Severe aortic insufficiency may accelerate mitral valve closure. We noted this echocardiographic finding in several patients with the acute onset of severe aortic insufficiency. Accordingly, we examined our total echocardiographic series retrospectively for early closure of the mitral valve (ECMV) in the setting of aortic insufficiency and found it in 11 of 53 patients with confirmed aortic ins...

a seven-year-old girl with clinical diagnosis of aortic insufficiency underwent echocardiographic and hemodynamic evaluation and referred for surgery with the same diagnosis. however, at surgery, aorto-ieft ventricular tunnel was found and repaired successfully. review of echocardiogram and catheterization data revealed interesting findings to differentiate this rare entity from congenital aort...

a 32-year-old female patient with previous bentall operation and mitral valve repair surgery due to severe aortic insufficiency, mitral valve insufficiency, and ascending aortic aneurysm was admitted to our hospital with serious dyspnea, fatigue, and mild chest pain. two-dimensional echocardiography demonstrated a markedly dilated basal aorta and cardiac chambers. thoracic computed tomography s...

background: discrete subaortic stenosis (dss) is a progressive condition. controversy still rumbles on as to whether the subaortic membrane causes aortic regurgitation (ar) and whether membrane resection reduces ar severity. we investigated the association between the left ventricular outflow tract peak gradient (lvot-pg) and ar severity preoperatively and changes in ar severity and obstruction...

Cardiac disease is rare in patients with Reiter's syndrome. There have been 15 reported cases of aortic insufficiency in patients with Reiter's syndrome, with the aortic insufficiency developing over several years. This paper reports the case of a black HLA-B27 negative woman who presented with Reiter's syndrome and acute aortic insufficiency. An antecedent streptococcal infection is suggested ...

OBJECTIVES We sought to create a model of aortic insufficiency in a left heart simulator combined with 3-dimensional echocardiography and finite element modeling of the aortic valve. We examined the effects of aortic root geometry alteration on aortic insufficiency. METHODS Porcine aortic roots were analyzed on a left heart simulator before (control, n = 8) and after intervention (n = 8). Int...

To assess the usefulness of continuous wave Doppler echocardiography in the evaluation of aortic insufficiency, the aortic regurgitant flow velocity pattern obtained with continuous wave Doppler examination was compared with the results of aortography and conventional pulsed Doppler techniques in 25 individuals with aortic insufficiency. The diastolic deceleration slope as measured from the con...

THE experimental production of sudden, severe aortic insufficiency causes left ven-tricular diastolic pressure to become markedly elevated so that it exceeds left atrial pressure and results in diastolic closure of the mitral valve.' Ten cases of severe aortic insuffi-ciency have been reported in which left ven-tricular pressure exceeded left atrial pressure during diastole, causing premature m...
