RESUMO
Resumen Paciente de 48 años con historia de fibrilación auricular paroxística, dislipidemia y antecedente de ablación de vía accesoria (2013). Anti coagulado con Rivaroxaban 20 mg PO. Paciente es llevado a aislamiento percutáneo de venas pulmonares (AVP) con sistema de navegación tridimensional Carto 3. 48 horas post AVP inicia con cuadro de distrés respiratorio agudo que requiere hospitalización en unidad de cuido intensivo, que resuelve con manejo diurético y antiinflamatorio. Describimos la importancia del manejo hídrico en relación al AVP.
Abstract 48 years old male, previous history of paroxysmal atrial fibrillation, hiperlipemia and previous accesory pathway ablation an 2013. Anticoagulated with Rivaroxaban 20mg PO. Patient underwent pulmonary vein insolation (PVI) with Carto 3 tridimensional navigation and mapping system. Discharged on day 1 after PVI, readmitted with acute respiratory distress that required intensive care unit admission that resolves with diuretics and anti-inflammatory management. We describe the role of hydric management related with PVI procedure.

BACKGROUND: The occurrence of periprocedural acute hemodynamic decompensation (AHD) in patients undergoing radiofrequency catheter ablation of scar-related ventricular tachycardia (VT) has not been previously investigated. METHODS AND RESULTS: We identified univariate predictors of periprocedural AHD in 193 consecutive patients undergoing radiofrequency catheter ablation of scar-related VT. AHD was defined as persistent hypotension despite vasopressors and requiring mechanical support or procedure discontinuation. AHD occurred in 22 (11%) patients. Compared with the rest of the population, patients with AHD were older (68.5±10.7 versus 61.6±15.0 years; P=0.037); had a higher prevalence of diabetes mellitus (36% versus 18%; P=0.045), ischemic cardiomyopathy (86% versus 52%; P=0.002), chronic obstructive pulmonary disease (41% versus 13%; P=0.001), and VT storm (77% versus 43%; P=0.002); had more severe heart failure (New York Heart Association class III/IV: 55% versus 15%, P<0.001; left ventricular ejection fraction: 26±10% versus 36±16%, P=0.003); and more often received periprocedural general anesthesia (59% versus 29%; P=0.004). At 21±7 months follow-up, the mortality rate was higher in the AHD group compared with the rest of the population (50% versus 11%, log-rank P<0.001). CONCLUSIONS: AHD occurs in 11% of patients undergoing radiofrequency catheter ablation of scar-related VT and is associated with increased risk of mortality over follow-up. AHD may be predicted by clinical factors, including advanced age, ischemic cardiomyopathy, more severe heart failure status (New York Heart Association class III/IV, lower ejection fraction), associated comorbidities (diabetes mellitus and chronic obstructive pulmonary disease), presentation with VT storm, and use of general anesthesia.
