    This is the best explanation of dilated cardiomyopathy I could ever imagine. You are a fantastic doctor, and even a better teacher! 🙏🏼🙏🏼🙏🏼

    The book Essential Echocardiography by Scott Salomon gives ischemia and hypertension as one of the causes of Dilated Cardiomyopathy. If it's a disease of a heart muscle why it can't be caused by ischemia or hypertension or valvular disease?

  • @MeganMichelleTimeLapses

    my textbook says a cause of dilated cardiomyopathy is ischemic heart disease and valvular disease

    This video has information contradictory to other sources I've seen, i.e. the video posted by "Osmosis". In the latter, reduced contractility is seen as a result of dilation of the heart's chambers (dilation = decreased CO); in your video, reduced contractility is seen as the cause of the dilation of the heart's chambers (decreased CO = dilation). Your explanation makes sense; dilation is initially a compensatory mechanism to decreased ejection fraction, which ends up eventually leading to a further decreased ejection fraction; a paradox (decreased CO = dilation = decreased CO). However, this explanation sounds an awful lot like systolic heart failure. What is the difference between diastolic cardiomyopathy and systolic heart failure?
    Additionally, your video claims that dilated cardiomyopathy is not caused by ischemic/valvular heart disease or hypertension, whereas the video by "Osmosis" and my textbook both claim that dilated cardiomyopathy can be a cause of secondary cardiomyopathy. Perhaps, your intention was to address primary cardiomyopathy, in which case, risk factors would be appropriate to include, rather than causes.

    If I have the hereditary type of DCM, will it show on echocardiogram at any age? Does the condition itself develop slowly/later in life or is it just the symptoms that show after some time?

  • @positivevibes7425

    A chronic pressure overload on the left ventricle due to aortic stenosis results in: A) left ventricular dialatation B) decrease contractility c) altered left ventricular distensibility. kindly reply

  • @LadyJesterSurfer

    Thank you very much. I was trying to understand DCM, because it's a genetic disorder in a large percentage of Doberman. This helped a lot.

    so..what we should write on echo report:dilated cardiomyopathy secondary to hypertension or ischemia etc.>> or we just mention that only dilated ventricles

      elle est secondaire a l augmentation du volume télédiastolique ☺

    • @mehdi-zi9oo
      @mehdi-zi9oo 4 ปีที่แล้ว

      @@solainekabily5989 pour reprendre la physiopathologie simplement:
      Dilatation Ventriculaire + baisse Inotropisme
      >>
      baisse FE + augmentation du VTS
      >>
      baisse de la Vidange auriculaire et
      augmentation des Pressions auriculaires gauches
      résultat = augmention de la PTDVG
      la CMD n'est donc pas secondaire à l'augmentation de PTD mais au dysfonctionnement systolique dont il faut déterminer l'étiologie.
      (nb: la vidéo ne mentionne pas que l'atteinte est à gauche dans la grande majorité des cas)
      bon courage pour la suite

    Is it possible to have dilated cardiomyopathy but the EF is around 50-55? And also diagnosed with LVF, systolic and diastolic dysfunction? How do you diagnose odema on the abdomen? Is diastolic dysfunction not normal during aging? Is it poss to have cardiomegaly but not cardomyopathy? Is it poss to have cardiomyopathy but normal ECG? How is heart failure then diagnosed? What should the patient look out on an echo that shows heart failure and DCM? Also why is the BNP sometimes normal, other times higher? Thank you.
