Echocardiography has been accepted as the diagnostic modality of choice for mitral valve prolapse (MVP). The determine the effect of position on echocardiographic diagnosis of MVP, we examined 693 consecutive patients referred to the echocardiography laboratory because of suspected MVP. First, patients were examined using the usual standard M-Mode echocardiography( left parasternal third or fou...

In this study, 103 Saudi males and 172 Saudi females were referred for medical check-up for employment purposes and/or as undergraduate students. Clinical evaluation of all participants included full cardiovascular examination, with the following investigations being performed: ECG, chest x-ray, and cross-sectional echocardiography. Bicuspid aortic valve was detected in three males and in four ...

An interatrial septal aneurysm is a localized segment of the interatrial septum that bulges into either or both the left and right atrium [1,2]. The clinical importance of such an interatrial septal aneurysm is that itmay be confusedwith an atrial tumor [2], it may be the cause of supraventricular arrhythmias [3] and it has a strong association with cryptogenic stroke in the young [4]. A review...

To better understand the association between mitral regurgitation and secundum atrial septal defect and to clarify the evaluation and management of these patients, the records of 235 adult patients with atrial septal defect were reviewed. Ten patients (4 percent) had significant mitral regurgitation defined by clinical, hemodynamic and angiographic criteria. Three patients required mitral valve...

The prevalence of mitral valve prolapse was determined in two independent populations (6887 consecutive adults and children referred for echocardiography during a three year period and 206 non-referred first degree relatives of 65 patients with mitral valve prolapse). In the 118 adults with echocardiographic evidence of prolapse those aged greater than or equal to 50 years were significantly mo...

The hearts of three children who died with Duchenne's progressive muscular dystrophy and features of mitral valve prolapse were examined to find if the valve disorder arose from cardiomyopathy due to the primary disease or from dystrophic changes in th mitral valve itself. Gross, histologic and ultrastructural features of mitral valve annulus, anterior and posterior leaflets, chordae tendineae,...

Real-time, phased-array, two-dimensional echocardiographic studies identified ruptured chordae tendineae in five patients: four patients had a flail mitral valve and one had flail mitral and tricuspid valves. The characteristic abnormality was a rapid systolic motion of the involved leaflet beyond the line of valve closure into the atrium. The maximal abnormal systolic motion was greatest at th...

Degenerative mitral valve disease is responsible for the syndromes of billowing mitral leaflet, mitral valve prolapse (MVP), floppy mitral valve, and flail leaflet. The pathology of these is mainly caused by myxomatous infiltration and fibroelastic deficiency. In the 1960s, Reid and Barlow and colleagues proposed that mid to late systolic clicks and apical late systolic murmurs were of mitral v...

Echocardiographic and phonocardiographic findings in 35 patients with Marfan's Syndrome and ten patients without Marfan's or other clinically apparent connective tissue disorders but with angiographic and echocardiographic evidence of mitral prolapse are reported and compared. Echocardiography revealed aortic root dilatation and/or mitral valve prolapse in 97% of the patients with Marfan's Synd...
