studies have established its high diagnostic value. The nature of FFRCT allows the prediction of functional outcome of coronary stenting, which will expand the role of cardiac computed tomography in the evaluation and management of coronary artery disease.

  • Association of Wall Shear Stress with Coronary Plaque Progression and
           Transformation
    • Abstract: Publication date: October 2015
      Source:Interventional Cardiology Clinics, Volume 4, Issue 4
      Author(s): Olivia Y. Hung, Adam J. Brown, Sung Gyun Ahn, Alessandro Veneziani, Don P. Giddens, Habib Samady

      Teaser Coronary endothelial function regulation by wall shear stress (WSS), the frictional force of blood exerted against the vessel wall, can help explain the focal propensity of plaque development in an environment of systemic atherosclerosis risk factors. Sustained abnormal pathologic WSS leads to a proatherogenic endothelial cell phenotype, plaque progression and transformation, and adaptive vascular remodeling in site-specific areas. Assessing dynamic coronary plaque compositional changes in vivo remains challenging; however, recent advances in intravascular image acquisition and processing may provide swifter WSS calculations and make possible larger prospective investigations on the prognostic value of WSS in patients with coronary atherosclerosis.

      Author(s): Arnold H. Seto, David Tehrani, Morton J. Kern

      Teaser Coronary hemodynamic measurements provide a critical tool to assess the ischemic potential of coronary stenoses. Fractional flow reserve (FFR) is a reliable method to relate translesional coronary pressures to hyperemic myocardial blood flow. Although a basic understanding in FFR can be quickly achieved, many of the nuances and potential pitfalls require special attention. The authors discuss the practical setup of coronary pressure measurement, the most common pitfalls in technique and ways to avoid them, and the limitations of available pharmacologic hyperemic methods.

      Teaser Fractional flow reserve (FFR) has become widely used for physiologic assessment of intermediate coronary lesions. The Fractional Flow Reserve to Determine Appropriateness of Angioplasty in Moderate Coronary Stenoses (DEFER) trial established the safety of deferring angioplasty for moderate lesions that are not functionally significant. DEFER and Fractional Flow Reserve versus Angiography for Multivessel Evaluation 1 trials established the feasibility of FFR-guided intervention in stable and unstable patients with moderate coronary lesions, translating to improved clinical outcome and reduced number of unnecessary stents. This article reviews the trials establishing FFR as an important tool for on-the-table functional assessment of coronary lesions.

      Teaser Although coronary microcirculatory dysfunction occurs in numerous cardiac conditions and influences prognosis, it has been largely ignored in clinical practice due to the lack of adequate methods for its assessment. Microcirculatory dysfuntion may result from a variety of causes, including structural remodelling (arterioles or capillaries), dysregulation (paradoxical arteriolar vasoconstriction), hypersensitivity to vasoactive factors or adrenergic drive, and extravascular compression of collapsable elements. Thus, the selection of a method to interrogate coronary microcirculation should be based on the suspected cause of dysfunction. This article reviews such assessment tools and their prognostic information.

      Teaser We discuss the historical development of clinical coronary physiology, emphasizing coronary flow reserve (CFR) and fractional flow reserve (FFR). Our analysis focuses on the clinical motivations and technologic advances that prompted and enabled the application of physiology for patient diagnosis. CFR grew from the general concepts of physiologic and coronary reserve, linking the anatomic severity of a lesion to its impact on hyperemic flow. FFR developed from existing models relating pressure measurements to the potential for flow to increase after removing a stenosis. Because pressure measurements have proved easier and more robust than flow measurements, FFR has become the dominant metric.

  • The Concept of Functional Percutaneous Coronary Intervention

      Teaser The gold standard for assessing the severity of coronary stenoses has been coronary angiography. However, multicenter randomized clinical trials have demonstrated that treatment decisions based on angiography alone do not guarantee benefit to patients. Fractional flow reserve provides physiologic lesion assessment of coronary stenoses. The use of physiology improves clinical outcomes when used for decision making for coronary revascularization. In the era of increased scrutiny of appropriateness of cardiac catheterization and percutaneous coronary intervention, the use of physiologic assessment of the severity of coronary stenoses should be considered an integral adjunct to the anatomic evaluation provided by the coronary angiogram.

      Teaser Intravascular ultrasound (IVUS) has provided valuable information on cross-sectional coronary vascular structure and has played a key role in contemporary stent-based percutaneous coronary interventions (PCI). It accurately assesses coronary anatomy, assists in the selection of treatment strategy, and helps to optimize stenting outcomes. IVUS-guided PCI for drug-eluting stent implantation seems to be associated with a significantly reduced risk of death, myocardial infarction, target lesion revascularization, and stent thrombosis.

      Author(s): Jose M. De la Torre Hernandez , Tamara Garcia Camarero

      Teaser Limitations of angiography for assessment of coronary artery disease are well-known, but are more evident and relevant in the left main coronary artery (LMCA) segment given the amount of myocardium this vessel subtends and the risks associated with the presence of atherosclerosis and subsequent intervention. Intravascular ultrasound (IVUS) characterizes the severity of luminal narrowing, plaque morphology, and plaque extension into the distal bifurcation. Once the indication for percutaneous intervention (PCI) is established, information provided by IVUS is crucial to plan treatment and optimize results. IVUS-guided PCI with drug-eluting stents improves clinical outcomes, particularly in patients with distal left main disease.

      Teaser The analysis of bioresorbable scaffolds (BRSs) by optical coherence tomography (OCT) requires a dedicated methodology, as the polymeric scaffold has a distinct appearance and undergoes dynamic structural changes with time. The high resolution of OCT allows for the detailed assessment of scaffold implantation, rupture, discontinuity, and strut integration. OCT does not provide reliable information on the extent of scaffold degradation, as it cannot differentiate between polylactide polymer and the provisional matrix of proteoglycan formed by connective tissue. Three-dimensional OCT reconstruction can aid in the evaluation of BRS in special scenarios such as overlapping scaffold segments and bifurcations.

      Teaser Intravascular optical coherence tomography (OCT) is capable of acquiring 3-dimensional (3D) data of coronary arteries allowing for the assessment of plaques, stents, thrombus, side branches, and other relevant structures in a 3D fashion. Given that state-of-the-art OCT systems acquire images at a very high frame rate (up to 200 frames per second), typically a very large number of images per pullback (ie, 500 or more) need to be analyzed. The manual assessment of stents, plaques, and other structures is time-consuming, cumbersome, and inefficient and thus not suitable for on-line analysis during percutaneous coronary intervention procedures.

      Teaser Optical coherence tomography (OCT), which provides high-resolution imaging of the coronary vasculature, has provided novel insights into the pathophysiology of neointimal growth after drug-eluting stent (DES) implantation. The natural history, time course, and characteristics of strut coverage with neointima have been well defined by OCT. Pathology studies have identified strut coverage as a risk factor for stent thrombosis, and OCT studies have shown that next-generation DES have better strut coverage than first-generation DES. By reducing the incidence of stent thrombosis, improved strut coverage should lead to favorable clinical safety and the feasibility of shorter-duration dual antiplatelet therapy after DES implantation.

      Teaser Spontaneous coronary artery dissection (SCAD) is an infrequent condition that has been underdiagnosed and misdiagnosed. The use of intracoronary imaging with intravascular ultrasound or optical coherence tomography enables the accurate diagnosis of this challenging condition. Diagnostic and management algorithms have been proposed to improve the diagnosis and therapeutic stratification of SCAD. Optical coherence tomography has superior spatial resolution than intravascular ultrasound, and is instrumental in the diagnosis of SCAD cases where angiographic findings are ambiguous for confirming SCAD. Understanding the role and appropriate and careful use of this technology is expected to improve the diagnosis of SCAD, and also improve outcomes with percutaneous coronary intervention, when clinically indicated.

      Teaser Coronary angiography confirms or excludes coronary artery disease, assesses lesions severity, and helps to decide percutaneous coronary interventions (PCI). Coronary angiography has clear limitations. Intravascular imaging guides PCI. Frequency domain optical coherence tomography (OCT) gained attention for accurate planning and guidance of complex PCI. High-speed OCT image acquisition enables prompt vessel assessment in stable and unstable patients. The high-resolution images provide precise tissue characterization and a reliable quantitative assessment of the coronary pathology. Immediately after stent implantation, OCT allows accurate evaluation of stent expansion and symmetry. Real-time angio-OCT co-registration integrates OCT into the PCI workflow for accurate decision making.

      Teaser Optical coherence tomography evaluation of poststent results includes stent expansion as the absolute minimum stent area ratio by comparing the minimum stent area with the proximal and distal reference lumen areas or mean stent area defined as the total stent volume divided by the analyzed stent length; stent strut malapposition defined when the distance from the center of the blooming artifact and the surface of plaque is greater than the sum of stent thickness and polymer thickness; tissue protrusion through the stent struts; semiquantitative residual thrombus evaluation; and stent edge dissection.

      Teaser Stent thrombosis (ST) is a rare complication of percutaneous coronary interventions (PCI), especially with drug-eluting stents. ST presents as acute myocardial infarction requiring emergent repeat PCI; optimal reperfusion occurs in two-thirds of patients. As a result, ST has been associated with a high mortality rate and a high rate of recurrent thrombosis. We discuss the use of optical coherence tomography (OCT) for the diagnosis and evaluation of ST. OCT-guided ST management seems a feasible, safe, and appropriate approach. Intracoronary assesses the efficacy of coronary thrombus removal procedures and detects the prevalent stent-related factor that caused ST.

      Teaser Optical coherence tomography (OCT) is an intravascular imaging modality that enables high-resolution cross-sectional imaging of coronary arteries in vivo. With resolution that is a 10-fold improvement compared with intravascular ultrasonography, OCT can facilitate detailed plaque characterization. This article introduces the basic principles of OCT image acquisition and interpretation. Qualitative analysis entails the evaluation of plaque morphology, including features associated with plaque vulnerability to rupture. Quantitative analysis and recognition of OCT image artifacts are also discussed.

      Teaser Optical coherence tomography (OCT) is an intravascular imaging technology analogous to intravascular ultrasound, using near-infrared light rather than ultrasound, thereby providing higher-resolution images. This review provides a practical guide to OCT imaging, with a particular emphasis on the techniques and approaches to optimize image acquisition, improve the evaluation of coronary lesions, and guide the strategies for percutaneous coronary intervention.
