Functional and structural safety of the myocardium following 6-hour preservation at 4-6 degrees C in ion-balanced cardioplegic solution alone or in combination with pharmacological corrective was evaluated in rats. Langendorff and Neely model of isolated heart perfusion was used. The addition of creatine phosphate in a conservation of 10 mM/l to the solution or donor pretreatment with 70 mg/kg vitamin E was found to potentiate the protective properties of the solution under deep hypothermia. The combined use of the agents proved to warrant the initial intact structural and functional status of the rat myocardium.

In patients with cystic fibrosis (CF), repeated cycles of infection and inflammation eventually lead to fatal lung damage. Although diminished mucus clearance can be restored by highly effective CFTR modulator therapy, inflammation and infection often persist. To elucidate the role of the innate immune system in CF etiology, we investigated a CF pig model and compared these results with those for preschool children with CF.

Objective: 3p deletion syndrome is a rare monosomal disease that encompasses deletions throughout the short arm of chromosome 3. It is often in the distal region (3p25-pter), but variations in breakpoints and a complex clinical manifestation exist, with congenital heart defects being considered rare. We present the first case of hypoplastic left heart syndrome and minor dysmorphic features associated with 3p- syndrome.

Background: The optimal imaging modality for selecting the device size in patients with atrial fibrillation undergoing one-stop left atrial appendage occlusion (LAAO) with concomitant pulmonary vein isolation (PVi) remains undefined. We compared preprocedural 3-dimensional computed tomography (3D CT) with intra-procedural transesophageal echocardiography (TEE) and left atrial appendage (LAA) angiography in guiding one-stage PVi and LAAO.
Methods: We measured the LAA ostium diameter using an interactive 3D CT system with a central line-based approach and compared these measurements with those from intra-procedural TEE and angiography, and the actual device size.

Significance: Radiofrequency ablation to treat atrial fibrillation (AF) involves isolating the pulmonary vein from the left atria to prevent AF from occurring. However, creating ablation lesions within the pulmonary veins can cause adverse complications.
Aim: We propose automated classification algorithms to classify optical coherence tomography (OCT) volumes of human venoatrial junctions.

Introduction: Cardiovascular diseases represent the leading cause of mortality worldwide. This category includes cerebrovascular disease, ischemic heart disease, and peripheral vascular disease. Secondary prevention is effective for patients with a history of cardiovascular events, with antihypertensives, statins, and acetylsalicylic acid being the most prescribed drugs.
