Technical developments in cardiac CT: 2000 update.

Abstract

Preliminary results of the new generation CT scanners in the study of the heart and coronary arteries, are reported, after an overview of basic anatomy, physiology and main technical problems. Comparison is made with the other conventional procedures. The clinical validation of cardiac CT is under way while preliminary results are very encouraging. However, for cardiac CT to become an examination of first choice in the study of the heart and coronary arteries, spatial resolution should be improved and acquisitions of 15 cm volume with less than 15 sec breath-hold should be feasible. The improvement in cardiac synchronization and temporal resolution will allow a kynetic systolic as well as diastolic study. This is going to be possible with the new generation CT scanners able of 16 or 32 sections per second.

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.
