A new Valsalva blowing device in the diagnosis of right-to-left shunt using contrast-enhanced transcranial Doppler ultrasound

European Journal of Medical Research
Background Patent foramen ovale (PFO) is a remnant of normal fetal anatomy and is present in approximately 25% of adults. PFO mainly causes right-to-left shunt (RLS). Clinical identification of RLS is crucial for certain patients, particularly those with

Considerations for drug trials in hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Diagnosis and operative repair strategy of an underlying tegmen defect presenting with spontaneous otogenic pneumocephalus after Valsalva maneuver

Interdisciplinary Neurosurgery, 2021
Background: The tegmen tympani and mastoideum are insidious locations of bony dehiscence. Large defects may result in encephalocele, cerebrospinal fluid leak, recurrent meningitis, and intracranial abscess.

Multicompartmental prolapse: A comparative study between clinical examination and ultrasound

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The accurate diagnosis of multicompartment pelvic organ prolapse (POP) is fundamental to surgical success. This study aims to compare the diagnostic performance of transperineal ultrasound against clinical examination (pelvic organ prolapse quantification, POP‐Q) for the detection of compartmental defects in patients with ...

Pelvic venous disorders in women: Diagnosis and management for gynecologists

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Pelvic venous disorders (PeVD) are an underrecognized yet significant cause of chronic pelvic pain (CPP) in reproductive‐aged women, characterized by venous reflux, obstruction, or both. This clinical opinion provides a practical overview of PeVD for gynecologists, outlining its pathophysiology, common presentations, diagnostic approach, and ...

Autonomic modulation in patients with heart failure increases beat-to-beat variability of ventricular action potential duration [PDF]

, 2017
Background: Exaggerated beat-to-beat variability of ventricular action potential duration (APD) is linked to arrhythmogenesis. Sympathetic stimulation has been shown to increase QT interval variability, but its effect on ventricular APD in humans has not

Phenotypic Subtypes of Obstructive Eustachian Tube Dysfunction as Defined by Cluster Analysis

The Laryngoscope, EarlyView.
Obstructive ETD encompasses five clinically distinct phenotypes, ranging from mild, post‐upper respiratory infection presentations to chronic, bilateral disease driven by sinusitis and reflux. These were identified through hierarchical cluster analysis of 490 patients using seven key clinical variables.

Transcranial doppler ultrasonography should it be the first choice for persistent foramen ovale screening? [PDF]

, 2014
BACKGROUND: Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE ...
