Abstract :

Aim

To assess and compare del Nido versus St. Thomas cardioplegia during aortic valve replacement surgery. Variables assed include cross–clamp time, cardiopulmonary bypass (CPB) time, time required from cross–clamp removal to weaning/separation from CPB and post cross clamp defiillation/cardioversion requirement between two groups

Methods and Materials

Patients admitted in between the period of January 2015 to June 2018 for isolated aortic valve replacement surgery were included in this retrospective study. Patients were divided into two groups each comprising of 30 patients, according to type of cardioplegia received during surgery.

Results

The aortic cross–clamp, CPB time, time required to wean from CPB were shorter with del Nido cardioplegia (77.1 ± 12.97 vs 84.2 ± 14; 107.3 ± 16.5 vs 120.2 ± 16.8; and 30.2 ± 5.1 vs 36.4 ± 8.9 minutes, respectively). The post cross–clamp removal defiillation requirement was also less with del Nido cardioplegia (13% vs 36%).

Conclusion

The use of Del Nido cardioplegia has shown to decrease cross–clamp time, CPB time, time from cross–clamp removal to wean from CPB and the requirement of defiillation post cross–clamp removal.
