Patiens with advanced CAD frequently have recurrent Angina. Surgical and interventional options for these patients typically have been exhausted or will result in only partial revascularization. ESMR offers new hope for these patients and provides therapy which complement existing treatment procedures.
The number of patients with persistent Angina despite PCI is increasing due to improvement in revascularization procedures. Between 15-25% of patients undergoing revascularization procedures will not be free from angina one year after the procedure. Therapy to these patients is invasive or mostly used on medication. Patient medical history of interventions determine the risk to have repeated angina.
The more interventions the patient had the higher the chance to have angina again.
It is also the treatment indicated for patients who no longer benefit from current revascularization method due to –
1.Large number of occluded small arteries ( 2.Occlusions in a small artery (< 2.5 mm) that cannot be treated with Anti Angina medication, CABG or Angioplasty
3.Chronic Total Occlusion (CTO) in one major coronary artery
So in these cases ESMR may be an option.
Other cardiac indications:-
- Chronic Heart failure
- Post MI (Remodeling)
- Post PCI / Post CABG(Reperfusion Injury)
- Post PCI (Persistent ST Elevation)
- Silent ischemia/ Hybernating myocardium
