Outcome after left ventricular assist device exchange.
Article in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesLeft ventricular assist device (LVAD) therapy has evolved from a short-term bridge-to-transplant strategy into a long-term and often chronic therapy due to long waiting times for heart transplantation and application as destination therapy. Consequently, patients are at risk of developing complications necessitating LVAD exchange. The aim of this study is to assess patient outcomes after LVAD exchange.
methodsPatients who underwent LVAD exchange between January 2010 and December 2022 were included. Logistic and cox regression analyses were used to identify potential risk factors for short and long-term adverse events, respectively. Survival after exchange was assessed using Kaplan-Meier estimates.
resultsSixty-one patients underwent a total of 80 LVAD exchanges. Most frequently observed short-term complications were pulmonary infections (16.3%) and right heart failure (16.3%). Exit-site infections (34.7%) and device malfunctions (25.3%) were the most often observed long-term complications. HeartWare ventricular assist device as index device was associated with a higher risk of right heart failure [hazard ratio 6.42, 95% confidence interval (CI) 1.80-22.90] and respiratory failure (hazard ratio 7.81, 95% CI 1.95-31.23) compared to HeartMate II and HeartMate 3. Survival was 83% (95% CI 75.5-95.3%) at 1 year and 67% (95% CI 53.9-84.7%) at 6 years after exchange. After 5 years, 25.0% was transplanted, 23.8% had undergone a re-exchange and 32.5% was alive without new intervention.
conclusionsAlthough LVAD exchange can be performed with a relatively low mortality, other post-operative adverse events are common. Patients with the HeartWare ventricular assist device as index device may be at higher risk of developing right heart failure and respiratory failure after exchange.
