Left ventricular assist devices and right heart dysfunction: a review of impact mechanisms, evaluation methods, and prevention and management.
Review in Journal of cardiothoracic surgery, 2026. 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
backgroundLeft ventricular assist devices (LVADs) have become an important treatment option for patients with end-stage heart failure, significantly improving left ventricular function and patient survival rates. However, LVAD implantation has complex effects on right heart function, and right heart dysfunction is a critical factor affecting patient prognosis and quality of life.
methodsThis article systematically reviews the relationship between LVADs and right heart function, focusing on the importance of right heart function in LVAD patients, evaluation methods, impact mechanisms, and prevention and management strategies. Additionally, it introduces emerging technologies and future research directions to provide references for clinical practice.
resultsStudies have shown that comprehensive evaluation of right heart function is crucial for predicting the risk of postoperative right heart dysfunction. The impact mechanisms of LVAD implantation on right heart function are complex, including changes in preload and afterload and ventricular interdependence. Prevention and management of right heart dysfunction require comprehensive measures, including preoperative optimization, meticulous intraoperative procedures, close postoperative monitoring, and multidisciplinary team collaboration. Emerging technologies such as improved LVAD designs, biventricular assist devices, gene therapy, and personalized medicine offer new hope for reducing the incidence of right heart dysfunction.
conclusionRight heart function holds undeniable importance in LVAD therapy. Through comprehensive evaluation, prevention, and management of right heart function, as well as the application of new technologies, it is expected to reduce the incidence of right heart dysfunction and improve the prognosis and quality of life of LVAD patients. More high-quality research is needed in the future to promote the clinical application of emerging technologies and provide more comprehensive treatment options for patients with end-stage heart failure.
