Predictive factors of early mortality after transcatheter aortic valve implantation: individual risk assessment using a simple score

The FRANCE  2 investigators have developed a scoring system to predict the risk of in-hospital or 30-day mortality for patients undergoing TAVI. There were 3833 TAVIs used for  development and validation of the scoring system with the majority of patients receiving an Edwards Sapien prosthesis. Risk factors for early mortality included age greater than or equal to 90, BMI greater than 30, NYHA class IV, pulmonary hypertension, critical haemodynamic state, more than 2 episodes of pulmonary oedema in the first year, respiratory insufficiency, dialysis and implantation route other than subclavian. The developed 21-point scoring system only demonstrated average discriminatory ability.
