Cytomegalovirus (CMV) infection in immunocompromised patients is associated with significant morbidity, mortality, and adverse clinical outcome. However, CMV infection in immunocompetent patients has been considered to have subclinical and self-limited course, and does not require treatment. We reports a case of CMV colitis, presented with colon perforation and lower gastrointestinal bleeding in a immunocompetent 31-year-old young male. After conservative treatment, colonoscopy revealed multiple ulcers in transverse colon. CMV colitis was confirmed by microscopic findings and immunohistochemistry. After successful treatment with ganciclovir, the patient improved without invasive procedure.

Double atrial septum is very rare atrial septal malformation which has double layered atrial septum with persistent interatrial space between the two atria. Clinically, most cases of this anomaly are asymptomatic unless manifest as thromboembolic complications, such as stroke, or transient ischemic attack, that thrombus may be originated from this interatrial space. We report a case of a 69-year-old man who was diagnosed with isolated double atrial septum by transthoracic echocardiography.

Despite the necessity of surgical aortic valve replacement, many patients with symptomatic severe aortic stenosis (AS) cannot undergo surgery because of their severe comorbidities. In these high-risk patients, percutaneous transcatheter aortic valve implantation (TAVI) can be safely accomplished. However, no study has shown that TAVI can be performed for patients with severe AS accompanied by acute decompensated heart failure. In this case report, 1 patient presented a case of severe pulmonary hypertension with decompensated heart failure after diagnosis with severe AS, and was successfully treated via emergency TAVI. Without any invasive treatment, acute decompensated heart failure with severe pulmonary hypertension is common in patients with severe AS, and it can increase mortality rates. In conclusion, TAVI can be considered one of the treatment options for severe as presented as acute decompensated heart failure patients with pulmonary hypertension.

With the aging population, more patients who have undergone previous coronary artery bypass grafting (CABG) are surviving long enough to require subsequent aortic valve replacement (AVR). Conventional redo AVR after prior CABG involves resternotomy, dissection and clamping of the patent bypass graft vessel. Favorable results have been reported for AVR following previous CABG; however, the problems of this procedure includes that injury to the patent bypass grafts can result in catastrophic complications. Increasing patient age and comorbidities may increase operative mortality, less invasive percutaneous aortic valve intervention has advanced. However, because there are no sufficient data comparing transcatheter aortic valve intervention with surgical AVR, currently, the surgical approach should still be consider as the standard of treatment for AVR following previous CABG. We report a patient in whom successful conventional AVR was underwent after previous CABG with patent left internal mammary artery.

Thyroglossal duct cyst (TGDC) carcinoma generally shows a favorable prognosis. If metastasis is present latently, it may not threaten the patient's life immediately. It has been shown, however, that larger than 1 cm papillary carcinoma (PC), level VI metastasis to the lymph node (LN), which is the nearest to the thyroid, independently predicts a worse prognosis. In the case presented herein, a 61-year-old female patient was diagnosed with an about 3 cm PC in the TGDC, particularly the columnar variant subtype, one of the aggressive variants. She had occult papillary thyroid microcarcinoma, but no LN metastasis. Even though she underwent the Sistrunk procedure and total thyroidectomy with central compartment neck dissection followed by high-dose radioactive iodine remnant ablation, however, the cancer cells spread to level IV neck LN, and finally to the lung. Therefore, when a patient is diagnosed with an aggressive histologic variant of PC in the TGDC, even without LN metastasis, the invasive surgical approach and close postoperative surveillance are necessary, with consideration of the risk of disease progression. Therefore, if it is possible to stratify the risk for patients, higher-risk patients can be offered a more invasive therapeutic approach.

Esophageal involvement of pemphigus vulgaris is rare, and when present, the most common presenting symptoms reported in the medical literature are odynophagia and dysphagia. Here, we present two cases of pemphigus vulgaris presenting with upper gastrointestinal hemorrhage because of esophageal involvement of the disease. In case 1, a 41-year-old female patient with a prior diagnosis of pemphigus vulgaris presented with hematemesis. Esophagogastroduodenoscopy showed diffuse mucosal exfoliation and oozing bleeding of the oropharynx and esophagus. The patient recovered after the administration of high-dose corticosteroids and immunosuppressants. In case 2, a 30-year-old female patient with known pemphigus vulgaris also presented with hematemesis, showing similar endoscopic findings to the first case. She also responded to the same treatment. Esophageal involvement of pemphigus vulgaris responds to high-dose corticosteroids and immunosuppressants. Thus, in patients with pemphigus vulgaris with signs or symptoms of upper gastrointestinal bleeding, an early endoscopy for the evaluation of esophageal involvement is beneficial.

PURPOSE: The identification of sick sinus syndrome (SSS) in patients with atrial flutter (AFL) is difficult before the termination of AFL. This study investigated the patient characteristics used in predicting a high risk of SSS after AFL ablation. MATERIALS AND METHODS: Out of 339 consecutive patients who had undergone radiofrequency ablation for AFL from 1991 to 2012, 27 (8%) had SSS (SSS group). We compared the clinical characteristics of patients with and without SSS (n=312, no-SSS group). RESULTS: The SSS group was more likely to have a lower body mass index (SSS: 22.5+/-3.2; no-SSS: 24.0+/-3.0 kg/m2; p=0.02), a history of atrial septal defects (ASD; SSS: 19%; no-SSS: 6%; p=0.01), a history of coronary artery bypass graft surgery (CABG; SSS: 11%; no-SSS: 2%; p=0.002), and a longer flutter cycle length (CL; SSS: 262.3+/-39.2; no-SSS: 243.0+/-40; p=0.02) than the no-SSS group. In multivariate analysis, a history of ASD [odds ratio (OR) 3.7, 95% confidence interval (CI) 1.2-11.4, p=0.02] and CABG (7.1, 95% CI 1.5-32.8, p=0.01) as well as longer flutter CL (1.1, 95% CI 1.0-1.2, p=0.04) were independent risk factors for SSS. CONCLUSION: A history of ASD and CABG as well as longer flutter CL increased the risk of SSS after AFL ablation. While half of the patients with SSS after AFL ablation experienced transient SSS, heart failure was associated with irreversible SSS.

PURPOSE: Despite undergoing successful catheter ablation of typical atrial flutter (AFL), patients remain at increased risk for ischemic stroke. However, data on risk prediction tools for the development of stroke after AFL ablation are lacking. This study investigates whether CHA₂DS₂-VASc score is useful for predicting ischemic stroke after successful ablation of typical AFL. MATERIALS AND METHODS: A total of 293 patients (236 men, mean age 56.1±13.5 years) who underwent successful radiofrequency catheter ablation for typical AFL were included in this study. The clinical end point was occurrence of ischemic stroke during follow-up after AFL ablation. RESULTS: During the follow-up period (60.8±45.9 months), ischemic stroke occurred in 18 (6%) patients at a median of 34 months (interquartile range, 13–65 months). CHA₂DS₂-VASc score [hazard ratio 2.104; 95% confidence interval (CI), 1.624–2.726; p < 0.001] was an independent predictor for the occurrence of stroke after AFL ablation. The area under the receiver operating characteristic curve for CHA₂DS₂-VASc score was 0.798 (95% CI, 0.691–0.904). The CHA₂DS₂-VASc score could be used to stratify patients into two groups with different incidences of ischemic stroke (1.6% vs. 14.4%, p < 0.001) at a cutoff value of 2. CONCLUSION: CHA₂DS₂-VASc score is useful in a prediction model for the risk of stroke after catheter ablation of typical AFL.

Purpose:
Only a few Asian studies have discussed the impact of statin intensity on clinical outcomes in patients with peripheral artery disease (PAD). We aimed to investigate the clinical impact of statin intensity in patients with PAD after endovascular revascularization.
Materials and Methods:
From April 2009 to June 2019, 376 patients with lower extremity PAD treated with endovascular revascularization were enrolled. They were classified into three groups according to statin intensity: no-statin, low-to-moderate intensity (LMI), and high-intensity (HI). The primary outcomes were major adverse cardiovascular events (MACE) and major adverse limb events (MALE).
Results:
During the 40-month follow-up, MACE occurred less frequently in the HI and LMI groups than the no-statin group (11.4% vs. 16.0% vs. 39%, p<0.001). In adjusted Cox models, the HI group had the fewest MACE [hazard ratio (HR): 0.447; 95% confidence interval (CI): 0.244–0.834; p=0.018] and MALE (HR: 0.360; 95% CI: 0.129–1.006; p=0.051) events, while the LMI group had fewer MACE (HR: 0.571; 95% CI: 0.326–1.0; p=0.050) events than the no-statin group. HI statin therapy was associated with better outcomes in terms of MALE (HR: 0.432; 95% CI: 0.223–0.837; p=0.003) than LMI statin therapy after inverse probability treatment weighting analysis.
Conclusion
HI and LMI statin use is associated with a significant reduction in MACE events than no-statin use. HI statin use was associated with better MALE outcomes than no-statin or LMI statin use.
