Project description:Left ventricular pseudoaneurysm is an uncommon complication after transmural myocardial infarction, occurring when a free wall rupture is contained by adhesions of the overlying pericardium preventing acute tamponade. In this report, an unusual case of a 61 year-old male with a giant apical left ventricular pseudoaneurysm after an unnoticed myocardial infarction is presented. On coronary angiogram myocardial bridging of the distal left anterior descending artery was judged to be the infarct related lesion. The echocardiographic diagnosis allowed for a timely surgical intervention which resulted in the patient's full recovery.

Left ventricular pseudoaneurysm complicating inferior myocardial infarction: a case report.

Project description:Acquired pseudoaneurysm of the left ventricle is a very rare disorder and mostly occurs after large transmural myocardial infarction (MI) with peak creatine phosphokinase-MB levels greater than 150 IU/mL. Patients developing left ventricular (LV) pseudoaneurysm usually present with angina or heart failure symptoms. Although different imaging modalities exist, coronary angiography is the gold standard for diagnosis. Surgery is the treatment of choice for LV pseudoaneurysms detected in the first months after MI. Here we report the case of a 74-year-old woman who presented with a relatively small inferior MI due to right coronary artery occlusion and complicated by LV pseudoaneurysm.

Left ventricular pseudoaneurysm after myocardial infarction detected by cardiac MRI.

Project description:Left ventricular free wall rupture (LVFWR) is a grave complication of acute myocardial infarction. Acutely, it has an extremely high rate of mortality, especially if undetected. Chronically, there is paucity of data on how to manage the pathology, especially if detected as an incidental finding. We present a unique case of initially undetected LVFWR in a patient who presented with repeated chest pain. Cardiac MRI enabled the diagnosis and localisation of the original site of LVFWR and provided highly relevant volume calculations. Measurement of both absolute and virtual volumes indicated that aneurysm resection, including the original site of rupture, was surgically feasible without reducing postoperative stroke volume.

Thrombosed left ventricular pseudoaneurysm following myocardial infarction: a case report.

Project description:BackgroundPseudoaneurysm of inferior wall of the left ventricle is an uncommon complication of myocardial infarction with high mortality.Case presentationWe report the case of a 63-year-old Tunisian man, diagnosed with a thrombosed left ventricular pseudoaneurysm and a pericardial effusion after 1 week of angina.ConclusionsLeft ventricular pseudoaneurysm is a serious complication of myocardial infarction that has atypical presentations. Diagnosis is generally established by transthoracic echocardiography but confirmed by magnetic resonance imaging. Urgent surgery is the treatment choice given the risk of embolization and rupture.

Transatrial repair of a giant left ventricular pseudoaneurysm and ischaemic mitral regurgitation after myocardial infarction: case report.

Project description:Left ventricular pseudoaneurysm (LVPA) is an infrequent but highly lethal complication of myocardial infarction. Early surgical repair with a resection of pseudoaneurysm is often performed, given that medical therapy alone is associated with a high risk of mortality. This report describes a case of a giant LVPA on the lateral wall post-infarction and mitral valve regurgitation that was successfully treated by surgical transatrial closure and mitral valve replacement. A 77-year-old man with chronic kidney disease and a history of percutaneous coronary interventions for acute myocardial infarction was referred to the cardiac surgeons because of a spontaneous finding of an abnormal mass adjacent to the heart on imaging studies, which was missed on a chest radiograph obtained 3 months earlier. Cardiac studies revealed LVPA and severe mitral regurgitation with poor ejection fraction. Early repair of LVPA and concurrent mitral valve surgery were recommended. Transatrial patch closure and mitral valve replacement were performed using an interatrial approach via median sternotomy. Although the patient's post-operative course was complicated by congestive heart failure and irreversible renal failure, he was discharged with good functional status after 1 month of intermittent renal replacement therapy with haemodialysis. Transatrial repair of LVPA and concurrent mitral valve replacement can be a treatment of choice for reducing surgical trauma to the left ventricle and protecting the sealing structure from rupture.

Left ventricular restoration devices post myocardial infarction.

Project description:Even in the era of percutaneous reperfusion therapy, left ventricular (LV) remodeling after myocardial infarction (MI) leading to heart failure remains a major health concern. Contractile dysfunction of the infarcted myocardium results in an increased pressure load, leading to maladaptive reshaping of the LV. Several percutaneous transcatheter procedures have been developed to deliver devices that restore LV shape and function. The purposes of this review are to discuss the spectrum of transcatheter devices that are available or in development for attenuation of adverse LV remodeling and to critically examine the available evidence for improvement of functional status and cardiovascular outcomes.

Giant Left Ventricular (Pseudo?) Aneurysm Complicating Anterior Myocardial Infarction.

Project description:The differential diagnosis of true aneurysms and pseudoaneurysms is challenging, and multimodality cardiac imaging is often necessary. We report a case in which the limitations of these techniques are exposed, showing that post-operative evaluation of tissue layers remains the gold standard in establishing this diagnosis. (Level of Difficulty: Beginner.).
