Résumé
The aim of the study was to assess some parameters of right ventricle (RV) function as predictors of short-term mortality in patients with severe secondary mitral regurgitation (SMR) after mitral valve surgery. We conducted a retrospective analysis of 112 consecutive patients with severe SMR who had undergone mitral valve repair or replacement with or without concomitant coronary artery bypass surgery. We assessed RV to pulmonary artery coupling by calculating the ratio of tricuspid annular plane systolic excursion (TAPSE) to non-invasively estimated RV systolic pressure (RVSP). The study endpoint was 30 days post-procedural mortality. Overall, the 30-day mortality was 6%. TAPSE/RVSP ratio < 0.42 mm/mmHg was a significant predictor of mortality and remained so after adjusting for age and sex. The Kaplan-Meier survival analysis showed that patients with RVSP > 55 mmHg and those with TAPSE/RVSP ratio < 0.42 mm/mmHg had a lower survival probability. TAPSE/RVSP < 0.42 mm/mmHg is a strong predictor of short-term mortality in patients with SMR when considered for valve surgery.

BACKGROUND
The aim of the study was to assess some parameters of right ventricle (RV) function as predictors of short-term mortality in patients with severe secondary mitral regurgitation (SMR) after mitral valve surgery.
METHODS
METHODS
We conducted a retrospective analysis of 112 consecutive patients with severe SMR who had undergone mitral valve repair or replacement with or without concomitant coronary artery bypass surgery. We assessed RV to pulmonary artery coupling by calculating the ratio of tricuspid annular plane systolic excursion (TAPSE) to non-invasively estimated RV systolic pressure (RVSP). The study endpoint was 30 days post-procedural mortality.
RESULTS
RESULTS
Overall, the 30-day mortality was 6%. TAPSE/RVSP ratio < 0.42 mm/mmHg was a significant predictor of mortality and remained so after adjusting for age and sex. The Kaplan-Meier survival analysis showed that patients with RVSP > 55 mmHg and those with TAPSE/RVSP ratio < 0.42 mm/mmHg had a lower survival probability.
CONCLUSIONS
CONCLUSIONS
TAPSE/RVSP < 0.42 mm/mmHg is a strong predictor of short-term mortality in patients with SMR when considered for valve surgery.
