Good morning, in order to check if the PFO is present, I undertook an echocardiogram that gave an ambiguous result.
I followed with other checks by undertaking another colour Doppler echocardiography which resulted in: “basic slight right-to-left microbubbles shunt (<5 microbubbles) that increases in the late stages (moderate level, 5-10 microbubbles). After Valsalva, the shunt is moderate. There is no-aneurysm of the interatrial septum, nor Chiari network. In conclusion: the presence of PFO with basal slight moderate degree shunt and moderate after Valsalva.
Doctors weren’t able to tell me if this characteristic is compatible with diving. I contacted the DAN doctors that told me to follow the recommendations for a Low Bubble diving profile, according to the Swiss Underwater and Hyperbaric Medical Society (SUHMS).
I would like to know how to go on with the investigations to know the potential and real risks. I have been performing recreational diving for 4 years.
