Submaximal 2‐day cardiopulmonary exercise testing to assess exercise capacity and post‐exertional symptom exacerbation in people with long COVID

Experimental Physiology, EarlyView.
Abstract Long COVID has a complex pathology and a heterogeneous symptom profile that impacts quality of life and functional status. Post‐exertional symptom exacerbation (PESE) affects one‐third of people living with long COVID, but the physiological basis of impaired physical function remains poorly understood. Sixty‐eight people (age (mean ± SD): 50 ±

Preoperative extracorporeal mechanical circulatory support for patients with acute severe mitral valve regurgitation due to papillary muscle necrosis

Вестник трансплантологии и искусственных органов
Background. Acute mitral valve insufficiency has a high mortality rate (up to 100%). Mechanical circulatory support and emergency surgery can improve the survival of this patient cohort.Objectives: to analyze a 12-year single-center experience of ...

Genotype–Phenotype Correlations, Treatment, and Prognosis of Children With Early‐Onset (Neonatal) Marfan Syndrome

Clinical Genetics, Volume 108, Issue 2, Page 134-145, August 2025.
Early‐onset Marfan syndrome (eoMFS) is a rare disorder with atrioventricular valve insufficiency being the most severe symptom. We propose to regard eoMFS as a spectrum, ranging from a severe disorder life‐threatening already before or immediately after birth, to a disorder with a better survival rate, creating a window for atrioventricular valve ...

P Wave Dispersion is Increased in Pulmonary Stenosis [PDF]

, 2006
Aim: The right atrium pressure load is increased in pulmonary stenosis (PS) that is a congenital anomaly and this changes the electrophysiological characteristics of the atria.

Genotypic and Phenotypic Characterization of Seven Individuals With Predicted Bone Morphogenetic Protein 2 (BMP2) Haploinsufficiency

Clinical Genetics, Volume 108, Issue 2, Page 199-205, August 2025.
BMP2 haploinsufficiency is known to be associated with short stature, skeletal malformations, specific craniofacial traits and cardiac malformations. This study including individuals with predicted BMP2 haploinsufficiency provides additional insight regarding less established and sometimes controversial phenotypes such as degree of developmental delay,

Double-orifice mitral valve and an associated malformation: secundum atrial septal defect [PDF]

, 2004
The authors report a case of double-orifice mitral valve (DOMV) which showed mitral stenosis and mild insufficiency. An associated anomaly was secundum atrial septal defect. DOMV is an unusual congenital heart defect.

Nonlinear control of a hybrid pneumo‐hydraulic mock circuit of the cardiovascular system

International Journal of Robust and Nonlinear Control, Volume 35, Issue 10, Page 3962-3998, 10 July 2025.
Abstract Hybrid cardiovascular mock circuits (HMC), designed for dynamic testing of Ventricular Assist Devices (VAD), offer physiologic accuracy by sequestering model complexity in silico and ease of construction by reducing number of model elements in vitro.

Hemangioma of the Atherosclerotic Changed Aortic Valve

Case Reports in Cardiology, 2019
The incidence of heart valve hemangioma is very low and is mostly observed in the mitral and tricuspid valve. In 2006, two cases of aortic valve hemangioma were reported for the first time, including one with calcifying aortic valve stenosis.
