Do cardiac stabilizers really stabilize? Experimental quantitative analysis of mechanical stabilization / M. Lemma, A. Mangini, A. Redaelli, F. Acocella. - In: INTERACTIVE CARDIOVASCULAR AND THORACIC SURGERY. - ISSN 1569-9293. - 4:3(2005 Jun), pp. 222-226. [10.1510/icvts.2004.098517]
Abstract:
In order to assess the three-dimensional movement of the coronary arteries both during normal cardiac activity and after mechanical stabilization, a polypropylene black marker was placed in 10 pigs on the middle portion of the three main coronary branches. Marker motion was recorded for 10 s using two TV-digital cameras and was estimated with a precision of 50 μm. After stabilization with three different mechanical stabilizers (Medtronic, Genzyme, CTS-Guidant), a remnant coronary artery excursion of about 1.5-2.4 mm was found. There is a significant residual coronary artery motion after mechanical stabilization, which could affect the quality of anastomosis, especially in unfavourable situations.
