Left ventricular systolic dysfunction following percutaneous closure of patent ductus arteriosus: A case series

Abstract

Transcatheter closure has become the standard treatment for patent ductus arteriosus (PDA) with excellent short- and long-term results. Left ventricular systolic dysfunction after closure is a known phenomenon rather than a complication with varied incidence documented in literature. Here, we report our experience of six cases who developed left ventricle (LV) dysfunction following percutaneous closure of PDA. Age, PDA size indexed to body surface area and pulmonary hypertension were the parameters noted to be associated with poorer LV function after closure. The LV dysfunction was transient and asymptomatic in most with delayed recovery noted with increasing age.
