Benefit of Transcatheter Aortic Valve Replacement in Patients With Paradoxical Low-Flow Low-Gradient Versus High-Gradient Aortic Stenosis and Preserved Left Ventricular Function

Circulation. Cardiovascular Interventions, 2021
Background: There is conflicting data regarding transcatheter aortic valve replacement in patients with paradoxical low-flow, low-gradient aortic stenosis (pLFLG-AS).

Role of Echocardiography Before Transcatheter Aortic Valve Implantation (TAVI) [PDF]

, 2016
Aortic stenosis (AS) is the most common primary valve disorder in the elderly with an increasing prevalence; transcatheter aortic valve implantation (TAVI) has become an accepted alternative to surgical aortic valve replacement (AVR) in the high risk or ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Dilemma in the therapeutic management of low-gradient aortic stenosis

Current Opinion in Cardiology, 2017
Grading of aortic stenosis is essential in aortic stenosis management patients. However, despite clear thresholds provided in the guidelines, up to 30% of patients have discordant grading of aortic stenosis. The management of patients with low gradients/velocity despite tight aortic valve area is challenging.Recent studies demonstrated that patients ...

Natural History of Paradoxical Low-Gradient Severe Aortic Stenosis [PDF]

Circulation: Cardiovascular Imaging, 2014
Background— Up to 30% of patients with severe aortic stenosis (SAS; indexed aortic valve area <0.6 cm 2 /m 2 ) present with low transvalvular gradient despite a normal left ventricular ejection fraction.

Mathematical modeling of thrombus formation in idealized models of aortic dissection: Initial findings and potential applications [PDF]

, 2016
Aortic dissection is a major aortic catastrophe with a high morbidity and mortality risk caused by the formation of a tear in the aortic wall. The development of a second blood filled region defined as the “false lumen” causes highly disturbed flow ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Prevalence, predictors, and prognostic implications of residual impairment of functional capacity after transcatheter aortic valve implantation [PDF]

, 2017
Background: Patients with degenerative aortic stenosis (AS) referred for transcatheter aortic valve implantation (TAVI) typically have advanced cardiac and vascular adverse remodeling and multiple comorbidities and, therefore, might not recover a normal ...

Non-compaction cardiomyopathy with low-gradient aortic valve stenosis [PDF]

European Heart Journal, 2008
A 73-year-old man presented to the emergency department with dyspnea of 2 days duration. Auscultation of the precordium was notable for a grade 2/6 systolic murmur. Echocardiography revealed a highly impaired left ventricular function and a calcified aortic valve stenosis with a …
