The left atrium (LA) was resected, and the left ventricle (LV) was pressurized retrograde to 27\u2009\u00b1\u20091mm Hg. An endoscope was inserted into the LV apex, centered under the MV orifice. An FS system (Milliscope II camera, LED light source, and 0.7\u2005mm diameter \u00d7 15\u2005cm long) 90\u00b0 semirigid scope with 1.2\u2005mm focal length) was mounted above the MV annulus in a custom alignment and measuring fixture. Three blinded measurements were taken at two locations on each MV, A2 and P2 segment, from the top of coaptation to the leaflet edge identified by the FS. Accurate positioning was verified using the LV endoscope. A control (metal rod of similar thickness) was used for comparison, with coaptation height recorded when the control was seen via the endoscope.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Coaptation heights were similar for the control and FS methods across all hearts at A2 (11.6\u2009\u00b1\u20092.6\u2005mm control vs 11.8\u2009\u00b1\u20092.2\u2005mm FS) and P2 (13.3\u2009\u00b1\u20092.6\u2005mm control vs 13.4\u2009\u00b1\u20092.9\u2005mm FS) segments, with similar measurement variability (control SD 0.1-1.0\u2005mm; FS SD 0.1-0.9\u2005mm). One outlier was excluded from analysis (n\u2009=\u200919\/20). The maximum absolute difference and percent error between measurement methods were less than 1.1\u2005mm (median [IQR], 0.6 [0.3-0.9] mm) and less than 14% (4.1 [2.2-7.6]%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Utilization of a miniaturized FS enabled precise and accurate quantification of MV coaptation.
