Aortic Valve-Sparing Repair of a Giant Left Ventricular Outflow Tract Pseudoaneurysm With Severe Aortic Regurgitation.

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
backgroundLeft ventricular outflow tract (LVOT) pseudoaneurysms are rare but life-threatening entities arising from various etiologies, including infections, inflammation, and iatrogenic trauma. CASE SUMMARY: A 39-year-old man presented with pleuritic chest pain, fever, and cough. He was initially treated for pneumonia but was later found to have a giant LVOT pseudoaneurysm on multimodality imaging. Infectious and inflammatory causes were ruled out. Surgical repair was successfully performed using a valve-sparing approach with a bovine pericardial patch. Postoperatively, the patient had a favorable outcome with preserved aortic valve function. DISCUSSION: This case highlights the diagnostic challenges and surgical strategy of valve preservation in LVOT pseudoaneurysm management. TAKE-HOME MESSAGES: Rapid multimodal imaging and urgent surgical intervention are imperative to avert potentially fatal rupture of LVOT pseudoaneurysms. Valve-sparing repair techniques, even in anatomically complex pseudoaneurysms, can reliably preserve native valve function when performed at high expertise centers.
