Patent foramen ovale closure by using transesophageal echocardiography for cryptogenic stroke: single center experience in 132 consecutive patients.
Article in Journal of cardiothoracic surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPercutaneous closure of patent foramen ovale (PFO) is routinely performed using plain fluoroscopy in the catheter room. This method results in inevitable radiation damage, adverse effects of contrast agents on kidneys, and high cost. We performed PFO closure with a simplified and economical transesophageal echocardiography (TEE)-only guided approach in the operating room. This study aimed to investigate the feasibility, safety, and effectiveness of the percutaneous closure of PFO by only using TEE.
methodsWe reviewed the medical records of patients who underwent percutaneous PFO closure at our center from December 2013 to December 2017. A total of 132 patients with PFO and cryptogenic strokes underwent PFO closure by using cardi-O-fix PFO device under TEE guidance. The participants comprised 64 and 68 male and female patients, respectively. The mean age and body weight of the patients were 39.40 ± 13.22 years old (12-68 years old) and 65.42 ± 9.70 kg (40-95 kg), respectively. All patients only received aspirin (3-5 mg/kg body weight, oral administration) for 6 months. Contrast-enhanced transthoracic echocardiography (c-TTE) with Valsalva maneuver was performed during follow-up, and questionnaire surveys were obtained at 3, 6, and 12 months after the procedure.
resultsAll (100%) patients were successfully closed. Follow-ups were conducted for 13 months to 48 months, with an average of 27 months. No severe complications were found during the follow-up period. Paroxysmal atrial fibrillation occurred in 4 patients within 3 months after the procedure. No recurrent stroke or death occurred in all patients during the follow-up period. Transient ischemic attack occurred in one patient 6 months after the procedure. Ten (7.6%) patients had a right-to-left shunt, as demonstrated by c-TTE at 12 months of follow-up. Among the 57 patients suffering from migraine, significant relief or resolution was reported by 42 (73.7%) patients.
conclusionTEE-only guided PFO closure was a safe, feasible, and effective method that did not require the use of X-rays and contrast agents.
