Minimally invasive LVAD implantation for advanced heart failure: a single-center retrospective analysis and the promise of minimally invasive approaches.
Article in Journal of cardiothoracic 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
objectiveThis study aimed to preliminarily investigate the feasibility, safety, and early clinical outcomes of minimally invasive left ventricular assist device (LVAD) implantation with concomitant cardiac procedures.
methodsWe retrospectively analyzed the clinical data of three consecutive male patients with end-stage heart failure who underwent minimally invasive LVAD implantation at our center between August and November 2024. Two patients received the CorHeart 6 LVAD, while one received the CH-VAD LVAD. Two patients underwent concomitant procedures (patent foramen ovale closure or left atrial appendage occlusion) during the LVAD implantation.
resultsAll procedures were successfully completed without intraoperative mortality or conversion to sternotomy. Cardiopulmonary bypass time ranged from 121 to 214 min. Postoperative echocardiography demonstrated reduced ventricular dimensions, improved ejection fraction, and resolution of significant valvular regurgitation in all patients. The duration of mechanical ventilation ranged from 1 to 5 days, and the ICU stay ranged from 3 to 7 days. No mortality, pump thrombosis, stroke, or reoperation for bleeding occurred. One patient experienced transient postoperative arrhythmia, which resolved with medical management.
conclusionThis initial experience suggests that minimally invasive LVAD implantation via left thoracotomy, with concomitant cardiac procedures, is technically feasible and safe in selected patients with end-stage heart failure. This strategy was associated with encouraging early outcomes and provides early clinical data on the minimally invasive application of devices such as the CorHeart 6 to the international LVAD community.
