Coronary atherosclerosis is a common finding in patients with severe aortic stenosis. Indeed, aortic stenosis is associated with risk factors similar those of coronary atherosclerosis such as older age, hypertension, diabetes, hypercholesterolemia and smoking. In light of the evolution of percutaneous aortic valve implantation (PAVI) and ongoing improvements in techniques of PCI, a combined approach using PCI and PAVI can be proposed for patients with complex coronary artery and aortic valve disease. This report describes the feasibility of the combination of percutaneous coronary intervention and percutaneous aortic valve implantation with peripheral left ventricular assist device (TandemHeart) support in 3 elderly patients with complex coronary altery disease and aortic stenosis considered too high risk for conventional surgical therapy.
