Key result
Surgical treatment successfully manages coexisting obstructive HCM and LAD myocardial bridging.
Why the study?
Myocardial bridging causing compression of major coronary arteries is a potential cause of myocardial ischemia in patients with hypertrophic cardiomyopathy, but surgical treatment is rarely required and not well described.
Case Report (n=1)
This case report describes the surgical management of a patient with concurrent obstructive hypertrophic cardiomyopathy and myocardial bridging of the left anterior descending artery.
May support combined surgical management in select obstructive HCM cases with LAD bridging; hypothesis-generating and requires prospective validation before wider adoption.
Myocardial bridging is often detected during diagnostic coronary angiography in patients with congenital and acquired heart defects. In most cases, muscle bridging does not require surgical treatment. Myocardial bridging and tunnels causing compression of one or more major coronary arteries is a potential cause of myocardial ischemia in patients with hypertrophic cardiomyopathy. The authors report surgical treatment of a patient with obstructive hypertrophic cardiomyopathy and myocardial bridging of the left anterior descending artery.

Lysenko et al. (2022) conducted a case report in Obstructive hypertrophic cardiomyopathy and myocardial bridging of the left anterior descending artery (n=1). Surgical treatment was evaluated. Surgical treatment was reported for a patient with obstructive hypertrophic cardiomyopathy and myocardial bridging of the left anterior descending artery.
