Preoperative SPECT Results in Patients Who Had an Occluded Conduit to PDA
Both the rest and stress SPECT tests were performed preoperatively in 22 of 30 patients who showed an occluded SV conduit to the posterior descending coronary artery (PDA) on early postoperative angiograms (group R, n=5; group O, n=17). The reversibility score of PDA territory was lower in group R than in group O, but with no statistical significance (9.4±13.1 versus 22.8±16.5;P =0.115).
