Coronary angioplasty of 'complex lesions' in patients with unstable angina
Insights
Coronary angioplasty successfully treated complex coronary lesions in 22 unstable angina patients. This procedure demonstrated high success rates with minimal complications, offering a viable treatment option.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Unstable angina is a significant concern in cardiovascular disease.
- Complex coronary lesions pose challenges for percutaneous coronary intervention.
- Identifying effective treatments for complex lesions is crucial.
Purpose of the Study:
- To evaluate the efficacy and safety of coronary angioplasty for complex coronary lesions in patients with unstable angina.
- To analyze the success rates and complication profiles of the procedure in this specific patient group.
Main Methods:
- Retrospective analysis of 22 patients with unstable angina and complex coronary lesions.
- Coronary angiography to classify lesion complexity.
- Percutaneous coronary angioplasty (coronary angioplasty) performed on 35 lesions.
- Assessment of angiographic success and complications.
Main Results:
- Angiographic primary success rate of 85.7% for attempted lesions.
- High success rates (>75%) for most complex lesion types, excluding total occlusions and very distal lesions.
- Low complication rate, with one non-Q wave infarction and no deaths.
Conclusions:
- Coronary angioplasty is effective for treating various complex coronary lesions in unstable angina patients.
- The procedure offers good primary success with negligible complications in this setting.
- Further research may explore strategies for challenging lesions like total occlusions.
Abstract:
Out of 55 patients subjected to coronary angioplasty over the past 12 months, there were 33 (60%) who had unstable angina. Amongst these, 22 patients had coronary lesions classified as 'complex' on coronary angiography. These included tandem lesions, branch stenoses, distal lesions, total occlusions, vein graft stenoses, lesions with ulceration and intraluminal clot and associated with valvular lesions. We describe our experience of coronary angioplasty in these 22 patients of unstable angina having 'complex lesions'. All were males with a mean age of 48.7 +/- 13 years. Fourteen patients had single vessel and 8 multivessel disease. A total of 35 lesions were subjected to dilatation. The angiographic primary success was achieved in 85.7% of the lesions attempted. Except total occlusions and very distal lesions, all other types of 'complex lesions' could be dilated with a success rate of greater than 75%. There were 4 (11.4%) failures because of inability to cross the lesion with the guidewire or balloon catheter. One patient developed non-Q wave inferior wall infarction. There were no deaths. We conclude that coronary angioplasty of various types of 'complex lesions' can be performed with a good primary success and negligible complications in our setting.
