Acquired 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 کاملRight ventricular myxoma causing right ventricular outflow tract obstruction.
Cardiac myxomas are the most common neoplasms of the heart. They can be located in any chamber of the heart but frequently in the left atrium. In this report we present a patient who had been treated for a right ventricular myxoma originating from the interventricular septum and leading to right ventricular outflow tract obstruction.
متن کاملRight Ventricular Outflow Tract Obstruction in Monochorionic Twins with Selective Intrauterine Growth Restriction
Monochorionic twin pregnancies are at increased risk of perinatal mortality and morbidity due to twin-twin transfusion syndrome (TTTS), selective intrauterine growth restriction (sIUGR), and higher incidence of congenital heart malformations. The incidence of right ventricular outflow tract obstruction (RVOTO) in recipients with TTTS is known to be higher than in the general population. There i...
متن کاملAcquired right ventricular outflow tract obstruction in the recipient twin in twin-twin transfusion syndrome.
OBJECTIVES The goal of this study was to determine the prevalence and evolution of acquired right ventricular outflow tract obstruction (RVOTO) in the recipient twin in twin-twin transfusion syndrome (TTTS). BACKGROUND Twin-twin transfusion syndrome complicates 4% to 26% of diamniotic monochorionic twin gestations and is associated with high fetal morbidity and mortality. Cardiac dysfunction ...
متن کاملRight ventricular pacing for right ventricular outflow tract obstruction in a man with biventricular hypertrophic cardiomyopathy.
A 40-year-old man with known hypertrophic cardiomyopathy presented with syncope after coughing. Physical examination revealed a systolic murmur that was accentuated by the Valsalva maneuver. An electrocardiogram suggested biventricular hypertrophy and biatrial enlargement (Fig. 1). Echocardiograms revealed asymmetric septal hypertrophy with a diastolic septal thickness of 2.3 cm, and evidence o...
