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.).

Giant lateral left ventricular wall aneurysm sparing the submitral apparatus.

Project description:Left ventricular aneurysms are a frequent and serious complication following acute transmural myocardial infarction and are most commonly located at the ventricular apex. The majority of these patients presents with severe mitral insufficiency, congestive heart failure, systemic embolism and sudden cardiac death. Giant aneurysms occurring in a submitral position between anterior and posterior papillary muscles on the lateral ventricular wall constitute a minor entity and those leaving the mitral apparatus intact are extremely rare.Herein, we report the case of a 57 y/o Caucasian male patient with a past medical history of coronary artery disease and myocardial infarction with a giant left ventricular aneurysm measuring 15x10x8 cm in diameter. Despite the size of the aneurysm and its close topographical relation to the posterior mitral annulus the mitral apparatus was intact with a competent valve and normal left atrial size. He underwent successful surgical ventricular restoration.

Rare case of a giant thrombosed left anterior descending coronary artery aneurysm.

Project description:BackgroundCoronary artery aneurysms (CAAs) are rare, and giant CAAs are even rarer. The pathophysiology of this phenomenon is still unknown.Case presentationHerein, we present the case of a 49-year-old male with a giant aneurysm in the left anterior descending artery.ConclusionsThe optimal treatment for CAAs is debatable, but surgical intervention is preferred for giant CAAs.

Giant left ventricular pseudoaneurysm: a rare acute complication of radiofrequency catheter ablation for premature ventricular contraction.

Project description:BackgroundRadiofrequency catheter ablation is approved effective therapy for premature ventricular contraction. However, the rare but serious complication such as pseudoaneurysm should be given more attention. It is life-threatening due to the high risk of rupture. Only few cases have been reported in the literature. We herein report a huge acute left ventricular pseudoaneurysm after catheter ablation therapy.Case presentationA 69-year-old man underwent radiofrequency catheter ablation for premature ventricular contraction at a local hospital. The patient developed shock the second day after ablation. A chest computed tomography (CT) scan showed pericardial effusion. Pericardiocentesis was performed, and the puncture fluid was a bloody pericardial effusion. The transthoracic echocardiogram revealed an 9- × 4-cm giant pseudoaneurysm with a cystic structure in the left ventricular inferior wall near the mitral annulus along the left atrium. The pseudoaneurysm was connected to the left ventricular cavity through a 8-mm neck, and the lumen was filled with systolic and diastolic blood flow. The patient underwent three-dimensional transesophageal echocardiography. The pseudoaneurysm and the tract was clearly visible. Emergency surgery was performed to resect the pseudoaneurysm. A bovine pericardial patch was placed on the neck of the pseudoaneurysm. Echocardiographic examination confirmed the absence of cardiac lesions after the operation.ConclusionsIt is rare to see such a large pseudoaneurysm after radiofrequency catheter ablation. Clinicians should be allert to the potential risks to patients in the process of an effective treatment. Echocardiography plays an important role in the prompt diagnosis and prognosis of this disease. Emergency surgery is a better method for treatment of huge pseudoaneurysm.

Large inferolateral left ventricular aneurysm.

Project description:The majority of cardiac left ventricular aneurysms involve the anterior and/or apical wall. We present a case of a 50-year-old man with heart failure caused by a large inferolateral left ventricular aneurysm and associated mitral regurgitation, managed by aneurysmectomy, mitral valvuloplasty, and surgical revascularization.

A left ventricular true aneurysm.

Project description:True ventricular aneurysm is a scarred wall that most commonly results after an unrevascularized ST elevation myocardial infarction. Patients usually present with heart failure, angina, ventricular arrhythmia, systemic embolization, or ventricular rupture. Diagnosis can be achieved via echocardiography, left ventricle angiogram, cardiac computed tomography, or cardiac magnetic resonance.

Idiopathic 'True' Left Ventricular Aneurysm.

Project description:We report the case of a 67-year-old patient who presented with anginal symptoms to the hospital. Computed tomographic angiography, to rule out a pulmonary embolism, showed a left ventricular apical outpouching. The patient underwent further imaging modalities, including contrast echocardiography (TTE) and cardiovascular magnetic resonance imaging (CMR), which were suggestive of a true left ventricular aneurysm (LVA). The absence of obstructive coronary artery disease on coronary angiography, absence of late enhancement on the CMR, and ultimately the intraoperative findings during surgical resection of the aneurysm, were strong indicators of a non-ischemic etiology of the patient's LVA. Additionally, the patient denied any previous history of cardiac instrumentation to rule out iatrogenic causes of LVA and congenital causes were excluded by a previous echocardiogram. Finally, history and presenting electrocardiogram did not reveal any other underlying obvious causes for the LVA. Excluding all common causes for the LVA an idiopathic cause seemed most likely.
