OBJECTIVE We analyzed the results of intravenous thrombolytic treatment under transesophageal echocardiographic (TEE) guidance in prosthetic valve thrombosis. BACKGROUND Thrombotic occlusion of prosthetic valves continues to be an uncommon but serious complication. Intravenous thrombolytic treatment has been proposed as an alternative to surgical intervention. METHODS In a four-year period,...

BACKGROUND AND PURPOSE Transcranial Doppler can detect cerebral microemboli. These emboli may be a risk factor for embolic stroke. We studied the prevalence of microemboli in patients referred for echocardiography. METHODS Forty-two patients were evaluated. Patients were studied with continuous monitoring over one middle cerebral artery for 30 minutes, and the number of microemboli was record...

The high accuracy of multidetector-row computed tomography (MDCT) in evaluating prosthetic valve disorders has been confirmed. This, we believe, is the 1st report of the use of MDCT to detect and evaluate left ventricular outflow tract (LVOT) pseudoaneurysms in patients who have undergone aortic valve replacement with prosthetic valves. We used MDCT to scan 21 such patients, 3 of whom had a sma...

AIM To define therapeutic ways to manage obstetrics at an optimal level for a patient carrying a mechanical prosthetic heart valve. METHOD From a review of literature and documented cases, we propose an obstetrical and cardiological management scheme for pregnant patients carrying a mechanical prosthetic heart valve. We deal successively with the preventive (anticoagulation) and curative trea...

Prosthetic valve endocarditis (PVE) represents an uncommon and very serious complication after heart valve surgery. Prosthetic valve endocarditis occurs in 1% to 6% of patients with valve prostheses and affects both mechanical and biological valves [1]. Up to 34% of all cases of infective endocarditis involve prosthetic heart valves. Prosthetic valve endocarditis represents a nosographic entity...

Abstract Background Prosthetic Heart Valves are always more frequent in the clinical practice. Particularly, sometimes than one native valve is affected and needs to be surgically treated. On other side, replaced prosthesis could also degenerate over time, leading worsening symptomatic heart failure. There no many cases of combined percutaneous approach both aortic mitral prosthetic deteriorati...

There is an increased risk of thromboembolism, anticoagulant-related hemorrhage, fetal-wastage and congestive cardiac failure in pregnant women with mechanical heart valves. In order to have a good outcome, the care of such patients must necessarily be multidisciplinary and in a well- equipped centre with adequate support services .One such patient who had mechanical mitral and aortic valves re...

Prosthesis valve dehiscence is one of the most serious complications prosthetic valves. Despite improvements in medical and surgical treatments, prosthesis has high mortality. Due to fatality rates, early diagnosis treatment these patients required. In this case report, we presented a patient with severe mitral deficiency acute heart failure following mechanical secondary culture-negative endoc...

INTRODUCTION Approximately 60 000 prosthetic valves are implanted annually in the USA. The risk of prosthesis dysfunction ranges from 0.1% to 4% per year. Prosthesis valve dysfunction is usually caused by a thrombus obstructing the prosthetic discs. However, 10% of prosthetic valves are dysfunctional due to pannus formation, and 12% of prostheses are damaged by both fibrinous and thrombotic com...
