This approach uses the sound energy released from atherosclerotic arterial tissue during in vitro balloon angioplasty to characterize type and severity of induced trauma.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            Thirty-two postmortem human peripheral arterial specimens 1.0 cm long were subjected to in vitro balloon angioplasty with simultaneous acoustic emission monitoring. Specimens were examined before and after angioplasty to ascertain the extent of angioplasty-induced injury. Gross observation was used to identify dissection. A three-dimensional intravascular ultrasound reconstruction technique was used to estimate the luminal surface area of the specimen. Change in luminal surface area (postangioplasty minus preangioplasty) was used to quantify induced injury. The energy content and spectral distribution of the digitally acquired vascular acoustic emission (VAE) signals were computed. Comparisons of angioplasty-induced trauma with VAE signal characteristics were made. Dissection (mural laceration of variable depth) was observed in 15 of 32 specimens. Eleven showed no evidence of induced dissection, and 6 had preexisting intimal disruptions. The energy content of the VAE signals collected from specimens with dissection was greater than that obtained from those in which dissection was absent: 845\u00b189.4 mJ (mean\u00b1SEM; n=15) versus 128\u00b140.8 mJ (n=11;\n            <jats:italic>P<\/jats:italic>\n            &lt;.001). Comparison of induced trauma and VAE signal energy demonstrated a proportional relationship (\n            <jats:italic>r<\/jats:italic>\n            =.87,\n            <jats:italic>P<\/jats:italic>\n            &lt;.001, n=32).\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            VAE signals contain information characterizing type and severity of angioplasty-induced arterial injury. Because vascular injury is related to adverse procedural outcome, development of VAE technology as an adjunct to conventional diagnostic modalities may facilitate optimal balloon angioplasty delivery and postprocedural care.\n          <\/jats:p>","DOI":"10.1161\/01.cir.95.4.1022","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:41:02Z","timestamp":1339461662000},"page":"1022-1029","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["In Vitro Identification of Angioplasty-Induced Injury by Use of Vascular Acoustic Emissions"],"prefix":"10.1161","volume":"95","author":[{"given":"Michael J.","family":"Vonesh","sequence":"first","affiliation":[{"name":"the Department of Medicine, Section of Cardiology (M.J.V., C.J.D., D.D.M.), and the Department of Biomedical Engineering (M.J.V., L.F.M.), Feinberg Cardiovascular Research Institute, Northwestern University, Chicago, Ill, and the College of Engineering, Department of Biomedical Engineering (K.B.C.), University of Iowa, Iowa City."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lyle F.","family":"Mockros","sequence":"additional","affiliation":[{"name":"the Department of Medicine, Section of Cardiology (M.J.V., C.J.D., D.D.M.), and the Department of Biomedical Engineering (M.J.V., L.F.M.), Feinberg Cardiovascular Research Institute, Northwestern University, Chicago, Ill, and the College of Engineering, Department of Biomedical Engineering (K.B.C.), University of Iowa, Iowa City."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles J.","family":"Davidson","sequence":"additional","affiliation":[{"name":"the Department of Medicine, Section of Cardiology (M.J.V., C.J.D., D.D.M.), and the Department of Biomedical Engineering (M.J.V., L.F.M.), Feinberg Cardiovascular Research Institute, Northwestern University, Chicago, Ill, and the College of Engineering, Department of Biomedical Engineering (K.B.C.), University of Iowa, Iowa City."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishnan B.","family":"Chandran","sequence":"additional","affiliation":[{"name":"the Department of Medicine, Section of Cardiology (M.J.V., C.J.D., D.D.M.), and the Department of Biomedical Engineering (M.J.V., L.F.M.), Feinberg Cardiovascular Research Institute, Northwestern University, Chicago, Ill, and the College of Engineering, Department of Biomedical Engineering (K.B.C.), University of Iowa, Iowa City."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David D.","family":"McPherson","sequence":"additional","affiliation":[{"name":"the Department of Medicine, Section of Cardiology (M.J.V., C.J.D., D.D.M.), and the Department of Biomedical Engineering (M.J.V., L.F.M.), Feinberg Cardiovascular Research Institute, Northwestern University, Chicago, Ill, and the College of Engineering, Department of Biomedical Engineering (K.B.C.), University of Iowa, Iowa City."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.135.3.7384437"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198108133050706"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(89)90248-9"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.80.4.2529057"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.72.5.2931211"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.72.3.3160507"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.77.2.2962787"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.82.3.2394000"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.79.5.2523763"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0167-5273(91)90268-T"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(91)90780-O"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.66.1.3"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0950-821X(87)80049-X"},{"key":"e_1_3_2_14_2","first-page":"1211","volume":"114","year":"1990","unstructured":"Prayson RA, Ratliff NB.
