Left ventricular filling in hypertrophic cardiomyopathy. An angiographic study.
In order to study left ventricular filling in hypertrophic cardiomyopathy, left ventricular cineangiograms of 20 patients were digitised frame by frame and compared with those of 10 normal subjects. Peak left ventricular filling rate was 770+/-260 ml s-1 (mean+/-1 standard deviation), not significantly different from normal. Mitral valve opening was delayed, occurring 140+/-40 ms after time of ...
متن کاملLeft ventricular diastolic gradient in hypertrophic cardiomyopathy☆
Systolic left ventricular (LV) gradients and diastolic dysfunction are widely studied in hypertrophic cardiomyopathy (HCM) [1,2], however diastolic gradients have never been described. A patient with HCM, mid-cavity obliteration and apical aneurysm, diagnosed by both 2D echocardiography (Fig. 1, panel A) and cardiac magnetic resonance (Fig. 1, panel B), showed color Doppler aliasing effect at m...
متن کاملRegional left ventricular mechanics in hypertrophic cardiomyopathy.
BACKGROUND Nonuniformity is a determinant of diastolic function. In patients with hypertrophic cardiomyopathy, hypertrophy, abnormal calcium handling, and regional ischemia can also play a role. This study was designed to assess regional mechanics, asynchrony, and asynergy in patients with hypertrophic cardiomyopathy. METHODS AND RESULTS Nine control subjects and 22 patients with hypertrophic...
متن کاملLeft ventricular hypertrophy and hypertrophic cardiomyopathy.
eft ventricular myocardial hypertrophy (LVH) occurs in any conditions, usually, it is thought, as a secondary or compensatory” response to abnormal pressure or volume oading and to stimuli, as yet incompletely understood, esulting from deficiencies in cardiac performance (1). hese responses may be modulated by genetic predisposiions, a relationship also not well understood. “Compensaory” hypert...
متن کاملLeft ventricular relaxation and filling in hypertrophic cardiomyopathy. An echocardiographic study.
Echocardiograms showing left ventricular cavity and mitral valve cusps simultaneously were recorded in 36 patients, apex cardiograms being obtained in 26 of them. These were digitised and continuous plots made of left ventricular dimension, its rate of change, and anterior mitral leaflet velocity, and were compared with those in 20 normal subjects. Peak mitral diastolic closure rate was reduced...
