BACKGROUND Primary cardiac tumors are infrequent, and few cardiac surgeons have extensive experience in treating them. The majority of the tumors are benign. As noninvasive diagnostic imaging of cardiac masses continues to improve, the number of these tumors that are seen by clinicians will increase. More of the malignant tumors may be curable if detected(More)
OBJECTIVE To analyze the factors affecting outcome in patients with blunt cardiac rupture, including anatomical cardiac injury, associated injury, clinical presentation, age, mechanism of injury, diagnostic method, surgical intervention, and presence of vital signs in the field and on arrival. DESIGN Retrospective review. SETTING A community-based level(More)
BACKGROUND The purpose of this study was 3-fold: to compare the quality of life (QOL) in age- and sex-matched patients who received biological and mechanical prosthetic valves in isolated aortic valve replacement, to compare the QOL of patients with aortic valve replacement with the general population, and to compare patients with biological and mechanical(More)
BACKGROUND Patients who have massive but potentially survivable injuries frequently die from complications of hypovolemia, hypoxemia, hypothermia, metabolic acidosis, and coagulopathy. Emergency cardiopulmonary bypass has been unsuccessful in preventing such deaths because it involves systemic anticoagulation that exacerbates coagulopathy. PATIENTS AND(More)
Tracheobronchial tree injuries occur in a small number of patients after blunt chest trauma, and their occurrence is even more uncommon in the pediatric trauma population. The authors present the case of a 2-year-old boy who presented with rupture of the trachea and disruption of the right upper lobe bronchus and bronchus intermedius.
Two elderly patients, involved in separate motor vehicle accidents, sustained blunt chest injury resulting in rupture of their thoracic aortas. The initial chest radiographs showed the presence of a calcified ring fractured in two places with lateral displacement of a calcified fragment by haematoma. This 'broken halo sign' is a radiographic sign not(More)
