Remarkable thickening of right atrial wall in subjects with cardiac amyloidosis complicated with sick sinus syndrome.
We observed a 63-year old male with cardiac amyloidosis who presented with the clinical symptoms of sick sinus syndrome and dyspnea and abnormal thickening of the right atrial wall, which extended to the junction of the superior vena cava. This may explain the relationship of abnormal thickening of the right atrium which extends to the junction of the superior vena cava and right atrium with amyloid deposits in the sinus node and occurrence of sick sinus syndrome.
