Background: This report presents updated data and mid-term follow-up information to a former study introducing the novel technique of percutaneous-perventricular device closure of doubly committed subarterial ventricular septal defect.
Methods: Thirty-eight patients were added to the former series. There are totally 54 patients who had isolated doubly committed subarterial ventricular septal defects underwent percutaneous-perventricular device closure. Closure outcomes and possible complications were measured in the hospital and during the 2.5 years follow-up.
Results: Closure was successful in 53 patients (98.1%). There was no mortality, residual shunt, new valve regurgitation or arrhythmia either perioperatively or during the entire follow-up period. Only one patient who developed pericardial effusion and tamponade in the former series. The mean hospital stay was 3.2±0.6 days (range, 3.0 to 6.0 days), one unsuccessful cases needed blood transfusion (1.9%).
Conclusions: The percutaneous-perventricular device closure of isolated doubly committed subarterial ventricular septal defects appeared to be efficacious. Close monitoring for bleeding is very necessary postoperatively especially in younger patients. This technique is generally safe in selected group of patients with acceptable mid-term outcomes.
