Abstract

Objectives-In many heart centers myocardial revascularization using beating heart coronary surgery has partly replaced conventional coronary artery bypass grafting (cCABG) using cardiopulmonary bypass. However, access to themarginal arteries is problematic and hampered by space limitations, which might compromise the quality of the anastomoses and it entails a significant risk of hemodynamic instability subsequent to the manipulations of the heart. Hemodynamic impairment may be caused by dislocation of the low-pressure right atrium and ventricle. Therefore, it was hypothesized that the use of Right Heart Assist (RHA) may be able to ensure hemodynamic stability whentilting and manipulating the heart. Design-In an animal experimental model RHA was implemented in order to study the hemodynamic impact of dislocating the heart in a standardized fashion. Results-Dislocation of the unassisted heart to expose the first and secondmarginal branches caused a decline in arterial blood pressure, cardiac output and venous saturation of 38-48%. Supported by RHA this decrease was minimized to 0-17%. Conclusion-RHA for beating heart procedures indicates several advantages: ample time and safety while making the anastomoses at the marginal branches, less space limitations and enhanced control of hemodynamic stability compared with no RHA. This operation technique is challenging current practice and indications, and may potentially replace cCABG for the majority of patients.
