Prognostic value of psoas muscle area and pleural effusion in patients undergoing TAVI.

ABSTRACT:

Background

Radiographic markers such as psoas muscle area (PMA) and pleural effusion have been linked to mortality after transcatheter aortic valve implantation (TAVI). We examined their relationship with cause-specific mortality and their incremental prognostic value beyond EuroSCORE II.

Methods

This retrospective study included 1090 consecutive TAVI patients treated at Heart Hospital, Tampere University Hospital between 2008 and 2020. Preoperative CT scans were reviewed for L3-level PMA and pleural effusion (>10 mm thickness). Subdistribution hazard models adjusted for age, sex, BMI, and BSA were used to analyze cause-specific mortality. Incremental prognostic value beyond EuroSCORE II was assessed using time-dependent discrimination indexes (AUC and IDI) and net-reclassif
