WebcastsTopographic mapping of left ventricular regional contractile injury in ischemic mitral regurgitation.
Restrictive leaflet tethering resulting from regional left ventricular (LV) contractile injury causes ischemic mitral regurgitation (MR). We hypothesized that 3-dimensional LV topographic mapping by MRI-based multiparametric strain analysis could characterize the regional contractile injury patterns that differentiate ischemic coronary artery disease patients who have ischemic MR from those who do not. ⋯ Multiparametric strain analysis demonstrated severe normalized contractile injury in the papillary muscle-related LV subregions in patients with ischemic MR. The mean degree of normalized injury approached 2 standard deviations and was significantly worse than the levels seen in ischemic no-MR patients.

Duodenal ulcers are a major cause of gastrointestinal bleeding after cardiac surgery.
To determine the incidence of gastrointestinal (GI) bleeding in patients after cardiac surgery, assess the perioperative risk factors, and determine the type of GI tract pathology associated with bleeding events. ⋯ Clinical variables can be used to identify patients at high risk for GI bleeding after cardiac surgery. When GI bleeding occurs, the most common cause is duodenal ulceration, which has an association with Helicobacter pylori infection. These findings may provide an opportunity to initiate preoperative preventative strategies.
