Coil Embolization of Septal Branches inHypertrophic Obstructive Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) has been associated with sudden death in young athletes. On long-termfollow up, syncope, chest pain and dyspnea are well known frequent symptoms due to the dynamic left ventricularoutflow tract (LVOT) obstruction, mitral regurgitation and diastolic dysfunction. To reduce the LVOT pressuregradient, septal myectomy and alcohol injection have recently been utilized. However, some complications havebeen reported with alcohol ablation of the septal branches, such as complete atrioventricular block and alcoholspill over to ablate the entire left anterior descending coronary artery. Herein, a case of coil embolization of theseptal branches, with successful reduction of the LVOT pressure gradient, is reported in a patient with HOCM. KCI Citation Count: 0
