Effectiveness of transthoracic echocardiogram in patent foramen ovale diagnosis. Systematic review of last ten years

Mostrar todas las versiones(2)

Background: Transesophageal echo (TEE) bubble study is the current gold standard for patent foramen ovale (PFO) diagnosis, but it has the disadvantage of being semi-invasive and not exempted from risks. The aim of this study was to determine the accuracy of TTE compared to TEE for PFO diagnosis. Met...

Sumario:Background: Transesophageal echo (TEE) bubble study is the current gold standard for patent foramen ovale (PFO) diagnosis, but it has the disadvantage of being semi-invasive and not exempted from risks. The aim of this study was to determine the accuracy of TTE compared to TEE for PFO diagnosis. Methods and results: a systematic review was done on Medline with the terms "transthoracic echocardiography, transesophageal echocardiography, patent foramen ovale, diagnosis" yielding published literature of the last ten years. The search was completed in february 2018. Of 715 articles, 10 were analyzed. The total of patients were 1268 (mean age of 47 years +/-14) with a global prevalence of PFO of 48%. The sensibility of ETT was 90 % (IC 95: 88 % - 92 %) and the specificity 92% (IC 95: 89 % - 94 %). The positive predictive value was 93% (IC 95: 90 % - 94 %) and the negative predictive value 89 % (IC 95: 87 % - 91 %). The area under the curve and Q index value were 0,97 and 0,93 respectively. The positive and negative likelihood ratio were 18,989 and 0,072 respectively. Conclusion: The ETT shows a good specificity and sensibility for PFO diagnosis with last generation equipments, contrast use and valsalva maneuver; according to the analyzed studies.
