- Accessory Atrioventricular Pathways Refractory to Catheter Ablation Role of Percutaneous Epicardial Approach(2015) SCANAVACCA, Mauricio Ibrahim; STERNICK, Eduardo Back; PISANI, Cristiano; LARA, Sissy; HARDY, Carina; D'AVILA, Andre; CORREA, Frederico Soares; DARRIEUX, Francisco; HACHUL, Denise; MARCIAL, Miguel Barbero; SOSA, Eduardo A.Background-Epicardial mapping and ablation of accessory pathways through a subxiphoid approach can be an alternative when endocardial or epicardial transvenous mapping has failed. Methods and Results-We reviewed acute and long-term follow-up of 21 patients (14 males) referred for percutaneous epicardial accessory pathway ablation. There was a median of 2 previous failed procedures. All patients were highly symptomatic, 8 had atrial fibrillation (3 with cardiac arrest) and 13 had frequent symptomatic episodes of atrioventricular reentrant tachycardia. Six patients (28.5%) had a successful epicardial ablation. Five patients (23.8%) underwent a successful repeated endocardial mapping, and ablation after epicardial mapping yielded no early activation site. Epicardial mapping was helpful in guiding endocardial ablation in 2 patients (9.5%), showing that the earliest activation was simultaneous at the epicardium and endocardium. Four patients (19%) underwent successful open-chest surgery after failing epicardial/endocardial ablation. Two patients (9.5%) remained controlled under antiarrhythmic drugs after unsuccessful endocardial/epicardial ablation. Two patients had a coronary sinus diverticulum and one a right atrium to right ventricle diverticulum. Three patients acquired postablation coronary sinus stenosis. There was no major complication related to pericardial access. Conclusions-Percutaneous epicardial approach is an alternative when conventional endocardial or transvenous epicardial ablation fails in the elimination of the accessory pathway. A new attempt by endocardial approach was successful in a significant number of patients. Open-chest surgery may be required in symptomatic cases refractory to endocardial-epicardial approach.

conferenceObject Transseptal puncture using electroanatomical mapping: a safe and cost-effective technique(2023) BRIGIDO, A. Dantas; RASSI, G. M.; RODRIGUES, L. V.; LOVISI, V. B.; PISANI, C. F.; CHOKR, M. O.; HARDY, C. A.; MELO, S. L.; GONCALVES, A. L. M.; MAYRINK, M. P.; KULCHETSCKI, R. M.; SCANAVACCA, M. I.- Epicardial ablation for cardiac arrhythmias: techniques, indications and results(2014) PISANI, Cristiano F.; LARA, Sissy; SCANAVACCA, MauricioPurpose of reviewTo review the most relevant published data on epicardial ablation of cardiac arrhythmias in the last few years.Recent findingsSeveral studies performing epicardial and endocardial ablation have demonstrated that epicardial ablation may improve the results of ventricular tachycardia (VT) ablation in almost all cardiomyopathies. New imaging techniques have been recently applied, refining the identification of patients who actually benefit from epicardial ablation and increasing its safety.SummaryEpicardial VT ablation is an important tool for electrophysiologists to deal with the challenge of scar-related ventricular arrhythmias.
- Bipolar radiofrequency ablation of septal ventricular tachycardia in a patient with dilated cardiomyopathy using two 8-mm tip catheters-case report(2022) FERRAZ, Alberto Pereira; ANDERE, Tamer El; GONCALVES, Andre Luis Martins; CHOKR, Muhieddine Omar; MELO, Sissy Lara; HARDY, Carina; PISANI, Cristiano Faria; SCANAVACCA, Mauricio IbrahimSeptal ventricular tachycardiac exhibit high recurrence rates after radiofrequency ablation, which is mainly attributed to the deep intramyocardial circuits and the inability to create transmural lesions with the conventional unipolar ablation. Bipolar radiofrequency ablation is feasible and it has been reported as a valid technique in these cases, leading to deeper lesion formation, high non-inducibility rates, and acceptable recurrence rates during follow-up. Our goal is to report a successful case of bipolar ablation of a septal ventricular tachycardia using a simple bipolar ablation configuration with two 8-mm tip catheters.
- 2023 HRS expert consensus statement on the management of arrhythmias during pregnancy(2023) JOGLAR, Jose A.; KAPA, Suraj; SAAREL, Elizabeth V.; DUBIN, Anne M.; GORENEK, Bulent; HAMEED, Afshan B.; MELO, Sissy Lara de; LEAL, Miguel A.; MONDESERT, Blandine; PACHECO, Luis D.; ROBINSON, Melissa R.; SARKOZY, Andrea; SILVERSIDES, Candice K.; SPEARS, Danna; SRINIVAS, Sindhu K.; STRASBURGER, Janette F.; TEDROW, Usha B.; WRIGHT, Jennifer M.; ZELOP, Carolyn M.; ZENTNER, DominicaThis international multidisciplinary expert consensus statement is intended to provide comprehensive guidance that can be referenced at the point of care to cardiac electrophysiologists, cardiologists, and other health care professionals, on the management of cardiac arrhythmias in pregnant patients and in fetuses. This document covers general concepts related to arrhythmias, including both brady-and tachyarrhythmias, in both the patient and the fetus during pregnancy. Recommendations are provided for optimal approaches to diagnosis and evaluation of arrhythmias; selection of invasive and noninvasive options for treatment of arrhythmias; and disease-and patient-specific considerations when risk stratifying, diagnosing, and treating arrhythmias in pregnant patients and fetuses. Gaps in knowledge and new directions for future research are also identified.
- Management of massive hemopericardium in the electrophysiology laboratory: The double long sheath technique(2022) CHOKR, Muhieddine Omar; SANTOS, Italo Bruno dos Santos Sousa; GOUVEA, Fabio Cesar; KULCHETSCKI, Rodrigo; ANDERE, Tamer El; HARDY, Carina; PISANI, Cristiano; MELO, Sissy; SCANAVACCA, MauricioAim To describe a simple and useful technique for acute management of massive hemopericardium inside the Electrophysiology (EP) laboratory Methods and results Five patients from a single center experience were identified, all with blood loss above 1000 ml after initial pericardiocenthesis. Using two long 8.5 F transseptal sheaths inside the pericardium space, with continuous negative pressure, allowed the complete cessation of bleeding or hemodynamic maintenance until definitive surgical repair in all patients Conclusion The use of two long sheaths for blood drainage, instead of conventional pericardiocenthesis, might be helpful to manage massive hemopericardium inside EP lab, avoiding urgent cardiac surgery or maintaining clinical stability until surgical staff is available.
