    Repeat closed mitral valvotomy is a viable option for restenosis, particularly with non-calcified valves. However, restenosis rates are higher with the finger fracture technique compared to the Tubbs dilator.

    Area of Science:

    • Cardiology
    • Cardiac Surgery

    Background:

    • Closed mitral valvotomy is a procedure to treat mitral stenosis.
    • Restenosis can occur after initial valvotomy, necessitating further intervention.

    Purpose of the Study:

    • To evaluate the outcomes of a second closed mitral valvotomy.
    • To compare the efficacy of different closed valvotomy techniques in preventing restenosis.

    Main Methods:

    • Retrospective review of 67 patients undergoing a second closed mitral valvotomy.
    • Comparison of restenosis rates between finger fracture and Tubbs dilator valvotomy.

    Main Results:

    • Restenosis requiring surgery occurred in 40% after finger fracture vs. 9.2% after Tubbs dilator valvotomy.
    • Operative and late mortality rates were 10.4% and 23.8%, respectively.

  • 70.5% of survivors had good or excellent results, with poor outcomes linked to calcified valves.

    • Conclusions:

    • A second closed mitral valvotomy can yield good results, especially for non-calcified valves.
    • The Tubbs dilator technique is associated with a lower restenosis rate than finger fracture.
    • Patient selection, particularly valve calcification, is crucial for successful outcomes.
