Cardiology Facts 14


  • Flecainide causes increase in digoxin level
  • Asymptomatic with good functional capacity, bicuspid aortic valve, AR 3 to 4+, normal EF with mildly dilated LV - vasodilator therapy
  • TEE is the most appropriate test at the time of or prior to PTMC
  • Peak oxygen consumption of less than 14mL/kg/minute in cardiopulmonary exercise testing in congestive heart failure identifies patients who would benefit from cardiac transplantation
  • Severe dyspnea, hypotension, tachycardia, hypoxia, apical systolic murmur, crackles, inferior Q waves, TTE mild MR - perform TEE for eccentric jet of papillary muscle rupture
  • Ischemic cardiomyopathy, worsening heart failure, AFib despite controlled ventricular rate - amiodarone for maintenance of sinus rhythm
  • Ectopia lentis is major criteria of Marfan syndrome
  • During perfusion stress testing, administration of adenosine or regadenoson does not provoke myocardial ischemia in patients with coronary artery disease
  • Atrial fibrillation lasting more than 48 hours or of uncertain duration require anticoagulation (dabigatran, rivaroxaban, apixaban, or edoxaban; or warfarin with a heparin bridge) after cardioversion independent of CHADSVaSC risk score
  • In HCM, systolic anterior motion of mitral valve is consistent with dynamic outflow tract obstruction
