The predictive value of echocardiographic parameters associated with left ventricular diastolic dysfunction on short- and long-term outcomes of catheter ablation of atrial fibrillation

Abstract

Early results of the catheter ablation, but not the late rhythm outcome, are influenced by an impaired mitral inflow pattern, which is associated with LVDD.

EHRA/HRS/APHRS/SOLAECE expert consensus on atrial cardiomyopathies: definition, characterization, and clinical implication

“…However, late recurrences are common and associated with more advanced atrial substrate associated with structural heart disease. [436][437][438][439][440][441][442][443][444][445][446] It is in this context that it is important to consider the various types of underlying atrial cardiomyopathy and how they may affect ablation outcomes. This is timely, as it has recently been observed that lone AF is a rapidly disappearing entity as we recognize conditions such as sleep apnoea, obesity, endurance exercise etc.…”

Echocardiographic predictors of atrial fibrillation recurrence after catheter ablation: A literature review

“…Kosiuk et al [27] showed that E/A mitral inflow pattern (early to late mitral inflow velocity ratio, assessed by pulsed-wave Doppler at the level of the mitral valve), which is associated with LV diastolic dysfunction, was the best pre-procedural predictor of short-term AF recurrence during the first week after PVI. An E/A ratio of 1.35 was the cut-off value with the highest sensitivity and specificity for predicting early AF recurrence.…”

“…This discrepancy may be due to different definitions of LV diastolic dysfunction applied in both studies. Moreover, Kosiuk et al [27] analyzed the results of CA after only a single procedure, and it can also explain the contradictory results because, as mentioned above, late AF recurrences are mainly due to pulmonary vein reconnections [28,29]. Finally, a limited number of patients with severe LV diastolic dysfunction might preclude evaluation of other parameters, like E/e' ratio as predictors of both, short-and longterm AF recurrences after CA.…”
