Giant lateral left ventricular wall aneurysm sparing the submitral apparatus.
ABSTRACT: 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.
Project description:Annular submitral left ventricular aneurysm, which predominantly occurs in blacks who live in tropical regions of Africa, is a relatively unknown cardiac condition in the United States. We describe a patient with submitral left ventricular aneurysm who underwent resection of the mass and of the native mitral valve, followed by mitral valve replacement.
Project description:Submitral aneurysm is a rare entity, with around few hundred cases reported till date. Presentation can be varied. We describe here a case of submitral aneurysm in a young male with rupture into the left atrium cavity.
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.
Project description:Submitral aneurysm is a rare structural abnormality of congenital or acquired aetiology. Most reported cases are from Africa. Unless promptly treated surgically this condition is invariably fatal. We report a case of a young Indian male who presented with dyspnea of recent onset, diagnosed to have a massive submitral aneurysm causing low cardiac output and compression of cardiac structures.
Project description:A 28-week-old fetus was detected to have a single left atrial mass in prenatal ultrasound. Postnatal echocardiography showed an aneurysm between the anterior mitral leaflet and aortic valve, to the left of atrioventricular junction and communicating with the left ventricle through a narrow mouth. It probably originated from the mitral-aortic intervalvular fibrous tissue and an inherent weakness at this site might be the cause. Reported cases of pseudoaneurysm of mitral-aortic intervalvular fibrosa and subvalvular ventricular aneurysms seen following infective endocarditis, surgery, or trauma seem to have a similar anatomical background. This case explains the possibility of congenital aneurysm in this location which needs to be considered a differential diagnosis in similar cases.
Project description:We present echocardiographic images in two children with a diagnosis of submitral aneurysm. Both had absolutely different presentations. The diagnosis was established on echocardiography and no advanced imaging techniques were used.
Project description:Highlights•Idiopathic left ventricular aneurysm is a rare diagnosis.•Management and prognosis of idiopathic left ventricular aneurysms remain unknown.•We describe a conservative management of an idiopathic left ventricular aneurysm in a geriatric patient.
Project description:Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of the normal adjacent artery segments or the diameter of the patient's largest coronary artery by 1.5 times. The incidence of giant CAA is difficult to be determined, since only few reports have been described in the literature.A 65-year-old man was referred to our hospital because of a "mass" in the right heart detected on echocardiography at a regular medical health examination, while he experienced no any symptoms. Coronary angiography showed the severe stenosis of the left anterior descending artery (LAD) and the left circumflex artery (LCX) and the diffusely ectatic change of the right coronary artery (RCA), but no mass was found in any of these arteries. Coronary computed tomography angiography (CTA) confirmed that the "mass" was the giant aneurysms of RCA with thrombus. He received coronary artery bypass graft (CABG) with thrombectomy. The histopathology showed the deposits of lipid and hyalin in the tunica intima, the focal calcifications, the very thin tunica media, and the disappearance of the part of the tunica media in the RCA.Coronary artery aneurysm which may contain thrombus can complicate a diagnostic coronary angiography due to the risk of distal embolization and may lead to myocardial infarction. This case report demonstrates 2 RCA aneurysms with a thrombus presenting as a giant "mass" which was successfully treated by CABG with thrombectomy.
Project description:Mycotic cerebral aneurysms can present unique neurosurgical challenges. We report a patient with left carotid occlusions, a ruptured left middle cerebral artery mycotic aneurysm, and a rapidly appearing unruptured left anterior cerebral artery/anterior communicating artery (ACA/ACom) mycotic aneurysm in the setting of mitral valve endocarditis with a perivalvular leak and evolving congestive heart failure. Following medical stabilization and antibiotic administration, a combined endovascular (with contralateral access via the ACom) and open surgical approach was used to selectively secure both aneurysms with preservation of distal flow, allowing lifesaving cardiac valve replacement. This case illustrates the therapeutic complexity of mycotic cerebral aneurysms, which we discuss in the context of an increasing reliance on endovascular approaches.
