Congenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We sought to provide a comprehensive analysis of the current surgical techniques for treating mitral valve insufficiency and the results of mitral valve repair at our institution. Between 1972 and 2017, 104 consecutive patients underwent surgical repair of congenital MV dysplasia-insufficiency at our institution. Among these, 59 patients presented with MV insufficiency (or prevalent MV insufficiency) and were part of the study...

Introduction: Excess dilatation of the left atrium >65 mm is known in the literature as gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the left right shunt with cardiac insufficiency. Case report: In this paper is presented a case study of echocardiographically verified giant thrombus in left atrium in a 50 years old female patient aged 50 hospitalized because of tiredness, choking, heartburn and urinary tract symptoms...

BACKGROUND: Artificial chord implantation has become one of the most applied techniques for mitral valve repair (MVR). Many techniques have been described with the goal of optimizing neochord implantation. A new annuloplasty device designed to simplify the determination of appropriate neochord length has been recently introduced. We will describe our initial experience with this new device. METHODS: The semirigid device is equipped with removable loops on the posterior aspect of the ring...

Gastrointestinal bleeding with severe aortic stenosis was originally described in the 1950s by Heyde, although for years, the association was debated. Further discovery of mechanisms and the ubiquity and severity of acquired von Willebrand syndrome in the left ventricular assist device therapy have removed any doubts. At this time, gastrointestinal bleeding from intestinal angiodysplasia in patients with turbulence-related proteolysis of the highest molecular weight multimers of von Willebrand factor is now known to occur in patients with aortic stenosis, and also subaortic obstruction and associated mitral insufficiency in hypertrophic cardiomyopathy, isolated mitral and aortic insufficiency, endocarditis, and in patients with prosthetic valve dysfunction, either from stenosis or insufficiency...

PURPOSE OF REVIEW: As ventricular assist device (VAD) therapy in patients with advanced heart failure continues to grow, experience with concomitant valvular diseases present either before or after VAD implantation continues to accrue. In this review, we discuss recent data and current practice as it pertains to the subject of concomitant valvular disease in patients requiring VADs. RECENT FINDINGS: Persistent aortic valve closure has been identified as a potential contributor to aortic valve 'disuse atrophy' resulting in valve degeneration...

A 40-year-old man was transferred to our hospital following an isolated horse kick injury to the anterior chest wall. The case showed bi-fascicular block, severe tricuspid valve regurgitation due to ruptured chordae tendineae of the anterior leaflet, moderate mitral valve regurgitation due to prolapse of mitral anterior leaflet, and hypokinetic motion of the inferior septal wall. Both tricuspid and mitral insufficiency were completely repaired by a surgical operation. Fortunately, these injuries were not fatal in this case, but the comprehensive assessment of cardiac damage and careful observation are important for managing patients with cardiac injury...

BACKGROUND: There are few reports regarding factors related to late-onset of atrial fibrillation (Af) after mitral valve repair, which can compromise long-term outcome. We analyzed the risk factors for late Af after mitral valve repair. METHODS AND RESULTS: Between 2001 and 2015, 318 patients (214 males; median, 57.7 years) underwent mitral valve repair for degenerative mitral insufficiency (MI) without concomitant aortic valve disease in our institute. Patients with a history of paroxysmal or chronic Af preoperatively were excluded...

OBJECTIVES: This study hypothesized that compensatory mitral leaflet area (MLA) adaptation occurs in patients with persistent atrial fibrillation (AF) without left ventricular (LV) dysfunction but has limitations that augment mitral regurgitation (MR). The study also explored whether asymmetrical annular dilation is matched by relative leaflet enlargement. BACKGROUND: Functional MR occurs in patients with AF and isolated annular dilation, but the relationship of MLA adaptation with annular area (AA) is unknown...

REVIEW
Mark J Kearns, Keith R Walley
Cardiac tamponade is a medical emergency that can be readily reversed with timely recognition and appropriate intervention. The clinical diagnosis of cardiac tamponade requires synthesis of a constellation of otherwise non-specific features, based on an understanding of the underlying pathophysiology. Whereas echocardiographic examination is a central component of diagnosis, alone it is insufficient to establish the physiologic diagnosis of hemodynamically significant cardiac tamponade. The hemodynamic diagnosis of cardiac tamponade requires clinical evidence of low cardiac output and stroke volume in the setting of elevated cardiac filling pressures, with evidence of increased sympathetic tone (tachycardia, peripheral vasoconstriction, etc), and exclusion of other causes of shock as the primary problem (particularly cardiogenic shock)...

In neonates requiring balloon aortic valvuloplasty, both anterograde and retrograde approaches are feasible. A recent comparison of these two approaches is lacking. A retrospective cohort study of neonates at a single center undergoing BAV from 9/00 to 7/14 was performed. Records were reviewed including pre- and post-intervention echocardiograms and catheterization data. Comparisons of acute efficacy and procedural safety were made based on type of approach utilized. Forty-two neonates underwent BAV. Eleven cases utilized exclusively an anterograde approach, while 31 included a retrograde approach (including 4 with both approaches used)...

OBJECTIVES: Mitral valve (MV) repairs have been performed in paediatric patients with congenital MV stenosis. However, congenital MV stenosis lesions are a heterogeneous group of lesions, and their repair remains challenging. METHODS: From March 1999 to September 2014, MV repair was performed in 22 patients with congenital MV stenosis. The median age was 10.3 months (ranging from 22 days to 9.1 years), and the mean body weight was 7.9 ± 4.0 kg at the time of the operation...

Aims: Antegrade-transseptal approach to treat left ventricular tachyarrhythmia (LVT) is useful and widespread. Meanwhile, Mitraclip has been recently introduced as an alternative to mitral valve surgery for severe mitral regurgitation, usually coexisting with ventricular arrhythmias. However, data on the antegrade approach for mapping and ablating LVT in these patients are insufficient. We evaluated the feasibility and clinical impact of the antegrade approach for LVT after Mitraclip implantation...

The anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. The usual clinical course is severe left-sided heart failure and mitral valve insufficiency presenting during the first months of life. However, in some cases, the collateral blood supply from the right coronary artery is sufficient and symptoms may be subtle or even absent. We describe a 49-year-old woman presenting with atypical chest pain during physical exertion. The exercise tolerance test and then coronary angiography by indication revealed an anomalous origin of the left coronary artery...

Left ventricular non-compaction (cardiomyopathy) (LVN(C)) is a rare hereditary cardiac condition, resulting from abnormal embryonic myocardial development. While it mostly occurs as an isolated condition, association with other cardiovascular manifestations such as Ebstein anomaly (EA) has been reported. This congenital heart defect is characterized by downward displacement of the tricuspid valve and leads to diminished ventricular size and function. In an autosomal dominant LVN(C) family consisting of five affected individuals, of which two also presented with EA and three with mitral valve insufficiency, we pursued the genetic disease cause using whole exome sequencing (WES)...

AIMS: Evaluation of aortic stenosis(AS) is based on measurement of mean transvalvular gradient(MPG), flow velocity(vmax) and aortic valve area(AVA). Objective of the present study was to analyse the impact of systemic hemodynamic variables and concomitant mitral regurgitation(MR) on aortic MPG, vmax and AVA in severe AS. METHODS AND RESULTS: A pulsatile circulatory model was designed to study function and interdependence of stenotic aortic and insufficient mitral prosthetic valves (n=8; effective regurgitation orifice (EROA)<0...

We report a 15-month-old female with unruptured noncoronary sinus of Valsalva anreurysm (SOVA) associated with quadricuspid aortic valve, ascending aortic aneurysm (AAA), moderate aortic insufficiency, mild mitral insufficiency, genetic leukoencepaholpathy, developmental delay and mild mixed aminoaciduria. She was referred for evaluation of a cardiac murmur. Initial echocardiographic examination showed the aneurysm as a round cyst in the right atrium which changed in size during systole and diastole. As to the best of our knowledge, this is the first report of association of SOVA, quadricuspid aortic valve, AAA and genetic leukoencephalopathy in an infant...
