Objective: Atrial High Rate Episodes (AHRE) are subclinical atrial tachyarrhythmias detectable by cardiac implantable electronic devices (CIEDs). AHREs have been associated with an increased risk of developing atrial fibrillation (AF), thromboembolism, cardiovascular and cerebrovascular events, and mortality. Although recent studies have assessed the value of oxidative stress markers in patients with AF, the relationships between AHRE and oxidative stress markers, including nitric oxide, has not yet been elucidated. This study aims to investigate the relationship between these markers and AHRE.

Method: This prospective, cross-sectional study comprised 180 patients with CIEDs. The study population was divided into two groups based on the presence (n = 78) and absense (n = 102) of AHRE to analyze its association with biomarkers.

Results: The AHRE (+) group was significantly older, had a higher prevalence of hypertension, higher NT-proBNP (508.8 ± 249 pg/mL vs. 415.3 ± 292.1; P = 0.037), MDA levels (20.9 ± 4.1 μmol/L vs. 19.1 ± 3.1 μmol/L; P = 0.006), and iNOS activity (1,935.9 ± 326.1 pg/mL vs. 1,677.4 ± 363.2 pg/mL; P < 0.001). Logistic regression analysis identified age, hypertension, MDA (odds ratio [OR]: 1.131, 95%CI: 1.009 - 1.268, P = 0.035), inducible nitric oxide synthase (iNOS) activity (OR = 1.002, 95% CI = 1.001 - 1.003, P < 0.001), and endothelial nitric oxide synthase (eNOS) activity (OR = 0.990, 95% CI = 0.986 - 0.984, P < 0.001) as independent predictors of AHRE.

Conclusion: The study findings indicated that plasma levels of NT-proBNP, MDA, nitric oxide, and the expression of iNOS and eNOS were significantly associated with AHRE. Moreover, elevated plasma MDA concentrations, increased iNOS activity, and decreased eNOS activity were identified as independent predictors of AHRE.

Objective: Aortic rupture is a rare and catastrophic emergency. Prompt diagnosis and treatment are the primary determinants of mortality. During follow-up, the majority of patients who have been effectively treated die from hypovolemic shock and multiorgan failure. This article describes the clinical and procedural details of sixteen patients with ruptured aortic aneurysms treated endovascularly. In addition, it discusses the main factors contributing to the mortality of these patients.

Method: Patients who underwent endovascular treatment for acute aortic rupture at our center from October 2016 to March 2023 were included in this retrospective study.

Results: A total of 16 patients underwent endovascular aneurysm repair (EVAR) or thoracic endovascular aneurysm repair (TEVAR) for acute aortic rupture. The patients’ mean age was 73.06 years (range: 52-92), and 15 of them were male. The ruptures occurred in the abdominal aortic aneurysm in ten patients, in thoracic aortic aneurysm in three patients, in the isolated iliac artery aneurysm in two patients, and there was one case of non-aneurysmal aortic rupture. In our series, patients who presented with an impending, self-limited rupture and stable hemodynamic status had good prognostic outcomes. However, eight patients died due to multiorgan failure, hemorrhagic shock, disseminated intravascular coagulopathy, renal failure, or abdominal compartment syndrome. These patients generally had poor admission vital signs and low hemoglobin values. The most critical determinants for the success of the procedure are promptly stopping the bleeding, avoiding general anesthesia, and opting for blood product replacement instead of fluid replacement.

Conclusion: Each patient with ruptured aortic aneurysm should be managed according to the patient’s hemodynamics at presentation, the size of the aneurysm, the suitability for percutaneous procedure, logistical factors, and the operator-center’s experience.

Objective: Heart failure (HF) often impacts liver function due to reduced cardiac output and increased venous congestion. The Albumin-Bilirubin (ALBI) score has recently been shown to possess prognostic value in patients hospitalized with HF. In this study, we aimed to evaluate the association of the ALBI score with long-term mortality in ambulatory HF patients with reduced ejection fraction (HFrEF).

Method: Consecutive patients with HFrEF were included between 2014 and 2019. The ALBI score was calculated using the following formula: (log10 total bilirubin [mg/dL] × 0.66) + (albumin [g/dL] × -0.085). Patients were categorized into two groups: low ALBI (≤ -2.60) and high ALBI score (> -2.60). The endpoint was all-cause mortality. Patients were followed up for a median of 55 (42.6-68.4) months.

Results: A total of 417 patients were included in the study. The mean age of the group was 51.5 ± 11.9 years, 74.8% were male, and 36.5% (n = 152) of the patients were in the high ALBI score group. Patients with a high ALBI score were more likely to be in the New York Heart Association functional class III/IV. These patients had significantly higher N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, systolic pulmonary arterial pressure, and inferior vena cava diameter, along with worse right ventricular systolic function than patients with a low ALBI score. All-cause mortality was significantly increased in the high ALBI score group (41.4% vs. 27.2%, P = 0.003). Multivariate analysis revealed the ALBI score (HR 1.53, 95% CI 1.09-2.15, P = 0.02) as an independent predictor of long-term mortality.

Conclusion: The ALBI score is associated with increased long-term mortality in outpatients with HFrEF. It can easily be evaluated and utilized as a liver dysfunction score in this patient group, providing prognostic information.

Objective: Atrial mechanical dysfunction may be an alternative mechanism underlying the increased risk of systemic embolism in patients with atrial septal aneurysm (ASA). This study aimed to evaluate left atrial (LA) and right atrial (RA) function using two-dimensional speckle tracking echocardiography (2D STE) in patients with isolated ASA.

Method: Fifty-four patients with ASA (mean age 50.3 ± 12.48, 37% male) and 48 healthy individuals of similar age and gender (mean age 48.3 ± 10.84, 39.6% male) were included in the study. To assess atrial mechanical function, measurements of left and right atrial reservoir strain (RS), peak contraction strain (PCS), and conduit strain (CS) were conducted using 2D STE, in addition to conventional evaluation with transthoracic echocardiography.

Results: LA RS and PCS values were significantly lower in the ASA group than in the controls (37.52 ± 2.89 vs. 40.16 ± 2.68%, P < 0.001 and 17.29 ± 2.5 vs. 19.18 ± 2.23%, P < 0.001, respectively). Similarly, RA RS and RA PCS were significantly lower in patients with ASA (36.97 ± 2.19 vs. 39.77 ± 2.36%, P < 0.001 and 16.78 ± 2.10 vs. 18.54 ± 2.43%, P < 0.001, respectively). A multivariate regression analysis revealed a strong independent association between ASA and the measures LA RS, LA PCS, RA RS, and RA PCS.

Conclusion: Our findings indicate that bi-atrial function are diminished in patients with isolated ASA. This may be a possible cause for the increased risk of arterial embolism in this patient group, aside from atrial arrhythmias and patent foramen ovale. Validating these results with larger studies may influence the treatment and follow-up strategies for patients with isolated ASA.

Objective: The metabolic equivalent (MET) and Synergy between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery (SYNTAX) score are two parameters with known cardiovascular prognostic significance. In this study, we aimed to investigate the direct relationship between MET and SYNTAX score in patients with chronic coronary syndrome (CCS).

Method: This retrospective study included 200 patients over 18 years of age who underwent coronary angiography and had a positive exercise electrocardiography test result. Patients were divided into two groups: Group 1 with a low SYNTAX score and Group 2 with a medium-high SYNTAX score. MET values were then compared between these groups.

Results: Baseline demographic characteristics and laboratory values were similar between the groups. The mean MET values in the low and medium-high SYNTAX score groups were 9.36 ± 2.38 and 8.78 ± 2.43, respectively. No statistical difference was observed (P = 0.086). Additionally, there was no statistical difference between the two groups in terms of MET values being 10 ≤ or 10 > (P = 0.172).

Conclusion: The main conclusion of our study is that there is no correlation between the SYNTAX score and functional MET value in CCS.

Objective: Deciding on the optimal duration of dual antiplatelet treatment (DAPT) remains a complex decision. This survey aims to explore the preferences for antiplatelet therapy and the daily routine regarding DAPT duration in coronary artery disease among a group of cardiologists in Türkiye.

Method: Using an online questionnaire with 38 questions, the preferences of 314 cardiologists were collected. Qualitative descriptive characteristics of the answers received from the participants were examined.

Results: Participating cardiologists mostly worked in training and research hospitals (51.59%) and university hospitals (21.66%). Participants primarily favored ticagrelor in patients undergoing PCI with a diagnosis of STEMI and NSTE-ACS (69.75% and 55.73% respectively). Clopidogrel was the most preferred P2Y12 treatment in patients with chronic coronary syndrome (CCS) after PCI (94.90%). Pre-treatment with a loading dose of a P2Y12 receptor inhibitor was administered to 57.01% of patients with NSTE-ACS, irrespective of the planned treatment strategy. In NSTE-ACS patients with low bleeding risk treated with PCI, 83.12% of participants recommended DAPT for 12 months and 14.65% for >12 months. In high-bleeding-risk NSTE-ACS patients treated with PCI, DAPT durations of six months (74.52%), three months (19.75%), and one month (5.73%) were chosen. Among CCS patients treated with PCI without an increased risk of bleeding, 12 months of DAPT was preferred by 68.15% of participants. Most participants (70.70%) were switching to a more potent P2Y12 receptor inhibitor therapy in emergency department clopidogrel-loaded patients with ACS.

Conclusion: The aim of this survey to capture a snapshot of the preferences of a group of cardiologists in Türkiye regarding DAPT treatment and duration. The responses were both in accordance and in conflict with the current guidelines.

Hypertension is a common public health issue, and its incidene increases parallel to age. It is inevitable that certain occupational conditions may pose risks for high blood pressure or cause difficulties in managing blood pressure. Working under specific circumstances may compromise the safety of individuals with hypertension and potentially others. Therefore, it is crucial to implement activities that enhance awareness of hypertension, to ensure regular periodic examinations, and to establish necessary precautions in the workplace for the health of employees and the public. Given the limited resources offering guidance on hypertension in the context of occupational health, the authors of this paper, who hail from different disciplines, have prepared a set of consensus-based suggestions.

A 45-year-old female patient was admitted to the emergency department with syncope. Her medical history revealed a diagnosis of Familial Partial Lipodystrophy 2 (FPLD2). The patient’s electrocardiogram showed a complete atrioventricular (A-V) block, and she had a history of insulin-dependent diabetes mellitus and coronary artery bypass surgery. A severe stenosis was observed in the aortic right coronary artery saphenous vein graft during coronary angiography, which was successfully revascularized. Subsequently, due to persistant syncope attacks, a permanent pacemaker was implanted after an electrophysiological study. This case highlights that serious cardiac conduction defects in patients with FPLD2 may not only be related to coronary artery disease but can also present as direct conduction defects.

Amyloidosis is a pathology that occurs as a result of the accumulation of various misfolded proteins in the extracellular space. It is a significant cause of morbidity and mortality due to multi-organ involvement. One of the most important determinants of mortality and morbidity is cardiac involvement. Cardiac amyloidosis (CA) may present with a variety of clinical findings. In this article, we aim to demonstrate the supportive role of cardiac and extra-cardiac tissue in the routine diagnostic pathway for CA.

Transcatheter closure of muscular ventricular septal defects (VSD) remains a safe and effective method with low complication rates. However, device migration can pose a significant challenge to interventional cardiologists due to potential mortal consequences. A 21-year-old female presented to our clinic with exertional dyspnea and was diagnosed with a muscular VSD. The defect was percutaneously closed using an Amplatzer occluder device. On the first post-procedural day, the patient experienced repeated episodes of coughing and mild hemoptysis. Imaging revealed migration of the VSD occluder device to the right pulmonary artery (PA). Percutaneous retrieval of the device was then decided upon. The right PA was accessed using a hydrophilic guidewire and a pigtail catheter. This catheter was exchanged for an 8-Fr sheathless guide catheter, and a 6-Fr Judkins right catheter was advanced into the right PA through the sheathless guide catheter using the mother-and-child technique. Multiple attempts using a snare were made to retrieve the migrated device. Eventually, the proximal marker point, the hub of the device, was grasped and pulled back from the PA, then externalized through the sheath without the need for surgical cutdown. Our report represents a case of complete percutaneous retrieval of an embolized VSD occluder device from the PA.
