PY - 2016 TI - Alcohol septal ablation for hypertrophic obstructive cardiomyopathy in a patient with a chronic total occlusion of the right coronary artery: “beware of collateral damage” JF - Cardiovascular Diagnosis and Therapy; Vol 7, No 1 (February 01, 2017): Cardiovascular Diagnosis and Therapy Y2 - 2016 KW - N2 - Alcohol septal ablation (ASA) is an effective semi-invasive alternative to surgical myectomy in selected patients for the management of severely symptomatic and drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). One contraindication of this procedure is the presence of collateral flow originating from the target septal perforator to a remote myocardial territory. In such circumstances, ethanol injection could cause remote non-target myocardial necrosis in the collateralized territory. Percutaneous revascularization of the collateralized vessel prior to ASA might cope with this contraindication by restoring normal antegrade flow in the occluded artery. We report a case that illustrates the feasibility and efficacy of such strategy. UR - https://cdt.amegroups.org/article/view/11394
