1/9. Tricuspid dura mater bioprostheses: more than 20-year follow-up of 3 patients.Replacement of the tricuspid valve is sometimes necessary. We report 3 consecutive patients with tricuspid insufficiency who underwent valve replacement with glycerol-preserved, homologous dura mater cardiac bioprostheses between 1971 and 1973. The first 2 patients are well 28 and 27 years later; the last patient was lost to follow-up after 20 years. We conclude that preservation of homologous dura mater bioprostheses in glycerol may reduce rates of thromboembolism, thrombosis, and structural dysfunction during the late postoperative period.- - - - - - - - - - ranking = 1keywords = thromboembolism (Clic here for more details about this article) |
2/9. Unexpected mechanical bileaflet valve thrombosis in mitral position: what is better to do, re-replacement or thrombolysis.BACKGROUND AND AIMS: The longevity of the mechanical heart valve prosthesis is an advantage when compared with its biological counterpart, although the former carries a risk of thrombosis depending on valve design, materials and host-related interface; therefore, a patient with a mechanical valve prosthesis, particularly in mitral position, is at risk for systemic thromboembolism even when properly anticoagulated. patients AND methods: We report a case of a 60-year-old woman who underwent a mitral valve replacement with a St. Jude Medical (SJM) standard bileaflet mechanical heart valve. RESULTS: On the twelfth post-operative day a primary thrombosis with blockage of the anterior valve leaflet occurred. CONCLUSIONS: Aware of the risk of recurrent thromboembolism in this special clinical framework and possible cerebral bleeding in case of thrombolysis, we replaced the prosthesis with a new biologic porcine valve, the SJM Biocor.- - - - - - - - - - ranking = 2keywords = thromboembolism (Clic here for more details about this article) |
3/9. thromboembolism associated with pigtail catheters.Three incidents of asymptomatic arterial thromboembolism associated with polyurethane pigtail catheters occurred during 1,417 cases of left ventricular angiocardiography. No similar incident occurred with polyethylene pigtail or (dacron) Eppendorf and Gensini (style) catheters. in vitro comparison of hydraulic characteristics of polyurethane (Cordis) and polyethylene (Cook) pigtail catheters showed higher flow-pressure transmission through the tip of the Cordis polyurethane catheter favoring dislodgment of any existing clot. The problem of thrombogencity of polyethylene compared with polyurethane remains unsettled. Our experience with polyurethane pigtail catheters has resulted in limitation of their use in our laboratory.- - - - - - - - - - ranking = 1keywords = thromboembolism (Clic here for more details about this article) |
4/9. Left ventricular mobile thrombus associated with ventricular assist device: diagnosis by transesophageal echocardiography.Ventricular assist devices (VADs) have been used as a bridge to cardiac transplantation in patients with end-stage congestive heart failure. Despite adequate anticoagulation, thromboembolism is a major complication and in particular, a left ventricular (LV) thrombus associated with VADs has been reported as an important cause of thromboembolic complications. The frequency of LV thrombus formation in the patients with VAD support using LV apical cannulation is reported to be low. A 61-year-old woman supported with VAD with LV apical cannulation had a mobile LV thrombus adjacent to the inflow cannula diagnosed by transesophageal echocardiography.- - - - - - - - - - ranking = 1keywords = thromboembolism (Clic here for more details about this article) |
5/9. A case of vasospastic angina resulting from coronary emboli in a patient with prosthetic valves.In addition to coronary atherosclerotic disease, coronary thromboembolism can also lead to acute coronary syndromes. However, coronary thromboembolism due to prosthetic heart valves is very rare and not very well-known. It have been reported only a few cases. In this paper, we present a rare case with vasospastic angina pectoris secondary to coronary thromboembolism in a patient with prosthetic heart valves.- - - - - - - - - - ranking = 3keywords = thromboembolism (Clic here for more details about this article) |
6/9. Management of left atrial endocardium after extensive thrombectomy.thrombosis at the left atrium is a common phenomenon in patients with chronic mitral valve disease and atrial fibrillation. When thrombus organizes and evolves into chronic phase, clean thrombectomy can become a challenge during heart surgery because of dense adhesions and the lack of clean cleavage plane. Leaving residual thrombotic material or roughened endocardial surface after thrombectomy could be a potential source for further thrombosis and a nidus for thromboembolism. We recently managed such a patient successfully using extensive thrombectomy and endocardial coverage with a fresh autologous pericardial patch.- - - - - - - - - - ranking = 1keywords = thromboembolism (Clic here for more details about this article) |

We report a case of acute abdominal aortic occlusion due to rheumatic mitral stenosis, in the absence of atrial fibrillation, mimicking spinal cord compression. Systemic streptokinase given 48 hours after symptom's onset lead to rapid and dramatic recovery with limb salvage.- - - - - - - - - - ranking = 1keywords = thromboembolism (Clic here for more details about this article) |

9/9. Bacterial invasion of pulmonary vessels. Pseudomonas bacteremia mimicking pulmonary thromboembolism with infarction.pseudomonas aeruginosa displays a curious propensity for invading blood vessels and causing vessel wall necrosis. This bacteremia-related "vasculitis" is often associated with hemorrhagic necrosis and infarction of surrounding organ parenchyma. With the exception of skin lesions, however, clinical manifestations of Ps. aeruginosa vasculitis seldom occur. In the patient we describe, fatal Ps. aeruginosa bacteremia was first manifested by a syndrome indistinguishable from pulmonary thromboembolism with infarction.- - - - - - - - - - ranking = 5keywords = thromboembolism (Clic here for more details about this article) |
