[Current results of the aortic valve changes].
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.
