RESUMO

Multiorgan dysfunction is a concern of Fontan patients. To clarify the pathophysiology of Fontan nephropathy, we characterize renal disease in the long-term observational study. Medical records of 128 consecutive Fontan patients [median age: 22 (range 15-37) years old] treated between 2009 and 2018 were reviewed to investigate the incidence of nephropathy and its association with other clinical variables. Thirty-seven patients (29%) showed proteinuria (n = 34) or < 90 mL/min/1.73 m2 of estimated glomerular filtration rate (eGFR) (n = 7), including 4 overlapping cases. Ninety-six patients (75%) had liver dysfunction (Forns index > 4.21). Patients with proteinuria received the Fontan procedure at an older age [78 (26-194) vs. 56 (8-292) months old, p = 0.02] and had a higher cardiac index [3.11 (1.49-6.35) vs. 2.71 (1.40-4.95) L/min/m2, p = 0.02], central venous pressure [12 (7-19) vs. 9 (5-19) mmHg, p < 0.001], and proportion with > 4.21 of Forns index (88% vs. 70%, p = 0.04) than those without proteinuria. The mean renal perfusion pressure was lower in patients with a reduced eGFR than those without it [55 (44-65) vs. 65 (45-102) mmHg, p = 0.03], but no other variables differed significantly. A multivariable analysis revealed that proteinuria was associated with an increased cardiac index (unit odds ratio 2.02, 95% confidence interval 1.12-3.65, p = 0.02). Seven patients with severe proteinuria had a lower oxygen saturation than those with no or mild proteinuria (p = 0.01, 0.03). Proteinuria or a decreased eGFR differentially occurred in approximately 30% of Fontan patients. Suboptimal Fontan circulation may contribute to the development of proteinuria and reduced eGFR.

RESUMO

We present a 13-year-old boy who had recurrent chest pain with elevated cardiac enzymes and abnormal ST segments in electrocardiogram 36 hours after the second dose of BNT162b2 vaccination. Cardiac MRI and coronary angiography with acetylcholine provocation confirmed myocarditis and vasospastic angina, respectively. Coronary vasospasm may play a pivotal role in the chest pain in COVID-19 vaccine-related myocarditis.

RESUMO

We performed a second puncture of the extracardiac conduit in an 11-year-old Fontan patient to assess the patency of the stent previously deployed in the left pulmonary vein. For the first puncture, a mechanical Brockenbrough needle was selected to puncture the Gore-Tex conduit, an electrical insulator. For the second puncture, the location of that previous hole was detected as an indentation covered with atrial tissue, which is an electrical conductor. The second puncture was performed safely using a radiofrequency transseptal needle.

RESUMO

INTRODUCTION: Pulmonary agenesis is a complete absence of the pulmonary parenchyma, airways, and vasculature unilaterally or bilaterally. Although bilateral cases are lethal, the outcome of unilateral cases remains not well described. We performed a comprehensive literature review to assess the clinical features of pulmonary agenesis. METHODS: Four database sources were searched on October 10, 2021 and two cases were included from our institution. Studies related to the clinical impact of comorbidity and intervention on the survival outcome in pulmonary agenesis were included for full-text review. RESULTS: We identified 259 patients-with right-sided (59%), left-sided (34%), and bilateral agenesis (7%)-among 195 articles and our two cases. Additional anomalies included cardiovascular (40%), skeletal (30%), gastrointestinal (20%), tracheal (20%: all stenoses), and genitourinary (14%) anomalies. Fifty-seven (24%) individuals in unilateral pulmonary agenesis had isolated disease. Outcomes related to survival were not uniformly reported, but the 2-year overall survival rate of unilateral agenesis was 62% and no subsequent death was reported until 13 years of age. The right-sided agenesis was more frequently associated with tracheal stenosis (27% vs. 11%, p = 0.003) than the left-sided disease. A multivariable analysis indicated that tracheal stenosis (hazard ratio [HR]: 2.2, 95% confidence interval [CI]: 1.3-4.1, p = 0.003) and gastrointestinal anomalies (HR: 2.0, 95% CI: 1.1-3.3, p = 0.010) were prognostic factors for mortality. CONCLUSIONS: The poor prognostic factors were tracheal stenosis, right agenesis, and gastrointestinal anomalies. Treatment for these comorbidities is a key point for improving the survival of unilateral pulmonary agenesis.
