Bicuspid Aortic Valve-Associated Ascending Thoracic Aortic Aneurysm: Patient-Specific Finite Element Analysis.

CONCLUSIONS: To the present authors' knowledge, this was the first patient-specific BAV aTAA model based on surgical specimens to be developed. Surgical specimens serve as the 'gold standard' for determining wall stress to validate models based on in-vivo imaging data alone. Regions of maximal wall stress may indicate sites most prone to rupture, and are crucial for evaluating rupture risk based on the wall stress/strength relationship. PMID: 27997777 [PubMed]

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

Bentall’s Procedure in Pediatric Mixed Connective Tissue Disease Syndrome: Management of Pediatric Aortic Aneurysm - A Brief Review. J Heart Valve Dis. 2017 Sep;26(5):610-612 Authors: Ramaprabhu K, Prakash O, Davidson N, Bhalero S, Radhakrishnan S, Coelho R Abstract Mixed connective tissue disease (MCTD) syndrome in children may lead to large aortic aneurysms, which in turn pose a difficult surgical problem. Valve-sparing root replacement is not always a viable option as the disease process invariably affects the aortic valve leaflets. Among pediatric patients, the Ross procedure is contraindicated on...

Medtronic (NYSE:MDT) said today it launched a pivotal trial of its Intrepid transcatheter mitral valve replacement system after winning FDA investigational device exemption for the device. The 1st patient in the trial was enrolled at Milwaukee’s Aurora St. Luke’s Medical Center, the Fridley, Minn.-based company said. The Apollo trial is slated to enroll up to 1,200 patients with severe, symptomatic mitral valve regurgitation into 2 cohorts with a primary endpoint of composite of all-cause mortality, all-stroke, reoperation or reintervention and cardiovascular hospitalization at 1 year. Secondary endpoints ...

Authors: Wang L, Ming Wang L, Chen W, Chen X Abstract The aim of this review was to describe recent advancements in the understanding of bicuspid aortic valve (BAV). BAV is the most common congenital cardiac anomaly, and affects between 0.46% and 1.37% of the population. There is a male predominance of approximately 3:1.While isolated BAV is found in certain patients, it is often associated with other congenital cardiac lesions, including dilatation of the thoracic aorta, coarctation of the aorta and abnormalities of the coronary anatomy. In most cases, it remains undetected until the patient contracts infective en...

CONCLUSIONS: SAVR after previous TAVI will become increasingly relevant. Due to the increasing use of TAVI in medium- or lower-risk patients, adequate strategies must be established since, in comparison to multimorbid patients, not taking action in these patients is not an option. Due to potentially high-risk patients and unique technical implications, SAVR after TAVI differs from conventional (redo) AVR. Under optimal conditions, acceptable survival rates can be achieved, but effective interdisciplinary approaches are essential. PMID: 28238237 [PubMed - in process]
