a b s t r a c t We describe a case of an 84-year old gentleman undergoing PCI of a heavily calcified and stenotic right coronary artery. Rotational atherectomy was employed, but due to difficulties in wiring and burr advancement, extra deep guide-catheter intubation was used to provide support and facilitate advancement of the burr and subsequent stent deployment. An approach with careful extra deep guide-catheter intubation in rotablation is an option that might be considered for selected cases with severely stenotic, calcified, angulated lesions. © 2019 Elsevier Inc.

1. Case report An 84-year old gentleman was referred for percutaneous coronary intervention (PCI) of the right coronary artery (RCA) due to stable angina CCS III, despite optimal medical treatment. He had extensive inferior wall ischemia by dobutamine stress echocardiography. His coronary angiography had disclosed multiple severely calcified and stenotic lesions at the distal RCA (Fig. 1A – Video 1). An attempt for PCI in another hospital was unsuccessful, because no balloon (not even 1.25 mm) would cross the stenosis. A new attempt was performed transfemorally with adjuvant use of rotational atherectomy (Rotablator; Boston Scientific, Massachusetts, USA). A temporary pacing wire was inserted and a 6-French Judkins Right 4 (JR4) guide-catheter cannulated the RCA ostium. Using a Finecross (Terumo, Japan) microcatheter, a hydrophilic angioplasty wire crossed the stenosis and was exchanged for Rotawire (Boston Scientific). Consequently, however, the 1.25 mm Rotaburr (Boston Scientific) could only be advanced to mid RCA. Then, with a pushing and clockwise maneuver, we gently advanced the JR4 guide-catheter over the Rotaburr catheter (as a “railway”), very deep into the RCA, while monitoring the pressure waveform for signs of damping or ventricularization and avoiding contrast injection (Fig. 1B – Video 2). The patient remained angina-free without ECG changes or hemodynamic compromise, despite continuous deep engagement, and the

pressure waveform remained stable. Rotational atherectomy could then be performed with 1.25 mm and 1.5 mm burrs, and predilatation with 2.0 mm and 2.5 mm non-compliant balloons at high pressures followed. Three drug-eluting stents 2.5 × 26 mm, 2.5 × 30 mm and 3.0 × 34 mm (Resolute Integrity; Medtronic, Santa Rosa, CA, USA) were subsequently implanted with overlap from distally to proximally; the two distal with deep guide-catheter engagement and the proximal after slight guide catheter withdrawal. The final angiographic result was excellent (Fig. 1C–D – Videos 3–4). 2. Discussion We describe a case where extra deep guide-catheter intubation was used to advance the Rotaburr. Deep catheter intubation has been suggested to increase catheter backup in challenging cases with tortuous arteries [1–3]. However, implementation of this technique has not been reported thus far for rotational atherectomy. Although several alternatives could be applied, we dismissed them. Specifically, since a 7 French or an Amplatz Left guide-catheter that might have increased passive guide support had not been used from the beginning, performing at this stage an exchange for such a catheter with complete system removal would have turned into a starting-again scenario, in an already very difficult to wire stenosis. The use of guide-catheter extension catheters has been used in very few selected cases [4], but the catheter would have to be advanced over the slim 0.009″ Rotawire and would hardly accommodate just the 1.25 mm burr. We opted therefore for the careful extra deep guide-catheter intubation to facilitate the Rotaburr advancement, while cautiously observing pressure waveform and avoiding contrast injection which could possibly cause a hydraulic

An approach with careful extra deep guide-catheter intubation in rotablation is an acceptable option for selected cases with severely stenotic, calcified, angulated lesions of the RCA.
