A 25-year-old male presented after a motor vehicle accident with tricuspid valve (TV) regurgitation, due to a flail TV secondary to papillary muscle rupture. We highlight the importance of three-dimensional echocardiographic imaging of the tricuspid valve and its utility in aiding a successful surgical repair.

Increased Risk

A positive seatbelt sign following a motor vehicle accident is associated with an increased risk of intra-abdominal injury and hemoperitoneum. Injury to the uterus in reproductive-age women can also occur. In this report, we describe a 29-year-old nulligravida female who presented to the emergency room following a motor vehicle accident at freeway speeds. A positive seatbelt sign was noted, and a focused assessment with sonography for trauma revealed hemoperitoneum with an incidental finding of uterine leiomyomata. Upon exploratory laparotomy, a free-floating intraperitoneal mass was identified as an avulsed uterine leiomyoma. A uterine laceration containing a subserosal leiomyoma was also identified. The gynecological team was consulted, and a myomectomy of the subserosal leiomyoma followed by a closure of the uterine laceration was performed. The patient was transfused with a total of three units of packed red blood cells and two units of fresh frozen plasma. The postoperative course was without major complication. A positive seatbelt sign and hemoperitoneum in a reproductive-age woman with leiomyomata should increase the clinical suspicion for uterine injury and decrease the threshold for obtaining a gynecological consultation.

A Site

Uterine leiomyomas are the most common gynecological tumors in premenopausal women. While the lung is the most common extrauterine organ afflicted, benign metastasizing leiomyomas (BML) of the heart are rarities. We report an incidental finding of a cardiac mass in a 36-year-old woman who presented to the Emergency Department after a motor vehicle accident. CT scan of the chest revealed 2 well-circumscribed pulmonary nodules and a filling defect in the right ventricle. Echocardiogram showed a 4 cm mass attached to the right ventricular (RV) septum. The cardiac tumor was resected and showed benign histologic features. Immunohistochemical staining was positive for smooth muscle α-actin and desmin, as well as estrogen and progesterone receptors, consistent with the diagnosis of uterine leiomyoma.

Malignant Triton Tumour

A rare case of malignant peripheral nerve sheath tumour with rhabdomyoblastic differentiation (malignant triton tumour) of the anterior mediastinum in a 30-yearold male is reported. The tumour was an incidental finding during the diagnostic work-up following a motor vehicle accident. The patient underwent median sternotomy with a tumour resection performed. Local relapse was suspected one month later, as per the chest CT-scan, and post-operative chemoradiation was applied, which produced a response. Twelve months later the patient is doing well while radiological findings remain invariable. Localization of a triton tumour in the anterior mediastinum is extremely rare, adjuvant treatment is necessary, recurrence frequently occurs and the prognosis is dismal.

Abstract:Bayesian inferencing as a machine learning technique was evaluated for identifying pre-crash activity and crash type from accident narratives describing 3,686 motor vehicle crashes. It was hypothesized that a Bayesian model could learn from a computer search for 63 keywords related to accident categories. Learning was described in terms of the ability to accurately classify previously unclassifiable narratives not containing the original keywords. When narratives contained keywords, the results obtained using both the Bayesian model and keyword search corresponded closely to expert ratings (P(detection)≥0.9, and P(false positive)≤0.05). For narratives not containing keywords, when the threshold used by the Bayesian model was varied between p>0.5 and p>0.9, the overall probability of detecting a category assigned by the expert varied between 67% and 12%. False positives correspondingly varied between 32% and 3%. These latter results demonstrated that the Bayesian system learned from the results of the keyword searches.

Pseudo-endocarditis secondary to ruptured posteromedial papillary muscle with anatomical variation: A Case Report

Mitral Valve Vegetation

Myocardial infarction is the leading cause of papillary muscle rupture. This complication occurs in up to 5% of cases post MI and although rare, it constitutes a cardiac emergency if left untreated. On this basis, a 59-year-old male presented with low-grade fever and atypical chest pain with raised inflammatory markers and troponin levels. He was treated for infective endocarditis after echocardiography revealed a mass on the mitral valve, which was presumed to be a mitral valve vegetation and so he completed a 6-weeks course of antibiotics followed by elective mitral valve replacement surgery. During surgery, it was discovered that there was no endocarditis. Instead an unusually small muscle head of one of the posteromedial papillary muscle groups had ruptured secondary to an inferior myocardial infarction. This ruptured muscle head was highly mobile and mimicked a mitral valve vegetation. The mitral valve was successfully repaired, and the right coronary artery grafted. He made a full recovery but developed new-onset atrial fibrillation for which he is awaiting elective cardioversion. One should have a high index of suspicion for diagnosing papillary muscle rupture as it may mimic valvular vegetation on echocardiography, especially if the papillary muscle involved is an anatomical variant.
