The cross-sectional echocardiographic features of mitral valve prolapse were defined in 26 children (ages 2-18 years) using a real-time, multiple-crystal ultrasound scanner. In each patient the physical findings of the mitral valve click-murmur syndrome were present and mitral valve prolapse had been diagnosed previously by conventional single crystal echocardiography. Mitral prolapse occurred ...

OBJECTIVE To evaluate by echocardiography the cardiac structure and function in patients with primary adrenocortical insufficiency. DESIGN AND METHODS Two-dimensionally guided M-mode echocardiograms and spectral Doppler studies were performed in seven consecutive patients with newly diagnosed autoimmune primary adrenal failure before and 4-8 months after an adequate regimen of steroid substit...

M asterful mitral valve (MV) repair demands thorough understanding of integrated mitral apparatus structure and mechanics. One consistently reported feature, the saddle shape of the mitral annulus, was recognized in the process of resolving the contradiction posed by an apparently high prevalence of MV prolapse (MVP) in otherwise healthy individuals: A normal saddle-like shape will show opposit...

Abstract Funding Acknowledgements Type of funding sources: None. Background In MVP, MAD has been associated with myocardial replacement fibrosis and arrhythmia, but the importance interstitial remains unknown. We aimed to evaluate relationship between mitral annular disjunction (MAD) severity at left ventricular (LV) base in patients valve prolapse (MVP), assess association occurrence arrhythmi...

PURPOSE OF REVIEW To review the utility and the latest developments in three-dimensional (3D) echocardiography of mitral valve prolapse. RECENT FINDINGS Although 3D echocardiography was invented in 1974, it did not gain wide clinical acceptance until the introduction of real-time 3D echocardiography in the first decade of the 21st century. Driven by improvements in probe technology and increa...

BACKGROUND In patients with mitral valve prolapse, nonprolapsed leaflets are often apically tented. We hypothesized that secondary left ventricular dilatation attributed to primary mitral regurgitation (MR) causes papillary muscle (PM) displacement, resulting in this leaflet tenting/tethering, and that secondary tethering further exacerbates malcoaptation and contributes to MR severity. METHO...

INTRODUCTION Mitral valve prolapse syndrome (MVP) is the most common valvular abnormalityin the young and is correlated with increased frequency of cardiac dysrhythmias and sudden death.The aim of this study was to compare frequency of "early repolarization" in electrocardiogram(ECG) between MVP patients and healthy adults. METHODS In this cross-sectional study, we compared ECG presentations ...

Aim: Idiopathic mitral valve prolapsus (MVP) is characterized by myxomatous degeneration of mitral valve. The most common determinant of cardiovascular mortality in patients with MVP is left ventricular (LV) dysfunction. Therefore we aimed to evaluate LV functions of cases with isolated MVP by tissue Doppler echocardiography (TDE). Method: Twenty five patients with MVP (mean age, 31±12 years) w...

BACKGROUND Few data exist on the relation of the 3-dimensional morphology of mitral valve and degree of mitral regurgitation (MR) in mitral valve prolapse. METHODS AND RESULTS Real-time 3-dimensional transesophageal echocardiography of the mitral valve was acquired in 112 subjects, including 36 patients with mitral valve prolapse and significant MR (≥3+; MR+ group), 32 patients with mitral va...
