Libman-Sacks endocarditis is a cardiac manifestation of systemic lupus erythematosus (SLE) and antiphospholipid syndrome. We report a case of mitral valve destruction due to Libman-Sacks endocarditis, which was caused by activation of SLE, despite prompt initiation of systemic steroid therapy. The prevention of SLE activation is critically important in valve surgery for patients with SLE. To the best of our knowledge, this is the first case of repaired mitral valve destruction due to activation of SLE, which was caused by valve surgery itself...

Myxoma is the most common primary cardiac tumor and is usually located in the left atrium. Clinical manifestation relies in large part on the size, location, and architecture of the tumor. There are many reports in the literature of cardiac myxomas causing syncope, embolism, even myocardial infarction. We present a rare case of a patient who underwent urgent surgical resection of a large left atrial myxoma mimicking mitral stenosis. The postoperative course of the patient was uncomplicated. One year after surgery, the patient is asymptomatic and disease-free...

Extracellular matrices (ECM) are commonly used to repair congenital heart defects; however, there is a lack of literature pertaining to outcomes with ECM use in high-pressure conditions. Between 2011 and 2014, a total of 202 patients underwent congenital heart disease repair using the ECM placed in a systemic pressure condition. The operative sites included: defects in the ventricular septum, mitral valve, aortic valve, ascending aorta, and aortic arch. Patients were followed and evaluated for mortality and reoperations due to loss of ECM integrity...

The tricuspid valve (TV), although occasionally considered "neglected" is the subject of renewed and increasing interest. Factors include an awareness that tricuspid value dysfunction is influential in patient outcomes, an improving understanding of valve anatomy and function and evolving techniques available to address tricuspid regurgitation. Tricuspid regurgitation (TR) can be classified as being due to primary diseases of the valve or functional in nature, with the majority being functional. Whilst it was previously believed that such functional TR, resulting from left sided disease, would resolve after correction of the underlying pathology this is now known not to be true...

Fungal endocarditis (FE) is a rare and fatal disease. The contemporary in-hospital and long-term surgical outcomes of FE have not been adequately evaluated. This study describes our experience with the surgical management of FE.Eight FE patients who underwent surgery in our center from January 2004 to November 2016 were included in this study. Seven had fungal prosthetic valve endocarditis (PVE) and one fungal native valve endocarditis (NVE). The Bentall operation, Cabrol operation, and mitral valve replacement were performed in 4, 3, and 1 patient, respectively...

Mitral valve (MV) repair with artificial chordae (AC) or leaflet resection (LR) is associated with good hemodynamics at rest. The aim of this study was to compare these techniques in terms of exercise capacity and echocardiographic parameters of hemodynamics at rest and peak exercise. We conducted a study in 2015 of 56 patients, who had undergone surgery for degenerative posterior mitral leaflet prolapse between 2005 and 2014 using either AC (n = 24) or LR (n = 32). Clinical data were collected, exercise capacity was measured, and resting echocardiography and peak exercise echocardiography were performed...

BACKGROUND: A comprehensive evaluation of mitral stenosis (MS) severity commonly utilizes two-dimensional (2D) echocardiography techniques. However, the complex three-dimensional (3D) structure of the mitral valve (MV) poses challenges to accurate measurements of its orifice area by 2D imaging modalities. We aimed to assess MS severity by comparing measurements of the MV orifice area using conventional echocardiography methods to 3D orifice area (3DOA), a novel echocardiographic technique which minimizes geometric assumptions...

INTRODUCTION: Percutaneous mitral valve repair (PMVR) using MitraClip system has emerged as a therapeutic option for patients with functional severe mitral regurgitation (FMR) at prohibitive risk for surgery. In this setting, the echocardiographic assessment of FMR severity is challenging because the traditional echocardiographic methods have important limitations. The aim of this study was to assess the accuracy and reliability of a simple Doppler index, the mitral/aortic flow velocity integral ratio (MAVIR), to evaluate residual FMR severity after PMVR...

INTRODUCTION AND OBJECTIVES: Paravalvular leak (PVL) is a possible complication after prosthetic valve implantation. PVL can cause significant symptoms of congestive heart failure and/or hemolysis. Medical therapy is palliative and reoperation has a high mortality rate. Percutaneous transcatheter closure is a promising alternative for symptomatic patients at high surgical risk. We aim to review the efficacy and safety of percutaneous PVL closure in a consecutive series of patients referred to our center...

Patients undergoing cardiac valve replacement may receive mechanical or bioprosthetic valves. Mechanical valves require lifelong anticoagulation but are durable and the need for a second surgery is up to eightfold times less than with bioprosthetic valves. Bioprosthetic valves do not require lifelong anticoagulation and thus are associated with fewer bleeding complications but they are less durable and associated with higher morbidity and mortality rates, particularly in younger patients. Anticoagulation with mechanical valves is achieved using warfarin; use of direct-acting oral anticoagulants is not indicated...

BACKGROUND: Surgical ablation (SA) for atrial fibrillation (AF) effectively restores sinus rhythm. Incompletely defined risk has previously limited concomitant performance of SA during cardiac operations. The study goals were to define performance trends and risk-adjusted outcomes for contemporary SA. METHODS: From July 2011 to June 2014, 86,941 patients with AF, but without endocarditis, underwent primary nonemergent cardiac operations in The Society of Thoracic Surgeons (STS) database...

OBJECTIVE: To understand the impact of the Hospital Readmission Reduction Program on both future targeted and nontargeted surgical procedures. BACKGROUND: The Hospital Readmission Reduction Program, established under the Affordable Care Act in March of 2010, placed financial penalties on hospitals with higher than expected rates of readmission beginning in 2012 for targeted medical conditions. Multiple studies have suggested a "spill-over" effect into other conditions, but the extent of that effect for specific surgical procedures is unknown...

BACKGROUND: Marfan syndrome (MFS) is a multisystemic hereditary connective tissue disease. Aortic root aneurysms and dissections are the most common and life-threatening cardiovascular disorders affecting these patients. Other cardiac manifestations include mitral valve prolapse, ventricular dysfunction and arrhythmias. Medical treatment of cardiovascular features is ultimately aimed at slowing down aortic root growth rate and preventing dissection. Losartan has been proposed as a new therapeutic tool for this purpose...

The mitral valve apparatus, both functionally and morphologically is composed of a constellation of individual structures, including the annulus, anterior and posterior leaflets, chordae tendineae, and papillary muscles. Most also include the left ventricular wall and the left atrium which are essential for the valve to function normally. Areas covered: The commonest conditions responsible for mitral valve dysfunction in the Western World are degenerative and functional mitral regurgitation, which are discussed in detail...
