There was no significant difference between ventricular pressure, LV dP/dt or heart rate between groups. There was a significantly higher transvalvular pressure loss within both groups with the force transducers in situ corresponding to a mild stenosis. However, there was no significant difference in transvalvular pressure with the force transducers implanted between the 2 groups. The double-ring procedure itself caused a significant increase in transvalvular pressure loss compared with a single ring (double ring: 33 ± 17 mmHg; single ring: 21 ± 7 mmHg, P = 0.04). All pigs had no or trivial aortic insufficiency at any time during the procedure.\nTable 1: Haemodynamic parameters in the 2 groups with and without force transducers\nParameter With force transducers Without force transducers\nSingle ring Double ring P-value Single ring Double ring P-value\nHR (min−1) 87 ± 15 101 ± 15 NS 108 ± 18 102 ± 19 NS\nLVP max (mmHg) 106 ± 14 110 ± 14 NS 87 ± 11 99 ± 15 NS\nTvP max (mmHg) 38 ± 14 43 ± 17 0.04 21 ± 7 33 ± 17 0.04\nLV dP/dt max (mmHg/s) 1833 ± 432 1778 ± 416 NS 1589 ± 429 1675 ± 442 NS\nTotal ECC time (min) 276 ± 36\nCross-clamp time (min) 149 ± 12\nAll data are presented as mean ± standard deviation.\nECC: extracorporeal circulation; HR: heart rate; LVP: left ventricular pressure; Max: maximum; LV dP/dt: time derivative of left ventricular pressure; TvP: transvalvular pressure; NS: non-significant.","divisions":[{"label":"title","span":{"begin":0,"end":20}},{"label":"p","span":{"begin":21,"end":723}},{"label":"label","span":{"begin":724,"end":732}},{"label":"caption","span":{"begin":734,"end":808}},{"label":"p","span":{"begin":734,"end":808}},{"label":"table","span":{"begin":809,"end":1263}},{"label":"tr","span":{"begin":809,"end":869}},{"label":"th","span":{"begin":809,"end":818}},{"label":"th","span":{"begin":820,"end":842}},{"label":"th","span":{"begin":844,"end":869}},{"label":"tr","span":{"begin":870,"end":940}},{"label":"th","span":{"begin":870,"end":881}},{"label":"th","span":{"begin":883,"end":894}},{"label":"th","span":{"begin":896,"end":904}},{"label":"th","span":{"begin":906,"end":917}},{"label":"th","span":{"begin":919,"end":930}},{"label":"th","span":{"begin":932,"end":940}},{"label":"tr","span":{"begin":941,"end":998}},{"label":"td","span":{"begin":941,"end":951}},{"label":"td","span":{"begin":953,"end":960}},{"label":"td","span":{"begin":962,"end":970}},{"label":"td","span":{"begin":972,"end":974}},{"label":"td","span":{"begin":976,"end":984}},{"label":"td","span":{"begin":986,"end":994}},{"label":"td","span":{"begin":996,"end":998}},{"label":"tr","span":{"begin":999,"end":1059}},{"label":"td","span":{"begin":999,"end":1013}},{"label":"td","span":{"begin":1015,"end":1023}},{"label":"td","span":{"begin":1025,"end":1033}},{"label":"td","span":{"begin":1035,"end":1037}},{"label":"td","span":{"begin":1039,"end":1046}},{"label":"td","span":{"begin":1048,"end":1055}},{"label":"td","span":{"begin":1057,"end":1059}},{"label":"tr","span":{"begin":1060,"end":1121}},{"label":"td","span":{"begin":1060,"end":1074}},{"label":"td","span":{"begin":1076,"end":1083}},{"label":"td","span":{"begin":1085,"end":1092}},{"label":"td","span":{"begin":1094,"end":1098}},{"label":"td","span":{"begin":1100,"end":1106}},{"label":"td","span":{"begin":1108,"end":1115}},{"label":"td","span":{"begin":1117,"end":1121}},{"label":"tr","span":{"begin":1122,"end":1199}},{"label":"td","span":{"begin":1122,"end":1143}},{"label":"td","span":{"begin":1145,"end":1155}},{"label":"td","span":{"begin":1157,"end":1167}},{"label":"td","span":{"begin":1169,"end":1171}},{"label":"td","span":{"begin":1173,"end":1183}},{"label":"td","span":{"begin":1185,"end":1195}},{"label":"td","span":{"begin":1197,"end":1199}},{"label":"tr","span":{"begin":1200,"end":1230}},{"label":"td","span":{"begin":1200,"end":1220}},{"label":"td","span":{"begin":1222,"end":1230}},{"label":"tr","span":{"begin":1231,"end":1263}},{"label":"td","span":{"begin":1231,"end":1253}},{"label":"td","span":{"begin":1255,"end":1263}},{"label":"footnote","span":{"begin":1264,"end":1316}},{"label":"p","span":{"begin":1264,"end":1316}}],"tracks":[{"project":"testtesttest","denotations":[{"id":"T140","span":{"begin":149,"end":154},"obj":"Body_part"},{"id":"T144","span":{"begin":1354,"end":1359},"obj":"Body_part"}],"attributes":[{"id":"A140","pred":"uberon_id","subj":"T140","obj":"http://purl.obolibrary.org/obo/UBERON_0000948"},{"id":"A141","pred":"uberon_id","subj":"T140","obj":"http://purl.obolibrary.org/obo/UBERON_0007100"},{"id":"A142","pred":"uberon_id","subj":"T140","obj":"http://purl.obolibrary.org/obo/UBERON_0015228"},{"id":"A143","pred":"uberon_id","subj":"T140","obj":"http://purl.obolibrary.org/obo/UBERON_0015230"},{"id":"A144","pred":"uberon_id","subj":"T144","obj":"http://purl.obolibrary.org/obo/UBERON_0000948"},{"id":"A145","pred":"uberon_id","subj":"T144","obj":"http://purl.obolibrary.org/obo/UBERON_0007100"},{"id":"A146","pred":"uberon_id","subj":"T144","obj":"http://purl.obolibrary.org/obo/UBERON_0015228"},{"id":"A147","pred":"uberon_id","subj":"T144","obj":"http://purl.obolibrary.org/obo/UBERON_0015230"},{"subj":"T140","pred":"source","obj":"testtesttest"},{"subj":"T144","pred":"source","obj":"testtesttest"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"testtesttest","color":"#93ecdd","default":true}]}]}}
