Stereotaxis: A New Approach for Treating Highly Tortuous and Angulated Coronay Lesions After Conventional Techniques Have Falled

Multilateralism after the Failure of the DDR and Climate Change Negotiations

 This paper examines the two most important current efforts to devise new rules binding all nations the negotiations in the WTO of trade rules and the negotiations under the UN Framework Convention on Climate Change to devise rules restricting the annual emissions of greenhouse gases. Both negotiations have failed after several years of intensive effort. There are remarkable parallels in these ...

Successful Rotational Atherectomy for an Angulated Calcified Lesion in an Anomalous Right Coronary Artery Using the “Mother-and-Child” Technique

Percutaneous coronary intervention (PCI) involving the anomalous coronary artery is challenging with respect to difficulty in achieving stable catheterization. Rotational atherectomy (RA) can facilitate severely calcified lesions to improve stent delivery and stent expansion; however, its utility in tortuous and angulated coronary arteries is limited with difficulty in delivery of the RA burr. ...

Initial experience with a magnetic navigation system for percutaneous coronary intervention in complex coronary artery lesions.

OBJECTIVES The aim of this study was to evaluate the feasibility of a magnetic-assisted navigation system during percutaneous coronary intervention (PCI) of tortuous and severely angulated coronary arteries. BACKGROUND The magnetic navigation system consists of two 0.8-T permanent magnets which generate a magnetic field over the heart. Altering the magnetic vector deflects a coronary guidewir...

Artefactual angulated lesion on angiography: A case report and review of literature

We present a case of a patient who presented with chest pain, and on diagnostic coronary angiography appeared to have a grossly angulated yet significant coronary stenosis. This was proven to be an artefactual appearance on further assessment with intravascular ultrasound imaging. We describe the causes and associations of coronary tortuosity with other arteriopathy, and highlight challenges in...
