[Multivalvular replacement: short and long term results in 367 cases (author's transl)]

Area of Science:

• Cardiovascular Surgery
• Valvular Heart Disease
• Surgical Outcomes

Context:

• Between 1964 and 1973, a significant number of patients underwent complex valvular replacement surgeries.
• The study evaluated early and late results for three types of procedures: mitro-aortic, mitro-tricuspid, and combined mitro-aortic-tricuspid replacements.

Purpose:

• To assess and compare the outcomes of different types of mitral valve replacement surgeries.
• To analyze hospital mortality rates and long-term survival probabilities following these procedures.

Summary:

• A total of 367 valvular replacements were analyzed: 273 mitro-aortic, 66 mitro-tricuspid, and 28 combined. Hospital mortality rates were 17.5% (mitro-aortic), 30.5% (mitro-tricuspid), and 10.7% (combined).
• Mitro-aortic replacement demonstrated superior results compared to mitro-tricuspid replacement, which was associated with poorer functional rehabilitation.
• Actuarial analysis indicated a 9-year survival probability of 67% for mitro-aortic and 47% for mitro-tricuspid replacements.

Impact:

• Highlights the critical differences in outcomes between various mitral valve replacement strategies.
• Provides valuable long-term data for surgical decision-making in valvular heart disease.
• Suggests that mitro-aortic valve replacement offers a more favorable prognosis than mitro-tricuspid replacement.
