Surgical Repair of Posterobasal Ventricular Septal Rupture Complicated by Severe Tricuspid Regurgitation: A Case Report.
Article in Surgical case reports, 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
introductionPosterobasal ventricular septal rupture (P-VSR) developed after acute myocardial infarction (AMI) is often associated with right ventricular infarction and carries a high surgical mortality. The coexistence of tricuspid regurgitation (TR) further aggravates right ventricular dysfunction and right heart failure. Therefore, surgical repair of P-VSR complicated by right ventricular infarction and severe TR is particularly challenging. CASE PRESENTATION: A 75-year-old woman developed acute inferior myocardial infarction complicated by right ventricular infarction. A coronary stent was deployed for right coronary artery occlusion. On day 16 after the onset of AMI, transthoracic echocardiography revealed a P-VSR and severe TR, and she was transferred to our institution for surgical management. Through a right atrial approach, excellent visualization of the P-VSR was obtained. The septal defect was closed securely using two bovine pericardial patches placed on both the right and left ventricular sides of the ventricular septum. Tricuspid valve replacement (TVR) was also performed. Postoperative echocardiography confirmed complete closure of the defect without residual shunt.
conclusionsIn the surgical treatment of P-VSR complicated by severe TR, a right atrial approach may provide adequate exposure of the septal defect while potentially minimizing additional ventricular injury. In selected patients with severe TR in a similar anatomical and clinical context, concomitant TVR may represent a feasible surgical option.
