Evaluation of ascending aortic atherosclerosis with 16-multidetector computed tomography is useful before total endoscopic coronary bypass surgery
The purpose of this study was to investigate the assessment of ascending aortic atherosclerosis with 16-multidetector computed tomography (16-MDCT) angiography prior to total endoscopic coronary artery bypass (TECAB) surgery. Forty-five patients were examined with electrocardiogram-gated, 16-MDCT an...

Forty-five patients were examined with electrocardiogram-gated, 16-MDCT angiography. The presence of atherosclerosis at the ascending aorta was graduated as severe (>50% of circumference) or as mild (<50% of circumference). Ascending aortic plaque composition was evaluated based on CT densities expressed as Hounsfield units (HU). TECABs using the Da Vinci telemanipulator were performed either on the arrested heart (n = 39) with an intra-aortic cardiopulmonary bypass (CPB) perfusion device or on the beating heart (n = 6) in patients with severe atherosclerosis.
The presence of mild atherosclerosis at the ascending aorta (11/39) was associated with intra-aortic CPB perfusion device-related difficulties such as intra-aortic balloon migration (BM) or balloon rupture (P = .007) in arrested heart TECABs. The CT density of atherosclerotic plaque in patients with BM was mean 58 HU +/- 51 standard deviation (SD), suggesting noncalcifying plaque. In patients without BM, CT density of plaque was mean 526 HU +/- 306 SD corresponding to calcifying plaque (P < .001). Balloon rupture occurred in 2 patients who had calcifying plaque at the ascending aorta.
Evaluation of ascending aortic atherosclerosis with 16-MDCT angiography is useful prior to TECAB surgery. Even mild atherosclerosis of the ascending aorta is associated with intraoperative difficulties regarding the remote-access perfusion system that is used for arrested heart TECAB surgery.</description><identifier>ISSN: 1098-3511</identifier><identifier>EISSN: 1522-6662</identifier><identifier>DOI: 10.1532/HSF98.20051103</identifier><identifier>PMID: 16809129</identifier><language>eng</language><publisher>United States</publisher><subject>Aorta ; Aortic Diseases - diagnostic imaging ; Atherosclerosis - diagnostic imaging ; Coronary Artery Bypass - methods ; Endoscopy ; Female ; Humans ; Male ; Middle Aged ; Preoperative Care ; Robotics ; Tomography, X-Ray Computed</subject><ispartof>The Heart surgery forum, 2006, Vol.9 (5), p.E754-E758</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c363t-623e259697992dc1b71d3c92ba19662e4dd2f337678c92f696fd757ad7de73673</citedby><cites>FETCH-LOGICAL-c363t-623e259697992dc1b71d3c92ba19662e4dd2f337678c92f696fd757ad7de73673</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,4024,27923,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/16809129$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Feuchtner, Gudrun Maria</creatorcontrib><creatorcontrib>Schachner, Thomas</creatorcontrib><creatorcontrib>Bonaros, Nikolaos</creatorcontrib><creatorcontrib>Smekal, Alexander</creatorcontrib><creatorcontrib>Mallouhi, Ammar</creatorcontrib><creatorcontrib>Friedrich, Guy J</creatorcontrib><creatorcontrib>Deutschmann, Martin</creatorcontrib><creatorcontrib>Laufer, Guenther</creatorcontrib><creatorcontrib>zur Nedden, Dieter</creatorcontrib><creatorcontrib>Bonatti, Johannes</creatorcontrib><title>Evaluation of ascending aortic atherosclerosis with 16-multidetector computed tomography is useful before total endoscopic coronary bypass surgery</title><title>The Heart surgery forum</title><addtitle>Heart Surg Forum</addtitle><description>The purpose of this study was to investigate the assessment of ascending aortic atherosclerosis with 16-multidetector computed tomography (16-MDCT) angiography prior to total endoscopic coronary artery bypass (TECAB) surgery.
