Today, left atrial dissection is described as a rare complication of cardiac surgery, particularly after a mitral valve replacement. We report a rare case of left subacute atrial dissection occurred as a result of a domestic accidental fall. Transesophageal echocardiogram, angio-computed tomography, and magnetic resonance imaging showed an intramural formation with clear margins and a seamless cleavage with the posterolateral wall of the left atrium, which determined an obstacle to the ventricular filling. The patient was then operated in order to empty the hematoma and reattach the atrial wall.

Contraction and relaxation within the heart is controlled by the coordinated rise and fall of Ca levels within the cytosol of cardiomyocytes. This requires Ca to be moved between subcellular and extracellular compartments with each cardiac cycle, since Ca is not destroyed or broken down by the excitation-contraction and relaxation cycles. Many cardiac pathologies alter Ca homeostasis and can lead to impaired contraction, incomplete relaxation, and arrhythmias.

Human myocardial function can be investigated in the laboratory using human atrial trabeculae. These multicellular preparations provide a translatable model for assessing the ex vivo contractility, electrophysiology, and ionic and metabolic underpinnings of human cardiac muscle. Here, we detail the materials and methods required to determine the baseline function of a human atrial trabecula, from dissection to stimulation.

Giant cell arteritis (GCA) is an inflammatory vasculitis affecting large and medium-sized arteries, leading to complications such as arterial dissection, blindness, and stroke. Rarely, GCA presents with Horner's syndrome due to sympathetic neuron involvement from arterial inflammation. This case report discusses an 82-year-old female with hypertension, atrial fibrillation, and arthritis who presented with a 24 h history of right eye ptosis, blurred vision, dizziness, and aching eye pain.

Objectives: We sought to assess the effect of postoperative renal failure (RF) on outcomes and identify predictors of chronic kidney disease (CKD) post-ATAAD.
Methods: This retrospective single-center analysis included all adults with ATAAD from 2011-2023. Patients were stratified into renal failure (RF) and no RF groups.

Aortic dissection (AD) is a life-threatening emergency involving a tear in the aortic intima, leading to a false lumen. Atrial fibrillation (AF) can complicate AD, increasing management challenges and mortality risks. We report a 67-year-old male with no known past medical history who presented with a 1-day history of abdominal pain.
