Comprehensive management of severe intestinal bleeding in a patient supported for 94 days by the biventricular Levitronix CentriMag system.

The use of short-term mechanical circulatory support during postcardiotomy acute heart failure provides an opportunity to stabilize the patient's hemodynamic state while determining the best long-term strategy. Because all of these devices require anticoagulation treatment of various intensities, management of major bleeding can be critical for the overall outcome of the therapy. In this regard, the newest generation of magnetically levitated centrifugal-flow pumps affords several potential advantages in terms of thrombogenicity and eventual discontinuation of anticoagulation treatment. We report the use of a short-term biventricular assist device (Levitronix CentriMag) for 94 days in a 55-year-old man with refractory ventricular arrhythmias after combined heart surgery. Despite serious complications while the patient was on the assist device, including severe intestinal bleeding with the necessity of discontinuing anticoagulation for 10 days and, ultimately, hemicolectomy, the circulatory support was completed with successful heart transplantation.

Two sporadic infected cardiac myxomas in 1 patient.

Infected cardiac myxoma is a rare cause of endocarditis. The finding of coexisting infected cardiac myxomas is highly unusual. Herein, we present the case of a 58-year-old woman with a low-grade fever. Laboratory findings strongly indicated inflammation, and blood cultures detected Staphylococcus species. Echocardiograms revealed mobile masses in the area of the mitral valve. Transesophageal echocardiograms showed 2 formations that arose from opposite sides of the mitral annulus and protruded into the left ventricle during systole. During emergency surgery, 2 abnormal growths with numerous vegetations were completely excised. The diagnosis of myxoma was confirmed upon histologic evaluation. Microbiological and polymerase chain reaction analysis of the myxomas detected the bacterial strain Enterococcus faecalis. Five months postoperatively, the patient showed no signs of recurrent infection and had a normal echocardiographic appearance.This report is the first of an infected cardiac myxoma in the Czech population and one of approximately 60 reports in the medical literature from 1956 to the present. In addition to the case of our patient, we discuss the discrepancy between the bacteriologic findings.
