Abstract
Abstract
Background
The structural alterations of arrhythmogenic right ventricular (RV) cardiomyopathy (ARVC) mainly involve the RV outflow tract (RVOT), but RVOT systolic function has been poorly investigated.
Purpose
We aimed to evaluate the Doppler Velocity Ratio (DVR) as a novel echocardiographic parameter for ARVC diagnosis.
Methods
30 consecutive ARVC adult patients, 45 asymptomatic healthy volunteers and 45 consecutive patients with RV dysfunction due to ARVC mimics were prospectively enrolled between May 2019 and December 2021 and received complete transthoracic echocardiography examinations. The DVR was calculated as the ratio of RV free wall systolic velocity to RVOT systolic velocity at Doppler tissue imaging. The main study outcomes were to compare the DVR among ARVC patients, healthy controls, and mimics and to assess its diagnostic value in ARVC.
Results
120 patients were included. Mean age was 55±17 years; 46 (38.3%) patients were female. The DVR was significantly higher in ARVC subjects (1.59±0.41) compared to both healthy controls (1.16±0.14, P<0.001) and mimics (1.17±0.23, P<0.001), but similar between healthy controls and mimics (P=1.000). The DVR cut-off value with the highest accuracy for ARVC diagnosis was 1.33 (sensitivity=80.0%, specificity=86.7%). The area under the curve of DVR alone was significantly superior to that of the major echocardiographic 2010 Task Force Criteria (0.833 vs 0.672 respectively, P=0.034). The net reclassification improvement for DVR alone against the major echocardiographic 2010 Task Force Criteria was 32.2% (P=0.023).
Conclusions
The DVR is a simple novel echocardiographic parameter with high accuracy for ARVC diagnosis.

Abstract
Abstract
Background
Bileaflet mitral valve prolapse (bMVP) has been linked to major arrhythmic events and sudden cardiac death (SCD). Solid evidence of consistent predictors of SCD in this setting is still lacking. Echocardiography is the best tool for the analysis of ventricle mechanics and for the correlation with electrical myocardial activation. The aim of this study was to find new predictors of malignant events within an arrhythmic MVP population.
Methods
We conducted a retrospective comparative analysis, selecting 22 patients with bMVP with a high arrhythmic risk profile. 6 of them had a previous major arrhythmic event (5 aborted SCD, one cardiogenic syncope) and previously received ICD implantation (ICD–MVP), while 16 presented with a high arrhythmic burden without major events (A–MVP). All patients underwent transthoracic echocardiography in the last year. Each echocardiogram followed a specific protocol focused on mitral valve anatomy and ventricular contraction using 2D imaging, 3D imaging, tissue doppler imaging and speckle tracking analysis.
Results
ICD–MVP group, compared with A–MVP group, presented a longer anterior leaflet (AML) length (28,6 mm, IQR: 24,1–31,1 mm; vs 21,4 mm, IQR: 20,4–24,0 mm; p = 0,03), larger mitral valve annulus (MVA) indexed area (6,88 cm2/m2, IQR 6,27–7,87 cm2/m2 vs 5,44 cm2/m2, IQR: 4,93–6,15 cm2/m2, p = 0,02), lower MVA anteroposterior diameter/AML length ratio (1,24, IQR: 1,21–1,41 vs 1,50, IQR 1,32–1,62; p = 0,049), higher inferolateral basal S3 velocity (26 cm/s, IQR: 20,8–29,6 cm/s vs 14,2 cm/s, IQR 10,1–21,3 cm/s; p = 0,02) and a greater mechanical dispersion (MD) of the basal and mid–ventricular segments calculated with speckle tracking (128 ms, IQR: 125–131 ms; vs 58 ms, IQR 45–106 ms; p = 0,03). Mitral regurgitation grading, instead, did not correlate with malignant events. Best predictors of malignant events were AML length and MD of basal and mid–ventricular segments. Cut–off values with highest sensibility and specificity above 80% were 26 mm for AML length and 122 ms for MD of basal and mid–ventricular segments. Logistic bivariate regression confirmed AML length as an independent predictor of malignant events (p = 0,01), while MD of basal and mid–ventricular segments showed a trend toward significancy (p = 0,07).
Conclusion
Five parameters were found to be predictors of malignant events in a high–risk MVP population. AML length and MD of the basal and mid–ventricular segments presented the best predictive value.

Abstract
Abstract
Background
Incessant pericarditis is defined as pericarditis with persistent symptoms without a symptom-free interval of 4 to 6 weeks despite therapy. On the contrary, recurrent pericarditis is characterized by recurring symptoms after a symptom-free interval of at least 4 to 6 weeks, allowing the completion of therapy.
Aims
The aim of this study is to assess the risk of complicated pericarditis and related hospitalizations according to the clinical pattern of incessant or recurrent pericarditis.
Methods
From January 2017 to December 2018, all consecutive patients admitted to AOU Città della Salute (Turin, IT) for pericarditis were included in a prospective cohort study with a clinical and echocardiographic follow-up at 1, 3, and 6 months, and then every 6 months.
Results
We included 147 patients (median age, 50.9 years [IQR, 28.5]; 49.7% women, 89% had idiopathic aetiology, 11% had pericarditis related to systemic inflammatory disease/postcardiac injury syndrome, 80% had pericardial effusion, and 62% had elevated C-reactive protein >5 mg/L). Patients were treated according to ESC guidelines. After a median follow-up of 14 months (IQR, 9 months), adverse events were recorded in 54/147 patients (36.7%): nonidiopathic/viral aetiology in 16 of 147 cases (10.9%), recurrent pericarditis/persistent symptoms in 53 of 147 cases (36.1%), cardiac tamponade in 4/147 cases (2.7%), persistent CP in 4/147 cases (2.7%), and hospitalization related to pericarditis in 38/147 cases (25.9%). An incessant course was reported in 18 of 147 cases (12%). The risk of complications was higher in patients with incessant pericarditis (Figure) – especially CP – compared to nonincessant course (22.2% versus 0%, respectively; P<0.001). Patients with incessant pericarditis more commonly had echocardiographic evidence of CP (77.8% vs. 9.3%; P<0.001) and thickened pericardium on multimodality imaging (66.7% vs. 4.7%; P<0.001). These findings were reversible with medical therapy with the use of anakinra (100 mg/d) and colchicine in all but 4 cases that progressed to persistent CP, which were referred for pericardiectomy. An analysis of risk factors for complicated pericarditis and hospitalization using Cox proportional hazards regression analysis identified the following risk factors: large pericardial effusion (hazard ratio, 7.63 [95% CI, 3.09–18.83]), elevated C-reactive protein >5 mg/L (hazard ratio, 5.55 [95% CI, 1.87–16.44]), and incessant course (HR, 17.10 [95% CI, 7.63–38.33]).
Conclusions
This study highlights that an incessant course of pericarditis is a possible new risk factor for complications and especially for developing constriction. In clinical practice, the detection of an incessant course, as well as imaging findings of constriction and pericardial thickening, should prompt more diagnostic testing, a close follow-up, and more aggressive therapy to prevent complications and persistent constriction.

Abstract
Abstract
Background
A strategy of percutaneous coronary intervention (PCI) driven by FFR (Fractional Flow Reserve) has demonstrated to reduce adverse events through the “deferring” of unnecessary stenting procedures compared to PCI guided by angiographic evaluation of stenosis. Coronary Artery Bypass Graft (CABG) represents another option for revascularization, being superior to PCI in patients with diffuse disease. In this setting, some evidence has been provided about physiological driven CABG procedures, but studies reported contrasting results regarding clinical benefits and outcomes at follow up.
The aim of this meta-analysis is to evaluate clinical and procedural impact of FFR versus angiographic guided surgical revascularization and assess outcomes at follow up.
Methods
All randomized controlled trials (RCTs) or observational studies with multivariable adjustment or propensity matching were included. MACE (Major Adverse Cardiac Events) was the primary end point, while its single components (death, myocardial infarction and revascularization) along with number of grafts and percent of off-pump CABG were the secondary ones. Of 86 studies identified, 4 articles were included in this review, representing a combined total of 777 patients (426 angio-guided and 351 FFR-guided). Mean age was 66±2.1, 80% man, 74% hypertension, 71% hyperlipidemia, 33% diabetes, 39% smokers. Mean EuroSCORE I was 2.7. 18% a prior MI, and 25% a prior PCI. Coronary lesions were allocated as follow: 36% left anterior descending artery, 32% circumflex artery, 27% right coronary artery. Mean follow up was 30 months. At the follow up, rates of MACE did not differ (MACE OR 1.31:0.88–1.96), as those of death (OR 1.47:0.86–2.51), of MI (OR 1.80:0.89–3.63), and of target vessel revascularization (1.03: 0.54–1.97.). FFR-guided CABG was associated with more off-pump surgical procedure (OR 0.58, IC 0.34–0.97) and shorter hospitalization time (8.2±2.49 vs 8,87±3,25 p<0.01). FFR- guided CABG was associated more frequently with off-pump surgical procedure (OR 0.58:0.34–0.97) with fewer anastomes (2.5 vs 3), leading to higher rates of global arteria revascularization in FFR group (56% vs. 45%) and higher rates of venous grafts in angio-guided group (55% vs. 44%). Shorter hospitalization time was recorded in FFR patients (8.2±2.49 vs 8,87±3,25 days, p<0.01). Graft patency at follow up was not statistically higher in the FFR guided group (OR 0.67, CI 95% 0.32–1,39, all CI 95%).
Conclusions
FFR-guided surgical revascularization is associated with more off-pump procedures, a lower number of surgical anastomoses and more arterial grafts compared to angiography guided CABG. These differences lead to a shorter hospitalization time in the FFR-guided group compared to the angiography-guided group. No difference between two groups in MACE, overall death and MI was observed during the follow up. RCT with longer follow up are needed to evaluate long term outcomes.

Abstract
Abstract
Background
Heart transplantation (HTx) is considered the best available treatment for patients with end stage heart failure. Candidate evaluation with right heart catheterization (RHC) is fundamental in order to exclude pulmonary hypertension with irreversible high pulmonary vascular resistance (PVR), which is associated with elevated post-HTx mortality. PVR, rather than directly measured, is derived by cardiac output and pulmonary artery pressures, which are strictly dependent on right ventricular (RV) function. The pulmonary artery pulsatility index (PAPi) is a hemodynamic parameter integrating the information of RV function and of pulmonary circulation, which could be useful in pre-HTx evaluation.
Purpose
We designed this study to evaluate the potential predictive influence of pre-HTx PAPi on post-HTx survival and to assess whether this index could add useful information in the pre-HTx evaluation of patients with advanced heart failure.
Methods
Consecutive adult HTx recipient at two medium-large tranplant centers between 2000 and 2017 with available data on pre-HTx RHC were retrospectively included. PAPi was calculated as the ratio of pulmonary artery pulse pressure to right atrial pressure. PAPi values in the lowest quartile were defined as reduced (PAPi<1.67). The primary endpoint was all-cause mortality at 1-year post-HTx. The association of reduced PAPi with the primary endpoint was evaluated. Cox regression was used to adjust for clinical and hemodynamic variables. Analyses stratified by PVR status (≥3 WU vs. <3 WU) were also performed.
Results
Among 655 HTx recipients (female 20,8%, age 53±11 years), median pre-HTx PAPi was 3.0 (interquartile range 1.67–5.32). Patients in the lowest versus the remaining PAPi quartiles had significantly reduced 1-year survival (78.0% vs 87.2%, p=0.006), also after adjusting for age, estimated glomerular filtration rate, total bilirubin, high PVR and urgent transplantation (adj-hazard ratio: 0.64; 95% confidence interval 0.51–0.82). When stratifying patients by estimated PVR status, reduced PAPi was associated with worse 1-year survival among patients with normal PVR (78.3% vs. 88.3% p=0.011), but not in those with increased PVR (78.0% vs. 82.6%, p=0.36) (Figure 1).
Conclusions
Pre-HTx PAPi, integrating information of RV function and pulmonary circulation, provides incremental prognostic value over traditional clinical and hemodynamic parameters among HTx recipient. The prognostic value appears important among patients with normal estimated PVR, possibly due to an underestimation of PVR in patients with impaired RV function. The integration of PAPi in the pre-HTx evaluation may lead to better patient selection and post-HTx survival.

Abstract
Abstract
Background
About 40% of patients undergoing transcatheter aortic valve replacement (TAVR) have a history of atrial fibrillation (AF) and an additional 10% develop AF after TAVR. However, there is paucity of data regarding the optimal antithrombotic regimen following TAVR in patients with a clinical indication for oral anticoagulants (OAC).
Purpose
To compare the prognostic impact of OAC plus at least one antiplatelet agent (APT) versus OAC therapy alone in patients undergoing TAVR.
Methods
We systematically searched the literature for studies evaluating the comparative efficacy and safety of OAC + APT versus OAC alone in TAVR. Random-effect meta-analysis was performed comparing clinical outcomes between the two groups. All-cause mortality and cardiovascular mortality were the efficacy outcomes. Stroke and major bleeding, defined as Bleeding Academic Research Consortium bleeding types 3 to 5, constituted the safety outcome.
Results
Overall, 398 titles and abstracts were identified through database searching. Four observational studies were selected, for a total of 1929 patients. After a median follow-up of 18.5 months (IQR 11.3–29.3), OAC + APT increased major bleeding events compared to OAC alone (OR=1.79; 95% CI 1.21–2.66; P=0.004) with no difference in stroke (OR 01.02; 95% CI 0.52–2.01; P=0.95), all-cause mortality (OR=1.07; 95% CI 0.78–1.47; P=0.66) and cardiovascular mortality (OR=1.08; 95% CI 0.79–1.47; P=0.62).
Conclusion
A combination strategy of OAC + APT provides increased risk of bleeding compared to OAC therapy alone in patients undergoing TAVR with similar outcomes in terms of stroke, all-cause mortality and cardiovascular mortality; therefore, when feasible, it should be advised not to add APT on top of OAC therapy in patients without other clinical indications for APT treatment.

Abstract
Abstract
Background
Brugada syndrome (BrS) is an inherited channelopathy with an increased risk of supraventricular, ventricular arrhythmias (VAs) and sudden cardiac death (SCD). Implantable cardioverter-defibrillator (ICD) is a cornerstone of SCD prevention, but it does not reduce the incidence of life-threatening VAs and it can carry substantial complications. Hydroquinidine (HQ) is a class IA antiarrhythmic drug used for electrical storms, to reduce ICD's appropriate discharges and as an alternative to ICD in children with BrS or in patients with a contraindication to ICD. Nevertheless, HQ's side effects may undermine treatment compliance.
Purpose
The aim of this study was to evaluate the efficacy and safety of HQ in reducing VAs (ventricular fibrillation, sustained and non-sustained ventricular tachycardia) inducibility at electrophysiology study (EPS) and atrial fibrillation/flutter (AF/AFL) or VAs recurrence in patients with BrS.
Methods
From the prospective Piedmont Brugada Registry, patients treated with HQ were selected and divided into three groups according to the indication for HQ initiation: index EPS positive for VAs induction (group 1), secondary prevention of AF/AFl (group 2), secondary prevention of VAs (group 3). In group 3 recurrence of VAs was monitored by implantable devices or by periodic 24-hour ECG Holter monitoring. In 5 patients HQ was started for reasons different from the above mentioned, so they were considered only for safety outcomes. Safety was assessed considering the occurrence of HQ side effects and their impact on treatment discontinuation.
Results
A total of 98 patients (79 males, 80,6%) were included. Median follow-up was 61 months (IQR 31–89 months). None of the baseline clinical characteristics was associated with arrhythmic recurrences. Among 46 patients in group 1 HQ was effective in reducing EPS inducibility in 91.9% of patients (p<0.0001); in group 2 (31 patients) HQ reduced palpitations [before HQ 83,8%, with HQ 27,6%, RRR 67.1%, NNT 1.8; p<0.0001] and no AF/AFL recurrence was recorded during follow-up (p<0.0001); in group 3 (17 patients; 70.6% with ICD/LR implanted) VAs recurrences were significantly reduced in patients with HQ (5.9% recurrence rate, p<0.0001). Overall, no cardiac arrest occurred during follow-up. At ECG, HQ determined a significant increase in QTc duration (V5-lead mean QTc duration pre-HQ 406 ms vs with HQ 428 ms; p=0.001).
Overall, 28.6% of patients presented HQ-related side effects, mainly due to gastrointestinal intolerance (18.3%). Treatment discontinuation rate was 25% but only about half of these patients discontinued HQ for adverse events (29.2% for GI intolerance, 16.7% for drug-induced QTc prolongation, 8.3% for elevated liver enzymes; 45.8% self-discontinuation).
Conclusions
In patients with BrS, HQ was effective in reducing VAs inducibility at EPS, AF/AFL and VAs recurrences; moreover, it was effective in reducing symptoms. Overall, HQ proved to be safe and well-tolerated.

Abstract
Abstract
Background and aim
Myotonic Dystrophy (MD) is the most common inherited muscular dystrophy of the adult. Cardiac manifestation, including arrhythmias and conduction disorders, contributes significantly to the morbidity and mortality of the disease. The transition from a subclinical form of cardiac involvement to potentially life-threating manifestations is highly variable and not yet entirely understood. Aim of this work is to evaluate whether PQ interval (PQi) prolongation could be a reliable marker to predict left and right ventricle impairment and the necessity of a stricter monitoring.
Methods
In this retrospective cohort study, we selected all consecutive patients with a confirmed diagnosis of MD (type 1 and type 2) referred to our Centre. We performed clinical, laboratoristic and instrumental assessments (every 3, 6 or 12 months), tailored on each patient's features. Every patient was treated according to the latest guidelines for pharmacological and device therapy. ECG (recorded at 25 and 50 mm/sec), 24h ECG Holter and transthoracic echocardiography were performed at least yearly. Cardiac Magnetic Resonance was requested to better stratify intermediate risk patients to implantable device therapy.
Results
A total of 72 patients (age 48±15 years, 39% female) were included in the analysis. Patients with MD type 1 and type 2 were referred to our Centre after a mean period of 12 years (SD ±8 years) from initial diagnosis. After a mean follow-up of 5 years (±4 years), 8 patients died (mean age at death: 60±12.4 years), all of them for respiratory insufficiency. We evaluated PQ interval (PQi) evolution and type I AVB onset. No statistically significant differences emerged when stratifying for type I AVB. Nevertheless, a PQi increase of more than 20 ms during the follow-up (even if PQ <200 ms) is significantly associated with lower values of TAPSE and greater LVEDD, while no differences emerged for LVEF, dyastolic function and other echocardiographic parameters. Moreover, the evolution of PQ interval is associated with an increasing number of supraventricular arrhythmias and a worse prognosis (shorter interval from first cardiac symptom to death, p 0.025), despite optimal medical therapy.
Conclusions
Although relatively rare, MD is a challenge for present Cardiologists. How and when to treat those patients is not codified in guidelines or consensus papers. This study suggests PQi variation as a proxy for critical evolution of MD cardiac involvement. ECG and its modification during lifetime seem pivotal for these patients' care, qualifying as a red flag for stringent follow-up. Further evidences, on larger cohorts, are needed to validate these findings.

Abstract
Abstract
Background
Surgical aortic valve replacement has been the treatment of choice for patients with aortic valve disease before the arrival of transcatheter aortic valve replacement (TAVI), although limited by degeneration of the bioprosthesis. “Redo” intervention itself is burdened by high risk of complications and valve-in-valve (ViV) TAVI could be a valid strategy of redo for patients with comorbidities. The aim of this meta-analysis is to give an overview of the state of the art of ViV TAVI in high-risk patients, analyzing efficacy, safety, intra-hospital outcomes and 1-year outcomes and assess predictors of survival at short and mid-term follow up.
Methods
Two independent reviewers screened all studies investigating patients undergoing ViV TAVI. PubMed database was searched for reports published in English according to the following highly sensitive strategy: (Transcatheter[All Fields] AND “aortic”[All Fields]) AND valve-in-valve[All Fields] AND “implantation”[All Fields] NOT (review[pt] OR editorial[pt] OR letter[pt])AND “humans”[MeSH Terms]). Mortality at 30 days and at 1 year were the primary end point, while procedural and short-term outcomes and echocardiographic parameters at hospital discharge were the secondary end points.
Results
Of 286 studies identified, 26 articles were included, with a total of 1448 patients. Median age was 78.8 years, 57.7% of the patients were male. Median STS-predicted risk of mortality was 9.4% while median Logistic EuroSCORE was 31.3%. Median age of bioprosthesis was 10 years with 84.6% of stented valves. Stenosis (45%), followed by regurgitation (31%) and mixed defects (21%) were the causes of prosthesis failure. Diameter of the degenerated valve was ≤21 mm in 25.4%, 22–25 mm in 55% and >25mm in 11.7% of the patients. Transfemoral approach was preferred (76%), with a prevalence of balloon expandable valve (73.3%). Mean post procedural gradient was 16.7±0.8 mmHg. Mean follow up was 376 days. Overall and cardiovascular mortality at 30 days was 6.5% and 5.5% respectively, while at 1 year it was 14.5% and 8.9% respectively. Regarding short-term outcomes, overall bleeding (10.4%), pacemaker implantation (9.4%) and vascular complications (8.3%) were the most common peri-procedural complications, while stroke (2.3%), myocardial infarction (2.7%) and coronary obstruction (2.8%) were less frequent. At meta-regression analysis study year (p<0.001), Logistic Euroscore (p<0.01) and valve diameter ≤21 mm (p<0.05) at 30 days, and stenosis as reason for failure (p=0.05) at 1 year were identified as possible predictors of survival.
Conclusions
Percutaneous valve-in-valve aortic valve implantation offers a valid strategy to treat high risk patients with a degenerative bioprosthesis. Short and mid-term outcomes are substantially superimposable to those of TAVI, except for coronary obstruction which appears more frequent. Future studies are needed to find predictors of long- term survival and outcomes in lower risk patients.

None of the author have conflict of interest to disclose.
Background
As transcatheter aortic-valve implantation (TAVI) procedures have increased, the need of a permanent pacemaker (PPM) is a complication to be taken into account.
Objective
The aim of this study is to identify clinical, electrocardiographic (ECG) and procedural predictors for PPM requirement after TAVI.
Methods
The present is a single centre, retrospective study. All consecutive patients with severe symptomatic aortic stenosis who underwent TAVI had continuous ECG monitoring. Pre and post TAVI 12-leads ECG were analysed. We arbitrarily divided the patients into early and late PPM implantation (beyond the 3rd day after TAVI). The primary endpoint of the study was to identify electrocardiographic predictors of PPM implantation after TAVI, and the secondary endpoint was to identify other clinical or procedure-related predictive factors.
Results
Of 431 patients who underwent TAVI, 77 (18%) required a PPM, and 30 (7%) had late PPM implantations. Pre-operative RBBB implies more than five-fold increase of the risk of PPM implantation after TAVI (OR 5,43, CI 2.11 - 13.99, P = 0.000), whereas the history of syncope is associated with a two-fold increase of the risk (OR 2.00, CI 1.01 - 3.96, P = 0.044), and maintains its predictive value also in the late PPM subgroup (OR 2.76, CI 1.11 – 6.82, P = 0.028).
Conclusions
It is hard to predict the need of a PPM in the individual patients, but careful evaluation of pre-operative 12-lead ECG looking for pre-existing RBBB and an history of syncope, can individuate the group of patients with an increased risk of PPM requirement.

Abstract
Abstract
Introduction
In new generation drug eluting stents (DESs) era, the impact of stent geometry on freedom from recurrent events has been poorly explored. Impact of struts thickness, number of crowns and connectors on clinical outcomes was evaluated in the present study.
Methods
Randomized controlled trials comparing last generation DESs were selected. The primary endpoint was the rate of target lesion revascularization (TLR), while secondary was Definite Stent Thrombosis (ST).
Results
53 studies with 52006 patients were included. A struts thickness ≤81 nm was associated with a lower incidence of TLR (2.9%: 2.4–3.4 vs. 3.6%: 3.0–4.3) and ST (0.8%: 0.6–1.1 vs. 1.3%: 0.9–1.8). A mean number of connectors >2.5 was also associated with a lower incidence of TLR (3.2%: 2.8–3.6 vs. 3.5%: 2.9–4.2) and ST (1.0%:0.8–1.3 vs. 1.3%: 0.9–1.7 vs for ST). On the other hand, stents with average number of crowns <7.5 did not perform better than stents with higher average number of crowns.
Conclusions
The findings of the study support that lower struts thickness and higher numbers of connectors have a positive clinical outcome reducing stent thrombosis and target lesion revascularizations, while the average number of stent crowns plays a secondary role.

Abstract
Abstract
Background
The incidence of patients with refractory angina (RA) is increasing. Medical therapy for RA is limited and prognosis is poor. Experimental data and small clinical studies suggest that the use of Extracorporeal shockwave myocardial revascularization (ESMR) may contribute to angiogenesis and improve symptoms in patients with RA.
Purpose
The aim of this study was to assess the efficacy of ESMR in the improvement of myocardial perfusion and symptoms in patients with RA.
Methods
Patients with RA despite optimal medical therapy and not suitable for further myocardial revascularization were enrolled and underwent ESMR. Characteristics such as angina class scores (CCS class score), nitroglycerin consumption and hospitalization rate among cases (patients with RA who received ESMR) and controls (patients with RA who did not receive ESMR) were compared at baseline and 6 months after ESMR therapy. In patients receiving ESMR the effect of on cardiac perfusion was assessed at six months.
Results
Among screened patients, 159 met the inclusion/exclusion criteria. 151 patients were enrolled in the present study and 121 treated with ESMR. There were 121 patients in the treatment group and 29 patients in the control group. The mean age of the patients was 70±8.8 years in the case group and 71±5.3 years in the control group. Other characteristics were similar in both groups. After ESMR myocardial perfusion by SPECT significantly improved: mean SSS was reduced from 21.2±9.42 to 14.2±10, with a 33% relative reduction (p=0.0001). Clinical follow up of both group demonstrated a significant improvement CCS class score at six months (1.5±0.6 in treatment and 1.92±0.69 in controls; p 0.0013) a significant improvement NYHA class score (1.4±0.6 in cases and 1.73±0.59 in controls; p 0.008); also, nitroglycerin consumption (29% in case cases, and 44.8% in controls; P 0.15) and hospitalization rate were reduced in the treatment group compared to control (16% vs. 37.9%; P 0.02).
Clinical outcome of two groups at 6 months follow up Treatment group (n=121) Control group (n=29) p CCS class 1.5±0.6 1.92±0.7 <0.001 NYHA class 1.4±0.6 1.7±0.6 <0.008 Nitrates uptake 35 (29%) 13 (45%) <0.15 Admission to emergency department 20 (16%) 11 (38%) <0.02
SPECT results after 6 months follow up
Conclusion
ESMR therapy is a non-invasive safe and potentially effective new option for patients with refractory angina. This study confirms the beneficial effect of ESMR therapy on cardiac symptoms, myocardial perfusion and hospitalizations in patients with refractory angina.

Abstract
Abstract
Introduction
Incidence and predictors of adverse events after dual antiplatelet therapy (DAPT) cessation in patients treated with ultrathin stents in unprotected left main (ULM) or coronary bifurcation remain undefined.
Methods
All consecutive patients presenting with a critical lesion of an ULM or a lesion involving a main coronary bifurcation and treated with very thin strut stents were included. MACE (a composite end point of cardiovascular death, myocardial infarction (MI), target lesion revascularization (TLR) and stent thrombosis (ST) was the primary endpoint, while target vessel revascularization (TVR) was the secondary endpoint. Moreover, type and occurrence of ST and occurrence of ST, CV death and MI during DAPT or after DAPT discontinuation were also evaluated. All analyses were performed according to length of DAPT dividing the patients in 3 groups: short DAPT (3-months), intermediate DAPT (3–12 months) and long DAPT (12-months).
Results
117 patients were discharged with an indication for DAPT≤3 months (median 1:1–2.5), 200 for DAPT between 3 and 12 months (median 8:7–10) and 1958 with 12 months DAPT. After 12.8 months (8–20), MACE was significantly higher in the 3-month group compared to 3–12 and 12-month groups (9.4% vs. 4.0% vs. 7.2%, p≤0.001), mainly driven by MI (4.4% vs. 1.5% vs. 3%, p≤0.001) and overall ST (4.3% vs. 1.5% vs. 1.8%, p≤0.001). ST post DAPT cessation were comparable (1.7% vs. 0% vs. 0.7%, p=0.42) with a median time to ST post DAPT discontinuation of 1.67 months (0.48–4.7). At multivariate analysis, DAPT of 12-months compared to 3-months reduces the risk of overall ST (OR 0.103: 0.019–0.0563, 95% CI) while only a trend was noted for DAPT between 3 and 12 months (OR 0.61: 0.186–2.005, 95% CI). When analysed by stent strategy a 2-stent strategy predicted ST post DAPT cessation (OR 3.241: 1.048–10.026, 95% CI), which was reduced by use of FKB (OR 0.101:0.01–0.872, 95% CI).
Conclusion
Even stents with very thin strut when implanted in real-life ULM or coronary bifurcation patients discharged with short DAPT have a relevant risk of ST, which remains high although not significant after DAPT cessation. The correct identification before PCI of the more fragile patients who may receive a shorter DAPT regimen could help identify the safest PCI technique: provisional stenting and use of final kissing balloon (FKB) are the safest options.

Abstract
Abstract
Background
The optimal antithrombotic therapy strategy in patients undergoing PCI who need OAC is currently debated.
Purpose
To determine the best regimen in terms of safety and efficacy.
Methods
We performed a meta-analysis of RCT and adjusted results reporting outcomes of patients who underwent PCI and were on TT or DAPT or DT. All-cause death was the primary end point, while MACE was the secondary outcome, along with its individual components, and major bleedings.
Results
15 studies encompassing 27070 patients were included. After a follow up of 12 (11–14) months, TT reduced all-cause death compared to DAPT (OR 0.52, 0.35–0.78), mainly driven by a lower incidence of MI (OR 0.81, 0.69–0.85) and stroke (OR 0.76, 0.56–1.03) despite higher rates of major bleedings (OR 2.81, 1.54–5.12). Comparing TT vs. DT with warfarin, all-cause death was non-significantly different (OR 1.23, 0.60–2.53), nor MI (OR 0.77, 0.23–2.59) and stroke (OR 4.01, 0.80–20.07), while major bleeding was increased with TT (OR 2.40, 1.34–4.38). When compared to DT with NOACs, TT did not reduce risk of MI (OR 0.96, 0.67–1.36) or stroke (OR 0.82, 0.55–1.24), but increased major bleedings (OR 1.98, 1.43–2.73). The non-randomized comparison between DT with warfarin and DT with NOACs showed a neutral effect on death and major bleedings, with similar rates also of MI (OR 0.47, 0.20–1.11, all CI 95%).
Conclusion
Double therapy with warfarin or with NOAC plus a single antiplatelet agent reduces the risk of major bleeding compared to triple therapy, with a neutral impact of subsequent ischemic events.

Abstract
Abstract
Introduction
Brugada syndrome (BrS) cause about 20% of sudden cardiac death (SCD) in young healthy adults. Nearly 20% of Brugada patients develop supraventricular arrhythmias, mostly atrial fibrillation (AF). But whether lone AF may be the first clinical manifestation in young patients with latent BrS remains unclear.
Purpose
To estimate the prevalence and clinical significance of latent Brugada ECG pattern in young population (age ≤45 years) with lone AF.
Methods
A total of 78 patients with lone atrial fibrillation (mean age 35±7) were selected from 111 young patients with juvenile atrial fibrillation (age ≤45 years) between January 2015 and November 2017. All patients were clinically evaluated. Moreover 12 lead-24H Holter ECG and pharmacological class 1C antiarrhythmic drug (AAD) test were done for high suspicious cases of Brugada ECG. The diagnosis of Brugada ECG pattern was established according to the second consensus report criteria 2005 and since 2013, according to HRS/EHRA/APHRS expert consensus statement.
Results
According to the study protocol, we considered two groups of patients, group 1: 13 patients (16.7%; mean age 37±8) were diagnosed with type 1 Brugada ECG pattern (3 during class 1C AADs therapy and 10 induced by class 1C AAD test), group 2: 65 patients (83%; mean age 35±7) diagnosed as lone AF without type 1 Brugada ECG. The clinical characteristics of the two groups are described in table 1. Regarding to group 1, two patients had positive electrophysiological study with subsequent ICD implantation and genetic test for SCN5A mutation was positive in 3 patients.
Table 1. G1, G2 clinical characteristics Patients characteristics Group 1 (n=13) Group 2 (n=65) P value Mean age (years) 37±8 35±7 0.42 Gender (Male %) 7 (54%) 54 (83%) 0.02 Family history of BrS 2 (15%) 0 (0%) 0.03 Family history of SCD 1 (8%) 1 (1.5%) 0.20 Syncope 4 (31%) 5 (8%) 0.02 Sick Sinus Syndrome 1 (8%) 7 (11%) 0.70 Paroxysmal AF 12 (92%) 54 (83%) 0.40 Suspected basal ECG for BrS 13 (100%) 28 (43%) <0.01 Statistical test is considered significant when p value <0.05.
Conclusions
Up to our knowledge this study is the first one that estimate the prevalence of latent BrS in juvenile lone AF patients. Young patients with lone AF had a high prevalence of latent BrS. Syncope, family history of SCD and family history of BrS are significant indicators of the presence of latent BrS in young patients with lone atrial fibrillation.

Abstract
Abstract
Introduction
Safety and efficacy of prasugrel and ticagrelor in real-life ACS (Acute Coronary Syndrome) with renal dysfunction remain to be established.
Methods
Consecutive patients from RENAMI and BLEEMACS were stratified according to renal function and estimated glomerular filtration rate (eGFR<60 mL/min/1.73 m2). Myocardial infarction (MI) and BARC major bleedings (MB; BARC type 3 or 5) were the primary end-point. Independent impact of clopidogrel, prasugrel and ticagrelor were evaluated with Cox multivariate analysis.
Results
19255 patients were enrolled (mean eGFR: 90±39 ml/min/1.73m2). Patients with eGFR<60 mL/min/1.73m2, constituted the 12.9% of the population (2490 pts). After a mean follow up of 13±5 months, the global incidence of re-AMI was of 5.8% and 2.9% in patients with and in those without eGFR<60 mL/min/1.73m2 (p<0.0001) respectively. MB occurred in 5.7% and 3% (p<0.0001). At Cox multivariate analysis, clopidogrel compared to prasugrel and ticagrelor was associated with increased risk of MI both in those with eGFR>60 mL/min/1.73m2 (HR=3.3: 2.4–4.4, p<0.0001) as well as in patients with eGFR<60 mL/min/1.73m2 (HR=10.04: 3.1–32.3, p<0.0001). In contrast, both prasugrel (HR=0.07: 0.01–0.54, p=0.01) and Ticagrelor (HR=0.36: 0.16–0.81, p=0.01) were associated with decreased risk of MI in the latters. DAPT with ticagrelor or prasugrel did not increased risk of MB in patients with eGFR<60 mL/min/1.73m2, while in patients with eGFR>60 mL/min/1.73m2, ticagrelor was associated to a slightly higher risk of MB (HR=1.43: 1.09–1.89, p=0.009).
Conclusion
In ACS patients with eGFR<60 mL/min/1.73m2, prasugrel and ticagrelor are associated with lower risk of recurrent MI without significant increase in the risk of MB.

Abstract
Abstract
Background
Thinner stent struts of new DES (drug eluting stent) are associated with shorter time of reendothelialization, a reduction of shear stress and inflammation of coronary walls. Despite this great innovations their clinical safety and efficacy in challenging scenarios as non left main bifurcation coronary lesions has not been tested.
Methods
RAIN is a multicenter registry enrolling patients treated on bifurcated coronary lesions and left main with thin-strut DES. Baseline characteristics and procedural data were recorded. Target lesion revascularization (TLR) was the primary endpoint, whereas major adverse clinical events (MACE; composite of all-cause death, myocardial infarction (MI), target vessel revascularization (TVR), TLR and stent thrombosis (ST)) along with its single components were the secondary endpoints. A multivariate analysis to identify predictors of TLR and sub-analysis according to stenting strategy (provisional vs 2-stent technique), use of final kissing balloon (FKB) and IVUS/OCT optimization were performed.
Results
Data from 1803 patients (59% ACS, 61% stable CAD) treated on bifurcations were retrospectively evaluated. Follow up was available for 1685 (94%) patients for a median of 12 months (IQR 7–18). TLR occurred globally in 2.5% of cases (2.2% in provisional stenting, 3.5% in 2-stent technique). The rate of MACE was 9.4%, whereas all-cause death and MI, occurred in 4.1% and 3.2% of cases respectively. TVR and definite ST incidence were 3.7% and 1.1%. At multivariate analysis, chronic kidney disease (CKD) negatively influenced the main endpoint (HR 1.95, 95% CI 1.06–3.6, p=0.03), whereas post-dilatation (HR 0.56, 95% CI 0.3–0.93, p=0.04) and provisional stenting resulted being protective factors. FKB reduced TLR occurrence at FU only in 2-stent technique (p=0.03), whereas intracoronary imaging (performed in 29% of patients) were uninfluential.
Conclusion
Very thin-strut DES represents a highly effective solution in bifurcation lesions. The risk of TLR is reduced by post-dilatation and provisional stenting. FKB is recommended in 2-stent technique, whereas further studies are required to address the impact of intracoronary imaging in this setting.

Abstract
BACKGROUND Brugada syndrome is characterized by ST-segment elevation in the right precordial leads and an increased risk of sudden cardiac death (SCD). Fundamental questions remain on the best strategy for assessing the real disease-associated arrhythmic risk, especially in asymptomatic patients. The aim of the present study was to evaluate the prognosis and risk factors of SCD in Brugada syndrome patients in the FINGER (France, Italy, Netherlands, Germany) Brugada syndrome registry. METHODS AND RESULTS Patients were recruited in 11 tertiary centers in 4 European countries. Inclusion criteria consisted of a type 1 ECG present either at baseline or after drug challenge, after exclusion of diseases that mimic Brugada syndrome. The registry included 1029 consecutive individuals (745 men; 72%) with a median age of 45 (35 to 55) years. Diagnosis was based on (1) aborted SCD (6%); (2) syncope, otherwise unexplained (30%); and (3) asymptomatic patients (64%). During a median follow-up of 31.9 (14 to 54.4) months, 51 cardiac events (5%) occurred (44 patients experienced appropriate implantable cardioverter-defibrillator shocks, and 7 died suddenly). The cardiac event rate per year was 7.7% in patients with aborted SCD, 1.9% in patients with syncope, and 0.5% in asymptomatic patients. Symptoms and spontaneous type 1 ECG were predictors of arrhythmic events, whereas gender, familial history of SCD, inducibility of ventricular tachyarrhythmias during electrophysiological study, and the presence of an SCN5A mutation were not predictive of arrhythmic events. CONCLUSIONS In the largest series of Brugada syndrome patients thus far, event rates in asymptomatic patients were low. Inducibility of ventricular tachyarrhythmia and family history of SCD were not predictors of cardiac events.

Abstract
OBJECTIVES The purpose of this study was to verify in a long-term follow-up whether frequent monomorphic right ventricle extrasystoles may progress to arrhythmogenic right ventricular dysplasia (ARVD). BACKGROUND Frequent monomorphic right ventricle extrasystoles are generally considered benign. However, in patients with this pattern, cardiac magnetic resonance (MR) has recently shown anatomical and functional abnormalities of the right ventricle. METHODS Sixty-one patients who had been classified by noninvasive examinations as having frequent idiopathic right ventricle ectopy were contacted after 15 +/- 2 years (12 to 20) and submitted to clinical examination, electrocardiogram (ECG), Holter monitoring, stress test, signal averaged ECG, echocardiography and, in 11 patients, cardiac MR. The primary end point was to ascertain the presence of cases of sudden death or progression to ARVD. RESULTS At the end of the follow-up, 55 patients were alive; six died, none of sudden death; eight stated to be well but refused further examinations. The 47 patients examined had normal ECG; in 24 patients (51%), extrasystoles were no longer present at Holter monitoring; late potentials were present in up to 15% of the patients; the right ventricle was normal at echocardiography. In 8 of 11 patients (73%), cardiac MR showed focal fatty replacement and other abnormalities of the right ventricle. CONCLUSIONS In this long-term follow-up study, no patient died of sudden death nor developed ARVD; two-thirds of the patients were asymptomatic, and, in half of the patients, ectopy had disappeared. Focal fatty replacement in the right ventricle was present in most.

Abstract
Clinical electrophysiology has not yet clearly defined atrial features that can predict spontaneous occurrence of atrial fibrillation (AF). The aim of this work was to identify atrial electrophysiological features that can distinguish Wolff-Parkinson-White patients with spontaneous AF from those without this arrhythmia. Sixty-nine patients with Wolff-Parkinson-White were divided into three groups: group I (16 patients) with spontaneous AF; group II (35 patients) with reciprocating tachycardia but not AF; and group III (18 patients) asymptomatic without documented arrhythmias. Atrial effective refractory periods (ERPs) and intraatrial conduction times in response to premature extrastimuli were analyzed. The latter were evaluated as the A1A2 interval minus the correspondent S1S2 interval (A1A2-S1S2), S1A2 and the interval A1A2 following the shortest S1S2 producing atrial activation (FRP'). All the parameters have been evaluated in two atrial sites and at two atrial pacing cycle lengths (600 and 400 ms). For all the parameters, the difference ("gradient") was calculated between the values of the same parameter measured at the atrial pacing cycle length of 600 ms and that found at the atrial pacing cycle length of 400 ms in the same recording site in each patient was calculated. Atrial ERP did not differ significantly in the three groups. Intraatrial conduction parameters, evaluated in the high right atrium (HRA), were longer when measured at an atrial pacing of 400 ms and showed a lack of rate adaptation in patients with spontaneous AF. In group I patients in particular, FRP' became longer with the increase of atrial rate, while in groups 2 and 3, it usually shortened. The mean gradient of HRA FRP' was -15.0 +/- 19 ms in group I as compared to 5.7 +/- 13 ms in group II and 6.4 +/- 13 ms in group III (P < 0.001); sensitivity, specificity, and negative predictive value of a negative gradient in the identification of patients with spontaneous AF, were, respectively, 83%, 75%, and 93%. Patients from groups 2 and 3 did not differ in any of the analyzed parameters. Patients with Wolff-Parkinson-White and spontaneous AF showed prolonged intraatrial conduction times and a different behavior in response to modification of heart rate.

Abstract
BACKGROUND Idiopathic verapamil-responsive left ventricular tachycardia (IVRLVT) is a rare, well known form of ventricular tachycardia. Issues concerning long-term prognosis, drug prophylaxis and non-pharmacological therapy are rarely reported in the literature. We report the long-term follow-up, the efficacy of various drugs in the prophylaxis and the role of catheter ablation in a large group of patients with IVRLVT. METHODS AND RESULTS This retrospective study involves 37 patients with a mean age of 28.3 +/- 14.8 years at first IVRLVT episode. The tachycardia morphology was typically with a right bundle-branch block configuration in all cases, with left axis deviation in 33 and right axis deviation in 5 (one patient had the 2 morphologies). Four patients had a mitral valve prolapse; the remaining 33 patients had neither clinical nor echocardiographic signs of heart disease. Only sporadic ventricular extrasystoles were detected at Holter monitoring in 73% of cases; 30% of patients had positive criteria for the presence of late potentials at signal averaged ECG. During electrophysiologic study, the tachycardia could be easily induced in 91% of patients. Mean follow-up is 7.3 +/- 4.7 years; all patients are alive at the end of follow-up. A mean of 2.3 +/- 1.2 drugs was prescribed in 35 patients (94.6%); betablockers were effective in 66% of the cases, verapamil in 20%, class I drugs in 22%, class III drugs in 15%. Both the 2 patients, who never received prophylaxis, and the 4 who stopped medication, utilize verapamil in case of recurrences. Eight patients were submitted to catheter ablation, with DC shock the first 2 patients, with RF energy from the third on; all but one (with DC shock) were successfully cured. CONCLUSIONS Long-term follow-up confirmed the good prognosis of this form of ventricular tachycardia; a new insight that has been addressed about prophylaxis is the high efficacy of betablockers in preventing relapse and the poor efficacy of verapamil per os in chronic prophylaxis. Radiofrequency catheter ablation is effective and safe, using the earliest ventricular potential and the pace-mapping reproducing the same morphology of the tachycardia in all the 12 leads as a marker to identify the site of RF application, and may be proposed to all patients suffering from frequent episodes of IVRLVT.

Abstract
OBJECTIVES This study evaluated accessory pathway location, its relation to retrograde P wave polarity on the surface electrocardiogram and radiofrequency ablation efficacy and safety in a large group of patients with permanent junctional reciprocating tachycardia. BACKGROUND Permanent junctional reciprocating tachycardia is an uncommon form of reciprocating tachycardia, almost incessant from infancy and usually refractory to drug therapy. It is characterized by RP > PR interval and usually by negative P waves in leads II, III, aVF and V4 to V6. Retrograde conduction occurs through an accessory pathway with slow and decremental properties. Although this accessory pathway has been classically located in the posteroseptal zone, other locations have been recently reported. METHODS The study included 32 patients (20 men, 12 women, mean [+/- SD] age 29 +/- 15 years) with a diagnosis of permanent junctional reciprocating tachycardia confirmed at electrophysiologic study. Seven patients had depressed left ventricular function. Radiofrequency energy was applied at the site of the earliest retrograde atrial activation during tachycardia. RESULTS There were 33 accessory pathways. The site of the earliest retrograde atrial activation was posteroseptal in 25 patients (76%), midseptal in 4 (12%), right posterior in 1 (3%), right lateral in 1 (3%), left posterior in 1 (3%) and left lateral in 1 (3%). Thirty pathways were ablated with a right approach; in 11 patients with posteroseptal pathway the ablation was performed through the coronary sinus. Three pathways were ablated with a left approach. Positive retrograde P wave in lead I suggested that ablation could be performed from the right side; if negative, it did not exclude ablation from this approach. All the accessory pathways were successfully ablated, with a median of 3 and a mean of 5.6 +/- 5 radiofrequency applications of 70 +/- 26 s in duration. In two patients with the accessory pathway in the midseptal zone, a transient second- and third-degree atrioventricular block, respectively, was observed after ablation. At a mean follow-up of 18 +/- 12 months, 31 patients (97%) are asymptomatic without antiarrhythmic therapy (95% confidence interval [CI] 84% to 99%). Recurrences were observed in four patients (13%) (95% CI 4% to 29%), three of whom had the accessory pathway ablated successfully at a second session. All patients with depressed left ventricular function showed a marked improvement after successful ablation. CONCLUSIONS In our experience, most of the patients with permanent junctional reciprocating tachycardia had posteroseptal pathways; all these pathways were ablated from the right side. P wave configuration may be helpful in suggesting the approach to the site of ablation. Catheter ablation using radiofrequency energy is an effective therapy for permanent junctional reciprocating tachycardia.

Abstract
Long-term prognosis, pharmacological prophylaxis and transcatheter ablation in a large group of patients with idiopathic verapamil-responsive left ventricular tachycardia (IVRLVT) are reported in this study. Thirty-three patients with a mean age of 27 +/- 16 years at their first IVRLVT episode, were studied retrospectively. Ventricular tachycardia was of the right bundle branch block morphology in all cases, with left axis deviation in 29 and right axis deviation in five (one patient had the two morphologies). Mitral valve prolapse was present in four patients; no heart disease was found in the remaining 29. Ventricular tachycardia could be electrophysiologically induced in 90% of the patients; Holter monitoring showed only sporadic ventricular extrasystoles in 76%; late potentials were found in 33% of the cases. At the end of a follow-up of 5.7 +/- 4.7 years, no patient had died. Thirty-one patients (94%) received a mean of 2.5 +/- 1.2 drugs; beta-blockers were effective in 71% of the cases, verapamil in 25%, class 1 drugs in 22%, class 3 drugs in 18%. Two patients who never received prophylaxis and four in whom it was stopped, were controlled with verapamil in case of recurrence. Six patients underwent catheter ablation; two with DC shock in whom it was successful in one, and four with radiofrequency energy, with a total success rate. The good prognosis of IVRLVT has been confirmed in a long-term follow-up; a new finding is the high efficacy of beta-blockers for prophylaxis. Radiofrequency transcatheter ablation is an effective and safe therapy for patients with symptoms not controlled by drug treatment.

Abstract
We investigated the clinical, electrophysiological, haemodynamic and angiographic aspects of four patients (two men and two women, aged 31-46 years) who developed complete heart block 13-20 years after therapeutic irradiation of the chest for Hodgkin's disease. The initial cardiac symptom was syncope in three, effort intolerance in one. The electrocardiogram recorded third-degree atrioventricular block in three patients, right bundle branch block and posterior fascicular block in one. The electrophysiological study, performed in three cases, showed that the block was infranodal in two. Three patients had significant coronary arterial stenoses, that involved the ostia in two. All patients had mild-to-moderate aortic and mitral regurgitation. One patient had haemodynamic signs of constriction. Another patient had recurrent pericardial effusions. All had echocardiographic evidence of a thickened pericardium. Cardiac involvement can be extensive in patient with radiation-induced heart block. Because coronary artery disease can be particularly severe, coronary angiography appears to be warranted in such patients.

Abstract
PATIENTS Fifty-two patients with Wolff-Parkinson-White syndrome underwent transcatheter ablation. All patients were symptomatic. Eighteen had documented episodes of atrial fibrillation, 14 of which also had reentrant tachycardias; the remaining 34 had only episodes of reentrant tachycardias. Forty-nine patients had both anterograde and retrograde conduction through the accessory pathway; 3 had retrograde conduction alone; 2 patients had 2 accessory pathways and 1 had 3. All patients were resistant or intolerant to at least 2 antiarrhythmic drugs. METHODS All patients were treated with radiofrequency current. Ablation was considered successful if the anterograde and retrograde conduction were completely abolished. Ablation was considered unsuccessful if ablation of only 1 pathway in patients with 2 or more accessory pathways and/or modification of the accessory pathway conduction without interruption was achieved. RESULTS Accessory pathway ablation was successfully performed in 46 out of 52 patients (88%). Fifty out of 56 accessory pathways were effectively ablated (89%). Thirty-eight required a single session of ablation and 8 additional patients were successfully ablated during a second session. The number of radiofrequency current applications ranged from 2 to 13 (mean 4.1 +/- 2.5). The mean duration of the sessions was 4.30 +/- 1.50 hours (range 2.30 to 9). The mean radiation exposure for session was 55 +/- 25 minutes (range 20 minutes to 2.30 hours). Complications were observed in 2 out of 52 patients. One patient had a transient II degree type 1 atrioventricular block; another patient with severe arterial hypertension had a mild hemorrhagic stroke with complete neurological remission. FOLLOW-UP. Forty-five out of the 46 patients in whom ablation was successful were asymptomatic for arrhythmias during a mean follow-up of 8 months (range 4 to 16), without antiarrhythmic treatment, and without reappearance of preexcitation. One patient showed reappearance of preexcitation at electrocardiogram one month after the ablation, followed by an episode of reentrant tachycardia; this patient underwent a second successful ablation session. CONCLUSIONS Our results show that ablation techniques have high success rates with no serious complications.

Abstract
Patients with Wolff-Parkinson-White (WPW) pattern of ventricular pre-excitation may develop paroxysmal re-entrant tachyarrhythmias through the Kent bundle and, less commonly, atrial fibrillation. WPW patients are at risk of sudden death when a rapid ventricular response occurs during atrial fibrillation due to conduction through the accessory pathway. Conduction properties of the accessory pathway and atrial vulnerability, which is the propensity to develop atrial fibrillation, are important parameters for evaluation in these patients. The former can be assessed by means of noninvasive tests, such as stress and pharmacological tests, and with electrophysiological study; the latter only by electrophysiological study. There is no indication for treatment of asymptomatic patients. Antiarrhythmic prophylaxis is required in patients with previous episodes of atrial fibrillation with rapid ventricular response, in patients with paroxysmal re-entrant tachycardias and rapid conduction through the accessory pathway, and in patients with frequent episodes of re-entrant tachycardias of long duration. Vaughan-Williams class IC anti-arrhythmic drugs (propafenone, flecainide) are the first choice for drugs in patients with rapid anterograde conduction through the accessory pathway due to their high efficacy and low incidence of adverse effects, while beta-blockers (atenolol, nadolol) are indicated for patients with re-entrant tachycardias and low conduction capacity through the bypass tract. When pharmacological therapy is ineffective, surgical or catheter ablation of the accessory pathway may be considered.

Abstract
Between 1985 and 1990, 1242 patients with supraventricular arrhythmias were followed-up at our Institution. Six hundred and twenty patients had atrial fibrillation or flutter; 7 of them (1%) underwent modulation of atrioventricular conduction. Four hundred and twenty-eight patients had ventricular preexcitation; in 23 (5%) surgical or transcatheter ablation of an accessory pathway were performed. Atrioventricular node reentrant tachycardias were diagnosed in 111 patients; 8 patients (7%) underwent antitachycardia pacemaker implantation. Surgical and catheter ablative techniques eliminate the substrate of the tachycardia; death and complete A-V block (paraseptal pathways) are at this moment rarely reported. Antitachycardia pacemakers do not offer a definitive therapy. For their safeness and effectiveness they are still indicated in patients with A-V node reentrant tachycardias, until technological development will reduce the risks of ablative techniques.

Abstract
An intracavitary electrophysiological study was carried out on 103 patients with Wolff-Parkinson-White (WPW), 23 symptomatic patients had documented episodes of atrial fibrillation, 54 symptomatic patients had atrioventricular reentrant tachycardias, and 26 asymptomatic. Patients were examined for the relation between spontaneous atrial fibrillation and atrial vulnerability, defined as the possibility to induce sustained (greater than 1 minute) episodes of atrial fibrillation with a stimulation protocol excluding atrial bursts. Atrail fibrillation induction was attempted by single and double atrial extrastimuli during pacing at two different cycle lengths and incremental atrial pacing. Sustained atrail fibrillation was induced in 65% of the patients with spontaneous atrial fibrillation, and in 13% of the symptomatic patients with documented episodes of atrioventricular reentrant tachycardias and in 15% of the asymptomatic patients (P less than 0.0005). Atrial vulnerability was higher in patients with spontaneous atrial fibrillation than in patients without this arrhythmia. No significant difference was observed between symptomatic without atrial fibrillation and asymptomatic patients.

Abstract
The purpose of this study was to examine the relation between spontaneous atrial fibrillation and the induction of atrial tachyarrhythmias during electrophysiologic study in patients with Wolff-Parkinson-White, with and without atrial fibrillation. Intracavitary electrophysiologic study was performed on 115 patients, 27 with spontaneous atrial fibrillation (group 1), 57 symptomatic due to AV re-entrant tachycardias, without spontaneous atrial fibrillation (group 2) and 31 asymptomatic (group 3). Induction of atrial fibrillation was attempted by using single and double atrial extrastimuli during atrial pacing at 2 different cycle lengths and by incremental atrial pacing (protocol A). When atrial fibrillation was not obtained, atrial bursts were added (protocol B). Atrial fibrillation or flutter were induced in 81% of group 1.54% of group 2 and 55% of group 3 patients (p less than 0.05), using protocol A. They were induced in 100, 75 and 71%, respectively (p = 0.01), with protocol B. Considering only sustained (greater than 1 minute) episodes, atrial fibrillation or flutter were induced in the three groups with protocol A in 74, 33 and 32% of the patients, respectively (p less than 0.001). The difference in the three groups was even greater when atrial fibrillation was considered separately from atrial flutter. The reason for this was that atrial fibrillation was induced in two thirds of group 1 patients, while only about 15% of patients without spontaneous atrial fibrillation had this arrhythmia induced. Our results suggest that the induction of sustained atrial fibrillation is a useful parameter to separate Wolff-Parkinson-White patients with from those without spontaneous atrial fibrillation. Due to the low specificity of the analysis of the shortest R-R interval during induced atrial fibrillation for the identification of the patients at risk of sudden death, the induction of sustained atrial fibrillation could be proposed as an additional parameter. This would improve the specificity of electrophysiologic study.

Abstract
After a brief revision about the long QT syndrome, we report the case of a 52 year old man admitted to hospital for a syncopal attack. His electrocardiogram was considered normal: sinus bradycardia and U waves were recorded. The echocardiogram revealed anterior mitral leaflet redundancy and possible tricuspid prolapse. During the atropine test, after a normal increment of sinus frequency, 2 runs of self-limited torsade de pointes appeared. The electrocardiogram showed lesion wave at first, and then prolonged QT. During the intracavitary study, premature ventricular stimulation caused torsade de pointes. After propranolol iv it was no more possible to induce major ventricular arrhythmias anymore. Coronarography was normal. Nadolol therapy was begun. On 6 months follow-up the patient is asymptomatic.

Abstract
Noninvasive stress and pharmacologic tests with procainamide and propafenone were studied as methods to identify patients with Wolff-Parkinson-White syndrome (WPW) who would otherwise be judged at risk of sudden death on the basis of electrophysiologic criteria: the shortest RR interval during induced atrial fibrillation less than or equal to 250 ms or accessory pathway anterograde effective refractory period less than or equal to 250 ms. Sixty-five patients were studied. Twenty-four patients fulfilled the electrophysiologic risk criteria (group A) and 41 patients fulfilled none of these criteria (group B). Persistence of preexcitation during stress test showed a sensitivity of 96% and a specificity of 17% to identify group A patients; its positive predictive value was 40% and negative predictive value 88%. With both procainamide and propafenone tests persistence of preexcitation identified group A patients with a sensitivity of 96% and a specificity of 51%; their positive and negative predictive value were, respectively, 53 and 95%. Stress and pharmacologic tests have good sensitivity and negative predictive value, but low specificity and positive predictive value.

Abstract
It is well known that in patients with Wolff-Parkinson-White (W.P.W.) adrenergic activity stimulation induced by exercise or isoproterenol I.V. infusion shortens the anterograde effective refractory period (E.R.P.) of the accessory pathway. Our purpose was to evaluate whether the upright position produces similar changes on the electrophysiologic properties of the accessory pathway and influences reciprocating tachycardias induction. In 18 patients, with W.P.W. syndrome, who underwent electrophysiologic study, we determined the anterograde E.R.P. of the accessory pathway and attempted to induce a reciprocating tachycardia in the supine and in the upright position. In 13 patients (72%) the anterograde E.R.P. of the accessory pathway shortened in the upright position (303 +/- 104 msec vs 331 +/- 123 msec; p less than 0.001); in 4 patients (22%) it was unchanged; in 1 patient was not defined, being inferior to the atrium E.R.P. We were able to induce a reciprocating tachycardia in 3 patients in the supine position, in 6 patients in the upright position. Electrophysiologic testing in the upright position improves the evaluation of the accessory pathway electrophysiologic properties.
