Among diverse triggering factors of stress-induced takotsubo cardiomyopathy (TC), a viral or bacterial infection is rarely observed. Sepsis is an exception, regardless of the etiologic pathogen, in which case an excess of catecholamines may result in acute left ventricular dysfunction. TC precipitated by Clostridium difficile infection (CDI) has been reported only in two patients so far.
A case report: The authors describe another case of TC triggered this time by recurrent C. difficile colitis which occurred in a 72-yearold female. Severe heart failure developed on the second day of a new episode of diarrhea. Echocardiography revealed apical ballooning, a typical form of TC, while the coronary arteries in coronary angiography were normal. Despite proper treatment of CDI, the course of the disease was fatal due to heart failure progression. In considerations of TC pathogenesis in the case presented, the impact of C. difficile toxins should be taken into account. One should remember about the potential extraintestinal complications of CDI, including sudden myocardial depression.
