January, 27, 2021 — The U.S. Food and Drug Administration (FDA) has granted Occlutech a Breakthrough Device designation for its first-in-class, implantable Atrial Flow Regulator (AFR) for heart failure (HF) patients with preserved (HFpEF) or reduced (HFrEF) ejection fraction. The AFR is used in patients who, despite optimal medical therapy, experience worsening symptoms. The AFR maintains an interatrial shunt with a predetermined diameter allowing for controlled blood flow from the left to the right atrium enabling the left atrium to decompress and lower left atrial pressure. Reduced left atrial pressure has been shown to reduce heart failure symptoms and improve exercise tolerance. Breakthrough Device Designations aim to accelerate the development, assessment, and approval of new treatments in severe diseases, including a prioritized review all the way through market approval. "It is an important milestone for us to have received this second breakthrough designation for our AFR device." said Sabine Bois, CEO Occlutech Group. "After receiving the first Breakthrough Device designation for pulmonary arterial hypertension (PAH) in December 2020, the heart failure indication addresses a substantial market with rapid growth and only limited options for the treatment for critically ill patients. We are looking forward to developing an important new therapy and working closely with the FDA on both indications." HF is a serious condition characterized by the heart's inability to pump an adequate blood supply to the body. Worldwide, HF affects over 30 million people, and the lifetime risk of HF increases with age, with over 50% of hospitalizations of persons aged 65 or older attributable to HF. Heart Failure Symptoms include fatigue, palpitations, and exertional dyspnea. HF may result from disorders of the pericardium, myocardium, endocardium, heart valves, great vessels, or specific metabolic abnormalities. These disorders affect the heart's structure or function, which results in reduced cardiac output and/or elevated intracardiac pressures at rest or during exercise. When HF is left untreated, symptoms gradually worsen, resulting in increased morbidity, clinically driven hospitalizations, and higher mortality. The AFR is not approved in the United States.  Product availability is subject to local regulatory clearance. The AFR is under clinical investigation for use in patients with pulmonary arterial hypertension and use in these patients is limited by applicable national laws.

What are the differences between arteries and veins? Read on to find out about these blood vessels, plus other types, and how the cardiovascular system works.

The document discusses cardiovascular physiology including the factors that determine cardiac output, blood pressure regulation, coronary artery anatomy, and hemodynamic monitoring. Specifically, it states that cardiac output is determined by stroke volume and heart rate. It defines normal ranges for cardiac index, mean arterial pressure, and cardiac output. It also reviews the anatomy of the coronary arteries and discusses right versus left coronary artery dominance.

To perform Doppler ultrasonography of theLower extremity arteries, the operator should be familiar with the arterial anatomy of the lower extremities, basic scanning techniques, and the parameters used in color and pulsed-wave Dopplers. Doppler ultrasonography of the lower extremity arteries is a valuable technique, although it is less frequently indicated for peripheral arterial disease than for deep vein thrombosis or varicose veins. Ultrasonography can diagnose stenosis through the direct visualization of plaques and through the analysis of the Doppler waveforms in stenotic and poststenotic arteries. To perform Doppler ultrasonography of the lower extremity arteries, the operator should be familiar with the arterial anatomy of the lower extremities, basic scanning techniques, and the parameters used in color and pulsed-wave Doppler ultrasonography.

the Radiologist | Radiology on Instagram: "CHEST CT ANATOMY Here we are looking at CT anatomy of the mediastinum at two levels: 1️⃣Level of the great vessels ▫️Look for the three great vessels: brachiocephalic trunk, left common carotid artery and left subclavian - the mnemonic I used to remember this is ‘Big Cheesy Smile’ although there are others. How do you remember them? ▫️The banana shaped vessel anterior to these is the left brachiocephalic vein which joins the right brachiocephalic vein to form the SVC 2️⃣Level of the pulmonary trunk ▫️Here you see the pulmonary trunk dividing into right and left main pulmonary arteries ▫️At this level the diameter of the main pulmonary trunk should not be more than the diameter of the ascending aorta - if it is, consider pulmonary arterial hyp
