This report presents three patients with severe pulmonary hypertension secondary to atrial septal defect associated with thrombus and spontaneous echo contrast within the pulmonary artery diagnosed by transthoracic and transoesophageal echocardiography. Clinical and echocardiographic features seem to suggest local thrombus formation within the pulmonary arteries as a direct consequence of pulmo...

UNLABELLED Right atrial appendage aneurysms (RAAAs) are rarely encountered. If symptomatic, they present with atrial arrhythmias or embolic events. Surgical resection is indicated for symptomatic patients. We describe a 65-year-old man presenting with palpitation for 6 months. Electrocardiogram showed atrial flutter. Transthoracic echocardiography revealed a large thin-walled cystic mass anteri...

BACKGROUND The correlation between normal cardiac chamber linear dimensions measured during retrospective coronary computed tomographic angiography as compared to transthoracic echocardiography using the American Society of Echocardiography guidelines is not well established. METHODS We performed a review from January 2005 to July 2011 to identify subjects with retrospective electrocardiogram...

Background Diastolic function is almost exclusively assessed using transthoracic echocardiography (TTE), however velocityencoded phase-contrast imaging permits diastolic evaluation with cardiac magnetic resonance (CMR). However, previous studies have utilized heterogeneous planimetric contour locations to measure mitral valve (MV) inflow velocities and the optimal contour is uncertain. We there...

Method For investigation of her complaints transthoracic echocardiography, thoracoabdominal computerized tomography with contrast and coronary angiography combined with thoracic aortography revealed an aortic aneurysm with 55 mm in diameter, beginning 4 cm distally from aortic root and ending prior to arc of aorta. Surgical intervention was planned in Cardiology and Cardiovascular surgery counc...

Extract: A 28-year-old asymptomatic woman was referred to ourclinic for evaluation of a heart murmur. Transthoracic echocardiography (TTE) demonstrated ventricular hypertrophy with septal thickness of 26 mm., consistent with hypertrophic cardiomyopathy (HCM). The diagnosis of HCM was confirmed by contrast-enhanced magnetic resonance imaging, and late gadolinium enhancement was observed in the a...

A subaortic membrane is an uncommon cause for left ventricular outflow tract obstruction. Hypertrophic cardiomyopathy with dynamic left ventricular outflow tract obstruction would mask the presence of the subaortic membrane on transthoracic echocardiography and cause a false diagnosis. We report a patient with subaortic stenosis due to flail subaortic membrane misdiagnosed as obstructive hypert...

Aims: Secondary cardiac tumours are rare conditions, often difficult to suspect. We aim to describe the diagnostic potential of transthoracic and transesophageal echocardiography in this field, and to discuss their reliability as modalities of choice for preoperative diagnosis. Methods and Results: We used several complementary diagnostic approaches: Color-Doppler transthoracic echocardiography...
