[Balloon rupture and alcohol leakage into the left anterior descending coronary artery during percutaneous septal ablation for hypertrophic obstructive cardiomyopathy]. / Rotura de balón y extravasación de alcohol hacia la arteria descendente anterior durante la ablación septal en paciente con miocardiopatía hipertrófica obstructiva.

We present a case of rupture of the balloon during percutaneous transluminal septal myocardial ablation with alcohol in a patient with hypertrophic obstructive cardiomyopathy. Rupture of the balloon caused reflux of alcohol into the left anterior descending artery. Angina, mild global hypokinesia of the left ventricle and advanced atrioventricular block were observed. Cardiac function recovered in a few minutes and peak creatine kinase was 526 U. Despite the restoration of sinus rhythm, there were episodes of complete atrioventricular block that made permanent pacemaker implantation necessary.

Presentamos un caso de rotura del balón de oclusión septal durante el procedimiento de ablación con alcohol en un paciente con miocardiopatía hipertrófica obstructiva. La rotura causó reflujo de alcohol a la arteria descendente anterior y originó angina, leve hipocinesia global, transitoria de ventrículo izquierdo y bloqueo auriculoventricular avanzado. La función contráctil se recuperó en pocos minutos y el pico de creatincinasa fue de 526 U. A pesar de restaurarse el ritmo sinusal, hubo episodios de bloqueo auriculoventricular que obligaron al implante de marcapasos definitivo
