Pulsed Doppler echocardiography was used to determine prospectively the prevalence of mitral, aortic, tricuspid and pulmonary regurgitation in 80 consecutive patients with mitral valve prolapse and 85 normal subjects with similar age and sex distribution. Mitral valve prolapse was defined by posterior systolic displacement of the mitral valve on M-mode echocardiography of 3 mm or more (40 patie...

OBJECTIVES to evaluate the structural and functional heart abnormalities in women with mitral regurgitation during pregnancy. INTRODUCTION Women with mitral regurgitation progress well during pregnancy. However, the effects on the heart of the association between pregnancy and mitral regurgitation are not well established. METHODS This is a case-control, longitudinal prospective study. Echo...

OBJECTIVE To evaluate the incidence and development of valvular regurgitation and its effect on racing performance in Standardbred trotters from 2 to 3.5 years of age. DESIGN Longitudinal observational study. ANIMALS 103 horses. PROCEDURE Horses were examined via echocardiographic imaging 4 times at 6-month intervals. Two-dimensional and M-mode echocardiographic examinations were performe...

OBJECTIVE To study the prevalence and the characteristics of physiological valve regurgitation. DESIGN Pulsed wave Doppler echocardiography, continuous wave Doppler echocardiography and Doppler colour flow mapping were performed prospectively in healthy volunteers. SETTING Echocardiography laboratory in a city hospital. PATIENTS 32 consecutive healthy volunteers (age 21-49 years, mean age...

T he prevalence of valve regurgitation in healthy people has been previously examined by echocardiography. Pulmonary regurgitation or tricuspid regurgitation (TR) was common, mitral regurgitation (MR) was less common, and aortic regurgitation was generally undetectable. In addition, the prevalence of regurgitant signals varies with age or sex. Assuming that a low prevalence of regurgitant signa...

Ischemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Echocardiographic diagnosis and assessment of ischemic mitral regurgitation are critical to gauge its adverse effects on prognosis and to attempt to tailor rational treatment strategy. There is no single approach to the echocardiographic assessment of ischemic mitral regurgitation: standard e...

We present a case of an 82-year-old male patient with history severe mitral regurgitation, aortic chronic atrial fibrillation, and suicide attempts due to depression. The underwent valvuloplasty valve replacement for regurgitation regurgitation. was extubated on the morning sixth postoperative day, but he reintubated in evening because hypotension unstable respiratory status. Echocardiography r...

OBJECTIVE To evaluate and discuss etiopathology, clinical manifestations and surgical outcome of a rare subset of unruptured aneurysm of the sinus of Valsalva which erodes into the interventricular septum. METHODS Between 1989 and 1995, seven cases of unruptured aneurysm of the sinus of Valsalva eroding into the interventricular septum underwent surgical correction at the King Edward VII Memo...

Mitral regurgitation and its haemodynamic features were investigated non-invasively in cases of hypertrophic cardiomyopathy by means of two dimensional Doppler echocardiography. There were 28 patients, 14 of whom showed systolic anterior motion (SAM) of the mitral echo; the other 14 did not. The following results were obtained. (1) Mitral regurgitation was detected by the Doppler technique in a...

OBJECTIVE To document the development of aortic regurgitation following occlusion of a patent arterial duct. DESIGN Case series involving nine children referred for surgical ligation of an isolated patent arterial duct. SETTING Academic referral centre. METHODS A preoperative transthoracic and transoesophageal echocardiogram was performed in theatre to look for aortic regurgitation. There...
