In order to limit ventricular fibrillation, an antiarrhythmic protocol was implemented, with beta-blockers\/amiodarone before and xylocaine infusion during the procedure. Clinical, angiographic, and echographic data were gathered. End points included demonstration of vessel occlusion (TIMI flow grades 0 and 1 on the angiogram), impairment of left ventricular function at 2 weeks after procedure (by echocardiography), and pathologically confirmed myocardial infarction.<jats:italic>Results.<\/jats:italic>The best arterial access was determined to be through the right carotid artery. The internal mammary guiding catheter 4-Fr was selected as the optimal device for selective intracoronary injection. Free coils deployed prematurely and tended to prolapse into the aorta. Interlocking coils did not deploy completely and failed to provide reliable results. Gelatin sponge was difficult to handle, adhered to the catheter, and could not be clearly visualized by fluoroscopy. Balloon occlusion yielded inconsistent results. Alcohol injection was the most efficient and reproducible method for inducing myocardial infarction (4 out of 6 animals), the extent of which could be fine-tuned by using a coaxial balloon catheter as a microcatheter (0.52\u2009mm) to achieve a superselective injection of 0.2\u2009mL of alcohol. This approach resulted in a 20% decrease in LVEF and infarcted myocardium was confirmed histologically.<jats:italic>Conclusions.<\/jats:italic>By following a stepwise approach, a minimally invasive, effective, and reproducible rabbit model of catheter-induced myocardial infarction has been developed which addresses the limitations of rodent experiments while avoiding the logistical and cost issues associated with large animal models.<\/jats:p>","DOI":"10.1155\/2015\/893051","type":"journal-article","created":{"date-parts":[[2015,10,4]],"date-time":"2015-10-04T21:07:28Z","timestamp":1443992848000},"page":"1-9","source":"Crossref","is-referenced-by-count":12,"title":["Comparative Analysis of Methods to Induce Myocardial Infarction in a Closed-Chest Rabbit Model"],"prefix":"10.1155","volume":"2015","author":[{"given":"Marc-Antoine","family":"Isorni","sequence":"first","affiliation":[{"name":"Department of Cardiology, H\u00f4pital Europ\u00e9en Georges Pompidou, Assistance Publique des H\u00f4pitaux de Paris, France"},{"name":"Universit\u00e9 Paris Descartes, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amaury","family":"Casanova","sequence":"additional","affiliation":[{"name":"INSERM U970, Paris Cardiovascular Research Center PARCC, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie","family":"Piquet","sequence":"additional","affiliation":[{"name":"INSERM U970, Paris Cardiovascular Research Center PARCC, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Val\u00e9rie","family":"Bellamy","sequence":"additional","affiliation":[{"name":"INSERM U970, Paris Cardiovascular Research Center PARCC, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charly","family":"Pignon","sequence":"additional","affiliation":[{"name":"National Veterinary School of Alfort, Maisons-Alfort, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Etienne","family":"Puymirat","sequence":"additional","affiliation":[{"name":"Department of Cardiology, H\u00f4pital Europ\u00e9en Georges Pompidou, Assistance Publique des H\u00f4pitaux de Paris, France"},{"name":"Universit\u00e9 Paris Descartes, Paris, France"},{"name":"INSERM U970, Paris Cardiovascular Research Center PARCC, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Menasche","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris Descartes, Paris, France"},{"name":"INSERM U970, Paris Cardiovascular Research Center PARCC, Paris, France"},{"name":"Department of Cardiovascular Surgery, H\u00f4pital Europ\u00e9en Georges Pompidou, Assistance Publique des H\u00f4pitaux de Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1161\/circresaha.113.300268"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0b013e318282ab8f"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1172\/jci200524569"},{"issue":"2","key":"4","first-page":"222","volume":"22","year":"2011","journal-title":"Cell Death & Disease"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/s003950200046"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardiores.2006.11.026"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jss.2009.06.021"},{"key":"8","series-title":"edited by: D.
