1/34. A large false aneurysm of the right ventricle within a giant epicardial lipoma.Lipomas, which account for approximately 10% of all neoplasms of the heart, may be detected in asymptomatic patients by chance during echocardiography, CT scan, or MRI scan. Occasionally, lipomas are complicated by arrhythmias. We describe a patient who presented with severe cardiomegaly and paroxysmal supraventricular tachycardia. An MRI scan showed a large intrapericardial lipoma with two large cavities inside communicating with each other and with the right ventricular chamber through a defect of the right ventricular wall. The mass was partially removed, and the right ventricle was patched. Surgery combined with antiarrhythmic therapy resulted in a good short-term result.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/34. Congenital giant aneurysm of the left atrial appendage mimicking pericardial absence case report.A 25-year-old man was found to have an abnormal cardiac contour on a chest radiograph, and was referred. Transesophageal echocardiography suggested herniation of the left atrial appendage (LAA) through a gap in the pericardium, and magnetic resonance imaging indicated congenital partial absence of the pericardium. Cardiac dysfunction was caused by compression from the enlarged left atrium and thrombi were thought to be present in the appendage, so surgery was performed. The intraoperative diagnosis was congenital LAA aneurysm. Although distinguishing between congenital LAA aneurysm and congenital absence of the pericardium is reported to be possible with magnetic resonance imaging, we were unable to so in this case.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/34. Giant left atrial intrapericardial aneurysm: noninvasive preoperative imaging.Congenital giant intrapericardial aneurysms of the left atrium are rare. A 17-year-old boy presented with paroxysmal episodes of palpitations, chest pain, and dyspnea. A chest roentgenogram showed an enlarged left cardiac silhouette. Transthoracic echocardiography imaging showed an intrapericardial aneurysm of the left atrium. Cardiac magnetic resonance imaging confirmed the diagnosis and delineated adjacent structures to plan the surgical resection. We have found no previous reports of cases of diagnosis and preoperative assessment based solely on noninvasive imaging.- - - - - - - - - - ranking = 0.25keywords = giant (Clic here for more details about this article) |
4/34. Aneurysmal dilation of a pericardial patch prepared with glutharaldehyde and used for closure of a ventricular septal defect.pericardium patches are commonly used for the repair of congenital heart diseases. Aneurysmal dilation is a complication specific to the use of pericardial patches. Preparation of the pericardium with glutharaldehyde is considered to avoid this risk. In the present case report, we describe the development of a giant aneurysm of a heterologous patch used for closure of a ventricular septal defect in a child aged 14 days.- - - - - - - - - - ranking = 0.25keywords = giant (Clic here for more details about this article) |
5/34. Left ventricular apical aneurysm in cardiac sarcoidosis.A 53-year-old woman was hospitalized for general fatigue and palpitations. An electrocardiogram showed ST elevation and T wave inversion in leads II, III, aVF, and V4-6. cardiac catheterization was performed since the echocardiogram demonstrated the existence of a left ventricular apical aneurysm. Left ventriculography showed an aneurysm of the apex. An endomyocardial biopsy specimen from the left ventricular apical wall demonstrated typical noncaseating granulomas with giant cells. The patient was diagnosed as having cardiac sarcoidosis. There was no evidence suggesting involvement of other systemic organs. Cardiac sarcoidosis should be considered within a spectrum of diseases that cause left ventricular aneurysm.- - - - - - - - - - ranking = 0.25keywords = giant (Clic here for more details about this article) |
6/34. mitral valve replacement and endocavitary patch repair for a giant left ventricular pseudoaneurysm.We present a case of a giant inferior left ventricular (LV) wall pseudoaneurysm. The patient had new york Heart association class IV heart failure due to severe mitral valve regurgitation and poor LV function. Our operative approach included right thoracotomy, excision of the mitral valve, and patch repair of the pseudoaneurysm neck from inside of the dilated LV cavity followed by mitral valve replacement. Surgery was performed without aortic cross-clamping on a normothermic perfused beating heart. The patient had an uncomplicated cardiac recovery and is doing well 15 months after surgery.- - - - - - - - - - ranking = 1.25keywords = giant (Clic here for more details about this article) |
7/34. Dor's endoaneurysmorrhaphy in severe heart failure due to giant cell myocarditis.Giant cell myocarditis is an unusual and frequently fatal form of myocarditis. A 37-year-old woman presented with resistant cardiac failure and left ventricular aneurysm. She underwent Dor's endoaneurymorrhaphy and was histopathologically proved to have giant cell myocarditis. She had significant improvement of symptoms and was alive 13 months after surgery. Dor's endoaneurysmorrhaphy may be a useful therapeutic modality in selected cases of giant cell myocarditis.- - - - - - - - - - ranking = 1.5keywords = giant (Clic here for more details about this article) |
8/34. Asymptomatic giant right atrial aneurysm.A 5-year-old asymptomatic boy was found incidentally, on a chest radiograph, to have gross cardiomegaly; further evaluation by echocardiography showed a giant right atrial aneurysm. The patient underwent successful surgical reduction of the right atrium, closure of an atrial septal defect, and tricuspid valve repair These measures were taken to prevent thrombus formation in the right atrium, prevent paradoxical embolism, and lower the risk of atrial arrhythmias. The morphologic features of the resected atrial tissue showed paper-thin wall with a central aneurysm and focal endocardial fibrosis consistent with a diagnosis of idiopathic dilatation of the right atrium.- - - - - - - - - - ranking = 1.25keywords = giant (Clic here for more details about this article) |
9/34. Giant aneurysm of the membranous ventricular septum extending outside the heart: diagnosis by transthoracic color flow Doppler echocardiography.aneurysm of the membranous ventricular septum (AMS) is a congenital cardiac anomaly often associated with ventricular septal defect. This aneurysm usually pouches into the right side of the heart and remains intracardiac. An AMS that extends outside of the heart is rare. We report an unusual case of a giant extracardiac AMS diagnosed by transthoracic color flow Doppler echocardiography.- - - - - - - - - - ranking = 0.25keywords = giant (Clic here for more details about this article) |
10/34. Accidental detection of a giant right atrial aneurysm in an asymptomatic infant.We present a 4-month old infant boy accidentally detected to have cardiomegaly on a chest radiograph, and on further investigation discovered to have a giant right atrial aneurysm and a secundum atrial septal defect. Congenital right atrial aneurysm or diverticulum is a rare anomaly, usually presenting with atrial or supraventricular tachycardia. Previously reported patients did not have any associated congenital heart defect. Although asymptomatic our patient needs close follow-up, and surgical resettion of the aneurysm and closure of the atrial septal defect in view of potential complications.- - - - - - - - - - ranking = 1.25keywords = giant (Clic here for more details about this article) |
