Diagnostic Yield of Electroanatomic Voltage Mapping in Guiding Endomyocardial Biopsies

Comparison of electroanatomic voltage mapping with late gadolinium enhancement CMR

Background Atrial fibrillation (AF) is associated with atrial remodeling, including atrial cellular pathology [1,2], left atrial enlargement [3], and low voltage on electroanatomic mapping (EAM)[4]. Recent studies have identified late gadolinium enhancement (LGE) in AF subjects pre-PVI as novel evidence of LA remodeling [5]. One study compared voltage by EAM obtained prior to a pulmonary vein i...

Diagnostic yield by multiple biopsies in malignant pleural effusion.

Principles of Electroanatomic Mapping

Electrophysiologic testing and radiofrequency ablation have evolved as curative measures for a variety of rhythm disturbances. As experience in this field has grown, ablation is progressively being used to address more complex rhythm disturbances. Paralleling this trend are technological advancements to facilitate these efforts, including electroanatomic mapping (EAM). At present, several diffe...

Diagnostic yield and complications of transthoracic computed tomography-guided biopsies.

INTRODUCTION The widespread use of computed tomography (CT) improves detection of pulmonary lesions, which are not only detected at an increased rate but also at a smaller size. CT-guided lung biopsies are now more frequently used than fluoroscopy-guided lung biopsies. The main aim of the present paper was to investigate the outcome and complications of the biopsies. METHODS We retrospectivel...

Diagnostic yield of biopsies via fibre-optic bronchoscopy.

BACKGROUND Priority of all bronchoscopies has been diagnostic yield and various techniques have been introduced to improve it. Transbronchial biopsy (TBB) and transbronchial aspirates (TBA) also play an important role in improving diagnostic yield. The aim of the study was to determine the diagnostic yield of biopsies via fibre optic bronchoscopy (FOB) in 108 cases in which it was indicated. ...
