|January 5, 2002
Summary
The modified Ross operation for aortic valve disease shows excellent mid-term results with low complications. This root replacement technique, utilizing autografts, demonstrates favorable hemodynamics and justifies continued use in suitable patients.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Cardiac Transplantation
Background:
- The Ross operation, a complex aortic valve replacement procedure, has evolved over three decades.
- Modifications aim to enhance technical feasibility and clinical outcomes.
- This study evaluates the Ross operation performed as root replacement since 1995.
Purpose of the Study:
- To assess the mid-term outcomes of the modified Ross operation.
- To evaluate the safety and efficacy of aortic root replacement using autografts.
- To analyze complications and reoperation rates associated with this technique.
Main Methods:
- A cohort of 225 patients underwent the Ross operation between 1995 and 2000.
- Patients presented with aortic regurgitation, stenosis, or combined disease.
- Follow-up was 98% complete, totaling 471 patient-years.
Main Results:
- No early mortality was observed; low rates of perioperative complications including myocardial infarction and bleeding.
- Long-term reoperations were required in 4 patients due to autograft regurgitation.
- Echocardiography showed favorable autograft hemodynamics with minimal regurgitation.
Conclusions:
- The evolved Ross operation as root replacement yields excellent mid-term hemodynamic results.
- Low morbidity and reoperation rates support the continued utilization of this technique.
- Specific surgical modifications appear to prevent autograft failure.
