RESUMO
The authors performed this study to investigate the efficacy and safety of a rosuvastatin (RSV)/amlodipine (AML) polypill compared with those of atorvastatin (ATV)/AML polypill. We included 259 patients from 21 institutions in Korea. Patients were randomly assigned to 1 of 3 treatment groups: RSV 10 mg/AML 5 mg, RSV 20 mg/AML 5 mg, or ATV 20 mg /AML 5 mg. The primary endpoint was the efficacy of the RSV 10.20 mg/AML 5 mg via percentage changes in LDL-C after 8 weeks of treatment, compared with the ATV 20 mg /AML 5 mg. There was a significant difference in the mean percentage change of LDL-C at 8 weeks between the RSV 10 mg/AML 5 mg and the ATV 20 mg/AML 5 mg (full analysis set [FAS]: -7.08%, 95% CI: -11.79 to -2.38, p = .0034, per-protocol analysis set [PPS]: -6.97%, 95% CI: -11.76 to -2.19, p = .0046). Also, there was a significant difference in the mean percentage change of LDL-C at 8 weeks between the RSV 20 mg/AML 5 mg and the ATV 20 mg/AML 5 mg (FAS: -10.13%, 95% CI: -15.41 to -4.84, p = .0002, PPS: -10.96%, 95% CI: -15.98 to -5.93, p < .0001). There was no significant difference in the adverse events rates between RSV 10 mg/AML 5 mg, RSV 20 mg/AML 5 mg, and ATV 20 mg/AML 5 mg. In conclusion, while maintaining safety, RSV 10 mg/AML 5 mg and the RSV 20 mg/AML 5 mg more effectively reduced LDL-C compared with the ATV 20 mg /AML 5 mg (Clinical trial: NCT03951207).

Takayasu arteritis (TA) is a disease that causes inflammation and stenosis of medium to large blood vessels. We report a case of a 50-year-old female patient with newly developed hypertension, syncope, and claudication of the extremities. Total occlusion of the left subclavian artery at the origin was found and significant stenosis of the right common iliac artery was revealed by hemodynamic analysis. She was successfully treated with percutaneous angioplasty for multiple peripheral arterial diseases and was finally diagnosed with TA. In consultation with a rheumatologist, medical treatment for TA was initiated, the patient's hypertension disappeared, and her claudication symptoms improved.
RESUMO
OBJECTIVES: This study aimed to evaluate the long-term prognostic value of E/e' ratio in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: We retrospectively assessed 314 patients who underwent primary coronary interventions between January 2010 and December 2015. The included patients were classified into two groups according to the E/e' ratios: E/e'<15 (n = 245) and E/e'≥15 (n = 69). We investigated the incidence of major adverse cardiac events (MACEs) from the event to the final follow-up period of at least three years. RESULTS: A total of 55 cases of MACEs occurred during the follow-up. The E/e'≥15 group showed a significantly higher rate of MACEs than the E/e'<15 group (34.8% vs. 12.7%, p < 0.001). Among the MACE, the percentage of cardiac deaths (17.4% vs. 0.4%, p < 0.001) was higher in the E/e'≥15 group than in the E/e'<15 group. In the multivariable model, E/e'≥15 was demonstrated as the strongest prognostic factor for MACEs (hazard ratio [HR], 2.597; 95% confidence interval [CI], 1.294-5.211; p = 0.007) and cardiac death (HR, 27.537; 95% CI, 3.287-230.689; p = 0.002), while left ventricular ejection fraction (LVEF) was not. Neither the discrepancy of systolic nor diastolic function between initial and follow-up echocardiography affected the overall prevalence of MACEs. A disparity was observed between the two groups, with a significant increase in the rate of MACEs in the E/e'≥15 group (log-rank test, p < 0.001). CONCLUSION: The baseline E/e'≥15 in patients with STEMI after successful reperfusion is the strongest predictor of poor long-term clinical outcomes among those analyzed.

Rhythm control strategies in patients with atrial fibrillation (AF) can bring many clinical benefits. However, there is still uncertainty regarding selection of the optimal rhythm control strategy for persistent AF. Chronicity, substrate alteration, and underlying bradyarrhythmias could influence the clinical outcomes. Current guidelines do not provide a distinct recommendation for electrical cardioversion (ECV) in patients with AF with a slow ventricular response (SVR). We present two cases of sudden cardiac arrest due to sustained ventricular tachycardia/fibrillation after ECV of persistent AF with SVR.

Diagnosis of myocardial abscess without endocarditis is challenging, and a high index of clinical suspicion is fundamental for diagnosis. It should never be ruled out before TEE. And CT could be a helpful modality in case of emphysematous morphology.
RESUMO
Myocarditis is an inflammatory disease of the myocardium with high morbidity and mortality; however, definite prognostic factors are still unclear. Therefore, we aimed to evaluate the predictor of clinical outcomes of acute myocarditis focusing on electrocardiographic findings. The overall result of the study consists of a total of 51 patients demonstrated that wide QRS duration is a meaningful factor for predicting the fulminant course of acute myocarditis. This finding may encourage timely mechanical support resulting in better clinical outcomes.

BACKGROUND: Intracoronary (IC) provocation angiography is recommended when variant angina is suspected. However, specific procedure-related factors remain uncertain. METHODS: Intracoronary ergonovine infusion was used for the provocation test. About 10, 20, and 40 µg of ergonovine were sequentially injected into the right coronary artery (RCA). During a negative or intermediate response or depending on the clinician's discretion, the left coronary artery (LCA) was injected with incremental doses of 20, 40, and 80 µg of ergonovine or vice versa. If significant coronary spasm or positive clinical findings were noted, the test was stopped immediately and IC nitroglycerine was injected. RESULTS: We reviewed a total of 725 patients (male: 402; mean age: 58.5 years). Spasm-positive response was observed in 269 patients (37.1%), intermediate response in 113 patients (15.6%), and negative response in 343 patients (47.3%). The right radial artery approach was used in most cases (92.6%), and the RCA first approach was mainly chosen (95.0%). The provocation results in the RCA and LCA (93.4%, 381/408) were highly consistent, and the clinically significant discrepancy rate (RCA positive/LCA negative or RCA negative/LCA positive) was 1.5% (6/408). The RCA-alone provocation test can identify spasm-positive response in 93.4% of the patients (228/244). The mean procedure time was 39.9 ± 11.0 min, and approximately 3.3% (24/725) of the patients developed acute complications. CONCLUSIONS: The RCA-first IC ergonovine provocation test is feasible, and the RCA-alone spasm provocation could be acceptable except in an intermediate response, highly clinically suspected cases, or high-risk patients.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of systemic vasculitis in which cardiac involvement is relatively common and accounts for half of EGPA-related deaths. Cardiac involvement is more frequent in patients with an absence of anti-neutrophil cytoplasmic antibody and those with higher eosinophil counts. Clinical manifestations are various, including myocarditis, pericarditis, pericardial effusion, heart failure, arrhythmias, valvular insufficiencies and intra-cardiac thrombus formation. The pathology of cardiac involvement in EGPA is usually endomyocardial and pericardial eosinophilic infiltration. Considering the potentially adverse outcomes associated with cardiac involvement in EGPA, early detection is important. We experienced a rare case of EGPA with cardiac involvement presenting with non-infectious vegetations.

Schwannoma is usually benign, encapsulated spindle cell tumor which arises from schwann cells of nerve sheath, and is the most common of the neurogenic mediastinal tumors. Various imaging modalities can be applied to assess posterior mediastinal mass which is often found incidentally without symptom and frequently misdiagnosed for other benign conditions both clinically and radiologically in which clinicians should be aware of.
RESUMO
Left ventricular pseudo-aneurysm is a rare complication that usually occurs after myocardial infarction or cardiac surgery. Sometimes it is related to cardiac rupture. We report on surgical management for a left ventricular pseudo-aneurysm that developed four years after surgery for ventricular septal defect in a patient with acute myocardial infarction.

BACKGROUND AND OBJECTIVES: The earliest atrial (A)/ventricular (V) activation potential, or accessory pathway (AP) potential are commonly used as ablation targets for atrioventricular (AV) APs. However, these targets are sometimes ambiguous. SUBJECTS AND METHODS: We reviewed 119 catheter ablation cases in 112 patients diagnosed with orthodromic atrioventricular reentrant tachycardia (AVRT) or Wolff-Parkinson-White (WPW) syndrome. Local A/V amplitude potentials with the earliest activation or AP potential were measured shortly before achieving antegrade AP conduction block, ventriculoatrial block during right ventricle (RV) pacing, or AVRT termination with no AP conduction. RESULTS: APs were located in the left lateral (55.5%), left posterior (17.6%), left posteroseptal (10.1%), midseptal (1.7%), right posteroseptal (7.6%), right posterior (1.7%), and right lateral (5.9%) regions. The mean earliest activation time was 16.7±15.5 ms, mean A/V potential was 1.1±0.9/1.0±0.9 mV, and mean A/V ratio was 1.7±2.0. There was no statistically significant difference between the activation methods (antegrade vs. RV pacing vs. orthodromic AVRT) or AP locations (left vs. right atrium). However, when the local A/V ratio was divided into 3 groups (≤0.6, 1.0±0.3, and ≥1.4), the antegrade approach resulted in an A/V ratio greater than 1.0±0.3 (86.7%, p=0.007), and the orthodromic AVRT state resulted in a ratio of less than 1.0±0.3 (87.5%, p<0.001). CONCLUSION: The mean local A/V potential and ratio did not differ by activation method or AP location. However, a different A/V ratio based on activation method (≥1.0±0.3, antegrade approach; and ≤1.0±0.3, orthodromic AVRT state) could be a good adjuvant marker for targeting AV APs.
RESUMO
Objective We aimed to determine whether the extension of ablation could influence the ablation outcome for ventricular tachycardia (VT)/premature ventricular contractions (PVCs) from the right ventricular outflow tract (RVOT). Methods and results The radiofrequency catheter ablation results of 33 VT/6 frequent PVCs from the RVOT were analysed. The ablation extension was divided into 3 categories from the final successful ablation point with the earliest activation: (I) focal ablation (15 cases); ablation at 1 or 2 points; (II) focal with extended ablation (12 cases); focal and surrounding area ablation (maximum ≤1 cm) after elimination of clinical VT/PVCs; and (III) broad ablation (12 cases); continued broad ablation (maximum >1 cm) after elimination of clinical VT/PVCs. Acute termination was defined as the complete elimination and non-inducibility of clinical VT/PVCs during the procedure. For the mean follow-up of 12.8 months, the recurrence rate was not significantly different among the groups (P = 0.49). The mean procedure time was longer in group II, but ablation times and complication rates were not different among the groups. When acute termination was achieved, the overall recurrence rate was 7.6%. However, when confirming absence of the clinical VT/PVCs using 24-hour Holter monitoring immediately after the procedure, the recurrence rate was 2.7%. Conclusions Ablation extension did not affect ablation outcome of VT/PVCs from the RVOT. Confirmation of absence of clinical VT/PVCs using 24-hour Holter monitoring immediately after the procedure could guarantee long-term success.
