ASDs- murmur
mid-systolic murmur in pulmonary area (similar to pulm stenosis)
fixed split S2 (delayed closure of pulm valve)
diastolic murmur at LLSB (tricuspid valve)
ASDs and typical age for closure
3-4
ASD closure in adults
Right sided heart dilation
symptoms of dyspnea
Qp:Qs >1.5:1
ASD differential
isolated anomalous pulmonary venous connection (looks identical on TTE)
Worrisome about ASD In adults??
paradoxical embolism
Risk of ASD, including when closed…
atrial fibrillation
VSD murmur
pansystolic over LLSB
can have mid diastolic rumble at apex (across mitral valve)
VSD size
related to AV area
small is 1/3, moderate 1/3 to 2/3, large is >2/3
Pulmonary Stenosis Murmur
SEM
Click (mild or moderate stenosis) at LLSB or LUSB, louder with exhalation
Diagnosis of Pericarditis (MKSAP)
2 of the following
- typical chest pain
- pericardial friction rub
- EKG findings
- pericardial effusion
Coarctation of Aorta - classic findings
HTN in upper extremities
radial to femoral artery delay

Chronic thromboemobolic pulm HTN
Pulm HTN Group 5
Multifactorial
Aortic Stenosis related bleeding diathesis
acquired von Willebrand syndrome
Further evaluation for patients with WPW
stress test
normalization of QRS indicates low risk for SCD
AE ticagrelor
dyspnea
P2Y12 Blockers in STEMI
PCI- ticagrelor (brilinta) or prasugrel (effient)
Fibrinolytics- clopidogrel
No intervention- ticagrelor
normal capillary wedge pressure
8-12 mmHg
Elevated JVP
3-4 cm above sternal angle
or 7-8 above RA
Hypoplastic Left Heart Syndrome - Features
underdeveloped left ventricle
underdeveloped aorta
PDA dependent
ASD
Hypoplastic Left Heart Syndrome - Procedures
Norwood –> Glenn –> Fontan
Norwood Procedure
1st procedure
Neoaorta from main pulmonary artery tissue
RV to PA conduit
Glenn Procedure
2nd procedure
anastomose SVC to pulm arterial system
take down conduit
Fontan Procedure
3rd procedure
connect IVC to pulm arterial system
Two continuous murmurs in pediatrics
PDA
venous hum
WPW- What are the TWO consequences
1) SVT
2) Sudden Cardiac Death
DAPT
6 months after drug-eluting stent
12 months after CABG
1 year after ACS
Normal Axis
Positive, upright in I and AvF
0-90
LAD
Positive in I, negative AvF
RAD
Negative in I, positive in AvF
Extreme RAD
Negative in I and Avf
Small and Large Blocks on EKG
.04 sec and .2 sec
Sinus rhythm
upright P wave in I, II and inverted in aVr
Positive QRS in I, II, AvF
TOF Repair
VSD Repair
Transannular patch to relieve pulmonary stenosis
TOF Murmur
harsh SEM over pulm area 2/2 pulmonary stenosis
Tet Spell- Physiology
increased pulmonary vascular resistance and increased HR
decrease ventricular filling and pulmonary flow
Tet Spell - Treatment
Increase SVR (knees to chest) oxygen IV bolus IV BB phenylephrine
Pulmonary Stenosis Murmur
SEM
Click (mild or moderate stenosis) at LLSB or LUSB, louder with exhalation
PDA Murmur
loud systolic (continuous machinery) at left precordium
Eisenmenger Syndrome
severe pulmonary HTN from reversal of shunt (now R to left)
LBBB
large S wave (rS) in V1
R in V6 (short bunny ears)
Mitral Regurgitation Murmur
- holosystolic at apex
- can be preceded by clicks (think MVP)
CHD associated with DiGeorge Syndrome
Truncus Arteriosus
precordial catch syndrome
short stabbing pains in chest
often with inspiration
possibly due to irritation of an intercostal nerve
Hypertrophic Cardiomyopathy- features/pathology
Left ventricular hypertrophy (with normal or small ventricle size)
Diastolic Dysfunction
Can Have
- LV outflow obstruction
- Systolic anterior motion of mitral valve
Hypertrophic Cardiomyopathy Murmur
systolic ejection murmur at LLSB or apex (think similar to aortic stenosis since its LVOT)
