The Portico™ transcatheter aortic valve implantation (TAVI) system (Abbott Vascular, Santa Clara, CA, USA) was specifically designed to reduce some of the limitations associated with first-generation TAVI devices. Most of the currently available clinical evidence was obtained from randomized studies that compared TAVI to aortic valve replacement using first-generation transcatheter heart valve devices. The aim of this review is to describe the characteristics of the repositionable and retrievable Portico™ system and the technique of implantation, as well as to provide an overview of the most recent outcomes in the literature, along with our institutional experience.

To compare clinical and functional outcomes of regional and urban patients after transcatheter aortic valve implantation for severe aortic stenosis.
The aim of this study was to compare clinical outcomes of patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) with balloon-expandable (BE) valves vs. self-expandable (SE) v...
Multivalvular disease is of increasing concern in elderly patients undergoing transcatheter aortic valve replacement (TAVR). The objective of the present analysis was to investigate the impact of conc...
Transcatheter aortic valve replacement (TAVR) is a recent and an effective treatment option for high- or extreme-surgical-risk patients with symptomatic severe aortic stenosis. However, pure severe na...
Although aortic valve replacement (AVR) can be lifesaving, many patients with symptomatic aortic stenosis do not undergo appropriate therapy. This study sought to examine the characteristics, outcomes...
According to current European Recommendations on valvular heart disease (VHD), "classical" severe aortic stenosis (AS) is defined by an aortic valve area (AVA) ≤1 cm2 and indexed AVA ≤...
This study will evaluate hemodynamic and functional changes resulting from valve intervention in patients with severe aortic stenosis undergoing valve replacement (AVR) or transcatheter ao...
The purpose of this study is to determine that Transcatheter aortic valve replacement (TAVR) with SAPIEN 3 is superior to traditional surgical aortic valve replacement(SAVR) with bio-prost...
To evaluate the safety and performance of the HLT System in patients with severe aortic stenosis who present at high risk for aortic valve replacement surgery.
TAVI is still a relatively new technique that is emerging with advance in the percutaneous and implantable valve technology. Despite its safe use in inoperable and high risk patients with ...
Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.
A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
A pathological constriction occurring in the region above the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
