ABSTRACT: Flow Characteristics of Aortic Cannulae; Journal of Cardiac Surgery 1995; s4(10) 514-519. Muehrcke, D et al.
The authors describe an aortic cannulae designed to reduce jet spray and peak blood velocity and produce a diffuse, high-flow perfusion to potentially reduce atheroemboli from the ascending aorta.
ABSTRACT: Left Hemisperic Strokes in Coronary Surgery: Implications for End-Hole Aortic Cannulas; The Annals of Thoracic Surgery 2001; 71(1): 128-132. Weinstein, G.
The author compares end-hole aortic cannulae with side-hole aortic cannulae as they relate to perioperative stroke rates and finds side-hole aortic cannulae may significantly reduce the perioperative stroke rate.
ABSTRACT: Does the Arterial Cannulation Site for Circulatory Arrest Influence Stroke Risk?, Ann Thorac Surg 2004;78:1274-1284; Svensson, L., et al.
In a comparative study, the authors concluded that axillary inflow with a graft reduces stroke for complex cardiac and cardioaortic operations that necessitate circulatory arrest.
