A case of Cardiobacterium valvarum endocarditis with cerebral hemorrhage after MVR, TVP and vegetation removal operation.
Annals of clinical microbiology and antimicrobials, 2018Co-Authors: Xiaoying Xie, Nengyong Ouyang, Baiji Chen, Dongye Wang, Xiaoqiang Liu, Jiajian Guo, Yandan YaoAbstract:Cardiobacterium is a fastidious Gram-negative bacillus, and is a rare human pathogen in clinical settings. Herein, we describe a case of Cardiobacterium valvarum (C. valvarum) endocarditis with a rare complication of cerebral hemorrhage after mitral Valve replacement (MVR), Tricuspid Valve Prosthesis (TVP) and vegetation removal operation. A 41-year-old woman who had a history of gingivitis developed into infective endocarditis due to the infection of C. valvarum. Then, she was hospitalized to receive MVR, TVP and vegetation removal operation. The indicators of patient tended to be normal until the abrupt cerebral hemorrhage occurred on day 15 after operation. This is the first well-described case of C. valvarum infection in China, and the first report of C. valvarum endocarditis with cerebral hemorrhage after MVR, TVP and vegetation removal operation worldwide. We reported the first case of C. valvarum infection in China clinically, with a rare complication of cerebral hemorrhage after MVR, TVP and vegetation removal operation.

Thrombosis of bileaflet Tricuspid Valve Prosthesis: clinical spectrum and the role of nonsurgical treatment.
American heart journal, 1999Co-Authors: Y Shapira, A Sagie, R Jortner, Y Adler, R HirschAbstract:Thrombosis of a mechanical Tricuspid Valve Prosthesis is a potentially hazardous event. This study aimed to explore the incidence and the clinical presentation of Tricuspid Valve thrombosis occurring in bileaflet Valves and to evaluate the diagnostic and the therapeutic approach. Tricuspid Valve thrombosis was sought in 22 late survivors with the CarboMedics Valve in a follow-up period of 36.0 +/- 20.8 months. Limited leaflet motion and/or a visible thrombus were considered diagnostic of Valve thrombosis. Eight episodes of Tricuspid Valve thrombosis were diagnosed among 5 patients (12.1 episodes per 100 patient-years). Anticoagulation was inadequate in 3 patients and fair in 2. Florid right heart failure occurred in 3 episodes. Common physical findings included increased jugular venous pulse (5 patients), diastolic Tricuspid murmur (4 patients), and peripheral edema (4 patients). The diagnosis was suspected in all clinically and by transthoracic echocardiography and confirmed by fluoroscopy and/or transesophageal echocardiography. In 4 patients, both leaflets were involved. No thrombi were visualized. Three patients received thrombolytic therapy in 4 episodes (complete success in 3, partial success in 1) without hemorrhagic or embolic complications. One patient responded to aggressive anticoagulant therapy. One patient required an emergent repeat surgery. In 1 patient, Valve thrombosis recurred thrice. In patients with fair or poor anticoagulation, a bileaflet Valve in the Tricuspid position is associated with a high incidence of Valve thrombosis. Hinge entrapment requires only a small amount of thrombotic material. Valve thrombosis may be asymptomatic. Involvement of both leaflets is usually required to produce symptoms. A nonsurgical approach (thrombolysis or intensified anticoagulation) is usually successful. Patients should be instructed about heralding signs of Valve thrombosis.
