1/43. Unruptured congenital aneurysm of the sinus of valsalva presenting with pulmonary stenosis.Congenital aneurysm of the sinus of valsalva is a rare cardiovascular anomaly. It is usually silent until rupture occurs. The natural history of unruptured aneurysm of the sinus of valsalva is still not clear, and the therapeutic strategy is uncertain. Here we reported a case of unruptured aneurysm of the sinus of valsalva which was correctly diagnosed before invasive diagnostic procedures. A 30-year-old female noted mild palpitation and dyspnea for 1 month. Physically, a grade 3/6 systolic ejection murmur at upper left sternal border was detected. echocardiography revealed dilatation and irregular protrusion of the right sinus of valsalva encroaching on right ventricular outflow tract to cause obstruction. With these findings, unruptured aneurysm of the sinus of valsalva with pulmonary stenosis was diagnosed. cardiac catheterization and angiography confirmed the diagnosis. The aneurysm was repaired with a Dacron patch with good results. It is concluded that sinus of valsalva aneurysm can be diagnosed by echocardiography before its rupture so as to render a proper management for this potentially life-threatening anomaly.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/43. Obstruction of the right ventricular outflow tract caused by a tuberculoma in a patient with ventricular septal defect and aneurysm of the membranous septum.Reported here is an obstruction of the right ventricular outflow tract caused by a tuberculoma in a 15-year-old boy who presented with a ventricular septal defect. The obstruction was discovered at surgery and the tuberculous aetiology was only demonstrated histologically. To the authors' knowledge, this is the first report of a tuberculoma of the heart associated with congenital heart disease.- - - - - - - - - - ranking = 0.4keywords = aneurysm (Clic here for more details about this article) |
3/43. Pseudoaneurysm in the mitral-aortic intervalvular fibrosa. A cause of mitral regurgitation.Left ventricular outflow tract pseudoaneurysm is an uncommon but potentially catastrophic complication of aortic valve surgery, aortic valve endocarditis or chest trauma. We describe a case of a left ventricular outflow tract pseudoaneurysm 1 month after an aortic valve replacement that caused a systolic compression of mitral valve and a severe regurgitation. The diagnosis was confirmed using transoesophageal echocardiography, magnetic resonance image and intraoperative endoscopy. Surgical repair of the pseudoaneurysm corrected the mitral regurgitation.- - - - - - - - - - ranking = 1.2592469251236keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
4/43. Apical aneurysm and left ventricular hypertrophy.A 59-year-old woman presented with an embolic transient ischemic attack and a history of controlled hypertension for 16 years. Both echocardiogram and MRI showed severe biventricular hypertrophy and an apical aneurysm with a thrombus. The occurrence of an apical aneurysm in the presence of cardiac hypertrophy is a rare finding and has been described in patients with hypertrophic cardiomyopathy. However, it has not been reported in patients with systemic arterial hypertension. In this patient the lack of a relationship between the severity of the hypertrophy and the levels of blood pressure, together with the presence of histologic disorganization of myocardial cardiac muscle cells by endomyocardial biopsy suggested the diagnosis of hypertrophic cardiomyopathy.- - - - - - - - - - ranking = 0.6keywords = aneurysm (Clic here for more details about this article) |
5/43. Sinoatrial nodal artery aneurysm with right ventricular outflow tract compression: report of a case.We described a 16-year-old boy with sinoatrial nodal (SAN) artery aneurysm that drained into right atrium and compressed right ventricular outflow tract. The patient was clinically asymptomatic. Hemodynamic study revealed a 15 mm Hg peak systolic pressure gradient at right ventricular outflow tract. The fistula was successfully excised without sequalae. Cathet. Cardiovasc.

6/43. Aneurysmal pericardial patch producing right ventricular inflow obstruction.A 2-month-old infant presented with acute onset of heart failure, having previously undergone anatomical repair of transposition of the great arteries and ventricular septal defect (VSD). echocardiography demonstrated aneurysmal dilation of the native pericardial patch used for VSD closure, resulting in right ventricular inflow obstruction. The pericardial patch was excised, and the VSD closed using a GoreTex patch.- - - - - - - - - - ranking = 0.1keywords = aneurysm (Clic here for more details about this article) |
7/43. Hypertrophic cardiomyopathy with midventricular obstruction and apical aneurysm: a case report.A 71-year-old woman had hypertrophic cardiomyopathy associated with midventricular obstruction and an apical aneurysm in the left ventricle. She had had abnormal electrocardiograms for more than 30 years and for the past year had been suffering from occasional attacks of dizziness and low systemic blood pressure. Holter 24-h electrocardiographic monitoring revealed ventricular paroxysmal contractions (676/day) with nonsustained ventricular tachycardia. Doppler echocardiography revealed paradoxical jet flow from the apical aneurysm to the left ventricular outflow during early diastole. magnetic resonance imaging depicted midventricular hypertrophy and a dyskinetic thin apical wall, which were confirmed by angiography. Coronary angiograms showed no narrowing of the major extramural coronary arteries, but there was compression of aberrant coronary arteries apparently feeding the hypertrophic portion of the left ventricular wall. Stress thallium-201 myocardial imaging showed a persistent severe defect in the left ventricular apex. A hemodynamic study revealed low cardiac output and an intraventricular pressure gradient (approximately 90 mmHg) between the left ventricular apical high-pressure chamber and the subaortic low-pressure chamber. The present case represents a rare combination of hypertrophic cardiomyopathy, midventricular obstruction, and an apical aneurysm in an elderly woman. myocardial ischemia may have played an important role in the genesis of the apical aneurysm.- - - - - - - - - - ranking = 0.8keywords = aneurysm (Clic here for more details about this article) |
8/43. Pseudoaneurysm of the right ventricular outflow tract complicating balloon dilatation for tetralogy of fallot.Balloon dilatation is one of the treatment options in symptomatic infants with tetralogy of fallot and hypoplastic pulmonary annulus and pulmonary artery. A balloon dilatation was performed on a 28-day-old infant with tetralogy of fallot with an appropriate balloon. The patient developed two pseudoaneurysms on the right ventricular outflow tract after the procedure which were diagnosed when the patient was admitted for total correction at 20 months of age. This case demonstrates an unusual but potentially life-threatening long-term complication of this procedure.- - - - - - - - - - ranking = 0.68641564170785keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/43. Right heart obstruction from a balloon-like sinus of valsalva aneurysm in a patient with down syndrome.A 40-year-old man with down syndrome presented with right heart failure. He was markedly obese and had severe developmental delay. There was marked edema and an early diastolic sound. Transthoracic echocardiography suggested a right heart mass. Transesophageal echocardiography revealed an unruptured balloon-like sinus of Valsalva aneurysm within the right atrium that obstructed the tricuspid orifice. The patient died in hospital of mixed obstructive and/or septic shock.- - - - - - - - - - ranking = 0.5keywords = aneurysm (Clic here for more details about this article) |
10/43. Left main coronary artery compression by dilated main pulmonary artery in endocardial cushion defect.A 56-year-old man was evaluated for exertional dyspnoea. Chest X-ray showed mild cardiomegaly and a dilated main pulmonary artery. On echocardiogram he was found to have ostium primum atrial septal defect with moderate tricuspid insufficiency. cardiac catheterization revealed an oximetry step-up of 14% at low right atrium with angiogram demonstrating a cleft in the mitral valve, an elongated left ventricular outflow tract and ventricular septal defect closed by a septal aneurysm. Coronary angiogram revealed ostial compression of the left main coronary artery with the rest of the coronary artery anatomy being normal.- - - - - - - - - - ranking = 0.1keywords = aneurysm (Clic here for more details about this article) |
