ABSTRACT
Sternal fractures caused by blunt chest trauma are associated with an increased incidence of cardiac injury. Reports of the incidence of cardiac injury associated with sternal fracture range from 18% to 62%. Delayed cardiac tamponade is a rare phenomenon that appears days or weeks after injury. Moreover, after nonpenetrating chest trauma, cardiac tamponade is very rare and occurs in less than 1 of 1000. This case describes a patient who had delayed cardiac tamponade 17 days after a severe blunt chest trauma.

BACKGROUND: International normalized ratio (INR) self-testing can improve the management of anticoagulation therapy with warfarin for the patients following mechanical heart valve replacement. Several reviews and studies have demonstrated self-management as an option to improve patient's outcome considerably after mechanical heart valve replacement. We sought to analyze the security, economy and discuss the prospect of self-testing of anticoagulation therapy in patients following mechanical heart valve replacement in China, and evaluate the accuracy and stability of CoaguChek XS portable INR-testing device. METHODS: This was a prospective self-controlled clinical study conducted with 526 patients receiving oral warfarin anticoagulation therapy after mechanical heart valve replacement in the period of Mar.1, 2012 - Nov.1, 2012 in Cardiovascular Surgery Department of West China Hospital of Sichuan University. The same patient performed INR testing with CoaguChek XS portable coagulometer (group1) and central lab (group 2) in parallel. The follow-up time was 6 months. Meanwhile, a questionnaire was handed out to survey the expenses required for the re-examination visits to the hospital, time, and anticoagulation complications. RESULTS: No severe anticoagulation complications occurred in all the patients. No significant difference of the INR results were observed between group 1 and group 2, they showed significant relevance, r = 0.953(p < 0.05). Compared with the conventional method of INR testing in hospital, the portable coagulometer is convenient, quick and less traumatic. Self-testing of anticoagulation therapy reduced the cost and the time required for re-examination. CONCLUSIONS: Results of CoaguChek XS monitor are precise and have a good consistency and stability as compared with traditional laboratory testing. For the patients receiving anticoagulation therapy after mechanical heart valve replacement, the self-testing of anticoagulation therapy with portable coagulometer is a safe choice, and it has a promising future application in China.

We presented an unique case of portal vein thrombosis (PVT) after aortic valve replacement due to antithrombin III (ATIII) deficiency. PVT after aortic valve replacement (AVR) is a serious complication, which has not previously been reported.
