Coronary artery bypass grafting versus percutaneous coronary intervention in single-vessel left anterior descending artery disease: mid-term propensity matching study.

Introduction: Coronary artery bypass grafting (CABG) has been considered to be the proven therapeutic choice for coronary artery disease. However, percutaneous coronary intervention (PCI) with drug-eluting stents is increasingly used for extensive coronary artery disease with contradictory results. The aim of this study is to compare immediate- and mid-term results of CABG where skeletonized internal mammary artery (IMA) was used as in situ graft versus PCI with serolimus drug eluted stents (SES) in single-vessel left anterior descending artery (LAD) disease.

Clipless skeletonized internal mammary artery harvesting with harmonic technology.

Since the introduction of the mammary artery harvesting procedure, electrocautery has been used as a standard method of care. However, mammary artery spasm, subadventitial haematoma and mammary artery damage due to clips dispositioning or high thermal energy injury have been recorded. To achieve a perfect mammary artery graft, we propose the usage of a high-frequency ultrasound device, usually recognized as a harmonic scalpel.

Heavy metals and acidic components in total deposited matter in Sibenik and National Park Kornati, Croatia.

This article presents the results of 6 years (1999-2004) of monitoring acidic components (fluoride, chloride, nitrate, sulfate) and heavy metals (lead, cadmium, thallium) in total deposited matter (TDM) in the town of Sibenik and the National Park Kornati, Croatia, in order to determine their levels, spatial and temporal variations, and possible emission source. Bulk deposition samples were collected using the Bergerhoff samplers. TDM matter was determined gravimetrically.
