Role of Real-Time 3D-Echocardiography in Predicting Success of Redo-Percutaneous Balloon Mitral Valvuloplasty

Abstract

Background

Echocardiographic predictors of procedural success of redo-percutaneous balloon mitral valvuloplasty (redo-pBMV) have not been extensively studied, and current indications are primarily based on the Wilkins score (WS).

Aim

This study aims to evaluate the role of real-time 3D echocardiography in predicting the success rates of redo-pBMV.

Methodology

We analyzed 42 patients who underwent pBMV at our center from January 2022 to November 2022. These patients were divided into two groups: Group I (patients undergoing redo-pBMV) and Group II (patients undergoing pBMV for the first time). Immediate procedural outcomes were assessed, and the 3D echocardiographic score was compared with the traditional WS.

Results

The mean WS was 9.69 ± 1.08 in Group I, compared to 9.5 ± 1.33 in Group II (p = 0.575). The 3D echocardiographic analysis revealed a numerically higher 3D score in Group I (11.2 ± 1.83 vs. 10.9 ± 1.52, p = 0.631). ROC curve analysis showed an area under the curve (AUC) of 0.9785 for the 3D score, indicating that it was a better predictor of success compared to the WS (ROC AUC = 0.8289).

Conclusion

The real-time 3D echocardiographic score provides a detailed morphological assessment of the mitral valve and was found to be a better predictor of procedural success than the traditional WS in patients undergoing redo mitral stenosis intervention.
