TRANSCATHETER DEVICE CLOSURE OF PERIMEMBRANOUS VENTRICULAR SEPTAL DEFECT FROM RIGHT VENTRICULAR APPROACH WITHOUT ARTERIO- VENOUS LOOP

Abstract

Objective: To evaluate the safety and efficacy of transcatheter closure for Perimembranous Vetrntricularseptal defect (pm VSD) without arteriovenous (AV) loop. The most common congenital heart defect is PMVSD. Trans-catheter closure of PMVSD without AV loop is a recently described technique with limited results for follow-up.

Study Design: Retrospective analytical study.

Place and Duration of Study: Paediatric Cardiology, Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi Pakistan, from Jan 2015 to Oct 2018.

Method and Methods: Total of 30 patients with PMVSD were enrolled in this retrospective analytical study and treated percutaneously with VSD occluders.

Results: All patients were followed up to date. According to colour Doppler transthoracic echocardiography the mean ± SD end-diastolic PMVSD size was 4.87 ± 1.32mm. Placement of the device was successful in all patients (100%) and the mean ± SD device size 7 ± 1.58mm. During follow-up, No major adverse events were reported.

Conclusions: In experienced hands, transcatheter PMVSD closure without AV loop can be performed safely and successfully with low morbidity and mortality. Short-term results are favorable, and the transcatheter approach provides a less-invasive alternative that may become the first choice in selected pmVSD patients.
