Why the study?

Does the "bow-tie" mitral valve repair technique reduce mitral regurgitation and improve ejection fraction in patients with ischemic mitral regurgitation?

Key Points

To evaluate the effectiveness of the bow-tie mitral valve repair as an adjunct technique for ischemic mitral regurgitation.
Utilized bow-tie repair alongside posterior ring annuloplasty in 10 patients with mitral regurgitation.
Follow-up duration averaged 336 days, with a range of 82 to 551 days.
Clinical outcomes assessed included mitral regurgitation severity and ejection fraction before discharge.
Mitral regurgitation reduced significantly from 3.6 +/- 0.5 to 0.8 +/- 0.4 (p < 0.0001).
Ejection fraction increased from 33% +/- 13% to 45% +/- 11% (p = 0.0156).
Mitral valve area improved from 1.9 to 2.5 cm2 during exercise, indicating enhanced annular function.

Structured PICO

Does the "bow-tie" mitral valve repair technique reduce mitral regurgitation and improve ejection fraction in patients with ischemic mitral regurgitation?

Population

10 patients with ischemic mitral regurgitation undergoing mitral valve repair where MR was not adequately controlled by decreasing mitral valve area (n=6) or placement of an annuloplasty ring was impractical (n=4).

Intervention

"Bow-tie" mitral valve repair (apposing the anterior leaflet to a corresponding point on the posterior leaflet to create a double-orifice valve), used either as an adjunct to posterior ring annuloplasty or alone.

Outcome

Mitral regurgitation severity and ejection fraction before hospital dischargesurrogate

The "bow-tie" mitral valve repair technique significantly reduces mitral regurgitation and improves ejection fraction, serving as a useful adjunct in patients with ischemic MR and impaired left ventricular function.

Implication

Hypothesis-generating for bow-tie repair in ischemic MR; prospective trials needed before adoption.
