Overall objective: To describe the demographic, morbidity and indications for valvular heart valve surgery, operated with ON-X mechanical valves at the San Ignacio Hospital between 2006-2015. Describe the experience of the Hospital, the reasons for the surgeries and the evolution of these, with special emphasis on type and level of anticoagulation and complications.
Methods: Descriptive observational study based on the surgical registry of the Cardiovascular Surgery service of San Ignacio Hospital during the years described. From this registry, the information was searched in the medical records of all patients treated at the Hospital during the period between 2006 and 2015, an update to 2019 who received one or two ON-X mechanical valves, either due to an isolated valvular heart disease or for valvulopathy associated with another heart disease, such as ischemic heart disease.
We excluded only incomplete medical records or those in which postoperative follow-up data could not be obtained.
The data are useful to know the HUSI experience with ON-X mechanical valves and to compare, with the necessary precautions for population differences, with other similar institutions in Colombia and in world literature.
Results: A total of 305 patients were taken at aortic or mitral valve exchange and received mechanical On-X prostheses.
There was 30-day mortality in 30 patients given the high morbidity and complexity of procedures. At one year, 6 patients were added to mortality.
Conclusions: The ON-X valves have shown advantages over other valves on the market, related to their structure, which decreases the pannus formation, and the results in relation to the PROACT study increase the interest for this type of valve.
