[Short- and mid-term outcomes of arrhythmia after transcatheter and surgical closure of membranous ventricular septal defects: a comparative analysis].

Objective: To evaluate the short- and mid-term outcomes of arrhythmia in patients undergoing transcatheter and surgical closure of membraneous ventricular septal defect (VSD).

Methods: 358 VSD patients, 161 male and 197 female, aged (11 +/- 8), underwent transcatheter closure and 50 sex, age, body weight, size of membranous VSD, and percentage of complicated membranous aneurysm-matched VSD patients underwent surgical closure. Electrocardiography was conducted 1, 3, 6, and 12 months after VSD closure.

[Risk factors for early arrhythmias post transcatheter closure of perimembranous ventricular septal defects].

Objective: To analyze the risk factors for early arrhythmias after transcatheter closure of perimembranous ventricular septal defect (PVSD).

Methods: A total of 358 patients [161 males, aged from 3 to 54, mean (10.9 +/- 8.

[Radiofrequency perforation and balloon valvuloplasty in infants with pulmonary atresia and intact ventricular septum].

Objective: To investigate the efficacy and safety of percutaneous radiofrequency perforation and valvuloplasty in infants with pulmonary atresia with intact ventricular septum (PA/IVS).

Methods: Four infants (body weight 4 - 10 kg) aged 11 months, 9 months, 12 days and 9 months old, respectively, were hospitalized for dyspnea and cyanosis. All patients had a continuous murmur in the left second intercostal space.

[Transcatheter closure of atrial septal defects in 40 pediatric patients].

Objective: To evaluate the clinical efficiency of transcatheter closure of atrial septal defect (ASD) with AGA-Amplatzer occlusion device in pediatric patients.

Methods: Forty patients with ASD, 16 males, 24 females, at a mean age of 10.2 years (ranged from 3 to 15 years of age) and with a mean weight of 35.
