A 91-year-old woman presented with ST-segment elevation myocardial infarction (STEMI) after taking a meal. The emergent coronary angiography demonstrated acute proximal occlusion of the right coronary artery (RCA) (Figure 1 A). Initial aspiration thrombectomy (AT) with a Thrombuster II (Kaneka Medical) thrombus aspiration catheter (extraction area (EA) 0.95 mm2) recovered TIMI III flow. However, post-aspiration angiography demonstrated severe residual thrombus burden (Figure 1 B). Because of its large suction area, a guide extension mother-and-child catheter, Heartrail ST01 5 Fr (cross section area, CSA 1.77 mm2, Terumo Medical) catheter was positioned proximal to the site of the occlusion (Figure 1 C). Aspiration was performed with suction pressure generated by a 30 ml vacuum syringe and a larger and long embolus was sucked out (Figure 1 E), resulting in evident reduction of thrombus burden (Figure 1 D) and it was completed with a 3.5 × 30 mm zotarolimus-eluting stent (Endeavor, Medtronic) implantation. Histological examination showed thrombus with abundant infiltration of neutrophil (Figure 1 F). Furthermore, the patient received 100 mg of aspirin once daily and 90 mg of ticagrelor twice daily for 2 weeks, which was replaced by 100 mg of aspirin plus 75 mg of clopidogrel once daily with an 8-month follow-up to date and the patient has not suffered cardiovascular or bleeding events.
Despite improved clinical outcomes observed in early trials, recent randomized trials demonstrated that, in STEMI patients, as compared with percutaneous coronary intervention (PCI) alone, routine manual thrombectomy followed by primary PCI (PPCI) had no advantages in reduction of all-cause mortality, cardiovascular death, recurrent myocardial infarction, cardiogenic shock, or NYHA class IV heart failure but was associated with an increased rate of stroke [1]. Thus, routine thrombus aspiration is not recommended, but bailout in certain cases may be considered [2].
The success of manual aspiration is limited by multiple factors including catheter tip EA, vacuum generation, deliverability, and vessel and thrombus characteristics. A majority of PPCIs are performed through 6 Fr systems, and the greatest shortcoming is their small inner CSA (0.80 to 1.24 mm2). Moreover, utilizing 6 Fr guide systems markedly impeded the use of larger AT devices. Therefore, optimized AT with guide extension catheters seems to be a reasonable choice. In previous studies, guide extension catheters have been reported to have applications in facilitating equipment delivery, providing vessel support, thrombus aspiration, retrieval of lost devices, selective vessel contrast injection, and facilitation of chronic total occlusion lesion management [3]. Furthermore, various guide extension catheters, such as the same series Heartrail II-ST01 [4], GuideLiner V2 (EA 1.58 mm2, Vascular Solutions) and Guidezilla (EA 1.65 mm2, Boston Scientific), have been reported for AT, showing their outstanding efficacy in AT and safety for distal coronary embolization as well as stroke. The Heartrail ST01 catheter is a 120 cm straight tip 5 Fr with a CSA 1.77 mm2 resulting in an evidently larger aspiration force. It is the first time to apply the Heartrail ST01 to successfully extract such a large and long thrombus (approximate length = 56.8 mm, referring to the outer diameter of the filter) in the RCA, demonstrating the feasibility of utilization of the guide extension catheter for AT during PPCI with severe thrombus burden.
