Management of left main coronary artery obstruction after transcatheter aortic valve replacement utilizing a...

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Coronary obstruction is a rare but life-threatening complication following transcatheter aortic valve replacement (TAVR).
• Obstruction can occur due to native valve leaflets or the TAVR stent frame impeding coronary ostia access.
• Percutaneous coronary intervention (PCI) after TAVR presents unique challenges.

Observation:

• Standard PCI techniques may be hindered by the braided nitinol frame of TAVR devices.
• Limited case reports exist on managing coronary access post-TAVR, with no description of a periscope approach.
• This case highlights the difficulty in accessing coronary arteries when TAVR stent struts obstruct the ostia.

Findings:

• A novel periscope approach was successfully employed to access the left main ostia.
• This technique facilitated equipment delivery despite the presence of a braided nitinol TAVR frame.
• The described method provides an alternative strategy for coronary artery access in challenging post-TAVR anatomies.

Implications:

• This periscope technique offers a potential solution for managing coronary obstruction post-TAVR.
• It expands the interventional cardiologist's toolkit for complex PCI cases.
• Further investigation and adoption of such alternative approaches may improve outcomes for patients experiencing TAVR-related coronary complications.
