[Current results of the aortic valve changes].

F López Soriano, J C Barnet, F Quijano Pitman

    Archivos Del Instituto De Cardiologia De Mexico
    |November 1, 1979
    PubMed
    Summary

    Aortic valve replacement surgery has improved, with one surgeon reporting 0% mortality. Early surgery for aortic valve disease is recommended due to better outcomes compared to natural disease progression.

    Area of Science:

    • Cardiovascular Surgery
    • Prosthetic Valve Technology

    Context:

    • Aortic valve replacement (AVR) has seen significant advancements, reducing surgical and hospital mortality.
    • Historical data from 1973-1978 at the "Instituto Nacional de Cardiología" showed an 11.3% early mortality rate for 167 AVR patients.

    Purpose:

    • To evaluate the outcomes and mortality rates of aortic valve replacement surgery.
    • To compare surgical results with the natural history of aortic valve disease.

    Summary:

    • One surgeon achieved 0% mortality in 40 isolated or associated AVR cases.
    • Post-operative myocardial infarction rates were 8% (lower than the reported 15%).
    • Thromboembolic events occurred in 5.3% of patients, with no fatalities.

    Impact:

    • Results support early surgical intervention for moderately symptomatic aortic valve disease.
    • Advancements in AVR techniques and prosthetic valve selection are crucial for improving patient outcomes.
    • The study highlights the need to discard prosthetic models with high malfunction rates, like the Starr Edward Model 2320.
