Obstructive Lesions of the Left Ventricular Outflow Tract
FOR YEARS successful surgical treatment of obstructive lesions of the left ventricular outflow tract lagged behind the often brilliant results obtained for more than 15 years in correction of inflow obstruction to the left ventricle at the mitral valve. Closed operations for relief of aortic valve obstruction gave early promise, but results were unpredictable, relief was usually temporary, and ...
متن کاملLeft Ventricular Outflow Tract Tachycardias
Left ventricular outflow tract tachycardia (LVOT-VT) is an uncommon type of idiopathic left ventricular tachycardia (ILVT) thought to be due to cyclic adenosine mono phosphate (cAMP) mediated triggered activity. The arrhythmia can be terminated pharmacologically with calcium channel blockers or beta-blockers [1]. LVOT-VT can arise above or below the coronary cusps and the former variety can als...
متن کاملLeft 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 کاملAppearance of the interventricular septum in obstructive lesions of the left ventricular outflow tract.
Measurements of the thickness of the septum were made in 26 cardiac specimens and in 13 patients. There were 10 normal specimens, five with aortic stenosis, two with asymmetric septal hypertrophy, four with hypertensive cardiovascular disease, and five with idiopathic cardiomyopathy. Patient measurements were obtained by visualizing the septum during simultaneous left and right ventriculography...
