Four-year outcomes of unprotected left main lesion treated with one-stent versus two-stent technique

Introduction – Most reports on left main bifurcation lesions have demonstrated that treatment with a singlestent strategy is superior to a two-stent strategy but have excluded patients with acute coronary syndromes (ACS). Aims – The aim of the current study was to compare the four year outcomes of patients with unprotected left main coronary artery disease (ULMCAD) treated by percutaneous coronary intervention (PCI) with a one-stent or two-stent strategies in a population including those presenting as ACS. Methods – A total of 135 patients with ULMCAD treated by PCI were included, of which 75 (55.6%) had a one-stent strategy (Group A) and 60 (44.4%) had a two-stent strategy (Group B). Results – Fewer patients in Group A had a TIMI III flow at the end of the procedure (89.4% vs 100%, p=0.03) and complete revascularization (65.3% vs 88.3%, p=0.002). We found a higher early mortality in Group A without reaching statistical significance (13.4% vs 3.3%, p=0.1). Mortality rate at 4-year follow up was higher with Group A after multivariable analysis (adjusted HR 0.36, CI 0.15-0.85, p=0.02). We found no significant differences between the groups in terms of major adverse cardiac event (MACE) (adjusted HR 0.85, CI 0.34-1.48, p=0.7) or target lesion revascularization (TLR) (adjusted HR 1.37, CI 0.42-4.47, p=0.6) at 4-year follow up. Conclusions – Among unselected patients with ULMCAD PCI, with or without ACS, the early mortality rate is similar between one and two-stent strategy. Although, 4 year TLR and MACE rates were similar between the two groups, the 4-year all-cause mortality rate was lower in the two-stent strategy group.

Abstract Background: Percutaneous coronary intervention (PCI) of left main coronary artery disease (LMD) is associated with appropriate clinical and angiographic outcomes, resulting in a class I recommendation in patients with less complex coronary anatomy. Due to higher SYNTAX scores and worse clinical outcomes, PCI in distal LMD is accomplished with a lower strength of recommendations for revascularization compared to ostial LM lesions. We compare angiographic and clinical outcomes of ostial/midshaft lesions versus distal lesion in LMD after PCI. Methods: This retrospective study included 176 patients with LMD undergoing PCI with drug-eluting stents. The study population was divided into 34 patients with ostial/midshaft LMD and 142 patients with distal LMD. Patients were routinely scheduled for 9 months of angiographic and 12 months of clinical follow-up. Quantitative coronary analysis (QCA) was performed for all lesions, using an 11-segment model. Primary outcome was MACE (major adverse cardiac events) defined as a composite of cardiac death, myocardial infarction and target lesion revascularization (TLR). Results: The primary outcome measure was comparable in both cohorts after 12 months follow-up (20.6% in ostial/midshaft LMD vs. 17.6% in distal LMD, P=0.71). As expected, TLR rates were increased in distal LM lesions compared to ostial LM lesions, but without reaching statistical significance (14.1% vs. 5.9%, P=0.15). Late lumen loss (LLL) in ostial/midshaft LMD was 0.42±0.33mm. In distal LM lesions value for LLL in the main vessel was 0.42±0.97 mm, with the highest values observed in segments adjacent to the bifurcation (0.37±1.13mm and 0.37±0.73 mm). On cox proportional regression analysis LLL in a bifurcation segment (P=0.03, HR 1.68 [1.1-2.7]) and diabetes mellitus (P=0.046, HR 2.77 [1.0-7.5] were independent correlates for occurrence of MACE. Conclusion: PCI of distal LM lesions result in comparable angiographic and clinical outcomes compared to ostial LM lesions. Highest rates for binary restenosis were observed in segments nearest to the bifurcation.

Abstract Introduction Conservative treatment unprotected left main coronary (uLMCA) disease has a high mortality rate (50% at 3 years). Since octogenarian patients are often dismissed for surgical treatment, they tend to adopt a more conservative attitude in this population. Purpose We report medium and long-term outcomes of percutaneous coronary intervention (PCI) for uLCMA stenosis in elderly patients. Methods Retrospective cohort study of consecutive patients ≥80 years with uLMCA stenosis, treated with PCI at a single center between June 2005 and February 2017. Results A total of 100 patients were included in the study. 58% were male, with a mean age of 83.8±3 years. There were 86% hypertensive, 63% diabetic and 68% dyslipidemic. 14% of the patients had an LVEF ≤35%. Unstable angina (45%) and acute coronary syndromes withouth ST-segment elevation (44%) were the most common presentation. In 9% of the cases, cardiogenic shock was the initial presentation form. The distal left main coronary was the most frequent localitation of the lesion (46%) followed by the ostium (33%). In 63% of the cases, a multivessel coronary disease was detected and in 47% the revascularization was incomplete. The survival rate after a year follow up was 79% and after three years follow up was 65%. However, in most of the cases the cause of death was due to other comorbidities, with cardiac death being 10% per year and 13% at 3 years of follow-up. The rate of non-fatal acute myocardial infarction was 13% per year, increasing to 20% at 3 years of follow-up. There was a 9% stent restenosis implanted at 3 years. The presence of severe left ventricular systolic dysfunction was the main predictor of mortality in long-term follow-up (OR 1.39 [95% CI 1.10–1.752], p<0.001). Incomplete revascularization was not associated with a higher mortality rate. Conclusion PCI is a safety option for revascularization in uLMCA stenosis in elderly patientes with excellent short-term results, as well as acceptable long-term results. Age should not be a handicap to consider uLMCA revascularization in this population.

Objective: To identify risk factors for pediatric mechanical mitral valve replacement (mMVR) to improve management in this challenging population. Methods: From 1993 to 2019, 93 children underwent 119 mMVR operations (median age, 8.8 years [interquartile range [IQR]: 2.1-13.3], 54.6% females) at our institution. Twenty-six (21.8%) patients underwent mMVR at ≤2 years and 93 (78.2%) patients underwent mMVR at >2 years. Median follow-up duration was 7.6 years [IQR: 3.2-12.4]. Results: Early mortality was 9.7%, but decreased with time and was 0% in the most recent era (13.9% from 1993 to 2000, 7.3% from 2001 to 2010, 0% from 2011 to 2019, P = .04). It was higher in patients ≤2 years compared to patients >2 years (26.9% vs 2.2%, P < .01). On multivariable analysis for mitral valve reoperation, valve size <23 mm was significant with a hazard ratio of 5.38 (4.87-19.47, P = .01);. Perioperative stroke occurred in 1% and permanent pacemaker was necessary in 12%. Freedom from mitral valve reoperation was higher in patients >2 years and those with a prosthesis ≥23 mm. Median time to reoperation was 7 years (IQR: 4.5-9.1) in patients >2 years and 3.5 years (IQR: 0.6-7.1) in patients ≤2 years ( P = .0511), but was similar between prosthesis sizes ( P = .6). During follow-up period (median 7.6 years [IQR: 3.2-12.4], stroke occurred in 10%, prosthetic valve thrombosis requiring reoperation in 4%, endocarditis in 3%, and bleeding in 1%. Conclusion: Early and late outcomes of mMVR in children are improved when performed at age >2 years and with prosthesis size ≥23 mm. These factors should be considered in the timing of mMVR.

Abstract We present the case of patient with ST elevation myocardial infarction in cardiogenic shock with primary percutaneous coronary intervention of Left anterior descending coronary artery and Left main coronary artery with staged complex procedure on Left anterior descending/Diagonal branch bifurcation in Culotte manner. Th is case shows that “the simpler, the better” approach of only infarct related artery revascularization may be applied in acute patients with cardiogenic shock and optimal clinical and hemodynamic response on revascularization and intra-aortic balloon pump. But, complete revascularization should be done in staged procedure and later, a control coronary angiography with intravascular ultrasound assistance is mandatory.

Background: Very little data exists regarding percutaneous coronary intervention (PCI) as an alternative to coronary artery bypass graft (CABG) for the treatment of unprotected left main disease (LMD) in octogenarians, and no studies to date have compared CABG and PCI for the treatment of LMD in this population. The objectives of our study were to compare the acute and midterm follow-up results of PCI and CABG for the treatment of significant LMD in octogenarians. Methods: A total of 163 consecutive patients ≥80 years old diagnosed with LMD have undergone coronary revascularization in our center between 2002 and 2006. One hundred and one patients underwent CABG and 62 patients had PCI (non-surgical candidates: 30%, very high surgical risk patients: 61%, patient refusal of CABG: 9%). All complications occurring within the first 30 days following the procedure were recorded, and major adverse cardiovascular events -MACCE- (cardiac death, myocardial infarction, cerebrovascular event, revascularization) were evaluated at follow-up. Results: Patients who underwent PCI were older (85 ± 3 yrs vs. 82 ± 2 yrs, p<0.0001), presented more frequently with an acute coronary syndrome (92% vs. 50%, p<0.0001), and had a higher EuroSCORE (9.5 ± 2.7 vs. 8.5 ± 2.5, p=0.01). Drug-eluting stents were used in 48% of PCI patients. There were no significant differences in the incidence of MACCE at 30 days between groups (CABG: 28%, PCI: 19%, p=0.22), but the CABG group was associated with a higher rate of atrial fibrillation (48% vs. 14%, p<0.0001) and acute renal failure (17% vs. 6%, p=0.05). The incidence of MACCE occurring between 30 days and 24 ± 17 months follow-up was higher in the PCI group (32% vs. 13%, p=0.005), but the cumulative incidence of MACCE was similar in both groups (CABG 39% vs. PCI 44%, p=0.53). Conclusions: PCI was associated with a 30-day cardiac event rate similar to that of CABG for the treatment of unprotected LMD in octogenarians. Surgical patients experienced fewer cardiac events during the follow-up period, but the cardiovascular event-free survival rate was similar between groups at 2-year follow-up. Further randomized studies with longer-term follow-up comparing both revascularization strategies in this high risk coronary population are warranted.

The Impact

Objectives. The aim of this study was to assess the clinical impact of 3 bifurcation angles in left main (LM) bifurcation treated with the 2-stent technique. Background. Data are limited regarding the impact of bifurcation angles after LM percutaneous coronary intervention (PCI). Methods. Using patient-level 4 multicenter registries in Korea, 462 patients undergoing LM bifurcation PCI with the 2-stent technique were identified (181 crush, 167 T-stenting; 63% 1st generation drug-eluting stent (DES), 37% 2nd generation DES). Three bifurcation angles, between the LM and left anterior descending (LAD), the LM and left circumflex (LCX), and the LAD and LCX, were measured. The primary outcome was target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization (TLR). Results. In patients treated with the crush technique, the best cutoff value (BCV) to predict TLF was 152° of the LM-LAD angle. In the crush group, a significantly higher TLF rate, mostly driven by TLR, was observed in the LM-LAD angle ≥152° group compared with the <152° group (35.7% vs. 14.6%; adjusted hazard ratio 3.476; 95% confidence interval 1.612–7.492). An LM-LAD angle ≥152° was an independent predictor of TLF. In the T-stenting, no bifurcation angle affected the clinical outcomes. Conclusions. In LM bifurcation PCI using the 2-stent technique, wide LM-LAD angle (≥152°) was associated with a greater risk of TLF in the crush, whereas none of the bifurcation angles affected T-stenting outcomes.

Abstract Introduction Percutaneous coronary intervention (PCI) in patients with left main (LM) coronary artery disease is acquiring an important role in the last years as an alternative to coronary artery bypass grafting (CABG) in selected patients. The objective of the study was to evaluate predictors of mortality in patients with LM coronary artery disease treated with PCI. Methods Prospective and observational study of consecutive patients referred to our centre for coronary angiography, with LM coronary artery disease, whom PCI was decided in a “Heart team” as a strategy for revascularization between July 2015 and December 2017. Baseline clinical, analytical and coronary angiography data were collected. Follow-up was conducted in person or by telephone for a minimum of one year. We analysed the predictive variables of mortality by means of an uni and multivariate logistic regression model. In addition, a survival analysis was performed. Results A total of 191 patients were recruited. The average age was 72 years (±11.4), 79% males. 42% had previous documented coronary artery disease. PCI was performed in the context of acute coronary syndrome in 81% of them. The mean follow-up period was 17.9 months (± 8.3). After multivariate analysis, the following variables remained as independent predictors of mortality: the hemodynamic situation of the patient, assessed by the Killip-Kimball scale (OR 1.58, 95% CI 1.03–2.43; p=0.04) and the presence of peripheral arterial disease (PAD) (OR 2.61, 95% CI 1.03–6.67; p=0.04) (table 1). The ROC curve of the multivariate model showed an AUC of 0.796 (figure 1A). In the survival analysis, patients with PAD had a significantly lower survival, with a median survival of 6 months, compared to 13.9 months in those without PAD, with p=0.008 (figure 1B). Uni and multivariate analysis Univariate analysis Multivariate analysis OR (95% CI) p OR (95% CI) p Killip-Kimbal scale 1.94 (1.39–2.72) 0 1.58 (1.03–2.43) 0.04 LVEF 0.96 (0.93–0.99) 0.01 0.99 (0.95–1.03) 0.46 Mitral regurgitation 2.54 (1.12–5.63) 0.02 1.60 (0.55–4.56) 0.38 Number of affected vessels 1.96 (1.24–3.29) 0.01 1.78 (1.03–3.37) 0.05 PAD 2.54 (1.16–5.49) 0.02 2.61 (1.03–6.67) 0.,04 Figure 1 Conclusion Although PCI revascularization of LM coronary artery disease is an attractive alternative to CABG in selected patients, a word of caution should be raised in patients with PAD, as in the present study this variable was an important predictor of short-medium term mortality.

Objectives To compare the effectiveness and safety of the Braidin® slender 7 Fr sheath with a standard 6 Fr sheath for treating left main bifurcation disease. Methods From January 2017 to March 2019, 277 patients with left main bifurcation disease who underwent the transradial approach for percutaneous coronary intervention were divided into the slender 7 Fr sheath group (Braidin® slender 7 Fr sheath, n = 154) and standard 6 Fr sheath group (n = 123). Pathological features, surgical effect, and complications were evaluated. Results The rate of using the classic crush technique was significantly higher in the slender 7 Fr sheath group than in the standard 6 Fr sheath group. The slender 7 Fr sheath group had a significantly shorter operation time than the standard 6 Fr sheath group. There were no significant differences in the radial artery occlusion rate after surgery and at 1 month of follow-up between the groups. Multivariate logistic regression analysis showed that 6 Fr and Braidin slender 7 Fr sheaths did not predict radial artery occlusion. Conclusion The Braidin slender 7 Fr sheath has a superior operative process and similar safety for the radial artery as that of the standard 6 Fr sheath for treating left main bifurcation disease.
