Previous studies have shown that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) could reverse structural and electrical atria remodelling and decrease atrial fibrillation (AF) onset or recurrence. The aim of this retrospective study was to investigate whether ACEIs/ARBs had beneficial effects on ablation outcome of chronic persistent AF. ⋯ In this observational study, no effect of ACEIs or ARBs was seen on the AF recurrence after ablation of chronic persistent AF.ACEIs/ARBs did not help to predict a better ablation outcome. Predictors for ablation outcome are AF history and duration of chronic persistent AF.

Case Reports
Paroxysmal bidirectional ventricular tachycardia with tachycardiomyopathy in a pregnant woman.
Palpitations in pregnancy are not an uncommon complaint. We present a case of palpitations in the third trimester related to bidirectional ventricular tachycardia with evidence, of left ventricular systolic dysfunction. The case was successfully managed with flecainide therapy and urgent elective caesarean section. ⋯ A literature review of bidirectional ventricular tachycardia is presented. This is the first reported case of bidirectional VT producing LV systolic dysfunction, which normalised following stabilisation of rhythm. The complex issues of management of this case in particular with regard to the pregnancy are discussed.
