Case ReportsMinimally invasive direct coronary artery bypass grafting using the saphenous vein in redo CABG.
We describe a patient who underwent minimally invasive direct coronary artery bypass (MIDCAB), who had previously undergone coronary artery bypass grafting (CABG) through a median sternotomy with a left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD) and a right gastroepiploic artery (GEA) graft to the posterior descending artery. MIDCAB was less invasive and was an effective alternative procedure for the second operation. ⋯ The SVG-to-coronary artery anastomosis was facilitated by firm adhesion between the epicardium and the pericardium, which reduced the motion of the epicardium itself. These results suggest that the procedure is safe and promising in selected cases of redo CABG.

Comparative StudyIntramyocardial electrogram recordings (IMEG) for diagnosis of cellular and humoral mediated cardiac allograft rejection.
The purpose of this study was to prove the reliability of intramyocardial electrogram (IMEG) recordings for diagnosis and treatment monitoring of (1) cellular and (2) humoral mediated allograft rejection after heart transplantation. ⋯ The IMEG detects cellular and humoral mediated rejection early and with high reliability. The rejection-related changes of grade 2/3a rejection in IMEG seem to follow a Ofocal patternO similar to the histology. Therefore the recording of several, preferably bipolar, electrode configurations appears to enhance diagnostic reliability.
