WebObjectives: A few studies have described the outcomes of systemic-to-pulmonary artery shunt (SPS) for functional single ventricular heart with extracardiac total anomalous pulmonary venous connection (TAPVC). This study aimed to examine the outcomes of SPS with extracardiac TAPVC and identify the predictors of mortality before bidirectional … WebRight-to-left pulmonary and cardiac shunts (RLS) are important causes of refractory hypoxia in the critically-ill perioperative patient. Using a point-of-care ultrasound (POCUS) agitated saline bubble study for an early diagnosis allows patients with clinically significant RLSs to receive expedited therapy.
Webshunt studies are shown to the left of closed shunt studies in spite of the lowering of PAP during shunt closure, groups are arranged relative to increasing mean pulmonary artery pressures, i.e., CONT02S had the lowest pressure, and MCTPras had the highest pressures. With the exception of CONT02S, all groups displayed WebPulmonary shunt. We defined pulmonary shunts as cases with visible microbubbles drained from the right or left pulmonary veins on TOE. Because many cases with pulmonary …
