Diller G-P, Braeutigam A, Kempny A, Uebing A, Alonso-Gonzalez R, Swan L, Babu-Narayan SV, Baumgartner H, Dimopoulos K, Gatzoulis AAet al., 2015, Depression requiring anti-depressant drug therapy in adult congenital heart disease: prevalence, risk factors, and prognostic value, European Heart Journal, Vol: 37, Pages: 771-782, ISSN: 1522-9645

Background Depression is prevalent in adults with congenital heart disease (ACHD), but limited data on the frequency of anti-depressant drug (ADD) therapy and its impact on outcome are available.Methods and results We identified all ACHD patients treated with ADDs between 2000 and 2011 at our centre. Of 6162 patients under follow-up, 204 (3.3%) patients were on ADD therapy. The majority of patients were treated with selective serotonin-reuptake inhibitors (67.4%), while only 17.0% of patients received tricyclic anti-depressants. Twice as many female patients used ADDs compared with males (4.4 vs. 2.2%, P < 0.0001). The percentage of patients on ADDs increased with disease complexity (P < 0.0001) and patient age (P < 0.0001). Over a median follow-up of 11.1 years, 507 (8.2%) patients died. After propensity score matching, ADD use was found to be significantly associated with worse outcome in male ACHD patients [hazard ratio 1.44 (95% confidence interval 1.17–1.84)]. There was no evidence that this excess mortality was directly related to ADD therapy, QT-prolongation, or malignant arrhythmias. However, males taking ADDs were also more likely to miss scheduled follow-up appointments compared with untreated counterparts, while no such difference in clinic attendance was seen in females.Conclusions The use of ADD therapy in ACHD relates to gender, age, and disease complexity. Although, twice as many female patients were on ADDs, it were their male counterparts, who were at increased mortality risk on therapy. Furthermore, males on ADDs had worse adherence to scheduled appointments suggesting the need for special medical attention and possibly psychosocial intervention for this group of patients.

D'Alto M, Merola A, Dimopoulos K, 2015, Pulmonary hypertension related to congenital heart disease: A comprehensive review, Global Cardiology Science and Practice, Vol: 2015

Pulmonary arterial hypertension (PAH) is a serious complication of congenital heart disease, causing an increase in morbidity and mortality. The progressive and irreversible pulmonary vascular disease is more often the consequence of a significant, uncorrected, left-to-right shunt. The rise in pulmonary vascular resistance may lead to the reversal of the shunt and cyanosis, condition known as Eisenmenger syndrome. The management of this population is challenging and requires specific expertise both for diagnosis and follow-up. The progress in the understanding of the underlying pathophysiology of this condition has promoted recent pharmacological trials. New therapeutic options are now available that could improve the longterm prognosis and the quality of life of these patients, but several controversial points still remain and need to be addressed. 2015 ElMaghawry, licensee Bloomsbury Qatar Foundation Journals.

Background In patients with acquired heart failure, hypoalbuminaemia is associated with increased risk of death. The prevalence of hypoproteinaemia and hypoalbuminaemia and their relation to outcome in adult patients with congenital heart disease (ACHD) remains, however, unknown.Methods Data on patients with ACHD who underwent blood testing in our centre within the last 14 years were collected. The relation between laboratory, clinical or demographic parameters at baseline and mortality was assessed using Cox proportional hazards regression analysis.Results A total of 2886 patients with ACHD were included. Mean age was 33.3 years (23.6–44.7) and 50.1% patients were men. Median plasma albumin concentration was 41.0 g/L (38.0–44.0), whereas hypoalbuminaemia (<35 g/L) was present in 13.9% of patients. The prevalence of hypoalbuminaemia was significantly higher in patients with great complexity ACHD (18.2%) compared with patients with moderate (11.3%) or simple ACHD lesions (12.1%, p<0.001). During a median follow-up of 5.7 years (3.3–9.6), 327 (11.3%) patients died. On univariable Cox regression analysis, hypoalbuminaemia was a strong predictor of outcome (HR 3.37, 95% CI 2.67 to 4.25, p<0.0001). On multivariable Cox regression, after adjusting for age, sodium and creatinine concentration, liver dysfunction, functional class and disease complexity, hypoalbuminaemia remained a significant predictor of death.Conclusions Hypoalbuminaemia is common in patients with ACHD and is associated with a threefold increased risk of risk of death. Hypoalbuminaemia, therefore, should be included in risk-stratification algorithms as it may assist management decisions and timing of interventions in the growing ACHD population.
