The authors analyzed long-term recurrent aortic regurgitation (AR) in 249 patients with aortic insufficiency and reimplantation procedure. Of the cusp repair techniques evaluated in the analysis, only free margin reinforcement and patch repair influenced valve durability, the former positively and the latter negatively.

Aortic valve disease
June 19, 2017
Gaudino and colleagues report a retrospective analysis of short-term outcomes following aortic valve-sparing operations (VSO) with and without reconstruction of the sinuses of Valsalva (SV). Despite the importance of the SV for aortic valve function, data evaluating SV reconstruction with VSO are limited.

In this video, the authors demonstrate the feasibility of performing a complex aortic valve repair for aortic valve endocarditis via an upper partial sternotomy.

A statewide quality initiative database that included over 11,500 pts undergoing surgical AVR (SAVR) who were assessed for outcomes based on pre-TAVR and post-TAVR time periods (divided into early TAVR and commercial TAVR). SAVR rates increased with each time period, wheres predicted mortality rates decreased, observed mortality was lowest during th

Data from the Centers for Medicare and Medicaid Services related to patients aged 65 and older who underwent TAVR during a 2 year period were evaluated, stratified into older (age 90 or greater; 19.3%) and younger cohorts. Nonagenarians had fewer comorbidities. Mortality was higher in nonagenarians (8.4% vs 5.9%) as was morbidity (25.4% vs 21.5%).

This video shows the treatment of a 5-year-old patient with a rapidly enlarging aneurysm and left ventricular outflow tract to pulmonary artery shunt.
One-Year Outcomes of Transcatheter Aortic Valve Replacement in Patients With End-Stage Renal Disease
May 17, 2017
Using data from the CoreValve US Expanding Use Study, outcomes for patients with end stage renal disease (ESRD) undergoing TAVR were evaluated using an endpoint of all-cause mortality or major stoke at 1 year. Mortality at 1 year was 30%, and the stroke incidence was 2.1%. New permanent pacemaker need was 27%.

Bicuspid aortic valve (BAV) has been considered a relative contraindication for transcatheter aortic valve implantation (TAVI). Nevertheless, favourable results have been reported from registries and observational reports.

This video demonstrates a "hemi-commando" procedure in a 64-year-old female patient with aortic root abscess involving the intervalvular fibrosa.

Using MR scans and computational fluid dynamics, the authors sought to evaluate differences in flow, shear stress, and oscillatory shear stress in normal individuals and patients with 1 of 4 different categories of aortic valvular disease. The flow patterns were patient and category specific, and may provide the ability to determine interventions on
