An increase >3 B-lines after exercise predicted PMBV need in mitral stenosis with 85.7% sensitivity and 66.2% specificity (AUC 0.69, p=0.006).
Does lung ultrasonography assessment of B-lines correlate with mitral stenosis severity and predict the need for percutaneous mitral balloon valvuloplasty?
Exercise-induced changes in B-lines on lung ultrasonography can help predict the need for percutaneous mitral balloon valvuloplasty in patients with mitral stenosis.

ABSTRACT Background This study investigated the relationship between mitral stenosis (MS) severity and B‐line counts on lung ultrasonography (US) and their predictive value for PMBV requirement. Methods A total of 105 patients (70 MS, 35 controls) underwent transthoracic echocardiography (ECHO) and lung US using a 28‐point protocol. Patients performed an exercise test to 85% of their predicted heart rate, followed by repeat imaging. B‐line changes were analyzed by MS severity and symptoms. Results MS patients had significantly more B‐lines than controls ( p 3 B‐lines in the left hemithorax after exercise predicted percutaneous mitral balloon valvuloplasty (PMBV) with 85.7% sensitivity and 66.2% specificity (AUC 0.69, p = 0.006). Conclusions Lung US assessment of B‐lines may assist in determining the optimal timing for intervention in MS, particularly in asymptomatic severe and symptomatic mild‐to‐moderate cases, where conventional ECHO findings may be inconclusive.
