However, clinical and electrophysiological (EP) characteristics of patients with AVNRT whose tachycardia attacks could not be adequately controlled by antiarrhythmic agents have not been studied in a large patient cohort. We aimed to define the clinical and EP features of patients with drug-refractory AVNRT. Methods and results: A total of 266 consecutive patients with AVNRT undergoing catheter ablation after a period of medical treatment were analyzed: 144 patients with drug-refractory AVNRT (Group 1) and 122 patients with drug-responsive AVNRT (Group 2). Age was significantly higher (p = 0.027) and the presence of hypertension (p = 0.030), diabetes mellitus (p = 0.047), and valvular heart diseases (p = 0.008) was more frequent in Group 1 compared to Group 2. Among the EP features, atrial-His jump (81% vs 69%, p = 0.028) and atrial vulnerability (26% vs 14%, p = 0.018) were significantly higher, echo zone was significantly more long-lasting (44 ± 24 ms vs 38 ± 22 ms, p = 0.018), and tachycardia cycle length (TCL) was significantly longer (348 ± 41 ms vs 329 ± 38 ms, p = 0.000) in Group 1 than in Group 2. Multivariate analysis showed that hypertension (p = 0.036), valvular heart disease (p = 0.014), atrial vulnerability (p = 0.037), TCL (p = 0.003), and wide echo zone (p = 0.028) were independent predictors for drug-refractory AVNRT. Conclusion: In the presence of hypertension, valvular heart disease, atrial vulnerability, long-lasting echo zone, and relatively slow AVNRT, medical treatment is less likely to prevent the tachycardia episodes.

Therefore, identification of patients at risk for recurrence of AF after slow pathway ablation is important because of the necessity for additional therapies. The purpose of this study was to determine whether successful slow pathway ablation influences P wave parameters and whether these parameters predict the recurrence of paroxysmal AF in patients with both AVNRT and paroxysmal AF after ablation. Methods: Thirty-six patients with AVNRT and documented paroxysmal AF (Group 1) were compared to 36 age-matched controls with AVNRT only (Group 2). P wave durations and P dispersion were measured before and after ablation. Results: No significant differences were observed between P wave parameters observed before and after ablation. Maximum P wave durations (Pmax) and P dispersion (Pdisp) were significantly higher in Group 1 than in Group 2 (P < 0.001 for both) whereas minimum P wave durations did not differ between groups, both before and after ablation. Ten patients (28%) in Group-1 had recurrence of AF during a mean follow-up of 34 ± 11 months. Univariate predictors of AF recurrence were Pdisp ≥35.5 ms (P < 0.010), left atrial diameter >40 mm (P < 0.010), mitral or aortic calcification (P < 0.010), Pmax ≥112 ms (P < 0.050), valvular heart disease (P < 0.050), and atrial vulnerability (induction of AF lasting >30 second) after ablation (P < 0.050). However, only Pdisp ≥35.5 ms (P < 0.050) and left atrial diameter >40 mm (P < 0.010) were independent predictors of AF recurrences. Conclusion: This study suggests that P wave dispersion could identify patients with AVNRT susceptible to recurrence of AF after slow pathway ablation.

The major significance of this anomaly lies in its association with complex cardiac defects and the technical difficulty that can accompany cardiac catheterization. We report our experience with successful catheter ablation of a right posteroseptal concealed accessory pathway in a 6-year-old boy with infrahepatic interruption of the inferior vena cava and azygos continuation.

Introduction: Radiofrequency (RF) ablation of the slow pathway for treatment of atrioventricular ... more Introduction: Radiofrequency (RF) ablation of the slow pathway for treatment of atrioventricular nodal reentrant tachycardia (AVNRT) is conventionally performed during sinus rhythm. Aim: To evaluate the clinical and electrophysiological features and the short-and long-term results of slow pathway RF ablation during ongoing AVNRT. Material and methods: A total of 282 consecutive patients with AVNRT undergoing RF catheter ablation were analysed. Patients whose tachycardia episodes could not be controlled during RF energy application and who underwent slow pathway ablation or modification during ongoing tachycardia formed the study group (group 1, n = 16) and those ablated during sinus rhythm formed the control group (group 2, n = 266). Results: Of the clinical characteristics, only the frequency of tachycardia attacks was higher in group 1 (3.3 ±1.2 vs. 2.1 ±0.9 attacks/month, p < 0.001). Among the baseline electrophysiological measurements, the echo zone lasted significantly longer in group 1 than in group 2 (78 ±25 ms vs. 47 ±18 ms; p < 0.001). The immediate procedural success rate was 100% in both groups. There were no significant differences between groups regarding the mean number of radiofrequency energy applications (5.2 ±4.2 vs. 5.8 ±3.9), total procedure times (42.4 ±30.5 min vs. 40.2 ±29.4 min) and fluoroscopy times (11.4 ±8.5 min vs. 12.2 ±9.3 min) (p > 0.050 for all). All patients were followed-up for 29 ±7 months; only 2 patients (< 1%) in group 2 recurred (p > 0.050). No permanent atrioventricular block was observed. Conclusions: The RF catheter ablation or modification of the slow pathway during ongoing AVNRT is feasible with acceptable short-and long-term efficacy and safety. However, this approach needs to be clarified with large-scale studies.

Although a "final common pathway" connecting the slow and fast pathways to the proximal His bundle was thought to be part of the reentrant circuit, debate on the presence of an upper common pathway continues. We report a case of AVNRT continuing despite the occurrence of ventriculoatrial block, thus supporting the existence of an upper common pathway.

We present a 30-year-old woman with diffuse SVAS complicated with left ventricular apical aneurysm. We believe that subtle left ventricular myocardial ischemia or infarction and long-lasting severe pressure overload to the apical chamber caused LV apical aneurysm in our case. Acquired LV apical aneurysm secondary to supravalvular aortic stenosis, in the absence of atherosclerotic coronary artery disease and hypertrophic obstructive cardiomyopathy, has not been described before.

Therefore, it is important to assess non-invasively the risk of developing paroxysmal atrial fibrillation (PAF) in hypertensive patients during sinus rhythm. This study was undertaken to determine if hypertensive patients with history of PAF could be identified while in sinus rhythm by measurement of signal-averaged ECG P-wave duration. Methods: Signal-averaged electrocardiography (SAECG) P-wave recording was performed in 44 hypertensive patients (30 men and 14 women; mean age 60F11 years, group A) who had a history of paroxysmal AF and in 50 hypertensive patients without history of AF (33 men and 17 women; mean age 57F12, group B). All patients were also evaluated by using echocardiography to measure left ventricular ejection fraction (LVEF) and left atrial diameter (LAD). Results: SAECG P-wave duration was found to be significantly higher in group A than in group B (146F14 ms vs. 128F11 ms, pb0.001). Left atrial diameter was not significantly different (40.1F3.4 mm vs. 39.3F3.0 mm, pN0.05), whereas LVEF was significantly lower in group A than group B (63F5% vs. 67F4%, p=0.03). There was a correlation between SAECG P-wave duration and age (r=0.32, pb0.05). In univariate analysis, SAECG P-wave duration and LVEF were significant predictors of PAF, but only SAECG P-wave duration remained a significant independent predictor of PAF in multivariate analysis. Conclusion: The results of this study indicate that hypertensive patients with history of PAF can be detected while in sinus rhythm by signalaveraged ECG P-wave duration.

In this study, we evaluated whether echocardiographic SAT is related to insulin resistance and IMT in obese children. A total of 46 obese subjects (10.2+/-2.5 years of age, 25 male patients) and 30 age- and gender-matched lean subjects (10.8+/-3.1 years of age, 13 male patients) were included in this study. The criterion for diagnosing obesity was defined as the body mass index (BMI) being over 97% percentile of the same gender and age. Serum triglyceride (TG), low- and high-density lipoprotein, cholesterol, glucose and insulin levels were measured during the fasting state. Each subject underwent a transthoracic echocardiogram and the SAT thickness was measured during end-diastole from the parasternal long-axis views. The obese subjects had significantly higher SAT thickness and IMT values compared with the subjects in t...

Patients and methods: The study included 48 FMF patients (26 males, 22 females, mean age 11.10±3.42 years; range 5 to 18 years) as the FMF patients and 31 healthy children (17 males, 14 females, mean age 9.61±2.83 years; range 5 to 17 years) as the healthy controls. Electrocardiography and conventional echocardiography were performed on the FMF patients and healthy controls. Both groups were evaluated with a standard 12-lead electrocardiography. QT, JT and RR distances were measured in both groups. The corrected QT (QTc) and corrected JT (JTc) were calculated. QTcd and corrected JT dispersion (JTcd) were detected. Results: There was no statistically significant difference between the FMF patients and healthy controls in terms of RR, QT, QTd, QTcd, JT, JTc, JTd, and JTcd measurements and echocardiography parameters. QTc value was higher in the FMF patients than the healthy controls. Conclusion: QTc value indicates increased ventricular sensitivity and is an important marker of cardiovascular mortality. It has an important effect on sudden cardiac death and arrhythmia. Our study results suggest that electrocardiographic monitoring may be useful in patients with FMF.
