In this video, Dr. Viveka Kumar, Senior Director - Cath Lab, Max Super Speciality Hospital, Saket, will talk on late restenosis after primary PCI. Late restenosis is a possibility and annual attrition rate of 0.1 % patients can get restenosis even after 10 years. This problem can be tackled by drug eluting balloons or stents can be managed. These patients are followed annually by stress test or stress-echo or stress thallium to check for restenosis. If it shows positive, then repeat angiogram is done.
