Integration einer präinterventionellen Computertomografie des Herzens in die therapeutische Pulmonalvenenisolation bei Patienten mit paroxysmalem Vorhofflimmern

Abstract

CT-guided ablation of atrial fibrillation requires less fluoroscopy time than stand-alone PVI. Due to the multi-faceted dependency of individual fluoroscopy doses, a consistent reduction of the effective dose was not observed. Since supplementary CT constitutes an additive dose, optimized CT atriography needs to be designed in order to provide sufficient image quality while reducing X-ray exposure. The reduction in RF pulses implies an increase in the effectiveness and safety of catheter ablation.

Strategies for Dose-Optimized Imaging in Pediatric Cardiac Dual Source CT

“…Morphological and functional echocardiographic assessment of an entire congenital repair procedure, which may include extra anatomic bypasses or systemic shunts, is often suboptimal. Central pulmonary arteries are visible, and there is a limited possibility for imaging the peripheral pulmonary arterial or venous vasculature [2]. Also, the airways and lung parenchyma cannot be sufficiently examined.…”
