PTCA in patients with stable angina pectoris and multivessel disease: is incomplete revascularization acceptable?
1Thorax Center, University Hospital Rotterdam, The Netherlands.
Insights
Incomplete revascularization during coronary angioplasty for multivessel disease is safe and effective in select patients. Achieving adequate functional revascularization, not just complete anatomic revascularization, is key for optimal outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Multivessel disease (MVD) accounts for 40% of coronary angioplasty procedures.
- While angioplasty offers high immediate success in MVD, complete anatomic revascularization is often not achieved (32-59%).
- Incomplete revascularization raises concerns regarding patient outcomes.
Purpose of the Study:
- To review the literature on coronary angioplasty in patients with MVD.
- To assess the safety and efficacy of incomplete revascularization in selected MVD patients.
- To define criteria for adequate revascularization in MVD.
Main Methods:
- Literature review of studies on coronary angioplasty for multivessel disease.
- Analysis of immediate and long-term outcomes associated with complete versus incomplete revascularization.
- Evaluation of functional revascularization strategies.
Main Results:
- Coronary angioplasty in MVD patients demonstrates high immediate success and acceptable complication rates.
- Complete anatomic revascularization is achieved in a limited percentage of MVD patients.
- Incomplete revascularization can be safe and effective when adequate functional revascularization is attained.
Conclusions:
- Incomplete revascularization via coronary angioplasty is a viable strategy for selected MVD patients.
- Adequate functional revascularization, defined by addressing significant lesions supplying viable myocardium, is crucial.
- Focusing on functional revascularization can lead to favorable outcomes in MVD patients undergoing angioplasty.
Abstract:
Of all coronary angioplasties performed nowadays, 40% of the patients have multivessel disease. Angioplasty in patients with multivessel disease can be performed with a high immediate clinical success rate and an acceptable major complication rate. However, complete anatomic revascularization with coronary angioplasty is achieved in only 32 to 59%. This raises concern about the immediate and long-term outcome of patients in whom incomplete revascularization is achieved. This report reviews the literature and provides evidence that incomplete revascularization with coronary angioplasty is a safe and effective treatment in selected patients with multivessel disease, provided that adequate (functional) revascularization can be achieved. Adequate revascularization includes dilation of all significant lesions supplying large areas of viable myocardium.
