Why the study?

Does preoperative MSCT accurately identify graft patency, anatomical course, and plaque composition compared to conventional catheter angiography in patients undergoing redo cardiac surgery?

Population

40 patients with previous CABG and a total of 104 grafts referred for reoperative cardiac surgery

Comparison

Preoperative ECG-gated multislice CT imaging vs Conventional catheter angiography (CA)

Implication

May aid redo surgery planning via accurate graft assessment; leaves open prospective validation before routine use.

Structured PICO

Does preoperative MSCT accurately identify graft patency, anatomical course, and plaque composition compared to conventional catheter angiography in patients undergoing redo cardiac surgery?

P
Population
40 patients with previous CABG and a total of 104 grafts referred for reoperative cardiac surgery
I
Intervention
Preoperative ECG-gated multislice CT (MSCT) imaging (16-detector row scanner, 0.75mm slice thickness)
C
Comparator
Conventional catheter angiography (CA)
O
Outcome
Identification of graft patency, anatomical course of coronary bypass grafts, and plaque compositionsurrogate

Preoperative MSCT is a highly accurate non-invasive imaging modality for evaluating bypass graft patency, anatomical course, and plaque composition to aid in planning redo cardiac surgery.
