Acute massive mitral regurgitation from prosthetic valve dysfunction.
Two cases of prosthetic valve dysfunction resulting in acute massive mitral regurgitation are reported; emergency operation was successful in both cases. Survival following complete dislodgement of the occluder of a disc valve, as occurred in one case, does not appear to have been reported before. The diffculty in diagnosis of sudden cardiac decompensation in patients with prosthetic valves is ...
متن کاملMassive Hemoptysis due to Acute Mitral Regurgitation with Sporadic Primary Mitral Valve Prolapse
The most common cardiac cause of massive hemoptysis is mitral stenosis. Mitral regurgitation is rarely complicated by massive hemoptysis. A 48-year-old man with no significant medical history was admitted to our hospital with hemoptysis and production of 500 mL of blood within 24 hours. A pan-systolic murmur was found on chest examination. A chest computed tomography showed airspace consolidati...
متن کاملAcute thrombosis of a prosthetic mitral valve.
We report the case of a patient who was transferred to our hospital with acute thrombosis of a prosthetic mitral valve. Her admission INR was subtherapeutic. The transoesophageal echocardiographic images are presented. The patient underwent urgent reoperation and made a good recovery.
متن کاملAssessing prosthetic mitral valve regurgitation by transoesophageal echo/Doppler.
Transoesophageal echocardiography has greatly improved our ability to detect structural and regurgitant abnormalities associated with prosthetic mitral valves.
متن کاملIntermittent acute aortic valve regurgitation: a case report of a prosthetic valve dysfunction.
Complications of any mechanical prosthesis include thrombus or pannus formation. In our case report we demonstrate that prosthetic aortic valve regurgitation due to pannus formation may be intermittent and non-cyclic in pattern and therefore not obvious at the time of original clinical examination. Under these conditions and as transesophageal echocardiography cannot be repeated promptly, trans...
