– 1 year, 3 month old Dutch Shephard presented with a grade 3-4 systolic murmur, not clinical for heart disease and just spayed with no anesthetic concerns

– echo shows SAS with a fibrous ridge at the entrance of the LVOT, aortic widening, AI and MR

– the LV walls and chamber normal in diastole, no LAE (so compensated) – mitral valves look normal

– Aortic Max Velocity 3.6 m/s (PG 52.1 mmHG) (could not get a subcostal view due to patient’s tensing)

Some questions:

1. I can not find a consistent reference on how to grade this SAS (all over the map!) – mild? mild-moderate? moderate?

2. When should a repeat echo, if any, be recommended?

3. Are antibiotics currently in vogue to be given before dental procedures due to increased risk of endocarditis?
