Dr Alexandre M de Oliveira on Instagram: "Multiple muscular Ventricular Septal Defects (VSDs) are defined as the presence of more than one VSD in the muscular septum, with or without other VSD located in the peri-membranous or outlet septum, with or without associated intra-cardiac or extra-cardiac malformations. The surgical closure of multiple muscular VSDs remains a technically difficult procedure, due to inadequate exposure of the defects, with or without a right or left ventriculotomy. #fet
