Abstract—Aortic stenosis is the most frequent valvular heart disease. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Surgical aortic valve replacement or transcatheter aortic valve implantation is the sole effective therapy in symptomatic patients with severe aortic stenosis, whereas the ma...
Aims: To examine how left atrioventricular plane displacement (AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. Methods and results: Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac diseases (mean (SD) age 6...
The bicuspid aortic valve is a common congenital cardiac anomaly, having an incidence in the general population of 0.9% to 2.0% and a frequency of 54% in all patients aged >15 years with valvular aortic stenosis. In most cases it remains undetected until infective endocarditis or calcification supervenes. The bicuspid aortic valve may function normally throughout life, may develop progressive c...
Aortic stenosis is a common disorder. Aortic valve replacement is indicated in symptomatic patients with severe aortic stenosis, as the prognosis of untreated patients is poor. Nevertheless, many patients pose a prohibitively high surgical risk and are not candidates for surgical valve replacement. Transcatheter aortic valve implantation (TAVI) is a novel method to treat selected high-risk pati...
AIM The standard tool to evaluate and follow up patients with aortic stenosis is Echocardiography. Nevertheless, most of the current echocardiographic parameters have limitations in predicting symptom onset and clinical outcome. Association of BNP with symptom onset in aortic stenosis although validated may be used as a hemodynamic marker to predict outcome in severe AS. Aim is to investigate t...
BACKGROUND We compared transcatheter aortic-valve replacement (TAVR), using a self-expanding transcatheter aortic-valve bioprosthesis, with surgical aortic-valve replacement in patients with severe aortic stenosis and an increased risk of death during surgery. METHODS We recruited patients with severe aortic stenosis who were at increased surgical risk as determined by the heart team at each ...
BACKGROUND Aortic-valve stenosis can be complicated by bleeding that is associated with acquired type 2A von Willebrand syndrome. However, the prevalence and cause of the hemostatic abnormality in aortic stenosis are unknown. METHODS We enrolled 50 consecutive patients with aortic stenosis, who completed a standardized screening questionnaire to detect a history of bleeding. Forty-two patient...
Percutaneous valve replacement for severe aortic stenosis has been shown to be an alternative treatment option for high surgical risk patients. We describe our first valve-in-valve procedure in a patient with a degenerated aortic bioprosthesis and severe regurgitation.
hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (avr).the mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. it appears to be independent of its severity as assessed by echocardiography. we present a case of a 24-year-old man with a histo...
