Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

BMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

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 …

Adipocytes in Aortic Stenosis: Association With Clinical and Morphological Indices

Clinical Anatomy, EarlyView.
ABSTRACT Recently, great attention has been given to understanding the new pathogenetic mechanisms underlying aortic stenosis (AS). The study aims to understand the role of mature adipocytes in AS and their association with histologic, clinical, and echocardiographic data, an area previously overlooked in AS research.

Balloon Valvuloplasty of Aortic Valve Stenosis in Childhood: Midterm Results in a Children's Hospital, Mansoura University, Egypt

Clinical Medicine Insights: Cardiology, 2012
Background Balloon valvuloplasty was established as an alternative to surgery for treatment of aortic valve stenosis in childhood. Acute complications after balloon dilatation including aortic insufficiency or early death were described.

P152 THE EFFECT OF SURGICAL AORTIC VALVE REPLACEMENT ON AORTIC STIFFNESS AND THE PROGNOSTIC ROLE OF AORTIC STIFFNESS ON SURGICAL SUCCESS

Artery Research, 2018
Purpose/Background/Objectives: Aortic stiffness and hemodynamics are established biomarkers for cardiovascular events. Surgical aortic valve replacement (SAVR) remains the first choice of treatment in most patients with aortic stenosis.

Transfemoral aortic valve replacement in a nonagenarian with aortic stenosis and cardiac amyloidosis: case report

Journal of Cardiothoracic Surgery, 2022
Background Cardiac amyloidosis (CA) is diagnosed with increasing frequency in the elderly population with severe aortic stenosis (AS), especially with the low-flow, low- gradient phenotype. Prognosis is poor with no treatment.

Aortic Stenosis Suspected to Be Severe Despite Low Gradients [PDF]

Circulation: Cardiovascular Imaging, 2014
The American College of Cardiology/American Heart Association and European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines generally recommend aortic valve replacement (AVR) in patients with severe aortic stenosis (AS) who have symptoms, have left ventricular (LV) systolic dysfunction, or undergo coronary artery bypass

Superiority of the Rockwood Clinical Frailty Scale for Assessing Long‐Term Outcome in Patients Undergoing Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Frailty is associated with poorer short‐term outcomes after transcatheter aortic valve implantation (TAVI), and national guidelines recommend an assessment of frailty as part of the decision‐making process. However, multiple frailty indices are currently used in clinical practice, and it is unclear which has the best discrimination ...

Commissural Misalignment Following Valve‐in‐Valve Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data on commissural misalignment (CMA) during valve‐in‐valve transcatheter aortic valve implantation (ViV‐TAVI) for valve failure after surgical aortic valve replacement (SAVR) is scarce. Aims To study the impact of CMA on clinical and hemodynamic outcomes following ViV‐TAVI for failed SAVR.
