The impact of aortic valvular resistance (VR) on the degree of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR) remains unclear. The objective of the study was to investigate the relationship between VR and paravalvular AR after TAVR.

Radiofrequency ablation at the aortic root has the potential risk of aortic regurgitation (AR).
The objective of this study was to analyze the available literature on using transcatheter aortic valve replacement (TAVR) for native aortic regurgitation (AR).
Post/preprocedural ratio of hemodynamically assessed aortic regurgitation index as a marker for the need for corrective measures during transcatheter valve replacement: A first confirmatory study in patients receiving a new generation transcatheter self-expandable prosthesis.
We aimed to investigate the value of post/preprocedural aortic regurgitation index (ARI) ratio as a marker for more-than-mild aortic regurgitation (AR) after transcatheter aortic valve replacement (TA...
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...
Neo-aortic root dilatation and regurgitation are common progressive long-term complications of the arterial switch operation (ASO) for transposition of the great arteries (TGA) with increasing clinica...
The spreading of transcatheter aortic valve implantation has paradoxically increased the spectrum of indications for balloon aortic valvuloplasty. Balloon aortic valvuloplasty is currently...
The ASSESS-REGURGE is a multicenter, multicontinental registry on protocoled aortographic image acquisition after implantation of a transcatheter aortic valve. After the implementation of ...

This study is to evaluate the efficacy and safety of transcatheter aortic valve replacement (TAVR) in severe 'pure Aortic regurgitation (AR)' using Evolut R valve (Medtronic, Minneapolis, ...
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.
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Arthroplasty is a surgical procedure to restore the integrity and function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints. Osteo...
