[Hemolytic anemia secondary to paravalvular regurgitation].
Rev Esp Cardiol 2002;55(9):987 987 A 73-year-old woman was admitted for severe anemia 2 months after mitral and aortic cardiac valve replacement with Saint Jude mechanical prostheses. The differential blood count showed macrocytic anemia (hemoglobin 7.1 g/dL; MCV 111 fl; corrected reticulocyte count, 3.5%). The blood smear revealed marked anisopoikilocytosis, intense polychromasia, and abundant...
متن کاملParavalvular Regurgitation: Clinical Outcomes in Surgical and Percutaneous Treatments
BACKGROUND Paravalvular regurgitation (paravalvular leak) is a serious and rare complication associated with valve replacement surgery. Studies have shown a 3% to 6% incidence of paravalvular regurgitation with hemodynamic repercussion. Few studies have compared surgical and percutaneous approaches for repair. OBJECTIVES To compare the surgical and percutaneous approaches for paravalvular reg...
متن کاملQuantitative assessment of paravalvular regurgitation following transcatheter aortic valve replacement
Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement is a known complication associated with poorer outcomes. This article discusses the current techniques for assessing the severity of PVR, including angiography, hemodynamics, MRI, and echocardiography. The strengths and pitfalls of each modality are reviewed.
متن کاملPrevalence and severity of paravalvular regurgitation in the Artificial Valve Endocarditis Reduction Trial (AVERT) echocardiography study.
OBJECTIVES The purpose of this study was to determine the prevalence and severity of paravalvular regurgitation (PVR) in the Artificial Valve Endocarditis Reduction Trial (AVERT) cohort. BACKGROUND The initial AVERT cohort consisted of 807 patients randomized to receive either a Silzone-coated prosthetic valve or a conventional prosthetic valve; early clinical reports showed higher rates of v...
متن کاملAnatomic and procedural predictors of paravalvular aortic regurgitation after implantation of the Medtronic CoreValve bioprosthesis.
OBJECTIVES The purpose of this study was to determine the predictors of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI has been associated with a high rate of paravalvular regurgitation, usually mild. Nevertheless, moderate to severe regurgitations still occur and may have negative clinical consequences. METHODS Fifty patients with severe aor...
