Abstract:
Background: The right ventricle (RV) may be selectively impaired following coronary artery bypass graft (CABG). Methods: We tested this hypothesis by prospective study. We examined two groups of patients. Group A (30) patients had offpump CABG and group B (30) patients had on-pump CABG. All patients were subjected to pre-operative, early post-operative and six months follow up, full clinical and ECHO-Doppler studies. All patients had preoperative diagnostic coronary angiography (CA). Results: There was insignificant difference comparing the clinical picture of right side heart failure (RSHF) in both groups. Pre-operative characteristics and RV function by ECHO did not differ significantly between the two groups (mean±SD): tricuspid annular plane systolic excursion (TAPSE) was 1.83±0.7 cm, 1.47±0.51 cm and 1.87±0.34 cm in pre-operative, early post-operative and six months follow up respectively in group A (off-pump patients), while in group B (on-pump patients) was 1.99±0.65 cm, 1.63±0.49 cm and 1.97±0.41 cm in preoperative, early post-operative and six months follow up respectively. The tricuspid annulus pulsed wave tissue Doppler (TDTA) was 11.98±3.0 cm/sec, 9.77±1.73 cm/sec and 11.9±1.72 cm/sec in pre-operative, early post-operative and six months follow up in group A, while in group B it was 12.83±3.0 cm/sec, 10.77±2.12 cm/sec and 12.27±1.68 cm/sec. The parameters of RV function including PASP, RV dimension; TAPSE and TDTA were significantly impaired early post-operative in both groups and completely improved after six months. Conclusion: The RV function significantly impaired early postoperative in both modalities of CABG irrespective of the surgical technique and completely improved to normal after six months. Both surgical techniques produced equivalent results on the RV function with or without significant disease of RCA.
