A previously healthy 18-year-old female presented for evaluation of a 3-month history of fatigue. Other notable findings in the history were progressively worsening dyspnea on exertion, 3-pillow orthopnea, a newly developed cough, and a 20-lb weight loss. The physical examination demonstrated tachypnea, with a respiratory rate of 24 breaths per minute, and the lungs were clear. The heart rate w...
that occurs almost exclusively in young children with or without various forms of congenital heart disease (1). Pulmonary vein stenosis in the adults is very rare, and the small number of reported cases has often been associated with mediastinal processes such as neoplasms or fibrosing mediastinitis (2, 3). Recently, stenosis has appeared as a complication of radiofrequency ablation procedures ...
cutis laxa (cl) is a rare congenital and acquired disorder characterized by loose and redundant skin with reduced elasticity. three types of congenital cutis laxa have been recognized. other findings are pulmonary emphysema, bronchiectasia, hernia and diverticulosis. we describe a female neonate involved by cutis laxa syndrome and a positive family history. we focus on the radiologic findings o...
BACKGROUND Cor triatriatum is a rare congenital cardiac abnormality, consisting of an obstructing membrane between the pulmonary veins and the mitral valve in varying patterns. The entitiy can mimick the pathophysiology of mitral stenosis, necessitating surgical resection. Occasionally, percutaneous balloon dilatation of the membrane has been successfully performed. CASE PRESENTATION We repor...
Patients with rheumatic mitral stenosis often have no pulmonary oedema despite considerably increased pulmonary venous pressure. Pulmonary microvascular permeability was measured non-invasively by a previously validated method of double isotope scintigraphy with indium-113m and technetium-99m. This permits calculation of an index reflecting transferrin efflux and thus, indirectly, the microvasc...
Pulmonary hypertension frequently complicates mitral stenosis. Increased pulmonary artery pressure results from raised left atrial pressure, pulmonary arteriolar constriction, and obliterative changes in the pulmonary vascular bed, and usually responds to surgical relief of mitral stenosis. However, severe pulmonary hypertension may persist after surgical treatment of mitral stenosis. We descri...
Five neonates with congenital tricuspid incompetence due to severe tethering of the tricuspid valve to the right ventricle by abnormal chordal and papillary muscle attachments are described. The abnormality was called tricuspid valvular dysplasia (TVD) if the basal insertion of the valve was normal and the Ebstein malformation if it was displaced into the sinus portion of the ventricle. In the ...
OBSTRUCTION to the outflow of blood from the right ventricle may occur as a result of congenital stenosis of the pulmonary valve, of the infundibulum, or of the supravalvular area. These all result in a fixed constriction of the lumen of the involved region. Recently, considerable interest has been focused upon a more dynamic type of infundibular obstruction that occurs in a number of patients ...
Congenital aortic valve anomalies are quite a rare finding in echocardiographic examinations. A case of a 19 year old man with a pentacuspid aortic valve without aortic stenosis and regurgitation, detected by transoesophageal echocardiography, is presented.
