Cardiology Facts 45


  • Severe HTN, pulmonary edema - IV nitroglycerin
  • Coarctation of aorta is most common associated congenital cardiovascular abnormality with Turner syndrome 
  • Protein losing enteropathy, thromboembolic events, intra-atrial reentrant tachycardia are complications seen after atriopulmonary Fontan procedure for tricuspid atresia 
  • Carvedilol is beta blocker with alpha-blocking activity 
  • AVR, progressive dyspnea on exertion for several weeks, TEE 0.8 cm or smaller echodensity (clot) - subacute mechanical prosthetic valve thrombosis, management low-dose fibrinolytic therapy
  • MI, HF (bibasilar crackles), EF 40% or less, mineralocorticoid receptor antagonists eg eplerenone 25mg daily reduce mortality risk
  • Coarctation of aorta occurs predominantly in males 
  • Myxomatous mitral valve disease, remote endocarditis - antibiotics recommended prior to dental cleaning 
  • Tenecteplase is most fibrin-specific  
  • ATP binding cassette transporter 1 (ABCA1) and ABCG1 both facilitate free cholesterol efflux to more mature HDL
