Neo Left Main Creation and Percutaneous Closure of Left Coronary Button Pseudoaneurysm After Bentall Procedure.

ABSTRACT:

Background

Pseudoaneurysms are a rare but serious complication after aortic valve replacement and Bentall procedures, posing management challenges in high-risk patients.

Case summary

A 78-year-old woman with prior aortic valve replacement and Bentall surgery developed a pseudoaneurysm at the left coronary artery anastomosis, detected 4 years later during routine echocardiography. Computed tomography revealed a 35 × 29-mm saccular pseudoaneurysm at the left coronary artery button. A percutaneous approach was chosen, deploying a drug-eluting stent from the left main coronary artery ostium to the aortic graft, creating a supportive tunnel. A coronary stent graft was placed within this tunnel, forming a neo left main coronary artery. Endovascular coils successfully occluded the
