چکیده

Cardiac chamber rupture in blunt trauma is uncommon and is associated with a high mortality rate. We report a patient involved in a motor vehicle collision with an isolated right atrial injury resulting in a pericardial effusion associated with hemodynamic compromise. A 20 year-old intoxicated female was transported after sustaining a collision in her vehicle. The patient remained mildly hypotensive and tachycardic despite volume resuscitation. FAST was negative showing good cardiac motion and no fluid in her abdomen. A CT scan revealed a mediastinal hematoma and free intra-abdominal fluid, and trans-thoracic echocardiogram (TTE) identified a mass within the right atrium associated with a pericardial effusion. In the operating room, clot was removed from within the pericardium. Hypothermic circulatory arrest and cardiopulmonary bypass were performed and a single laceration involving the right atrium was repaired after removing a large intra-atrial clot. A negative concurrent exploratory laparotomy was performed. The patient was discharged from the hospital postoperative day 6. This report presents an isolated right atrial tear associated with pericardial tamponade following blunt trauma and we discuss the role of early diagnosis and treatment.

Right Atrium Laceration with Pericardial Tamponade: A Rare Presentation of Blunt Cardiac Trauma

Cardiac laceration from blunt thoracic trauma is not a common presentation. The rate of mortality due to this injury is very high since it is not diagnosed and treated immediately. In this study, we present the case of a 65-year-old man with blunt cardiac trauma, causing right atrial rupture and pericardial tamponade. Successful management of this patient was firstly done with initial pericardi...

Isolated right atrial appendage (RAA) rupture in blunt trauma – a case report and an anatomic study comparing RAA and right atrium (RA) wall thickness

BACKGROUND Heart chambers rupture in blunt trauma is uncommon and is associated with a high mortality. The determinant factors, and the incidence of isolated heart chambers rupture remains undetermined. Isolated rupture of the right atrium appendage (RAA) is very rare, with 8 cases reported in the reviewed literature. The thin wall of the RAA has been presumed to render this chamber more prone ...

Blunt cardiac injury: case report of salvaged traumatic right atrial rupture.

The incidence of cardiac rupture following blunt trauma is rare, occurring in 0.3%-0.5% of all blunt trauma patients. It can be fatal at the trauma scene, and is frequently missed in the emergency room setting. The severity of a cardiac trauma is based on the mechanism and degree of the force applied. The objective of this study was to report the case of a 32-year-old male patient who was invol...
