Background: Statistical shape atlases have been used in large-cohort studies to investigate relationships between heart shape and risk factors. The generalisability of these relationships between cohorts is unknown. The aims of this study were to compare left ventricular (LV) shapes in patients with differing cardiovascular risk factor profiles from two cohorts and to investigate whether LV shape scores generated with respect to a reference cohort can be directly used to study shape differences in another cohort.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Spontaneous coronary artery dissection (SCAD) is characterized by intramural hematoma in a coronary artery leading to partial or complete vessel obstruction. A 51-year-old female was hospitalized with acute myocardial infarction and cardiogenic shock. She was diagnosed with severe SCAD, affecting the proximal left coronary artery.

BACKGROUND Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lacks an intimal tear, influencing both clinical presentation and treatment strategy. This report describes a 74-year-old hypertensive woman with type A IMH and a penetrating atherosclerotic ulcer (PAU), managed with a hybrid surgical approach that combines external Dacron wrapping of the ascending aorta and endovascular stenting of the aortic arch with in-situ fenestration of the supra-aortic arteries.

People living with HIV are at higher risk of heart failure and associated left atrial remodeling compared to people without HIV. Mechanisms are unclear but have been linked to inflammation and premature aging. Here we obtain plasma proteomics concurrently with cardiac magnetic resonance imaging in two independent study populations to identify parallels between HIV-related and aging-related immune dysfunction that could contribute to atrial remodeling and clinical heart failure.
