A simple method to establish antegrade cerebral perfusion during hemiarch reconstruction.

Objective: We describe a novel and safe technique using a 12F-14F pediatric arterial cannula to establish unilateral, selective, antegrade cerebral perfusion (ACP) during open hemiarch reconstruction.

Methods: Between January 2015 and September 2018, 42 patients underwent elective aortic aneurysm repair requiring an open distal anastomosis and at least a hemiarch replacement via hypothermic circulatory arrest by 2 surgeons. All distal reconstructions were performed at moderate hypothermia (22°C-26°C) with direct cannulation of the innominate artery (IA) using a pediatric arterial cannula to allow ACP at 10-15 mL/kg/min.

Long-Term Outcomes of Mosaic Versus Perimount Mitral Replacements: 17-Year Follow-Up of 940 Implants.

Background: The objective of this study was to compare long-term outcomes of Mosaic (Medtronic, Minneapolis, MN) porcine mitral valves to Carpentier-Edwards (Edwards Lifesciences, Irving, CA) bovine pericardial mitral valves.

Methods: From 2001 through 2017 at a single institution, 940 patients received a mitral bioprosthesis, of which 463 (49.3%) were porcine and 477 (50.

Use of EN Snare device for successful repositioning of the newest self-expanding transcatheter heart valve.

Once a self-expanding transcatheter aortic valve replacement is fully deployed, a snare device must be used to retrieve it. Minimal data are available regarding technique, efficacy, and complications associated with the retrieval of such valves. Here, we present two patients in which an EN Snare Device (Merit Medical System, South Jordan, UT, USA) was safely and effectively used to retrieve and reposition the latest generation self-expanding transcatheter aortic valve replacement.

Use of an Automated Suture Fastening Device in Minimally Invasive Aortic Valve Replacement.

Background: Minimally invasive aortic valve replacement (mAVR) is gaining clinical acceptance; however, it is associated with increased operative times because of the limited surgical field and access. The Cor-Knot (CK; LSI Solutions, Victor, NY) is an automated fastening device designed to facilitate suture fastening, but clinical data in mAVR are lacking.

Methods: From May 2014 to February 2017, 92 patients underwent mAVR at Spectrum Health in Grand Rapids, Michigan; 39 valves were secured with manually tied sutures, and 53 valves were entirely secured with the CK device.
