Left atrial, pulmonary vein and dural calcification in a patient with arrhythmia and chronic renal failure.

Left atrial and dural calcification in chronic renal failure is very rare. Massive atrial calcification can lead to arrhythmia and diagnosis of this condition is important to take prophylactic measures in dialysis patients. Noninvasive diagnosis of left atrial calcification is also important as it can complicate valvular surgery. We report on a patient with chronic renal failure presenting with arrhythmia in whom left atrial calcification involving interatrial septum is diagnosed by thorax CT examination.
