Remote-control percutaneous coronary interventions: concept, validation, and first-in-humans pilot clinical trial.

Objectives: This study was designed to assess the feasibility and safety of a Remote Navigation System (RNS, NaviCath, Haifa, Israel) in which the angioplasty guidewire, the balloon, and the stent are navigated via a computerized system.

Background: Percutaneous coronary interventions (PCIs) are manually performed under fluoroscopic guidance, requiring lead protection for the operators. A system in which the operator can remotely, safely, and precisely navigate the procedure during PCI would have clear advantages.

Haptoglobin phenotype and coronary artery collaterals in diabetic patients.

Cross-cultural epidemiological studies of incident cardiovascular disease in the diabetic patient have demonstrated marked differences in susceptibility that may be due to a genetic factor. The coronary artery collateral circulation is the chief determinant of the size of a myocardial infarction and is highly variable between patients. We recently demonstrated that a functional allelic polymorphism in the haptoglobin gene is correlated with a number of diabetic vascular complications.

Stenting very small coronary narrowings (< 2 mm) using the biocompatible phosphorylcholine-coated coronary stent.

Published data regarding stenting very small arteries are still limited. The BiodivYsio stent is a new stent coated with phosphorylcholine, a biocompatible molecule designed to reduce the formation of thrombus and potentially the risk of restenosis. The feasibility, safety, and efficacy of implantation of the 2.
