Marrouche 2007.
Methods | Randomised controlled trial | |
Participants | 53 Symptomatic AF patients who were followed up for 3 months. 27 patients were assigned to PVAI using the MB monitoring approach, and 26 were using the irrigated tip catheter. Paroxysmal AF accounted for 61.5% and 63% in both group respectively. Age: 53+/‐8 years in OIT catheter group, and 54+/‐8 years in ICE guidance group. % of male: 19/26 (73%) in OIT catheter group, and 21/27 (78%) in ICE guidance group. Follow‐up: three months for paroxysmal AF patients, and six months for persistent AF patients. Location: Salt Lake City, Utah, USA. |

Interventions | Group 1: Open irrigation ablation technology for PV isolation. Group 2: Pulmonary vein antrum isolation under ICE guidance. |
|
Outcomes | Sinus rhythm restored, complications | |
Notes | PVAI: pulmonary vein‐atrium isolation. | |
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Insufficient detail was provided. |
Allocation concealment (selection bias) | Unclear risk | B‐Unclear. The authors did not depict allocation concealment method. |
Blinding | High risk | Blinding was not reported. |
Incomplete outcome data addressed | High risk | There were no patients withdrawn or lost to follow up. |
Adequate sequence generation | Unclear risk | It was not addressed. |
