??ALPACA: Anomalous Left Coronary Artery from the Pulmonary Artery. What’s that?
??Coronary artery, instead of originating from the aorta, arises from the pulmonary artery.
??In Fetal Life when pulmonary vascular pressures are high, there is flow from the pulmonary artery to the myocardium.
??After birth, when pulmonary vascular resistance?decreases, blood is “stolen” from the myocardium and flows retrograde to the pulmonary artery.
??In adult Life Collateral blood vessels can help compensate for diminished myocardial perfusion.
??Even with collateral perfusion, myocardial damage still occurs.
* LV scarring and diminished LV function
* Leads to:
* Myocardial ischemia
* Left ventricular dysfunction
* Mitral insufficiency
* Congestive heart failure
* Arrhythmias
* Sudden Death
??Do u know other causes of stolen coronary artery blood flow?
