Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

An intelligent nanoreservoir system promotes heart valve regeneration via ROS scavenging and immunomodulation

Bioactive Materials
In situ regeneration of tissue-engineered heart valves (TEHV) is a promising strategy to overcome the limitations of existing heart valve prostheses. Although, decellularized aortic valves (DAVs) are widely regarded as a scaffold in the construction of ...

Segmental Snare Traction Technique for Helix‐Fixed Leadless Pacemaker Implantation Across a Repaired Tricuspid Annulus

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Helix‐fixed leadless pacemaker delivery can be challenging after tricuspid annuloplasty with a rigid ring. An 80‐year‐old woman with prior mitral valve repair, tricuspid annuloplasty (26‐mm MC ring), and Maze III surgery presented with syncope due to atrial fibrillation with a slow ventricular response. Standard maneuvers failed to advance the

In vitro detection of thrombotic formation on bileaflet mechanical heart valves.

, 2011
As with all mechanical prostheses, bileaflet heart valves are prone to thrombus formation, reduced hemodynamic performance, and the occurrence of embolic events.
