O diagnóstico da obstrução da via de saída do ventrículo esquerdo na cardiomiopatia hipertrófica The diagnosis of left ventricular outflow tract obstruction in hypertrophic cardiomyopathy

Arquivos Brasileiros de Cardiologia, 2012
A cardiomiopatia hipertrófica é uma doença genética prevalente caracterizada por hipertrofia ventricular esquerda, em que obstrução dinâmica da via de saída com geração de gradiente subaórtico incide em repouso em 30% dos casos.

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Myocardial collagen deposition and inflammatory cell infiltration in cats with pre-clinical hypertrophic cardiomyopathy [PDF]

, 2015
The histological features of feline hypertrophic cardiomyopathy (HCM) have been well documented, but there are no reports describing the histological features in mild pre-clinical disease, since cats are rarely screened for the disease in the early ...

Quantitative Assessment of Myocardial Perfusion in Physiological and Pathological Hypertrophy Using Myocardial Contrast Echocardiography

Clinical Cardiology, Volume 49, Issue 5, May 2026.
Myocardial hypertrophy can be classified into physiological and pathological types based on etiology, with significant differences in clinical outcomes. This study utilized myocardial contrast echocardiography to quantitatively assess myocardial microcirculatory perfusion in patients with different types of hypertrophy.

Monro-Kellie 2.0: The dynamic vascular and venous pathophysiological components of intracranial pressure [PDF]

, 2016
For 200 years, the ‘closed box’ analogy of intracranial pressure (ICP) has underpinned neurosurgery and neuro-critical care. Cushing conceptualised the Monro-Kellie doctrine stating that a change in blood, brain or CSF volume resulted in reciprocal ...

Teriparatide in Two Patients With Mucopolysaccharidosis Type IVB

JIMD Reports, Volume 67, Issue 3, May 2026.
ABSTRACT Mucopolysaccharidosis Type IV is a multisystem lysosomal storage disease characterized by severe skeletal dysplasia resulting from impaired degradation of the glycosaminoglycans keratan sulfate and chondroitin‐6‐sulfate. The condition is classified into Types A and B based on the underlying enzyme deficiency.

Real-time Assessment of Right and Left Ventricular Volumes and Function in Children Using High Spatiotemporal Resolution Spiral bSSFP with Compressed Sensing [PDF]

, 2018
Background: Real-time (RT) assessment of ventricular volumes and function enables data acquisition during free-breathing. However, in children the requirement for high spatiotemporal resolution requires accelerated imaging techniques.

Left ventricular fibrosarcoma in a 4‐year‐old labrador

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 4‐year‐old, male, neutered labrador presented for investigations into a single episode of collapse and an intracardiac mass. Echocardiography and computed tomography confirmed the presence of a large soft tissue mass within the left ventricular lumen, which nearly obstructed the left ventricular outflow tract.
