Insights
The hybrid off-pump method for ventricular septal defect (VSD) closure is safe and effective in children, offering shorter operation times and improved cosmetics compared to the traditional on-pump technique.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
Background:
- Isolated ventricular septal defect (VSD) is a common congenital heart anomaly.
- Surgical closure is the standard treatment for VSD.
- Traditional VSD closure utilizes an on-pump cardiopulmonary bypass method.
Purpose of the Study:
- To evaluate the safety and effectiveness of a hybrid off-pump method for VSD closure.
- To compare the hybrid off-pump method with the traditional on-pump method in pediatric patients.
Main Methods:
- Retrospective cohort study.
- Involved 500 pediatric patients with isolated VSD undergoing surgery between May 2016 and December 2020.
- Compared outcomes between the hybrid off-pump (n=250) and traditional on-pump (n=250) VSD closure methods.
Main Results:
- The hybrid off-pump method achieved a 93.2% procedural success rate with a 6.4% conversion rate.
- Mean operation time was significantly shorter for the hybrid group (84 minutes) versus the traditional group (168 minutes) (P=.000).
- Hospital mortality was lower in the hybrid group (0.43%) compared to the traditional group (1.5%) (P=.000).
Conclusions:
- The hybrid off-pump VSD closure is a safe and effective option for select pediatric patients.
- Advantages include improved cosmetic outcomes and reduced operation time.
- Shorter overall hospital stay is also a benefit of the hybrid approach.
Objective:
The aim of our study was to evaluate the safety and effectiveness of the hybrid method off-pump for closure of isolated ventricular septal defect (VSD) compared with the traditional method of on-pump of children.
Methods:
This research was a retrospective cohort study. Data were collected from 500 patients with isolated VSD (or residual VSD after a previous repair) who underwent surgery at the National Scientific Medical Center from May 2016 to December 2020. Patients were operated with 1 of 2 methods of surgery: the traditional method of on-pump or the hybrid method of off-pump. This study assessed the safety and efficacy of the hybrid method by comparing it with the traditional method for the treatment of patients with isolated VSD.
Results:
The procedural success rate reached 93.2% in the hybrid method, with a 6.4% conversion rate to the traditional method and 0.4% hospital mortality. The mean operation time was 84 minutes (31; 160 minutes) in the hybrid group (n = 250) and 168 minutes (70; 300 minutes) in the traditional group (n = 250) (P = .000). Hospital mortality was 0.43% in the first group and 1.5% in the second group (P = .000).
Conclusions:
The hybrid method of VSD closure is safe and effective in a selected group of patients. The advantages of the hybrid method are improved cosmetics and shorter operation time and overall hospital stay.
