Cardiac trauma has been recognized as a complication associated with blunt chest trauma involving coronary artery injury, myocardium contusion and myocardial rupture. Secondary cardiac injuries after trauma supposed to be a critical factor in trauma patients, but the mechanism is not fully explored. Overproduction of TNF-alpha had been reported in multiple trauma animals, this induces oxidative stress resulting in cardiac apoptosis. Apoptosis gradually increases after trauma and reaches to a maximum level in 12 h time...

We report a contained rupture of a right coronary sinus of Valsalva aneurysm, in which repair resulted in symptomatic improvement. Patients often present with symptoms secondary to rupture of the sinus of Valsalva aneurysm into one of the cardiac chambers, or secondary to the compression of adjacent structures. Whereas sinus of Valsalva aneurysms and their rupture are well reported in the literature, contained ruptures have been described only rarely. In those cases, symptoms often arose from compression of adjacent structures...

We have reported that the Toll-like receptor 9 (TLR9) signaling pathway plays an important role in the development of pressure overload-induced inflammatory responses and heart failure. However, its role in cardiac remodeling after myocardial infarction has not been elucidated.TLR9-deficient and control C57Bl/6 wild-type mice were subjected to left coronary artery ligation. The survival rate 14 days post-operation was significantly lower in TLR9-deficient mice than that in wild-type mice with evidence of cardiac rupture in all dead mice...

Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography...

For patients who survive the initial bleeding event of a ruptured brain aneurysm, delayed cerebral ischemia (DCI) is one of the most important causes of mortality and poor neurological outcome. New insights in the last decade have led to an important paradigm shift in the understanding of DCI pathogenesis. Large-vessel cerebral vasospasm has been challenged as the sole causal mechanism; new hypotheses now focus on the early brain injury, microcirculatory dysfunction, impaired autoregulation, and spreading depolarization...

A pseudoaneurysm refers to a defect in the arterial wall, allowing communication of arterial blood with the adjacent extra-luminal space. Pseudoaneurysms result from traumatic arterial injury. With the increasing utilization of percutaneous arterial interventions, iatrogenic arterial injury has become the predominant cause of pseudoaneurysm formation. Rupture of the pseudoaneurysm comprises a vascular emergency. Clinical suspicion and imaging techniques are the cornerstones of timely diagnosis and appropriate management of the condition...

Classical "Windsock deformity" is associated with ruptured aneurysmal sinus of Valsalva. The echocardiographic definition for Atrial septal aneurysm (ASA) in children based on dimensions is lacking. Rupture of an ASA, though uncommon, may lead to cardiac failure due to acute RV volume overload. An untreated ASA may be complicated with thrombus formation.

Left ventricular aneurysm (LVA) and false aneurysm are complications of acute myocardial infarction, trauma, and cardiac surgery. Left ventricular false aneurysm (LVFA) is a particularly catastrophic complication owing to its high propensity for rupture. Surgical resection should be considered for LVFA occurring within three months after myocardial infarction or development of congestive heart failure. In this report, we describe a case of acute heart failure with LVA and LVFA occurring in stage as a complication of myocardial infarction in a 55-year-old man...

Autopsy imaging (Ai), postmortem imaging before necropsy, is used in human forensic medicine. Ai was performed using computed tomography (CT) for a 1-month-old Thoroughbred foal cadaver found in a pasture. CT revealed pericardial effusion, collapse of the aorta, bleeding in the lung lobe, gas in the ventricles and liver parenchyma, and distension of the digestive tract. Rupture in the left auricle was confirmed by necropsy; however, it was not depicted on CT. Therefore, Ai and conventional necropsy are considered to complement each other...

Motor vehicle accident is the most common cause of blunt cardiac injury (BCI) in children (85.3%) due to the height of the child in relation to proper restraints and the compliant pediatric rib cage (J Trauma. 1996;40:200-202). Trauma to the chest wall may lead to injury of the myocardium, resulting in myocardial contusion, ventricular septal defect (VSD), ventricular free wall rupture, or valve compromise (J Trauma. 1996;40; 200-202; Heart Lung. 2012;41:200-202; J Inj Violence Res. 2012;4:98-100). There are several proposed mechanisms for the formation of VSD after blunt chest trauma including rupture of ischemic myocardium related to the initial trauma and reopening of a spontaneously closed congenital VSD...

BACKGROUND: Bicuspid aortic valve (BAV), the most frequent congenital cardiac abnormality, is associated with a higher risk for ascending aortic aneurysms and aorta-related complications (ie, dissection and rupture). The aim of this study was to quantify granular media calcinosis (GMC) in the ascending aortic wall of patients with BAV. METHODS: We analyzed samples of the ascending aorta from patients with BAV (n = 54) and patients with tricuspid aortic valve (TAV) (n = 33) who underwent aortic repair, regarding medial thickness and diameter expansion...

BACKGROUND: Cardiac rupture often occurs after myocardial infarction or chest trauma with a high mortality rate. However, left ventricular rupture caused by radiofrequency catheter ablation (RFCA) is extremely rare. METHODS: We describe a case of a 61-year-old male who survived from left ventricular rupture caused by a RFCA procedure for frequent ventricular premature contractions. Surgical exploration with cardiopulmonary bypass (CPB) was performed when the signs of cardiac tamponade developed 7 hours after the ablation surgery...

We describe an adult female presenting with dyspnea in whom both transthoracic and transesophageal echocardiography detected a mobile sac-like structure in the right ventricular outflow tract (RVOT) containing a heterogenous echogenic mass. This sac-like structure markedly changed its shape and size during the cardiac cycle. These findings and the fact that the patient lived in a rural area raised the possibility that this was a hydatid cyst. A bubble study using normal saline was useful in detecting a contained rupture of the cyst...

A patient who underwent previous implantation of a mitral valve replacement with a Björk-Shiley Delrin (BSD) mitral valve prosthesis during infancy was admitted to our institution 43 years later after an episode of syncope and cardiac arrest. Under extreme hemodynamic instability, a mitral valve prosthetic dysfunction causing massive mitral regurgitation was identified. The patient underwent an emergent cardiac operation, and a complete disc fracture with partial disc migration was found. Exceptional cases of mechanical prosthetic heart valve fracture exist...

Aortic mycotic aneurysms are a rare but life-threatening potential complication of infective endocarditis. Rapid deterioration of the vascular wall in highly focal areas makes these pseudoaneurysms particularly prone to rupture, resulting in uncontrolled aortic hemorrhage. While computed tomography angiography (CTA) is the imaging modality of choice for the evaluation of mycotic aneurysms, it is not routinely performed in patients with known or suspected infective endocarditis (IE). However, current valvular heart disease guidelines support the use of cardiac CTA in cases of IE and suspected perivalvular extension when there is inadequate or ambiguous visualization on echocardiography...

Cardiovascular complications, particularly perioperative myocardial infarction (PMI), are major contributors to mortaliyt after noncardiac surgery. PMI often occurs unnoticed without symptoms or ECG changes. Despite ist silent presentation, PMI is associated with increased mortality. The combination of high associated mortality and diagnostic challenges mandates increased awareness of PMI. Perioperative myocardial infarction may result from plaque rupture (PMI type I) or be caused by a myocardial supply-demand imbalance of oxygen without plaque rupture (PMI type II)...
