Figure 4. Which approach to use. This flow chart shows how to evaluate which approach would be best and how to choose between a surgical and percutaneous approaches. CABG: Coronary artery bypass grafting; TI: tricuspid insufficiency; RV: right ventricle; PAD: peripheral artery disease, PCI: percutaneous coronary intervention; TAVI: transcatheter aortic valve implantation; TMVR: transcatheter mitral valve replacement.
