Video Supplement to “Hypertrophic Obstructive Cardiomyopathy Requiring Ablation via Septals From Both Left and Right Coronary Arteries – A Case Report and Review of Literature,” by Alomar, et al. (August 2020 Brief Communication).
A 60-year-old female with hypertrophic obstructive cardiomyopathy (HOCM) was referred for alcohol septal ablation due to exertional dyspnea despite optimal medical management. Echocardiography showed a mean left ventricle to aortic pressure gradient of 105 mm Hg and severe mitral regurgitation due to systolic anterior motion of the mitral valve. The following angiography series of the patient's left heart catheterization shows septal perforators originating from the proximal segment of the right coronary artery and left anterior descending artery.
