Hi doctor, My father had a major heart attack 15 days ago. The angiography report showed LAD/Diagonal - type III LAD. Mid has 90% stenosis. LCX/OM non-dominant. Early OM1 has 90% stenosis. OM2 has 80% stenosis. PTCA with DES to LAD has been performed. Now, what to do with OM1 and OM2? Please guide.
Hi. Any blockage of more than 70% if possible should be stented. In your father's case heart attack was due to mid LAD block (left anterior descending coronary artery) which has been treated. OM (obtuse marginal) branches supply papillary muscles and posterolateral wall of left ventricle, these are also significantly blocked but area supplied by them may have collaterals that we cannot say as collaterals are very tiny vessels. But, as he is on antiplatelet medicine now mostly he will not get sudden block of OMs. You can wait and see how he is feeling on walking and exertion. If no pain then ask your consultant for TMT (Treadmill test) and then decide for plasty. For further information consult a cardiologist online -->
