Septal Myectomy in Recurrent Subaortic Membrane

Abstract

Mujer de 54 anos de edad, con antecedentes de insuficiencia cardiaca congestiva y reseccion quirurgica de membrana subaortica (MSA) en los anos 1984 y 2001, que reingreso en nuestro centro por disnea. Se realizo una ecocardiografia transtoracica, que evidencio estenosis subaortica severa con gradiente medio transvalvular de 42 mmHg, reaparicion de la MSA, protrusion del septo interventricular (que dejaba 0,8 cm en el tracto de salida del ventriculo izquierdo [TSVI]), que se confirmo por tomografia computarizada (fig. 1A, asterisco), ademas de insuficiencia aortica severa. Se decidio intervencion quirurgica de membranectomia, miomectomia septal y sustitucion valvular aortica. En el quirofano se objetivo una MSA fibrosa densa que obstruia el TSVI a 14 mm del origen de la valvula aortica. La MSA se extrajo del TSVI facilmente, tras acceder a ella mediante esternotomia media y aortotomia transversa. Se realizo miomectomia septal concomitante, y se extraeron 15 ml de la pared interventricular (fig. 1B), ademas de implantar una valvula mecanica de 19 mm Bicarbon Slimline (Sorin Group, Saluggia, Italia), con lo que se consiguio incrementar el TSVI de 10 a 22 mm (confirmado mediante ecocardiografia transesofagica; fig. 1C) en 66 min de pinzamiento aortico. La paciente fue dada de alta sin complicaciones a los 13 dias. A los 6 meses permanecia asintomatica, con un gradiente medio transaortico de 8 mmHg. La reseccion transaortica de una MSA es un tratamiento aceptable, pero asociado a una alta incidencia de recurrencias que requieren reintervencion (6-30%), por lo que es razonable considerar tecnicas alternativas como la miomectomia septal, ya que se ha asociado a menor frecuencia de recurrencia (hasta un 4%), sobre todo en reintervenciones cardiacas.
