Insights
On-pump beating-heart surgery using warm blood perfusion is a safe and effective cardiac surgery technique. This study of 701 patients demonstrates its reliability for treating various cardiac diseases.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Thoracic Surgery
Background:
- Beating-heart surgery with warm blood perfusion is a recognized cardiac operation technique.
- Limited large-scale studies evaluate the efficacy and safety of on-pump beating-heart surgery.
- This study assesses the safety and efficacy of on-pump beating-heart surgery in a significant patient cohort.
Purpose of the Study:
- To evaluate the efficacy and safety of on-pump beating-heart surgery.
- To analyze outcomes in patients undergoing cardiac surgery with warm blood perfusion.
- To assess the feasibility of beating-heart surgery in a large patient group.
Main Methods:
- A retrospective analysis of 701 consecutive cardiac surgery patients from January 2002 to December 2006.
- Documentation of preoperative risk factors, intraoperative techniques, and postoperative complications.
- Evaluation of patients undergoing on-pump beating-heart surgery with continuous antegrade or retrograde warm blood perfusion.
Main Results:
- Antegrade perfusion was utilized in 79.32% of patients, retrograde in 5.71%, and combined in 13.27%.
- Cardioplegic arrest was needed in only 1.71% of cases for visualization.
- Low cardiac output syndrome occurred in 0.57%, hemoglobinuria in 2.28%, with no air embolization or permanent high-degree AV block. Crude mortality was 2.43%.
Conclusions:
- On-pump beating-heart surgery with warm blood perfusion is a relatively safe and reliable method.
- The technique demonstrates acceptable safety and efficacy for treating cardiac diseases.
- This large-scale study supports the use of beating-heart surgery in cardiac operations.
Background:
Beating-heart surgery with warm blood perfusion, instead of cardioplegic solution, has been widely accredited to be a feasible technique in the cardiac operation. However, few studies have addressed the efficacy and safety of on-pump beating-heart surgery, especially with large numbers of patients. In this study, the efficacy and safety of on-pump beating-heart surgery was evaluated by surveying 701 patients with cardiac disease.
Methods:
Preoperative risk factors, intraoperative techniques, and postoperative complications were documented and evaluated in 701 consecutive patients (from January 1, 2002, to December 30, 2006) who underwent beating-heart surgery with continuous antegrade or retrograde warm blood perfusion at The People's Hospital of Guangxi Zhuang Autonomous Region.
Results:
Among the 701 patients with beating-heart surgery, antegrade perfusion was used in 556 patients (79.32%); retrograde perfusion was used in 40 patients (5.71%); and retrograde perfusion followed by antegrade perfusion was performed in 93 patients (13.27%). Cardioplegic arrest was required in 12 patients (1.71%) for inadequate visualization. In 4 of 701 patients (0.57%) low cardiac output syndrome occurred. Hemoglobinuria occurred in 16 patients (2.28%). No air embolization or permanent high-degree atrioventricular block occurred in these patients. The crude mortality of the surveyed patients was 2.43% (17 of 701).
Conclusions:
Our results indicate that on-pump beating-heart surgery is a relatively safe and reliable technique for treatment of cardiac diseases.
