Angioscopic evaluation of prolonged vs standard balloon inflations during coronary angioplasty

To study the immediate effects of prolonged total balloon inflation during PTCA, 41 patients (44 lesions) with chronic-stable angina were randomized for prolonged sequential inflations (three to five inflations of 3 to 5 min each, for a total duration of ≥ 12 min, group 1, n= θ20 lesions) or ‘standa...

Description
Summary:To study the immediate effects of prolonged total balloon inflation during PTCA, 41 patients (44 lesions) with chronic-stable angina were randomized for prolonged sequential inflations (three to five inflations of 3 to 5 min each, for a total duration of ≥ 12 min, group 1, n= θ20 lesions) or ‘standard’ sequential inflations (three to five inflations of ≤1 min each, for a total duration of ≤3 min, group 2, n-24 lesions). The mean duration of total balloon inflation time was 958 ± 129 s in group 1 vs 205 ±46 s in group 2. Results of angioplasty were assessed on both angiography and percutaneous transluminal coronary angioscopy performed immediately after the procedure. High quality imaging of the coronary lumen and lesion morphology was possible on angioscopy in all patients without any complications. Post-PTCA angiographic percent diameter stenosis was significantly less in group 1 compared to group 2: 26 ± 10% vs 36 ± 8% (P
