    This study details the first percutaneous mitral valvotomy in Portugal, successfully treating calcific mitral stenosis. The minimally invasive procedure significantly improved the patient

    Area of Science:

    • Cardiology
    • Interventional Cardiology
    • Cardiac Surgery

    Background:

    • Calcific mitral stenosis is a severe valvular heart disease.
    • Percutaneous mitral valvotomy offers a less invasive treatment option.
    • The transseptal technique is a key approach for mitral valve interventions.

    Observation:

    • The first percutaneous mitral valvotomy in Portugal was performed on October 19, 1987.
    • A 34-year-old male patient with severe calcific mitral stenosis (NYHA class III, MVA < 1 cm2) was treated.
    • The procedure utilized a transseptal technique with two balloons (20 and 18 mm).

    Findings:

    • Successful valvotomy achieved a significant reduction in transmitral gradient.
    • Mitral valve area increased by over 100%, indicating procedural success.

  • No immediate or late complications such as mitral regurgitation or shunt were observed.

    • Implications:

    • Percutaneous mitral valvotomy is a safe and effective treatment for severe mitral stenosis.
    • This landmark procedure established a new treatment modality in Portugal.
    • Long-term follow-up showed sustained clinical improvement (NYHA class I, MVA 1.7 cm2).
