A 56-year-old female with congestive heart failure was transferred to our institution. Aortography demonstrated aortic valve stenosis (AS) with a congenitally bicuspid valve and dilatation of the ascending aorta. Preoperative coronary angiography showed a left single coronary artery. Replacement of the aortic valve and ascending aorta was performed. She had an uneventful postoperative course. W...

There is a frequent association between aortic valve stenosis and gastrointestinal bleeding, also known as Heyde's syndrome. In these patients, the aortic valve replacement should be recommended as "gold standard." In high-surgical-risk patients, the Transcatheter Aortic Valve Implantation (TAVI) is an alternative option. However, the risk of bleeding recurrence, related to double antiplatelet ...

quadricuspid aortic valve (qav) is an uncommon congenital anomaly which was an incidental finding during surgery or autopsy in the past. we present the case of a 44-year-old woman with moderately severe aortic regurgitation due to unequal cusp size qav diagnosed via transesophageal echocardiography. due to echocardiographic imaging improvement, the diagnosis of qav is now easier and earlier tha...

Many patients with severe aortic stenosis never undergo surgical treatment for various reasons. Apart from the standard risks, some patients face an additional problem: their carrying of a mechanical mitral valve. In these patients, transcatheter aortic valve implantation is a therapeutic option. The literature contains only few reports of this procedure being performed (usually transapically) ...

The density of aortic valve calcification was estimated using cinefluoroscopy and M mode echocardiography in 86 patients with pure aortic stenosis. The results were compared with the degree of outflow obstruction measured haemodynamically. Cinefluoroscopic estimates of aortic valve calcification correlated well with the measured aortic valve gradient whereas echocardiographic results were less ...

BACKGROUND 3D stereolithographic printing can be used to convert high-resolution computed tomography images into life-size physical models. We sought to apply 3D printing technologies to develop patient-specific models of the anatomic and functional characteristics of severe aortic valve stenosis. METHODS AND RESULTS Eight patient-specific models of severe aortic stenosis (6 tricuspid and 2 b...

Most surgical heart valves currently implanted are bioprosthetic tissue valves. Such valves deteriorate with time, eventually presenting with either stenosis or regurgitation. Reoperation, the current standard of care for failed valves, carries significant risk in terms of both morbidity and mortality. Implantation of a transcatheter valve inside a failed surgical valve (valve-in-valve procedur...

BACKGROUND: Bicuspid aortic valve (BAV) is one of the most common congenital heart defects with a population prevalence of 0.5% to 1.3%. Identifying patients with BAV is clinically relevant because BAV is associated with aortic stenosis, endocarditis and ascending aorta pathology. METHODS AND RESULTS: Patients with severe aortic stenosis necessitating aortic valve replacement surgery were inclu...

alcific aortic valve disease is the most common acquired alvular disorder in developed countries. Disease involveent of the trileaflet aortic valve spans the spectrum from aortic sclerosis,” characterized by valve thickening, fibrosis, nd microscopic calcification without left ventricular outow obstruction, to frank “aortic stenosis,” characterized by ore severe involvement with limitation of v...

Infants with severe aortic valve stenosis often are critically ill and require urgent surgical treatment. Currently, angiography is used at the time of cardiac catheterization to diagnose aortic valve stenosis. However, the use of this test may be hazardous in an unstable infant and may precipitate hemodynamic and clinical deterioration before surgery. Therefore, a noninvasive method of accurat...
