Educational Pearls:

  • Common symptoms for congestive heart failure (CHF) are dyspnea, lower extremity edema, and chest congestion. Right heart failure usually presents with JVD and pedal edema. Left heart failure usually presents with chest congestion with rales and rhonchi.
  • A crescendo and decrescendo murmur on presentation indicates congestive heart failure due to aortic stenosis.
  • Common treatment for aortic stenosis causing congestive heart failure is lasix and some ace-inhibitor (not necessarily done in an emergency room) to manage symptoms, but this condition will require a surgical aortic valve replacement.
  • Normally it is within reason to give a nitroglycerin paste, but in a patient with critical aortic stenosis this can cause cardiovascular collapse.
