Long-Term Imaging and Clinical Outcomes of Surgical Left Atrial Appendage Occlusion With AtriClip.

Surgical left atrial appendage (LAA) occlusion with an AtriClip (AtriCure, West Chester, Ohio) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). We conducted a retrospective analysis of all patients with long-standing persistent AF who underwent hybrid convergent ablation and LAA clipping. Contrast-enhanced cardiac computed tomography was performed at 3 to 6 months after LAA clipping to assess the degree of complete closure and the residual LAA stump.

Sinus node sparing novel hybrid approach for treatment of inappropriate sinus tachycardia/postural sinus tachycardia: multicenter experience.

Background: The ideal treatment of inappropriate sinus tachycardia (IST) and postural orthostatic tachycardia syndrome (POTS) still needs to be defined. Medical treatments yield suboptimal results. Endocardial catheter ablation of the sinus node (SN) may risk phrenic nerve damage and open-heart surgery may be accompanied by unjustified invasive risks.

A multi-institutional outcome analysis of patients undergoing left ventricular assist device implantation stratified by sex and race.

Background: Earlier studies have demonstrated disparities in patients undergoing left ventricular assist device (LVAD) implantation when stratified according to sex and race. Because very few data exist from large investigations, we reviewed data from the registry of the Mechanical Circulatory Support Research Network.

Methods: Between May 2004 and September 2014, 734 patients underwent primary LVAD implantation at our institutions.

New sterilization technology and the effects on bone pencil.

Background: The changing technology today with sterilizing surgical tools has called into question the ability to adequately sterilize the bone pencil. Concern has arisen as to the sterilization of bone pencil and whether the new technology used in sterilizing the operating equipment meets the standards set by the Centers for Disease Control and Prevention. This study was performed to compare the older gas sterilizing technology (ETO) with the newer hydrogen peroxide-based Sterrad sterilizer.

A new dimension: robotic reconstruction in plastic surgery.

Background: Robot-assisted surgery was first approved by the Federal Drug Administration in 1994. The robotic system has the advantages of three-dimensional visualization of the operating field, 7° range of motion, tremor elimination, 360°of freedom at 10-mm distance, and a comfortable, seated operating posture. The purpose of this paper is to present a new surgical tool, the robot, for use in reconstructive surgery.
