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-...

background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...

conclusions sm wave in tdi is prominent and significantly high in mvp syndrome. also, our study showed some degree of diastolic dysfunction in mvp patients. results seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. as the important results of our study, sm wave was much more prominen...

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

the left ventricular aneurysm is one of the most significant complications of myocardial infarction and is defined as the expansion of the ventricular wall. the coronary artery aneurysm is characterized by an abnormal dilation of the localized portion of the coronary artery, and its main cause is atherosclerosis. we herein report an unusual case of coronary artery and left ventricular aneurysms...

background: several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (mr) in heart failure patients. we aimed to study the relationships between the severity of mr and the qrs duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. methods: w e prospectively evaluated 251 heart failure patient...

repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. it is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. this fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases. this review analyzes ...

Rheumatismal lesions of the mitral valve a!I'e rare under the age of six and surgical iruter­vention in symptomatic patients is an academic problem. Early surgical treatment has been done to prevent serious changes and unrevers­ib1e complications o.f the heart and lungs.  From April 71 until April 74, thirty-five pati­ent, ranging between 8-18 years of age, suffer­ing of <lifferents heart ,tro...

results of the 41 patients with dcm, echocardiography examination revealed 11 patients (27%) without mitral regurgitation and 12 (29%) with mild, 11 (27%) with moderate, and seven (17%) with severe mitral regurgitation. all of the morphological and functional parameters of left ventricle, atrium and mitral valve in dcm patients were greater than those in healthy subjects (all p < 0.05), except ...
