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).
