Transesophageal Echocardiography-Related Complications During Mitral Valve Repair in Dogs.
Article in Journal of veterinary internal medicine. 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
backgroundTransesophageal echocardiography (TEE) is an indispensable modality in cardiac surgery; however, the complications associated with its use in veterinary clinical settings remain unclear. HYPOTHESIS/
objectivesTo investigate the complications associated with TEE probe manipulation during mitral valve repair in dogs and identify the risk factors for new mucosal injuries. ANIMALS: This prospective study evaluated 60 client-owned dogs that underwent TEE to support mitral valve repair.
methodsEsophageal endoscopy was performed twice-once after anesthesia induction and once before extubation-to assess esophageal mucosal injuries during the procedure. The type of injury was classified as 'complex' (intramural hematoma and mucosal laceration), 'minor' (petechiae and ecchymosis), or 'minute' (visible only on narrowband imaging) lesions. During the surgery, TEE was performed three times. Hemodynamics were evaluated before the initial TEE insertion and immediately after it was removed.
resultsOf the 60 dogs, newly detected mucosal lesions were observed in 20 dogs and classified as 'minor' in four and 'minute' in 16 dogs. These 'minute' lesions were not visible with conventional endoscopy, and no 'complex' lesions were identified. No significant factors were associated with the presence of mucosal lesions. After TEE insertion, systolic blood pressure decreased from 95 ± 13 mmHg to 92 ± 11 mmHg (p = 0.008), and heart rate decreased from 128 ± 25 bpm to 123 ± 24 bpm (p < 0.001). CONCLUSIONS AND CLINICAL IMPORTANCE: Intraoperative TEE results in a low incidence of esophageal mucosal injuries. Hemodynamic changes could occur during TEE manipulation, underscoring the need for close monitoring.
