- 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
