Combining PCI and CABG: the role of hybrid revascularization

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Interventional Cardiology

Background:

• Hybrid coronary revascularization (HCR) integrates percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG).
• It aims to leverage the durability of arterial grafts (LIMA-to-LAD) with the minimally invasive nature of PCI using drug-eluting stents (DES) for non-LAD targets.
• This strategy seeks to optimize outcomes for multivessel coronary artery disease (CAD) while reducing the morbidity associated with traditional CABG.

Purpose of the Study:

• To provide a comprehensive review of HCR in the context of contemporary DES technology.
• To discuss optimal patient selection criteria for HCR.
• To explore future directions for clinical trials in HCR.

Main Methods:

• Review of current literature on hybrid coronary revascularization.
• Analysis of outcomes data from existing small studies.
• Discussion of procedural techniques and technological advancements.

Main Results:

• Limited data exists, primarily from small studies, highlighting the need for larger trials.
• HCR potentially offers the benefits of LIMA grafts with reduced surgical invasiveness compared to full sternotomy CABG.
• The combination of LIMA-to-LAD grafting and DES to non-LAD territories is a key feature.

Conclusions:

• HCR represents a promising approach for select multivessel CAD patients.
• Further robust clinical trials are essential to define its long-term efficacy and safety.
• Patient selection and evolving DES technology are critical factors for successful HCR implementation.
