PP-167 Transient Left Ventricular Systolic Disfunction Occured after Percutaneous Transcatheter Closure of Large Pdas: A Report of Three Cases




Introduction


Isolated patent ductus arteriosus (PDA) that is not being a part of a complex congenitally heart disease leads to a dilatation on left heart structures according to amount of left to right shunting. Transcatheter occlusion of large PDAs has been more preferable technique compared with a surgical ligation because of satisfactory results of occlusion and low rates of complication. However, device embolisation, residual shunts, stenosis of the left pulmonary artery, coarctation of aorta and infective endocarditis takes place among the well known complications releated the procedure. We want to emphasize being a less known complication that is transient left ventricular systolic disfunction.




Cases


Case1: A fourteen years old girl who admitted to our hospital because of a continuous-murmur with a PDA suspicion. Echocardiography showed a large PDA and left heart dilatation. Upon a large PDA detection, a transcatheter occlusion was performed by a device of 12×10 mm Amplatzer Duct Occluder-I (ADO-I). There wasn’t any complication during the procedure but LVEF was observed as %52 after the day. She hadn’t any coronary symptom. The ECG and cardiac markers were found normally. Captopril was started. In follow-up LVEF was rising and found %55 a month after the procedure.


Case2: A 3 years girl with a continuous-murmur whom echocardiogram was showing a large PDA was hospitalised. PDA was closed by 5×6 mm ADO-II device. Although there was no complication, LVEF was observed as %48 after a day. Her ECG and cardiac markers were found normally. LVEF was observed %65 after a week. We couldn’t find any other cause.


Case3: A 6 months male baby who wasn’t able to weight gain, suffered from feeding-difficulty, respiratory distress and had a murmur. On transthorasic echocardiorgaphy, he had a large PDA measured 5 mm and the left sided heart enlargement was observed. Then, transcatheter PDA closure was performed by 6×7 mm ADO-I device. Although there was no complication, LVEF was found %44 after a day and %60 after a week. The ECG and cardiac enzymes were found normally.
