Transfer Learning Video Classification of Preserved, Mid-Range, and Reduced Left Ventricular Ejection Fraction in Echocardiography.

Identifying patients with left ventricular ejection fraction (EF), either reduced [EF < 40% (rEF)], mid-range [EF 40-50% (mEF)], or preserved [EF > 50% (pEF)], is considered of primary clinical importance. An end-to-end video classification using AutoML in Google Vertex AI was applied to echocardiographic recordings. Datasets balanced by majority undersampling, each corresponding to one out of three possible classifications, were obtained from the Standford EchoNet-Dynamic repository.

Beware of the LASP! A structure with thrombogenic potential.

The left atrial septal pouch (LASP) is a recently identified anatomical variant of the interatrial septum. It is the result of the incomplete fusion of septum primum and septum secundum and defined as a recessus communicating with the left atrium without interatrial shunt. Such anatomical feature has been suspected representing a potential thrombogenic source, but its actual role as risk factor for cryptogenic stroke still remains unclear.

On-Pump Coronary Artery Bypass Graft: The State of the Art.

Background: Coronary artery bypass grafting (CABG) remains the standard of care for patients with coronary artery disease (CAD). Debate exists concerning several factors, which include percutaneous coronary intervention (PCI) vs. CABG, single vs.

Electrolyte Disorders as Triggers for Takotsubo Cardiomyopathy.

Unlabelled: A 56-year-old woman presented with cognitive impairment, confusion and slowed speech, muscle cramps and peripheral paraesthesia preceded by vomiting. Blood tests revealed severe hypokalaemia, hyponatremia, hypomagnesemia and hypocalcaemia. Following a diagnosis of Takotsubo cardiomyopathy based on ultrasonography, the patient was treated with electrolyte supplementation and recovered within 48h.
