Does percutaneous balloon mitral valvuloplasty improve left atrial reservoir function and volume in patients with severe mitral stenosis?
Does percutaneous balloon mitral valvuloplasty improve left atrial reservoir function and volume in patients with severe mitral stenosis?
Percutaneous balloon mitral valvuloplasty significantly improves left atrial reservoir function and reduces LA volume in patients with severe mitral stenosis, though the benefit is attenuated in those with atrial fibrillation or prior stroke.
Post-BMV LA reservoir gains may be attenuated by AF or prior stroke; hypothesis-generating and should not yet change practice.
; p=0.002). Those with AF had lesser improvement in PALS in comparison to those with NSR (60% vs. 84%; p=0.044) at three months of follow-up. At three months, the increase in PALS was also lower in patients with a history of stroke as compared to those without it (55% vs 80%; p=0.039). Both LA volume and indexed LA volume reduced significantly immediately at 24 hours and during follow-up. Conclusion LA reservoir function, as assessed by PALS, is reduced in patients with severe MS. It improved significantly within 24 hours following BMV and continued to improve at three months of follow-up. It is an underutilized modality among patients of MS for decision-making prior to intervention and to assess the effect of the intervention.
