Stent delivery within a tortuous and/or calcified vessel after rotational or laser atherectomy. (D) The final angiographic result with thrombolysis in myocardial infarction grade III flow. (C) The GL was then deeply intubated to permit distal lesion predilatation and stent delivery (Tsunami ® 3 ×15 mm and 3.5 ×10 mm ). Proximal balloon dilatation was required in order to deliver the GL (Vascular Solutions, MN, USA) distally as the proximal lesion was obstructive. Balloon delivery failure was encountered due to marked vessel calcification and tortuosity particularly at the mid vessel U-bend. (B) The right coronary artery was engaged transfemorally with an Amplatz 0.75 GC (Boston Scientific, MA, USA) and the lesion crossed with a PT Graphix(TM) Wire (Boston Scientific). (A) Heavily calcified and tortuous right coronary artery that was occluded distally. Deep vessel intubation to facilitate distal balloon and stent delivery in an 85-year-old male on peritoneal dialysis undergoing primary percutaneous coronary intervention for an ST-elevation myocardial infarction. (E) It was successfully delivered and deployed in the circumflex artery. (D) The stent (3.5 ×16 mm Promus Element(TM) ) was advanced through the metal collar of the GL. (C) Deep vessel intubation and effective backup support was achieved by delivering the GL catheter into the vessel over a balloon shaft, thus negating the effect of the proximal tortuosity. Following predilatation, stent delivery failure was encountered due to severe tortuousity.

(B) The circumflex artery was engaged with an Extra backup 3.5 GC (Medtronic, MN, USA) and the calcified lesion was crossed using a Balance Middleweight(TM) Wire (Abbott Laboratories, IL, USA) and the support of a 2.0 ×12 mm balloon. (A) Subtotally occluded calcific proximal circumflex artery in a markedly tortuous vessel.
