Abstract

This study was performed (1) to assess the incidence and magnitude of elastic recoil occurring within 15 minutes of successful coronary angioplasty, and (2) to determine the effect of subsequent additional balloon inflations on coronary luminal diameter in patients displaying substantial recoil. The coronary angiograms of 50 consecutive patients who underwent a successful percutaneous transluminal coronary angioplasty were analyzed using computer-assisted quantitative analysis. The patients were divided into 2 groups based on the magnitude of early elastic recoil following angioplasty: those with ≤10% (group I, n = 30) and those with >10% (group II, n = 20) loss of minimal luminal diameter as assessed by comparing the angiogram obtained immediately after successful angioplasty with that obtained 15 minutes later. The 2 groups were similar in clinical, angiographic, and procedural characteristics. Of the 20 group II subjects, 18 (90%) underwent repeat balloon dilatations, and 2 patients (10%) had no further intervention. After additional balloon inflations were performed in these 18 patients, 16 (90%) had a final result with <10% loss of minimal luminal diameter 15 minutes later. In conclusion, elastic recoil 15 minutes after apparently successful percutaneous transluminal coronary angioplasty is frequent, occurring in approximately 40% of patients, and is attenuated in 90% of subjects with additional balloon inflations. The resultant larger lumen diameter may exert a salutary effect on long-term outcome.
