OBJECTIVE To determine the incidence and prognosis of congenital aortic valve stenosis in the five Health Districts of Liverpool that make up the Merseyside area. DESIGN The records of the Liverpool Congenital Malformations Registry and the Royal Liverpool Children's Hospital identified 239 patients (155 male, 84 female) born with aortic valve stenosis between 1960 and 1990. Patients were tra...

The severity of aortic stenosis is an important determinant of prognosis in patients with symptoms who do not undergo valve replacement. To assess the pitfalls of using valve gradients alone 636 patients with aortic stenosis in whom the aortic valve area had been calculated by the Gorlin formula were studied. The correlation between valve area and aortic gradients was poor. No gradient was foun...

BACKGROUND Intermittent stuck valve after mechanical valve replacement surgery is a very rare and severe complication. CASE SUMMARY We present 1 case of a 53-year-old woman after aortic valve replacement for severe aortic valve stenosis combined with hypertrophy septum. She was diagnosed with intermittent stuck valve only 1 day after surgery by clinical symptoms, intraoperative transoesophage...

Aortic valve stenosis resulting from calcific thickening of a previously normal 3-cusp aortic valve or a congenitally bicuspid aortic valve is a common clinical condition in developed countries, and its prevalence is continuing to increase with aging of the population.1,2 In the Cardiovascular Health Study, which involved 5201 men and women 65 years of age, the prevalence of aortic stenosis was...

T he introduction of balloon valvuloplasty for aortic stenosis first reported by Cribier and colleagues in 19861 was initially greeted with enthusiasm, especially by the interventional cardiologists who had in Samsonlike tradition2 crushed the pillars of atherosclerotic coronary arteries with balloon catheters and were now anxious to do the same to calcified aortic valve leaflets. The success o...

Two-dimensional and Doppler echocardiography was performed prospectively in 100 patients with aortic stenosis who were undergoing clinically indicated cardiac catheterization. The purpose of this study procedure was to determine various Doppler variables predictive of the severity of aortic stenosis and to compare Doppler- and catheterization-derived aortic valve areas. Doppler-derived mean gra...

Described herein are five patients who had double left-sided cardiac valve replacement for mitral and aortic valve stenosis resulting from two different etiologies: rheumatic heart disease, the cause of the mitral stenosis, and congenital heart disease (bicuspid valve), the underlying cause of the aortic stenosis.

OBJECTIVE In this study, we have designed an analog circuit model of the cardiovascular system that is able to simulate normal condition and cardiovascular diseases, such as mitral stenosis, aortic stenosis, and hypertension. Especially we focused on severe aortic stenosis, because it is one of the causes of sudden death in asymptomatic patients. In this study, we aim to investigate the simulat...

Transcatheter aortic valve implantation (TAVI) is currently reserved for high or prohibitive surgical-risk patients with aortic valve stenosis. We report on successful TAVI in two Jehovah's witness patients. It offers a simple and effective treatment of severe aortic valve stenosis in high-risk patients who refuse the use of allogeneic blood and blood products.

Transcatheter aortic valve implantation is increasingly being used to treat severe aortic stenosis in patients with high operative risk. In an aging population the incidence of aortic stenosis is rising, and increasing numbers of elderly patients are undergoing aortic valve replacement with bioprosthetic valves. Therefore, there is a corresponding increase in prosthetic degeneration. This prese...
