RESUMO
BACKGROUND: The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial. METHODS: In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization. In this post-hoc analysis, the 3-year incidence of NODM was compared between rosuvastatin and atorvastatin treatment in the as-treated population with high-intensity statin therapy as the principal population of interest. RESULTS: Among 2932 patients without diabetes mellitus at baseline, 2377 were included in the as-treated population analysis. In the as-treated population with high-intensity statin therapy, the incidence of NODM was not significantly different between the rosuvastatin and atorvastatin groups (11.4% [106/948] versus 8.8% [73/856], hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.98 to 1.77, P = 0.071). When the risk of NODM with rosuvastatin versus atorvastatin was assessed according to the achieved low-density lipoprotein cholesterol (LDL-C) level, the risk of NODM began to increase at a LDL-C level below 70 mg/dL. The incidence of NODM was significantly greater in the rosuvastatin group than it was in the atorvastatin group when the achieved LDL-C level was < 70 mg/dL (13.9% versus 8.0%; HR = 1.79, 95% CI 1.18 to 2.73, P = 0.007). CONCLUSIONS: Among CAD patients receiving high-intensity statin therapy, the incidence of NODM was not significantly different between rosuvastatin and atorvastatin. However, a drug effect of the statin type on NODM was observed when the achieved LDL-C level was < 70 mg/dL. TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: NCT02579499.

OBJECTIVE: Endovascular aneurysm repair (EVAR) has been used worldwide to treat abdominal aortic aneurysms (AAAs). Outcomes after EVAR within and outside the instruction for use (IFU) remain controversial. We analyzed long-term outcomes of EVAR within-the-IFU compared with that outside-the-IFU and baseline clinical/anatomical characteristics that influence outcomes of EVAR. METHODS: The study included 546 patients who underwent EVAR for infrarenal AAA from 1997 to 2021 at 2 Korean medical centers. The primary endpoint was graft-related adverse events (GRAEs), including type 1 or 3 endoleak, reintervention (included open conversion), aneurysm sac enlargement, aneurysm-related mortality (ARM), rupture, stent-graft migration, and stent thrombotic occlusion. RESULTS: The patients who underwent EVAR outside the IFU were 287 (52.6%). A neck angle of >60° was most common outside the IFU criteria (n=146, 50.9%). This study revealed that patients outside the IFU had a higher rate of GRAEs compared with patients within the IFU (hazard ratio [HR]: 1.879; 95% confidence interval [CI]: 1.045-2.386). A neck angle of >60° was a significant risk factor for GRAEs (adjusted HR: 2.229; 95% CI: 1.418-3.503), type 1 or 3 endoleak (adjusted HR: 2.640; 95% CI: 1.343-5.189), and reintervention (adjusted HR: 1.891; 95% CI: 1.055-3.388). CONCLUSIONS: Our study revealed EVAR with outside the IFU was associated with increased GRAEs, mainly attributed to endoleak and ARM, compared with EVAR with within the IFU. In addition, severe neck angulation was an independent risk factor for GRAEs, type 1 or 3 endoleak, and reintervention. CLINICAL IMPACT: Our study revealed endovascular aneurysm repair (EVAR) with outside-the-instruction for use (IFU) was associated with increased graft-related adverse events (GRAEs) compared with EVAR with within-the-IFU. In the low-risk population, the incidence of GRAEs and Aneurysm related mortality were higher in the outside-the-IFU group rather than within-the-IFU group. In addition, severe neck angulation was an independent risk factor for GRAEs, type 1 or 3 endoleak and reintervention.
RESUMO
BACKGROUND: The optimal statin treatment strategy that is balanced for both efficacy and safety has not been clearly determined in older adults with coronary artery disease (CAD). METHODS: In the post hoc analysis of the LODESTAR (low-density lipoprotein cholesterol-targeting statin therapy versus intensity-based statin therapy in patients with coronary artery disease) trial, the impact between a treat-to-target strategy versus a high-intensity statin therapy strategy was compared in older adults (aged 75 years or older). The goal of treat-to-target low-density lipoprotein cholesterol (LDL-C) level was 50-70 mg/dl. The primary endpoint comprised the three-year composite of all-cause death, myocardial infarction, stroke or coronary revascularisation. RESULTS: Among 4,400 patients with CAD enrolled in the LODESTAR trial, 822 (18.7%) were aged 75 years or older. Poor clinical outcomes and risk factors for atherosclerosis were more frequently observed in older adults than in younger population (<75 years old). Among these older adults with CAD, the prescription rate of high-intensity statin was significantly lower in the treat-to-target strategy group throughout the study period (P < 0.001). The mean LDL-C level for three years was 65 ± 16 mg/dl in the treat-to-target strategy group and 64 ± 18 mg/dl in the high-intensity statin group (P = 0.34). The incidence of primary endpoint occurrence was 10.9% in the treat-to-target strategy group and 12.0% in the high-intensity statin group (hazard ratio 0.92, 95% confidence interval 0.61-1.38, P = 0.69). CONCLUSIONS: High-intensity statin therapy is theoretically more necessary in older adults because of worse clinical outcomes and greater number of risk factors for atherosclerosis. However, the primary endpoint occurrence with a treat-to-target strategy with an LDL-C goal of 50-70 mg/dl was comparable to that of high-intensity statin therapy and reduced utilisation of a high-intensity statin. Taking efficacy as well as safety into account, adopting a tailored approach may be considered for this high-risk population. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02579499.

AIMS: This study evaluated the effect of moderate-intensity statin with ezetimibe combination therapy vs. high-intensity statin monotherapy among patients with diabetes mellitus (DM) and atherosclerotic cardiovascular disease (ASCVD). METHODS AND RESULTS: This was a pre-specified, stratified subgroup analysis of the DM cohort in the RACING trial. The primary outcome was a 3-year composite of cardiovascular death, major cardiovascular events, or non-fatal stroke. Among total patients, 1398 (37.0%) had DM at baseline. The incidence of the primary outcome was 10.0% and 11.3% among patients with DM randomized to ezetimibe combination therapy vs. high-intensity statin monotherapy (hazard ratio: 0.89; 95% confidence interval: 0.64-1.22; P = 0.460). Intolerance-related discontinuation or dose reduction of the study drug was observed in 5.2% and 8.7% of patients in each group, respectively (P = 0.014). LDL cholesterol levels <70 mg/dL at 1, 2, and 3 years were observed in 81.0%, 83.1%, and 79.9% of patients in the ezetimibe combination therapy group, and 64.1%, 70.2%, and 66.8% of patients in the high-intensity statin monotherapy group (all P < 0.001). In the total population, no significant interactions were found between DM status and therapy regarding primary outcome, intolerance-related discontinuation or dose reduction, and the proportion of patients with LDL cholesterol levels <70 mg/dL. CONCLUSION: Ezetimibe combination therapy effects observed in the RACING trial population are preserved among patients with DM. This study supports moderate-intensity statin with ezetimibe combination therapy as a suitable alternative to high-intensity statins if the latter cannot be tolerated, or further reduction in LDL cholesterol is required among patients with DM and ASCVD.

Atrial fibrosis in the right atrium (RA) presenting as a low-voltage zone might be the mechanism of atrial fibrillation (AF) and intra-atrial conduction delay. The impact of scar homogenization in RA on intra-atrial conduction delay is unknown. We describe a patient with paroxysmal AF and significant intra-atrial conduction delay with repetitive atrial flutter, triggered from the lateral free wall in the RA between the significant low-voltage zone and slow conduction area after pulmonary vein isolation. Linear ablation along the trabeculated lateral free wall in the RA to homogenize the scar was successfully performed, and the intra-atrial conduction delay improved ultimately.

Importance: In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease. Objective: To assess whether a treat-to-target strategy is noninferior to a strategy of high-intensity statins for long-term clinical outcomes in patients with coronary artery disease. Design, Setting, and Participants: A randomized, multicenter, noninferiority trial in patients with a coronary disease diagnosis treated at 12 centers in South Korea (enrollment: September 9, 2016, through November 27, 2019; final follow-up: October 26, 2022). Interventions: Patients were randomly assigned to receive either the LDL-C target strategy, with an LDL-C level between 50 and 70 mg/dL as the target, or high-intensity statin treatment, which consisted of rosuvastatin, 20 mg, or atorvastatin, 40 mg. Main Outcomes and Measures: Primary end point was a 3-year composite of death, myocardial infarction, stroke, or coronary revascularization with a noninferiority margin of 3.0 percentage points. Results: Among 4400 patients, 4341 patients (98.7%) completed the trial (mean [SD] age, 65.1 [9.9] years; 1228 females [27.9%]). In the treat-to-target group (n = 2200), which had 6449 person-years of follow-up, moderate-intensity and high-intensity dosing were used in 43% and 54%, respectively. The mean (SD) LDL-C level for 3 years was 69.1 (17.8) mg/dL in the treat-to-target group and 68.4 (20.1) mg/dL in the high-intensity statin group (n = 2200) (P = .21, compared with the treat-to-target group). The primary end point occurred in 177 patients (8.1%) in the treat-to-target group and 190 patients (8.7%) in the high-intensity statin group (absolute difference, -0.6 percentage points [upper boundary of the 1-sided 97.5% CI, 1.1 percentage points]; P < .001 for noninferiority). Conclusions and Relevance: Among patients with coronary artery disease, a treat-to-target LDL-C strategy of 50 to 70 mg/dL as the goal was noninferior to a high-intensity statin therapy for the 3-year composite of death, myocardial infarction, stroke, or coronary revascularization. These findings provide additional evidence supporting the suitability of a treat-to-target strategy that may allow a tailored approach with consideration for individual variability in drug response to statin therapy.

Background and Objectives: Polymer-free ultrathin strut sirolimus- and probucol-eluting stents (PF-SES) are recognized as safe and effective in diverse patient populations, although the implications of post-dilation during stent implantation remain underexamined. Materials and Methods: In this study, patients implanted with PF-SES at Gachon University Gil Medical Center between December 2014 and February 2018 were evaluated. Major adverse cardiovascular events (MACE), encompassing nonfatal myocardial infarction (MI), nonfatal stroke, and cardiovascular death were identified as primary outcomes, with secondary outcomes including target vessel revascularization (TVR), target lesion revascularization (TLR), and in-stent restenosis (ISR). Results: Of the 384 initial patients, 299 were considered eligible for analysis. The groups, delineated by those undergoing post-dilation (143 patients) and those not (156 patients), exhibited comparable rates of primary outcomes [hazard ratio (HR), 2.17; 95% confidence interval (CI), 0.40 to 11.87; p = 0.37]. The outcomes remained consistent irrespective of the post-dilation status and were similarly unaffected in multivariate analyses (HR, 2.90; 95% CI, 0.52 to 16.34; p = 0.227). Conclusions: These results suggest that the clinical outcomes of patients with post-dilation were similar to that of those without post-dilation in those with the polymer-free sirolimus- and probucol-eluting stents.
RESUMO
BACKGROUND: For the Asian patients with STEMI undergoing PCI, ACEIs are known to have a better outcome than ARBs. However, there is limited evidence to suggest so. METHODS: Among the STEMI registry consist of 1142 Korean patients, we compared the MACE, the composite of myocardial infarction, stoke, death, admission for heart failure, and target vessel revascularization, between the ACEI and ARB groups (Set 1). Further, we defined adequate medication as the administration of a dose equal to or higher than the initiation dose of ACEI according to the heart failure guideline recommendation with a mandatory addition of beta-blockers, and compared the outcomes between the inadequate and adequate medication groups (Set 2). Propensity score matching was used to eliminate difference. RESULTS: In the Set 1 comparison, patients in the ACEI group had a better outcome than those in the ARB group for both whole and matched populations (whole and matched population: Cox regression hazard ratio [HR], 0.645 and 0.535; 95% confidence interval [CI], 0.440-0.944 and 0.296-0.967; p = 0.024 and p = 0.039, respectively). In the Set 2 comparison for the whole population, patients in the inadequate medication group had more MACE than those in the adequate medication group (HR, 0.673; 95% CI, 0.459-0.985; p = 0.042). However, no difference was observed after propensity score matching (HR, 1.023; 95% CI, 0.654-1.602; p = 0.919). CONCLUSION: ACEIs might be a better choice than ARBs after primary revascularization. However, this study's findings suggest that early ACEI dose escalation combined with beta-blocker use may not improve prognosis.

BACKGROUND: Differences in the impact of the 1- or 2-stent strategy in similar coronary bifurcation lesion conditions are not well understood. This study investigated the clinical outcomes and its predictors between 1 or 2 stents in propensity score-matched (PSM) complex bifurcation lesions.MethodsâandâResults: We analyzed the data of patients with bifurcation lesions, obtained from a multicenter registry of 2,648 patients (median follow up, 53 months). The patients were treated by second generation drug-eluting stents (DESs). The primary outcome was target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (TVMI), and ischemia-driven target lesion revascularization (TLR). PSM was performed to balance baseline clinical and angiographic discrepancies between 1 and 2 stents. After PSM (N=333 from each group), the 2-stent group had more TLRs (hazard ratio [HR] 3.14, 95% confidence interval [CI] 1.42-6.97, P=0.005) and fewer hard endpoints (composite of cardiac death and TVMI; HR 0.44, 95% CI 0.19-1.01, P=0.054), which resulted in a similar TLF rate (HR 1.40, 95% CI 0.83-2.37, P=0.209) compared to the 1-stent group. Compared with 1-stent, the 2-stent technique was more frequently associated with less TLF in the presence of main vessel (pinteraction=0.008) and side branch calcification (pinteraction=0.010). CONCLUSIONS: The 2-stent strategy should be considered to reduce hard clinical endpoints in complex bifurcation lesions, particularly those with calcifications.

BACKGROUND: The association between height and cardiovascular disease (CVD) has been reported in epidemiological studies for decades; however, the mechanism for this relationship is still unclear. We previously reported that dyslipidemia was associated with adult height in Korean men without CVD. OBJECTIVES: This study explored the potential -relationship between height and dyslipidemia in premenopausal women. METHODS: This study used data from the 2007-2016 Korea National Health and Nutritional Examination Survey (KNHANES). We identified 16,361 premenopausal women aged ≥19 years without a history of CVD (myocardial infarction/stroke) or cancer. Fasting total cholesterol, triglyceride, and high-density lipoprotein cholesterol (HDL-C) levels were measured. Dyslipidemia was further classified as hypercholesterolemia (total cholesterol level ≥240 mg/dL or treatment with lipid-lowering medications), hypertriglyceridemia (triglyceride level ≥200 mg/dL), and low HDL-C (HDL-C level <40 mg/dL). Subjects were divided into four groups by their height (<155, 155-159.9, 160-164.9, and ≥165 cm), and the prevalence of dyslipidemia was compared. RESULTS: Multiple regression analysis revealed that short premenopausal women had a higher likelihood of hypercholesterolemia (ptrend = 0.002), hypertriglyceridemia (ptrend = 0.010), and low HDL-C (ptrend = 0.002) when adjusted for age, comorbidities, waist circumference, health-related habits, and economic status. CONCLUSION: There was a dose-dependent correlation between adult height and adverse lipid profile in premenopausal Korean women who did not have CVD. This finding could serve as further evidence that dyslipidemia can be a link between shortness and CVD.

BACKGROUND: Several biomarkers have been proposed as independent predictors of poor outcomes in ST-segment elevation myocardial infarction (STEMI). We investigated whether adding information obtained from routine blood tests including hypoxic liver injury (HLI), dysglycemia, anemia, and high neutrophil to lymphocyte ratio (NLR) could improve the prognostic performance of the TIMI risk score for the prediction of 1-year mortality. METHODS: A total of 1057 patients with STEMI undergoing primary percutaneous coronary intervention (PCI) between 2007 and 2014 were retrospectively enrolled from 4-regional hospitals. HLI and dysglycemia were defined as serum transaminase > twice the normal upper limit and glucose < 90 or > 250 mg/dL, respectively. The effect of adding biomarkers to the TIMI risk score on its discriminative ability was assessed using c-statistic, net reclassification improvement (NRI), and integrated discrimination improvement (IDI). RESULTS: The 1-year mortality rate was 7.1%. The best cutoff value of NLR for the prediction of 1-year mortality was 4.3 (sensitivity, 67%; specificity, 65%). HLI (HR 2.019; 95% CI 1.104-3.695), dysglycemia (HR 2.535; 95% CI 1.324-3.923), anemia (HR 2.071; 95% CI 1.093-3.923), and high NLR (HR 3.651; 95% CI 1.927-6.918) were independent predictors of 1-year mortality. When these 4 parameters were added to the TIMI risk score, the c-statistic significantly improved from 0.841 to 0.876 (p < 0.001), and the NRI and IDI were estimated at 0.203 (95% CI 0.130-0.275; p < 0.001) and 0.089 (95% CI 0.060-0.119; p < 0.001), respectively. CONCLUSIONS: The addition of HLI, dysglycemia, anemia, and high NLR to the TIMI risk score may be useful for very early risk stratification in patients with STEMI receiving primary PCI.

BACKGROUND: The objective of the study was to investigate aortic remodeling and clinical outcomes after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (AD) according to timing of the procedure. METHODS: A total of 87 patients with type B AD who underwent TEVAR at 2 centers were included in this retrospective analysis. Patients were divided into acute/subacute (≤6 weeks, n = 35), early chronic (6 weeks to 1 year, n = 20), and late chronic (>1 year, n = 32) groups according to the timing of TEVAR after symptom onset. Changes in aorta dimensions on serial computed tomography angiograms and clinical outcomes were evaluated. RESULTS: AD complications were the most common indication for TEVAR in the acute/subacute group, whereas aortic expansion was the main reason in the early and late chronic groups. Maximum total aorta diameter (46.6 ± 10.6 vs. 54.8 ± 9.8 vs. 56.7 ± 10.1 mm, P < 0.001) and false lumen diameter (30.9 ± 11.0 vs. 35.2 ± 12.0 vs. 39.9 ± 13.4 mm, P = 0.013) were smaller in the acute/subacute group than in the early and late chronic groups. At 1-year follow-up, maximum total aorta diameter was decreased in the acute/subacute and early chronic groups and increased in the late chronic group (-4.3 ± 9.3 vs. -5.2 ± 6.9 vs. 2.5 ± 4.6 mm, P < 0.001). Survival free from the major adverse aortic event (death, aortic rupture, or reintervention) at 5 years after TEVAR was lowest in the late chronic group (92.6% vs. 88.2% vs. 73.1%, P = 0.033) but not significantly different between the acute/subacute and early chronic groups (P = 0.680). CONCLUSIONS: TEVAR in the acute/subacute and early chronic phases of type B AD resulted in similar aortic remodeling and clinical outcomes, which were more favorable than those with TEVAR performed during late chronic AD. This finding suggests 1 year after the onset of type B AD symptoms as the upper time threshold for TEVAR to achieve optimal aortic remodeling and safety.

BACKGROUND: The selection of ß-blocker for survivors after primary intervention due to acute ST-elevation myocardial infarction seems crucial to improve the outcomes. However, rare comparison data existed for these patients. We aimed to compare the effectiveness of selective ß-blockers to that of carvedilol in patients treated with primary intervention. METHODS AND RESULTS: Among the 1,485 patients in the "INTERSTELLAR" registry between 2007 and 2015, 238 patients with selective ß-blockers (bisoprolol, nebivolol, atenolol, bevantolol, and betaxolol) and 988 with carvedilol were included and their clinical outcomes were compared for a 2-year observation period. In the clinical baseline characteristics, the unfavorable trends in the carvedilol group were high Killip presentation, lower ejection fractions, smaller diameters, and longer lengths of deployed stents. Although mortality (2.5% vs. 1.7%; p = 0.414) and the rate of stroke (0.8% vs. 0.6%; p = 0.693) were not different between groups, the rate of recurrent myocardial infarction (4.6% vs. 1.2%; p = 0.001) and of target vessel revascularization (4.2% vs. 0.9%; p < 0.001) were lower in the carvedilol group. After eliminating the difference by propensity matching, the similar outcome result was shown (all-cause death, 0.6% vs. 1.0%, p = 0.678; stroke, 0.6% vs. 1.2%, p = 0.479; myocardial infarction, 5.0% vs. 1.2%, p = 0.003; target vessel revascularization, 4.5% vs. 0.7%, p < 0.006) for 595 matched populations. The use of carvedilol was also determined to be an independent predictor for recurrent myocardial infarctions (hazard ratio = 0.305; p = 0.005; 95% confidence interval = 0.13-0.69). CONCLUSION: Use of a carvedilol in ST-segment myocardial infarction survivor is associated with lower recurrent myocardial infarction events. Thus, it might be the better choice of ß-blocker for secondary prevention in ST-elevation myocardial infarction patients treated with primary percutaneous coronary intervention.

Background and Objectives: Transesophageal echocardiography (TEE) guidance is the current gold standard for catheter-based procedures in the treatment of structural heart diseases. Intracardiac echocardiography (ICE), which can be performed under local anesthesia, has been recently introduced and is becoming more widely used. We aimed to compare the efficacy and safety of ICE and TEE in patent foramen ovale (PFO) device closure. Materials and Methods: All 74 patients with a history of cryptogenic stroke undergoing PFO closure for secondary prophylaxis were selected from our registry. Intraprocedural TEE was performed by echocardiographer-cardiologists with the patient under general anesthesia. Conversely, ICE was performed with the patient under local anesthesia. Baseline characteristics, procedural details, and immediate outcomes were compared between the TEE and ICE groups (n = 49 and n = 25, respectively). Results: Although patients in the ICE group were older (47 ± 10 vs. 57 ± 7 years, p < 0.001), sex and comorbidity variables were similar between the two groups. The degree of inducible right-to-left shunt via the PFO, assessed using preprocedural TEE, was also comparable. Notably, fluoroscopy time (22 ± 18 vs. 16 ± 7 min, p = 0.030), radiation dose (498 ± 880 vs. 196 ± 111 mGy, p = 0.022), and total procedural time in the catheter laboratory (99 ± 30 vs. 67 ± 12 min, p < 0.001) were significantly lower in the ICE group than those in the TEE group. The entire hospital stay was similar between groups (3.8 ± 2.2 vs. 3.4 ± 1.3 days, p = 0.433). No procedural complications, such as device embolization, pericardial hemorrhage, major bleeding, mortality, or access-related vascular injury were reported in either group. Conclusions: ICE-guided PFO device closure is quicker and less hazardous in terms of radiation exposure than the TEE-guided procedure, with similar procedural outcomes and duration of hospital stay.

OBJECTIVES: We aimed to investigate specific subgroups in which the benefit of transradial coronary interventions (TRIs) would be enhanced. BACKGROUND: The advantage of TRIs over transfemoral coronary interventions (TFIs) might differ according to a given clinical condition, urgency of the procedure, and operator volume pattern. METHODS: Using a cohort from the 2014 Korean Percutaneous Coronary Intervention Registry, in-hospital outcomes of the TRI group (n = 22,993) were matched to those of the TFI group (n = 15,581). After propensity score matching, the composite endpoints between the groups and subgroups for all-cause death, nonfatal myocardial infarctions (MIs), or transfusions were analyzed. RESULTS: The composite endpoints occurred less frequently in the TRI group than the TFI group [2.1% vs. 5.5%, OR 0.63, 95% CI 0.55-0.72]. The TRI group had a lower rate of death (OR 0.44, 95% CI 0.33-0.60) and nonfatal MI (OR 0.66, 95% CI 0.54-0.81) than the TFI group. The TRI group required fewer transfusions than the TFI group (OR 0.72, 95% CI 0.59-0.88). TRI benefits were consistent across subgroups except patients with chronic kidney disease and those treated in low tertile PCI volume centers. The favorable outcome of TRI was greater in the elderly (≥75 years), patients with ST-elevation MI, those who underwent emergent PCI, and those treated in high tertile PCI volume hospitals (P for the interaction <0.001 for all). CONCLUSIONS: Compared to TFI, TRI had favorable composite in-hospital outcomes. TRI benefits were pronounced in high-risk clinical settings and in high PCI volume centers.

OBJECTIVES: This study sought to investigate neurological disability after ischemic cerebrovascular events in patients treated with left atrial appendage (LAA) occlusion compared with those on warfarin. BACKGROUND: Prior studies demonstrated that cerebrovascular events after LAA occlusion in patients with nonvalvular atrial fibrillation (NVAF) is largely nondisabling. METHODS: From the 1,189 patients in the Korean LAA Occlusion and European Amplatzer Cardiac Plug Multi-Center Registry, 24 patients who experienced ischemic cerebrovascular events after LAA occlusion were enrolled. The neurological outcomes were compared with those in 68 patients who experienced an ischemic cerebrovascular event while on warfarin (Yonsei Stroke Registry). A modified Rankin scale (mRS) score of 3-6 categorized the cerebrovascular event as disabling. The mRS at discharge and at 3 and 12 months postcerebrovascular event in the two groups was compared. RESULTS: The percentages of disabling cerebrovascular events were 37.5% and 58.8% at discharge (P = 0.07), 20.8% and 42.6% at 3 months (P = 0.08), and 12.5% and 39.7% at 12 months (P = 0.02) in the LAA occlusion and warfarin groups, respectively. The mRS was significantly lower in the LAA occlusion group at discharge and at 3 months (P < 0.01) and 12 months (P < 0.01) postcerebrovascular event despite no significant difference in mRS before cerebrovascular events (P = 0.98). Patients in the LAA occlusion group demonstrated a significant reduction in mRS between discharge and 12 months (P < 0.01), unlike patients in the warfarin group (P = 0.10). CONCLUSIONS: Ischemic cerebrovascular events in patients who previously underwent percutaneous LAA occlusion for NVAF were more favorable than in patients on warfarin.

BACKGROUND: Optimal stenting strategy for long femoropopliteal artery lesions still remains undefined. Longer stent length has been shown to be associated with increased risk of restenosis. We sought to compare the efficacy of spot versus long stenting in the treatment of femoropopliteal artery disease. METHODS: This study was designed as a multicenter randomized controlled trial to compare immediate and mid-term outcomes of spot versus long primary stenting for femoropopliteal arterial lesions. A total of 125 patients were randomized 1:1 to spot stenting group (n = 59) or long stenting group (n = 66). RESULTS: All lesions were treated with self-expanding bare nitinol stents. Baseline clinical and lesion characteristics were similar between the 2 groups except for male gender and current smoker. The mean lesion length was 24.1 ± 8.8 cm. Technical success was achieved in all patients. The 1-year primary patency and TLR-free (target lesion revascularization) survival did not differ significantly between the 2 groups. However, the spot stenting group showed a trend toward higher primary patency (86.1% vs. 72.7%, P = 0.158) and TLR-free survival (94.2% vs. 82.5%, P = 0.120). The total stented length (hazard ratio [HR] 1.01, 95% confidence interval [CI] 1.00-1.01, P = 0.011) and age (HR 0.94, 95% CI 0.90-1.00, P = 0.035) were independent predictors of restenosis. CONCLUSIONS: The spot stenting appears to be more favorable than the long stenting in terms of primary patency and TLR-free survival, although the difference was not statistically significant. The stented length was an independent predictor of restenosis.

BACKGROUND: Percutaneous closure of patent foramen ovale (PFO) is an alternative option to medical treatment for secondary prevention for cryptogenic stroke (CS). Despite technical success of procedure, residual shunt (RS) which is a presumable cause for recurrent stroke is observed in some patients. We evaluated the RS with serial follow-up bubble contrast transesophageal echocardiography (BCTEE) after PFO closure. METHODS: Among consecutive 47 CS patients who underwent PFO closure, a serial follow-up BCTEE at 3 and 9 months after the index procedure was completed in 38 patients (81%, 46 ± 10 years, 19 men). To evaluate the efficacy of PFO closure, the incidence of any and significant RS (≥ moderate) was assessed. RESULTS: All PFO closure procedures were successful. The Amplatzer PFO Occluder (nâ¯=â¯19) or the Gore Septal Occluder (nâ¯=â¯19) were used. Any RS was observed in 13 (34%) and 10 patients (26%) at 3 and 9 months after the procedure. Significant RS was observed in 6 (16%) and 4 (11%) patients at 3- and 9-month follow-up BCTEE. Patients who were treated with the Gore Septal Occluder have a less incidence of any RS in 3 months, and any/significant RS in 3- and 9-month follow-up BCTEE without statistical significance. CONCLUSIONS: RS grade keeps decreasing after PFO closure, but it remains even after 9 months in some patients. Incomplete sealing of PFO should be taken into consideration in management of CS patients even after technically successful PFO closure.

OBJECTIVES: This study was sought to evaluate the effectiveness of patent foramen ovale (PFO) closure in selected patients (PFO shunt grade more than moderate) with cryptogenic stroke (CS). BACKGROUND: Whether closure of PFO is an effective treatment for prevention of CS is still unclear. METHODS: Consecutive 158 patients (mean age: 49.9 years old, closure group: 67 patients, medication group: 91 patients) were enrolled. The primary end point was a composite of recurrent stroke and transient ischemic attack. RESULTS: Baseline characteristics were similar between the two groups, except age which was younger in the closure group (47.7 ± 10.8 vs 51.9 ± 9.9, P = 0.013), and the presence of shunt at rest was more common in the closure group (35.8% vs 10.4%, P = 0.000). Procedural success was 94.0%. Over a mean follow-up of 27.8 months, a total of six primary end point, all of which were strokes, occurred only in the medication group (6.6% vs 0%, P = 0.039). Stroke-free survival rate was significantly higher in the closure group (P = 0.026) CONCLUSIONS: Our study showed that PFO closure may be an effective treatment strategy to prevent recurrent stroke or TIA for patients with CS if it is conducted in selective patients who have PFO shunt more than moderate grade.
