Pulsed Doppler echocardiography was employed to detect disturbed or turbulent flow diagnostic of aortic or mitral regurgitation. Sensitivity, specificity, diagnostic accuracy, and predictive value were assessed by the independent interpretation and comparison of aortic root angiograms (91 patients) and left ventriculograms (94 patients) to the time interval histogram display of the pulsed Doppl...

An accessory coronary cusp in aortic valve is a rare congenital cardiovascular malformation with an estimated incidence of 0.003 to 0.043% of all congenital heart disease. It is also describe as a quadricuspid aortic valve (QAV). Several different anatomical variations of quadricuspid aortic valve have been described. Current technology enables noninvasive diagnosis in most cases. Here we repor...

We studied the relationship between myocardial contractile state and left ventricular functional response to exercise in 14 asymptomatic patients with isolated moderate-to-severe aortic regurgitation and six control subjects. The slope of the systolic blood pressure-left ventricular endsystolic volume (pressure-volume) relationship determined by radionuclide ventriculography during angiotensin ...

quadricuspid aortic valve (qav) is an uncommon congenital anomaly which was an incidental finding during surgery or autopsy in the past. we present the case of a 44-year-old woman with moderately severe aortic regurgitation due to unequal cusp size qav diagnosed via transesophageal echocardiography. due to echocardiographic imaging improvement, the diagnosis of qav is now easier and earlier tha...

Aortic valve regurgitation is an uncommon consequence of closed chest injury. It is caused by damage to the valve apparatus (ruptured cusp) or when subadventitial rupture of the ascending aorta causes prolapse of a subjacent valve cusp. Aortic valve regurgitation was detected in 4 patients (2 men and 2 women, 30 to 65 years old) who had sustained multiple injuries in road accidents 1 week to 30...

Among 543 necropsy patients over age 14 years with severe chronic valvular heart disease, Aschoff bodies were found in 11 patients (2%). The ages of the 11 patients ranged from 18 to 68 years (avg 38), and nine had had a history of acute rheumatic fever earlier in life. Clinically, nine of the 11 patients had mitral stenosis with or without dysfunction of one or more other cardiac valves, one h...

Clinical and hemodynamic appearances of aortic regurgitation caused by serious aortic lesions (AR-Ao-group) seemed more deteriorated than those with isolated chronic aortic regurgitation (AR-group). Often postoperative course and operative outcome are smooth and satisfactory in the AR-Ao-group. To support this observation, serial changes of left ventricular (LV) function and LV sphericity were ...

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...
