[Transcutaneous coronary intervention accompanied by biventricular circulatory support and combined with...

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Medical Technology

Background:

• Coronary artery bypass grafting (CABG) is often contraindicated in patients with multiple-vessel disease, comorbidities like obesity, low ejection fraction, and prior CABG.
• Percutaneous coronary intervention (PCI) in these high-risk patients carries significant risks, especially with complex lesions and large myocardial territories.
• Existing hemodynamic support methods like intra-aortic balloon pumps and left ventricular assist devices have limitations for high-risk PCI.

Observation:

• This case report details a patient with complex coronary artery disease who was not a candidate for conventional revascularization.
• The patient underwent technically challenging stenting of the unprotected left main coronary artery and the right coronary artery.
• Mechanical circulatory support was achieved using a biventricular bypass in conjunction with extracorporeal membrane oxygenation.

Findings:

• Successful stenting of the unprotected left main and right coronary arteries was performed.
• The use of a mechanical biventricular bypass provided effective hemodynamic support throughout the high-risk intervention.
• This approach mitigated the shortcomings associated with other hemodynamic support modalities.

Implications:

• Biventricular bypass combined with extracorporeal membrane oxygenation offers a viable and effective hemodynamic support strategy for high-risk percutaneous coronary intervention.
• This technique may expand treatment options for complex coronary artery disease patients previously deemed unsuitable for revascularization.
• Further research into this combined support system for complex PCI is warranted.
