Lack of Accessible Data on Prosthetic Heart Valves. International Journal of Cardiovascular Imaging, 32(3):439-447.

Abstract

Incomplete information on characteristics of prosthetic heart valves (PHV) may lead to inappropriate choices for PHV implantation (patient-prosthesis-mismatch) or erroneous interpretation of PHV function after implantation. No single and easy accessible source provides all relevant information on PHV. The aim of this study was to provide a comprehensive overview of available data for the majority of PHVs and annuloplasty rings. Information was collected by reviewing articles published on www.pubmed.org up to December 2014 and by written contact to all PHV manufacturers. Four areas of interest were defined: (1) PHV image, (2) in vivo transvalvular gradients, (3) effective orifice area (EOA) calculators and (4) PHV dimensions. Available information was classified as complete (all categories), partial (two or three categories) or minimal (one category). 108 PHV (including homografts) and 34 annuloplasty rings systems were identified. The information on PHV was complete, partial or minimal in 19.5, 61.0 and 19.5 % of PHV, respectively. In 91.6 % a picture of the valve could be obtained, whereas normative data for transvalvular gradients and EOA calculators were available in 63.0 and 25.0 % of all PHV, respectively. The available data was summarized on a new open access webpage ( www.valveguide.ch ). There is a lack of accessible data on PHV dimensions, normal transvalvular gradients and effective orifice area calculators, although such information is of crucial importance for proper PHV assessment.
