The duration of left ventricular systole in mitral incompetence.
نویسندگان
چکیده
In mitral incompetence the left ventricle has two exits and it has been suggested that diminished resistance to emptying causes left ventricular systole to be shorter than normal (Brigden and Leatham, 1953). Theoretically the elevation of left ventricular end-diastolic pressure that is found in severe mitral incompetence (Ross et al., 1958; Nixon, 1961a) should result in prolongation of systole. The purpose of this communication is to report measurements of left ventricular systole in patients with mitral incompetence, and to consider their significance.

Atriogenic mitral valve reflux: diastolic mitral incompetence following isolated atrial systoles.
Cardiac and aortic pressures were recorded after stellate gangliooectomy and vagotomy. Acute heart block was produced by injecting the atrioventricular node, and atrial and ventricular systoles were controlled electronically to occur independently or in any desired relationship. Angiocardiograms recorded on video tape after injections of 4 ml 69% Renovist into the left ventricle were analyzed w...

Prolapsed Mitral Valve Syndrome is a common, benign disorder with prevalence of %0.3-6 in population. This syndrome also is known as Barlows Syndrome and Flaapy Mitral Valve Syndrome. Prolapsed Mitral Valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. This malformation leads to incomplete closing of mitral valve and regurgitates the bloo...
متن کاملReal-time sector scan study of the mitral valve prolapse syndrome.
Real-time two-dimensional sector sanning was used to analyse mitral valve motion in 4 normal subjects and 6 patients with previously diagnosed mitral valve prolapse syndromes. The normal mitral valve leaflets remain apposed for the duration of systole, and open abruptly with the onset of diastole. During diastole the leaflets are parallel to each other and only the distal ends tend to 'float' c...

Two patients, ages 14 and 18, with congenital left ventricular-right atrial communication through a defect in the tricuspid valve were studied by echocardiography. Proof was obtained by angiocardiography and surgery in one and ultrasonic contrast injection and angiocardiography in the other. Both presented clinically as uncomplicated ventricular septal defects. Echocardiography consistently dem...
متن کاملPressure-flow studies in man: effect of atrial systole on ventricular function in mitral stenosis.
The effect of atrial contraction on left ventricular function in six patients with varying degrees of mitral stenosis was determined by utilizing the pressure gradient technique to measure instantaneous aortic blood flow and pressure. Aortic flow was measured as ventricular rate was controlled by right ventricular pacing to create A-V (atrioventricular) dissociation at varying rates (90-150 bea...
