OBJECTIVES: Transcatheter approaches in heart valve disease became tremendously important and are currently established in the aortic position, but transcatheter tricuspid repair is still in its beginning and remains challenging. Replicating the surgical edge-to-edge technique, for example, with the MitraClip System (Abbott Vascular, Santa Clara, Calif), represents a promising option and has been reported successfully in small numbers of cases. However, up to now, few data considering the edge-to-edge technique as a transcatheter approach are available...

OBJECTIVES: During mitral valve repair using the foldoplasty technique, correct judgement of the necessary dimensions and orientation of the leaflet fold is a critical but challenging step that can affect the chances of successful repair. In this study, we investigated whether a leaflet plication clip can be used to guide suture foldoplasty for posterior leaflet prolapse of the mitral valve. METHODS: Complete posterior leaflet prolapse was created in both in vivo and ex vivo pig hearts by severing the chordae supporting the middle scallop...

This report describes a case of nonbacterial thrombotic endocarditis caused by Waldenström macroglobulinemia, with diffuse endocardial lesions and involvement of all 4 cardiac valves. A 77-year-old man presented with heart failure due to severe regurgitation of all 4 cardiac valves; surgical repair using bioprosthetic valves was indicated. A pathological study revealed fibrin-triggered thrombus formation that confirmed the diagnosis of nonbacterial thrombotic endocarditis. In cases of nonbacterial thrombotic endocarditis, the underlying cause should be investigated...

OBJECTIVE: To assess if the lack of development of right ventricular (RV) contractile reserve during exercise echocardiography (ex-echo) might be a predictor of postoperative major adverse cardiovascular events (MACEs) in patients with primary mitral regurgitation (pMR) undergoing early surgery. METHODS: Comprehensive resting and ex-echo were performed in 142 asymptomatic patients (58±21 years, 68% men, New York Heart Association functional class ≤2) with isolated severe pMR and preserved left ventricular (LV) function (LV ejection >60%, LV end-systolic diameter <45 mm) undergoing mitral valve replacement (n=20) or repair...

OBJECTIVE: Partial atrioventricular septal defect (pAVSD) is usually repaired between 2 and 4 years of age with excellent results. Repair during infancy has been associated with poorer outcomes. However, most infants in reported series had heart failure or significant left atrioventricular valve (LAVV) regurgitation. The impact of surgery during infancy on outcomes remains unclear. METHODS: All children at three institutions who underwent repair of pAVSD from 1975 to 2015 were included...

Mitral regurgitation (MR) is the most prevalent cause of valvular heart disease (VHD) in western countries. In the Euro Heart Survey on VHD, MR was the second most common heart VHD requiring surgery. It is also the most common form of VHD in community and population-based studies from the United States. The categorization of MR based on causes and mechanisms is a major determinant of clinical outcome, of possible therapies for the MR and of the effectiveness of these therapies. Surgical mitral valve (MV) repair has been shown to improve survival in patients with severe primary MR compared with MV replacement...

Mitral valve disease is common, with mitral regurgitation (MR) the most frequent pathology. The etiology of MR is diverse, but left untreated results in left ventricular (LV) volume overload, leading to remodeling, dilation of the LV, pulmonary hypertension, heart failure, and death. Mitral regurgitation is a high risk diagnosis, yet a minority of symptomatic patients are referred for discussion of surgical treatment options. Percutaneous repair options are under development to address this clinical need and emphasize correction of the underlying anatomical pathology to restore mitral valve coaptation...

Aortic coarctation is a congenital heart disease that causes an increased left ventricular afterload, resulting in increased systolic parietal tension, compensatory hypertrophy, and left ventricular systolic and diastolic dysfunction. The speckle tracking is a new echocardiographic technique that allows the detection of subclinic left ventricular systolic dysfunction. The aim of this study was to detect early left ventricular dysfunction using mechanical deformation by echocardiography in adults with un-repaired aortic coarctation...

Mastering the technical skills required to perform pediatric cardiac valve surgery is challenging in part due to limited opportunity for practice. Transformation of 3D echocardiographic (echo) images of congenitally abnormal heart valves to realistic physical models could allow patient-specific simulation of surgical valve repair. We compared materials, processes, and costs for 3D printing and molding of patient-specific models for visualization and surgical simulation of congenitally abnormal heart valves...

Although mitral regurgitation (MR) is prevalent in patients with end-stage heart failure, the impact of mitral valve (MV) surgery on outcomes after left ventricular assist device (LVAD) implantation and morphologic changes of MV remains unclear. We retrospectively reviewed 74 patients who underwent LVAD implantation as a bridge to transplant. Of these, 11 (15%) underwent MV repair concomitant with or prior to LVAD implantation, while 27 patients with preoperative significant (moderate or greater) MR did not undergo concomitant MV surgery...

A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b...

Mitral valve percutaneous edge-to-edge repair (PEtER) is a viable solution in high-risk patients with severe symptomatic mitral regurgitation. However, the generated double-orifice configuration poses challenges for the evaluation of the hemodynamic performance of the mitral valve and may alter flow patterns in the left ventricle (LV) during diastole. This in vitro study aims to evaluate the hemodynamic modifications following a simulated PEtER. A custom-made mitral valve was developed, and two configurations were tested: (i) a single-orifice valve with mitral regurgitation and (ii) a double-orifice mitral valve configuration following PEtER...

The development of less invasive approaches for mitral valve repair remains an important objective, particularly in patients with multiple comorbidities. We describe a novel method to affix a mitral valve annuloplasty ring in a minimally invasive manner. A delivery apparatus for an annuloplasty fastener system was designed. Two channels were created, one for advancing the annuloplasty ring, and another to accommodate the fastener applicator. Custom designed fasteners, either with a helical-shaped screw or a strap-shaped tack structure, were tested...

BACKGROUND: Occurrence of severe mitral valve (MV) regurgitation (MR) is an independent negative predictor of mortality in patients with severe systolic heart failure (HF). This study examines clinical effects and cardiac reverse remodelling in patients with severe systolic HF receiving percutaneous mitral valve repair (PMVR) using MitraClip in comparison to patients receiving optimal medical therapy only. METHODS: Between 2010 and 2014, 86 patients (Society of Thoracic Surgeons score: 10...

REVIEW
Rishi Puri, Josep Rodés-Cabau
Significant tricuspid valve disease affects many patients with left-sided heart disease. Concomitant tricuspid valve surgery for at least moderate tricuspid insufficiency is undertaken far less frequently at the time of left-sided heart surgery. The burden of residual tricuspid disease in high-surgical-risk patients has spawned the evolution of several percutaneous treatment options. A dedicated percutaneously delivered tricuspid Spacer device (FORMA Repair System) has been developed and trialed in humans. This system anchors a Spacer to reduce the regurgitant orifice area, thereby providing a surface for valve leaflet coaptation...
