Unique Left Ventricular Outflow Tract Tunnel Lesion With a Subaortic Membranous Pouch: A Case Report
Left ventricular outflow tract obstruction (LVOTO) in children occurs at valvular, subvalvular, or supravalvular levels, with valvular lesions being the most common1. Subvalvular LVOTO lesions include thin fibrous membranes, fibromuscular ridges, and tunnel-like narrowing, occurring alone or combined, often requiring complex surgery2. LVOTO obstructs forward blood flow, causing exertional intolerance, chest pain, and arrhythmias, and may coexist with congenital lesions like ventricular septal defects3,4.
