Insights
Percutaneous coronary intervention (PCI) can effectively revascularize patients with left main coronary artery disease and severely depressed left ventricular ejection fraction (LVEF). This approach led to improved LVEF and reduced ventricular size in a patient with dilated cardiomyopathy.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
Background:
- Surgical revascularization improves survival and left ventricular ejection fraction (LVEF) in patients with left main coronary artery disease (CAD) and ventricular dysfunction.
- Percutaneous coronary intervention (PCI) is a viable alternative to surgery for multivessel and unprotected left main CAD.
Observation:
- Outcomes of unprotected left main PCI in patients with severely depressed LVEF remain under-examined.
- A case of left main chronic total occlusion, multivessel CAD, and dilated cardiomyopathy is presented.
Findings:
- Complete revascularization achieved through PCI in this patient.
- Successful PCI resulted in decreased left ventricular size.
- Significant improvement in left ventricular ejection fraction (LVEF) was observed post-PCI.
Implications:
- PCI may be a safe and effective strategy for unprotected left main CAD in patients with severely impaired LVEF.
- This case highlights the potential for PCI to improve cardiac function in complex CAD patients.
- Further research is warranted to confirm these findings in larger cohorts.
Abstract:
Surgical revascularization of left main and/or three-vessel coronary artery disease (CAD) is associated with improved survival in patients with left ventricular dysfunction when compared to medical therapy and can result in improved left ventricular ejection fraction (LVEF) [1]. Multivessel percutaneous coronary intervention (PCI) is equivalent to surgery regarding short and intermediate term mortality, and left main PCI has emerged as a safe and effective alternate to surgical revascularization [2]. However, outcomes of unprotected left main PCI in patients with severely depressed LVEF have not been examined. We report a patient with left main chronic total occlusion, multivessel CAD, and dilated cardiomyopathy, in whom complete revascularization via PCI resulted in decreased left ventricular size and improved LVEF.
