Thank you Nadia (my co-fellow to be next year!!) for presenting an amazing cardiology case with Anne Thorson. She presented the case of a man w/ hx of crack cocaine use and recent strep pneumo meningitis p/w acute SOB found to have a diastolic murmur, PR prolongation, sinus exit block and an perivalvular abscess!! The patient was found to have severe chronic AI and was being evaluated by CT surgery for definitive management while on IV abx. Keep us updated!!
- ECG conduction changes, from first degree AV block to complete heart block, are associated with increased mortality in patients with known endocarditis (Am Heart J 2001;142:280-5.)
- See this study in the American Heart Journal for more information about conduction abnormalities and endocarditis (remember that these will occur at the level of AV node).
- See Figure below for more information on sinus exit block.
