A long-term follow-up study of valve replacements

Area of Science:

• Cardiovascular Surgery
• Clinical Outcomes Research

Background:

• Cardiac valve replacement is a critical intervention for severe valvular heart disease.
• Understanding long-term outcomes and social reintegration is essential for patient management.

Purpose of the Study:

• To evaluate the long-term results of valve replacement operations.
• To analyze the rates of social return following cardiac valve surgery.

Main Methods:

• Retrospective study of 591 patients undergoing valve replacement, with follow-up of one year or more.
• Social return assessment via questionnaire in 523 patients (86.1% response rate).

Main Results:

• Early mortality was 13.7% (81 patients), and late mortality was 6.9% (41 patients).
• Common causes of late death included left atrial thrombus, heart failure, and artificial valve failure.
• The 12-year survival rate was 68.7%.
• Overall social return rate was 64.8%, varying by valve type (mitral 74.8%, aortic 54.3%, multivalvular 51.5%).
• Social return rates improved to 76.4% in the most recent five-year period.

Conclusions:

• Valve replacement offers a significant survival benefit, with a 12-year survival rate of 68.7%.
• Social return is achievable, particularly after mitral valve replacement, and has shown recent improvement.
• Addressing complications like thrombus formation and valve failure is crucial for enhancing long-term patient outcomes.
