Evaluation of risk factors for long-term atrial fibrillation development in patients undergoing typical atrial flutter ablation: a multicenter pilot study.

Background: Atrial flutter (AFL) and atrial fibrillation (AF) are the most commonly detected supraventricular arrhythmias and share similar pathophysiological mechanisms. After the successful ablation of AFL, AF frequently occurs in the long-term follow-up. As emphasized in some studies, certain mechanisms seem to predispose to the development of AF in AFL patients, and approximately 20% of these patients have accompanying AFL.

The Mean Corrected TIMI Frame Count Could Predict Major Adverse Cardiovascular Events in Patients with Coronary Slow-Flow Phenomenon.

Objective: The aim of the present study was to investigate the association between the mean corrected thrombolysis in myocardial frame count and major adverse cardiovascular events in patients with the coronary slow-flow phenomenon.

Methods: A total of 98 patients with coronary slow-flow phenomenon who met inclusion cri- teria from 2015 to 2020 were retrospectively included in the analysis. The patients were ranked according to their mean corrected thrombolysis in myocardial frame count values and were divided into quartiles based on those.

Systemic Venous Reconstructions During Pediatric Heart Transplantation.

Background: Congenital heart disease continues to be an important indication for pediatric heart transplantation (HT) and is often complicated by systemic venous anomalies. The need for reconstruction, surgical technique used, as well as the outcomes of these have limited documentation.

Methods: Descriptive, retrospective study of patients transplanted at Emory University between 2006 and 2017.

Pulmonary valve replacement in patients with repaired tetralogy of Fallot: early results for recovery of right ventricular dilatation and QRS duration.

Background/aim: Although pulmonary valve replacement (PVR) improves ventricular function and symptoms, the benefit and optimal timing of PVR are controversial. This study aimed to evaluate early response to PVR for right ventricle (RV) dilatation and QRS duration.

Materials And Methods: Retrospective analysis was performed for 32 patients with repaired tetralogy of Fallot (TOF) between March 2005 and October 2017.

The Relationship Between Sepsis-induced Immunosuppression and Serum Toll-like Receptor 9 Level.

Background/aim: Our aim was to determine serum TLR-9 levels in sepsis and evaluate the relationship between sepsis and serum TLR-9 levels.

Materials And Methods: The study group consisted of 80 consecutive patients with sepsis and 100 healthy individuals. The demographic characteristics, co-morbidities and hemodynamic data of all patients were recorded.

Correction of dilutional anemia induces renal dysfunction in diabetic patients undergoing coronary artery bypass grafting: a consequence of microcirculatory alterations?

Background: In this study we aimed to evaluate the effects of dilutional anemia resulting from cardiopulmonary bypass (CPB) and its correction with red blood cell (RBC) transfusion on tissue oxygenation and renal function in diabetic patients undergoing coronary artery bypass grafting (CABG).

Method: 70 diabetic patients who underwent elective CABG and whose hematocrit values had been between 24-28% at any time during CBP were prospectively randomized and equally allocated to two groups: patients who received RBC during CPB (group I, n = 35) vs. did not receive RBC during CPB (group II, n = 35).

Coexisting bicuspid aortic and pulmonary valves with normally related great vessels diagnosed by live/real time three-dimensional transesophageal echocardiography.

Coexistence of bicuspid aortic and pulmonary valves in the same patient is a very rare entity identified mainly during surgery and postmortem. To the best of our knowledge, only one case has been diagnosed by two-dimensional echocardiography in a newborn with malposition of the great arteries but no images were presented. Here, we are reporting the first case of bicuspid pulmonary and aortic valves diagnosed by live/real time three-dimensional transesophageal echocardiography in an adult with normally related great arteries.

Surgical treatment of infective valve endocarditis in children with congenital heart disease.

Objective: This study assesses surgical procedures, operative outcome, and early and intermediate-term results of infective valve endocarditis in children with congenital heart disease.

Methods: Seven consecutive children (five females, two males; mean age, 10.8 years) who underwent surgery for infective valve endocarditis between 2006 and 2010 were included in the study.

Randomized comparison between mild and moderate hypothermic cardiopulmonary bypass for neonatal arterial switch operation.

Objectives: To compare neonates receiving arterial switch operation (ASO) either with mild or moderate hypothermic cardiopulmonary bypass.

Methods: Forty neonates undergoing ASO were randomized to receive either mild (Mi > 32 °C, n = 20) or moderate (Mo > 26 °C, n = 20) hypothermic cardiopulmonary bypass (CPB) between April 2007 and June 2010. All patients were diagnosed with simple transposition of the great arteries.
