First worldwide use of the hybrid system for extracorporeal circulation in heart transplant.

ABSTRACT

BACKGROUND: This case report documents the first worldwide use of the Hybrid System from Spectrum Medical in a heart transplant procedure, focusing on its safety and efficacy. Traditional cardiopulmonary bypass systems often use an open reservoir, which increases the blood's exposure to air, thereby heightening the risk of an inflammatory response and gas embolism. In contrast, the Hybrid System is designed to improve surgical outcomes by significantly reducing the blood-air interface. This system utilizes a dual-chamber cardiotomy-venous reservoir with a collapsible soft bag, effectively minimizing blood contact with air and foreign materials. However, it is important to note that there is currently no evidence supporting the use of this methodology specifically in heart transplants. CASE PRESENTATION A 41-year-old male managed with a left ventricular assist device because of dilated cardiomyopathy underwent a heart transplant using the Hybrid System. The perioperative and postoperative data provided evidence of the system's effectiveness. The selection of this patient was due to the absence of significant comorbidities unrelated to his primary cardiac condition, making him an ideal candidate to evaluate the system's performance. CONCLUSION: The Hybrid System is safe and efficient. The successful implementation in this case highlights its advantages over traditional cardiopulmonary bypass systems, suggesting a promising future in cardiac surgery. Further studies with routine cardiac surgery patients are required to validate these findings.
