Non‐Invasive Prenatal Testing by Cell‐Free DNA (cfNIPT) for Detecting Turner Syndrome With Mosaicism and Structural Variants—Prenatal Findings and Postnatal Outcomes

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner Syndrome (TS) is a sex chromosomal disorder associated with karyotype heterogeneity. Although TS can be associated with severe prenatal findings, most often linked to the 45, X karyotype, the majority of TS fetuses have no overt phenotype, resulting in delayed diagnosis and management.

Left ventricular outflow tract to left atrium fistula as a complication of aortic root repair

open access: yesIHJ Cardiovascular Case Reports, 2023
A fistula between the left ventricular outflow tract and left atrium is a very rare phenomenon. In this case report, we will introduce a Marfan patient who underwent an aortic root repair, leading to a complication of a left ventricular outflow tract to ...

Apical ballooning syndrome complicated by acute severe mitral regurgitation with left ventricular outflow obstruction – Case report

open access: yesJournal of Cardiothoracic Surgery, 2007
Background Apical ballooning syndrome (or Takotsubo cardiomyopathy) is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an

Expert Strategies: Skull Base Reconstruction—Global Perspectives, Insights, and Algorithms through a Mixed Methods Approach

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective There is limited consensus on endoscopic skull base surgery (ESBS) reconstruction principles. This study aims to generate comprehensive themes regarding ESBS reconstruction by pooling the experiences of ESBS experts, with comparison to a literature review of current published evidence.

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]

open access: yes, 2015
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study investigated changes in pulmonary artery hemodynamics using a Flowire catheter and evaluated the accuracy of Doppler echocardiography in dogs with acute pulmonary thromboembolism (PTE). Ten healthy beagles were anesthetized, and acute pulmonary hypertension (PH) was induced by injecting 300‐μm dextran microspheres.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Conventional cardiopulmonary resuscitation-induced refractory cardiac arrest due to latent left ventricular outflow tract obstruction due to a sigmoid septum: a case report

open access: yesJournal of Medical Case Reports, 2018
Background Patients with left ventricular outflow tract obstruction who do not exhibit a dynamic pressure gradient at rest, experience pressure gradient increases of ≥ 30 mmHg only during specific situations; this is called latent left ventricular ...
