We report a rare case of papillary muscle rupture due to myocardial infarction during left ventricular assist device support. A 69-year-old woman with cardiogenic shock due to acute myocardial infarction requiring venoarterial extracorporeal membrane oxygenation support was transferred for further surgical intervention. Six days after the event, extracorporeal membrane oxygenation was decannulated, and an extracorporeal left ventricular assist device was implanted. On postoperative day 11, she suffered from sudden onset hypoxia due to pulmonary edema...

BACKGROUND: Automatic quantification of real-time three-dimensional (3D) full-volume color Doppler transthoracic echocardiography (FVCD) has been proposed as a feasible and accurate method for quantifying MR. We aimed to explore the clinical implications of real-time 3D-FVCD for mitral regurgitation (MR) with various clinical manifestations, in comparison with the conventional two-dimensional (2D) proximal isovelocity surface area (PISA) and volumetric method and cardiac magnetic resonance imaging (CMR) methods...

The unique features of ischemic mitral regurgitation may necessitate attention to certain points during mitral valve replacement (MVR). A few simple but practical recommendations are offered for concomitant or isolated MVR in this high-risk population which is often burdened by an extremely limited myocardial reserve.

BACKGROUND: A possible relationship between an obstructive prosthesis and suboptimal hemodynamic recovery, as reflected by unsatisfactory regression in systolic pulmonary artery pressure (sPAP) and functional tricuspid regurgitation (FTR) following mitral valve replacement (MVR), was investigated. A delineating effective orifice area index (EOAI) value was sought in order to define a patient-prosthesis mismatch. METHODS: A total of 128 patients undergoing isolated mechanical MVR were followed up for a mean of 46 ± 9 months...

BACKGROUND: Mitral chordae tendineae rupture (MCTR) is a progressive disorder which leads to severe mitral regurgitation. Despite its importance, the precise pathogenetic mechanism of MCTR remains unclear. The study aim was to investigate the expression profile of circulating microRNAs (miRNAs) as being potentially involved in the development of MCTR. METHODS: Twenty-one patients with 'primary' MCTR, and 30 age- and gender-matched controls, were enrolled in the study...

Double-orifice mitral valve (DOMV) is a relatively rare cardiac anomaly. Although usually associated with various cardiac anomalies, co-presence of DOMV and noncompaction of left ventricular myocardium (NCLVM) is extremely rare. Here, we present a 24-year-old male who underwent mitral valve repair using artificial chordae and annuloplasty at the posterior commissure for severe mitral regurgitation (MR), resulting from flail anterior leaflet of the larger postero-medial orifice and dilatation of left ventricle with NCLVM...

Numerous patients are treated with the MitraClip, although they do not fulfill the stringent inclusion criteria of the Endovascular Valve Edge-to-Edge Repair Study (EVEREST) trials. The outcome of those patients is not well known. Therefore, we compared the long-term outcome after MitraClip treatment between patients who matched (group 1) and did not match (group 2) the EVEREST criteria. One hundred thirty-four consecutive patients were treated from September 2009 to July 2012: 59 patients (44%) in group 1 versus 75 patients (56%) in group 2...

The strategy for the management of adult patients with congenital heart disease (CHD) often represents a challenge for cardiac surgeons and cardiologists due to complex anatomy, wide range of clinical presentations, and a high-risk profile. However, hybrid approach may represent an attractive solution. We report three cases of adult patients previously operated for CHD and recently treated with a hybrid approach in our institution. Case 1: a 76-year-old woman with permanent atrial fibrillation, lung disease, chronic kidney disease, microcytic anemia, and type II diabetes mellitus, previously operated for atrial septal defect closure and pulmonary valvotomy, presented with severe pulmonary regurgitation and advanced right ventricular failure...

The mitral valve disease (MVD) in Lutembacher's syndrome has been infrequently analyzed from a pathological standpoint. In this study, we have attempted to elucidate the pathology of MVD in this interesting syndrome in 44 autopsied cases of combined non-primum atrial septal defect (ASD) and MVD collected over 16 years. The patients were divided into 3 groups: Group 1: non-primum ASD with clinically diagnosed mitral stenosis (MS)±regurgitation, Group 2: non-primum ASD with clinically diagnosed mitral regurgitation (MR) and, Group 3: non-primum ASD with no clinically evident MVD, but with mitral valve pathology diagnosed at autopsy...

Owing to its efficiency and cost effectiveness, auscultation using a stethoscope is the primary diagnosis method preferred by most medical examiners for cardiovascular disease. Phonocardiography (PCG) is the next level of auscultation and an effective analysis technique in cardiology. This paper presents a method to quantify Mitral Regurgitation (MR) using PCG. MR is one of the most common cardiovascular diseases associated with a defect in mitral valve. We analyzed the multifractal nature of heart sounds with murmur followed by classification and clustering using Hurst exponents...

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia and despite obvious clinical importance remains its pathogenesis only partially explained. A relation between inflammation and AF has been suggested by findings of increased inflammatory markers in AF patients. OBJECTIVE: The goal of this study was to characterize morphologically and functionally CD45-positive inflammatory cell populations in atrial myocardium of patients with AF as compared to sinus rhythm (SR)...

BACKGROUND: Tricuspid regurgitation (TR) often accompanies ischemic mitral regurgitation and is generally assumed to be a secondary consequence of altered hemodynamics of the left-sided regurgitation. We hypothesized that it may also be a direct consequence of right-sided ischemic disease. Therefore, our objectives were to (1) characterize the nature of this TR and (2) describe its time course after mitral valve surgery for ischemic mitral regurgitation, with or without concomitant tricuspid valve repair...

MitraClip (MC) is an alternative therapeutic option for patients with severe mitral regurgitation (MR) who are at high surgical risk. Most candidates for MC have severe heart failure (HF) with increased N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels. We sought to clarify the response of NT-pro BNP after MC and to identify the determinants of NT-pro BNP nonresponders. Among 136 consecutive patients successfully treated with MC, we excluded 20 patients due to low baseline NT-pro BNP levels and therefore examined 116 patients...
