Background For patients with hypoplastic left heart syndrome, digoxin has been associated with reduced interstage mortality after the Norwood operation, but the mechanism of this benefit remains unclear. Preservation of right ventricular (RV) echocardiographic indices has been associated with better outcomes in hypoplastic left heart syndrome. Therefore, we sought to determine whether digoxin use is associated with preservation of the RV indices in the interstage period. Methods and Results We conducted a retrospective cohort study of prospectively collected data using the public use data set from the Pediatric Heart Network Single Ventricle Reconstruction trial, conducted in 15 North American centers between 2005 and 2008. We included all patients who survived the interstage period and had echocardiographic data post‐Norwood and pre‐Glenn operations. We used multivariable linear regression to compare changes in RV parameters, adjusting for relevant covariates. Of 289 patients, 94 received digoxin at discharge post‐Norwood. There were no significant differences in baseline clinical characteristics or post‐Norwood echocardiographic RV indices (RV end‐diastolic volume indexed, RV end‐systolic volume indexed, ejection fraction) in the digoxin versus no‐digoxin groups. At the end of the interstage period and after adjustment for relevant covariates, patients on digoxin had better preserved RV indices compared with those not on digoxin for the ΔRV end‐diastolic volume (11 versus 15 mL, P =0.026) and the ΔRV end‐systolic volume (6 versus 9 mL, P =0.009) with the indexed ΔRV end‐systolic volume (11 versus 20 mL/BSA 1.3 , P =0.034). The change in the RV ejection fraction during the interstage period between the 2 groups did not meet statistical significance (−2 versus −5, P =0.056); however, the trend continued to be favorable for the digoxin group. Conclusions Digoxin use during the interstage period is associated with better preservation of the RV volume and tricuspid valve measurements leading to less adverse remodeling of the single ventricle. These findings suggest a possible mechanism of action explaining digoxin’s survival benefit during the interstage period.

Hypoplastic left heart syndrome (HLHS) and single ventricle (SV) remain a significant cause of cardiac deaths occurring in the first week of life. Their pathogenesis and seasonal frequency are still unknown. Therefore, we attempt to look at the genesis of the HLHS and SV in the context of territorial distribution as well as seasonality. A total of 193 fetuses diagnosed with HLHS and 92 with SV were selected. The frequency was analyzed depending on the year, calendar month, quarter and season (fall-winter vs. spring-summer). The spatial distribution of HLHS and SV in Poland was analyzed. We observed a statistically significant overrepresentation of HLHS formation frequency in March: 27 (14.00%) in comparison to a monthly median of 15 (IQR: 13.75–16.25; p = 0.039), as well as a significantly higher frequency of HLHS in 2007−2009: 65 cases (33.68%) in comparison to the annual mean of 13.79 ± 6.36 (p < 0.001). We noted a higher frequency of SV among parous with the last menstrual period reported in the fall/winter season of 58 vs. 34 in the spring/summer season (p = 0.014). The performed analysis also revealed significant SV overrepresentation in 2008: 11 cases (12.00%) in comparison to the annual mean of 6.57 ± 2.71 (p = 0.016). Every single case of HLHS was observed when the concentration of benzo(a)pyrene and/or PM10 exceeded the acceptable/target level. Our research indicates that both the season and the level of pollution are significant factors affecting the health of parous women and their offspring. The reason why HLHS and SV develop more frequently at certain times of the year remains unclear, therefore research on this topic should be continued, as well as on the effects of PM10 and benzo(a)pyrene exposure.

Left Heart Syndrome

A 30-year-old female with a history of seizure disorder and hypoplastic left heart syndrome treated with a Norwood procedure in 1986 followed by a modified non-fenestrated Fontan (Left SVC to IVC to pulmonary arteries) with a known baffle leak presented to the emergency department. On day of presentation, the patient became unresponsive, with perioral cyanosis, rightward gaze and a left facial droop near the end of a platelet transfusion. An emergent non-contrast head CT revealed intracranial air in the right MCA distribution. She was taken to the hyperbaric chamber and was treated with a U.S. Navy Table 6 in a multiplace chamber with no extensions. Ten minutes into the treatment patient became more alert and spontaneously asked questions. The following day she was treated with a U.S. Navy Table 5. Patient had repeat CT of the head, which showed resolution of intracerebral gas and small areas of ischemia in right frontal lobe and right caudate. On hospital day five neurologic exam was normal, with 5/5 strength and no residual deficits. Treating the patient was a concern because patient has a single ventricle, in which the pulmonary artery is connected directly to the vena cava. There is very little data regarding the effects of hyperbaric oxygen (HBO2) therapy on single-ventricle physiology. Only two case reports of three pediatric patients treated with HBO2 for CAGE in a similar setting are known. In these cases the patients had improvements in their symptoms following HBO2. These cases and ours indicate HBO2 is feasible and indicated for CAGE in patients with cyanotic congenital heart disease.

Left Heart Syndrome

Children born with hypoplastic left heart syndrome are at high risk for serious morbidity, growth failure, and mortality during the interstage period, which is the time from discharge home after first-stage hypoplastic left heart syndrome palliation until the second-stage surgical intervention. The single-ventricle circulatory physiology is complex, fragile, and potentially unstable. Multicenter initiatives have been successfully implemented to improve outcomes and optimize growth and survival during the interstage period. A crucial focus of care is the comprehensive family training in the use of home surveillance monitoring of oxygen saturation, enteral intake, weight, and the early recognition of “red flag” symptoms indicating potential cardiopulmonary or nutritional decompensation. Beginning with admission to the intensive care unit of the newborn with hypoplastic left heart syndrome, nurses provide critical care and education to prepare the family for interstage home care. This article presents detailed nursing guidelines for educating families on the home care of their medically fragile infant with single-ventricle circulation.

Left Heart Syndrome

Background: Infants with Hypoplastic Left Heart Syndrome (HLHS) following the Norwood procedure have the worst survival among infant heart transplant (HT) recipients. The Single Ventricle Reconstruction (SVR) trial collected vital status and HT data in 920 eligible patients (pts) and prospective preoperative, operative and post-operative data in 554 randomized pts. This trial provides a unique opportunity to evaluate predictors of the need for HT in HLHS infants. Methods: The public use SVR database was used to analyze factors associated with listing for HT and mortality on the wait list and in HT pts. Pts listed for HT were compared with those who survived without listing. Results: Among 920 eligible pts, 41 were listed for HT and follow up data was available in 33/554 pts. 25 pts underwent HT. The median age at listing was 135 days (6 [[Unable to Display Character: &#8211;]] 713 days). All pts listed were status 1A, except for 2 at status 7 and 1 at status 2. Mean RV fractional area change at birth was significantly lower in the listed group (29±8% vs.35±9, p<0.05). ECMO/ CPR, and need for pacemaker were also more common in listed pts compared to the unlisted group. Gestational age, anatomic diagnosis of aortic atresia, AV valve insufficiency and the number of catheterization interventions were not risk factors for HT listing. The median time from listing to HT was 47 days (2 - 340 days). ECMO or VAD support was used in 10 pts prior to HT. Wait list mortality was 29% with a median time to death of 134 days (10 [[Unable to Display Character: &#8211;]] 707 days). Causes of death on the wait list included cardiac (8 pts), renal (1 pt), surgical (1 pt) and other (2pts). Mortality after HT was 36% with a median time to death of 197 days (48-658 days). Overall mortality after listing, including after HT, was 51%; younger age at listing was associated with increased mortality (292 vs 149 days, p<0.04). Conclusion: HT as a rescue procedure for HLHS in the first year of life carries a significant risk of mortality.
