Percutaneous transluminal angioplasty of coronary arteries with anomalous origin
1Cardiology Division, Soroka Medical Center, Beer Sheva, Israel.
Insights
Percutaneous coronary angioplasty (PTCA) is increasingly used for anomalous coronary arteries. Success rates and complications require further study, emphasizing the need for precise angiographic knowledge.
Area of Science:
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Anomalous coronary arteries are increasingly treated with percutaneous coronary angioplasty (PTCA).
- Limited data exists on the success rates and complications of PTCA in these specific anatomical variations compared to normally originating arteries.
Purpose of the Study:
- To highlight the growing application of angioplasty in anomalous coronary arteries.
- To underscore the need for more reported cases to establish success rates and complication profiles.
Main Methods:
- Review of existing literature on PTCA for coronary anomalies.
- Discussion of potential alternative techniques like laser atherectomy and stenting in tortuous anomalous vessels.
Main Results:
- Several successful angioplasty cases in coronary anomalies have been reported.
- Many PTCA attempts in anomalous coronary arteries may go unreported, skewing outcome data.
- Other interventional techniques may be applicable depending on vessel tortuosity.
Conclusions:
- Angioplasty for anomalous coronary arteries is feasible but requires careful consideration.
- Accurate angiographic understanding of the anomalous coronary course is crucial for procedural success.
- Further reporting is needed to define optimal strategies and outcomes for revascularizing anomalous coronary arteries.
Abstract:
Coronary angioplasty to diseased anomalous coronary arteries is being more readily applied in revascularization of these vessels. Several cases of angioplasty have been described in various coronary anomalies. Probably more attempts of PTCA to anomalous coronary arteries are performed but not reported. For this reason, we cannot assume that the success rate is the same as in "normal" origin arteries or which complications occurred, including the need for coronary bypass. Although not yet reported, in some instances other techniques, such as laser atherectomy and coronary stents, may be applied, provided the artery is not tortuous, as it may be in some anomalous coronaries. The key to a successful procedure depends on angiographic knowledge of their course and appropriate equipment selection.
