European Journal of Cardio-Thoracic Surgery, 06/01/2012
D'Onofrio A et al. – Patients undergoing TAVI with preoperative MR ≥ 2+ have a higher surgical risk profile and a trend towards higher hospital mortality. MR was not identified as a risk factor for mortality. At follow–up, a reduction in MR and an improvement of echocardiographic parameters were observed in the MR group.
