Abstract

The Lifetech Multifunctional occluder is a versatile device with an improved delivery and flexibility that reduces the risk of atrioventricular block. This is a retrospective, descriptive, pilot study done in 25 patients who underwent transcatheter closure of ventricular septal defect using Lifetech Multifunctional occluder from February 2017 to January 2018.

The average age was 9.32 ± 7.20 years, with a range from 1 to 32 years. Procedural success was 100% with no case needing a change of device size. Closure rate on follow up was at 42% (10/24), 52% (12/23), and 81% (17/21) at 1 day, 1 month, and 6 months, respectively. At 6-month follow up, pre-procedure tricuspid regurgitation disappeared by 38%. However, the incidence of new onset tricuspid regurgitation to trace was 16% (2) and mild 8% (1). Pre-procedure mild aortic regurgitation remained the same status throughout the 6-month follow up. Closure of the defect did not improve or worsen the aortic regurgitation. Post-transcatheter closure of ventricular septal defect with mild infundibular hypertrophy, the 1-year-old patient had resolution of the infundibular hypertrophy after 6 months but our 9-year-old patient had persistence of the mild infundibular hypertrophy even after 6 months. One patient (4%) developed transient widened QRS complexes post-transcatheter closure that resolved after 1 month. In total, 92% of the patients had no periprocedural complications. While one patient each had an inadvertent urinary bladder puncture and device embolisation.

Our retrospective review of the procedural and short-term outcomes of transcatheter closure of ventricular septal defect sizes 2–10 mm, using the Lifetech Multifunctional occluder, appears to be safe and effective. However, long-term follow up is warranted.
