Abstract

ResumenObjetivoMostrar la eficacia, seguridad y reproducibilidad de la técnica de Konno modificada en la resolución de la miocardiopatía hipertrófica obstructiva.MétodosCuatro casos de miocardiopatía hipertrófica obstructiva, con edades de 8–59 años, 3 mujeres y 1 varón, clínica de angina, disnea y presíncopes. Gradiente máximo de 65–120 mmHg. Todos presentaban movimiento sistólico anterior de la válvula mitral e insuficiencia mitral, y fueron intervenidos con técnica de Konno modificada.ResultadosTodos sobrevivieron. El gradiente preoperatorio descendió un 91%. Tres casos quedaron con insuficiencia mitral ligera, todos pasaron a grado funcional I. Única complicación: necesidad de marcapasos definitivo en un caso. Seguimiento medio de 54 meses.ConclusionesEsta técnica cambia la resección septal de Morrow por la ampliación del tracto de salida del ventrículo izquierdo. Se ha mostrado eficaz y segura, con resultados estables.

BackgroundThe efficacy, safety and feasibility of the modified Konno procedure for the surgical correction of hypertrophic obstructive cardiomyopathy (HOCM) are demonstrated.MethodsFour patients underwent a modified Konno procedure. The ages ranged from 8 to 59 years. There were three females and one male. Symptoms referred to were angina, dyspnea and presyncope. The echocardiography study revealed a maximum gradient between 65–120 mm Hg. Systolic anterior motion of mitral valve and mitral regurgitation was present in all cases.ResultsThere were no in-hospital deaths. The gradients decreased by 91%. Mild postoperative mitral regurgitation was present in three patients. One permanent pacemaker was implanted. Mean follow up was 54 months.ConclusionsThis procedure is an alternative to the Morrows septal myectomy for the correction of HOCM, allowing a greater enlargement of the left ventricular outflow tract. It can be performed with good early and mid-term results proving to be safe and feasible.
