A patent foramen ovale (PFO), or a \u201chole in the heart,\u201d is a known risk factor for decompression sickness (DCS). This study sought to determine if closing this hole in a surgical procedure would decrease the risk of DCS and compared these findings to divers that were advised to dive more conservative profiles. Results corroborated current guidelines outside of the standardized research environment.<\/em><\/p>\n\n\n\n

El foramen oval permeable (FOP), un defecto card\u00edaco cong\u00e9nito frecuente, es un orificio entre los lados derecho e izquierdo del coraz\u00f3n. Durante casi 40 a\u00f1os, se ha sospechado que las burbujas de gas inerte pueden viajar a trav\u00e9s de este orificio y causar la enfermedad por descompresi\u00f3n (EDC).<\/p>\n\n\n\n

In the beginning, there were two options for scuba divers with PFOs seeking to reduce their DCS risk: to stop diving or to dive more conservatively, such as conducting shallower profiles or diving nitrox on air tables. Recently, interventional cardiologists have begun to offer PFO closure as a third DCS risk mitigation strategy. Scientists have shown this procedure to be effective in reducing DCS risk in hyperbaric chamber studies and in standardized research environments, but its efficiency in the \u201creal world\u201d has not yet been established. Divers with PFOs needed to know how effective PFO closure was in reducing DCS risk outside of a highly regulated hospital. The goal of the DAN PFO study was to determine this information.<\/p>\n\n\n\n

El estudio realiz\u00f3 un seguimiento de 23 buceadores con FOP que practicaron el buceo de forma conservadora y de 42 buceadores con FOP que se sometieron a un cierre del FOP durante un periodo de hasta seis a\u00f1os. Se examin\u00f3 si la decisi\u00f3n de bucear de forma conservadora o de cerrar el FOP reduc\u00eda la incidencia de DCS.<\/p>\n\n\n\n

Results showed that PFO closure reduced the incidence of DCS. Conservative diving\u2019s effect was inconclusive, most likely due to a small sample size. Since surgical procedures are not without risk, a subset of divers was identified that would benefit most and should consider this procedure. These were healthy divers with large PFOs, previous histories of serious DCS and strong desires to pursue advanced diving.<\/p>\n\n\n\n
