Source: Zaw, A. M. et al. Minimally Invasive Transverse Aortic Constriction in Mice. J. Vis. Exp. (2017)
In this video, we demonstrate an experimental protocol for minimally invasive transverse aortic constriction in mice to examine pressure overload-induced heart failure.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Operation Site Preparation Disinfect the operation site with 75% isopropyl alcohol. Adjust the heating pad temperature to 37 °C to avoid changes in heart and respiratory rates of the subject animal. Use surgical instruments sterilized in a gravity displacement sterilizer at 121 °C fo…
Representative Results
Figure 1: Process of forming the desired needle hooks by bending a 1-in, 30-gauge needle tip. (A) The original 1-in, 30-gauge needle tip. (B) Grasp the needle tip with the needle holder and bend approximately halfway along its length. Bend the needle into a loop, using the needle holder and the hands, as necessary, to form the loop pictured in th…
