background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

Fifty consecutive patients having had cardiac catheterisation for coronary artery disease also underwent testing by three non-invasive methods commonly employed for assessment of left ventricular function. These included the first pass radionuclide ejection fraction, fractional shortening of the M-mode echocardiographic left ventricular internal dimension, and pre-ejection period/left ventricul...

Amyloid cardiomyopathy is characterized by non-dilated thick-walled left ventricular, thickening of interventricular septum and right ventricular free wall, biatrial enlargement associated with granular 'sparkling' appearance of the myocardium. Typically, decreased left ventricular compliance results in abnormal diastolic functions but left ventricular systolic functions are preserved until lat...

breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. labrador retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. so, the present study was aimed to determine the m-mode...

OBJECTIVE To study the pre-operative level of left ventricular ejection fraction that may be indicative of an increased risk of early and late mortality and of recurrent angina pectoris and late non-fatal myocardial infarction. MATERIAL AND METHODS A total of 934 patients with known left ventricular ejection fraction, 80 women and 854 men, were submitted to coronary artery bypass grafting at ...

We read with great interest the article by Falase et al. in the November 2012 issue of this journal. They stated that there are no documented cases of left ventricular non-compaction in Africa. Furthermore, they propose that this is due to a lack of awareness of this condition among African cardiologists. The purpose of this letter is to highlight that this statement is not entirely accurate. I...
