Three-dimensional optical coherence tomography versus intravascular ultrasound in percutaneous coronary intervention for the left main coronary artery. Heart Vessels 2021; 36:630-637. [PMID: 33389063 DOI: 10.1007/s00380-020-01742-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 11/27/2020] [Indexed: 10/22/2022]
Abstract
We aimed to compare the intravascular imaging findings, and clinical outcomes between three-dimensional optical coherence tomography (OCT)- and intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for the left main coronary artery (LMCA). We enrolled 331 patients underwent OCT- or IVUS-guide single crossover stenting across the side branch (SB) and subsequent kissing balloon inflation (KBT) for LMCA bifurcation. Primary endpoint was defined as a composite of cardiac death, myocardial infarction, and target lesion revascularization. Of 331 patients, 58 patients (17.5%) underwent OCT-guide PCI. OCT-guide PCI associated with higher frequency of proximal optimization technique (POT) (98.3% vs 85.3%, P = 0.013) and smaller balloon size of POT (4.29 ± 0.44 mm vs 4.43 ± 0.42, P = 0.02) than IVUS-guide PCI. Although maximal stent area at LMCA and minimal stent area at main vessel were significantly smaller in OCT-guide PCI in intravascular imaging (P = 0.01, and P = 0.002, respectively), the restenosis rate at follow-up angiography was comparable in both groups (15.2% vs. 9.4%, P = 0.387). Cumulative rate of primary endpoint was not significantly different between 2 groups both before and after propensity score adjustment (7.0% vs. 7.4%, P = 0.98 and 2.6% vs. 7.3%, P = 0.18). In conclusion, the clinical outcomes at 1 year were comparable, suggesting OCT- and IVUS-guided PCI for LMCA were similarly feasible. The balloon size of POT in OCT-guide PCI might be influenced by the limited visibility in the proximal LMCA.

Abstract
The appropriate stent platform for treating coronary bifurcation lesions (CBLs) remains controversial. Previous bench tests have demonstrated the superiority of a 2-link cell design to 3-link cell design for creating inter-strut dilation at the side branch ostium. This randomized multicenter prospective BEGIN trial compared the biodegradable polymer-based biolimus A9-eluting stent (2-link BES) with the durable polymer-based cobalt chromium everolimus-eluting stent (3-link EES) in 226 patients with de novo CBLs. Patients with true bifurcations, defined as > 50% stenosis in the main vessel and side branch (SB) and an SB diameter > 2.25 mm, were enrolled. Guide wire re-crossing to the distal cell (near the carina) in the jailed SB and final kissing inflation were recommended. The SB angiographic endpoint was < 50% stenosis diameter. Left-main CBLs (13.5% vs. 13.0%) and 2-stent technique (30.6% vs. 22.6%) rates were similar. The primary endpoints (minimum lumen diameter at the SB ostium measured at an independent core laboratory at the 8-month follow-up) were comparable (1.64 ± 0.50 mm vs. 1.63 ± 0.51 mm, p = 0.976). There was no significant difference in composite outcomes of cardiac death, myocardial infarction, or target vascular revascularization at 12 months (7.4% vs. 8.0%, p = 0.894). Two-link BES and 3-link EES showed similar 8-month angiographic and 1-year clinical outcomes for true CBLs.

Abstract
OCT requires intracoronary injection of contrast agent to remove blood from the coronary lumen during data acquisition, which is a possible limitation of this method. Aim of this study was to analyze the influence of iodine concentration on image quality and diagnostic certainty of optical coherence tomography (OCT). OCT sequences acquired using contrast agent with a reduced concentration of 150 mg iodine/ml and a standard concentration of 350 mg iodine/ml were analyzed. Cross-sectional images with a spacing of 10 mm were evaluated regarding image quality and diagnostic confidence. A total of 67 OCT sequences acquired in 24 patients were analyzed. 31 sequences were acquired using contrast agent with a concentration of 150 mg iodine/ml and 36 sequences with a concentration of 350 mg iodine/ml. The percentage of remaining blood streaks in the cross sections was significantly lower for 350 mg iodine/ml compared to 150 mg iodine/ml (19 ± 21 vs. 34 ± 26%, p = 0.013). Contrast with 350 mg iodine/ml showed a significantly higher percentage of completely flushed pullback length as compared to 150 mg iodine/ml (78 ± 24 vs. 58 ± 27%, p = 0.004). Diagnostic certainty was significantly higher for 350 mg iodine/ml than for 150 mg iodine/ml (Likert scale average 1.4 ± 0.7 vs. 2.1 ± 1.2, p < 0.001; Likert scale: 1 = absolutely confident, 2 = confident with slight doubts, 3 = doubtful/not confident, 4 = non-diagnostic). Regarding image quality and diagnostic certainty, contrast agent with a concentration of 350 mg iodine/ml is superior to 150 mg iodine/ml.
