Abstract:
Objective:To comparatively analyze the diagnostic value of patent foramen ovale and the degree of right-to-left shunt among the traditional Valsalva maneuver (VM), the modified Valsalva maneuver (mVM) and the compression of the inferior vena cava combined with modified Valsalva maneuver (CM).Methods:A total of 132 patients with migraine, dizziness, chest pain and other symptoms in Longgang District People′s Hospital of Shenzhen from January 2021 to December 2021 were prospectively enrolled. The detection rate of patent foramen ovale and the degree of right-to-left shunt were assessed among the rest state and after performing the auxiliary maneuvers including VM, mVM and CM respectively.Results:After performing the auxiliary maneuvers, the detection rate of patent foramen ovale was significantly increased (88.6% vs 59.8%) with statistical significance (χ 2=36.026, P<0.001). There was a significant difference in the degree of right-to-left shunt among the three auxiliary maneuvers (χ 2=25.581, P<0.001). CM was the most effective for the detection of the large right-to-left shunt, and the difference was statistically significant compared with VM and mVM ( P<0.001, P=0.002). Conclusions:Auxiliary maneuvers is crucial for the diagnosis of patent foramen ovale. Compared with VM and mVM, performing CM can further improve the detection rate of patent foramen ovale and increase the degree of right-to-left shunt.
