| 1 | Electrical storm: A clinical and electrophysiological overview显示文摘Electrical storm(ES) is a clinical condition characterized by three or more ventricular arrhythmia episodes leading to appropriate implantable cardioverterdefibrillator(ICD) therapies in a 24 h period. Mostly, arrhythmias responsible of ES are multiple morphologies of monomorphic ventricular tachycardia(VT), but polymorphic VT and ventricular fibrillation can also result in ES. Clinical presentation is very dramatic in most cases, strictly related to the cardiac disease that may worsen electrical and hemodynamic decompensation. Therefore ES management is challenging in the majority of cases and a high mortality is the rule both in the acute and in the long-term phases. Different underlying cardiomyopathies provide significant clues into the mechanism of ES, which can arise in the setting of structural arrhythmogenic cardiomyopathies or rarely in patients with inherited arrhythmic syndrome, impacting on pharmacological treatment, on ICD programming, and on the opportunity to apply strategies of catheter ablation. This latter has become a pivotal form of treatment due to its high efficacy in modifying the arrhythmogenic substrate and in achieving rhythm stability, aiming at reducing recurrences of ventricular arrhythmia and at improving overall survival. In this review, the most relevant epidemiological and clinical aspects of ES, with regard to the acute and long-term follow-up implications, were evaluated, focusing on these novel therapeutic strategies of treatment. | Sergio Conti Salvatore Pala Viviana Biagioli Giuseppe Del Giorno Martina Zucchetti Eleonora Russo Vittoria Marino Antonio Dello Russo Michela Casella Francesca Pizzamiglio Valentina Catto Claudio Tondo Corrado Carbucicchio | 2015 | World Journal of Cardiology2015,7,9: | 9 |

| 11 | Electrical storm in systemic sclerosis: Inside the electroanatomic substrate显示文摘We report the case of a 63-year-old woman affected by a severe form of systemic scleroderma with pul-monary involvement(interstitial fibrosis diagnosed by biopsy and moderate pulmonary hypertension) and cardiac involvement(paroxysmal atrial fibrillation, right atrial flutter treated by catheter ablation, ventricular tachyarrhythmias, previous dual chamber implantable cardioverter defibrillator implant). Because of recurrent electrical storms refractory to iv antiarrhythmic drugs the patient was referred to our institution to undergo catheter ablation. During electrophysiological proce-dure a 3D shell of cardiac anatomy was created with intracardiac echocardiography pointing out a significant right ventricular dilatation with a complex aneurysmal lesion characterized by thin walls and irregular multiple trabeculae. A substrate-guided strategy of catheter ab-lation was accomplished leading to a complete electri-cal isolation of the aneurism and to the abolishment of all abnormal electrical activities. The use of advanced strategies of imaging together with electroanatomical mapping added important information to the complex arrhythmogenic substrate and improved efficacy and safety. | Michela Casella Corrado Carbucicchio Eleonora Russo Francesca Pizzamiglio Paolo Golia Sergio Conti Fabrizio Costa Antonio Dello Russo Claudio Tondo | 2014 | World Journal of Cardiology2014,6,10: | 0 |
| 12 | Manifold benefits of choosing a minimally fluoroscopic catheter ablation approach显示文摘We report the case of a 14-year-old boy with ventricular preexcitation. A standard, fluoroscopy guided, ablation procedure was successfully performed in a postero-midseptal region with a total fluoroscopy time of about 45 min (2430 cGy.cm2). A few hours after the procedure, preexcitation reappeared. A second ablation procedure was scheduled using the EnSite NavXTM mapping system. During mapping along the tricuspid groove, preexcitation suddenly disappeared due to mechanical 'bumping' of the accessory pathway and it did not recover over the next 30 min. As per our routine practice, the phase of geometry reconstruction has been continuously recorded by the system; thus, an off-line analysis allowed to pinpoint the site of earliest activation and the site of mechanical bumping, where radiofrequency obtained the accessory pathway ablation. The second procedure was performed without using fluoroscopy at all. Thanks to the geometry reconstruction, the procedure was completely successful thus avoiding a further rehospitalization. | Michela Casella Antonio Dello Russo Gaetano Fassini Daniele Andreini Pasquale De Iuliis Saima Mushtaq Stefano Bartoletti Stefania Riva Claudio Tondo | 2013 | World Journal of Cardiology2013,5,2: | 0 |
| 13 | Difficult case of a trans-septal puncture: Use of a “SafeSept” guidewire显示文摘A 69-year-old man was admitted to our center to undergo catheter ablation of paroxysmal atrial fibrillation refractory to antiarrhythmic drug therapy. This procedure required access to the left atrium through the interatrial septum. During hospitalization, the patient performed routinely pre-procedure transthoracic echocardiography and gadolinium-enhanced cardiac magnetic resonance showing a normal anatomy of both the fossa ovalis and the interatrial septum. Access to the left atrium proved difficult and several unsuccessful attempts to perform the trans-septal puncture were made under both fluoroscopy and intracardiac echocardiography guidance, even with radiofrequency energy delivery. Finally, trans-septal puncture was successfully carried out using a novel nitinol J-shaped 'Safe Sept' trans-septal guidewire, designed to cross the interatrial septum through the trans-septal needle thanks to a special sharp tip. Moreover, thanks to its rounded J shape that reduces the risk of atrial perforation, the 'Safe Sept' guidewire, when advanced into the left atrium, becomes atraumatic. | Martina Zucchetti Michela Casella Antonio Dello Russo Gaetano Fassini Corrado Carbucicchio Eleonora Russo Vittoria Marino Valentina Catto Claudio Tondo | 2015 | World Journal of Cardiology2015,7,8: | 0 |
| 14 | Collateral findings during computed tomography scan for atrial fibrillation ablation:Let's take a look around显示文摘The growing number of atrial fibrillation catheter ablation procedures warranted the development of advanced cardiac mapping techniques, such as image integration between electroanatomical map and cardiac computed tomography. While scanning the chest before catheter ablation, it is frequent to detect cardiac and extracardiac collateral findings. Most collateral findings are promptly recognized as benign and do not require further attention. However, sometimes clinically relevant collateral findings are detected, which often warrant extra diagnostic examinations or even invasive procedure, and sometimes need to be followed-up over time. Even though reporting and further investigating collateral findings has not shown a clear survival benefit, almost all the working groups providing data on collateral findings reported some collateral findings eventually coming out to be malignancies, sometimes at an early stage. Therefore, there is currently no clear agreement about the right strategy to be followed. | Francesco Perna Michela Casella Maria Lucia Narducci Antonio Dello Russo Gianluigi Bencardino Gianluca Pontone Gemma Pelargonio Daniele Andreini Nicola Vitulano Francesca Pizzamiglio Edoardo Conte Filippo Crea Claudio Tondo | 2016 | World Journal of Cardiology2016,8,4: | 0 |
