Insights
Percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting increased in 1995, showing a 92% success rate with acceptable complication rates for transcatheter revascularization. These procedures are vital for treating various angina types.
Area of Science:
- Interventional Cardiology
- Cardiovascular Medicine
- Medical Device Technology
Background:
- Transcatheter revascularization procedures have seen significant growth.
- Understanding procedural volumes and outcomes is crucial for evaluating cardiovascular care advancements.
Purpose of the Study:
- To analyze the trends and outcomes of percutaneous transluminal coronary angioplasty (PTCA) and intracoronary stent placements in 1995.
- To assess the complication rates and success of these interventional cardiology procedures.
Main Methods:
- Retrospective analysis of 1108 PTCA procedures, 24 rotational atherectomies, and 109 intracoronary stent placements performed in 1995.
- Data collection on procedural indications, complications, and outcomes.
Main Results:
- A total of 1108 PTCA procedures were performed in 1995, a notable increase from 697 in 1994.
- Coronary stenting was performed in 109 patients (10% of procedures) with a 92% overall success rate for transcatheter revascularization.
- Complications included 6 acute myocardial infarctions, 10 emergency surgeries, and 11 deaths; stent-related complications were also documented.
Conclusions:
- Transcutaneous coronary revascularization, including stenting, has increased with acceptable success and complication rates.
- These interventional techniques are effective for patients with stable, unstable, and post-infarct angina.
Abstract:
In 1995, from 12 participating units, there were 1108 PTCA compared to 697 in 1994, 24 rotational atherectomy and 109 intracoronary stent placements performed. These were complicated by 6 acute myocardial infarction, 10 emergency surgeries and 11 deaths. Success rate was 92 per cent. Indication for transcatheter revascularization were stable angina pectoris in 60 per cent of cases, unstable angina in 18 per cent and post infarct angina in 16 per cent. Thirty cases were done in AMI setting. Of those 1108 vessels approached, 1297 lesions were in native arteries and 9 were in saphenous vein grafts. Most lesions were in AHA/ACC type B category. One hundred and fourteen stents were placed in 109 patients in 1995. Seven stents emboli occurred in addition to one myocardial infarction, 2 CABG, 2 death and 2 major bleeding. Transcutaneous coronary revascularization has increased in number with acceptable results. Coronary stenting was done in an average of 10 per cent of all procedures and also with reasonable complication rates.
