Long QT syndrome (LQTS) is an inherited primary arrhythmia syndrome associated with life-threatening ventricular arrhythmias and sudden death. This study aimed to report the clinical and genetic characteristics and outcomes of children diagnosed as having LQTS in a tertiary pediatric cardiology center in Turkey.

This was a retrospective review of pediatric patients diagnosed as having LQTS at our center from January 2011 to April 2020.

A total of 145 patients (76 males) were included, with a mean age of 9.2±4.5 years and a mean weight of 35.7±18.5 kg; 38 (26.2%) were identified as having LQTS during family screening, whereas a significant proportion of patients were asymptomatic at presentation, 15 patients (10.3%) were diagnosed after previous cardiac arrest, and 26 patients (18%) had syncope. The mean Schwartz score was 4.5 points (range, 3-7.5 points). Furthermore, 107 patients (82%) were confirmed to have a pathogenic mutation for LQTS genes. All patients received beta-blockers. Implantable cardioverter-defibrillator insertion was performed in 34 patients (23.4%). Left or bilateral cardiac sympathetic denervation was performed in 9 patients (6.2%). Median follow-up time was 35.6±25.8 months. Five (3.4%) patients died during the follow-up. Statistical analyses of risk factors for major cardiac events revealed that the QTc was >500 ms and that T wave alternans, high Schwartz score, and Jervell and Lange-Nielsen syndrome were strong and significant predictors of cardiac events.

LQTS has a variety of clinical manifestations. Patients' symptoms ranged between asymptomatic and sudden cardiac death (SCD). By raising the awareness of physicians regarding the disease, SCD might be prevented in the early period.

The aim of the study was to evaluate the DNA and chromosomal damage in peripheral blood lymphocytes (PBLs) of patients with acute coronary syndrome (ACS) and to explore the effect of coronary angiographies in these patients.

The study included ACS patients who underwent a coronary angiography (CAG) and healthy controls. The ACS sample was divided into two groups patients with unstable angina pectoris (UAP) and acute myocardial infarction (AMI). The frequency of DNA damage [expressed as genetic damage index (GDI)] was analyzed using the comet assay pre- and post-CAG. Chromosomal aberrations were measured as micronuclei (MNs) frequency using the cytokinesis-block MN (CBMN) assay. Additionally, detailed anamnestic data were taken from the each patient.

Increased levels of DNA and chromosomal damage have been revealed in ACS patients compared to the healthy controls. GDI values were also significantly higher in AMI patients than in UAP patients. A highly significant increase of DNA damage was also observed in all patients post-CAG. There was significantly higher MN frequency and significantly lower nuclear division index (NDI) in AMI patients than in UAP patients' pre-CAG. After CAG, there was no significant difference in MN frequencies and NDI values between UAP and AMI patients.

Correlated with disease severity, our results showed that AMI patients have higher levels of both DNA and chromosomal damage in PBLs compared to UAP patients. The increased level of genome instability was especially evident post-CAG compared to the observed damage pre-CAG.

We aimed to evaluate the incidence of organ cysts in patients with type A aortic dissection (TAAD) to assess the association between organ cysts and TAAD.

Between January 2018 and December 2018, all patients with TAAD undergoing aortic surgery at our center were enrolled into the study; patients undergoing isolated coronary artery bypass grafting at our center were selected as the control group. selleck chemicals Baseline differences between the 2 groups were adjusted using propensity-score matching. The incidence of organ cysts was compared between the 2 groups in total and matched cohorts.

We enrolled 290 patients with TAAD and 293 patients with coronary artery disease (control group). The incidence of all organ cysts, liver cysts, renal cysts, and other organ cysts, was significantly higher in the TAAD group than in the control group (50.0% vs. 35.5%, p<0.001; 24.5% vs. 10.2%, p<0.001; 33.4% vs. 24.9%, p=0.023; and 6.2% vs. 1.5%, p=0.005; respectively). Among the 191 propensity score-matched patient pairs, the incidence of organ cysts, liver cysts, renal cysts, and other organ cysts was also significantly higher in the TAAD group than in the control group (57.6% vs. 30.9%, p<0.001; 28.8% vs. 11.0%, p<0.001; 39.3% vs. 19.9%, p<0.001; and 8.4% vs. 1.0%, p=0.001; respectively). The incidence of cysts with single-organ and multiple-organ involvement was also significantly higher in the TAAD group than in the control group (34.0% vs. 20.4%, p=0.003; and 23.6% vs. 10.5%, p=0.001).

Our results show a higher incidence of organ cysts in patients with TAAD which is indicative of a common pathogenetic pathway between organ cysts and aortic dissection.

Although the effect of coronary revascularization on clinical outcomes before and after transcatheter valve implantation (TAVI) is debatable, there is currently insufficient data to determine the most appropriate revascularization strategy. In this study, we present our single-center experience of percutaneous coronary intervention (PCI) and its effect on clinical outcomes and mortality in patients undergoing TAVI.

We performed a retrospective analysis of 526 consecutive patients at our center, and 127 patients with obstructive coronary artery disease were included in the study. Patients were divided into two groups the revascularization group (group 1) and the non-revascularization group (group 2). Procedural complications and long-term all-cause mortality rates were compared between the two groups.

Of the 526 patients, group 1 comprised 65 patients (12.3%) who underwent PCI, and group 2 comprised 62 patients (11.7%) who did not undergo revascularization. According to Valve Academic Research Consortium 2 criteria, post-procedural complications, including pericardial effusion, stroke, major vascular complications, major bleeding, and emerging arrhythmias, were similar between the groups.
