Left Main Stem Percutaneous Coronary Intervention - Data and Ongoing Trials.

ABSTRACT: Left main stem (LMS) disease is associated with significant morbidity and mortality. Traditionally coronary artery bypass grafting (CABG) has been the gold standard for treatment of these lesions. However over the past decade, percutaneous coronary intervention (PCI) has assumed a more prominent role in the treatment of LMS disease. With the advent of newer drug-eluting stents (DES) with an improved risk factor profile, better intravascular imaging modalities and careful patient selection, the use of PCI in this cohort is expanding. We review the current data to support this and discuss the on-going trials that will hopefully shed more light into the management of this complex disease.

Adoption of same day discharge following elective left main stem percutaneous coronary intervention.

Project description:BackgroundThis study sought to investigate the safety and feasibility of same day discharge (SDD) practice and compare clinical outcomes to patients admitted for overnight stay (ON) undergoing elective left main stem (LMS) percutaneous coronary intervention (PCI). ON observation is still widely practiced in highly complex PCI as the standard of care, with no previous data comparing clinical outcomes in patients undergoing LMS PCI.MethodsWe analysed 6452 patients undergoing elective LMS PCI between 2007 and 2014 in England and Wales. Multiple logistic regressions and the BCIS risk model were used to study association between SDD and 30 day mortality.ResultsSDD rates almost doubled from 19.9% in 2007 to 39.8% in 2014 for all LMS procedures and increased from 20.7% to 41.4% for unprotected LMS cases during the same study period. There was a significant increase in procedural complexity with higher use of rotational atherectomy, longer stents and multivessel PCI. SDD was not associated with increased 30 day mortality (OR 0.70 95%CI 0.30-1.65) in the overall LMS PCI cohort and the results were similar in unprotected LMS (OR 0.48 95%CI 0.17-1.41) and those requiring ON stay (OR 0.58 95%CI 0.25-1.34).ConclusionsWe did not find evidence that SDD is not safe or feasible in highly complex LMS PCI procedures despite increasing procedural complexity with no significant increase in 30 day mortality rates.

Percutaneous coronary intervention for left main stem disease: Impact of diabetes mellitus on mortality.

Project description:ObjectivesWe assessed the impact of diabetes mellitus (DM) on mortality after percutaneous coronary intervention (PCI) for left main stem (LMS) disease. Second, we compared mortality outcomes between non-insulin treated (NITDM) and insulin treated diabetes (ITDM) in different clinical settings.BackgroundThere is a paucity of "real world" outcomes data in diabetic patients undergoing LMS PCI.MethodsWe undertook a retrospective analysis of consecutive patients undergoing unprotected LMS PCI at 2 high volume tertiary centers. Diabetic status and clinical setting for PCI were recorded. The primary outcome measure was all-cause 30-day and long-term mortality (up to 36 months) post index PCI.ResultsBetween 2003 and 2017, 2,675 patients undergoing index LMS PCI were analyzed. Of those, 77.1% were non-DM, 15.8% NITDM, and 7.1% ITDM. Overall, DM status was not associated with higher 30-day mortality (OR 1.39, 95% CI 0.89-2.16, p = .15). During a median follow-up of 36 months, there was a borderline statistical association of DM with long-term mortality in all PCI settings (HR 1.31, 95% CI 1.00-1.71, p = .05). Compared to non-DM, ITDM but not NITDM was associated with short- and long-term mortality in all clinical presentations.ConclusionsOverall, DM did not impact on 30-day mortality and had only a borderline statistical association with long-term mortality. It did not have an influence on mortality in non-emergency LMS PCI. The impact of DM on mortality outcomes following LMS PCI was only significant in the insulin treated patients.

Unprotected left main revascularization: Percutaneous coronary intervention versus coronary artery bypass. An updated systematic review and meta-analysis of randomised controlled trials.

Project description:BackgroundThe optimal treatment of unprotected left main (UPLM) with either PCI or CABG remains uncertain.AimThe purpose of this study was to determine the comparative safety and efficacy of PCI versus CABG in patients with UPLM disease.MethodsSearch of BioMedCentral, CENTRAL, mRCT, PubMed, major cardiological congresses proceedings and references cross-check (updated November 2016). Outcomes were the rate of MACE [all cause death, MI, stroke], the rates of the individual components of MACE and the rate of target vessel revascularisation (TVR).ResultsWe identified 6 Randomised Controlled Trials totalling 4717 patients allocated to PCI or CABG. At 1 year follow up, PCI and CABG were substantially equivalent with respect to the rates of MACE [PCI 8.5% vs CABG 8.9%, OR 1.02,(0.76-1.36), p = 0.9], death [PCI 5.4% vs CABG 6.6%, OR 0.81,(0.63-1.03),p = 0.08] and MI [PCI 3.4% vs CABG 4.3%, OR 0.80(0.59-1.07), p = 0.14]. Notably, PCI was associated with a significantly lower rate of stroke [PCI 0.6% vs CABG 1.8%, OR 0.36,(0.17-0.79), p = 0.01] and with a significantly higher rate of TVR [PCI 8.7% vs CABG 4.5%, OR 2.00(1.46-2.75), p<0.01]. At a median follow up of 5years, the rates of MACE were similar between the two strategies: PCI 14.6% vs CABG 13.8%, OR 1.02(0.76-1.38), p = 0.89. Likewise, the rates of death [PCI 8% and CABG 7.7%, OR 1(0.77-1.31), P = 0.9], MI [PCI 6.1% vs CABG 5%, OR 1.41(0.85-2.34), P = 0.19, I2 59%], and stroke [PCI 2% vs CABG 2.2%, OR 0.85(0.42-1.81), p = 0.65,] were similar while PCI was associated with a significantly higher rate of TVR [14.5% vs CABG 8.9%, OR 1.73(1.41-2.13), p<0.01].ConclusionIn patients with UPLM disease, PCI and CABG are associated with similar rates of MACE and mortality at 1 year as well as after 5 years. Differences can be detected for individual end points at both short and long term FU.

Emergency percutaneous coronary intervention for left main trunk thrombus following orthotopic heart transplantation.

Project description:Heart transplantation (HTx) is the gold standard therapy to improve quality and quantity of life in end-stage heart failure patients. However, recipients are at risk of experiencing allograft rejection and post-transplant complications, in the acute as well as chronic phase. A 43-year-old man with a history of left ventricular non-compaction underwent orthotopic HTx. On Day 7, transthoracic echocardiography showed a sudden decrease in cardiac function with hypokinesis in a left ventricular anterior wall distribution. Coronary angiography revealed a large thrombus in the left main trunk. With intra-aortic balloon pump support, emergency percutaneous coronary intervention was performed. Endomyocardial biopsy showed no rejection. A left main trunk thrombus is rare in the early phase after HTx, but it can be a life-threatening complication. Transthoracic echocardiography is well known to be important in the management of heart transplant recipients, and coronary angiography as well as myocardial biopsy should be considered when left ventricular wall motion is impaired.

Percutaneous coronary intervention vs. coronary artery bypass grafting for left main revascularization: an updated meta-analysis.

Project description:AimsThe optimal revascularization strategy for left main coronary artery disease (LMD) remains controversial, especially with two recent randomized controlled trials showing conflicting results. We sought to address this controversy with our analysis.Methods and resultsComprehensive literature search was performed. We compared percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for LMD revascularization using standard meta-analytic techniques. A 21% higher risk of long-term major adverse cardiac and cerebrovascular event [MACCE; composite of death, myocardial infarction (MI), stroke, and repeat revascularization] was observed in patients undergoing PCI in comparison with CABG [risk ratio (RR) 1.21, 95% confidence interval (CI) 1.05-1.40]. This risk was driven by higher rate of repeat revascularization in those undergoing PCI (RR 1.61, 95% CI 1.34-1.95). On the contrary, MACCE rates at 30 days were lower in PCI when compared with CABG (RR 0.55, 95% CI 0.39-0.76), which was driven by lower rates of stroke in the PCI arm (RR 0.41, 95% CI 0.17-0.98). At 1 year, lower stroke rates (RR 0.21, 95% CI 0.08-0.59) in the PCI arm were balanced by higher repeat revascularization rates in those undergoing PCI (RR 1.78, 95% CI 1.33-2.37), resulting in a clinical equipoise in MACCE rates between the two revascularization strategies. There was no difference in death or MI between PCI when compared with CABG at any time point.ConclusionOutcomes of CABG vs. PCI for LMD revascularization vary over time. Therefore, individualized decisions need to be made for LMD revascularization using the heart team approach.

Trends in Clinical Practice and Outcomes After Percutaneous Coronary Intervention of Unprotected Left Main Coronary Artery.

Project description:Background The use of percutaneous coronary intervention (PCI) to treat unprotected left main coronary artery disease has expanded rapidly in the past decade. We aimed to describe nationwide trends in clinical practice and outcomes after PCI for left main coronary artery disease. Methods and Results Patients (n=4085) enrolled in the SCAAR (Swedish Coronary Angiography and Angioplasty Registry) as undergoing PCI for left main coronary artery disease from 2005 to 2017 were included. A count regression model was used to analyze time-related differences in procedural characteristics. The 3-year major adverse cardiovascular and cerebrovascular event rate defined as death, myocardial infarction, stroke, and repeat revascularization was calculated with the Kaplan-Meier estimator and Cox proportional hazard model. The number of annual PCI procedures grew from 121 in 2005 to 589 in 2017 (389%). The increase was greater for men (479%) and individuals with diabetes (500%). Periprocedural complications occurred in 7.9%, decreasing from 10% to 6% during the study period. A major adverse cardiovascular and cerebrovascular event occurred in 35.7% of patients, falling from 45.6% to 23.9% (hazard ratio, 0.56; 95% CI, 0.41-0.78; P=0.001). Radial artery access rose from 21.5% to 74.2% and intracoronary diagnostic procedures from 14.0% to 53.3%. Use of bare-metal stents and first-generation drug-eluting stents fell from 19.0% and 71.9%, respectively, to 0, with use of new-generation drug-eluting stents increasing to 95.2%. Conclusions Recent changes in clinical practice relating to PCI for left main coronary artery disease are characterized by a 4-fold rise in procedures conducted, increased use of evidence-based adjunctive treatment strategies, intracoronary diagnostics, newer stents, and more favorable outcomes.

Delayed percutaneous coronary intervention for an extensive iatrogenic left main coronary artery dissection: a case report.

Project description:BackgroundIatrogenic left main coronary artery dissection is a rare but serious complication that can occur both during diagnostic coronary angiography and percutaneous coronary intervention. Early diagnosis and choice of optimal management are of crucial importance for patient's outcome while representing a challenge for clinicians.Case presentationWe present a case of iatrogenic left main coronary artery dissection occurring during diagnostic coronary angiography in a 53-year-old Greek woman with a history of coronary artery bypass grafting. Although dissection was greatly extending to mid left anterior descending artery, delayed percutaneous coronary intervention was successfully performed by carefully wiring the true lumen.ConclusionsDelayed percutaneous coronary intervention, performed 25 days following the index event, proved to be a feasible and effective strategy for treating a widely extended left main coronary artery iatrogenic dissection.

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.

Percutaneous coronary intervention in left main coronary artery disease with or without intravascular ultrasound: A meta-analysis.

Project description:This meta-analysis compared IVUS-guided with angiography-guided PCI to determine the effect of IVUS on the mortality in patients with LM CAD. Current guidelines recommend intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with left main coronary artery disease (LM CAD; Class IIa, level of evidence B). A systematic search of the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases was conducted to identify randomized or non-randomized studies comparing IVUS-guided PCI with angiography-guided PCI in LM CAD. Ten studies (9 non-randomized and 1 randomized) with 6,480 patients were included. The primary outcome was mortality including all-cause death and cardiac death. Compared with angiography-guide PCI, IVUS-guided PCI was associated with significantly lower risks of all-cause death (risk ratio [RR] 0.60, 95% confidence interval [CI] 0.47-0.75, p<0.001), cardiac death (RR 0.47, 95% CI 0.33-0.66, p<0.001), target lesion revascularization (RR 0.43, 95% CI 0.25-0.73, p = 0.002), and in-stent thrombosis (RR 0.28, 95% CI 0.12-0.67, p = 0.004). Subgroup analyses indicated the beneficial effect of IVUS-guide PCI was consistent across different types of studies (unadjusted non-randomized studies, propensity score-matched non-randomized studies, or randomized trial), study populations (Asian versus non-Asian), and lengths of follow-up (<3 years versus ?3 years). IVUS-guided PCI in LM CAD significantly reduced the risks of all-cause death by ~40% compared with conventional angiography-guided PCI. PROSPERO registration number: CRD 42017055134.

Percutaneous coronary intervention versus cardiac bypass surgery for left main coronary artery disease: A trial sequential analysis.

Project description:BackgroundSeveral updated meta-analyses comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) for left main coronary artery disease (LM CAD) have been published recently. However, the risk of false-positive results could be high in conventional updated meta-analyses due to repetitive testing of accumulating data. Therefore, we compared these treatment approaches via trial sequential analysis (TSA).MethodsThe MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for published randomized controlled trials (RCTs) or subgroups of RCTs comparing PCI and CABG in patients with LM CAD. The primary outcome was major cardiac and cerebrovascular adverse events (MACCE). TSA was used to confirm the conclusions derived from conventional meta-analysis.ResultsSix RCTs with 4700 patients were included. PCI was associated with a greater risk of MACCE compared with CABG (pooled relative risk [RR] 1.21, 95% confidence interval [CI]: 1.05-1.40, P?=?.008). In addition, PCI resulted in a significantly higher risk of revascularization than CABG (pooled RR 1.61, 95% CI: 1.33-1.95, P?<?.0001). TSA provided firm evidence for the reduction of MACCE and revascularization with CABG compared with PCI (cumulative z-curve crossed the monitoring boundary). In the subgroup analysis, CABG was better than PCI in patients with SYNTAX score >32 (pooled RR 1.41, 95% CI: 1.12-1.76, P?=?.003), which was confirmed by the TSA. There was no difference in patients with a SYNTAX score from 0 to 32.ConclusionsIn patients with LM CAD, CABG may be better than PCI for reducing MACCE due to a reduced risk of revascularization. CABG remains the first choice for LM CAD patients with high anatomic complexity, while PCI could be an alternative for those with low-to-moderate anatomic complexity.
