Special Issue Introduction

Aortic stenosis (AS) is one of the most common heart valve diseases in developed countries. The surgical intervention has been the most common treatment widely used in this disease. Without proper treatment, the surgery will carry a serious dismal prognosis. Due to the advanced age or presence of severe comorbidities, many patients are not suitable for surgical aortic valve replacement. In this case, transcatheter aortic valve replacement (TAVR) has shown to be also effective for patients at intermediate and high risk.

Since its advent in 2002, the outcome has improved progressively. This is due to the patients' optimal selection, the increasing operators' expertise, better equipment both in terms of valve and delivery system technologies, as well as the preprocedural imaging evolution which plays an eminent role in the progress. Moreover, determining an accurate estimate of the aortic valve, ascending aorta, left ventricular outflow tract and peripheral vasculature is an fundamental element in determining the outcomes in patients undergoing TAVR. Therefore, procedure planning with the aid of adequate imaging techniques is vitally important to patients. Alongside 2-dimensional echocardiography, multislice computed tomography and other imaging techniques have shown to be able to provide useful and complementary information in the preprocedural TAVR planning. Many studies focused on anatomical features, comorbidities and procedural techniques that could lead to higher risk of paravalvular regurgitation, patient-prosthesis-mismatch, valve displacement with eventual need for second valve implantation, and conduction disturbances leading to the necessity of permanent pacemaker implantation.

This special issue focuses on the current research result of imaging and implantation technique in the periprocedural and long-term outcome of patients undergoing TAVR, and analyzes the rapid expansion of this procedure to younger and lower-risk patients, as well as the anatomical and procedural features which may lead to suboptimal outcome.
