Aim
In patients with pulmonary dysfunction, it is unclear wheather transcatheter aortic valve implantation (TAVI) is well tolerated or even beneficial. We investigated wheather transfemoral access valve implantation leads to more favorable outcomes than transaortic valve implantation in patients with chronic lung disease by using forced expiratory volume in 1 second as a surrogate.
Methods
From June 2013 to November 2014, 96 patients undervent transcatheter aortic valve replacement, 46 had forced expiratory volume in 1 second measured and expressed as percent of predicted (FEV1%, 36 via femoral access, 10 via transaortic access). Pre and postoperative outcomes were compared among to groups of TAVI. All patients had significant aortic stenosis and high risk patients regarding to logistic euroscore(>20). Spirometry was available in 46 of the 96 patients with a preoperative diagnosis of chronic obstructive pulmonary disease (COPD). However, the FEV1 / FVC ratio was < 70 % of these patients met the GOLD criteria for the diagnosis of COPD.
