Left Ventricular Outflow Tract Obstruction
Patients with hypertrophic cardiomyopathy (i.e., asymmetric septal hypertrophy) may show obstruction to left ventricular outflow under basal conditions or with provocative maneuvers. The presence of dynamic left ventricular outflow tract obstruction in patients with concentric ventricular wall thickening (but without abnormalities of the aortic valve) has been less well appreciated. Clinical an...
متن کاملPathology of Left Ventricular Outflow Tract Obstruction.
THE anatomic sites at which obstruction to the egress of blood from the left ventricle may occur are three in number, as follows (fig. 1): the aorta, the aortic valve, and the subaortic region of the left ventricle. Obstruction in the aorta may involve one of two general areas, namely, (1) the arch or just beyond, the lesions taking the forms of classical coarctation, tubular hypoplasia, or int...
متن کامل[Dynamic left ventricular outflow tract obstruction induced by exercise].
INTRODUCTION AND OBJECTIVES Dynamic left intraventricular outflow tract obstruction occurs occasionally in patients without hypertrophic cardiomyopathy. We hypothesized that dynamic intraventricular obstruction might occur during effort in patients with angina or dyspnea without evident disease. The objective of this prospective study was to investigate: a) whether it appears with effort; b) it...

متن کاملDynamic left ventricular outflow tract obstruction in senile cardiac amyloidosis.
Dynamic left ventricular outflow tract (LVOT) obstruction is classically seen in hypertrophic obstructive cardiomyopathy (HOCM). This can also be seen in cardiac amyloidosis. We describe a rare case of senile systemic amyloidosis with dynamic LVOT obstruction and concomitant three vessel coronary artery disease presenting with clinical and echocardiographic findings similar to those seen in HOC...
