Percutaneous closure of postoperative and post-traumatic ventricular septal deffects

ABSTRACT

Although uncommon, significant postoperative residual leaks may occur after repair of any type of a ventricular septal deffect (VSD). Post-traumatics VSDs are even rarer, but can be occasionally seen after penetrating or blunt chest trauma. When these defects are associated with significant left-to-rigth shunting (Qp/Qs > 1.5) with persistent left ventricular volume overload, intervention is generally recomended. Surgical treatment requires cardiopulmonary bypass with its attendent morbidity, increased hospital stay and possible long-term neurological impairment. With the envolving experience of transcatheter closure of postinfarction and native perimembranous and muscular VSDs, this less invasive method became an attractive alternative to manage these postoperative and post-traumatic deffects...
