Contemporary surgical or percutaneous management of severe aortic stenosis in the elderly

Abstract

Aims: To assess patient characteristics, therapeutic options, and their results in patients referred to a tertiary centre with on-site capabilities for surgical and percutaneous valvular interventions for the management of severe symptomatic aortic stenosis (AS).

Methods and results: Sixty-six consecutive patients >70 years (83 +/- 6 years) were referred for severe AS. Their mortality risk predicted by the logistic European System for Cardiac Operative Risk Evaluation and the Society of Thoracic Surgeons-Predicted Risk of Mortality scores were on average 20 +/- 14% and 17 +/- 7%, respectively. Thirty-nine patients (59%) were considered at high-risk for surgery or inoperable after multidisciplinary evaluation: 12 (31%) underwent a transfemoral aortic valve implantation and 27 were considered unsuitable and treated medically (n = 16) or with valvuloplasty (n = 7), or were re-directed towards surgery (n = 4). The 27 other patients underwent valve replacement. In-hospital mortality was 9% (6 of 66). There were three hospital deaths in patients treated percutaneously, two in those treated medically, and one after surgery. At 6 months, 10% (6 of 60) of the survivors died: two after valvuloplasty and four after medical treatment.

Conclusion: A large proportion of elderly patients referred for management of severe AS have a high-risk profile. The availability of percutaneous valvular interventions increases the number of those who are offered interventions.
