Successful rotational atherectomy of left main stem with double kiss crush stenting using double guiding catheter: a case report

Abstract

Abstract Background Coronary artery bypass grafting is the preferred revascularization procedure for patients with multivessel disease, and those with complex left main disease, as it is associated with a survival advantage in this group of patients. Sometimes however surgical management is not the treatment of choice due to many factors including ongoing chest pain, haemodynamic instability, or patient preference. In these situations, percutaneous coronary intervention (PCI) offers an alternative revascularization strategy. In this case study, we present a successful PCI with rotational atherectomy (RA) for distal left main stem (LMS), left anterior descending (LAD), and circumflex artery (CX) using a double guide catheter technique in a patient with severe calcific disease. Case summary A 63-year-old female was diagnosed with a non-ST-elevation myocardial infarction. Coronary angiography showed significant distal LMS disease with a severe proximal/ostial calcified lesion of the LAD and a possible thrombotic lesion at the ostium of the CX. She had ongoing haemodynamic instability with chest pain however could not be offered immediate surgical revascularization. We therefore elected to proceed to complex bifurcation LMS coronary intervention using RA under intravascular ultrasound (IVUS) guidance achieving an excellent final result with TIMI III flow. Discussion This case demonstrates that RA using the double catheter technique (also known as Ping-Pong) can be safely performed with minimal complication rates and with very favourable angiographic and IVUS results. The clinical outcome was excellent with early discharge.
