Ts Kutova, and K Chichovski

The echocardiographic potentialities in the diagnosis of bicuspid aortic valve are discussed. In the group of 32 patients examined with a clinic and murmurs suspected for that disease, the index of excentricity in five patients, was found to be respectively 1.6, 1.4, 1.6, 1.8, 1.5, accepted as a reliable index for the diagnosis of aortic bicuspidia. Excentricity index is equal to 1/2 of the aortic diameter, divided to the minimal distance from the diastolic echo of the closed aortic valve to the closer aortic wall. The control group consisted of 44 patients with tricuspid aortic valve, 17 of them being with aortic defect (isolated stenosis or combined aortic defect) and the rest 28 -- without valvular heart disease. Excentricity index for the control group was low -- 1.0--1.33 (average value 1.28). Conclusions are drawn that the echocardiographic method, from the group of the bloodless methods, is with the best diagnostic potentialities in the bicuspid valve and should be looked for in patients with expulsion murmur and click of aortic origin.

D008944	Mitral Valve Insufficiency	Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.

D008945	Mitral Valve Prolapse	Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.

D008946	Mitral Valve Stenosis	Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.

D006347	Heart Sounds	The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of SYSTOLE and is heard as a "lubb" sound; the second is produced by the closing of the AORTIC VALVE and PULMONARY VALVE and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the HEART ATRIA; and the fourth is produced by atrial contraction and ventricular filling.
