Transcatheter aortic valve implantation (TAVI) has emerged as a less invasive treatment than surgical aortic valve replacement in patients with aortic stenosis. Understanding the anatomy of aortic valve complex may help in optimal positioning of prosthetic valve and circumvent complications that can arise during its implantation.

The study aimed to characterize the geometry of the aortic root pre- and post-transcatheter aortic valve replacement (TAVR) and investigate differences in pre- and post-TAVR anatomy.
Degree of valve calcification in patients undergoing transfemoral transcatheter aortic valve implantation with and without balloon aortic valvuloplasty: Findings from the multicenter EASE-IT TF registry.
We aimed to assess whether the level of aortic root calcification is associated with BAV performance/omission during transcatheter aortic valve implantation (TAVI), and to explore related outcomes.
Transcatheter aortic valve replacement (TAVR) has become the cornerstone for aortic valve intervention since the first implantation in 2002. Recent advances with novel devices and introduction into lo...
The objective of this study was to determine whether valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) is associated with better survival than redo surgical aortic valve replacement...
Reconstructive surgery of the aortic valve is being increasingly used in patients with aortic regurgitation and/or aortic aneurysm. Its success depends on restoring normal aortic valve and root form. ...
Multicenter, prospective, observational study in aortic stenosis (AS) patients undergoing transcatheter aortic valve implantation (TAVI) or high-risk patients undergoing aortic valve repla...
The progress in surgery of the aortic root and the evolution of transcatheter aortic valve replacement as an alternative to surgical treatment in selected patients have refocused the need ...
The spreading of transcatheter aortic valve implantation has paradoxically increased the spectrum of indications for balloon aortic valvuloplasty. Balloon aortic valvuloplasty is currently...
A prospective, single arm clinical investigation evaluating safety and effectiveness/performance of the Microport CardioFlow VitaFlowTM II - Transcatheter Aortic Valve System for the treat...
Aortic valve disease is a progressive illness that varies from minor valve thickening lacking obstruction of blood stream to severe calcification and alteration of the valve leading to wea...
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.
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
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 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.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
