Key Points

Retrograde stenting improved angina pectoris in a patient with complex cardiac history characterized by previous surgeries.
Patient experienced significant angina relief after retrograde stenting following transcatheter aortic valve replacement.
This observational case highlights the intricacies of managing patients with degenerative bioprosthetic aortic valves.
Findings support the potential for novel interventions, including retrograde techniques, to enhance patient outcomes in similar cases.

Implication

Case report reveals retrograde stenting improves angina pectoris in an 84-year-old after CABG, indicating potential for innovative approaches in coronary interventions.

Abstract

We report an interesting complex percutaneous coronary intervention (PCI) case in an 84‐year‐old male, with typical angina pectoris after previous coronary artery bypass graft (CABG) surgery and coronary double chimney stenting during a transcatheter aortic valve replacement (TAVR)‐in‐TAVR procedure with double self‐expanding transcatheter heart valve (THV) in his degenerated stentless aortic surgical valve bioprosthesis.
