Three cases of right-sided active endocarditis with multiple pulmonary infarction

Abstract

We have experienced three patients with right-sided active endocarditis combined with multiple pulmonary infarction. Ventricular septal defect (VSD), aortic regurgitation (AR), tricuspid regurgitation (TR) and congestive heart failure were present in case 1. TR was present in case 2. VSD, TR and patent ductus arteriosus were present in case 3. alpha-Streptococcus caused endocarditis in case 1 and 3; Candida albicans caused endocarditis in case 2. Antibotic therapy had no effect in case 2 and 3. Case 1 and 3 developed pulmonary hemorrhage, which resolved before the operation in case 1, but not in case 3. Our three patients underwent surgery and recovered successfully. They were discharged on the 43th, 58th and 32th postoperative day and are presently free of clinical symptoms. These experiences suggest surgery should be undertaken in the following situations: 1. antibiotic therapy has no effect on the infection, 2. hemodynamics are worsening, and 3, pulmonary infarction and pulmonary hemorrhage occur repeatedly.

Pulmonary Embolism Caused by Candida Albicans

“…The aim of surgical treatment is to remove vegetations while conserving the valve, and to extract pulmonary emboli. [4][5][6]…”
