Enhancing Risk Prediction After TAVI: The COPD-Augmented R₂CHA₂DS₂-VA Score and Its Prognostic Value

Highlight

– Development of the COPD-R9CHA2DS2-VA score integrating chronic obstructive pulmonary disease (COPD) and graded renal dysfunction for TAVI patients.
– Excellent discriminative accuracy for predicting one-year all-cause mortality with an internal bias-corrected AUC of 0.946.
– COPD’s addition significantly improved mortality prediction but not major adverse cardiovascular events (MACE).
– The tool requires external validation in diverse populations before routine clinical application.
