About

Patients undergoing surgical aortic valve replacement (sAVR) with concomitant coronary artery disease (CAD) are known to have higher mortality rates compared to patients without CAD. This same phenomenom has not been clearly mapped in patients with CAD that goes through a transcatheter aortic valve implantation procedure.

Full description

A narrowing of the aortic valve, aortic stenosis, is a relatively common condition among the elderly. When the narrowing gets too severe, symptoms such as loss of breath, angina and fainting can occur, so called symptomatic aortic stenosis. Since the 60's, surgical aortic valve replacement (sAVR) has been the treatment of choice for severe aortic stenosis. A large setback of this method is that a third of these patients could not undergo the treatment due to too high surgical risk.

Transcatheter aortic valve implantation (TAVI) have steadily gained ground in the treatment of severe aortic valve stenosis during the last decade. The procedure, which is a minimal invasive type of surgery, introduces a new aortic valve through a catheter, usually transfemorally. Patients with an underlying coronary artery disease (CAD) undergoing sAVR is known to have higher mortality rates postoperatively. However, it is not clearly known how an underlying CAD affects the long term results after a TAVI-surgery. It is therefore our goal to contribute with the mapping of how a CAD affects the long term results for patients with a severe aortic valve stenosis that undergoes TAVI.
