Key result
Left-to-right atrial shunting was detected in 62% of patients immediately after percutaneous mitral valvuloplasty, though its severity almost always decreased by 6 months.

Atrial shunting may occur after PMV; leaves open its long-term clinical impact and need for prospective study.
Observational (n=68)
What is the incidence and long-term evolution of left-to-right atrial shunting after percutaneous mitral valvuloplasty?
Absolute Event Rate: 62% vs 0%
Left-to-right atrial shunting is common immediately after percutaneous mitral valvuloplasty but its severity almost always decreases or resolves by 6 months.
Cequier et al. (1990) conducted an observational in Patients undergoing percutaneous mitral valvuloplasty (n=68). Percutaneous mitral valvuloplasty vs. Pre-procedure (baseline) was evaluated on Incidence of left-to-right atrial shunting. Left-to-right atrial shunting was detected in 62% of patients immediately after percutaneous mitral valvuloplasty, though its severity almost always decreased by 6 months.
