BACKGROUND As the prognosis of women with prosthetic heart valves improves, an increasing number are contemplating and undertaking pregnancy. Accurate knowledge of perinatal outcomes is essential, assisting counseling and guiding care. The aims of this study were to assess outcomes in a contemporary population of women with heart valve prostheses undertaking pregnancy and to compare outcomes fo...
BACKGROUND Mechanical prosthetic heart valves have been used for many decades to replace damaged native valves. Guidelines mandate the use of anticoagulant therapy in patients with mechanical prosthetic valves of any type, irrespective of the position in the heart. The rationale for this is to prevent valve thrombosis and thromboembolic complications without increasing the risk of excess bleedi...
We report two patients with a history of prior mitral valve and aortic valve replacement with St. Jude prosthetic valves, who were referred for repeat valve replacement after noninvasive assessment was suggestive of prosthetic valve malfunction. Both patients were managed medically after evaluation with direct left ventricular apical puncture revealed normal hemodynamics in the first and mild a...
For prosthetic heart valves the risk of infection is much higher than for native heart valves. During the course of infective endocarditis 20-40% of all patients suffer from cerebrovascular complications such as ischaemic stroke or intracerebral haemorrhage. We present the case of a 57-year-old woman who had undergone surgery to mechanically replace an aortic heart valve 11 months ago and suffe...
Patients with metallic prosthetic heart valves have to use anticoagulants throughout their life because of avoiding prosthetic valve thrombosis. We report the case of a patient with a prosthetic aortic valve without any event to date despite not using warfarin for 31 years. A 53-year-old man who underwent aortic valve replacement (AVR) with a mechanical valve (Medtronic,Inc., Minneapolis, Mines...
Prosthetic valve endocarditis is a clinically severe pathology, which, unless timely treated, rapidly leads to the development of heart failure. The severity disease caused by fact that microorganisms and toxins bypass biological barriers constantly enter bloodstream, which subsequently results in sepsis with systemic embolism multiple organ conservative antibiotic therapy often ineffective due...
Mitral valve regurgitation (MR) is uncommon as an isolated lesion in congenital heart disease. In 1995, we encountered two children with congenital isolated MR complicated with heart failure, and both underwent valvuloplastic surgery. Resection and/or plication of the redundant leaflets combined with annuloplasty for the dilated annulus successfully restored the valve competency. Traditionally ...
BACKGROUND A Dutch online patient decision aid to support prosthetic heart valve selection was recently developed. A multicenter randomized controlled trial was conducted to assess whether use of the patient decision aid results in optimization of shared decision making in prosthetic heart valve selection. METHODS AND RESULTS In a 5-center randomized controlled trial, patients were allocated ...
Introduction: Observing microembolic signals in brain vessels by transcranial Doppler technology is a very common finding in patients with mechanical heart valve. These signals are almost always clinically asymptomatic. The aim of this study was assessment of transcranial Doppler in detecting probability of stroke in patients with mechanical heart valve. Methods: This descriptive study was ca...
