An Intraoperative Fluoroscopic Predictor of Successful Micra Implantation on the Right Ventricular Mid‐Septum

open access: yesJournal of Arrhythmia
Background The Micra transcatheter pacing system has been adopted globally. However, the procedural parameters for safe Micra implantation on the ventricular wall, particularly in the mid‐septum, remain unknown.

Is there a utility for QRS dispersion in clinical practice? [PDF]

open access: yes, 2017
Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Impaired Left Ventricular Longitudinal Function in Idiopathic Pulmonary Arterial Hypertension Children

open access: yesJournal of Interdisciplinary Medicine, 2016
Background: Pulmonary arterial hypertension is associated with right ventricular dilation and failure. As a result, left ventricular geometry is affected by shifting of the interventricular septum towards the left ventricle.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

open access: yes, 2008
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

High implantation technique during CoreValve replacement in a high-risk aortic stenosis patient with a sigmoid left ventricular hypertrophy and a large aortic annulus

open access: yesTürk Kardiyoloji Derneği Arşivi, 2015
The appropriate size, accurate alignment and correct positioning of transcatheter aortic valves (TAVIs) at the point of deployment are emphasized as key factors in placement and fixation of the devices.

Echocardiography during submaximal isometric exercise in children with repaired coarctation of the aorta compared with controls [PDF]

open access: yes, 2019
Objective Patients with repaired coarctation (RCoA) remain at higher risk of cardiac dysfunction, initially often only detected during exercise. In this study, haemodynamics of isometric handgrip (HG) and bicycle ergometry (BE) were compared in patients ...

Long‐Term Outcomes of Reduced‐Intensity Conditioning Hematopoietic Stem Cell Transplantation for Patients With Systemic Sclerosis With Impaired Cardiac Function

open access: yesArthritis &Rheumatology, EarlyView.
Objective High‐intensity conditioning autologous hematopoietic stem cell transplantation (AHSCT) is standard of care for patients with advanced systemic sclerosis (SSc). The role of reduced‐intensity conditioning (RIC) before AHSCT in this population remains unclear.
