Atrial septal occlusion improves the accuracy of mitral valve area determination following percutaneous mitral balloon valvotomy
Why the study?
Does balloon occlusion of the atrial septal puncture site improve the accuracy of mitral valve area calculation in patients following percutaneous mitral balloon valvotomy?
Population
17 patients (15 women, 2 men; mean age 56 +/- 4 years) following percutaneous mitral balloon valvotomy
Comparison
Hemodynamic measurements and mitral valve area… vs Hemodynamic measurements and mitral valve area…

Implication
Balloon occlusion may improve post-PMBV mitral valve area accuracy; hypothesis-generating pending prospective validation.
Structured PICO

P
Population
17 patients (15 women, 2 men; mean age 56 +/- 4 years) following percutaneous mitral balloon valvotomy
I
Intervention
Hemodynamic measurements and mitral valve area calculations with balloon occlusion of the atrial septal puncture site
C
Comparator
Hemodynamic measurements and mitral valve area calculations without balloon occlusion of the atrial septal puncture site
O
Outcome
Mitral valve area calculationsurrogate
Balloon occlusion of the atrial septal puncture site during hemodynamic measurement provides a more accurate calculation of mitral valve area after percutaneous mitral balloon valvotomy by preventing the confounding effect of atrial communication.
