Visualization of coronary venous anatomy by cardiovascular magnetic resonance
BACKGROUND Coronary venous imaging with whole-heart cardiovascular magnetic resonance (CMR) angiography has recently been described using developmental pulse sequences and intravascular contrast agents. However, the practical utility of coronary venous imaging will be for patients with heart failure in whom cardiac resynchronisation therapy (CRT) is being considered. As such complementary infor...
متن کاملEvaluation of Coronary Venous Anatomy by Multislice Computed Tomography
Background: The coronary venous system is increasingly targeted for pacing in patients with severe heart failure. The recent advancement of Multi-Detector Computed Tomography (MDCT) allows accurate analysis of the coronary arteries, but little data exist on its role in assessing cardiac venous anatomy. The aim of the present study was to investigate the feasibility of using MDCT in evaluating t...
متن کامل[Coronary angiography: beyond coronary anatomy].
Although technical advances enable normal epicardial coronary artery blood flow to be restored in most patients suffering myocardial infarction, restoration of blood flow is not always followed by improved myocardial perfusion. Recently, therefore, interest in the assessment of myocardial perfusion has grown, and a number of different assessment methods are available. The aim of this article wa...
متن کاملUsefulness of hyperemic venous return angiography for studying coronary venous anatomy prior to cardiac resynchronization device implantation.
INTRODUCTION AND OBJECTIVES Implantation of electrodes via the coronary sinus (CS) can be very challenging because access to the target vessel is restricted by anatomical obstacles. Consequently, prior knowledge of coronary venous anatomy is crucial. The objective of this study was to evaluate the usefulness of hyperemic venous return angiography relative to that of occlusive retrograde venogra...
متن کامل[Double-wire technique for implanting a left ventricular venous lead in patients with complicated coronary venous anatomy].
INTRODUCTION AND OBJECTIVES Occasionally, implanting a left ventricular pacing electrode for cardiac resynchronization therapy via the coronary sinus may be complicated by the presence of anatomical structures that obstruct the access to the target vein. Our objective was to report on experience using a double-wire technique for implanting left ventricular venous leads gained at the Dr Negrín H...
