1/58. An unusual combination of cardiovascular surgical disorders.A 53-year-year-old man presented with aortic regurgitation, subvalvular and supravalvular aortic stenoses, and aneurysms involving the ascending aorta, the arch, and the innominate, right subclavian, and left common carotid arteries. Surgery consisted of resection of the obstructive lesions, replacement of the aortic valve, graft replacement of the ascending aorta, and the arch resection of innominate and subclavian artery aneurysms and reconstruction with a side limb to which the right carotid artery was anastomosed. The patient has remained asymptomatic with full employment.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/58. Recurrent endocarditis in silver-coated heart valve prosthesis.BACKGROUND AND AIM OF THE STUDY: In order to prevent prosthetic valve endocarditis (PVE), the implantation of a new silver-coated sewing ring has been introduced to provide peri- and postoperative protection against microbial infection. methods: A 56-year-old woman with aortic stenosis had elective replacement with a St. Jude Medical mechanical valve fitted with a silver-coated sewing ring (Silzone). The patient developed early PVE, which necessitated reoperation after one month. Despite a second Silzone prosthesis being implanted, the endocarditis recurred. During a third operation an aortic homograft was implanted, and after six months a fourth operation was performed for a pseudoaneurysm at the base of the homograft, in proximity to the anterior mitral valve leaflet. RESULTS: The diagnosis of PVE was confirmed by the presence of continuous fever, transesophageal echocardiography and growth of penicillin-resistant staphylococcus epidermidis from the valve prosthesis. CONCLUSION: The implantation of all prosthetic valves is encumbered with a risk of endocarditis. Although silver has bacteriostatic actions, the advantages of silver-coated prostheses in the treatment of this condition have yet to be assessed in clinical trials.- - - - - - - - - - ranking = 1.1411473961507keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/58. Ultrasound guided percutaneous thrombin injection for the treatment of iatrogenic pseudoaneurysms.Iatrogenic aneurysms are usually postcatheterisation pseudoaneurysms of the femoral artery. Until recently, the treatment of choice was ultrasound guided compression repair. A case of pseudoaneurysm of the axillary artery, arising as a complication of pacemaker insertion in an 83 year old man is reported. Compression repair was not possible in this case, and so the aneurysm was occluded by percutaneous ultrasound guided thrombin injection directly into the aneurysm sac. Percutaneous ultrasound guided thrombin injection is a promising new minimally invasive technique for the treatment of iatrogenic pseudoaneurysms.- - - - - - - - - - ranking = 9.4880317730551keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/58. Pulmonary stenosis caused by extrinsic compression of an aortic pseudoaneurysm of a composite aortic graft.Pulmonic stenosis and stenosis of the right ventricular outflow tract related to extrinsic compression have been described in patients with tumors, in a patient with a pericardial cyst, and in patients with vascular abnormalities as an unruptured sinus of valsalva aneurysm, a giant coronary artery pseudoaneurysm and an aortic arch aneurysm. Composite graft replacement of the ascending aorta and aortic valve with reimplantation of the coronary arteries has some inherent complications. Our case report describes a patient with a pericomposite graft aneurysm presenting as a stenosis of the pulmonary artery, detected by Doppler echocardiography.- - - - - - - - - - ranking = 7.2057369807536keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
5/58. Congenital aneurysm of the left ventricle associated with supravalvular aortic stenosis and aneurysm of the left main coronary artery: case report and review of the literature.We report a unique case of a 33 year old female with congenital aneurysm of the left ventricular apex associated with an aneurysm of the left main coronary artery and surgically repaired supravalvular aortic stenosis. The congenital aneurysm of the left ventricular apex was not associated with a midline thoraco-abdominal defect, as reported in the medical literature. The patient survived two episodes of thrombo-embolism and is well after 10 years of medical follow-up.- - - - - - - - - - ranking = 5.5keywords = aneurysm (Clic here for more details about this article) |
6/58. Left ventricular septal aneurysm in association with bicuspid aortic valve--a case report.Diverticula of the left ventricle are rare cardiac anomalies. Most cases arise from the apex of the left ventricle and are usually found in children. Only a few cases have been documented in adults. The authors report a case of a 38-year-old woman who presented with dyspnea and chest pain. She was found to have a septal left ventricular diverticulum associated with bicuspid aortic valve, aortic stenosis, and aortic regurgitation. The aortic valve was replaced with the resection of the diverticulum. Pathologic examination confirmed the diagnosis of fibrous diverticulum.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
7/58. Interventional and surgical management of aortic stenosis and coarctation.Two patients, aged 42 and 44 years old, presented with the combination of aortic valve stenosis and coarctation. To avoid potential problems associated with one stage repair, both patients underwent successful endovascular stent implantation for coarctation followed within 2 weeks by aortic valve replacement using pulmonary autografts (Ross operation). Spiral thoracic computed tomographic scans were performed within 1 week of stent implantation to ensure the absence of aneurysm formation related to the stent before cardiopulmonary bypass.- - - - - - - - - - ranking = 0.5keywords = aneurysm (Clic here for more details about this article) |
8/58. bicuspid aortic valve stenosis complicated by descending aortic dissection mimicking coarctation of the aorta.We report a rare case of bicuspid aortic stenosis complicated by an ascending aortic aneurysm and aortic dissection of DeBakey type IIIb. A 35-year-old woman was admitted to our hospital to examine her systolic murmur identified at birth. Severe aortic stenosis, dilatation of the ascending aorta, and the narrow color flow signal in the descending aorta were detected by transthoracic echocardiography. Initially, coarctation of the descending aorta was suspected, but aortic dissection, DeBakey type IIIb, was revealed by transesophageal echocardiography. Transesophageal echocardiography is indicated when only insufficient information is available on valve and aortic morphology in patients with bicuspid aortic valve.- - - - - - - - - - ranking = 0.5keywords = aneurysm (Clic here for more details about this article) |
9/58. Endoventricular circular patch plasty with aortic valve replacement for post-infarction cardiac rupture complicated with aortic valve stenosis: case report.Cardiac rupture after acute myocardial infarction (AMI) in patients with aortic valve stenosis (AS) is uncommon and only 2 survival cases after surgery have been reported to date. The present patient, a 69-year-old woman with aortic valve stenosis (AS), suffered an acute myocardial infarction and despite a successful baloon angioplasty to the proximal left anterior descending artery, the condition progressed into congestive heart failure. echocardiography demonstrated AS with a valve area of 0.7 cm2 and a left ventricular aneurysm with a thin and dyskinetic anterior to apical wall. An urgent operation was performed and the opening of the pericardium revealed oozing rupture of the aneurysm. An endoventricular circular patch plasty combined with aortic valve replacement was successfully performed, and good results during 2-year follow-up were achieved. Physiological repair with exclusion of the infarcted area is essential to achieve a good long-term outcome in such a critical case. Special care should be taken with AMI in a patient with AS because of the possible occurrence of aneurysm and rupture of the left ventricle.- - - - - - - - - - ranking = 1.5keywords = aneurysm (Clic here for more details about this article) |
10/58. Dissecting aneurysm of aorta complicating aortic valvular stenosis.Six cases of classical dissecting aneurysm of the aorta complicating aortic valvular disease in which aortic stenosis was dominant are described. In three of the cases the aortic complication occurred after the natural aortic valve had been replaced by a prosthetic valve. The longest postoperative period was four months. The factor common to all reported cases in our series was cystic medial necrosis of the aorta. The authors agree with the concept of McKusick and associates that aortic dissecting aneurysm complicating aortic valvular disease is an association other than chance and is related to cystic medial necrosis of the aorta. The latter, in turn, is a consequence of the altered hemodynamics of aortic valvular disease, particularly stenosis.- - - - - - - - - - ranking = 3keywords = aneurysm (Clic here for more details about this article) |
