[Surgery for infectious endocarditis].

OBJECTIVE
to assess the experience of both departments in the surgical therapy of infective endocarditis--indications and results.


DESIGN
retrospective analysis on clinical data, surgery and follow up.


SETTING
patients (pts) studied in the Cardiology Department and Cardiothoracic Surgery Department of the Santa Marta Hospital in Lisbon.


PATIENTS AND INTERVENTIONS
sequential sample of 28 patients (11 females, 17 males, mean age 39 years) submitted to surgery between 1978 and 1987 for infective endocarditis.


MEASUREMENTS AND RESULTS
the indications for surgery were: heart failure (15 pts), "resistant" infection (8 pts), emboli (4 pts) and "large" vegetations shown by echocardiography (2 pts). Surgical mortality -27.5%. Four patients developed periprosthetic leaks. There was an improvement in functional class of the survivals.


CONCLUSION
the indications for surgery were heart failure, "resistant" infection, emboli and "large" vegetations. There was a high surgical mortality, namely in the patients with resistant infection, severe heart failure and periprosthetic leaks. In the follow up there was a net improvement of functional class. The morbidity is due to the periprosthetic leaks, which induced most of the reoperations.
