Aortic valve abscesses (AVAs) are a devastating complication of aortic valve endocarditis. Over 8 years, 25 patients were diagnosed with AVA by transesophageal echo (TEE). Management and outcomes were then analyzed. Eleven (44%) AVAs involved prosthetic valves, and 6 (24%) occurred in congenitally malformed valves. Twenty patients (80%) underwent surgical ...

Four patients with no known predisposing conditions developed tricuspid valve endocarditis. All patients had community-acquired infection with a rapidly progressive course that was complicated by right heart failure and respiratory insufficiency. Pulmonary involvement was prominent in all cases. The infectious process was due to Staphylococcus aureus in three patients and ...

STUDY OBJECTIVES: Blood flow in the aorta is complex and incompletely characterized. Mobile aortic plaques (MAPs), moving freely with the pulsatile aortic flow, in fact represent natural tracers that reflect the flow pattern itself. Our aim was to use MAP motion on transesophageal echocardiography (TEE) in order to characterize flow ...

Although it is well recognized that a peripheral vasculopathy may occur in patients with neurofibromatosis 1 (NF1), it is unclear whether cardiovascular abnormalities are more common. We reviewed the frequency of cardiovascular abnormalities, in particular, cardiovascular malformations (CVMs), among 2322 patients with definite NF1 in the National Neurofibromatosis Foundation International ...

BACKGROUND AND PURPOSE: Although mitral annulus calcification (MAC) has been reported to be a significant independent predictor of stroke, no causative relationship was proven. It is also known that aortic atheroma (AA), especially those >/=5 mm thick and/or protruding and/or mobile are associated with stroke. This study was designed to ...

It has recently been claimed that giant cell arteritis (GCA) is associated with a markedly increased risk of aortic aneurysm formation or rupture. In the present study, the opposite approach was taken, by looking for the incidence of GCA and polymyalgia rheumatica (PMR) in patients with aortic aneurysm, aortic dissection, ...

Retrograde holodiastolic flow in the abdominal aorta (retrograde flow) detected by pulsed Doppler echocardiography is usually noted in patients with aortic regurgitation or patent ductus arteriosus. Similar abnormal flow often is present in patients with acute phase Kawasaki Disease (KD). In 21 patients with acute phase KD, 15 had a ...

Patients with mitral valve disease undergoing surgery are at an increased risk of thromboembolism. We hypothesized that this may be due in part to abnormalities in platelet activation, endothelial damage or dysfunction, and plasma fibrinogen in such patients. To test this hypothesis, we measured indexes of platelet activation (soluble P-selectin), ...

BACKGROUND: Mitral valve prolapse (MVP) is the most frequently diagnosed valvular disease, but its pathophysiology remains elusive. Its complete absence in 1,734 neonatal echocardiographic studies suggests that this may be an acquired rather than a congenital disease. We observed several patients with distorted cardiac and valvular anatomies on electron beam ...

Tricuspid valve involvement is not uncommon in patients with rheumatic heart disease and is frequently missed on routine clinical examination. We prospectively studied the echocardiographic profile of tricuspid valve disease in 788 consecutive patients with rheumatic heart disease. Out of these patients 9% (70) had tricuspid valve disease and 55.7% ...
