Echocardiographic Assessment After Heart Transplant.
Review in Diagnostics (Basel, Switzerland), 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
Heart transplantation remains the gold-standard therapy for selected patients with end-stage heart failure, yet acute rejection and cardiac allograft vasculopathy (CAV) continue to limit long-term survival. While endomyocardial biopsy and coronary angiography remain the reference standards for diagnosing rejection and CAV, respectively, echocardiography offers a non-invasive, repeatable tool for the longitudinal surveillance of heart transplant recipients. This review summarizes the expected echocardiographic findings following orthotopic heart transplantation according to surgical technique (biatrial versus bicaval) and describes the echocardiographic features of early graft dysfunction, acute allograft rejection, and late graft failure due to cardiac allograft vasculopathy. We also discuss the incremental value of newer echocardiographic techniques-including speckle-tracking-derived strain, myocardial work, and three-dimensional echocardiography-in detecting subclinical left ventricular and right ventricular dysfunction that may precede changes detectable by conventional parameters. No single echocardiographic parameter reliably diagnoses rejection or vasculopathy in isolation; an integrated, multiparametric approach combined with clinical data is required. Emerging techniques hold promise for reducing reliance on invasive surveillance, although further validation in larger, multicenter cohorts is needed. This review aims to provide echocardiographers and transplant cardiologists with a practical, imaging-based framework for the follow-up of heart transplant recipients across the early postoperative period and long-term surveillance.
