Abstract

A method has been developed that combines dual-energy subtraction and tomosynthesis for vessel imaging in intravenous angiography. This paper describes the procedure for doing tomosynthesis on a fan-beam rotational-motion system and gives the point responses of the imaging system. Phantom studies show that dual-energy tomosynthesis improves the visualization of desired vessels lying on a selected plane. The results may be feasible for some applications such as clinical diagnosis of coronary artery diseases.

Repeat right transradial percutaneous coronary intervention in a patient with dextrocardia: the right approach to the right-sided heart.

Dextrocardia (DC) is a rare cardiac condition in which the cardiac location, as well as apex, is rightwardly displaced. As the incidence of atherosclerotic disease is similar to that of the general population, there have been few reports of percutaneous coronary interventions (PCIs) in these patients. Proposed technical strategies for successful angiography and PCI in DC include counter-directional torquing of the catheter, as well as right-left mirror-image inversion angiographic views. All previous reports of DC PCIs have been via transfemoral access.We present a case of successful repeat transradial PCI in a patient with DC. This is first report of transradial coronary angiography, PCI, or repeat PCI in a DC patient. A literature review of technical considerations, including our own recommendations for guide catheter selection, are discussed. We also review the anatomic variations and epidemiology of DC. Although access complications for transradial PCI is known to be lower than that of the transfemoral approach, challenges in technique and concern of repeat access have limited the popularity of the former. Our report demonstrates the safety and feasibility of transradial angiography, PCI, and even repeat PCI, in the rare patient with DC.
