The evolution of repeat coronary artery surgery.

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology

Background:

• The patient demographic undergoing surgical secondary revascularisation (RECABG) has shifted significantly over the past two decades.
• There is an increasing prevalence of older patients with more comorbidities presenting for RECABG.
• Changes in primary coronary artery bypass surgery (CABG) strategies, including arterial graft use and routine medical therapies, impact the RECABG population.

Purpose of the Study:

• To review the evolutionary trends in the patient population undergoing secondary revascularisation.
• To analyze demographic and clinical changes in patients requiring repeat revascularisation procedures.

Main Methods:

• Literature review and analysis of trends in secondary revascularisation patient populations.
• Examination of data related to changes in CABG strategies and their impact on RECABG.

Main Results:

• The patient profile for RECABG has changed, characterized by an aging population and increased comorbidities.
• Widespread use of arterial grafts in CABG extends the event-free period but presents challenges for RECABG, especially with patent grafts.
• Advancements in percutaneous coronary intervention (PCI) influence the management and presentation of patients for secondary revascularisation.

Conclusions:

• Understanding these evolutionary trends is crucial for optimizing surgical secondary revascularisation strategies.
• The changing landscape of CABG and PCI necessitates adaptive approaches to secondary revascularisation.
• Future research should focus on managing complex RECABG cases in the evolving patient population.
