OBJECTIVE: Spinal cord infarction is a rare cause of neurologic deterioration after cervical spine decompressive surgery. Proposed causes of ischemic events include intraoperative or postoperative hypotension, or decreased venous return in conjunction with elevated vertebral venous pressures, which reduces arterial perfusion when patients undergo surgery in the prone position. Neuro-imaging ...

Ischemic mitral regurgitation results from annular dilatation, leaflet tethering and leaflet flattening. Undersized annuloplasty corrects annular dilatation but worsens leaflet tethering and flattening. This exacerbation of abnormal leaflet geometry may contribute to poor repair results for ischemic mitral regurgitation (IMR). Using a sheep model of IMR, we hypothesized that posterior ...

Cardiac cell therapy for older patients who experience a myocardial infarction may require highly regenerative cells from young, healthy (allogeneic) donors. Bone marrow mesenchymal stem cells (MSCs) are currently under clinical investigation because they can induce cardiac repair and may also be immunoprivileged (suitable for allogeneic applications). However, it is ...
