  • Bilateral leg edema, hyperpigmentation of ankles, ulcer above medial malleolus - chronic venous insufficiency 
  • Asymptomatic AS with normal LVEF & no change in signs or symptoms, aortic velocity is 2.0-2.9 m/sec - TTE for reevaluation 3-5 years 
  • In complete d TGA & complete AVCD interatrial communication is almost always present 
  • In congestive heart failure digoxin reduces hospitalization
