The perfect prosthesis/patient match: pursuit of the Holy Grail.
Review in Annals of cardiothoracic surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
In 1978, Rahimtoola published a successful series of surgical aortic valve replacements (SAVR) on patients with severe aortic stenosis (AS) with congestive heart failure (CHF). He described the perfect prosthesis-patient match as a "prosthetic valve with a functioning opening area that matches the patient's normal functioning valve." This manuscript revisits the forty-six-year journey in pursuit of that perfect match. We address the essential components for the perfect match, such as the usefulness of the current valve sizing techniques using the manufacturer's labeled valve size (MLVS) and sizer, the accuracy of an objective parameter to define the perfect match, and the need and safety to enlarge the patient's annulus and root to accommodate the proper size valve. A thorough literature search was performed using the University of Michigan Medical Library search engine. The population included patients who underwent SAVR. Three individual searches were conducted: (I) valve size and sizing techniques; (II) hemodynamic performance (HP) and prosthesis-patient mismatch (PPM); and (III) aortic root enlargement (ARE) procedures. Excluded were articles not in English, articles that involved animal research, duplicate articles, articles involving valve repair, allograft or autograft replacement, and articles specific to aortic sizing and congenital heart surgery. The emphasis was placed on randomized prospective trials, large registry trials with and without propensity matching, and meta-analysis articles. We discovered that the manufacturer-labeled valve size and sizing technique does not accurately represent the functional opening area of the valve. A pre-operative multidetector computed tomography (CT) scan is an accurate and reproducible method for measuring patient root and annulus dimensions and should be used for pre-operative valve sizing for SAVR. Matching the CT area derived aortic diameter with the true functional diameter of the opening of the prosthetic valve will yield the best prosthesis-patient match. ARE is safe and should be used to attain the best match.
