Insights
Cardiovascular surgery is increasing, with coronary artery bypass graft remaining common. However, procedures for heart valves and congenital heart disease are rising, with mortality rates higher than international benchmarks.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Public Health
Background:
- Advancements in percutaneous techniques, clinical treatment, and primary prevention are transforming cardiovascular surgery.
- The Instituto do Coração (InCor-HCFMUSP) is a key tertiary reference center for cardiovascular procedures in Brazil.
Purpose of the Study:
- To evaluate the incidence and mortality trends of heart surgeries performed at the Instituto do Coração (InCor-HCFMUSP) between 1984 and 2007.
Main Methods:
- A retrospective analysis of cardiovascular surgery data from the Instituto do Coração database.
- Examination of trends in main surgical procedures and associated mortality rates over a 24-year period.
Main Results:
- A total of 71,305 heart surgeries were performed, averaging 2,971 annually.
- Significant increases observed in heart valve procedures (36.7%) and congenital heart disease repair (50.8%) compared to the 1990s.
- While overall mortality decreased slightly from 7.5% to 7.0%, elective procedure mortality is 4.9%, with specific rates for coronary artery bypass graft (4.8%), valve surgery (8.5%), and congenital heart disease repair (5.3%).
Conclusions:
- Cardiovascular surgery volume continues to grow, with coronary artery bypass graft still the most frequent procedure.
- There is a notable shift towards increased complexity in procedures, particularly for cardiac valves and congenital heart disease.
- Mortality rates at this national reference center remain higher than international standards, indicating the high complexity of cases managed.
Background:
Cardiovascular surgery has been undergoing transformations due to the advancement of percutaneous techniques, clinical treatment and primary prevention.
Objective:
Evaluation of incidence and mortality of heart surgeries performed at the Instituto do Coração (InCor-HCFMUSP).
Methods:
Using database from the Instituto do Coração, analysis was carried out on cardiovascular surgeries performed between 1984 and 2007, taking into consideration trends of main procedures and of mortality rates.
Results:
In 24 years, 71,305 heart surgeries were performed, with an annual average of 2971 procedures. The number of coronary artery bypass graft surgeries, which in the 1980s had an average of 856/year, is currently around 1.106/year. Heart valve procedures increased from 400 to 597 surgeries per year, growing 36.7%, when compared to the 1990s. Repair of congenital heart disease also had a significant increase of 50.8% in relation to the last decade. Global mortality average rate, which at baseline was 7.5%, is currently at 7.0% and 4.9% among elective procedures. In coronary artery bypass graft surgery, current average mortality rate is 4.8% and 8.5% in valve surgery. Repair of congenital heart disease accounts for 5.3%.
Conclusion:
Cardiovascular surgery continues increasing. The coronary artery bypass graft is still the most commonly performed surgery. However, profile of procedures has been undergoing changes with the largest increase of approach to cardiac valves and congenital heart disease. Mortality rates are higher when compared to international rates, reflecting the high complexity presented in tertiary service of national reference.
