Clinical Follow-up of Patients Undergoing Percutaneous Mitral Balloon Valvotomy
Why the study?
Does a baseline echocardiographic score <= 8 predict better intermediate long-term survival and freedom from combined events compared to a score > 8 in patients undergoing percutaneous mitral balloon valvotomy?

Implication
May aid echo-based risk stratification for PMBV; leaves open prospective validation before guiding selection.
Structured PICO
Does a baseline echocardiographic score <= 8 predict better intermediate long-term survival and freedom from combined events compared to a score > 8 in patients undergoing percutaneous mitral balloon valvotomy?
P
Population
327 patients undergoing percutaneous mitral balloon valvotomy (PMV) at a single center (Massachusetts General Hospital), divided into two groups based on echocardiographic score (n=211 with score <= 8; n=116 with score > 8).
I
Intervention
Percutaneous mitral balloon valvotomy (PMV) in patients with an echocardiographic score <= 8
C
Comparator
Percutaneous mitral balloon valvotomy (PMV) in patients with an echocardiographic score > 8
O
Outcome
Rates of survival, survival with freedom from mitral valve replacement, and survival with freedom from combined events at intermediate long-term follow-uphard clinical
An echocardiographic score <= 8 is a strong predictor of excellent intermediate long-term survival and freedom from mitral valve replacement following percutaneous mitral balloon valvotomy.
