Valvular Hemolysis Masquerading as Prosthetic Valve Stenosis
نویسندگان
چکیده
The evaluation of prosthetic valves can provide a unique challenge, and a thoughtful approach is required. High output states like anemia should be kept in the differential when evaluating elevated gradients across prosthetic valves. We present the case of a 69-year-old man with a Starr-Edwards prosthetic aortic valve who presented with symptoms of congestive heart failure and high transvalvular pressure gradients. These symptoms indicate a potential prosthetic valve stenosis. His laboratory evaluation results were consistent with valve-related hemolysis. Resolving his anemia led to a resolution of the symptoms and lowered the pressure gradient on follow-up.

Ö o ( c p e fi ( ( t d v ( l With the advent of the Starr-Edwards mechanical mitral and aortic valves in the 1960s, the surgical era of the treatment of cardiac valvular disease began in earnest. Although considered definitive, valve replacement surgery effectively represents an exchange of the pathophysiology of severe valvular dysfunction for the diseases and complications associated with pro...

Although renal failure is one of the known comorbidities associated with rapid progression of aortic stenosis, it is unclear whether hemodialysis alters the progression of prosthetic aortic valve stenosis. We describe a 79-year-old female who underwent bioprosthetic aortic valve replacement 8 years ago with stable prosthetic valve area for the initial 6 years. In the last two years, coinciding ...

Valvular stenosis is an uncommon finding in bacterial endocarditis involving native cardiac valves. Prosthetic valve endocarditis, however, is more commonly associated with obstruction. Bioprosthetic cardiac valves may be particularly prone to this complication. A case of bioprosthetic tricuspid valve endocarditis with stenosis diagnosed by Doppler echocardiography and confirmed by operative fi...

The purpose of this European Heart Rhythm Association (EHRA) Survey was to assess the perceptions of 'valvular' atrial fibrillation (AF) and management of AF patients with various heart valve abnormalities in daily clinical practice in European electrophysiology (EP) centres. Questionnaire survey was sent via the Internet to the EHRA-EP Research Network Centres. Of the 52 responding centres, 42...

Six cases of classical dissecting aneurysm of the aorta complicating aortic valvular disease in which aortic stenosis was dominant are described. In three of the cases the aortic complication occurred after the natural aortic valve had been replaced by a prosthetic valve. The longest postoperative period was four months. The factor common to all reported cases in our series was cystic medial ne...
