Isolated left ventricular non-compaction is the result of incomplete myocardial morphogenesis, leading to persistence of the embryonic myocardium. The condition is recognised by an excessively prominent trabecular meshwork and deep intertrabecular recesses of the left ventricle. These intertrabecular recesses are prone to thrombus formation, with resultant embolic sequelae. We describe ...

Primary cardiac angiosarcoma is a rare tumor associated with a poor prognosis. We report a case of a 59-year-old woman with right atrial angiosarcoma presenting with cardiac tamponade due to right atrial perforation. She underwent urgent surgical resection of the tumor. However, the patient died 68 days after surgery due ...

Acute coronary syndrome (ACS) comprises different manifestations of coronary artery disease. Angiograms performed at the time of an ACS may present different coronary morphologies; mostly there are acute vessel occlusions, ruptured atherosclerotic plaques, or thrombotic lesions that require reperfusion therapy. In the presence of intracoronary thrombi localized in the left ...

This is a case series on three adult patients who contain left ventricular (LV) thrombus and the incremental benefits of live/real time three-dimensional transthoracic echocardiography (3DTTE) in comparison to two-dimensional transthoracic echocardiography (2DTTE) in evaluating LV thrombi. These cases illustrate that 3DTTE is of additional benefit by demonstrating the following: ...

Primary cardiac sarcomas are rare. In such tumors, surgical resection is sometimes considered necessary to correct obstruction of flow caused by the tumor and to accomplish complete resection. The anatomic difficulties associated with large, primary, intracavitary left-sided sarcomas have led us to use cardiac explantation, ex vivo tumor resection, and ...

Transesophageal echocardiography (TEE) is commonly performed to detect the presence of a left atrial appendage (LAA) thrombus in the setting of an embolic event or before an anticipated electrical cardioversion for atrial fibrillation. The predictive value of transthoracic echocardiographic (TTE) findings in these patients has not been well defined. This ...

"No-reflow" is an important complication of percutaneous coronary intervention (PCI) in the setting of acute myocardial infarction and is associated with worse outcomes. Visible thrombus on the angiogram is a significant risk factor for "no-reflow". A variety of strategies have been employed to prevent this phenomenon including intracoronary vasodilators and ...

The rapid closure of coronary arteries due to occlusive thrombi is the major cause of acute myocardial infarction. However, the mechanisms of coronary thrombus formation have not been elucidated. We immunohistochemically assessed the localizations and their changes over time of glycoprotein IIb/IIIa, fibrin, von Willebrand factor (vWF), and tissue factor ...

Formation of intracoronary thrombus during percutaneous coronary intervention can lead to acute vessel closure and myocardial infarction if prompt action is not taken. Thrombus removal using mechanical thrombectomy is the common treatment approach. We report a rare case of thrombus formation immediately after guidewire advancement, causing acute myocardial ischemia. Intracoronary ...

A mobile and pedunculated left ventricular thrombus developed after acute myocarditis in a 49-year-old woman. Surgical removal is recommended for cases such as this, especially when the ventricular thrombus is pedunculated or mobile. The thrombus was successfully removed by left atriotomy. There was no evidence of recurrent thrombus formation on ...

BACKGROUND: Minimally invasive surgery is pervading all fields of surgery with the principal benefits being: reduced pain, smaller incision, faster recovery, shorter hospital stay and reduced cost. Cardiac surgery is no different. Cardiac myxoma morbidity and mortality depends on early diagnosis, adequate exposure, complete resection, minimal manipulation and unifocal presence. ...

Mitral stenosis associated with free left atrial myxoma is very rare. A free myxoma is life-threatening when incarcerated in the mitral orifice or if embolization of the whole tumor occurs. We report a case of a female patient with moderate mitral stenosis and a detached left atrial myxoma. The myxoma ...

Familial cardiac myxoma is inherited as an autosomal dominant syndrome. Here, we report a Japanese case of familial cardiac myxoma identified as a genetic abnormality. The mother experienced multiple recurrence of tumors in the left atrium and left ventricle 40 months after surgical resection of a left atrial myxoma. All ...
Braun S - - 2005
Although cardiac myxomas are histologically benign, they tend to form emboli and cause intracardiac obstruction, so that they must be classified as potentially fatal tumors of the heart. The probability of arterial embolism is closely correlated with the morphology of the tumor. Thus, villous myxomas are more fragile and form ...

A 46-year-old female was admitted to our hospital complaining of dizziness. Echocardiography and magnetic resonance imaging showed a pedicled tumor in the right ventricular outflow tract (RVOT), causing severe obstruction during systole. Resection was performed under cardiopulmonary bypass. Postoperative course was uneventful, with complete disappearance of major symptoms. Histological examination ...

Right atrial myxomas are rare intracardiac tumors that often pose difficulties in diagnosis. Right ventricular failure and ascites ensuing from tricuspid valve orifice obstruction are potentially dangerous complications. Early diagnosis of cardiac myxoma is important since surgical treatment leads to disappearance of all symptoms with a low rate of recurrence ...

Coronary air embolism remains a recognised complication of coronary catheterisation despite a strong emphasis on prevention. Current treatment consists of supportive measures with 100% oxygen and analgesia. Recent case reports describe the use of mechanical treatments aimed at dispersing or removing the air embolus with variable success. A case of ...
