“…Before anesthesia induction, her APCO was 7.02 L/min, which is equivalent to 140% of the CO of non-pregnant women and the CO of normal parturients [14]. While the ability to increase CO tends to be compromised in Fontan-palliated patients [12], our patient's cardiac function fortunately allowed for CO increase. Meanwhile, her ScvO 2 decreased to 52.2% as a result of a substantial VO 2 increase.…”

“…During the perinatal period, intravascular volume increases and systemic vascular resistance substantially decreases, increasing cardiac output up to 7.0 L/min 12]. For a Fontan-palliated parturient, it is difficult for cardiac output (CO) to be adequately increased, making this type of aggressive volume challenge potentially dangerous for this population [12]. After the induction of spinal-epidural anesthesia, T4 anesthetic level was attained and blood pressure decreased below 100 mm Hg.…”

“…Existen dos conceptos esenciales en la fisiología de un paciente con Fontán: 1) la existencia de un unico ventrículo fisiológico, y 2) entender que todo el retorno venoso sistémico alcanza la circulación arterial pulmonar de forma pasiva, dependiendo de la presión venosa central (PVC), que a su vez está determinada por la resistencia vascular pulmonar (RVP) y la capacitancia del sistema venoso. 1,3 El flujo sanguíneo pulmonar (FSP) es un determinante del gasto cardiaco, ya que la circulación sistémica está en serie con la circulación pulmonar sin intervención del ventrículo derecho. 7 Es así como estos pacientes se caracterizan por tener una PVC aumentada, bajo gasto cardiaco 8 y una ligera disminución en la saturación arterial de oxígeno, para lo que desarrollan adaptaciones como el aumento de las resistencias vasculares arteriales, la redistribución del gasto cardiaco a los órganos vitales y el aumento en la hemoglobina.…”

“…En particular, se ha reemplazado la anastomosis atriopulmonar por una anastomosis cavopulmonar total, que puede realizarse creando un t unel intraauricular o un t unel extracardiaco, a fin de conectar directamente la vena cava inferior con la arteria pulmonar derecha. 3 Esto ha mejorado significativamente el pronóstico y la sobrevida de los pacientes, haciendo que presenten menos arritmias y probablemente pospongan la aparición de falla cardiaca, 5,6 lo que permite que individuos con lesiones cardiacas congénitas lleguen a una vida adulta y se presenten cada vez con mayor frecuencia en el entorno perioperatorio para procedimientos no cardiacos. 1…”

“…The second series included patients with evidence of “failing Fontan” (poor functional status, worsening cyanosis, atrial arrhythmias, cirrhosis, and protein‐losing enteropathy), but is unclear which procedures had been performed and which anesthetic techniques were used. There is no doubt GA confers a higher risk for this subgroup of patients, and good perioperative management requires thorough knowledge of Fontan physiology …”
