Chronic kidney disease is a significant risk factor for mortality as well as acute kidney injury in cardiac surgery. The impact of contrast agent application on outcome is not well described in patients undergoing transcatheter aortic valve implantation. ⋯ Preoperative chronic kidney disease does not increase the risk of mortality and acute kidney injury after transcatheter aortic valve implantation. Acute kidney injury after TAVI is associated with an elevated risk of mortality. The amount of contrast agent applied intra-procedurally does not affect the risk of acute kidney injury.

Within the group of patients undergoing coarctectomy today, two subgroups can be identified: neonates with a critical coarctation and nonneonatal patients. We hypothesize that patients who have to undergo repair in the neonatal period will have more persistent impairment of ventricular performance postoperatively. Accordingly, we aimed to characterize biventricular performance after coarctectomy in neonatal and nonneonatal patients. ⋯ In both subgroups, LV diastolic performance does not recover to normal values within the first postoperative year. However, LV systolic performance remains more persistently impaired in patients who have to undergo repair in the neonatal period vs nonneonatal repair.

Coronary artery bypass grafting (CABG) is a well-established procedure for treating diabetic patients with multivessel disease, but extracorporeal circulation and cardioplegia-induced cardiac arrest introduce a severe burden to these patients. The present study investigated if off-pump CABG decreases 30-day mortality and mid-term mortality in diabetic patients in comparison with conventional CABG. ⋯ Our data indicate that in terms of postoperative complications and early and mid-term survival, off-pump CABG is superior to the on-pump technique in diabetic patients.

Comparative Study
Surgical biopsy of suspected interstitial lung disease is superior to radiographic diagnosis.
Different modalities are used to diagnose interstitial lung disease. We compared the effectiveness of minimally invasive surgical biopsy versus high-resolution computed tomography for the diagnosis of interstitial lung disease and report the mortality of the procedure. ⋯ Surgical biopsy should remain the gold standard for diagnosis of interstitial lung disease. The mortality is low with proper patient selection. More than two surgical biopsy specimens may not be needed because the concordance rates among pathologic specimens are very high.

Case Reports
Thoracoscopic lobectomy for synchronous intralobar pulmonary sequestration and lung cancer.
Bronchopulmonary sequestration is a rare congenital pulmonary malformation for which surgical resection is recommended, and several reports have described successful resection by video-assisted thoracoscopic surgery. Coexistence of sequestration with lung malignancy is extremely rare. We report the first case of thoracoscopic resection of synchronous intralobar pulmonary sequestration and non-small cell lung cancer.
