Permanent pacemaker implantation following mitral valve surgery. State-of-the-art scoping review.
Article in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis scoping review investigates the prevalence, indications, risk factors, timing and outcomes related to permanent pacemaker implantation following mitral valve surgery.
methodsA comprehensive search of PubMed, Embase and Cochrane databases was conducted to identify studies on permanent pacemaker implantation after mitral valve surgery. Relevant articles discussing prevalence, indications, risk factors, optimal timing, device choice and long-term dependency were included, prioritizing clinical studies and reviews published in the last 2 decades.
resultsThe incidence of permanent pacemaker implantation after isolated mitral valve surgeries varies from 1% to 10%, with observation periods ranging from 2 to 12 days across centres. Atrioventricular block is the most common indication. Risk factors include older age, atrial fibrillation, reduced left ventricular function and prior cardiac surgery. Patients undergoing mitral valve replacement face a higher risk compared to those having mitral valve repair, while minimally invasive surgery and left atriotomy approach are linked to a lower permanent pacemaker rate. Long-term pacemaker dependency ranges between 20% and 60%, with increased rates observed in patients with atrioventricular block or those operated in the setting of infective endocarditis.
conclusionsThis review highlights the complex interplay of factors influencing permanent pacemaker implantation after mitral valve surgery. Future research should focus on strategies to reduce postoperative conduction abnormalities and better identify patients who may require permanent pacemaker during long-term follow-up.
