    IT WAS REPORTED THROUGH THE RESEARCH ARTICLE ¿SAFETY AND HEMODYNAMIC IMPLICATIONS OF TRANSSEPTAL ACCESS FOR VENTRICULAR TACHYCARDIA ABLATION IN PATIENTS WITH LEFT VENTRICULAR ASSIST DEVICES¿ THAT THE HEARTMATE 3 (HM3) MAY BE ASSOCIATED WITH VENTRICULAR TACHYCARDIA, VENTRICULAR ANEURYSM, PULMONARY HYPERTENSION, MODERATE OR SEVERE RIGHT VENTRICLE DYSFUNCTION, TRANSPLANTATION, AND DEATH. A TOTAL OF 15 PATIENTS WITH LVAD UNDERWENT 19 VENTRICULAR TACHYCARDIA ABLATION PROCEDURES WITH SINGLE TRANSSEPTAL ACCESS FOR LEFT VENTRICLE (LV) ABLATION WITHOUT ATRIAL SEPTAL DEFECT (ASD) CLOSURE. LVADS INCLUDED HEARTMATE 3 AND HEARTWARE HVAD. 6 HAD PULMONARY HYPERTENSION, AND 7 HAD MODERATE OR SEVERE RIGHT VENTRICLE DYSFUNCTION. POST-PROCEDURE ECHOCARDIOGRAMS (N = 14; MEDIAN TIME TO ECHO 57 DAYS) SHOWED NO INTRACARDIAC SHUNTING OR PERSISTENT ASD. RIGHT HEART CATHETERIZATION (RHC) (PRE: N = 14; POST: N = 8, AT MEDIAN FOLLOW-UP 92.5 DAYS) SHOWED SIMILAR PRE-AND POST-ABLATION RA PRESSURES (11.5 VS. 12 MMHG, P = 0.17) AND WEDGE PRESSURES (20.5 VS. 19.5 MMHG, P = 0.99). SIGNIFICANT SHUNTING WAS ABSENT ON PRE- VERSUS POST-ABLATION ARTERIAL (MEDIAN 95% VS. 99%) AND PA OXYGEN SATURATIONS (58% VS. 62%). NO CLINICALLY SIGNIFICANT RIGHT-LEFT SHUNTING OR HYPOXIA/HYPOXEMIA OCCURRED POST-ABLATION. OVER MEAN FOLLOW-UP OF 581 ± 418 DAYS AFTER LAST ABLATION, 10 PATIENTS REMAINED ALIVE, 1 OF WHOM UNDERWENT HEART TRANSPLANTATION. 5 PATIENTS DIED DURING FOLLOW-UP (4 FROM CONDITIONS UNRELATED TO ABLATION AND 1 FROM RECURRENT VT). AT 1 YEAR AFTER LAST ABLATION, VA RECURRED IN 5 (30%) PATIENTS (FIG. 1A).
