Phasic (subcycle) indexes remain intrinsic to valvular stenosis and are emerging for coronary stenosis. Errors, corrections, and clinical implications of fluid\u2010filled catheter phasic pressure assessments have not been assessed in the current era of ubiquitous, high\u2010fidelity pressure wire sensors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We recruited patients undergoing invasive coronary physiology assessment. Phasic aortic pressure signals were recorded simultaneously using a fluid\u2010filled guide catheter and 0.014\u2033 pressure wire before and after standard calibration as well as after pullback. We included additional subjects undergoing hemodynamic assessment before and after transcatheter aortic valve implantation. Using the pressure wire as reference standard, we developed an automatic algorithm to match phasic pressures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Removing pressure offset and temporal shift produced the largest improvements in root mean square (RMS) error between catheter and pressure wire signals. However, further optimization &lt;1\u2009mmHg RMS error was possible by accounting for differential gain and the oscillatory behavior of the fluid\u2010filled guide. The impact of correction was larger for subcycle (like systole or diastole) versus whole\u2010cycle metrics, indicating a key role for valvular stenosis and emerging coronary pressure ratios.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>When calibrating phasic aortic pressure signals using a pressure wire, correction requires these parameters: offset, timing, gain, and oscillations (frequency and damping factor). Automatically eliminating common errors may improve some clinical decisions regarding physiology\u2010based intervention.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.28780","type":"journal-article","created":{"date-parts":[[2020,2,20]],"date-time":"2020-02-20T12:02:10Z","timestamp":1582200130000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Phasic pressure measurements for coronary and valvular interventions using fluid\u2010filled catheters: Errors, automated correction, and clinical implications"],"prefix":"10.1002","volume":"96","author":[{"given":"Daniel T.","family":"Johnson","sequence":"first","affiliation":[{"name":"Weatherhead PET Center, Division of Cardiology, Department of Medicine McGovern Medical School at UTHealth and Memorial Hermann Hospital  Houston Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephane","family":"Fournier","sequence":"additional","affiliation":[{"name":"Department of Cardiology Cardiovascular Center Aalst OLV Hospital  Aalst Belgium"},{"name":"Department of Cardiology  Lausanne University Center Hospital Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard L.","family":"Kirkeeide","sequence":"additional","affiliation":[{"name":"Weatherhead PET Center, Division of Cardiology, Department of Medicine McGovern Medical School at UTHealth and Memorial Hermann Hospital  Houston Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernard","family":"De Bruyne","sequence":"additional","affiliation":[{"name":"Department of Cardiology Cardiovascular Center Aalst OLV Hospital  Aalst Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
