Differential Factors for Predicting Outcomes in Left Main versus Non-Left Main Coronary Bifurcation Stenting.

ABSTRACT:

Background

No large-scale study has compared the clinical and angiographic predictors of cardiovascular events in patients with left main bifurcation (LMB) and non-LMB stenting after second-generation DES implantation. Herein, we investigated differential clinical and angiographic factors for predicting outcomes in LMB versus non-LMB stenting.

Methods

A total of 2648 patients with bifurcation lesions treated with second-generation DESs from the retrospective patient cohort were divided into an LMB group (n = 935) and a non-LMB group (n = 1713). The primary outcome was the 7-year incidence of target lesion failure (TLF), defined as the composite of cardiac death, myocardial infarction, and target lesion revascularization.

Results

The incidence of TLF was 9.8%. Those in the LMB group were associated with a higher risk of TLF (14.2% versus 7.5%, p < 0.001) than those in the non-LMB group. Regarding the LMB group, independent predictors of TLF were chronic kidney disease (CKD), reduced left ventricular ejection fraction (LVEF), and two-stenting. Regarding the non-LMB group, CKD, reduced LVEF, old age, diabetes, and small diameter of the main vessel stent were independent predictors of TLF.

Conclusions

The two-stent strategy could potentially increase TLF for the LMB lesions, and achieving the maximal diameter of the main vessel stent could result in better clinical outcomes for non-LMB lesions.

Validation of bifurcation DEFINITION criteria and comparison of stenting strategies in true left main bifurcation lesions.

Project description:There are controversies on optimal stenting strategy regarding true left main (LM) bifurcation lesions. The present study compared 1- and 2-stenting strategy for patients with true LM bifurcation lesions as differentiated by DEFINITION criteria. 928 patients with true LM bifurcation lesions (Medina 1,1,1 or 0,1,1) treated with DES were enrolled consecutively. 297 (32.0%) patients were identified as complex LM bifurcation, and 631 (68.0%) patients into simple LM bifurcation group according to DEFINTION criteria. Patients in complex vs. simple LM bifurcation group had significantly higher major adverse cardiac event (MACE, including cardiac death, myocardial infarction [MI] and ischemia-driven target vessel revascularization) rate at 30 days (7.8% vs. 4.0%, p = 0.01), 1 year (10.3% vs. 6.4%, p = 0.04), and numerically at 3 years (14.2% vs. 10.1%, p = 0.07), which was mainly driven by increased MI. Moreover, patients in the 2-stent strategy group had strong trend towards lower incidence of cardiac death in both complex LM bifurcation group (2.0% vs. 5.9%, p = 0.08) and simple LM bifurcation group (1.9% vs. 4.5%, p = 0.07). In conclusion, the complex bifurcation lesion criteria established in DEFINITION study was able to risk-stratify LM bifurcation patients. Two-stent technique yielded numerically lower 3-year cardiac mortality regardless of LM bifurcation complexity.

Predictors and 3-year outcomes of compromised left circumflex coronary artery after left main crossover stenting.

Project description:BackgroundThere are few predictors of decreased fractional flow reserve (FFR) in the left circumflex coronary artery (LCx) after left main (LM) crossover stenting.ObjectivesWe aimed to determine the predictors for low FFR at LCx and possible treatment strategies for compromised LCx, together with their long-term outcomes.MethodsAltogether, 563 patients who met the inclusion criteria were admitted to our hospital from February 2015 to November 2020 with significant distal LM bifurcation lesions. They underwent single-stent crossover percutaneous coronary intervention (PCI) under intravascular ultrasound (IVUS) guidance with further LCx intervention based on the measured FFR.ResultsThe patients showed significant angiographic LCx ostial affection post-LM stenting, but only 116 (20.6%) patients had FFR < 0.8. The three-year composite major adverse cardiac events (MACE) rates were comparable between the high and low FFR groups (16.8% vs. 15.5; p = 0.744). In a multivariate analysis, low FFR at the LCx was associated with post-stenting minimal luminal area (MLA) of LCx (odds ratio [OR]: 0.032, p < .001), post-stenting LCx plaque burden (OR: 1.166, p < .001), poststenting LM MLA (OR: 0.821, p = .038), and prestenting LCx MLA (OR: 0.371, p = .044). In the low FFR group, those with compromised LCx managed with drug-eluting balloon had the lowest three-year MACE rate (8.1%), as compared to either those undergoing kissing balloon inflation (KBI) (17.5%) or stenting (20.5%) (p = 0.299).ConclusionUnnecessary LCx interventions can be avoided with FFR-guided LCx intervention. Poststenting MLA and plaque burden of the LCx, and main vessel stent length are poststenting predictors of low FFR.

Effect of Stenting Strategy on the Outcome in Patients with Non-Left Main Bifurcation Lesions.

Project description:Previous studies have not compared outcomes between different percutaneous coronary intervention (PCI) strategies and lesion locations in non-left main (LM) bifurcation lesions. We enrolled 2044 patients from a multicenter registry with an LAD bifurcation lesion (n = 1551) or non-LAD bifurcation lesion (n = 493). The primary outcome was target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization (TLR). During a median follow-up period of 38 months, non-LAD bifurcation lesions treated with the two-stent strategy, compared with the one-stent strategy, were associated with more frequent TLF (20.7% vs. 6.3%, p < 0.01), TLR (16.7% vs. 4.7%, p < 0.01), and target vessel revascularization (TVR; 18.2% vs. 6.3%, p < 0.01). There was no significant difference in outcome among LAD bifurcation lesions treated with different PCI strategies. The two-stent strategy was associated with a higher risk of TLF (adjusted HR 4.34, CI 1.93-9.76, p < 0.01), TLR (adjusted HR 4.30, CI 1.64-11.27, p < 0.01), and TVR (adjusted HR 5.07, CI 1.69-9.74, p < 0.01) in the non-LAD bifurcation lesions. The planned one-stent strategy is preferable to the two-stent strategy for the treatment of non-LAD bifurcation lesions.

Primary percutaneous coronary intervention for a left main bifurcation lesion without stenting using excimer laser with optical coherence tomography guidance: a case report.

Project description:Background:Optimal strategy for treating bifurcation lesions or lesions with large thrombus in left main disease remains elusive. Excimer laser coronary angioplasty (ELCA) is a therapeutic option for thrombotic lesions in acute coronary syndrome. Case summary:A 68-year-old man with chest pain was transferred to our emergency department, and subsequently diagnosed as inferior ST-segment elevation myocardial infarction (STEMI). Emergent coronary angiography revealed a 75% stenosis in the left main trunk (LMT). Optical coherence tomography (OCT) showed massive thrombus at the distal LMT to the ostial left anterior descending artery (LAD) and left circumflex artery (LCx). ELCA was performed in the three directions from LMT to proximal LAD, proximal LCx, and obtuse marginal branch. OCT after ELCA showed reduction of thrombus and no apparent plaque rupture or calcification, implying that coronary thrombosis was caused by OCT-defined plaque erosion. Intracoronary electrocardiogram of the LCx showed ST-segment elevation which corresponded to inferior ST-segment elevation, whereas no intracoronary electrocardiogram ST-segment elevation was detected for LAD. Taking all of the data including angiographic appearance, OCT-derived residual lumen size and residual thrombus volume, and strategic options into consideration, we completed percutaneous coronary intervention without stent deployment. He has been free from any cardiac events thereafter for 8?months. Discussion:Optimal strategy of coronary intervention for bifurcation lesions, especially LMT bifurcations, remains elusive. ELCA may have a potential to safely reduce intracoronary thrombus in patients presenting with acute coronary syndrome with OCT guidance.

Randomized non-inferiority TrIal comParing reverse T And Protrusion versus double-kissing and crush Stenting for the treatment of complex left main bifurcation lesions.

Project description:BackgroundThe treatment of left main bifurcation stenoses remains challenging.AimsWe compare the "Reverse T and Protrusion" (reverse-TAP) technique to Double-Kissing and crush (DK-crush).MethodsThe study was designed as non-inferiority trial, the primary endpoint was percentage stent expansion in the ostial side branch at optical coherence tomography.Results52 consecutive patients (13 females, 17 diabetics, Syntax score 25 [22-29]) with complex coronary bifurcation lesions of the left main were randomized in a 1:1 ratio to Reverse-TAP or DK-crush stenting. The intervention was performed according to protocol in all patients in both randomization groups. Side branch stent expansion was 75 [67-90]% in the DK-crush group and 86 [75-95]% in the reverse-TAP group (one-sided 97.5% lower parametric confidence interval: - 0.28%; P < 0.01 for non-inferiority; P = 0.037 for superiority). Side branch balloon pressure during final kissing was higher in the DK-crush group (14 [12-16] vs. reverse-TAP: 13 [12-14]; P = 0.043). Procedural time was shorter with reverse-TAP (DK-crush: 32 [24-44] min vs reverse-TAP: 25 [22-33] min; P = 0.044). Other procedural parameters were not different between groups. There was no difference in any of the safety endpoints up to 1 month.ConclusionsA reverse-TAP strategy for the interventional treatment of complex coronary lesions was non-inferior and superior to DK-crush for the primary endpoint side branch expansion while requiring less time. A larger study testing long-term clinical outcomes is warranted.Trail registrationNCT: NCT03714750.

Left main-like bifurcation primary percutaneous coronary intervention case report: anomalous right coronary artery ostium from the left anterior descending.

Project description:BackgroundA single coronary artery ostium (SCAO) is estimated to be present in 0.066% of the general population. The proximal coronary course and the relationship with surrounding structures are related to malignant vs. benign prognoses. We present a case of SCAO with the right coronary artery (RCA) arising from the mid-left anterior descending (LAD), complicated by anterior and inferior STEMI because of acute thrombotic occlusion at the bifurcation and its percutaneous management.Case summaryA 56-year-old male was admitted with sudden onset of resting chest pain. His ECG showed an anterior, inferior, and right ventricular STEMI. Via trans-radial access, coronary angiography showed significant stenoses at the left main and the circumflex but also a thrombotic occlusion at the proximal segment of the LAD while no RCA was seen. After crossing the LAD occlusion, the dominant RCA appeared from the mid-LAD. A provisional stent technique was performed achieving good results. Coronary computed tomography angiography showed an SCAO congenital anomaly with a patent stent in the bifurcation accompanied by diffuse coronary artery disease causing mild stenosis of the left main, proximal, and distal circumflex.DiscussionThe RCA arising from the mid-LAD with pre-pulmonic course has been described in only 37 cases. One reported an LAD/RCA bifurcation treatment with two stents technique in a stable scenario. The present is the first case reported of an acute thrombotic occlusion of an LAD/RCA bifurcation clinically resulting in a left main equivalent STEMI treated successfully with primary percutaneous coronary intervention using a bifurcation technique.

Real-Life Outcomes of Coronary Bifurcation Stenting in Acute Myocardial Infarction (Zabrze-Opole Registry).

Project description:Percutaneous coronary intervention (PCI) of bifurcation lesions is a technical challenge associated with high risk of adverse events, especially in primary PCI. The aim of the study is to analyze long-term outcomes after PCI for coronary bifurcation in acute myocardial infarction (AMI). The outcome was defined as the rate of major adverse cardiac event related to target lesion failure (MACE-TLF) (death-TLF, nonfatal myocardial infarction-TLF and target lesion revascularization (TLR)) and the rate of stent thrombosis (ST). From 306 patients enrolled to the registry, 113 were diagnosed with AMI. In the long term, AMI was not a risk factor for MACE-TLF. The risk of MACE-TLF was dependent on the culprit lesion, especially in the right coronary artery (RCA) and side branch (SB) with a diameter >3 mm. When PCI was performed in the SB, the inflation pressure in SB remained the single risk factor of poor prognosis. The rate of cumulative ST driven by late ST in AMI was dependent on the inflation pressure in the main branch (MB). In conclusion, PCI of bifurcation culprit lesions should be performed carefully in case of RCA and large SB diameter and attention should be paid to high inflation pressure in the SB. On the contrary, the lower the inflation pressure in the MB, the higher the risk of ST.

Trans-radial versus trans-femoral intervention for the treatment of coronary bifurcations: results from Coronary Bifurcation Stenting Registry.

Project description:Trans-radial (TR) approach is increasingly recognized as an alternative to the routine use of trans-femoral (TF) approach. However, there are limited data comparing the outcomes of these two approaches for the treatment of coronary bifurcation lesions. We evaluated outcomes of TR and TF percutaneous coronary interventions (PCI) in this complex lesion. Procedural outcomes and clinical events were compared in 1,668 patients who underwent PCI for non-left main bifurcation lesions, according to the vascular approach, either TR (n = 503) or TF (n = 1,165). The primary outcome was major adverse cardiac events (MACE), including cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR) in all patients and in 424 propensity-score matched pairs of patients. There were no significant differences between TR and TF approaches for procedural success in the main vessel (99.6% vs 98.6%, P = 0.08) and side branches (62.6% vs 66.7%, P = 0.11). Over a mean follow-up of 22 months, cardiac death or MI (1.8% vs 2.2%, P = 0.45), TLR (4.0% vs 5.2%, P = 0.22), and MACE (5.2% vs 7.0%, P = 0.11) did not significantly differ between TR and TF groups, respectively. These results were consistent after propensity score-matched analysis. In conclusion, TR PCI is a feasible alternative approach to conventional TF approaches for bifurcation PCI (clinicaltrials.gov number: NCT00851526).
