Asd Closure

The aim of the study was to review our experience with atrial septal defect (ASD) closure with a fenestrated patch in patients with severe pulmonary hypertension. Between July 2004 and February 2009, 16 patients with isolated ASD underwent closure with a fenestrated patch. All patients had a secundum type ASD and severe pulmonary hypertension. Patients ranged in age from 6 to 57 years (mean � SD, 34.9 � 13.5 years). The follow-up period was 9 to 59 months (mean, 34.5 � 13.1 months). The ranges of preoperative systolic and pulmonary arterial pressures were 63 to 119 mm Hg (mean, 83.8 � 13.9 mm Hg) and 37 to 77 mm Hg (mean, 51.1 � 10.1 mm Hg). The ranges of preoperative values for the ratio of the pulmonary flow to the systemic flow and for pulmonary arterial resistance were 1.1 to 2.7 (mean, 1.95 � 0.5) and 3.9 to 16.7 Wood units (mean, 9.8 � 2.9 Wood units), respectively. There was no early or late mortality. Tricuspid annuloplasty was performed in 14 patients (87.5%). The peak tricuspid regurgitation gradient and the ratio of the systolic pulmonary artery pressure to the systemic arterial pressure were decreased in all patients. The New York Heart Association class and the grade of tricuspid regurgitation were improved in 13 patients (81.2%) and 15 patients (93.7%), respectively. ASD closure in patients with severe pulmonary hypertension can be performed safely if we create fenestration. Tricuspid annuloplasty and a Cox maze procedure may improve the clinical result. Close observation and follow-up will be needed to validate the long-term benefits.

Transient Tricuspid Regurgitation

A 14 year old girl presented with severe tricuspid regurgitation after she was diagnosed with “transient tricuspid regurgitation of the newborn”. In the neonatal period she had presented with severe tricuspid regurgitation without an obvious underlying anatomical cause. This spontaneously regressed during the first months of life. She was dismissed from follow up at the age of 5 years after complete normalisation of the clinical and echocardiographic examination. The subsequent evolution and management of the patient, as well as the possible pathogenesis responsible for the unusual clinical course, is discussed. This case stresses the importance of long term follow up of patients with transient tricuspid regurgitation.

Background: Chronic kidney disease following liver transplantation is a major long-term complication. Most liver transplant recipients with kidney failure will be treated with dialysis instead of kidney transplantation due to noneligibility and shortage in organ availability. In this population, the role of peritoneal dialysis (PD) as a modality of kidney replacement therapy (KRT) remains unclear. Objective: To determine the feasibility regarding safety, technique survival, and dialysis efficiency of PD in liver transplant recipients requiring KRT for maintenance dialysis. Design: Systematic review. Setting: Interventional and observational studies reporting the use of PD after liver transplantation. Patients: Adult liver transplant recipients with kidney failure treated with maintenance KRT. Measurements: Extracted data included eligibility criteria, study design, demographics, and PD modality. The following outcomes of interest were extracted: rate of peritonitis and microorganisms involved, noninfectious peritoneal complications, technique survival, and kidney transplantation-censored technique survival. Non-PD complications included overall survival, liver graft dysfunction, and hospitalization rate. Methods: The following databases were searched until July 2020: MedLine/PubMed, EMBASE, CINAHL, and Cochrane Library. Two reviewers independently screening all titles and abstracts of all identified articles. Due to the limited sample size, observational designs and study heterogeneity expected, no meta-analysis was pre-planned. Descriptive statistics were used to report all results. Results: From the 5263 identified studies, 4 were included in the analysis as they reported at least 1 outcome of interest on a total of 21 liver transplant recipients, with an overall follow-up duration on PD of 19.0 (Interquartile range [IQR]: 9.5-29.5) months. Fifteen episodes of peritonitis occurred in a total cumulative PD follow-up of 514 patient-months, representing an incidence rate of 0.35 per year. These episodes did not result in PD technique failure, mortality, or impairment of liver graft function. Limitations: Limitations include the paucity of studies in the field and the small number of patients included in each report, a risk of publication bias and the impossibility to directly compare hemodialysis to PD in this population. These results, therefore, must be interpreted with caution. Conclusions: Based on limited data reporting the feasibility of PD in liver transplant recipients with kidney failure, no signal was associated with an increased risk of infectious complications. Long-term studies evaluating this modality need to be performed. Registration (PROSPERO): CRD42020218374.

End Stage

Patients after LT due to combined HBV/HDV infection are considered to be high-risk patients for recurrence of hepatitis B and D. To date, life-long prophylaxis with hepatitis B immunoglobulin (HBIG) and replication control with nucleos(t)ide analogs (NA) remains standard. We examined the course of 36 patients that underwent liver transplantation from 1989 to 2020 for combined HBV/HDV-associated end-stage liver disease in this retrospective study. Seventeen patients eventually discontinued HBIG therapy for various reasons. Their graft function, histopathological findings from routine liver biopsies and overall survival were compared with those that received an unaltered NA-based standard regimen combined with HBIG. The median follow-up was 204 and 227 months, respectively. The recurrence of HBV was 25% and did not differ between the groups of standard reinfection prophylaxis NA/HBIG (21.1%) and HBIG discontinuation (29.4%); (p = 0.56). No significant differences were found regarding the clinical course or histopathological aspects of liver tissue damage (inflammation, fibrosis, steatosis) between these two groups. Overall, and adjusted survival did not differ between the groups. Discontinuation of HBIG in stable patients after LT for combined HBV/HDV did not lead to impaired overall survival or higher recurrence rate of HBV/HDV infection in this long-term follow-up. Therefore, the recommendation of the duration of HBG administration must be questioned. The earliest time of discontinuation remains unclear.
