Abstract
Radiofrequency catheter ablation (CA) has an established role in the management of patients with structural heart disease presenting with recurrent ventricular tachycardia (VT). Due to the complex underlying substrate, high burden of comorbidities and concomitant heart failure (HF) status, these patients may be at higher risk of periprocedural complications. The prolonged low-output state related to VT induction and mapping, as well as the fluid overload due to irrigated CA and the use of general anaesthesia, may decompensate the HF status, leading to multiple-organ failure and increase in early post-procedural mortality. Proper identification of patients at high risk of periprocedural acute haemodynamic decompensation (AHD) has important implications in terms of procedural planning (i.e. prophylactic use of mechanical assistance devices) and pre-procedural management in order to optimise the HF status. In the present manuscript we focus on the clinical predictors of AHD and the strategies to improve pre-procedural risk stratification, as well as the evidence supporting the use of haemodynamic support during CA procedures.
