  • holosystolic
  • RB heave
  • FTT, tachypnea, diaphoresis with feed

A
  • PFO
  • thrombosis, migraine

  • ASD
  • fixed wide split S2
  • RV heave
  • grade 1-3

132
Q

AVSD cant hear in neonates but when older an S2 pulmonary sound resonates. EKG may show left axis deviation. Surgery urgency depends on acuity of situation.

A
  • ASVD
  • incomplete fusion of embryonic endocardial cushions, varying degrees of AV valves abnormality
  • murmur often inaudible in neonates
  • loud pulmonary component of S2
  • surgery
133
Q

COA. you’re gonna have a bad day when your femoral pulses go away. 20mm mercury upper over lower. systolic murmur sounds like a leaf blower. Listen at the back or left armpit. Girls with Turner’s are a known culprit. Boys are 3x more affected. PGE2 helps keep blood flow connected but surgery is the ultimate intervention. Heart failure in the first month might be your first hunch.

A
  • COA
  • absence of femoral pulses
  • UE BP 20mm hg higher than LE
  • boys 3x more than girls
  • girls with Turners
  • PGE2 infusion to keep patent until surgery
  • leading cause of HF in first month
134
Q

Tet is a bet you’re going to the Operating room. hypoxemia and cyanosis seem like certain doom. systolic ejection at left sternal border. dyspnea on exertion is certainly in order. chronic desat causes clubbing of digits, elevation of RBCs, hgb, hematocrit.

A
  • four defects: VSD, PS, misplaced aorta, RV hypertrophy.
  • hypoxemia, cyanosis, DOE, clubbing of fingers/toes, elevated RBCs, H&H
  • 2 dimensional imaging needed
