from may 1994 to december 1996 thirty patients received viable fresh aortic homografts. mean age was 55 years (13 to 70), male to female ratio was 2/1, 24 operations were elective whereas 6 were semiurgent. predominant lesions were aortic stenosis or regurgitation in lb patients, aortic valve endocarditis in 10, prosthetic valve dysfunction in 3, and aortic root pathology in one patient. from t...

bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. sinus of valsalva aneurysm is an uncommon complicatio...

Mitral and aortic valve regurgitation both lead to left ventricle volume overload, but have different pathophysiology. Preload is increased in mitral regurgitation whereas afterload is normal since part of the ejection flow goes to the left atrium; however, both preand afterload are increased in aortic regurgitation. When the regurgitations are chronic, the ventricle adapts by increasing the vo...

OBJECTIVES This study sought to report on the feasibility and early results of transcatheter aortic valve implantation employing a second-generation device in a series of patients with pure aortic regurgitation. BACKGROUND Efficacy and safety of transcatheter aortic valve implantation in patients with calcific aortic stenosis and high surgical risk has been demonstrated. However, experience w...

Background The quantification of valvular regurgitation by CMR is usually a second-line diagnostic tool that is used when echocardiography has proven inconclusive. According to guidelines are aortic and mitral regurgitations considered severe if the regurgitation volume > 60 ml and regurgitation fraction > 50 %. Regurgitation of a single heart valve may be calculated by comparing LVSV and RVSV ...

We described our mid-term results in repairing prolapsing aortic cusps in 21 patients with aortic regurgitation and normal aortic root morphology. Aortic regurgitation was moderate-severe in five patients and severe in 16 patients. Prolapse involved the left cusp in four patients (19%), the right cusp in 10 patients (47%) and the non-coronary cusp in 7 (33%) patients. Correction of the prolapsi...

BACKGROUND Prosthetic valve detachment after aortic valve replacement and pseudoaneurysm formation are the most important postoperative complications in patients with Takayasu arteritis with aortic regurgitation. We reviewed our experience of surgical treatment of aortic regurgitation in patients with Takayasu disease. METHODS Between November 1997 and September 2011, 11 patients (4 women and...

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...

Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy. Transthoracic echocardiography revealed dilation of the left ventricle, valvular and subvalvular aortic stenosis, bicuspid aortic valve, aortic regurgitation, and mitral valve ...

Although aortic regurgitation is a diastolic phenomenon, it has been observed during systole in a few cases. Our aims were to determine the incidence of systolic aortic regurgitation in routine clinical practice and to investigate the clinical profiles of patients with the condition. An exhaustive prospective study of all investigations performed by a hospital echocardiographic unit over one mo...
