11/242. Penetrating knife injury to the heart.A 39-year-old man attempted to kill himself using a small knife to penetrate the left anterior chest wall because of trouble at work and with his girlfriend. On arrival at the emergency room, his consciousness was not clear and vital signs were unstable. The knife remained vertically located in the left anterior chest wall. A large left hemothorax was identified by chest X-ray, and moderate cardiac tamponade was detected by echocardiography. Left-sided chest drainage was performed by inserting a chest drainage tube, and about 2500 ml of hemorrhagic effusion was drained. An emergency operation was performed to relieve the cardiac tamponade and repair the penetrating cardiac injury. About an hour after arrival at the emergency room, a median sternotomy was performed in the operating room. The knife had injured the surface of the right ventricular outflow tract, the left lung, and the 3rd intercostal artery and vein. cardiopulmonary bypass was immediately prepared for the repair of the cardiac injury. The wounds were successfully repaired with pledgeted sutures under cardiac beating. The postoperative course was uneventful with no sign of infection. The patient was discharged at 9 days after the operation. Here we have reported a case of successful surgical repair of a penetrating knife injury to the heart, which was managed by immediate resuscitation and emergency surgery.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
12/242. life-threatening air rifle injuries to the heart in three boys.air rifles, or BB guns, are generally thought of as childhood toys. Although most injuries are not serious, life-threatening events have been reported. Within a 1-year period, 3 boys presented after BB gun shots to the chest, all requiring surgical intervention for penetrating injuries to the heart. A 15-year-old underwent window pericardiotomy for hemopericardium with thrombus 24 hours after admission. Another, 5 years of age, underwent emergent exclusion of the cardiac apex for a traumatic ventricular septal defect. The third, 8 years old, had a right ventricular injury requiring an urgent subxiphoid pericardial window for tamponade. All recovered uneventfully. Increased public awareness, adult supervision, safety training, and appropriate legislation are needed to decrease the risks of these potentially lethal weapons.- - - - - - - - - - ranking = 0.2keywords = chest (Clic here for more details about this article) |
13/242. Dangerous impact--commotio cordis.Sudden death following blunt chest trauma is a frightening occurrence known as 'commotio cordis' or 'concussion of the heart'. It is speculated that commotio cordis could be caused by ventricular fibrillation secondary to an impact-induced energy that was transmitted via the chest wall to the myocardium during its vulnerable repolarization period. We describe a survivor of commotio cordis caused by a baseball. In this patient, an initial ventricular fibrillation was documented and converted by direct current defibrillation. Serial electrocardiographic changes (bifascicular conduction block and T wave inversion in precordial leads) were noticed in this patient. Our case suggested that coronary vasospasm might also play a role in commotio cordis.- - - - - - - - - - ranking = 0.4keywords = chest (Clic here for more details about this article) |
14/242. Late cardiac arrhythmias after blunt chest trauma.OBJECTIVE: case reports of two patients who developed fatal cardiac arrhythmias several days after blunt chest trauma. DESIGN: case reports. SETTING: Surgical intensive care unit of a university hospital. patients: A 23-year-old man and a 9-year-old girl with blunt chest trauma and multiple further injuries following car crashes were transferred to our institution. Although ECG on admission was normal, both patients developed fatal cardiac arrhythmias after 6 and 4 days, respectively. In both patients, post-mortem analysis confirmed myocardial contusion without coronary artery lesions. Histological findings included severe interstitial oedema, haemorrhages and infiltration of lymphocytes and neutrophils, fresh myocardial necrosis and fatty degeneration. CONCLUSION: Blunt chest trauma with myocardial contusion may lead to fatal cardiac arrhythmias even after several days, particularly when other severe injuries are present. Thus, a normal ECG on admission and absence of cardiac arrhythmias during the first 24 h of intensive care treatment do not necessarily exclude the occurrence of life-threatening arrhythmias in the further course.- - - - - - - - - - ranking = 1.4keywords = chest (Clic here for more details about this article) |
15/242. Forensic echocardiography: a case in point.Transthoracic echocardiography (TTE) has an important role in the assessment of patients with acute penetrating chest trauma. We report the case of a 36-year-old man who sustained a stab wound to the chest. After admission, he required emergency pericardiocentesis. TTE revealed a traumatic ventricular septal defect and a defect in the anterior mitral valve leaflet. To assess whether these lesions were related to the initial stab wound or the pericardiocentesis, the transducer was positioned over the stab wound, and the lesions were shown to be in the same plane as the entry site, thus ruling out iatrogenic trauma.- - - - - - - - - - ranking = 0.4keywords = chest (Clic here for more details about this article) |
16/242. Isolated right atrial tear following blunt chest trauma: report of three cases.Blunt chest trauma causing isolated right atrial tear and cardiac tamponade in three patients is reported. All three patients presented with hypotension, elevated central venous pressure and altered consciousness. Echocardiographic examination demonstrated pericardial effusion in all three cases. All three patients underwent operation with a median sternotomy approach without using cardiopulmonary bypass. At operation, two patients had one tear in the right atrium, the other had two tears in the right atrium. All three patients recovered uneventfully. Early use of echocardiography to detect the presence of hemopericardium and cardiac tamponade in patients with suspected atrial rupture following blunt chest trauma is advocated.- - - - - - - - - - ranking = 1.2keywords = chest (Clic here for more details about this article) |
17/242. rupture of the coronary artery after blunt nonpenetrating chest wall trauma detected by color Doppler echocardiography: a case report.We report a rare case of a ruptured papillary muscle of the anterior leaflet of the tricuspid valve and the rupture of the septal branch of the left anterior descending coronary artery with drainage into the right ventricle after blunt nonpenetrating chest wall trauma. Both abnormalities were detected by transthoracic 2-dimensional and color Doppler echocardiography, and the septal branch rupture was confirmed by coronary angiography. The leading echocardiographic sign of the rupture of the coronary artery was intramyocardial mosaic-colored flow, representing the turbulent high-velocity flow in the ruptured coronary artery. Hypokinesis of the anteroseptal myocardial segments and the presence of Q waves in leads V1 through 4 on the electro-cardiogram were suggestive of anteroseptal myocardial infarction. We conclude that the history of chest trauma, the electrocardiographic changes, and wall motion abnormalities should be stimuli for a careful color Doppler flow "mapping" of the myocardium for possible identification of a coronary artery rupture.- - - - - - - - - - ranking = 1.2keywords = chest (Clic here for more details about this article) |
18/242. Recurrent pericardial chest pain: a case of late right ventricular perforation after implantation of a transvenous active-fixation ICD lead.A 36-year-old woman with a history of recurrent syncopal episodes presumably due to ventricular tachyarrhythmia in mitral valve prolapse underwent implantation of a transvenous ICD system. During a 23-month follow-up, she developed recurrent pericardial chest pain with pericardial friction rub. The first episode of chest pain occurred without any detectable change in pacing or sensing parameters. The second episode was associated with an increase in pacing threshold and drop in intracardiac signal amplitude. Right ventricular perforation was suspected fluoroscopically and confirmed by right ventriculography. This case report emphasizes the key steps in the diagnosis of this rare complication of an ICD implantation.- - - - - - - - - - ranking = 1.2798404870747keywords = chest, chest pain (Clic here for more details about this article) |
19/242. Myocardial contusion presented as acute myocardial infarction after chest trauma.A 46-year-old male patient developed an acute myocardial infarction and congestive heart failure following blunt chest trauma. Electrocardiogram (ECG) revealed acute anterior myocardial infarction. echocardiography showed akinesis of interventricular septum, dyskinesis in apical anterior wall, and severe impairment of left ventricular overall systolic function. coronary angiography revealed normal coronary arteries. The patient followed a low-intensity physical medicine rehabilitation program. Follow-up was without new complications or deterioration of congestive heart failure. Five months later the patient presented with fulminant acute pulmonary edema and cardiogenic shock. cardiopulmonary resuscitation was unsuccessful.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
20/242. Elective removal of an intramyocardial bullet.A 26-year-old man had a gunshot wound in the right posterolateral aspect of the chest. A chest radiograph showed the bullet in the region of the cardiac silhouette. The patient was hemodynamically stable and had no complaints of dyspnea or abdominal pain. echocardiography and computed tomography identified the bullet in the wall of the right ventricle. The surgical management of the injury is discussed in detail.- - - - - - - - - - ranking = 0.4keywords = chest (Clic here for more details about this article) |
