Hypereosinophilic syndrome (HES) is a rare disorder characterised by eosinophilic infiltration of tissues. Myocardial infiltration occurs in 50%–60% of HES and leads to a condition called Loeffler’s endocarditis. This can lead to endomyocardial injury with resultant superimposed thrombus formation and embolic stroke. We describe the case of a 57-year-old female patient presenting with neurological symptoms who was found to have multiple embolic strokes on a background of long-standing eosinophilia. Following a series of investigations, including transthoracic and transoesophageal echocardiographies and cardiovascular MRI, she was confirmed to have Loeffler’s endocarditis with left ventricular thrombus. She was treated successfully with steroids and anticoagulation. We describe the pathophysiology of HES and Loeffler’s endocarditis and stress the crucial role of multimodality cardiac imaging in establishing its diagnosis and treatment monitoring.

SummaryLeft ventricular thrombus (LVT) and rupture are important mechanical complications following myocardial infarction (MI) and are believed to be due to unrelated mechanisms. We studied whether, in fact, wall rupture and LVT are closely related in their pathogenesis with intramural platelet thrombus (IMT) playing a pivotal role. Male 129sv and C57Bl/6 mice underwent operation to induce MI, and autopsy was performed to confirm rupture deaths. Haemodynamic features of rupture events were monitored by telemetry in conscious mice. Detailed histological examination was conducted with special attention to the presence of IMT in relation to rupture location and LVT formation. IMT was detected in infarcted hearts of 129sv (82%) and C57Bl/6 (39%) mice with rupture in the form of a narrow streak spanning the wall or an occupying mass dissecting the infarcted myofibers apart. IMT often contained dense inflammatory cells and blood clot, indicating a dynamic process of thrombus formation and destruction. Notably, IMT was found extending into the cavity to form LVT. Haemodynamic monitoring by telemetry revealed that rupture occurred either as a single event or recurrent episodes. Importantly, the anti-platelet drug clopidogrel, but not aspirin, reduced the prevalence of rupture (10% vs. 45%) and IMT, and suppressed the degree of inflammation. Thus, IMT is a key pathological element in the infarcted heart closely associated with the complications of rupture and LVT. IMT could be either triggered by a wall tear or act as initiator of rupture. IMT may propagate towards the ventricular chamber to trigger LVT.

ABSTRACT Systolic anterior motion (SAM) of the mitral leaflets can lead to hemodynamic instability in post bypass period. Perioperative transesophageal echocardiography (TEE) plays a crucial role in the management of SAM. Perioperative echocardiography helps to (a) identify cause of left ventricular outflow tract obstruction, (b) assess SAM and diagnose severity and (c) management of SAM. A case is presented illustrating identification and management of SAM in post bypass period. How to cite this article Kumar A, Rajkumar V, Kumar A, Puri GD. Role of Perioperative TEE in Diagnosing and Management of a Case of Dynamic LVOT Obstruction/SAM. J Perioper Echocardiogr 2015;3(2):58-61.
