Cyroinjury compared to resection. (A) After amputation of the ventricular apex (upper panel), the damaged myocardium is restricted to the narrow layer of cells above the amputation plane. A blood clot fills up the missing tissue below the plane of amputation. After cryoinjury (lower panel), a large portion of the damaged apoptotic myocardium (red) remains integrated with the functioning organ. (B) A photograph of the cryoinjury procedure. A small incision of the zebrafish chest is opened with help of forceps. The cryoprobe is placed in contact with the ventricle.
