Severe Aortic Valve Stenosis and Concomitant Coronary Artery Disease in Patients Undergoing TAVI
Severe Aortic Valve Stenosis and Concomitant Coronary Artery Disease in Patients Undergoing TAVI
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.
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.
Inclusion Criteria:

 -  All patients that underwent a TAVI procedure at Örebro University Hospital between
 2009 till 1st december 2019.

 Exclusion Criteria:

 -  Patients with procedural-related coronary artery injury and patients with solitary
 stenosis in a diagonal branch were excluded from the study.
