Optimal cut-off value for cardiac troponin I in ruling out Type 5 myocardial infarction.
The clinical classification of myocardial infarction (MI) into five types was introduced in 2007 as a component of the universal definition. A Type 5 MI was defined as a MI related to coronary artery bypass surgery. In a setting of patients undergoing elective coronary artery bypass grafting, we set out (i) to describe the pattern of multiple serial cardiac troponin I (cTnI) measurements within 72 h postoperatively and (ii) to determine the optimal cardiac troponin I cut-off value in ruling in or ruling out a Type 5 MI. ⋯ In clinically stable patients undergoing elective coronary artery bypass grafting, measurements of cTnI are useful in ruling out a Type 5 MI.

Artificial chordae in the setting of complex mitral valve repair: early outcomes using the folding leaflet technique.
Neochordal repair is particularly limited in case of large prolapse with absence of a reference point on a nearby segment. Our aim was to overcome these limitations by means of a simple technique: the 'Folding Leaflet'. ⋯ MV repair for complex degenerative MR using this technique of neochordal repair results in excellent early and mid-term outcomes. This technique facilitates the extensive use of neochordae in case of large areas of prolapse.

Comment Case ReportsIntraoperative management of failed single lung ventilation using a Fogarty balloon catheter through the open bronchus during off-pump left lung transplantation.
The use of balloon catheters as an interventional procedure is well established in various fields of medicine. Failure of single lung ventilation (SLV) can add difficulty to open bronchus procedures, and could result in a life-threatening situation very quickly. Trying to achieve single lung ventilation by alternate methods is fraught with dangers, and use of urgent cardiopulmonary bypass is less desirable because of increased primary graft dysfunction and mortality. We describe a novel approach of using a Fogarty balloon catheter through the open bronchus to achieve SLV during off-pump left lung transplantation when conventional SLV failed.
