[Coronary endarterectomy: state of the art]
Insights
Coronary endarterectomy (EA) offers a way to treat inoperable coronary vessels. Despite controversy, EA is increasingly used, expanding options for myocardial revascularization in more patients.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
Context:
- Coronary endarterectomy (EA) is a controversial but increasingly utilized procedure for treating complex coronary artery disease.
- Advancements in surgical techniques have led to a growing interest in EA for myocardial revascularization.
Purpose:
- To analyze various individualized techniques of coronary EA, including local, conventional 'blind,' open with reconstruction, and laser EA.
- To evaluate the technical aspects, indications, and outcomes (operative risk, symptomatic improvement, graft patency) of different EA procedures.
Summary:
- EA enables recanalization and bypass of vessels previously considered inoperable.
- The study examines diverse EA techniques, assessing their feasibility and results based on current clinical experience.
- While associated with moderately higher mortality and perioperative infarction rates compared to standard bypass grafting, EA is presented as a valuable adjunct.
Impact:
- Coronary endarterectomy expands the indications for myocardial revascularization, allowing more patients with conventionally inoperable coronary disease to undergo surgical treatment.
- EA facilitates more complete revascularization, particularly in patients with diffuse coronary artery disease, improving treatment accessibility.
Abstract:
Coronary endarterectomy (EA) allows to recanalize and bypass what appear to be an otherwise inoperable vessel. Although the application of this procedure is still controversial, there is now an increasing tendency to use the EA more frequently and recent studies confirm this trend. A variety of individualized techniques of performing coronary EA (local EA, conventional "blind" EA, open EA with coronary reconstruction, laser EA) are analyzed. Technical aspects, indications and results (operative risk, symptomatic improvement, grafts patency) of each procedure are evaluated on the basis of the current experiences. Although hospital mortality and perioperative infarction rates are moderately higher than in routine grafting, it is stressed that EA is a valuable supplement to coronary artery bypass grafting extending the indications of myocardial revascularization: a) larger number of conventionally inoperable patients can benefit from the surgical treatment; b) more complete revascularizations are possible in patients with diffuse coronary disease.
