Comparison of perventricular and percutaneous ultrasound-guided device closure of perimembranous ventricular septal defects.

Background: Ultrasound-guided percutaneous device closure of perimembranous ventricular septal defects (PmVSD) is a minimally invasive recent treatment approach. Perventricular PmVSD device closure is an emerging radiation-free intervention, yet it comes with certain limitations. No studies compared both of these treatment approaches.

Transcatheter closure of atrial septal defect with deficient posterior-inferior or inferior vena cava rim under echocardiography only: a feasibility and safety analysis.

Background: The safe closure of atrial septal defect with deficient posterior-inferior or inferior vena cava rim is a controversial issue. Few studies have been conducted on the closure of atrial septal defect with deficient posterior-inferior or inferior vena cava rim without fluoroscopy. This study evaluated the feasibility and safety of echocardiography-guided transcatheter closure of atrial septal defect with deficient posterior-inferior or inferior vena cava rim.
