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 off-
pump CABG and group B (30) patients had on-pump CABG. All
patients were subjected to pre-operative, early post-operative
and sixmonths followup, 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 pre-
operative, 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 post-
operative in bothmodalities of CABG irrespective of the surgical
technique and completely improved to normal after sixmonths.
Both surgical techniques produced equivalent results on the RV
function with or without significant disease of RCA.
