Diagnosis and treatment of aortic valve stenosis
No full textAortic valve stenosis (AS) is the most frequently observed valvular heart disease. Once it is symptomatic the mortality rapidly increases. The diagnostic gold standard is transthoracic echocardiography. By measuring the maximum transvalvular velocity, mean transaortic pressure gradient and aortic valve opening area, classification of the type of stenosis can be defined. A differentiation is made between high-gradient AS, low-flow low gradient AS with reduced ventricular ejection fraction (<50%) and the paradoxical low-flow low-gradient AS with preserved ventricular function (≥50%). In some cases, additional diagnostic tools are necessary using dobutamine stress echocardiography, transesophageal echocardiography and cardiac computed tomography. The treatment follows an individualized approach. In cases of indications for valve replacement the multidisciplinary heart team takes into account the patient's age and individual risk for deciding whether an open surgical approach or transcatheter aortic valve implantation is indicated
