Usefulness Of Morphology-Voltage-P Wave Duration(MVP) Score As A Predictor Of Atrial Fibrillation Recurrence After Pulmonary Vein Isolation

Objective The goal of the current study was to investigate whether the Morphology-Voltage-P wave duration(MVP)score was a useful scheme in the prediction of rhythm outcome following pulmonary vein isolation(PVI)for patients who have paroxysmal atrial fibrillation(PAF).Methods We retrospectively analyzed baseline demographics,medical history(including preablation age,gender,diabetes mellitus(DM),coronary artery disease(CAD),hypertension,obstructive sleep apnea(OSA),previous stroke or transient ischemic attack(TIA),drug treatment,left atrial(LA)anteroposterior diameter,left ventricular ejection fraction(LVEF),P-wave duration(PWD),interatrial block(IAB)and P-wave amplitude)and rates of atrial fibrillation(AF)recurrence in 12 months after ablation.We also retrospectively evaluate the score’s ability to predict arrhythmia recurrence after PVI procedure for PAF.Results 207 patients(71 females,median age 58.7 years)with symptomatic PAF underwent PVI.From the cohort,32.3%(67)had a recurrence of AF within 1 year.The area of the MVP score under the curve in the receiver operating characteristics(ROC)analysis was0.789(95% CI 0.730-0.840,p < 0.001).The MVP score of 3 more yielded 89.87% specificity and 53.03% sensitivity in predicting unsuccessful cardioversion.Conclusion The results of the present study suggest that the easy-to-measure ECG MVP score can be used to predict recurrence of PAF after PVI.
