P Wave Dispersion is Increased in Pulmonary Stenosis [PDF]

, 2006
Aim: The right atrium pressure load is increased in pulmonary stenosis (PS) that is a congenital anomaly and this changes the electrophysiological characteristics of the atria.

Diagnosis of “Paradoxical” Low-Gradient Aortic Stenosis Patients

Journal of the American College of Cardiology, 2013
The report by Lauten et al. [(1)][1] investigates a very important clinical presentation—“paradoxical” low-gradient aortic stenosis (PLG AS). This is a diagnostic challenge, and their work definitely improves our understanding of this problem.

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.

Case report: Stenosis turned leak … and turned stenosis—complications of paravalvular prosthetic leak closure with a plug device

Frontiers in Cardiovascular Medicine, 2023
BackgroundParavalvular leak is one of the most common complications and is among the most important prognostic factors of short- and long-term mortality after transcatheter aortic valve implantation (TAVI). Percutaneous valvular leak repair constitutes a

Intentional Stent Fracture to Accommodate Growth After Coarctation Stenting in an 860‐g Neonate

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Congenital aortic coarctation in neonates and children can be managed with transcatheter stent implantation, but this approach raises the issue of how to accommodate the fixed stent structure within the growing vessel. Case Summary A 15‐month‐old boy, born prematurely with critical aortic coarctation, was treated at 1 week of age ...
