background: the adult cardiac surgery databank (acsd) of tehran heart center was established in 2002 with a view to providing clinical prediction rules for outcomes of cardiac procedures, developing risk score systems, and devising clinical guidelines. this is a general analysis of the collected data. methods: all the patients referred to tehran heart center for any kind of heart surgery betwee...
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-...
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...

Introduction: Observing microembolic signals in brain vessels by transcranial Doppler technology is a very common finding in patients with mechanical heart valve. These signals are almost always clinically asymptomatic. The aim of this study was assessment of transcranial Doppler in detecting probability of stroke in patients with mechanical heart valve. Methods: This descriptive study was ca...
we report two cases of tetralogy of fallot with pulmonary valve bacterial endocarditis where one extended to the branch of pulmonary artery (pa). this is a rare occurrence. aggressive supportive care plus early and radical surgery can be life saving.
This research is a field study designed to-investigate the complication of patients, who underwent heart valve Surgery and were hospitalized in intensive care unit. In this research, the field files of those patient who had undergone surgical heart valve operation and were hospitalized in intensive care units in 1992, have been selected as general research documents. From the point of...
