Changes in echocardiographic parameters of the donor's heart before and after heart transplantation and their relationship with post-transplant survival.

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
Background: Heart transplantation is now widely performed in China, but the current entry criteria for heart transplantation donors are simple and lack reliable standards; there are still no studies on the effect of preoperative echocardiographic parameters of heart transplantation donors on the prognosis of the recipient. Therefore, the aim of this study is twofold: (I) to observe the characteristics of changes in echocardiographic parameters of the donor's heart before and after heart transplantation and (II) to study the relationship between the changes in echocardiographic parameters of the donor's heart pre- and post-transplant and transplant recipient survival. Methods: A total of 29 patients who underwent orthotopic heart transplant in our hospital from October 2016 to October 2019 were enrolled in this study. All recipients were followed up until April 2020. Echocardiographic data were collected pre-transplantation (donor) and at 1 week and 1 month post-transplant (recipient). Results: Compared with the pretransplanted donor's heart, there was an increase in the interventricular septal diameter, left ventricular posterior wall diameter, right atrium diameter and right ventricular diameter, while a decrease was found in the tricuspid annular systolic displacement and tricuspid annular peak systolic velocity at 1 week post-transplant. The survival curve showed that the postoperative survival time in the right atrium/ventricle ≥32 mm group was better than that in the right atrium/ventricle <32 mm group. The survival curve also showed that the postoperative survival time in the right atrium/ventricle enlargement <2 mm group was better than that in the right atrium/ventricle enlargement ≥2 mm group. Conclusions: In the early post-transplant period, ventricular myocardial thickening, right heart enlargement and a decrease in right heart function were observed in the post-transplanted heart compared to the pretransplanted donor's heart. Postoperative survival was higher among heart transplant patients who received a heart with right atrium/ventricle ≥32 mm. Postoperative survival was lower among heart transplant patients whose right atrium/ventricle was dilated ≥2 mm at 1 month postoperatively compared with the pretransplanted donor's heart.
