MORPHOLOGICAL FEATURES OF CONSTRICTIVE PERICARDITIS

Российский кардиологический журнал, 2010
The features of pericardial morphology in constrictive pericarditis are described, based on the surgery material, which was obtained from 27 patients aged 5-77 years during pericardectomy.

Constrictive Pericarditis: A Challenging Diagnosis in Paediatrics

Case Reports in Cardiology, 2015
Constrictive pericarditis is an uncommon disease in children, usually difficult to diagnose. We present the case of a 14-year-old boy with a previous history of tuberculosis and right heart failure, in whom constrictive pericarditis was diagnosed.

Stability of quantum and Sharvin constrictions [PDF]

arXiv, 2011
Previously, the authors reported direct evidence of channel saturation and conductance quantization in atomic-sized gold constrictions through mechanical perturbation studies, and also showed that peaks in conductance histograms are insufficient in evaluating their mechanical stability [Armstrong et al., Phys. Rev. B 82, 195416 (2010)].

Real‐World Impact of Steerable Sheaths for Paroxysmal Atrial Fibrillation Catheter Ablation: The INSIGHT Study

Journal of Cardiovascular Electrophysiology, EarlyView.
Reductions in fluoroscopy time and dose and shorter PVI isolation times with the VIZIGO vs. non‐VIZIGO sheath: results of the real‐world, multicenter, INSIGHT cohort study. ABSTRACT Introduction In atrial fibrillation (AF) ablation procedures, the CARTO VIZIGO Bidirectional Guiding Sheath has previously shown promising results in reducing fluoroscopy ...

Constrictive pericarditis in a patient with sinus venosus atrial septal defect and anomalous right upper pulmonary venous return

Annals of Pediatric Cardiology, 2009
This is a report of a 49-year-old male, who presented with typical signs and symptoms of constrictive pericarditis. He was diagnosed with sinus venosus atrial septal defect (ASD) and anomalous right upper pulmonary venous return during his adolescence ...

Non-local impact of distal airway constrictions on patterns of inhaled particle deposition [PDF]

arXiv
Airway constriction and blockage in obstructive lung diseases cause ventilation heterogeneity and create barriers to effective drug deposition. Established computational particle-deposition models have not accounted for these impacts of disease. We present a new particle-deposition model that calculates ventilation based on the resistance of each ...

Tolerance for uncertainty and medical students' specialty choices: A myth revisited

Medical Education, EarlyView.
Abstract Background In 1962, the idea emerged that medical students' tolerance of uncertainty could determine their specialty choice. While some studies supported this claim, others refuted it, often using independently developed instruments. We explored whether the reported link between specialty choice and uncertainty tolerance is more myth than ...

Plasticity of the heart in response to changes in physical activity

The Journal of Physiology, EarlyView.
Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

Constrictive Pericarditis After a Stab Wound of the Chest

Annals of Internal Medicine: Clinical Cases
Constrictive pericarditis is an uncommon cause of diastolic heart failure resulting by impaired cardiac filling from an inelastic pericardium. We present a case of constrictive pericarditis in a 39-years-old man following thoracic penetrating trauma in ...

Anatomical description of malformations of the neck of the left atrial appendage

Clinical Anatomy, Volume 38, Issue 4, Page 471-479, May 2025.
Abstract The recently‐described left atrial appendage (LAA) neck is a truncated cone‐shaped structure that connects the LAA orifice to its lobe. It shows malformations in some cases, but their exact description and clinical significance are unknown. Therefore, the aim of this study was to provide a detailed anatomical and morphometric analysis of LAA ...
