Aims: Intracardiac echocardiography (ICE) is a relatively young technique used during complex electrophysiology proce-dures, such as atrial fibrillation (AF) ablation. The aim of this study was to assess whether the use of ICE modifies the radia-tion exposure at the beginning of the learning curve in AF ablation. Materials and methods: In this retrospective study, 52 patients, in which catheter ablation for paroxysmal or persistent AF was performed, were included. For 26 patients we used ICE guidance together with fluoroscopy, whereas for the remaining 26 patients we used fluoroscopy alone, all supported by electroanatomical mapping. We compared total procedure time and radiation exposure, including fluoroscopy dose and time between the two groups and along the learning curve. Results: Most of the patients included were suffering from paroxysmal AF (40, 76%), pulmonary vein isolation being performed in all patients, without secondary ablation sites. The use of ICE was associated with a lower fluoroscopy dose (11839.60±6100.6 vs. 16260.43±8264.5 mGy, p=0.041) and time (28.00±12.5 vs. 42.93±12.7 minutes, p=0.001), whereas the mean procedure time was similar between the two groups (181.54±50.3 vs 197.31±49.8 minutes, p=0.348). Radiation exposure was lower in the last 9 months compared to the first 9 months of the study (p<0.01), decreasing gradually along the learning curve. Conclusions: The use of ICE lowers radiation exposure in AF catheter ablation from the beginning of the learning curve, without any difference in terms of acute safety or efficacy. Aware-ness towards closest to zero radiation exposure during electrophysiology procedures should increase in order to achieve better protection for both patient and medical staff.

Background and Purpose: In Romania, robust data about the prevalence of obesity and heart failure are lacking, especially in the elderly; therefore, this study aims to analyze the profile of overweight and obese patients aged >65 years admitted to a Romanian hospital for worsening heart failure, and also their risk in the presence of comorbidities. Patients and Methods: This cross-sectional study was conducted in 126 consecutive elderly patients with overweight and obesity admitted to a Romanian hospital for worsening heart failure. They were divided into three groups: with reduced (<40%)-HFrEF, mid-range (40-49%)-HFmrEF and preserved (≥50%) ejection fraction-HFpEF. Obesity was defined according to the body mass index (BMI) status: obesity, ≥30 kg/m 2 ; overweight, 25-29.9 kg/ m 2. The Charlson Comorbidity Index (CCI) was calculated to evaluate the severity of comorbidity, with a score ranging from 2 (only heart failure present and age >65 years) to 30 (extensive comorbidity). Results: NT-proBNP values are negatively correlated with BMI only in patients with HFpEF. Creatinine clearance (p=0.0166), the presence of atrial fibrillation (p=0.0095) and NYHA functional class were independent predictors of increased NT-proBNP values. CCI score is negatively correlated with NT-proBNP values in patients with HFmrEF (r= −0.448, p=0.009) and HFpEF (r= −0.273, p=0.043). The CCI risk was not significantly different between the three groups. Conclusion: Elderly heart failure patients with overweight or obesity have particular characteristics in terms of NT-proBNP values and presence of comorbidities. In the studied population, NT-proBNP levels were strongly influenced by renal function, NYHA functional class, the presence of atrial fibrillation and left ventricular ejection fraction.

Heart failure is currently a real public health problem due to the extremely high morbidity and mortality of this disease. In this context, cardiovascular prevention measures should be implemented as early as possible. In addition to classic prevention measures, a number of extremely important specific recommendations should be considered: informing patients about their underlying disease, identifying the cardiovascular and non-cardiovascular factors that have led to cardiac decompensation, reducing daily salt consumption, monitoring body weight, forbidding smoking and recreational substances, conducting a regular exercise program under supervision, and increasing adherence to treatment.
