To test the hypothesis that the fall in supravalvular aortic diastolic pressure is relative to the severity of the regurgitant flow in aortic regurgitation, 27 patients with isolated aortic regurgitation, 23 patients with combined aortic regurgitation and stenosis, and 15 normal subjects were studied. Diastolic pulse pressure (pressure at the dicrotic notch minus pressure at end diastole) and t...

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...

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 valve areas determined by Doppler pressure half-time were compared with areas obtained by planimetry in two groups of patients with mitral stenosis: 24 patients without aortic regurgitation and 32 patients with more than grade 1 aortic regurgitation. The severity of aortic regurgitation was assessed by color flow mapping; 17 patients had grade 2, 10 had grade 3 and 5 had grade 4 aortic r...

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...

BACKGROUND Human tissue valves for aortic valve replacement have a limited durability that is influenced by interrelated determinants. Hierarchical linear modeling was used to analyze the relation between these determinants of durability and valve regurgitation measured by serial echocardiography. METHODS AND RESULTS In adult patients, 218 cryopreserved aortic allografts were implanted with t...

BACKGROUND Bicuspid aortic valve regurgitation can be caused by a defect in the valve itself or by dysfunction of one or more components of the aortic root complex. A successful repair thus requires correction of all aspects of the problem simultaneously. We review our experience addressing both the valve and the aortic root when correcting bicuspid valve regurgitation. METHODS AND RESULTS Be...

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...

Aortic valve repair with either the reimplantation of aortic or root remodelling external annuloplasty procedure is most effective means treating regurgitation and/or aneurysms [...]
