Fulminant thrombosis of mechanical mitral valve prosthesis.
In patients with prosthetic heart valves non-cardiac surgery may require temporary discontinuation of oral anticoagulation. Although the risk of valve related thromboembolic complications may generally be only slightly increased during the short perioperative period, in the presence of certain risk factors, replacement of oral anticoagulation with heparin is recommended. In the presented patien...
متن کاملIntermittent blockade of a mechanical mitral valve prosthesis.
A 65-year-old man was referred with refractory heart failure. A 27-mm Carbomedics bileaflet valve for mitral valve stenosis had been implanted 20 years earlier. The electrocardiogram showed atrial fibrillation with severe bradycardia (30-50/min). Transthoracic echocardiography demonstrated both prosthetic leaflets opening in late diastole (Picture A, arrows), and the anterolateral leaflet inter...
متن کاملAcute dysfunction from thrombosis of a mechanical mitral valve prosthesis
An 64-year-old man received a 31-mm CarboMedics mechanical prosthesis for severe mitral regurgitation. After four days the patient presented fatigue and dyspnoea with rest; transthoracic and transesophageal Doppler echocardiographic study confirmed a failing mobility of prosthetic valve leaflet from thrombosis and an emergency operation was done. The postoperative course was uneventful. This is...
متن کاملMitral Ball-Valve Prosthesis
REPLACEMENT of nonfunctioning valves is a significant recent advancement in the correction of cardiac valvular disease. The most widely used artificial device replacing the mitral valve is the Starr-Edwards ballvalve prosthesis.' Its effectiveness was shown in recent reports by the marked clinical improvement in properly selected patients.2 However, cardiologists and cardiac surgeons are faced ...
متن کاملApical aortic valve implantation in a patient with a mechanical valve prosthesis in mitral position.
A 67-year-old man diagnosed with severe aortic stenosis was admitted to our institution with pulmonary edema. The patient had a history of severe pulmonary fibrosis (total lung capacity, 57% of predicted value; diffusing capacity for carbon monoxide, 33% of predicted value) and had undergone coronary bypass grafting and mitral valve replacement with a St Jude mechanical valve (St Jude Medical, ...
