TL;DR: The results of follow-up angiography in patients from 27 clinical centers enrolled in the PTCA Registry were analyzed and 4 factors associated with increased rate of restenosis were selected: male sex, P TCA of bypass graft stenosis, severity of angina before PTCa and no history of MI before PtcA.

TL;DR: The Percutaneous Transluminal Coronary Angioplasty Registry of the National Heart, Lung, and Blood Institute reopened at its previous sites to document changes in angioplastic strategy and outcome in August 1985 and the in-hospital outcome in the new cohort was better.

TL;DR: The incidence of coronary perforation using balloon angioplasty and new revascularization techniques and to develop optimal strategies for its management based on classification and outcome was determined.

TL;DR: Baseline patient factors independently associated with increased occlusion rates included triple-vessel disease, high risk status for surgery, and acute coronary insufficiency, while Lesion characteristics showing significant positive association included severe stenosis before PTCA, diffuse or multiple discrete morphology, thrombus, and collateral flow from the lesion.

TL;DR: The frequency of any coronary event, MI, prolonged angina and coronary spasm each decreased with increasing experience with PTCA, and the frequency of dissection and occlusion did not change with experience.
