Hemodynamic and Angiographic Evaluation of Aortic Regurgitation
نویسندگان
چکیده
Eighteen patients with chronic aortic insufficiency were evaluated hemodynamically and angiographically 8 months after aortic valve replacement. Both the pulmonary artery diastolic pressure and the left ventricular end-diastolic volume decreased significantly (p < 0.001), but the mean ejection fraction and the cardiac output remained identically lowered, though some individual cases showed improvement. The relative reduction in end-diastolic volume correlated only with the preoperative ejection (p < 0.05) and regurgitation fractions (p < 0.02). In the 10 patients whose left ventricular volume remained high or ejection fraction low, a second evaluation

AORTO-LEFT VENTRICULAR TUNNEL. A CASE REPORT WITH AORTIC PRESSURE AND ECHOCARDIOGRAPHIC FINDINGS
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...
متن کاملMitral valve E point-septal separation as an index of left ventricular function with valvular heart disease.
Echocardiographic mitral valve E point-septal separation (EPSS) has been found to be a useful hemodynamic index. Prior studies have shown a high negative correlation between EPSS and left ventricular ejection fraction (EF) in selected patients, but the utility of this index with valvular heart disease has not been examined in detail. Cardiac catheterization and M-mode echocardiographic data wer...
متن کاملMid-diastolic aortic valve opening in severe acute aortic regurgitation.
A case of severe acute aortic regurgitation is reported. Echocardiographic findings included mid-diastolic opening of the aortic valve, premature closure of the mitral valve, diastolic shuddering of the anterior mitral leaflet, probable demonstration of the flail aortic cusp in the left ventricular outflow tract, and increased left atrial and left ventricular dimensions. Correlation with hemody...
متن کاملQuantitative assessment of the hemodynamic consequences of aortic regurgitation by means of continuous wave Doppler recordings.
The purpose of this study was to evaluate the ability of continuous wave Doppler ultrasound recordings to reflect the magnitude and hemodynamic effects of aortic regurgitation. Forty-five patients with angiographically proved aortic regurgitation had Doppler studies performed within 24 hours of cardiac catheterization. High quality spectral recordings of the regurgitant jet were obtained in 31 ...

Although classic and standard procedure for patients with ascending Aorta aneurysm with Sever aortic Regurgitation is Bentall surgery but in some selected cases this complex surgery was not performed with different reason like advanced age and coexisting comorbidity involving renal and hepatic and lung Function. In our cases 75 years old man with chronic renal failure ( Cr= 3.2 ) who was known ...
