Summary
OBJECTIVES: With the popularization of catheter-based mitral valve procedures, evaluating risk-specific differentiated clinical outcomes after contemporary mitral valve surgery is crucial. In this study, we assessed the operative results of minimally invasive mitral valve operations across different patient risk profiles and evaluated the value of EuroSCORE (ES) II predicted risk of mortality model for risk prediction, in the large cohort of Mini-Mitral International Registry (MMIR). METHODS: The MMIR database was used to analyse mini-mitral operations between 2015 and 2021. Patients were categorized as low (<4%), intermediate (4% to <8%), high (8% to <12%) and extreme risk (≥12%) according to ES II. The observed-to-expected mortality ratio was calculated for each risk group. RESULTS: A to
