Cardiology icons 2: Prof Chris Orton on mechanisms of mitral valve disease and trans catheter edge-to-edge repair

Message our hosts, Kieran and Jose.Season 3 of The Animal Heartbeat is all about the Veterinary Cardiology Icons - those who walk among us as legends of the veterinary cardiology world.This episode features Professor Chris Orton of Colorado State University. Prof Orton has been a leader in the field of canine heart surgery for over thirty years, having worked to develop both open heart surgery techniques on cardiopulmonary bypass and minimally invasive techniques to treat valve disease. Chris is known as a cardiologist and a surgeon, but also has a strong bench-top research background, evaluating the mitral valve and the mechanisms of degenerative disease.Join our hosts, Jose and Kieran, as they discuss Prof Orton's research experience and his experience over the last 3-years of trans-catheter edge-to-edge mitral valve repair, patient considerations and outcomes.

Message our hosts, Kieran and Jose.Season 3 of The Animal Heartbeat is all about the Veterinary Cardiology Icons - those who walk among us as legends of the veterinary cardiology world.This episode features Professor Sydney Möise, of Cornell University, CV Starr Professor Emerita of Cardiology. Prof Möise's research and education output on cardiac arrhythmias has shaped how many of us think about electrical problems of the heart, and she has become known as a pioneer of ambulatory ECG assessment of heart rate variability. Her recent collaborations with Wyatt Flanders, her son, has given the veterinary cardiology world free access to dynamic and 3D Poincaré plots in dogs, broadening our understanding of conduction system disease in animals.Join our hosts, Kieran and Jose, as they discuss canine cardiac arrhythmias with a legend in their field.

Message our hosts, Kieran and Jose.Hallowe'en is a time for bringing people together and sharing scary stories. Did you ever hear the one about the young, newlywed couple who broke down on the country road by the old psychiatric hospital...? No need to worry - this strictly scientific discussion sees Kieran and Jose share stories of the most terrifying heart conditions that they know of. The recording was plagued by unexplained technical difficulties... Jose was was delayed by a closed motorway, and Kieran was recording from a possibly haunted house. Add to that a specially remixed theme tune, and you can't help be in the Hallowe'en spirit after listening to our final FINAL episode of season 2.

Message our hosts, Kieran and Jose.Mitral valve disease is the most common heart disease diagnosed in dogs. Our understanding of it affects how we manage a wide range of scenarios, from asymptomatic heart murmurs detected at annual vaccination, to patients with respiratory signs or those about to undergo sedation or anaesthesia, or simply receive fluid therapy. Join Professor Michele Borgarelli, from the Virginia Maryland College of Veterinary Medicine, as he speaks to Kieran and Jose about an innovative dataset on over 6000 dogs with mitral valve disease, the LOOK-Mitral Registry, and how research like this can inform decision making in the clinic.

Message our hosts, Kieran and Jose.Vets understand that the cornerstone of treatment for congestive heart failure in animals is the use of loop diuretics, such as furosemide. But resistance occurs in all patients over time, and intensification of diuretic treatment is a vital part of managing patients with clinical signs - both for left- and right-sided manifestations of disease. How are we best to approach this, and what can we do when using diuretic drugs to make the best decisions that will have positive benefits for our patients? Join Jose and Kieran as they welcome Prof Mark Oyama, from the University of Pennsylvania, to discuss strategic use of diuretic drugs in the clinic and the most up to date research on how to judge diuretic efficacy in acute and chronic heart failure patients.

Message our hosts, Kieran and Jose.As veterinary cardiologists, we rely on ultrasound every day to assess cardiac structure and function. Whilst important for owners to understand the cause of a murmur or clinical signs, we use echo to make critical decisions about when and how to treat, and inform conversations with owners about prognosis. The impact of echo on the lives of our patients is greater than anything else we do. But it may not be as accurate as you think... Learn how to best use echocardiography to make decisions, and which echo measurements may be best to select for accuracy, by joining Jose and Kieran as they speak to Dr Lance Visser, Assistant Professor at Colorado State University, about his research work in veterinary echo and his advice on how best to use this fundamental tool.
