View Full PaperImpact of cardiac resynchronization therapy on the severity of mitral regurgitation
Key Result
Improvement in mitral regurgitation at 3 months predicts cardiac resynchronization therapy response and further MR improvement at 12 months.
Structured PICO
Does mitral regurgitation improvement at 3 months predict CRT response and MR improvement at 12-month follow-up?
P
Population
Patients undergoing cardiac resynchronization therapy (CRT)
I
Intervention
Cardiac resynchronization therapy (CRT)
O
Outcome
CRT response and mitral regurgitation (MR) improvement at 12-month follow-upsurrogate
Early improvement in mitral regurgitation at 3 months post-CRT predicts long-term CRT response and sustained MR improvement at 12 months, which may guide subsequent surgical decisions.
Main Result
Absolute Event Rate: 0% vs 0%
Abstract
Mitral regurgitation improvement at 3 months predicts CRT response and MR improvement at 12-month follow-up. This finding could have implications for subsequent MR surgical therapies.
