Practice differences and knowledge gaps in complex and high-risk interventions between Japan and the USA: A...

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Percutaneous coronary intervention (PCI) advancements enable revascularization for complex patients (CHIP).
• CHIP procedures require specialized interventional cardiologists.
• This review compares US and Japanese practice patterns for CHIP.

Observation:

• Presents two US-based CHIP cases: a male with myocardial infarction and cardiogenic shock, and a female with chronic total occlusion post-coronary artery bypass grafting complicated by perforation.
• Highlights key decision-making factors including patient selection, heart team approach, and hemodynamic support devices.

Findings:

• Identifies similarities and differences in CHIP practice patterns between Japan and the USA.
• Case examples illustrate the complexities and management strategies in CHIP interventions.

Implications:

• Comparing international practices can inform best practices for CHIP.
• Facilitates knowledge exchange to potentially enhance patient outcomes in complex PCI.
• Suggests areas for improvement in the global management of high-risk coronary interventions.
