Significance of left ventricular clefts—A case report

Abstract

We describe the case of a 48-year-old patient who presented with an out-of-hospital cardiac arrest due to an acute ST-elevation myocardial infarction. Left ventriculography performed during the initial coronary angiography revealed the presence of structural abnormalities in the myocardial wall which subsequently, with the use of contrast echocardiography and cardiac magnetic resonance imaging, were confirmed to represent ventricular clefts. We reviewed the pathophysiological significance of these defects and compared them with similarly looking abnormalities such as aneurysms, pseudoaneurysms, and diverticula. In conclusion, recognition of ventricular clefts is needed to allow clinicians to differentiate them from other myocardial wall defects with different pathological profile and clinical significance.<Learning objective: With emerging techniques in cardiac imaging some cardiac abnormalities such as left ventricular (LV) clefts are recognized more frequently. This case report describes an incidental finding of LV cleft and provides an extensive review of the literature regarding the clinical significance and differential from other similar findings of different pathology. That will help physicians to distinguish these overlapping findings and tailor patients’ management accordingly.>
