Coronary sinus lead placement for transvenous left ventricular (LV) pacing in cardiac resynchronization therapy (CRT) has a significant failure rate at implant and a significant dislocation rate during follow-up. For these patients, epicardial pacing lead implantation is the most frequently used alternative. The aim of this case report is to describe a fundamentally new approach for the endocardial LV lead implantation. An epicardial lead implantation was planned, but after thoracotomy, extensive pericardial adhesions were found. An active fixation lead was placed into the LV cavity using the standard Seldinger technique through the LV apex. After an uneventful post-operative period at the 3- and 6-month follow-up visits, the patient had effective CRT with unchanged pacing parameters. In conclusion, this is the very first report showing feasibility of transapical LV lead implantation.

Evaluation of the influence of connection configuration on the implant-abutment interface vertical misfit of original milled titanium and laser-sintered cobalt-chromium abutments.
Clin Oral Investig

Department of Conservative Dentistry and Bucofacial Prostheses, Faculty of Odontology, Complutense University of Madrid, Madrid, Spain.
Objectives: This study aimed to assess the vertical misfit at the implant-abutment interface in external and internal connections across various implant brands, comparing original milled titanium abutments with laser-sintered cobalt-chromium (Co-Cr) abutments.
Materials And Methods: A total of 160 implants from four different brands were utilized, with 80 featuring external connections (EC) and 80 internal connections (IC). Original milled titanium abutments (n = 160) and Co-Cr laser-sintered abutments (n = 160) were randomly attached to each connection type, following the manufacturer's recommended torque.
Universal Hydrogel Carrier Enhances Bone Graft Success: Preclinical and Clinical Evaluation.

Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor-site bone harvesting can be associated with post-surgical complications. There has been widespread adoption of exogenously sourced particulate bone graft materials (BGM) for bone regenerative procedures; however, the particulate nature of these materials may lead to compromised healing outcomes, mainly attributed to structural collapse of the BGM, prolonged tissue healing. In this study, a fully synthetic thermoresponsive hydrogel-based universal carrier matrix (TX) that forms flowable and shapable putties with different BGMs while spatially preserving the particles in a 3D scaffold at the implantation site is introduced.

Without timely intervention, this condition can lead to disastrous outcomes. The advent of transcatheter aortic valve implantation (TAVI) has gained popularity, emerging as an effective alternative for managing severe aortic stenosis (AS) in high-risk patients experiencing deterioration of previously implanted bioprosthetic surgical aortic valves (SAV), which introduces complex challenges such as device compatibility and anatomical considerations.

Hydroxyapatite (HAP) nano-coatings on titanium alloys (for example, Ti6Al4V) have been used for prosthetic orthopedic implants in recent decades due to their osseointegration, bioactivity, and biocompatibility. HAP is brittle with low mechanical strength and poor adhesion on metallic surfaces, which limits its durability and bioactivity. Surface modification techniques have alleviated the imperfection of biomaterials by coating the substrate.

Objective: To provide evidence to use an extended frequency pure tone average to screen for cochlear implant evaluation candidates as recommended by the American Cochlear Implant Alliance. Additionally, to determine whether traditional low frequency, high or low frequency, high frequency, or extended frequency pure tone average most accurately predicts cochlear implant candidates based on speech perception scores from aided AzBio sentence testing or aided consonant-nucleus-consonant (CNC) testing.
Method: Adults from a tertiary care center who completed aided sentence testing during cochlear implant evaluation between 2014 and 2024 were assessed.
