Right atrial abscess: An unusual complication of intravascular catheter uncovered by transesophageal echocardiography

Abstract

Perivalvular myocardial abscess is a well-known complication of valvular infective endocarditis (IE) (1). Here, we present an absolutely rare case of right atrial (RA) wall abscess accompanying tricuspid valve (TV) IE which was only revealed by transesophageal echocardiography (TEE). The patient was an end-stage renal disease (ESRD) case who was receiving hemodialysis (HD) via a dual-lumen cuffed venous catheter. The unique feature of this case is the anatomical location of the abscess in the RA wall as well as multiple septic vegetations distant from the TV.
