Influence of anastomotic techniques in totally endoscopic coronary artery bypass.

Background: Beating heart totally endoscopic coronary artery bypass grafting (TECAB) utilizing a computer-enhanced telemanipulation system is a technically challenging procedure. The objective of our study was to compare two different anastomotic techniques.

Methods: Ten canine beating heart TECAB procedures were performed using Intuitive's daVinci surgical system.

Multicenter mitral valve study: a lateral approach using the da vinci surgical system.

Objective: : The purpose of this study was to demonstrate the feasibility of simple to complex endoscopic robotic mitral valve repair, using a lateral approach.

Methods: : Data were retrospectively collected on 201 patients undergoing a lateral "ports only" endoscopic robotic mitral valve repair at three institutions. Techniques of aortic occlusion included the endoaortic balloon or a transthoracic clamp.

Target vessel detection and coronary anastomosis assessment by intraoperative 12-MHz ultrasound.

Purpose: Our aim was to assess whether the left internal mammary artery, left anterior descending artery, and anastomosis could be visualized by intraoperative ultrasound for safe graft harvesting, optimal anastomotic target selection, and quality control.

Description: In 10 patients, the left internal mammary artery, the left anterior descending artery, and the constructed anastomosis were scanned with 12-MHz epicardial ultrasound. Anastomosis quality was assessed on ultrasound and compared with surgeon score.

Proactive spraying against boll weevils (Coleoptera: Curculionidae) reduces insecticide applications and increases cotton yield and economic return.

The current standard practice of two to three preemptive insecticide applications at the start of pinhead (1-2-mm-diameter) squaring followed by threshold-triggered (whenever 10% of randomly selected squares have oviposition punctures) insecticide applications for boll weevil, Anthonomus grandis grandis Boheman, control does not provide a reliably positive impact on cotton, Gossypium hirsutum L., yields in subtropical conditions. This study showed that four fewer spray applications in a "proactive" approach, where spraying began at the start of large (5.
