Medical treatment or surgical intervention? A cooperative retrospective study on infective endocarditis--timing of operation.
Two hundred and five patients treated for infective endocarditis over the last 10 years were reviewed. There were 185 cases of native valve endocarditis (NVE) and 20 of prosthetic valve endocarditis (PVE). In the NVE group there were 175 clinically active patients and 10 non-active patients. The mortalities among 108 non-surgical and 57 surgical patients were 15.7% and 14.0%, respectively. Leading causes of deaths in the former were cardiac failure, embolism and cerebral hemorrhage. Patients with embolism showed significantly higher mortality. Culture negative endocarditis resulted in almost the same incidence of hospital death and urgent operation as staphylococcal endocarditis, and a higher incidence than streptococcal endocarditis. In 9 of 33 patients operated at our hospital, surgery was performed on an urgent basis and one NYHA class IV patient died. Indications for operation were intractable cardiac failure, uncontrollable infection and angina. In the PVE group, 3 of 4 patients operated in the active stage died of severe cardiac failure generated preoperatively. The only survivor was a patient operated early under stable hemodynamics. These results suggest that culture negative endocarditis should be observed as closely as staphylococcal endocarditis and early operation should be considered for patients with progressive cardiac failure, embolism and uncontrollable infection.
