Abstract

INTRODUCTION

Ventricular septal defect is the most common congenital heart defect. The prevalence of postoperative pulmoner arterial hypertension in patients, who underwent ventricular septal defect closure, is not clear to the delayed cases. The aim of this study was to analyse the prevalence of pulmoner arterial hypertension after ventricular septal defect closure at the patient population who were older than one year old.

METHODS

Between June 2019, and March 2020, 36 patients underwent ventricular septal defect repair at a median a.ge of 2 years (1-19 years) and a median weight of 10 kg (5.5 -53kg). The following Ventricular Septal Defect types were found: 20 perimembranous (55%), 10 outlet (27%), 5 inlet (13,9%), and 1 trabecular (2,8%). Pulmoner arterial hypertension was defined as mean pulmonary arterial pressure of ≥25 mm Hg.

RESULTS

There was no postoperative complications and mortality. No patient underwent reop- eration for a residual Ventricular Septal Defect. Median systolic pulmoner artery pressure was 30mmHg (20-80mmHg) at early postoperative period. 4 patients were discharged on pulmonary vasodilatator agents. All patients were hemodynamically stable during 7.8±3.8 month follow-up

DISCUSSION AND CONCLUSION

Ventricular septal defect surgical closure is a safe procedure with very low morbidity and mortality rates. Pulmoner arterial hypertension is well tolarated with the help of the pulmonary vasodilator treatment at the early postoperative period.
