Echocardiographic studies were completed among 190 people of the middle years second period, 108 people being female and 82 being male. The aortic ventricle size, the left atrium size and the right ventricle size, their mutual correlation, myocardial mass and the aortic ventricle myocardial mass index were studied. Anatomical heart changes revealed with the help of echocardiography depend on the type of the aortic-ventricle geometric model. Myocardial hypertrophy of the aortic ventricle is accompanied by the increase in the size of the right ventricle among the people of female genders at the statistically significant level. All the measures studied except the relative parietes thickness depend on the gender. There are gender differences of the aortic ventricle remodeling observed, i.e. higher rates of the aortic ventricle myocardial mass index among men, different dynamics of the aortic ventricle myocardial mass index measures depending on the geometric type of the aortic ventricle, their more prominent augmentation among women in the groups with eccentric left ventricle hypertrophy. A man's heart shows lower functional possibilities as compared to women.

Complicated infective endocarditis of the bioprosthetic mitral valve following the transcatheter mitral valve-in-valve procedure: a case report and literature review.
Eur Heart J Case Rep
January 2025
Tehran Heart Center, Cardiovascular Diseases Research Institute, Tehran University of Medical Sciences, North Kargar Ave, Tehran 1411713138, Iran.
Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.

Medical Image Processing Group, 602 Goddard building, 3710 Hamilton Walk, Department of Radiology, University of Pennsylvania, Philadelphia, PA 19104 (M.L., M.A., J.K.U., Y.T., C.W., N.P., S.M., D.A.T.). Electronic address:
Rationale And Objectives: Cardiovascular toxicity is a well-known complication of thoracic radiation therapy (RT), leading to increased morbidity and mortality, but existing techniques to predict cardiovascular toxicity have limitations. Predictive biomarkers of cardiovascular toxicity may help to maximize patient outcomes.
Methods: The machine learning optimal biomarker (OBM) method was employed to predict development of cardiotoxicity (based on serial echocardiographic measurements of left ventricular ejection fraction and longitudinal strain) from computed tomography (CT) images in patients with thoracic malignancy undergoing RT.
Cardiac Involvement and TBCK-Related Neurodevelopmental Disorder: Is It a New Feature of This Condition?
Am J Med Genet A

TBCK (TBC1 Domain-Containing Kinase) encodes a protein playing a role in actin organization and cell growth/proliferation via the mTOR signaling pathway. Deleterious biallelic TBCK variants cause Hypotonia, infantile, with psychomotor retardation and characteristic facies 3. We report on three affected sibs, also displaying cardiac malformations.

Background: Interventricular septal dissection is a critical disease characterized by the separation of the intraventricular septum into two layers, forming an intermediate layer with a cystic cavity that communicates with the root of the aorta or ventricle. It has low morbidity and high mortality rates.

Impact of measurement location on direct mitral regurgitation quantification using 4D flow CMR.
J Cardiovasc Magn Reson
January 2025
Department of Radiology, Feinberg School of Medicine, Northwestern University, Chicago, IL, USA. Electronic address:
Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the ideal location of a measurement plane remains unclear. This study aims to systematically examine how varying measurement locations affect RVol quantification and determine the optimal location using the momentum conservation principle of a free jet.
