Pathology of the Aortic Valve: Aortic Valve Stenosis/Aortic Regurgitation
Current Cardiology Reports, 2019This discussion is intended to review the anatomy and pathology of the aortic valve and aortic root region, and to provide a basis for the understanding of and treatment of the important life-threatening diseases that affect the aortic valve.The most exciting recent finding is that less invasive methods are being developed to treat diseases of the ...

Aortic valve stenosis is the most frequent reason for prosthetic valve replacement in adults. Its incidence increases with age. Development of the most frequent form, degenerative-calcific aortic stenosis, is related to atherosclerotic risk factors. The narrowing of the aortic valve orifice leads to creation of a systolic pressure drop, the gradient ...

Aortic Valve Replacement for Aortic Stenosis in Nonagenarians
The American Journal of Cardiology, 2006We reviewed certain clinical and morphologic findings in 9 patients who had aortic valve replacement (AVR) for aortic stenosis (AS) when >or=90 years of age. All had AVR from February 2000 to April 2006. The aortic valve areas ranged from 0.41 to 1.00 cm2, and the transvalvular peak systolic gradients ranged from 20 to 110 mm Hg.

Indications for Aortic Valve Replacement in Aortic Stenosis
Journal of Intensive Care Medicine, 2007Aortic stenosis is a common condition, particularly in the elderly. The treatment is surgical, and any patient with symptomatic severe aortic stenosis should be considered for aortic valve replacement. Aortic stenosis causes an increase in afterload to the left ventricle, which when severe can lead to hemodynamic instability.

Translocation of aortic valve for calcific aortic stenosis
The Japanese Journal of Thoracic and Cardiovascular Surgery, 2000A 56-year-old man underwent surgery for treatment of severe calcific aortic stenosis. Because it was found after excision of the aortic valve that calcification of the annulus was too extensive for the placement of sutures, translocation of the aortic valve was performed.

Transcatheter aortic valve replacement in bicuspid aortic valve stenosis
Progress in Cardiovascular Diseases, 2020Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality in adults, and symptoms typically develops in adulthood. In the majority of cases, BAV disease progresses with age and surgical aortic valve replacement (AVR) is performed with excellent operative outcomes.

Transcatheter aortic valve implantation in bicuspid aortic valve stenosis
EuroIntervention, 2016Bicuspid aortic stenosis (AS) is not rare in patients treated with transcatheter aortic valve implantation (TAVI). Bicuspid valves have unique anatomy which could affect the results of TAVI; however, multiple recent reports have shown that TAVI is safe and effective in this population.

Histopathology of calcific aortic valve stenosis
Acta Cardiologica, 2006Calcific aortic valve stenosis is the most common and increasing heart valve disease in the western world. In the last 30 years, diagnosis and management were revolutionized by the development of cardiac catheterisation, echocardiography, cardiac surgery, and medication.

Transcatheter aortic valve replacement in unicuspid aortic valve stenosis
Catheterization and Cardiovascular Interventions, 2016Unicuspid aortic valve (UAV) offers unique challenges to transcatheter aortic valve replacement (TAVR), due to asymmetric expansion and apposition of the prosthesis during implantation. Although TAVR in bicuspid is now a well described experience, TAVR in unicuspid valve has not yet been described. A challenging case is described with TAVR in UAV using

Transcatheter aortic valve implantation for bicuspid aortic valve stenosis
Catheterization and Cardiovascular Interventions, 2015Key Points In Preprocedural CT, patients with BAV have larger aortic annulus perimeters, and more calcified valves compared with TAV. In patients with BAV, self‐expandable valves were under‐expand and balloon‐expandable valves have a trend toward increased rates of postimplantation AR grade.
