Project description:BackgroundLeft ventricular pseudoaneurysm is a recognized, however, uncommon presentation of acute myocardial infarction in the current era. This is due to early reperfusion therapy for acute myocardial infarction. Left ventricular pseudoaneurysm after myocardial infarction can present in a variety of ways, including heart failure, chest pain, and dyspnoea.Case summaryWe present a case of a 61-year-old male who presented with extremely atypical symptoms of dysphagia and weight loss due to a massive left ventricular pseudoaneurysm. Transthoracic echocardiogram and computed tomography revealed a large pseudoaneurysm causing mass effect on multiple gastrointestinal organs. Organic causes for dysphagia and weight loss were ruled out by gastroscopy. Surgical management was carried out but was ultimately unsuccessful.DiscussionDespite the heterogeneity in presentation for patients with left ventricular pseudoaneurysm, rapid diagnosis is important for management and prognosis. Diagnostic tools include transthoracic echocardiography, computed tomography, and cardiac magnetic resonance imaging. Management is usually surgical; however, there is some debate in the literature regarding conservative vs. surgical management for chronic pseudoaneurysms. More data are needed to determine optimal management strategies and prognosis for patients with left ventricular pseudoaneurysms.

Case report: pseudoaneurysm of left ventricle secondary to infective endocarditis complicated by cardiac rupture-a multimodality imaging approach.

Project description:BackgroundPseudoaneurysm (PSA) of the left ventricle (LV) is a rare peri-annular complication of infective endocarditis (IE), and it is associated with high risk of free wall rupture. The diagnosis is challenging because the exact incidence and the pathogenesis are still unclear.Case summaryA 69-year-old lady underwent prosthetic mitral valve replacement for IE secondary to Staphylococcus aureus sepsis complicated by multiple embolizations. In the post-operative period, the patient developed persistent low-grade fever with negative blood culture. Transoesophageal echocardiography (TOE) revealed complete posterior valve detachment and a PSA sac arising from the antero-lateral commissure; the colour flow Doppler showed massive mitral regurgitation. Thoracic computed tomography (CT) scan confirmed the echo data and the exact localization of the cardiac rupture. The patient underwent reoperation, a pericardial patch was sutured to exclude the PSA sac, and a mechanical prosthesis valve was finally implanted. A follow-up TOE revealed the exclusion of the PSA; two leakages with mild peri-valvular mitral regurgitation were found, with no haemodynamic impact.DiscussionIn our case, the patient developed a PSA of the LV as a consequence of peri-annular extension of IE on the mitral valve. Pseudoaneurysm is a potentially lethal complication, if not promptly treated. Multimodality imaging including echocardiography and CT scan is recommended, in order to plan surgery ad hoc.

An Unusual Case of Left Ventricular Outflow Tract Pseudoaneurysm.

Project description:Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare condition with a wide range of causes and various clinical outcomes. The causes range from infections, trauma to the chest wall, and iatrogenic origins. We present a unique case of idiopathic LVOT pseudoaneurysm in a patient with no obvious clinical risk factors. (Level of Difficulty: Advanced.).

Left ventricular pseudoaneurysm in Lemierre's syndrome: a case report.

Project description:BackgroundLemierre's syndrome is an infectious phenomenon characterized by oropharyngeal infection with bacteraemia, thrombophlebitis, and distant septic emboli. Septic emboli are a recognized cause of a Type 2 myocardial infarction, with a left ventricular pseudoaneurysm being a rare but important complication of this.Case summaryA 19-year-old male presented with acute confusion, fevers, and a cough. Blood cultures were positive for Fusobacterium necrophorum and initial imaging showed a cavitating pneumonia. Further evaluation revealed septic emboli in the distal digits and brain. The patient initially responded to antibiotic therapy but developed chest pain with increased troponin levels. An electrocardiogram showed inferolateral ST elevation. A transthoracic echocardiogram (TTE) showed hypokinaesia of the mid to apical lateral wall, and a computed tomography (CT) scan showed a pericardial effusion with a possible purulent effusion or abscess. The patient underwent surgical drainage of a sterile effusion. A post-operative TTE and CT demonstrated a left ventricular pseudoaneurysm that was surgically repaired. The venous thrombus was encountered intra-operatively confirming a diagnosis of Lemierre's syndrome. The patient completed the regimen of antibiotics and showed a good post-operative recovery.DiscussionThis is the first case described of left ventricular pseudoaneurysm as a complication of Lemierre's syndrome. It highlights not only the importance of serial, multimodality imaging in both diagnostic workup and identification of complications, but also the importance of a multidisciplinary team in the management of patients with complex and rare presentations.
