Cardiology Facts 46

 

  • Recurrent left leg DVT - May Thurner syndrome 
  • Most preterm infants with birth weight less than 1500 g have PDA 
  • Active, asymptomatic, carotid artery ultrasound 100% right occlusion and <70% left occlusion - intensive medical therapy with annual screening for progression (because of contralateral carotid artery occlusion, peak systolic velocity measured by ultrasound in left carotid artery is falsely elevated due to collateral flow, leading to overestimation of the stenosis severity) 
  • LMS equivalent with low EF - treatment CABG 
  • Diastolic MR on echo is typical of acute aortic regurgitation 
  • Troponin I levels peak 12-24 hours 
  • Murmur since childhood, increased intensity S2,  systolic ejection murmur heard best in first right intercostal space radiating to neck and increases with expiration, thrill in suprasternal notch. Left carotid and brachial pulses diminished - diagnosis supravalvular AS, Williams syndrome 
  • PAD, LDL 70 mg/dL, LFTs mild elevation - high intensity statin indicated eg atorvastatin 40 mg daily to achieve 50% LDL reduction  
  • In HCM, elevated LVOT gradient is not indication for ICD 
  • Clopidogrel and ticlopidine are ADP inhibitor
