We report on a patient with Behcet's syndrome who had two pseudoaneurysms at the junction of a saphenous vein graft and the native common carotid artery. He had experienced graft interposition due to the aneurysm rupture, but the saphenous vein was interpositioned due to the graft reobstruction. We successfully repaired the pseudoaneurysms with stent-graft.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the age-related differences in clinical features, coronary anatomy, risk factors, hospital courses, and long-term prognosis of acute myocardial infarction(AMI) in women. MATERIALS AND METHODS: Total 513 female patients with AMI were divided into 3 groups ; group 1(n=3, 50 years old or less), group 2(n=02, between 51 years and 70 years old), and group 3(n=68, older than 70 years). Clinical follow-up including cardiac events was performed for mean duration of 26 months(1~155 months). Cardiac events include cardiac death, reinfarction, CABG, PTCA, CHF, stroke, and recurrent angina. RESULTS: Minimal lesion(<50% stenosis) in infarct-related artery was more prevalent in group 1 than in group 3(p<0.05). In group 2, the number of low high density lipoprotein(HDL) was significantly more than in group 3(p<0.01). During hospitalization, death and shock were more prevalently observed in group 3 than group 1(p<0.005) and group 2(p<0.001). Group 3 had more heart failures than group 1(p<0.001) and group 2(p<0.001) and group 2 had more heart failures than group 1(p<0.05). The younger age group showed a significantly higher survial rate(7 years : group 1; 76.1%, group 2; 60.6%, group 3; 34.2%, p<0.0001, Log Rank Stat =49.4) and cardiac event-free survival rate(7 years : group 1; 48.4%, group 2; 32.3%, group 3; 16.0%, p<0.0001, Log Rank Stat =37.5) for each 3 comparisons. In Cox proportional harzard analysis, LV systolic function influenced the group 2 survival (odds ratio 3.8, 95% CI 1.7 to 8.3, p<0.005) and the group 3 survival (odds ratio 2.2, 95% CI 1.1 to 4.5, p<0.05). The cardiac event free survival was influenced by age(odds ratio 1.6, 95% CI 1.2 to 2.1, p<0.005) and LV systolic function(odds ratio 1.8, 95% CI 1.3 to 2.5, p<0.001). CONCLUSION: Younger female patients with AMI had a more favorable prognosis compared with older female patients. LV systolic fuction was important as a prognostic factor for long-term survival except younger female AMI patients.

Atrial tachycardia (AT) originating from the aortomitral junction is a very rare and challenging disease. Its arrhythmic characteristics have not been described in detail compared with the descriptions of the arrhythmic characteristics of AT originating from the other locations. Only a few case reports have documented successful ablation of this type of AT using transaortic or transseptal approaches. We describe a case with AT that was resistant to right-sided ablation near the His bundle failed and transaortic ablation at the aortomitral junction successfully eliminated.

BACKGROUND AND OBJECTIVES: Previous studies have demonstrated an association between several single nucleotide polymorphisms and atrial fibrillation (AF). We hypothesized that the phenotypes of AF patients were associated with common AF susceptibility alleles. SUBJECTS AND METHODS: A total of 659 patients (57±9 years, 76% male) with AF who underwent catheter ablation and 659 age, and sex-matched controls were genotyped for the common AF susceptibility alleles rs2200733 and rs6843082 at 4q25, rs2106261 at ZFHX3, and rs13376333 at KCNN3. The phenotypes of AF patients, including electroanatomical characteristics of the left atrium and recurrence after ablation, were compared. RESULTS: The rs2200733 variant allele carriers have larger left atrium volume (128.5±40.7 vs. 113.5±29.2 mL, p=0.020), longer PR interval (185.9±32.6 vs. 174.8±21.9 ms, p=0.018), and higher amplitude of negative P-wave terminal force in Lead V₁ (0.07±0.04 vs. 0.05±0.04 mV, p=0.015) on electrocardiography than those without the variant allele. When the patients were assigned to three groups according to the number of variant alleles (Group A: no variant, n=15; Group B: 1 variant, n=158; Group C: 2 variants, n=439), incremental prognostic value, according to the number of variant alleles, was demonstrated (Log Rank p=0.015). Multivariate Cox regression analysis showed that persistent AF (OR 1.677, 95% CI 1.176-2.381, p=0.004) and the number of variants (OR 1.552, 95% CI 1.099-2.222, p=0.015) were independent predictors for recurrence of AF. CONCLUSION: This study showed the common AF susceptibility alleles at 4q25 and ZFHX3 are associated with electroanatomical characteristics of the left atrium and the clinical outcomes of catheter ablation in Korean patients with AF.

Rhythm control therapy is the main strategy for restoring and maintaining sinus rhythm in patients with non-valvular atrial fibrillation (NVAF). Sinus rhythm is better restored and maintained with antiarrhythmic drugs than with placebo treatment. In addition, catheter ablation or combination therapy is more effective than antiarrhythmic drugs for treating NVAF. However, in most clinical trials to date, rhythm control therapy has resulted in neutral clinical outcomes compared with rate control therapy. The decision to undergo rhythm control therapy should be based on age, atrial fibrillation (AF)-related symptoms, type of AF, structural heart disease, and underlying comorbidities. For now, rhythm control therapy is indicated to improve symptoms in patients with NVAF who have refractory symptoms after adequate rate control therapy. The Korean Heart Rhythm Society organized the Korean AF Management Guideline Committee and analyzed all available data, including South Korean patients with NVAF. This review article provides general principles and detailed methodology for rhythm control therapy in South Korean patients with NVAF.

Rhythm control therapy is used in atrial fibrillation (AF) management to improve AF-related symptoms along with rate control. AF catheter ablation is effective in maintaining sinus rhythm and has an acceptable complication rate. Compared with antiarrhythmic drugs, AF catheter ablation is superior with respect to arrhythmia-free survival and improvement in the quality of life. Therefore, AF ablation is recommended for rhythm control after the failure of antiarrhythmic drugs and is sometimes considered a first-line therapy for AF patients. Radiofrequency and cryoballoon ablation show similar efficacy, with slightly different complication profiles. Surgery for AF is also an effective rhythm control therapy and should be considered in patients undergoing cardiac surgery or in those with failed catheter ablation. For patients undergoing AF catheter ablation, performing ablation under uninterrupted warfarin or non-vitamin K oral anticoagulant treatment is recommended for periprocedural stroke risk management. Here, we review existing data and discuss the general principles of AF catheter and surgical ablation in patients with AF.

PURPOSE: Previous studies have demonstrated an association between eNOS polymorphisms and atrial fibrillation (AF). We sought to determine whether eNOS polymorphisms are associated with AF recurrence after a radiofrequency catheter ablation (RFCA). MATERIALS AND METHODS: A total of 500 consecutive patients (56+/-11 years, 77% male) with paroxysmal (68%) or persistent (32%) AF who underwent RFCA and 500 age, gender-matched controls were genotyped for the eNOS3 single nucleotide polymorphism (rs1799983). AF recurrence was monitored according to 2012 ACC/AHA/ESC guidelines. RESULTS: The frequencies of the rs1799983 variant alleles (T) in the case and control group were not significantly different (OR 1.05, 95% CI 0.75-1.46, p=0.798). AF patients with rs1799983 variants were more likely to have coronary artery disease or stroke than those without genetic variant at this gene (31.0% vs. 17.3%, p=0.004). During mean 17 months follow-up, early recurrence of AF (ERAF; within 3 months) and clinical recurrence (CR) of AF were 31.8% and 24.8%, respectively. The rs1799983 variant was associated with higher risk of ERAF (OR 1.71, 95% CI 1.06-2.79, p=0.028), but not with CR. ERAF occurred earlier (11+/-16 days) in variant group than those without variant allele (20+/-25 days, p=0.016). A multiple logistic regression analysis showed that presence of the rs1799983 variant (OR 1.75, 95% CI 1.07-2.86, p=0.026) and persistent AF were independent predictors for ERAF after AF ablation. CONCLUSION: The rs1799983 variant of the eNOS3 gene was associated with ERAF, but not with CR, after RFCA. eNOS3 gene variants may have a potential role for stratification of post-ablation management.

BACKGROUND AND OBJECTIVES: Although the standard management of an abdominal aortic aneurysm (AAA) is surgery, endovascular stent-graft treatment is more attractive for patients with significant co-morbid conditions. We evaluated the immediate and mid-term outcomes for the endovascular treatment of AAA. SUBJECTS AND METHODS: Between November 1996 and August 2004, 59 patients with an AAA (53 males, mean age 68.0+/-9.6 years, 3 cases with ruptured AAA) underwent an endovascular stent-graft repair at our institute. All patients were evaluated by an angiography, taken just after the completion of the procedure and at followed up with computed tomography (CT) at 1, 3, 6 and 12 months, and yearly thereafter. RESULTS: Technical success was achieved in 54 of the 59 patients (91.5%). The periprocedural mortality rate was 3.4% (2 of the 59 patients). A primary endoleak was found in 12 patients (20.3%)(type I; 9 patients, type II; 2 patients, type III; 1 patient), 2 of which required subsequent surgical conversion. Spontaneous resolution of an endoleak was seen in 4 patients (33.3%). The average follow-up period of 57 patients was 27.5 months (range from 72 days to 2581 days). In 8 patients (14.0%), a newly developed secondary endoleak was documented. A total 14 patients (23.7%) died during the follow-up period (rupture; 3, operation-related sepsis; 3, unrelated causes; 3, cardiac arrest; 1, unknown causes; 4). The cumulative survival rates at 30 days and at 1 and 2 years were found to be 93.0, and 85.7 and 76.3%, respectively, using Kaplan-Meier methods. Secondary intervention was required in 12 patients (21.8%), and surgical conversion in 4 (6.8%), with 2 (3.4%) requiring conversion to open surgery immediately after the intervention. In those with technical success, without endoleaks and graft failure, the survival rate during follow-up was higher (97.1%; rate with the exception of unrelated cause of death) than that of all the patients. CONCLUSION: The immediate and mid-term results suggest that the endovascular treatment of an AAA is technically feasible and effective. There was higher mortality and morbidity in primary and newly developed endoleak cases; therefore, proper selection of cases, according to the anatomical and clinical criteria, is essential, with meticulous regular follow-ups being critical for the optimal endovascular treatment of an AAA.

BACKGROUND AND OBJECTIVE: Although the endovascular method of treating abdominal aortic aneurysms (AAA) shows good early results and benefits, the late outcome of this treatment remains uncertain. This study evaluated the late outcome following an endovascular AAA repair. SUBJECTS AND METHODS: Thirty-three patients that had undergone an endovascular AAA repair at our institute were evaluated. The results of the treatment were evaluated by an angiography, taken just after the completion of the procedure, and by contrast-enhanced CT scans at 1, 3, 6 and 12 months, and annually thereafter. RESULTS: The patient's characteristics were as follows: 29 (88%) were male, 19 (58%) had coronary artery disease and 7 (21%) had renal insufficiency. A technical success was achieved in 31 patients (94%), with primary endoleaks in two. Two patients (6.1%) died within 1 month of the procedure, both at an elderly age, with high risk. There was 1 (3%) incidence of early complications that required treatment. During the 28 month follow-up period, 6 patients (20%) needed a secondary procedure. Endoleaks remained in 4 patients, and the size of aneurysm increased in 3 patients. Four patients died during follow-up, and two had an endoleak. The cause of death was not related to cardiovascular diseases in the other two patients. The event free survival at 24 months was 72%. CONCLUSION: The late outcome after an endovascular AAA repair was favorable. However, a secondary procedure was needed, and endoleaks observed, in half of the patients that died during follow-up. Therefore, regular evaluation of aneurysms and the management of endoleaks are very important for a favorable late outcome in endovascular AAA repair patients.
