    RELATED MANUFACTURE REF: 3008452825-2024-00069. THE FOLLOWING WAS PUBLISHED IN THE HEART RHYTHM 20.12: 1708-1717. ELSEVIER B.V. (DEC 2023) IN AN ARTICLE TITLED "CRYOTHERMAL ENERGY DEMONSTRATES SHORTER ABLATION TIME AND LOWER COMPLICATION RATES COMPARED WITH RADIOFREQUENCY IN SURGICAL HYBRID ABLATION FOR RECURRENT VENTRICULAR TACHYCARDIA"; BRADFIELD, JASON S; HTTP://DX.DOI.ORG/10.1016/J.HRTHM.2023.08.036. BETWEEN 2009 AND 2022, 43 PATIENTS UNDERWENT EITHER A CRYOTHERMAL (N 5 17) OR A RADIOFREQUENCY (N 5 26) HYBRID EPICARDIAL ABLATION PROCEDURE WITH DIRECT SURGICAL ACCESS. BOTH GROUPS WERE SIMILARLY MATCHED FOR AGE, SEX, ETIOLOGY OF VT, AND COMORBIDITIES WITH A HIGH BURDEN OF REFRACTORY VT DESPITE PREVIOUS ENDOCARDIAL AND/OR PERCUTANEOUS EPICARDIAL ABLATION PROCEDURES. THE SURGICAL ACCESS SITE WAS LATERAL THORACOTOMY (76.5%) IN THE CRYOTHERMAL ABLATION GROUP COMPARED WITH LATERAL THORACOTOMY (42.3%) AND SUBXIPHOID APPROACH (38.5%) IN THE RADIOFREQUENCY GROUP, WITH THE REMAINDER IN BOTH GROUPS PERFORMED VIA MEDIAN STERNOTOMY. THE ABLATION TIME WAS SIGNIFICANTLY SHORTER IN THOSE UNDERGOING CRYOTHERMAL ABLATION VS RADIOFREQUENCY ABLATION (11.54 6 15.5 MINUTES VS 48.48 6 23.6 MINUTES; P,.001). THERE WERE NO COMPLICATIONS IN THE CRYOTHERMAL ABLATION GROUP COMPARED WITH 6 PATIENTS WITH COMPLICATIONS IN THE RADIOFREQUENCY GROUP. RECURRENT VT EPISODES AND ALL-CAUSE MORTALITY WERE SIMILAR IN BOTH GROUPS. COMPLICATIONS PRIMARILY COMPRISED BLEEDING AND ALL OCCURRED IN LATERAL THORACOTOMY ACCESS. TWO PATIENTS WITH PERICARDIAL HEMORRHAGE REQUIRING BLOOD TRANSFUSION, ONE PATIENT WITH A STERNAL INCISIONAL HEMATOMA REQUIRING EVACUATION AND ONE PATIENT EXPERIENCED A PERICARDIAL EFFUSION WHICH REQUIRED SURGICAL REOPENING. ONE PATIENT HAD A PERICARDIAL HEMORRHAGE RESULTING IN DEATH THE FOLLOWING DAY.
