Analysis looks at role type of valve plays in patient outcomes post-TAVR
(Society for Cardiovascular Angiography and Interventions) Results from 'Impact of valve design and bivalirudin vs. unfractionated heparin for anticoagulation in transcatheter aortic valve replacement: Results from the BRAVO-3 trial' were presented today as a late-breaking clinical trial at the Society for CardiovascularAngiography and Interventions (SCAI) 2017 Scientific Sessions in New Orleans.
CONCLUSIONS: BAV is an effective treatment modality for AS in children of all age groups, which postpones the need for surgical treatment. Late follow-up reveals progression of AR. A greater reduction in PGmax is a risk factor for at least moderate AR directly post BAV, which results in the progression of AR at late follow-up and the need for performing heart surgery sooner.

Authors: Iida Y, Fujii S, Sawa S, Shimizu H Abstract A 50-year-old man who suffered from dyspnea on effort with hearing loss was referred to our hospital. Computed tomography angiography revealed a giant 90-mm diameter ascending aortic aneurysm with severe calcification and neck vessel occlusion. Transthoracic echocardiography revealed moderate-to-severe aortic regurgitation. His condition was diagnosed as Takayasu arteritis and he underwent aortic valve reimplantation with total arch replacement. Postoperative computed tomography angiography showed complete aneurysm resection and the patient was discharged without...
ConclusionThis case demonstrates that QAV stenosis can be treated using TAVI with good clinical outcomes.
ConclusionsThe proposed algorithm is the first application of CNN to aortic valve planimetry and achieves an accuracy on par with proposed automated methods for localization and approaches an expert-level accuracy for orientation. The method relies on no heuristic specific to the aortic valve and may be generalizable to other anatomical features.
We present the case of a 22-year-old young lady following Rastelli repair with chronic right heart failure. Weighing the risk of several offered surgical options, she underwent successful PPVI following minimally invasive direct coronary artery bypass (MIDCAB) procedure. A 22-year-old patient underwent successful percutaneous pulmonary valve implantation despite coronary compression during test ballooning of the right ventricle to pulmonary artery conduit. A combination of MIDCAB and PPVI was performed to avoid a conduit exchange. PMID: 32145193 [PubMed - as supplied by publisher]
Transcatheter aortic valve replacement (TAVR) has become the preferred procedure for aortic valve replacement.1 Preprocedural multidetector computed tomographic (MDCT) imaging for aortic root analysis and prosthetic valve sizing is considered standard of care.2 However, the use of iodinated contrast agent during MDCT angiography bears a significant nephrotoxicity risk in patients with chronic severe kidney failure. Three-dimensional (3D) transesophageal echocardiographic (TEE) imaging is considered a valuable alternative for aortic root sizing in this population.
We present the first case with history of repaired coarctation with multiple spontaneous intercostal artery aneurysmal rupture.

Abstract BACKGROUND: Bicuspid aortic valve-associated ascending thoracic aortic aneurysms (BAV-aTAA) carry a risk of acute type A dissection. Biomechanically, dissection may occur when wall stress exceeds wall strength. Our aim was to develop patient-specific computational models of BAV-aTAAs to determine magnitudes of wall stress by anatomic regions. METHODS: Patients with BAV-aTAA diameter>4.5cm (n=41) underwent ECG-gated computed tomography angiography. Three-dimensional aneurysm geometries were reconstructed after accounting for pre-stress and loaded to systemic pressure. Finite element analyses were p...
This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...
