Abstract
AIMS Little is known about dynamic changes of the left atrial (LA) substrate over time in patients with atrial fibrillation (AF). This study aims to evaluate substrate changes following pulmonary vein isolation (PVI). METHODS AND RESULTS In our prospective observational study, consecutive patients undergoing first PVI-only and redo ablation were included. High-density maps of the two procedures were compared. Progression or regression was diagnosed if a significant concordant decrease or increase in bipolar voltages in ≥2 segments was observed, respectively. In 28 patients (61.2 ± 9.5 years, 39% female, 53.5% persistent AF), 111.013 voltage points from 56 high-density LA maps (1.982 points/patient) were analysed. Comparing the high-density maps of the first and second procedures, in the progression group (17 patients, 61%), there was a decrease in global (-35%, P < 0.001) and all regional voltages. In the regression group (11 patients, 39%), there was an increase in global (+43%, P < 0.001) and regional voltages. Comparing the progression with the regression group, the area of low-voltage zone (LVZ) increased (+3.5 vs. -4.5 cm2, P < 0.001) and LA activation time prolonged (+8.0 vs. -9.1 ms, P = 0.005). Baseline clinical parameters did not predict progression or regression. In patients with substrate progression, pulmonary veins (PVs) were more frequently isolated (P = 0.02) and the AF pattern at recurrence was more frequently persistent (P = 0.005). CONCLUSION Our study describes bidirectional dynamic properties of the LA substrate with concordant either progressive or regressive changes. Regression occurs with reduced AF burden after the first procedure, while progression is associated with persistent AF recurrence despite durable PV isolation. The dynamic nature of LA substrate poses questions about LVZ-based ablation strategies.

Abstract
Gender-related differences have been reported in patients who underwent pulmonary vein isolation (PVI). Atrial substrate plays a role in the outcomes after ablation but gender-related differences in atrial substrate have never been described in detail. We sought to analyze gender-related differences in atrial remodeling (spontaneous low-voltage zones [LVZs]) and their clinical relevance after PVI. We conducted a prospective multicenter study, including consecutive patients who underwent first PVI-only atrial fibrillation (AF) ablation. LVZs were analyzed on high-density electroanatomical maps collected with multipolar catheter, before PVI. In total, 262 patients (61 ± 11 years, 31% female, 50% persistent AF) were followed for 28 months. In women, LVZs were larger (10% vs 4% of left atrial surface [p <0.001]) and female gender was independently associated with fourfold higher risk of having advanced (LVZ > 15%) atrial remodeling (odds ratio 4.56, p <0.001). AF recurrence-free survival was not different between men and women (log-rank p = 0.2). Although LVZs were independently associated higher AF recurrences at multivariate analysis (hazard ratio [HR] 1.2, p = 0.038), female gender was not (HR 1.4, p = 0.211). Specifically, the LVZ cutoff to predict outcomes was different in men and women: >5% in men (HR 3.0, p <0.001), >15% in women (HR 2.7, p = 0.02). In conclusion, women have more widespread LVZ in all left atrial regions. Despite more extensive atrial remodeling, the AF recurrence rate is similar in men and women, and LVZs become prognostic in women only at high burden (>15%). LVZs seem to have a different prognostic role in men and women.

Abstract
BACKGROUND Left bundle branch area (LBBA) pacing is a promising pacing technique. LBBA implantable cardioverter-defibrillator (ICD) lead implantation reduces the number of leads in patients with both pacing and ICD indications, reducing cost and potentially increasing safety. LBBA positioning of ICD leads has not previously been described. OBJECTIVES The goal of this study was to evaluate the safety and feasibility of implanting an LBBA ICD lead. METHODS This prospective, single-center, feasibility study was conducted in patients with an ICD indication. LBBA ICD lead implantation was attempted. Acute pacing parameters and paced electrocardiography data were collected, and defibrillation testing was performed. RESULTS LBBA defibrillator (LBBAD) implantation was attempted in 5 patients (mean age 57 ± 16.5 years; 20% female) and achieved in 3 (60%). Mean procedural and fluoroscopy duration were 170.0 ± 17.3 minutes and 28.8 ± 16.1 minutes, respectively. Left bundle capture was achieved in 2 patients (66%) and left septal capture in 1 patient. LBBA pacing exhibited a mean QRS duration and V6 R-wave peak time of 121.3 ± 8.3 milliseconds and 86.1 ± 10.0 milliseconds. In all 3 patients, defibrillation testing was successful with mean time to adequate shock delivery of 8.6 ± 2.6 seconds. Acute LBBA pacing threshold and R-wave amplitudes were 0.80 ± 0.60 V at 0.4 milliseconds and 7.0 ± 2.7 mV. No LBBA lead-related complications occurred. CONCLUSIONS This first-in-human evaluation showed the feasibility of LBBAD implantation in a small cohort of patients. With current tools, implantation remains complex and time-consuming. Considering the feasibility reported and the potential benefits, further technological development in this field is warranted with evaluation of long-term safety and performance.

Abstract
BACKGROUND The benefit of an anterior mitral line (AML) in patients with persistent atrial fibrillation (AF) and anterior atrial scar undergoing ablation has never been investigated. OBJECTIVE The purpose of this study was to evaluate the outcomes of AML in addition to standard treatment compared to standard treatment alone (no AML) in this subset of patients. METHODS Patients with persistent AF and anterior low-voltage zone (LVZ) treated with AML in 3 centers were retrospectively enrolled. The patients were matched in 1:1 fashion with patients having persistent AF and anterior LVZ who underwent conventional ablation in the same centers. Matching parameters were age, LVZ burden, and repeated ablation. Primary endpoint was AF/atrial tachycardia (AT) recurrence. RESULTS One hundred eight-six patients (age 66 ± 9 years; 34% women) were selected and divided into 2 matched groups. Bidirectional conduction block was achieved in 95% of AML. After median follow-up of 2 years, AF/AT recurrence occurred in 29% of the patients in the AML group vs 48% in the no AML group (log-rank P = .024). On Cox regression multivariate analysis, left atrial volume (hazard ratio [HR] 1.03; P = .006) and AML (HR 0.46; P = .003) were significantly associated with the primary endpoint. On univariate logistic regression, lower body mass index, older age, extensive anterior LVZ, and position of the left atrial activation breakthrough away from the AML were associated with first-pass AML block. CONCLUSION In this retrospective matched analysis of patients with persistent AF and anterior scar, AML in addition to standard treatment was associated with improved AF/AT-free survival compared to standard treatment alone.

Abstract
Background Left atrial substrate may have mechanistic relevance for ablation of atrial fibrillation (AF). We sought to analyze the relationship between low-voltage zones (LVZs), transition zones, and AF recurrence in patients undergoing pulmonary vein isolation. Methods and Results We conducted a prospective multicenter study on consecutive patients undergoing pulmonary vein isolation-only approach. LVZs and transition zones (0.5-1 mV) were analyzed offline on high-density electroanatomical maps collected before pulmonary vein isolation. Overall, 262 patients (61±11 years, 31% female) with paroxysmal (130 pts) or persistent (132 pts) AF were included. After 28 months of follow-up, 73 (28%) patients experienced recurrence. An extension of more than 5% LVZ in paroxysmal AF and more than 15% in persistent AF was associated with recurrence (hazard ratio [HR], 4.4 [95% CI, 2.0-9.8], P<0.001 and HR, 1.9 [95% CI, 1.1-3.7], P=0.04, respectively). Significant association was found between LVZs and transition zones and between LVZs and left atrial volume index (LAVI) (both P<0.001). Thirty percent of patients had significantly increased LAVI without LVZs. Eight percent of patients had LVZs despite normal LAVI. Older age, female sex, oncological history, and increased AF recurrence characterized the latter subgroup. Conclusions In patients undergoing first pulmonary vein isolation, the impact of LVZs on outcomes occurs with lower burden in paroxysmal than persistent AF, suggesting that not all LVZs have equal prognostic implications. A proportional area of moderately decreased voltages accompanies LVZs, suggesting a continuous substrate instead of the dichotomous division of healthy or diseased tissue. LAVI generally correlates with LVZs, but a small subgroup of patients may present with disproportionate atrial remodeling, despite normal LAVI.

Background
In patients with heart failure with reduced ejection fraction (HFrEF) and atrial fibrillation (AF), pulmonary vein isolation (PVI) improves left ventricular ejection fraction (LVEF), along with prognosis, in a variable percentage of patients.
Aim
To investigate the predictors of LVEF recovery after PVI and to develop a prediction model for individualized assessment.
Methods
We conducted an observational, retrospective, single-center study on 111 consecutive patients with AF and HFrEF undergoing PVI. Patients were divided into Responder vs. Non-Responder according to the "Universal definition of HF". Clinical predictors were evaluated by multivariate logistic regression analysis and cross-validation technique. Independent predictors were used to build an internally validated prediction model.
Results Responders (54%) had significantly shorter QRS duration and less dilated left atria. Persistent AF and absence of a known etiology more frequent among Responders. AF recurrence was non-significantly different between the two groups (p=0.2), although clinical AF burden was lower in Responders, after PVI (p<0.001). Absence of known etiology, presence of persistent AF, left atrial volume index<50ml/m2, and QRS<120msec were independent predictors of LVEF recovery and composed the "Antwerp Score". Patients with Antwerp Score ≤1 had 90% likelihood of LVEF recovery, compared to 5% in patients with 3-6.
Conclusions Patients with wide QRS complex, known HF etiology, dilated left atria, and paroxysmal AF were less likely to recover LVEF after PVI. A new score system based on the above-mentioned parameters adequately predict LV function recovery after PVI. These results warrant confirmation and prospective validation.

Abstract
Etiologic factors and long-term outcomes of catheter ablation of atrial fibrillation (AF) in young patients have not been well characterized. This study aimed to analyze the etiologic factors and outcomes of pulmonary vein isolation (PVI) in patients with young-onset AF (young-AF, defined as having first documented episode <45 years). Consecutive patients with young-AF undergoing PVI (n = 197) in 2 academic centers were enrolled and followed for 36.1 ± 24.5 months. A control group of patients with AF onset ≥45 years (n = 554) was included. The most frequent risk factors in young-AF were intensive exercise (25%), moderate-to-heavy alcohol consumption (23%), and familial AF (22%). Compared with patients with AF onset ≥45-year, patients with young-AF were more often men (82% vs 66%, p <0.001), had more frequently paroxysmal AF (81% vs 60%, p <0.001), had less left atrial dilatation (40.9 ± 6.2 mm vs 44.2 ± 7.2 mm, p <0.001), and had lower 4-year recurrence rate after last PVI procedure (22% vs 45%, p <0.001). In young-AF, structural heart disease (SHD) was the only independent predictor of recurrence. Patients with young-AF selected to undergo cryoballoon (CB) ablation were younger (35.0 ± 7.7 vs 36.6 ± 6.7 years, p = 0.035) and had less persistent AF (6% vs 24%, p = 0.004) and coronary artery disease (2% vs 7%, p = 0.02) compared with radiofrequency ablation. After excluding patients with persistent AF and SHD, there was no difference in single procedural success between radiofrequency or CB PVI (27% vs 17%, p = 0.11). In conclusion, patients with young-AF have diverse etiologies and high single and multiprocedural PVI successes. SHD is the only independent predictor of recurrence. In patients with young-AF, there is a selection bias for CB ablation.

Abstract
INTRODUCTION Different methods are used for atrial fibrillation (AF) cycle length (CL) measurement with variable results. Previous studies of pulmonary vein (PV) CL measurement showed contradictory results on predicting PV isolation (PVI) efficacy. A novel simple method of measuring the average of 10 consecutive Fastest Atrial Repetitive Similar morphology signal (FARS10 )-CL to characterize local atrial activity rate was evaluated prospectively. METHODS The intra-observer reproducibility of FARS10 -CL and traditional AF-CL measurement of continuously fragmented coronary sinus (CS) signals were tested. We prospectively enrolled 100 consecutive patients (62±10 years, 72% male) undergoing wide antral PVI only ablation for persistent AF, measured PV-FARS10 -CLs and evaluated long-term outcome. RESULTS The Kendall area correlation between repeated traditional AF-CL measurements was -0.006 and between repeated FARS10 -CL measurements in the right and left atrial appendages, CS and PVs were 0.944, 0.859, 0.882, 0.675-0.955, respectively. Patients with recurrent atrial tachyarrhythmia had significantly longer Fastest PV-FARS10 -CL (172±41 vs. 156±41 ms, p=0.047). Patients with high burden of spontaneous low voltage zone (LVZ) had significantly longer Fastest PV-FARS10 -CL. Freedom from recurrent tachyarrhythmia at 24 months was 85% vs. 59% in patients with Fastest PV-FARS10 -CL≤140 vs. >140 ms, p=0.0018, respectively. In multivariable analysis Fastest PV-FARS10 -CL≤140 ms was the only significant predictor of freedom from recurrent tachyarrhythmia. CONCLUSIONS FARS10 -CL measurements have a high reproducibility in contrast to traditional AF-CL measurement of continuously fragmented CS signals. Patients with high burden of LVZ have longer Fastest PV-FARS10 -CLs. Fastest PV-FARS10 -CL≤140 ms is associated with a high success of wide antral PVI-only ablation approach in persistent AF.

Abstract
PURPOSE To determine the effects of the sodium content of maintenance fluid therapy on cumulative fluid balance and electrolyte disorders. METHODS We performed a randomized controlled trial of adults undergoing major thoracic surgery, randomly assigned (1:1) to receive maintenance fluids containing 154 mmol/L (Na154) or 54 mmol/L (Na54) of sodium from the start of surgery until their discharge from the ICU, the occurrence of a serious adverse event or the third postoperative day at the latest. Investigators, caregivers and patients were blinded to the treatment. Primary outcome was cumulative fluid balance. Electrolyte disturbances were assessed as secondary endpoints, different adverse events and physiological markers as safety and exploratory endpoints. FINDINGS We randomly assigned 70 patients; primary outcome data were available for 33 and 34 patients in the Na54 and Na154 treatment arms, respectively. Estimated cumulative fluid balance at 72 h was 1369 mL (95% CI 601-2137) more positive in the Na154 arm (p < 0.001), despite comparable non-study fluid sources. Hyponatremia < 135 mmol/L was encountered in four patients (11.8%) under Na54 compared to none under Na154 (p = 0.04), but there was no significantly more hyponatremia < 130 mmol/L (1 versus 0; p = 0.31). There was more hyperchloremia > 109 mmol/L under Na154 (24/35 patients, 68.6%) than under Na54 (4/34 patients, 11.8%) (p < 0.001). The treating clinicians discontinued the study due to clinical or radiographic fluid overload in six patients receiving Na154 compared to one patient under Na54 (excess risk 14.2%; 95% CI - 0.2-30.4%, p = 0.05). CONCLUSIONS In adult surgical patients, sodium-rich maintenance solutions were associated with a more positive cumulative fluid balance and hyperchloremia; hypotonic fluids were associated with mild and asymptomatic hyponatremia.

Abstract
BACKGROUND Although prescribed to every patient undergoing surgery, maintenance fluid therapy is a poorly researched part of perioperative fluid therapy. The tonicity of the chosen solutions, could be an important cause of morbidity, with hyponatremia being a potential side effect of hypotonic solutions, where isotonic solution could lead to fluid overload. METHODS The TOPMAST-trial is an ongoing prospective single-center double-blind randomized trial comparing an isotonic and a hypotonic maintenance fluid strategy during and after surgery in patients undergoing different types of major thoracic surgery. Patients receive NaCl 0.9% in glucose 5% with an added 40 mmol L-1 of potassium chloride or a premixed solution containing 54 mmol L-1 sodium, 55 mmol L-1 chloride and 26 mmol of potassium at a rate of 27 mL per kg of body weight per day. The primary hypothesis is that isotonic maintenance solutions cause a more positive perioperative fluid balance than hypotonic fluids. Different secondary safety endpoints will be explored, especially the effect of the study treatments on the occurrence electrolyte disturbances (e.g. hyponatremia, hyperchloremia) and a set of clinical endpoints. Efficacy endpoints include the need for resuscitation fluids and assessment of renal and hormonal adaptive mechanisms. An anticipated 68 patients will be included between March 2017 and January 2018. DISCUSSION The study will provide the most comprehensive evaluation of clinically important outcomes associated with the choice of perioperative maintenance fluid therapy.

Abstract
OBJECTIVES Isolated lung perfusion with gemcitabine is an effective technique for the treatment of lung metastases in an experimental model. In clinical studies, increased toxicity has been observed when combining intravenous gemcitabine with radiotherapy (RT). The goal of our study was to determine whether RT in combination with isolated lung perfusion increases lung toxicity. METHODS Rodents were randomized into eight groups: sham group, RT, intravenous gemcitabine, intravenous gemcitabine combined with RT, isolated lung perfusion with hydroxyethyl starch (HES) or gemcitabine, isolated lung perfusion with HES or gemcitabine combined with RT. Gemcitabine was administered in a dose of 40 mg/kg and RT as a single fraction of 8 Gy. The effect on lung tissue was evaluated by % fibrosis in a haematoxylin-eosin stain and by % alveoli that contained siderophages on Perls stain. A total of 36 slices were made per treatment and per stain. The results of different groups were compared using logistic regression. RESULTS There were no significant differences between treatment with intravenous gemcitabine and RT. Isolated lung perfusion with gemcitabine showed significant more histopathologic changes compared with intravenous gemcitabine (P < 0.0001). When RT was added, there was no fibrosis after intravenous gemcitabine and mild-to-moderate haemosiderosis. After isolated lung perfusion with gemcitabine combined with RT, there was moderate to severe fibrosis and mild to severe haemosiderosis. Adding RT to isolated lung perfusion with gemcitabine showed no significant difference compared to isolated lung perfusion alone. CONCLUSIONS Combination of isolated lung perfusion and RT is feasible in an experimental model. No additional toxicity of RT was observed compared to isolated lung perfusion alone. Further studies are necessary to determine efficacy of this combined treatment.
