Coronary bifurcation lesions are commonly encountered, and side branch compromise is a major complication of these bifurcation interventions. Jailing a wire in the side branch is the most common method of significant side branch protection. Jailing a balloon in the side branch is a less well known and seldom practiced strategy of side branch preservation but tends to have lower occlusion rates as compared to conventional jailed wires. Various modifications have been applied to the original jailed balloon technique to further improve side branch patency. Complications arising from this technique have been limited to case reports only and relate mainly to calcified vessels.

A 72‐year‐old man with prior history of coronary artery bypass grafting and sternal wire infection presented with non‐ST‐segment elevation myocardial infarction. His coronary angiogram revealed stenosis of the distal left main coronary artery (LMCA) and a pseudoaneurysm of saphenous venous graft (SVG) to right posterior descending artery. Patient developed ventricular fibrillation during admission, and postcardiopulmonary resuscitation, a pulsatile chest mass was observed which was diagnosed with computed tomography as a chest wall collection resulting from rupture of the pseudo‐aneurysm. He underwent percutaneous coronary intervention of the LMCA with drug‐eluting stents followed by successful coil embolization of the SVG pseudoaneurysm. Patient had an uneventful recovery postprocedure.

Objectives: To retrospectively review the short term outcomes of rotational atherectomy in a high CathPCI Risk and high Syntax Population. Methodology: A total of 51 patients who underwent RA between 1st June 2017 and 31st April 2019 were retrospectively reviewed after approval from ethical review committee. Clinical follow up was obtained for procedural success and major adverse cardiovascular events (MACE) at 3 months. Results: Patients who underwent RA were high risk with a mean Syntax score 32.7±5.9 and mean NCDR CathPCI risk score of 51.1±13. The mean age of the patients were 70 years, majority were males (81%), type 2 diabetics (78%) with chronic kidney disease (52.7%), Non-ST elevated myocardial infarction (NSTEMI) (35%) and Syntax Score>32 (64.8%). Out of 37 individuals, procedural success was reported in all subjects except one in the high risk syntax group. At three months, MACE was reported in 4 patients. Out of these four, one was intra-procedural death, three had repeat myocardial infarction. Out of these three, two declined repeat revascularization and were managed medically. One patient died during admission despite repeat revascularization. Almost all MACE reported, occurred in patients with Syntax>32. Conclusion: Despite high risk Syntax and CathPCI scores, RA led to high immediate procedural success for PCI in calcified lesions at our hospital with infrequent MACE.
