A 75-year-old man, 8 years after CABG, with ischemic cardiomyopathy underwent cardiac resynchronization therapy (CRT) for refractory heart failure. Retrograde occlusion venography revealed absence of lateral vein. A functionally occluded middle cardiac vein with branch to anterolateral vein was used for left ventricular lead implantation. Using a collateral route for left ventricular lead implantation is a new technique. Lead position was stable with excellent threshold. Follow-up at 6 months reveals continued stable lead position.

Since infections associated with microbial communities threaten human health, research is increasingly focusing on the development of biofilms and strategies to combat them. Bacterial communities may include bacteria of one or several species. Therefore, examining all the microbes and identifying individual community bacteria responsible for the infectious process is important.

Summary Of Background Data: Fusion surgery has been used to treat chronic low back pain caused by degenerative disk disease (DDD). The traditional pedicle screw system made of titanium, though biocompatible, can lead to complications, such as stress shielding and implant failure.
Measurement of Tip Load With a Pacemaker Lead Stylet and Guiding Catheter Using a Silicone Heart Model.

Background Ventricular septal pacing has long been performed using a stylet during pacemaker implantation, but with the availability of guiding catheters, His bundle pacing and left bundle branch area pacing have also been performed. However, it is not known to what extent the tip load of the ventricular lead differs when a guiding catheter is used compared with a stylet alone. In this study, the tip load was measured for different stylet stiffness and guiding catheter geometries at sites where His bundle pacing and left bundle branch area pacing were assumed.

Background: Complete endothelialization is often not achieved within 6 months after implantation of an atrial septal defect (ASD) occluder, which may lead to microthrombus or thrombosis. This study aimed to assess the endothelialization and morphology of a novel puncturable ASD occluder (ReAces) compared with traditional occluders 1 year post-implantation using computed tomography angiography (CTA).
Methods: Fifteen patients from each group in a randomized controlled trial comparing ReAces with traditional occluders were included at the 1-year follow-up at Zhongshan Hospital, Fudan University.

Statement Of Problem: Excess cement in implant-supported restorations can lead to peri-implant diseases, and its removal remains a clinical challenge. The optimum method of minimizing excess cement is unclear.
Purpose: The purpose of this in vitro study was to compare 3 cementation techniques and 3 cement types and measure excess cement.
