Valvular & structural heart disease
Trends and Late Outcomes in Elderly Patients Undergoing Mitral Valve Interventions in the United States
Authors' conclusion
Mitral valve interventions in elderly patients are increasing over time, driven by transcatheter therapies. Five-year mortality varied by type of intervention and was significantly influenced by frailty and social vulnerability.
