RATIONALE Doppler echocardiography has been demonstrated to be accurate in diagnosing valvular lesions in rheumatic heart disease (RHD) when compared to clinical evaluation alone. OBJECTIVE To perform Doppler echocardiography in children clinically diagnosed by the Jones criteria to have acute rheumatic fever (ARF), and to then compare the effectiveness of echo in detecting single/multi-valvu...
In 43 patients left ventricular micromanometry and cineangiography were performed preoperatively and and 20 months after aortic valve replacement. A score of left ventricular functional impairment, derived from 5 to 8 haemodynamic variables, was calculated as: number of pathological indices x 100/total number of determined indices. Preoperatively the score of left ventricular functional impairm...
(2) Is the risk of proximal dissection high enough to warrant prophylactic repair before clinically significant aortic insufficiency occurs? (3) If surgery is not warranted now, what indication should be used to determine appropriate timing of surgery (ie, aortic regurgitation by clinical examination, symptomatic aortic regurgitation, signs of congestive heart failure)? (4) How common is a type...
OBJECTIVE We studied the mechanistic links between fibrocalcific changes in the aortic valve and aortic valve function in mice homozygous for a hypomorphic epidermal growth factor receptor mutation (Wave mice). We also studied myocardial responses to aortic valve dysfunction in Wave mice. APPROACH AND RESULTS At 1.5 months of age, before development of valve fibrosis and calcification, aortic...
1 of 2 DESCRIPTION Rupture of mitral-aortic intervalvular fi brosa aneurysm is a rare complication of aortic valve endocarditis. 1 A 43-yearold man presented with persistent fever and progressive dyspnoea of 3 months duration. On admission, he was in fl orid pulmonary oedema and clinical examination showed fi ndings of severe aortic regurgitation. His electrocardiogram revealed complete heart b...
ABSTRACT: Acute rheumatic fever and rheumatic heart disease are the common health problems of developing countries.Prevention and Control of Rheumatic heart disease is an important task of cardiovascular health program under World Health organisation. During 3 years 422,000 School children in four areas of Guilan province were screened (371400 urban and 50600 rural area children ). 166 cases ...
OBJECTIVES This analysis reports on the initial German multicenter experience with the JenaValve (JenaValve Technology GmbH, Munich, Germany) transcatheter heart valve for the treatment of pure aortic regurgitation. BACKGROUND Experience with transcatheter aortic valve implantation (TAVI) for severe aortic regurgitation is limited due to the risk of insufficient anchoring of the valve stent w...
The aortic root of a 30-year-old man was replaced with a Freestyle stentless aortic bioprosthesis for aortic regurgitation associated with annuloaortic ectasia. His clinical course was uneventful, and he was discharged without complications. Three years and six months after surgery, he presented with a high fever. Four years after surgery, transthoracic echocardiography revealed severe aortic r...
The outcome in functional mitral regurgitation after aortic valve replacement is unclear. A frail 82-year-old woman with severe aortic valve regurgitation and mild to moderate functional mitral valve regurgitation (NYHA functional class III) was referred to our clinic. In consideration of her frail condition, aortic valve replacement without mitral surgery was performed. She had hemodynamic ins...
Takayasu arteritis is a chronic inflammatory disease of unknown etiology primarily affecting the aorta and its major branches and usually occurring in the second or third decade of life. Here, we report a case of Takayasu arteritis in a 10-month-old patient. The infant presented with signs of congestive heart failure and severe aortic regurgitation. Echocardiography and computed tomography angi...
