Right ventricular outflow tract obstruction was suspected in a 32-year-old man with repaired tetralogy of Fallot and borderline indications for surgical. heart catheterisation dobutamine stress test useful assessing the dynamics severity right determining treatment strategy.

ONE of the most characteristic clinical features of idiopathic hypertrophic subaortic stenosis (IHSS) is the striking variability in the intensity of the symptoms which accompany this disease. It has become clear recently that the severity of obstruction to left ventricular outflow is variable in IHSS and may be altered by a variety of physiological and pharmacological stimuli.' Alterations in ...

INTRODUCTION Hospitalists are frequently consulted on postoperative patients with hypotension. Postoperative hypotension is common and can be due to variety of causes. Systolic anterior motion of the mitral valve leading to left ventricular outflow tract obstruction is a rare cause of postoperative hypotension and can occur without prior structural heart disease. A high index of suspicion can l...

An unusual case of a one-day-old infant with significant left ventricular outflow obstruction produced by a pedunculated fibroma is described. The clinical findings were indistinguishable from severe valvular or subvalvular aortic stenosis. The tumor was difficult to detect by echocardiography. It produced an echo-free widening of the left ventricular outflow tract. Left ventricular cineangiogr...
