Introduction: Pseudoaneurysm may occur as a rare complication of myocardial infarction (MI) when a hemorrhagic process is covered by adherence of the visceral or parietal pericardium or of both, preventing the formation of cardiac tamponade. Pseudoaneurysm is prone to rupture because they are not easy to diagnose. Case presentation: Here, we report three cases of left ventricular pseudo-aneurysm (LVP) that all were related to MI. Two patients were managed conservatively, one of them was lost to follow-up, and the other one expired one month later. One patient underwent surgery, but he expired during post-operation period. Conclusions: High mortality rate of LVP emphasizes the importance of looking for it in cardiac evaluation of patients with history of MI. Due to available non-invasive modalities, the ability to differentiate LVP from other cardiac pathologies is improving. Still, the most recommended management of LVP is early surgery.

Highlights: Left ventricular pseudoaneurysms are a rare mechanical complication of myocardial infarction. If found acutely following infarction (within 2 weeks, with some advocating up to 3 months), surgical repair is recommended due to their high risk of rupture.Whilst associated with chest pain, dyspnoea and heart failure, some individuals are asymptomatic, with the diagnosis made incidentally on routine follow-up often months to years post infarction. Less is known about the natural history of these chronic pseudoaneurysms, with concerns around their propensity to rupture perhaps less than the mortality risk of surgical repair.We present the case of a 70 year-old asymptomatic man who was found to have a 1.6cm left ventricular pseudoaneurysm found incidentally on routine transthoracic echocardiogram. at 12-months post posterior myocardial infarctionThe consensus opinion of our institution's multi-disciplinary team regarding further management of this patient, with reference to the current limited data on chronic pseudoaneurysms, will be discussed.

Abstract Background Saw tooth cardiomyopathy (STC) is an unusual type of left ventricular dysplasia. To our knowledge, six cases have been reported in the literature. Two new cases are presented with a review of all the case reports that have been published. Case summaries Two patients with STC were examined. The first one was a 69-year-old woman with shortness of breath on mild exertion and chest pain, and the second was a 49-year-old man with a history of myocardial infarction who required stent implantation and is now asymptomatic. Both patients revealed findings of STC in the cardiac CT. Discussion When analyzing the cases and comparing them to the ones reported in literature; STC is a generally benign heart disease, although the clinical spectrum can range from asymptomatic to heart failure. Imaging studies such as CMR and cardiac CT are essential for the diagnosis.

Abstract Background Intramyocardial dissecting haematoma is a rare complication of myocardial infarction (MI) associated with high mortality rates. Studies and research of this occurrence are limited largely to isolated case reports or case series. Case summary We report a case of late presenting MI, where on initial echocardiogram had what was thought to be an intraventricular clot. However, upon further evaluation, the patient actually had an intramyocardial haematoma, with the supporting echocardiographic features to distinguish it from typical left ventricular (LV) clot. While this prevented the patient from receiving otherwise unnecessary anticoagulation, this diagnosis also put him at a much higher risk of mortality. Despite exhaustive medical and supportive management, death as consequence of pump failure occurred after 2 weeks. Discussion This report highlights the features seen on echocardiography which support the diagnosis of an intramyocardial haematoma rather than an LV clot, notably the various acoustic densities, a well visualized myocardial dissecting tear leading into a neocavity filled with blood, and an independent endocardial layer seen above the haematoma. Based on this report, we wish to highlight the importance of differentiating intramyocardial haematomas from intraventricular clots in patients with recent MI.

Abstract Background Left ventricular pseudoaneurysm is a very rare complication following acute myocardial infarction, which results from a free wall rupture. Hemopericardium and cardiac tamponade caused by rupture of the free wall after acute myocardial infarction are often fatal. It is difficult to fully document the evolution of left ventricular pseudoaneurysm resulted from acute myocardial infarction with conservative treatment. Case presentation Herein, we followed a 75-year-old female patient for 3 years. Recorded the evolution of the disease: acute lateral myocardial infarction - emergency reperfusion therapy - cardiac rupture - positive successful rescue - the pseudoaneurysm formation - maintaining conservative treatment - gradual enlargement of the pseudoaneurysm - thrombosis in pseudoaneurysm - thrombus filling with pseudoaneurysm - finally stabilized condition - the treatment of coronary revascularization. Conclusions This case is reported here because of its scarcity, which provides provides us with a complete record of the entire evolution and an astonishing indication of the long-term prognosis of non-surgical treatment for pseudoventricular.

Acute Mi

Left ventricular pseudoaneurysm (LVPA) is a rare complication of acute myocardial infarction (MI). As pseudoaneurysm is contained by the pericardium alone without involvement of myocardial tissue, LVPA are more prone to rupture and hence necessitates surgical intervention. We report a case of a 60-year-old man with acute MI due to a three-way occlusion in the coronary arteries. An emergency transthoracic echocardiogram (TTE) on the 11th day after the MI showed a small ventricular aneurysm, which was probably a late complication of the acute MI episode. A repeat TTE on the 26th day of the MI episode revealed a rapidly progressing LVPA. Emergency heart surgery was planned, but the patient died due to LVPA rupture. This case illustrates timely diagnosis and corrective surgery are key to saving patients from fatal LVPAs
