Exercise testing may reveal pulmonary hypertension missed at rest in post-ablation vein stenosis; leaves open whether intervention alters outcomes.
Does significant pulmonary vein stenosis after radiofrequency catheter ablation for atrial fibrillation cause pulmonary hypertension at rest or during exercise?
Significant pulmonary vein stenosis or occlusion after atrial fibrillation ablation does not cause resting pulmonary hypertension but frequently leads to exercise-induced pulmonary hypertension.
Arentz et al. (2005) studied this question.
