Gated cardiac blood pool studies in arrhythmias
- 1. Centre Hospitalier Universitaire Trousseau, 37 - Tours (France)
Description
Biventricular phase analysis a gated blood pool studies may help to solve two fundamental questions raised by patients suffering from arrhythmias: localization of an electrical cardiac activation abnormality by means of contraction mapping and assesment of an underlying organic disease using the phase histograms and their standard deviations. Three groups of patients have been evaluated to demonstrate the usefulness of radioisotopic techniques in arrhythmias: 36 patients with a Wolff-Parkinson-White syndrom, 27 patients studied during a ventricular tachycardia attack and 32 patients suspected of arrhythmogenic ventricular dysplasia. Correlations with invasive electrophysiologic studies are presented and the diagnostic and therapeutic implications of these results are discussed
Abstract (French)
L'etude de la dynamique de contraction des cavites cardiaques, avec analyse de phase biventriculaire, peut aborder deux questions fondamentales que l'on se pose en presence de sujets porteurs de troubles du rythme: la localisation d'une anomalie de l'activation electrique a partir de la cartographie de contraction et la demonstration d'une cardiopathie organique sous-jacente au moyen des histogrammes de phase et de leurs deviations standard. Trois groupes de patients illustrent l'apport des isotopes en rythmologie: 36 patients porteurs d'un syndrome de Wolff-Parkinson-White, 27 patients enregistres en cours de tachycardie ventriculaire et 32 patients suspects de dysplasie ventriculaire arythmogene. Les correlations avec l'electrophysiologie endocavitaire ainsi que les apports diagnostiques et therapeutiques de ces resultats sont presentesAdditional details
