Key result
A pre-procedural mitral valve commissural score of ≥2 strongly predicted a good outcome after balloon mitral valvotomy, demonstrating a positive predictive value of 96.7% and a negative predictive value of 80.0%.
Why the study?
The study was conducted to evaluate the accuracy of the mitral valve commissural score via transesophageal echocardiography and correlate it with balloon mitral valvotomy outcomes.

Shahid et al. (2023) conducted an observational in Mitral valve stenosis (n=171). Pre-procedural mitral valve commissural score ≥ 2 vs. Mitral valve commissural score < 2 was evaluated on Good procedural outcome (satisfactory hemodynamic result) (PPV 96.7%, NPV 80.0%). A pre-procedural mitral valve commissural score of ≥2 strongly predicted a good outcome after balloon mitral valvotomy, demonstrating a positive predictive value of 96.7% and a negative predictive value of 80.0%.
