      Jenifer,

      Welcome to the group, but sorry you had to join. You will find a
      wealth of information and experience here, they are a great source of
      support.

      The LVOT, as people have mentioned, is the left ventricular outflow
      tract - that is the path that the blood takes when it leaves the left
      side of the heart and enters the aorta. The dynamic obstruction,
      refers to the partial blocking of this pathway caused by the movement
      of the heart as it beats (hence the dynamic). Tavy may also have SAM
      of the mitral valve, which is systolic anterior motion of the valve
      between the upper and lower chambers of the left side of the heart,
      basically a backwards bulging of the mitral valve. It is commonly
      seen with severe LVOT obstruction. All of this is caused by the
      enlargement of the left side of the heart, the hypertrophy. Atenolol
      may reduce this enlargement and increased exercise tolerance is
      sometimes noted even in our asymptomatic cats.

      Heart murmur grades refer to the difficulty taken in hearing the
      murmur. A grade one requires careful listening in a quiet room with
      a stethescope while a grade 6 can be heard standing close the the
      patient - this is often seen in patients with mechanical heart
      valves. Tavy's atenolol may improve her murmur if the flow through
      her mitral valve decreases leaking.

      good luck and keep us updated,
