Transthoracic device closure of ventricular septal defect for infants weighting less than 10 kilograms
Abstract：Objective To summarize the clinical experience of transthoracic closure of ventricular septal defect (VSD)in infants and young children weighting less than 10 kg. Methods Following the guidance of trans-esophageal echocardiography,a small inferior median incision (1.5 cm)was made in the sternum. Then the peri-cardium was opened and suspended to expose the free wall of right ventricular. A puncture site on the free wall of right ventricular was determined,through which a floppy guidewire was inserted. The delivery sheaths and sym-metric VSD device were introduced over the guidewire into the right ventricular cavity. Results The transthoracic device closure of VSD was employed successfully in all the patients,without causing any death or complete atri-oventricular block. Moreover,the transthoracic device closure of VSD showed advantages over the open heart septal defect repair with cardiopulmonary bypass,and significant differences (P<0.05)exist in terms of operation time [(75.5±14.1)min vs(136.0±31.4)min],postoperative mechanical ventilation time[(270.1±88.9)min vs(773.8± 515.4)min],operation drainage,follow-up period of hospitalization [(9.2±2.2)d vs (10.9±3.0)d],and transfu-sion volume [(61.5±19.7)ml vs (110.6±36.0)ml]. Conclusion Using domestically made device under transtho-racic echocardiographic guidance,the transthoracic device closure of VSD with an inferior sternotomy is a safe, feasible,and simple treatment,particularly for infants and young children weighting less than 10 kg.
