Objectives: To identify the clinical characteristics, analyze the results and show the efficacy of surgical treatment of hypertrophic obstructive cardiomyopathy (HOC), in a national reference institute. Methods: A descriptive, retrospective, case series of patients with the diagnosis of HOC operated at the National Cardiovascular Institute, was performed between December 2016 and January 2019. We analyzed the postoperative evolution of symptomatology, functional class (FC), left ventricular outflow tract gradient (LVOTG) and mitral regurgitation (MR). Results: Thirteen cases with HOC undergoing extended septal myectomy were evaluated. 31% were women and the average age was 39.6 years. Before surgical treatment, 85% were in functional class (FC) III-IV, 85% of patients had severe MR, the mean septum thickness was 27 mm (range from 19 to 39 mm), and mean LVOTG was 111 mmHg (range from 60 t...

Objetivos: Identificar las características clínicas, analizar los resultados y mostrar la eficacia del tratamiento quirúrgico de la miocardiopatía hipertrófica obstructiva (MHO), en un hospital de referencia nacional. Material y método: Se realizó un estudio descriptivo, retrospectivo, tipo serie de casos, de pacientes operados en el Instituto Nacional Cardiovascular con el diagnóstico de MHO, entre diciembre del 2016 y enero del 2019. Se analizó la evolución posoperatoria de la sintomatología, clase funcional (CF), gradiente del tracto de salida del ventrículo izquierdo (GTSVI) y de la insuficiencia mitral (IM). Resultados: Se evaluaron 13 casos con MHO sometidos a miectomía septal extendida. Un 31% fueron mujeres y la edad media fue de 39.6 años. Antes del tratamiento quirúrgico 85% se encontraba en CF III-IV, 85% de pacientes presentaba IM severa, el grosor medio del se...
