    Mid-Term Results of Patients with Transposition of Great Arteries Who Underwent Senning Procedure
    (2014) Gursu, Hazim Alper; Varan, Birgul; Ozkan, Murat; Tokel, Kursat; Erdogan, Ilkay; https://orcid.org/0000-0002-0707-2678; https://orcid.org/0000-0002-6719-8563; https://orcid.org/0000-0002-6759-1795; https://orcid.org/0000-0001-6887-3033; AHI-4502-2022; ABB-1767-2021; AAF-3253-2021; ABB-2220-2021
    Background: This study aims to evaluate mid-term follow-up results for patients with transposition of great arteries to whom Senning procedure was performed. Methods: Files of 95 child patients (63 boys, 22 girls; mean age 15.2 +/- 23.9 months; range 1 month to 12.5 years), who were diagnosed with transposition of great arteries and underwent atrial switch operation in our institute, were retrospectively evaluated. In the follow-ups; physical examination, electrocardiography, and echocardiography were performed. In addition, ambulatory electrocardiography monitorization was conducted on 25 patients. Results: Out of 95 patients who were performed atrial switch operation, 10 died in the postoperative period. The mean follow-up period was 33.4 +/- 43.7 months (1-16 years; mean 18 months). During the follow-ups, arrhythmia was detected in 25.8% of the patients, stenosis of pulmonary venous baffle was detected in 21.2%, systolic dysfunction of the right ventricle was detected in 19%, severe tricuspid valve insufficiency was detected in 18.9%, and baffle leak was detected in 15.3%. Of the patients, 11.7% were operated a second time, and 8.2% were reoperated due to stenosis of pulmonary venous baffle. Conclusion: Short and mid-term results of Senning procedure are not satisfactory. Patients should be monitored for possible right ventricle dysfunction, arrhythmia, systemic valve insufficiency, and stenosis of the tunnel.

    Assessment of Atrial Fibrillation and Ventricular Arrhythmia Risk after Bariatric Surgery by P Wave/QT Interval Dispersion

    The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented. The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals. In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined. The patients were followed 1 year. PWD and CQTD values before and 3rd, 6th, and 12th months after the surgery were calculated and compared. There was a statistically significant decline in body mass index (BMI), PWD, and CQTD values among baseline, 3rd, 6th, and 12th months (p < 0.001 for all comparisons). Correlation analysis showed a statistically significant correlation between Delta PWD and Delta BMI (r = 0.719, p < 0.001), Delta PWD and Delta left ventricular end-diastolic diameter (LVEDD) (r = 0.291, p = 0.002), Delta PWD and Delta left atrial diameter (LAD) (r = 0.65, p < 0.001), Delta CQTD and Delta BMI (r = 0.266, p = 0.004), Delta CQTD and Delta LVEDD (r = 0.35, p < 0.001), Delta CQTD and Delta LAD (r = 0.289, p = 0.002). In multiple linear regression analysis, there was a statistically significant relationship between Delta PWD and Delta BMI (beta = 0.713, p < 0.001), Delta PWD and Delta LVEDD (beta = 0.174, p = 0.016), Delta PWD and Delta LAD (beta = 0.619, p < 0.001), Delta CQTD and Delta BMI (beta = 0.247, p = 0.011), Delta CQTD and Delta LVEDD (beta = 0.304, p < 0.001), Delta CQTD and Delta LAD (beta = 0.235, p = 0.009). PWD and CQTD values of patients were shown to be attenuated after bariatric surgery. These results indirectly offer that there may be a reduction in risk of AF, ventricular arrhythmia, and sudden cardiac death after obesity surgery.

    The Effect of Sumatriptan in lschemic Conditions in the Rat Heart
    (2018) Altunkaynak Camca, Hande Ozge; Tecder Unal, Muge; Tuncer, Meral; 32454677
    Objectives: The aim of this study was to investigate the effect of SUM on IR-induced injury in rat heart and its effect on IPC-induced protection. Materials and Methods: The rats were randomly divided into four groups: IR, SUM-IR, IPC, and SUM-IPC. The mean arterial blood pressure and heart rate were recorded to calculate PRP. Standard limb lead 2 ECG were recorded to evaluate arrhythmia parameters. Results: The PRP values in the SUM-IPC group were significantly lower than in the SUM-IR group at the beginning of reperfusion (p<0.05). The incidence of VT in the IPC, SUM-IR, and SUM-IPC groups was significantly lower than in the IR group (p<0.05). VF was only observed in the IR group. Conclusion: SUM protects the heart against IR injury but is not as protective as IPC alone. Although SUM diminishes IPC-induced protection against VT, the preventive effect of SUM against VF may be predictive for cardioprotection in ischemic conditions.
