Pulmonary vein ostium geometry: analysis by magnetic resonance angiography.
BACKGROUND During a catheter ablation procedure for selective electrical isolation of pulmonary vein (PV) ostia, the size of these ostia is usually estimated using fluoroscopic angiography. This measurement may be misleading, however, because only the projected supero/inferior ostium diameters can be measured. In this study, we analyzed 3-dimensional magnetic resonance angiographic (MRA) images...
متن کاملDiagnosis of pulmonary embolism with magnetic resonance angiography.
BACKGROUND Diagnosing pulmonary embolism may be difficult, because there is no reliable noninvasive imaging method. We compared a new noninvasive method, gadolinium-enhanced pulmonary magnetic resonance angiography, with standard pulmonary angiography for diagnosing pulmonary embolism. METHODS A total of 30 consecutive patients with suspected pulmonary embolism underwent both standard pulmona...
متن کامل[Morphologic study of the pulmonary veins by magnetic resonance angiography].
Accurate knowledge of the anatomy of the pulmonary veins is important in clinical electrophysiology. In order to evaluate the usefulness of magnetic resonance angiography for this purpose, we studied 17 unselected patients. All the pulmonary veins were visualized in each individual. The diameters of the ostia ranged between 9 mm and 22 mm. The cross-section of the ostium was elliptical in 35% o...
