  Abstract
  
  PURPOSE:
  Pulmonary vein isolation (PVI) using cryoablation (PVI-C) is a widespread therapy for treating symptomatic, recurrent atrial fibrillation (AF). The impacts of sex on efficacy and safety of PVI-C in a real-world clinical practice is lacking. In a multicenter prospective project, we evaluated whether clinical characteristics, procedure parameters, procedural complications, long-term AF recurrence rates, and/or AF-related symptoms differed according to sex in patients treated with PVI-C.
  
  METHODS:
  Data from the study population were collected in the framework of the 1STOP ClinicalService® project, involving 47 Italian cardiology centers. Multivariable statistical analyses were conducted to determine if any baseline clinical characteristics impacted the efficacy of PVI-C.
  
  RESULTS:
  From April 2012, 2125 patients (27% female, 59?±?11 years, 73% paroxysmal AF, and mean left atrial diameter?=?42?±?8 mm) underwent PVI-C. According to baseline characteristics, women were more likely to be older, with higher clinical risk scores (e.g., CHADS-VASc), and a higher number of tested antiarrhythmic drugs before the index PVI-C procedure. Male and female cohorts showed comparable procedure time (mean?=?107.7?±?46.8 min) and a similar incidence of periprocedural complications (4.5% overall), even after adjustment for baseline characteristics (P?=?0.880). The multivariable analyses demonstrated that the strongest predictor of AF recurrences was sex (0.74; 95% CI 0.58-0.93; P?=?0.011). After propensity score adjustment, the hazard ratio from a multivariable model, which included age and AF type (persistent) as covariates, was 0.76 (0.60-0.97) (P?=?0.025).
  
  CONCLUSIONS:
  According to the 1STOP project, in a real-world setting, PVI-C was relatively safe regardless of the patient's sex; however, when considering efficacy of the procedure, female patients had a lower long-term efficacy in comparison to males.

• Unusual presence of 'ghosts' following lead extraction for recurrent reactive pericarditis: a case report.

  Abstract
  
  Background:
  The presence of a persistent fibrous sheath in right-sided heart chambers after transvenous lead extraction has already been described in some studies as echocardiographic tubular mobile masses called 'ghosts'. Their presence has been associated with cardiac device-related infective endocarditis or local device infection, but to the best of our knowledge, this is the first case where 'ghosts' have been reported among non-infected patients.
  
  Case summary:
  We present a case of a 73-year-old woman hospitalized due to worsening dyspnoea and a significant pericardial effusion, relapsed after pericardiocentesis with removal of about 1500?mL of non-haemorrhagic fluid. The patient's history revealed a previous dual-chamber pacemaker implantation due to symptomatic sick sinus syndrome. Transoesophageal echocardiography (TOE), essential to exclude endocarditis vegetations suggested an etiopathogenesis of mechanical irritation caused by the distal end of the passive fixation atrial lead on the right atrial appendage wall. Considering the echocardiographic report and the condition of reactive pericarditis with the early relapse of the significant pericardial effusion after pericardiocentesis, we opted for a lead removal procedure to eliminate the stimulus causing the irritation, with transoesophageal echocardiographic monitoring, thus the early detection of a 'ghost' was possible.
  
  Discussion:
  This is the first clinical case describing the presence of fibrin 'ghosts' sometime after the implantation of a pacemaker, highlighting a non-exclusively infectious genesis, and emphasizing the importance of TOE for the early detection of this post-extraction complication and its monitoring.

  Abstract
  
  Cardiac Resynchronization Therapy (CRT) is known as a highly effective therapy in advanced heart failure patients with cardiac dyssynchrony. However, still one third of patients do not respond (or sub-optimally respond) to CRT. Among the many contributors for the high rate of non-responders, the lack of procedures dedicated to CRT device settings optimization (parameters to regulate AV synchrony and VV synchrony) is known as one of the most frequent. The most recent HF/CRT Guidelines do not recommend to carry-out optimization procedures in every CRT patient; they simply state those procedures "could be useful in selected patients", even though their role in improving response has not been proven. Echocardiography techniques still remain the gold-standard reference method to the purpose of CRT settings optimization. However, due to its severe limitations in the routine of CRT patients management (time and resource consuming, scarce reproducibility, inter and intra-operator dependency), echocardiography optimization is widely under-utilized in the real-world of CRT follow-up visits. As a consequence, device-based techniques have been developed to by-pass the need for repeated echo examinations to optimize CRT settings. In this report the available device-based optimization techniques onboard on CRT devices are shortly reviewed, with a specific focus on clinical outcomes observed in trials comparing these methods vs. clinical practice or echo-guided optimization methods. Particular emphasis is dedicated to hemodynamic methods and automaticity of optimization algorithms (making real the concept of "ambulatory CRT optimization"). In fact a hemodynamic-based approach combined with a concept of frequent re-optimization has been associated - although retrospectively - with a better clinical outcome on the long-term follow-up of CRT patients. Large randomized trials are ongoing to prospectively clarify the impact of automatic optimization procedures.

  Abstract
  
  BACKGROUND:
  Reverse remodeling and increased LVEF after CRT correlate with survival and heart failure hospitalizations, but their relationship with the risk of SCD is unclear. We aimed to evaluate whether exceeding a threshold value of 35% for left ventricular ejection fraction (LVEF) 1 year after cardiac resynchronization therapy (CRT) predicts survival and freedom from sudden cardiac death (SCD).
  
  METHODS:
  330 patients who survived ? 6 months after CRT (males 80%, age 62 ± 11 years) were grouped according to 1-year LVEF ? 35% (Group 1, n=187, 57%) or >35% (Group 2, n=143, 43%). According to changes vs. baseline (reduction of left end-systolic volume [LVESV] ? 10% or increase of LVEF% > 10 units), patients were also classified as echocardiographic (Echo) non-responders (Group A, n=152, 46%) or responders (Group B, n=178, 54%).
  
  RESULTS:
  At baseline, LVESV volume was larger and LVEF was lower in Group 1 vs. Group 2 (p<0.001). After 1 year, echocardiographic improvement was greater in Group 2 vs. Group 1 (p<0.001 for changes in both LVESV and LVEF). Over a median follow-up of 49 months, 47 patients (14%) died, 36 in Group 1 vs. 11 in Group 2 (19% vs. 8%, p=0.004). A significantly higher rate of freedom from all-cause mortality (p=0.002), cardiovascular mortality (p<0.001) and SCD (p<0.001) was observed in Group 2. Multivariate analysis demonstrated that only 1-year LVEF >35% was associated with freedom from SCD/VF.
  
  CONCLUSIONS:
  LVEF >35% after 1 year of CRT characterizes a favorable long-term outcome, with a very low risk for SCD.

  Abstract
  
  AIMS:
  To assess the diagnostic yield of new external loop recorders (ELRs) in patients with history of syncope, pre-syncope, and sustained palpitations.
  
  METHODS AND RESULTS:
  Since 2005, we have established a registry including patients who consecutively received ELR monitoring for unexplained syncope or pre-syncope/palpitations. The registry included 307 patients (61% females, age 58 ± 19 years, range 8-94 years) monitored by high-capacity memory ELR of two subsequent generations: SpiderFlash-A(®) (SFA(®), Sorin CRM), storing two-lead electrocardiogram (ECG) patient-activated recordings by loop-recording technique (191 patients, 54 patients with syncope, years 2005-09), and SpiderFlash-T(®) (SFT(®)), adding auto-trigger detection for pauses, bradycardia, and supraventricular/ventricular arrhythmias (116 patients, 38 patients with syncope, years 2009-12). All the patients previously underwent routine workup for syncope or palpitation, including one or more 24 h Holter, not conclusive for diagnosis. Mean monitoring duration was 24.1 ± 8.9 days. Among 215 patients with palpitations, a conclusive diagnosis was obtained in 184 patients (86% diagnostic yield for palpitation). Among 92 patients with syncope, a conclusive diagnosis was obtained in 16 patients (17% clinical diagnostic yield for syncope), with recording during syncope of significant arrhythmias in 9 patients, and sinus rhythm in 7 patients. Furthermore, asymptomatic arrhythmias were de novo detected in 12 patients (13%), mainly by auto-trigger detection, suggesting an arrhythmic origin of the syncope.
  
  CONCLUSIONS:
  The diagnostic yield of ELR in patients with syncope, pre-syncope, or palpitation of unknown origin after routine workup was similar to implantable loop recorder (ILR) within the same timeframe, therefore, ELR could be considered for patients candidate for long-term ECG monitoring, stepwise before ILR.

• [Risk stratification for sudden cardiac death: should we juist consider ejection fraction?].
  G Ital Cardiol (Rome)

  Abstract
  
  Sudden cardiac arrest is a leading cause of death in industrialized countries. There is solid clinical evidence for implantable cardioverter-defibrillators as the only effective means of preventing sudden cardiac arrest and reducing mortality in high-risk patients. The therapeutic strategy has definitively been validated, but we have not yet identified with the same effectiveness the patients who most likely will benefit from such therapy. Risk stratification of sudden death is therefore one of the major unresolved issues of modern cardiology. Current guidelines identify ejection fraction as the only instrumental parameter for risk stratification of sudden cardiac death. It is strongly consolidated from "old and new" clinical trials that ejection fraction reduction is the real powerful predictor of total mortality and sudden death regardless of its etiology; however it cannot be considered as an indisputable gold standard predictor of risk because it lacks of sensitivity and specificity in the prediction of sudden death. It is reasonable that many factors besides ejection fraction influence patient prognosis; there are different aspects suggesting that a reduction in ejection fraction is a risk factor only in combination with other risk factors. The implantable cardioverter-defibrillator therapy is expensive and associated with possible complications. We therefore need better methods for risk stratification of our patients in order to increase the real cost-effectiveness of current and future treatment options.

• Surgical ablation of arrhythmias.
  Ital Heart J

  2005 Mar;6(3):231-40.

  Abstract
  
  The surgical approach was the earliest therapeutic ablation of hyperkinetic arrhythmias. Following the progressive improvements in electrophysiological mapping and operative techniques, new surgical approaches have been developed for the treatment of those arrhythmias related to ectopic phenomena or reentry mechanisms. These procedures have been proven to be highly effective but the associated morbidity and mortality were unacceptably high. More recent and advanced techniques of transcatheter ablation have revolutionized the treatment of these arrhythmias and now represent the treatment of choice in the majority of cases. However, the significant reduction in the operative risk and the improvement in patient outcome with respect to the past, thanks to a better patient selection and to advances in the surgical and myocardial protection techniques, make do that the surgical approach to some forms of arrhythmias is still valid, especially in those cases requiring associated surgery: atrial tachyarrhythmias in patients with congenital heart disease, post-ischemic ventricular tachycardias in patients who necessitate myocardial revascularization, and/or ventricular remodeling and chronic or paroxysmal atrial fibrillation in patients who require cardiac surgery. New techniques such as radiofrequency, microwaves and cryoablation guarantee the creation of linear and transmural lesions with minimum damage to the cardiac structures and appear very interesting as they are surgically simple and associated with shorter procedure times and less complications. The possibility of performing the ablative procedure completely on the epicardial surface may open the way for atrial fibrillation surgery on a totally beating heart and for procedures that are ever less invasive thus enabling treatment of patients without associated surgical indications.

  Abstract
  
  INTRODUCTION:
  Biventricular pacing improves functional status in the majority of patients with drug-refractory heart failure, dilated cardiomyopathy, and interventricular conduction delay. The aim of this study was to analyze the baseline clinical and functional data of a cohort of patients implanted with a biventricular stimulation system in a single-center experience, to verify if the pathophysiologic characteristics of patients affect outcome, and to determine if preliminary identification of the right candidates for the new therapy is possible with noninvasive parameters.
  
  METHODS AND RESULTS:
  Since March 1999, 52 patients with advanced heart failure (idiopathic cardiomyopathy 50%, ischemic cardiomyopathy 35%, other etiology 15%) and left bundle branch block underwent cardiac resynchronization and were followed prospectively. Paired analysis over mean (+/- SD) follow-up of 348 +/- 154 days showed an overall significant decrease of QRS width (baseline 194 +/- 33.2 msec vs follow-up 159.6 +/- 20.1 msec), New York Heart Association (NYHA) functional class (baseline 3.2 +/- 0.5 vs follow-up 2.3 +/- 0.5), quality-of-life score (baseline 54 +/- 25 vs follow-up 25 +/- 16), and increase of maximal VO2 (baseline 12.6 +/- 2.5 mL/kg/min vs follow-up 15.0 +/- 3.3 mL/kg/min). There were 80% responders (documented, persistent decrease > or = 1 NYHA class) and 20% nonresponders (same NYHA class or decline of status; need for heart transplant; death due to progressive pump failure). No significant differences in baseline clinical and functional variables between the two subgroups were observed. In responders, there was a highly significant global improvement of all variables; in nonresponders, no parameters changed between baseline and follow-up.
  
  CONCLUSION:
  These data confirm the role of biventricular pacing in improving the functional status of the great majority of a selected patient population having advanced heart failure and left bundle branch block with wide QRS complex. Basal demographic, clinical, and functional characteristics are not helpful in preliminary selection of responders. Simple evaluation of NYHA class confirms favorable outcome (improvement of functional and hemodynamic status).
