Iatrogenic postoperative left ventricular outflow tract obstruction [PDF]

Clinical Cardiology, 1983
AbstractA 56‐year‐old female, who underwent aortocoronary bypass graft for occlusion of anterior descending artery is reported, who postoperatively developed a harsh systolic murmur, mitral regurgitation, and intraventricular systolic pressure gradient suggestive of hypertrophic subaortic stenosis.

Antegrade Intentional Laceration of the Anterior Mitral Leaflet to Prevent Left Ventricular Outflow Tract Obstruction

Circulation. Cardiovascular Interventions, 2020
Background: Intentional laceration of the anterior mitral leaflet (LAMPOON) is an effective adjunct to transcatheter mitral valve replacement that prevents left ventricular outflow tract (LVOT) obstruction. To date, LAMPOON has been performed in over 150

Conventional cardiopulmonary resuscitation-induced refractory cardiac arrest due to latent left ventricular outflow tract obstruction due to a sigmoid septum: a case report

Journal of Medical Case Reports, 2018
Background Patients with left ventricular outflow tract obstruction who do not exhibit a dynamic pressure gradient at rest, experience pressure gradient increases of ≥ 30 mmHg only during specific situations; this is called latent left ventricular ...

Surgical options for complex transposition of the great arteries [PDF]

, 1989
Between September 1976 and November 1987, 53 patients underwent surgical treatment by the same surgeon for “complex transposition of the great arteries” with ventricular septal defect or severe left ventricular outflow tract obstruction, or both.

Pathology of Left Ventricular Outflow Tract Obstruction [PDF]

Circulation, 1965
Lesions causing obstruction to the outflow of blood from the left ventricle may reside in the ascending aorta, the aortic valve, or the outflow tract of the left ventricle. Conditions involving the ascending aorta are usually congenital, and designated as supravalvular aortic stenosis. A tendency is present for this condition to be associated
