    Hey!

    I will try and get some images together next week to post – sometimes only really obvious if there is dilation but medium sized dogs they’re easier to see. I’ll see what I can do.

    The cardiac cycle is super important to understand to help interpret echo and pathology so I’m fully supportive of you digging deeper. Isovolumic contraction time occurs at the start of systole when the mitral and aortic valves are both shut but the ventricles are starting to contract. As they contract they squeeze the ventricular chamber which increases pressure quickly. Then, there is a point at which the pressure in the ventricle exceeds aortic and pulmonic pressure and the valves open. Blood is ejected and that is the end of IVCT (the start of blood being ejected). It might be obvious but if you have mitral regurgitation you don’t have an IVCT period. As soon as the ventricle contracts you get leak of blood across the MV into the LA. Therefore the volume held in the ventricle changes. When there are no leaks the volume stays the same and only the pressure increases.

    Hope that makes sense!

    Hi Scott

    This is interesting and a paper I wasn’t aware of. I don’t think I have too much to add other than what’s in the discussion. It’s rarely documented in people and is a new finding in cats. The cause is unknown but we do know that animals and people in heart failure have systemic inflammatory markers and changes to clotting etc so it’s probably linked to this. Further research required!

    Hi,

    Lovely to have you join me on this new course and I hope you find it useful 🙂

    I have replied to your email just now, but for others here is what I said 🙂

    So I have a vivid and you can change the settings and calculations to a veterinary one without too much issue. I really like the GE and Philips machines. I have used Easote and they also have quite good image quality (not as good as GE or Philips) but they are very nice to use too. I’ve also use Sonoscape and they are cheaper machines but produce nice images. I think they would struggle though with larger dogs and the Doppler isn’t as good as the Easote.

    I think, if you’ve the money to spend, trialing some of the above would be your best bet. It’s alot about personal preference as well as the probes. You’d be best spending more on the probes and slightly less on the machine sometimes too!

    Hope that is a bit helpful 🙂

    Hi Sarah

    Yes, that’s quite a tricky one. Generally though you want to ensure that you don’t volume load them too much so cautious with the fluids, even though you might have a stage B1 cat you could still induce CHF with over judicious use of fluids. You can give medetomidine to cats with HCM, lower doses, as they have diastolic dysfunction not systolic dysfunction it is safer to use and they don’t mind a slight increase in afterload. Usually though, opioids and alfaxalone induction with inhalational is going to be fine. More fractious cats you can use low dose alpha-2. I don’t know doses off the top of my head I’m afraid as I always defer to our anaesthesia colleagues!

    Hope that is somewhat helpful

    Hi both,

    I would agree with Scott’s comments above. The only time I’d consider performing this procedure is in a dyspnoeic dog and then the owners have to be aware that coughing will continue. I was working with Scott last year and he was referred a case for stent placement and when the dog walked through the door I think Scott and I were both thinking it would be a great candidate. However, the dog did very well on medical management and never (this far at least) required a stent.

    The dogs that we have performed stents in don’t have further dyspnoeic episodes and the coughing can be relatively well managed with medications. At the time off stent placement we will scope and BAL them to make sure we haven’t got any infectious component to the cough. We tend to try and do everything under one GA (scope, BAL and stent) as recovery is risky in these patients if work up is done in a staged approach.

    Hi all,

    Welcome to this fab course, covering a wide range of topics.

    I am Liz Bode, one of the Directors of vtx but I am also a Specialist in Cardiology working out of Chestergates Veterinary Specialists near Chester in the UK. I also have two small boys, 2 and 4 years old who keep me busy and very entertained!

    I look forward to working with you all over the next few weeks and I will ‘see’ you for coughing and the ECG lesson at the end of the course. We really hope you enjoy it and it gives you more confidence in your every day clinical practice.

    Any questions, please ask as always.

    Liz

    Massive thanks to you all. We hope you enjoyed the course and learnt things that you can take in to your every day practice. I’m going to post an ECG for your thoughts over the course of the next couple of weeks too, so feel free to have a look at that and let me know what you think 🙂

    Hi Maria,

    This is a good question. We do need to be more cautious in cats with steroids generally. There is a link (or possible link) between giving a cat steroids and them developing heart failure. A study on healthy cats a few years ago found that a dose of steroids caused significant changes in glucose levels and vascular volume in some cats, not all, studied. We think that in cats with heart disease these fluid shifts can then precipitate heart failure as cats with HCM and diastolic dysfunction are less able to cope with fluid changes and can develop heart failure as a result. Some people, however, question whether it is the steroids that cause heart failure or whether it is the stress of going to the vets in the first place!

    However, until we can better define the risk I would always be cautious giving a cat steroids without certain clinical need (like acute asthma episode), especially if they have signs of heart disease such as a murmur, gallop sound or arrhythmia. We don’t worry in dogs as they tolerate steroids and changes in vascular volume better as their underlying heart diseases don’t tend to cause diastolic dysfunction.

    Hope that makes sense!

    Hi all

    Just to finish this case;

    We performed a thoracic POCUS and there were diffuse B-lines together with a dilated RA and RV with very prominent PA. Therefore we treated Millie for pulmonary hypertension, put her in oxygen and left her alone for 24 hours with monitoring only. She responded very well and we were able to take her out of oxygen 48hours later – a miracle! A CT showed changes consistent with fibrosis and echo moderate PHT. The acute onset didn’t quite fit this picture and my differentials were PTE or non-cardiogenic pulmonary oedema. She is currently on sildenafil, clopidogrel and had a course of fenbendazole too. She’s doing well!!

    Hi all,

    I have just noticed a mistake in the date for this event. It is actually tomorrow 30th July at 8pm. The link above should work and the papers are the same.

    See you then,

    Hi,

    Great question and always a tricky one. I think if the cat is a stage B2 and is asymptomatic then it is best to go ahead with the dental procedure. You will need to be very cautious with any fluids you give, if any, and monitor blood pressure closely. That being said these cats will manage with even a low dose of medetomidine. I’d probably use methadone if the cat is calm as a pre-med then induce with alfaxalone and maintain with whatever gas you use. You could also perform nerve blocks if confident with those which will help with analgesia but also reduce the amount of anaesthetic you use.
    Hope that is useful?
