Surgical valve replacement after infective endocarditis can result in local destructive paravalvular lesions. A 30-year-old woman with infective endocarditis underwent mitral valve replacement that was complicated postoperatively by 2 paravalvular leaks. During percutaneous closure of the leaks, a Gerbode defect was also found and closed. We discuss our patient's case and its relation to others in the relevant medical literature. To our knowledge, we are the first to describe the use of a percutaneous approach to close concomitant paravalvular leaks and a Gerbode defect...

PURPOSE OF REVIEW: This review examines the current status of catheter-based repair and replacement for mitral valve disease, with a focus on native primary and secondary mitral valve regurgitation. RECENT FINDINGS: Transcatheter mitral valve repair with the MitraClip®, with >40,000 performed procedures worldwide, has significantly advanced the field of transcatheter therapy for mitral valve regurgitation. Transcatheter mitral valve replacement remains in the early stages of development, mainly due to the complex anatomy and physiology of the mitral valve...

BACKGROUND A free-floating ball thrombus in the left atrium is a rare clinical condition. However, the diagnosis of this condition has been facilitated by the advent and development of echocardiography and multi-detector row computed tomography (MDCT) and several cases have been reported. CASE REPORT We report a case of a 75-year-old woman who had recurrent giant spherical thrombi in the left atrium. She was diagnosed with chronic atrial fibrillation at 52 years of age. A pacemaker implantation was performed at 54 years of age because of a complete atrioventricular block; and mitral valve replacement was performed for severe mitral regurgitation at 62 years of age...

BACKGROUND: Net atrioventricular compliance (Cn), a parameter for the net compliance of the left atrium and left ventricle, is known to be a useful predictor of outcomes in patients with mitral stenosis (MS). The present study aimed to evaluate whether the impact of Cn on symptom status and clinical outcomes, as well as its contribution toward systolic pulmonary artery pressure (SPAP), differed according to cardiac rhythm. METHODS: We retrospectively reviewed patients (N = 308) with rheumatic pure MS...

Mitral stenosis is often managed percutaneously with an interventional procedure such as balloon commissurotomy. Although this often results in an increased mitral valve area and improved clinical symptoms, this procedure is not benign and may have serious complications including the development of hemodynamically significant mitral valve regurgitation. Multiple scoring systems have been developed to attempt to risk stratify these patients prior to their procedure. CASE: A 64-year-old patient underwent an emergent mitral valve replacement after having percutaneous mitral balloon commissurotomy complicated by development of severe mitral regurgitation...

INTRODUCTION: The mitral valve area (MVA) poorly reflects the hemodynamic status of (MS). In this study, we compared the MVA with mitral valve resistance (MVR) with regard to the determination of hemodynamic consequences of MS and the immediate outcomes of percutaneous balloon mitral valvuloplasty (PBMV). METHODS: In a prospective study, 36 patients with severe rheumatic MS with left ventricular ejection fraction (LVEF) >50% were evaluated. They underwent transthoracic echocardiography (TTE) and catheterization...

Paravalvular leak (PVL) following aortic valve implantation is a rare complication but may cause potentially serious consequences. It occurs in 2%-10% of surgical aortic valve replacements and 7%-17% of surgical mitral valve replacements. Transcatheter valve replacement data show that significant PVL occurs in 6%-8% of cases. The management of significant PVL has traditionally involved repeat surgical repair. However, many of these patients are considered too high risk to undergo a repeat surgical procedure; hence, a percutaneous transcatheter approach has often been utilized to treat these patients...

A 59-year-old male with a history of mitral valve replacement several years previously was admitted to the authors' institution with symptoms of advanced heart failure. Echocardiography showed a severe paravalvular dehiscence and surgery was discouraged due to high perioperative risk. A first transcatheter leak closure was unsuccessful despite the correct deployment of various occluding devices. A second percutaneous attempt was carried out with implantation of three Amplatzer Vascular Plug® III devices (five occluders were positioned in total within the oblong defect), leading to a mild residual leakage...

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...
