Abstract

SARTOR, Lucio et al. Evaluation of the results of surgical reconstruction of the mitroaortic skeleton in active infective endocarditis. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.2, pp.140-145.  Epub Nov 23, 2016. ISSN 0120-5633.  http://dx.doi.org/10.1016/j.rccar.2016.07.007.

Introduction

: Surgical intervention of active infective endocarditis with multiple abscesses and destruction of the intervalvular fibrous body represents a technically demanding procedure with a difficult postoperative management. The experience is presented with an original technique for radical resection and subsequent reconstruction using bovine pericardium.

Material and methods:

During the last eight years in our centre 29 patients with active infective endocarditis and paravalvular abscesses that destroyed the microaortic union underwent surgery (20 over prosthesis and 9 over native valve): 13 of them reached the operating room with severe sepsis. Average EuroScore I of the series was 36 ± 22.7%. Treatment consisted of a broad resection of infected tissue and subsequent reconstruction of the fibrous body with glutaraldehyde fixed bovine pericardium, by means of an original technique.

Results:

Hospital mortality of the series was 20.7%. Average follow-up was 34.2 ± 28 months, with a maximum of 8 years. Two patients required a reoperation due to periprosthetic aortic valve leaks. Only one relapse of the infectious process was registered. Two patients passed away during follow-up after discharge, for non-cardiac reasons.

Conclusion:

Broad resection of the mitroaortic union and subsequent reconstruction with bovine pericardium can in some cases be the only surgical option to save a patient's life. The authors consider that the presented technique is a repeatable procedure, with acceptable morbidity and mortality, that would minimise the risk of future recurrence.
