Starfish^™ Heart Positioner Maintains Right Ventricular Function During Lateral Wall Displacement

Abstract

<jats:sec><jats:title>Background</jats:title><jats:p> The authors examined parameters of cardiovascular function using Starfish and deep pericardial sutures (DPS) in a beating heart porcine model and to clarify toleration of right ventricular function with Starfish in lateral wall displacement. </jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p> Eight healthy pigs were used. In addition to normal pressure monitor catheters, a Swan-Ganz continuous cardiac output (CO) and end diastolic volume thermodilution catheter was used for precise and quantitative monitoring of the right ventricular function. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Lateral displacement of the heart with DPS resulted in a significant hemodynamic compromise. Cardiac output and right ventricular ejection fraction (RVEF) decreased from 3.0 ± 0.9 to 2.6 ± 1.0 L/min (P = 0.014) and from 27.9 ± 3.0% to 23.3 ± 4.8% (P = 0.019). With Starfish<jats:sup>™</jats:sup>, CO and RVEF were maintained from 3.0 ± 0.9 to 3.0 ± 0.9 L/min (P = 0.743) and from 27.9 ± 3.0% to 28.3 ± 3.8% (P = 0.476). </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Starfish<jats:sup>™</jats:sup> contributed to the stability of hemodynamics by maintaining the right ventricular function. Lateral displacement with PDS resulted in significant hemodynamic compromised compared with Starfish<jats:sup>™</jats:sup> and baseline neutral position. </jats:p></jats:sec>

Development and In Vitro Assessment of a Novel Vacuum-Based Tissue-Holding Device for Laparoscopic and Robotic Kidney Cancer Operations

“…Similar suction-based devices have or are being developed for use in other surgical contexts. The Starfish®, OCTOPUS®, and Xpose Access Device® are currently utilized in cardiovascular surgery and allow for safe and effective off-pump coronary artery bypass grafting [ 9 , 10 , 11 , 12 , 13 ] and facilitate the surgical management of mediastinal tumors [ 9 ]. The OVALEAD® is a device used in gynecologic surgery to fix the adnexa [ 14 ].…”
