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 کاملLeft ventricular outflow tract obstruction coexisting with ventricular septal defect.
Between January 1973 and March 1982, 13 patients have been identified who had in addition to a ventricular septal defect, a discrete narrowing of the left ventricular outflow tract. Two patients had tetralogy of Fallot and one a complete atrioventricular canal defect. Two patients had previously undergone repair of a juxtaductal coarctation and one patient banding of the pulmonary artery. Eleve...
متن کاملTakotsubo cardiomyopathy and left ventricular outflow tract obstruction.
Takotsubo cardiomyopathy often presents to the cardiac catheterization laboratory masquerading as acute ST-elevation myocardial infarction (STEMI). Some of these patients present in shock secondary to dynamic left ventricular outflow tract (LVOT) obstruction. The typical patient is an elderly, hypertensive female with sigmoid deformity of the intraventricular septum. The management of hemodynam...
