Prosthetic aortic valve and conduit dehiscence with periconduit cavity and ascending aortic aneurysm is an uncommon complication of aortic root surgery. It is usually recognizable at echocardiography due to an abnormal position of the prosthetic valve and conduit in relation to the native aortic annulus in conjunction with an abnormal echolucent periconduit space that fills with color flow. Mit...

Aortic stenosis has been shown to share the same risk factors as atherosclerosis which suggested a potential benefit from statins therapy. Fourteen studies which provided the effect of statins treatment on aortic stenosis (AS) were meta-analyzed, including 5 randomized controlled trials (RCTs) and 9 observational studies. In the RCTs, statins did not have any influence on peak aortic valve velo...

Methods 46 patients with severe AS without obstructive coronary artery disease awaiting aortic valve replacement were studied. Transthoracic echocardiography (TTE) was used to assess aortic valve area using the continuity equation, peak aortic velocity and mean valve gradient. CMR was used to assess aortic valve morphology and to enable planimetry of aortic valve area. Two SSFP cines of the aor...

Aortic valve calcification is the most common form of valvular heart disease, but the mechanisms of calcific aortic valve disease (CAVD) are unknown. NOTCH1 mutations are associated with aortic valve malformations and adult-onset calcification in families with inherited disease. The Notch signaling pathway is critical for multiple cell differentiation processes, but its role in the development ...

OBJECTIVES This study sought to report on the feasibility and early results of transcatheter aortic valve implantation employing a second-generation device in a series of patients with pure aortic regurgitation. BACKGROUND Efficacy and safety of transcatheter aortic valve implantation in patients with calcific aortic stenosis and high surgical risk has been demonstrated. However, experience w...

Aortic valve replacement (AVR) has been the default procedure for the surgical management of aortic valve disease, with repair techniques heterogeneously and infrequently used. However, surgical aortic valve repair has evolved with improved techniques. Yet many questions remain regarding the ideal techniques and real-world applicability and effectiveness of valve repair. The AORTA Great Debate ...

Transcatheter aortic valves have been designed to treat elderly patients considered high-risk surgical candidates. Transcatheter aortic valve embolization represents a new complication previously unreported in the surgical bioprosthetic valve literature. We report the case of a 79-year-old male who successfully underwent aortic valve replacement after transcatheter aortic valve dislodgment into...
