متن کاملRight ventricular dysfunction persists following brief right ventricular pressure overload.
OBJECTIVE Acute pulmonary hypertension may cause right ventricular (RV) contractile failure. While it has been assumed that restoration of normal loading conditions after acute pulmonary hypertension is sufficient for complete recovery of RV function, this has not been rigorously examined. The purpose of this study was to test the hypothesis that acute RV pressure overload produces RV contracti...
متن کاملAcquired right ventricular outflow tract obstruction.
I t is not unusual for complicated aneurysms of the ascending aorta to affect left ventricular function. Processes causing or associated with an aneurysm may narrow the coronary artery ostia and produce myocardial ischemia or infarction; the aneurysm may distort the aortic valve ring and produce aortic insufficiency with subsequent left ventricular hypertrophy, dilatation, and failure. However,...
متن کاملAcquired left ventricular-right atrium shunts.
Left ventricular to right atrial (LV-RA) shunt is an unusual type of ventricular septal defect (VSD). This article concentrates on acquired LV-RA shunts, which may be due to complications of cardiac operation, endocarditis, trauma or myocardial infarction. A previous cardiac operation is its most common cause. The diagnosis of LV-RA communication is not easy, and it should be remembered in pati...
متن کاملDiastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex
BACKGROUND Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic fashion. METHODS Patients with symptomatic bradycardia and ACC-AHA Class I indication for permanent pacemaker implantation (PPI) were implanted a s...
