Aortic Disease and Treatment Approaches

Although the first pulmonary autograft operations were performed in Spain in 1991, this procedure has gained substantial interest and has been consolidated since 1997. The establishment of the Spanish Registry of the Ross Operation pretends to evaluate the results of this option in aortic valve disease patients in our setting.In a yearly fashion, the cardiac surgery departments in Spain currently performing this intervention send data from new patients or follow-ups to the reference center. Preoperative, intraoperative and postoperative data are included in the registry, with special attention to morbidity, mortality, autograft and homograft dysfunction and need for reintervention.Since February 1991 to May 2002, 169 patients have been treated with this technique. The most prevalent aortic disease was regurgitation (72; 42.59%), congenital being the most frequent etiology (108; 63.9%). Four (2.36%) patients required intraoperative aortic counterpulsation. Operative mortality was 2.36% (n=4). Follow-up is 98.7% complete, with an average of 36.08+/-31.09 months (range 1-135), 84 patients (49.7%) were followed for more than 2 years. The autograft remains competent or with trivial to mild regurgitation in 161 patients (95.6%), presenting two (1.18%) with severe regurgitation. The homograft was normal or with mild stenosis in 159 patients (94.07%), presenting five (2.95%) with severe stenosis. Three (1.77%) required reintervention (surgical or interventional) on the right ventricular outflow tract and four (2.36%) required autograft replacement for a mechanical prosthesis. Actuarial survival is 95.99+/-1.65% at 36 months, remaining 92.44+/-2.55% free from reintervention in the same period.The Ross operation is an increasingly popular surgical option in Spain, and although the number of patients and length of follow-up are still limited, initial results are at least as good as those reported internationally. It is important to continue a close follow-up of these patients to assess the long-term function of auto and homograft. With the available data, we believe that this therapeutic approach is a valid option for selected groups of patients with surgical aortic valve disease in Spain.
