The procedure is called radiocatheter ablation. It's used regularly in humans but there are only three or four centres in the world that perform the procedure routinely on veterinary patients and Pedro is the only veterinary cardiologist currently performing it in the UK.
DVS says the procedure can achieve a cure for previously incurable conditions, without the need for further medical treatment with drugs that have potential side effects. It involves inserting catheters into veins in the legs and neck and then guiding them into the heart. Electrical signals can be recorded to show where the abnormal heartbeats are generated ('mapping'). Once this is achieved, heat is used to destroy the tiny abnormal area of the heart muscle and make the arrhythmia disappear ('zapping'). Recovery is straightforward and the condition can be completely cured.
Jake, a three-year-old Labrador Retriever, is one of seven dogs that have been cured by Pedro and the team so far.
Jake suffered from life-threatening cardiac arrhythmia, causing his heart to beat at over 250 beats per minute for prolonged periods. Such an elevated heart rate cannot be sustained for long and may result in damage to the heart muscle. Jake had been diagnosed a number of months ago and initially responded to anti-arrhythmic drugs. However, the drugs stopped working and his heart was sustaining damage and showing early signs of weakness. The radiocatheter ablation cured his condition completely and he can now lead a normal healthy life.
Jake’s owner, Mrs Chapman from Staffordshire, said: "We would like to thank everyone at Davies Veterinary Specialists for looking after Jake during his three day stay in April 2016. Special thanks to Pedro Oliveira and his cardiac team for operating on Jake and correcting his heart condition. Jake is no longer taking any medication and has made a full recovery. We now have a much happier, more energetic Labrador, ready for walks and play at every opportunity. Jake seems to have a smile on his face everyday now and is enjoying life to the full."
Pedro said: "We have treated seven patients in the past year, all with success and without complications. Unfortunately a significant proportion of candidates for these procedures are in desperate situations with failing hearts and after all drugs have failed before they reach us. Hopefully, with greater awareness of the availability of this procedure, we can treat more patients before it gets to be that bad."
Clive Elwood, Managing Director of Davies Veterinary Specialists said: "This is a great example of how our team of specialists can deliver ground-breaking and innovative care, which makes a real difference for both patients and their loving owners."
