A rare pathology of syncope: A dilemma for hypertrophic cardiomyopathy or right atrial huge thrombosis

Abstract

The complications associated with central venous catheters for hemodialysis access are well known. A rare complication is the development of right-sided intracardiac thrombus, which typically occurs in the right atrium. The location of the permanent catheter tip is associated with the development of thrombi. In this case report, we describe a patient with hypertrophic cardiomyopathy diagnosed with chronic kidney failure 2 years before contrast examination. The patient presented syncope during his last routine hemodialysis, and echocardiography imaging showed a hyperechogenic mass at the tip of the catheter.
