Primary cardiac tumours are quite rare and most of these tumours are benign. In this report, a patient presented with heart failure symptoms attributable to severe mitral valve stenosis. Echocardiography showed a dense left atrial mass causing functional mitral valve obstruction. The morphological and intraoperative presentation was highly suggestive of a myxoma but histopathological examinatio...
Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, inc...
Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization. The most common sites of origin are aortic and mitral valve surfaces. We present successful surgical resection of a papillary fibroelastoma through the...
Two-dimensional echocardiography revealed cardiac tumors in the fetus of a mother with tuberous sclerosis. After birth, six cardiac tumors were demonstrated by two-dimensional echocardiography. Real-time three-dimensional echocardiography was performed, which demonstrated good cardiac wall motility. Data set analysis revealed a 7 tumor adjacent to the aortic valve: normal aortic valve movements...
soon after cardiac transplantation, but the recipient patients seldom show a postoperative precordial murmur attributable to valve dysfunction. This is not surprising, because mild forms of valvular regurgitation detected by Doppler are often clinically inaudiblee5 Overt signs of tricuspid regurgitation and right ventricular failure were observed in 2 patients with residual postoperative pulmon...
acute dissection or the ascending aorta requires immediate surgical intervention. without surgical treatment ii:i,) of the patients will die every hour. in this study we report the result ofoperations on patients with stanford type a aortic dissection. from 1997 to 2003. 26 patients (16 males, 10 females) aged 30 to 71 years (mean age 4~.9 :i: 2.3 years) underwent surgical treatment. in all of ...
Quadricuspid aortic valve is a rare congenital heart defect. The authors present a case of this anomaly in a young, asymptomatic adolescent who presented to the echocardiography laboratory for further evaluation of a cardiac murmur detected on routine physical examination. Imaging revealed a quadricuspid aortic valve with aortic regurgitation. This case highlights the importance of auscultation...
BACKGROUND The significance of right ventricular ejection fraction (RVEF), independent of left ventricular ejection fraction (LVEF), following isolated coronary artery bypass grafting (CABG) and valve procedures remains unknown. The aim of this study is to examine the significance of abnormal RVEF by cardiac magnetic resonance (CMR), independent of LVEF in predicting outcomes of patients underg...
Despite increasing trends in catheter-based cardiac surgical procedures, more than 278 000 Americans had traditional cardiac surgery in 2013. Of those surgical procedures, approximately 133 000 involved valvular repair or replacement. Aortic valve replacement was by far the most common valvular operation, followed by mitral valve repair or replacement. This review article will discuss character...
We prospectively studied 14 patients with the carcinoid syndrome to determine if two-dimensional echocardiography could detect the nature and extent of valvular abnormalities. Eight of the 14 patients had definite abnormalities of the right-sided cardiac valves. The tricuspid valve had a characteristic appearance, similar to previously described pathologic findings. The leaflets appeared diffus...
