Abstract
BACKGROUND Precise mapping of the Purkinje fiber network is essential in catheter ablation of Purkinje-related ventricular arrhythmias (PrVAs). We sought to evaluate the mapping ability of a multi-spline duodecapolar catheter (PentaRay) for PrVAs. METHODS Mappings of Purkinje fibers by PentaRay catheters were compared with those by conventional mapping catheters in consecutive patients undergoing catheter ablation of PrVAs from 2015 to 2022. RESULTS Sixteen PrVAs (7 premature ventricular contractions or non-reentrant fascicular tachycardias [PVCs/NRFTs] and 9 fascicular ventricular tachycardias [FVTs]) were retrospectively studied. In PVCs/NRFTs, earliest preceding Purkinje potentials (PPs) could be recorded by the PentaRay catheters but not by the mapping and ablation catheters in 5 cases. At the earliest PP sites, the precedence from the QRS onset was greater, and the amplitude of the preceding potentials was higher in the PentaRay catheter compared with those in the mapping and ablation catheter (-62.0 ± 42.8 vs. -29.4 ± 34.2 ms, P = 0.02; 0.45 ± 0.43 vs. 0.09 ± 0.08 mV, P = 0.02). In FVTs, late diastolic potentials (P1) were recorded by the PentaRay catheters but not by the mapping and ablation catheters or the linear duodecapolar catheter in 2 cases. The amplitude of P1 was higher in the PentaRay catheter compared with that in the linear duodecapolar catheter and the mapping and ablation catheters (0.72 ± 0.49 vs. 0.17 ± 0.18 vs. 0.27 ± 0.21 mV, P = 0.0006, P = 0.002). The localized critical PPs, defined as the earliest preceding potentials in PVCs/NRFTs and P1 in FVTs, could be recorded in all the patients by the PentaRay catheter. The mapping ability of critical PPs of PrVAs was better with the PentaRay catheter than with the conventional mapping catheters (16/16 vs. 9/16, P = 0.004 by McNemar exact test). CONCLUSIONS The PentaRay catheter has clinical advantages in mapping of the Purkinje fiber network to reveal critical PPs as ablation targets of PrVAs.

Abstract
AIM Several clinical trials using intravascular ultrasound (IVUS) evaluation have demonstrated that intensive lipid-lowering therapy by statin or a combination therapy with statin and ezetimibe results in significant regression of coronary plaque volume. However, it remains unclear whether adding ezetimibe to statin therapy affects coronary plaque composition and the molecular mechanisms of plaque regression. We conducted this prospective IVUS analysis in a subgroup from the CuVIC trial. METHODS The CuVIC trial was a prospective randomized, open, blinded-endpoint trial conducted among 11 cardiovascular centers, where 260 patients with coronary artery disease who received coronary stenting were randomly allocated into either the statin group (S) or the combined statin and ezetimibe group (S+E). We enrolled 79 patients (S group, 39 patients; S+E group, 40 patients) in this substudy, for whom serial IVUS images of nonculprit lesion were available at both baseline and after 6-8 months of follow-up. RESULTS After the treatment period, the S+E group had significantly lower level of low-density lipoprotein cholesterol (LDL-C; 80.9±3.7 vs. 67.7±3.8 mg/dL, p=0.0143). Campesterol, a marker of cholesterol absorption, and oxysterols (β-epoxycholesterol, 4β-hydroxycholesterol, and 27-hydroxycholesterol) were also lower in the S+E group. IVUS analyses revealed greater plaque regression in the S+E group than in the S group (-6.14% vs. -1.18% for each group, p=0.042). It was noteworthy that the lowering of campesterol and 27-hydroxycholesterol, but not LDL-C, had a significant positive correlation with plaque regression. CONCLUSIONS Compared with statin monotherapy, ezetimibe in combination with statin achieved significantly lower LDL-C, campesterol, and 27-hydroxycholesterol, which resulted in greater coronary plaque regression.

Abstract
Oxysterols have been implicated in the pathogenesis of cardiovascular diseases. Serum levels of oxysterols could be positively correlated with cholesterol absorption and synthesis. However, physiological regulation of various serum oxysterols is largely unknown. The aim of this study was to investigate the relationship between clinical factors and cholesterol metabolism markers, and identify oxysterols associated with cholesterol absorption and synthesis in patients with coronary artery disease. Subjects (n = 207) who underwent coronary stenting between 2011 and 2013 were studied cross-sectionally. We measured lipid profiles including serum oxysterols. As for the serum biomarkers of cholesterol synthesis and absorption, oxysterol levels were positively correlated with campesterol and lathosterol. Covariance structure analysis revealed that dyslipidemia and statin usage had a positive correlation with "cholesterol absorption". Statin usage also had a positive correlation with "cholesterol synthesis". Several oxysterols associated with cholesterol absorption and/or synthesis. In conclusion, we elucidated the potential clinical factors that may affect cholesterol metabolism, and the associations between various oxysterols with cholesterol absorption and/or synthesis in patients with coronary artery disease.

Abstract
Percutaneous coronary intervention (PCI) for complex lesions is still technically demanding and is associated with less favorable procedural parameters such as lower success rate, longer procedural time, higher contrast volume and unexpected complications. Because the conventional angiographic analysis is limited by the inability to visualize the plaque information and the occluded segment, cardiac computed tomography has evolved as an adjunct to invasive angiography to better characterize coronary lesions to improve success rates of PCI. Adding to routine image reconstructions by coronary computed tomography angiography, the thin-slab maximum intensity projection method, which is a handy reconstruction technique on an ordinary workstation, could provide easy-to-understand images to reveal the anatomical characteristics and the lumen and plaque information simultaneously, and then assist to build an in-depth strategy for PCI. Especially in the treatment of chronic total occlusion lesion, these informations have big advantages in the visualization of the morphologies of entry and exit, the occluded segment and the distribution of calcium compared to invasive coronary angiography. Despite of the additional radiation exposure, contrast use and cost for cardiac computed tomography, the precise analysis of lesion characteristics would consequently improve the procedural success and prevent the complication in complex PCI.

Abstract
Although a number of studies have demonstrated seasonal variations in acute cardiovascular events, the association between winter and low temperatures and the incidence rate of acute aortic dissection has not been fully elucidated. In this study, we investigated the association between meteorological and chronobiological factors and the occurrence of acute aortic dissection classified by the Stanford type, sex and age. We retrospectively collected 131 patients who had been admitted consecutively to our institution with acute aortic dissection, including 58 type A patients and 73 type B patients, from January 2013 to December 2017. The meteorological data were downloaded from the homepage of the Japan Meteorological Agency. The daily incidence of aortic dissection was higher in winter (10.2%) than in fall (5.3%) (P = 0.04), and a significant winter peak was also observed in the sub-groups of males and type B, while there were no significant differences in the proportions of type A, female, and ≤ 70- and > 70-year-old patients. The maximum, mean and minimum temperatures on the days with aortic dissection were significantly lower than on the days without aortic dissection. Divided into four seasons, lower temperatures were found only in spring. The most significant and greatest difference was observed between the maximum temperature on the day of aortic dissection and that at 2 days earlier. The multivariate logistic regression analysis showed that the difference in the maximum temperature between the day of and 2 days before the incident (odds ratio 0.91; 95% confidence interval 0.87-0.96; P < 0.01) as well as the maximum temperature (odds ratio 0.97; 95% confidence interval 0.95-0.99; P = 0.02) were significantly associated with the incidence of aortic dissection. Cold weather and a sudden decrease in temperature might trigger aortic dissection, although the influence might differ among sub-groups.

Abstract
BACKGROUND The feasibility of medical management for select patients with acute type A aortic dissection has been reported from a few institutions. In this study, we retrospectively investigated the safety and feasibility of our conservative approach for patients with type A aortic dissection in daily practice. METHODS From January 2013 to December 2017, 131 consecutive patients were admitted to our institution for acute aortic dissection, including 58 patients of type A. Initial medical management was attempted in select patients who were clinically stable and had a thrombosed false lumen of the ascending aorta without ulcer-like projections in the ascending aorta. RESULTS Except for nine patients contraindicated for surgery, urgent surgery was performed in 26 patients (SRG group), while 23 patients (MED group) were treated with the initial medical management. The maximum diameter of the ascending aorta was significantly larger in the SRG group than in the MED group. In the MED group, the heart rate and blood pressures were well-controlled at admission to the intensive-care unit, and the systolic blood pressure was further reduced at 24 h after. The in-hospital mortality rates of the MED and SRG groups were 0% and 15%, respectively. During the follow-up period, the survival rate was significantly higher in the MED group than in the SRG group, and the aortic event-free survival at one year was 80%. CONCLUSIONS The initial medical management for select patients with a thrombosed false lumen in the ascending aorta was a safe and feasible strategy in real-world practice.

Abstract
Objectives—
We sought to investigate whether treatment with ezetimibe in combination with statins improves coronary endothelial function in target vessels in coronary artery disease patients after coronary stenting.
Approach and Results—
We conducted a multicenter, prospective, randomized, open-label, blinded-end point trial among 11 cardiovascular treatment centers. From 2011 to 2013, 260 coronary artery disease patients who underwent coronary stenting were randomly allocated to 2 arms (statin monotherapy, S versus ezetimibe [10 mg/d]+statin combinational therapy, E+S). We defined target vessel dysfunction as the primary composite outcome, which comprised target vessel failure during treatment and at the 6- to 8-month follow-up coronary angiography and coronary endothelial dysfunction determined via intracoronary acetylcholine testing performed in cases without target vessel failure at the follow-up coronary angiography. Coadministration of ezetimibe with statins further lowered low-density lipoprotein cholesterol levels (83±23 mg/dL in S versus 67±23 mg/dL in E+S;
P
<0.0001), with significant decreases in oxidized low-density lipoprotein and oxysterol levels. Among patients without target vessel failure, 46 out of 89 patients (52%) in the S arm and 34 out of 96 patients (35%) in the E+S arm were found to have coronary endothelial dysfunction (
P
=0.0256), and the incidence of target vessel dysfunction at follow-up was significantly decreased in the E+S arm (69/112 (62%) in S versus 47/109 (43%) in E+S;
P
=0.0059). A post hoc analysis of post-treatment low-density lipoprotein cholesterol–matched subgroups revealed that the incidence of both target vessel dysfunction and coronary endothelial dysfunction significantly decreased in the E+S arm, with significant reductions in oxysterol levels.
Conclusions—
The CuVIC trial (Effect of Cholesterol Absorption Inhibitor Usage on Target Vessel Dysfunction after Coronary Stenting) has shown that ezetimibe with statins, compared with statin monotherapy, improves functional prognoses, ameliorating endothelial dysfunction in stented coronary arteries, and was associated with larger decreases in oxysterol levels.

Abstract
Background In this study, we investigated the feasibility of primary care physicians using carotid ultrasound to perform coronary artery disease screening in asymptomatic patients with multiple coronary risk factors. Methods We retrospectively collected the data of 135 consecutive asymptomatic patients (mean age: 68.5 ± 8.4 years; male, 75%) who were referred to our institution due to abnormal findings on a carotid ultrasound performed by a primary care physician and who underwent coronary computed tomography angiography. Results The mean number of risk factors was 4.1 ± 1.2 and the mean intima-media thickness was 2.00 ± 0.63 mm. Mild (≤ 50%), moderate (51-75%), and severe (> 76%) coronary stenosis was observed in 54 (40%), 27 (20%), and 25 patients (19%), respectively, while no plaque was found in 24 patients (18%), and five patients (4%) could not be evaluated due to calcification. Consequently, coronary angiography was performed in 56 (41%) patients and coronary intervention was required in 31 patients (23%). A multivariate logistic regression analysis demonstrated that the ratio of low-density lipoprotein cholesterol levels to high-density lipoprotein cholesterol levels, the use of calcium channel blockers and the value of the diastolic blood pressure were related to > 50% coronary stenosis. Conclusions The use of carotid ultrasound in the coronary artery disease screening by primary care physicians resulted in a high prevalence of coronary artery disease and high probabilities of coronary angiography and revascularization, and thus it is considered to be a useful and feasible strategy for the screening of asymptomatic patients.

Abstract
Objective The aim of this study was to investigate whether the use of low frame rate fluoroscopy at 7.5 frames per second during coronary intervention could reduce radiation exposure in Japanese patients. Methods From December 10, 2014 to March 20, 2015, 84 consecutive patients with coronary artery disease who underwent coronary intervention in our institution were retrospectively collected and then divided into two groups: the LR group (fluoroscopy at 7.5 frames per second) and the OR group (fluoroscopy at 15 frames per second), according to the frame rate of fluoroscopy that was used in their treatment. Results There were no differences in the patient backgrounds or the procedural characteristics of the two groups. Although there were no differences in the contrast volume or fluoroscopy time, the total air kerma at the interventional reference point, which is used to monitor the patient's radiation dose, was significantly lower in the LR group than in the OR group (701.4±427.9 vs. 936.8±623.9 mGy, p=0.02). Conclusion Low frame rate fluoroscopy at 7.5 frames per second is safe and feasible for use during coronary interventions and an easy and useful strategy for reducing the radiation to which patients are exposed during coronary intervention.

Abstract
BACKGROUND Beta-blockers are used to control the heart rate prior to coronary computed tomography (CT) angiography. However, in-hospital administration is time-consuming, and it is hard to decrease the heart rate to <60 beats per minute (bpm) when the initial heart rate is increased. In this study, we examined whether the single administration of long-acting β-blocker at bedtime before angiography is effective for achieving the target heart rate. METHODS AND RESULTS A total of 314 consecutive patients with a resting heart rate >60bpm who underwent coronary CT angiography were retrospectively collected. Either bisoprolol or atenolol was orally administered the night before to 166 patients (beta group), and no additional medication was administered to the other 148 patients (control group). When the heart rate was >60bpm on arrival, a β-blocker or verapamil was orally administered at the discretion of the physician. Although the baseline heart rate was not significantly different between the groups, the β-blocker treatment the night before significantly reduced the heart rate compared to control group upon arrival at the hospital and at the time of angiography. The rate of achievement of a heart rate ≤60bpm on arrival at the hospital was significantly higher in the beta group, and even after the additional treatment. CONCLUSIONS Bedtime administration of a long-acting β-blocker the night before coronary CT angiography is an effective option to achieve the target heart rate at the time of examination.

Abstract
A 79-year-old male, with a history of percutaneous coronary intervention (PCI), was referred to our cardiovascular department for a detailed examination of blackout caused by sinus arrest only during meals. Ultrasound echocardiography showed normal cardiac contraction with no asynergy, irrespective of the remaining stenotic coronary lesion. An electrophysiological study revealed deteriorated atrioventricular nodal conduction at a Wenckebach point of 70 beats per minute. However, sinus node function was normal as demonstrated by a sinus node recovery time of 1369 ms. Coronary angiography showed triple-vessel disease including the remaining stenotic coronary lesion, and a PCI was performed on the right coronary artery. Nevertheless, sinus arrest during meals was unchanged. Swallow syncope was partially improved by dietary modification; however, pacemaker implantation (PMI) was performed eventually, and the patient became asymptomatic after PMI. <Learning objective: Swallow syncope is a rare cause of syncope that belongs to the neurally mediated reflex syncopal syndromes, which can induce a variety of bradyarrhythmias: sinus bradycardia, sinus arrest, sinoatrial block, atrioventricular block, or atrial and ventricular asystole. In this case, we demonstrated that dietary modification or pacemaker implantation improved swallow syncope due to sinus arrest.>.

Abstract
An 80-year-old man, who had dilated cardiomyopathy with right ventricular (RV) dilatation, underwent implantable cardioverter defibrillator (ICD) implantation for advanced atrioventricular block and primary prevention of sudden cardiac death. Tined and screw-in leads were placed on the right atrial appendage and RV apex, respectively. Ventricular pacing inhibition was detected after surgery due to oversensing by diaphragmatic myopotential occurring only during deep inspiration. We performed re-surgery and switched the screw-in lead for a tined lead. The diaphragmatic myopotential decreased, thereby improving oversensing by diaphragmatic myopotential and ventricular pacing inhibition. It might be beneficial to use a tined lead when placing the ventricular lead at the RV apex for implantation of a pacemaker or ICD if oversensing of diaphragmatic myopotential is observed using a screw-in lead. <Learning objective: Oversensing due to diaphragmatic myopotential is rarely observed. However if it occurs, it becomes a critical problem, which causes pacemaker inhibition or inappropriate ICD shock. However, the method of preventing this problem is unknown. In this case, we demonstrated that a tined-lead may be useful for the prevention of oversensing by diaphragmatic myopotential.>.

Abstract
This report presents the case of a 54-year-old female with Takotsubo cardiomyopathy that recurred 12 years after the first episode. The coronary angiography at the first admission revealed ergonovine-induced coronary vasoconstriction in the left coronary artery, and recurrence recurred after the interruption of vasodilator therapy to prevent vasospasm. In addition, the coronary angiography both in the first and second event demonstrated coronary slow flow phenomenon, which improved after the intracoronary administration of nicorandil. These findings indicate that coronary microvascular constriction plays an important role in the pathophysiology of Takotsubo cardiomyopathy.

Abstract
BACKGROUND Electrical isolation of the pulmonary veins (PV) is crucial for atrial fibrillation (AF) ablation. Conduction gaps on the circumferential PV antrum ablation (CPVA) line sometimes remain, which are sometimes difficult to identify. METHODS AND RESULTS CPVA of the ipsilateral superior and inferior PVs was performed during sinus rhythm or coronary sinus pacing using the NavX system in 22 AF patients, in whom 1 round of CPVA failed to disconnect 26 individual PVs (30%) in 18 patients. In these patients, a local activation map within the CPVA line (PV map) was created by a 20-pole circular mapping catheter with the use of the NavX, with 71 ± 37 sampling points per PV antrum. The conduction gap was defined as a site on the CPVA line, from which the activation proceeded toward the entire PV. The mapped PV antra were comprised of the left superior PV in 11, right superior PV in 10, left inferior PV in 3, right inferior PV in 1 and a left common PV in 1 PV(s). The conduction gaps were identified at 1.4 ± 0.7 sites per PV antrum, with an electrogram amplitude of 0.8 ± 0.7 mV. A point ablation at the gap completely isolated 24 out of 26 PV antra (92%) with 1.9 ± 1.3 applications. CONCLUSIONS The PV map was useful for quickly and accurately identifying the conduction gap(s) after 1 round of CPVA.

Abstract
Diffuse alveolar hemorrhage after percutaneous coronary intervention is a rare complication that has been mostly reported in association with glycoprotein IIb/IIIa inhibitors. We herein report a case of a 64-year-old male who developed a diffuse pulmonary hemorrhage after coronary stent implantation for ST-elevation myocardial infarction. Diagnostic bronchoscopy determined the hemorrhage to be a bland pulmonary hemorrhage, and this pattern suggested that combination therapy with aspirin and ticlopidine was therefore the most likely cause. The combination of aspirin and thienopyridine agents is a routine therapeutic protocol for patients after coronary stent implantation. Therefore, physicians should be aware that this dual antiplatelet therapy might sometimes induce fatal complications.

Abstract
BACKGROUND The elevated D-dimer value is one of the clues used to diagnose acute aortic dissection (AAD), but the rapid D-dimer assay is not used at all emergency hospitals. The fibrinogen/fibrin degradation products (FDP) value is also an indicator of enhanced fibrinolysis and may therefore be a useful marker in patients with AAD. In addition, the association between FDP values and partial thrombosis of the false lumen is not elucidated. PATIENTS The present study enrolled 50 patients (66.5±11.2 years of age; median, 66.5 years of age, male subjects comprised 60.0% of the series) with AAD who were admitted to the hospital between July 2005 and December 2007 and 57 patients with acute myocardial infarction (AMI; 70.8±10.4 years of age; median, 71.0 years of age, male subjects comprised 71.9% of the current series) served as a control group. RESULTS The FDP values (µg/mL) in patients with AAD were significantly higher than those of AMI patients (40.2±78.6; median, 14.7 vs. 5.2±9.8; median, 1.7, p<0.001). A receiver operating characteristic curves analysis showed that an elevated FDP level (2.05 µg/mL) was predictive of a diagnosis of AAD with a sensitivity and specificity of 98% and 54%, respectively. The FDP levels of patients (n=14) who had partial thrombosis of the false lumen were significantly higher than in discharged patients without a surgical repair (n=21) who had a patent or complete thrombosis of the false lumen (35.8±43.2; median, 18.8 vs. 14.0±21.3; median, 5.5, p=0.01). CONCLUSION The measurement of FDP may therefore be useful for the initial assessment of patients with suspected AAD and in the prediction of thrombotic status of the false lumen.

Abstract
We report a case of a patient with exertional angina whose coronary angiography showed a severe stenosis at the ostium of the left coronary anterior descending artery. However, intravascular ultrasound imaging demonstrated only mild plaque burden and negative remodeling, with a 0.66 ratio of external elastic membrane area of the lesion to the distal site. The lesion was successfully treated with stenting. Therefore, our case suggests that negative remodeling at an ostial lesion could be the primary cause of myocardial ischemia.
