63-year survival after Blalock-Taussig shunt operation in a patient with single ventricle, tricuspid atresia, and pulmonary stenosis.

Abstract: A 63-year-old female with complex congenital heart disease underwent a classical Blalock-Taussig (B-T) shunt operation at the age of 3 years in 1948. The cardiac morphology was not amenable to further definite surgical repair in that period of time. With this palliative operation, the patient survived to the age of 63 years and now presented with exercise intolerance and significant desaturation. Cardiac catheterization with angiography revealed a severe stenosis of the B-T shunt at the pulmonary end. Balloon dilation and stent implantation could be performed successfully. Follow-up after 5 months showed a patent B-T shunt and an increase of oxygen saturation from 65% to 80% and mild improvement of pulmonary blood flow and exercise tolerance.

Pre-competition cardiac screening in professional handball players – setting up at the EHF European Handball Championship 2010 in Austria

Abstract: In many sports, regular cardiac screening for exercise-associated sudden cardiac death is still not provided. To set up the current situation in top-skilled handball players qualified for the 2010 European Handball Championship in Austria, a standardised questionnaire was sent to every team. The fact that only 42.7% of the players returned the questionnaire may lead to the conclusion that the awareness of the problem is quite low. However, 82% of these players have been screened according to current recommendations. Half of the teams were screened inhomogeneously: 5 players (4.1%) have not been screened within the last years, 1 athlete (0.8%) was screened without an ECG. While 69% of the athletes got their first screening only after the age of 18, 16 players (13.1%) never went through a specific screening ever. We identified 17 athletes (13.9%) with a highly suspicious history, 2 of them (1.6%) never underwent a medical screening at all.

Retinal findings in carriers of monoallelic ABCC6 mutations.

Abstract: Aim Biallelic ABCC6 mutations cause pseudoxanthoma elasticum, a systemic disease characterised by calcification of elastic tissue and a specific retinal phenotype. In this study, we investigated if monoallelic ABCC6 mutations are also associated with retinal alterations. Methods In this prospective, cross-sectional, monocentre case–control study, carriers of monoallelic ABCC6 mutations were investigated and compared with age-matched controls. The retinal phenotype was characterised using fundus photography, fundus autofluorescence, confocal near-infrared reflectance imaging, spectral domain optical coherence tomography and in selected cases late-phase indocyanine green angiography. Results Thirty-eight subjects carrying monoallelic ABCC6 mutations (mean age 70.2 years, range 50–90, 26 female) were examined and compared with 77 age-matched controls (mean age 69.9 years, range 50–93, 43 female). Retinal alterations were more frequently found in carriers of monoallelic ABCC6 mutations compared with controls (50% vs 33.8%, p=0.107) with increasing prevalence at older age. Typical findings were peripapillary atrophy (37% vs 23%, p=0.184), pattern dystrophy-like changes (24% vs 12%, p=0.109), reticular pseudodrusen (21% vs 5%, p=0.019), small angioid streaks (8% vs 1%, p=0.105), choroidal neovascularisations and atrophic lesions (both 8% vs 0%, p=0.034). Late-phase indocyanine green angiography showed a reduced cyanescence centred to the posterior pole in 11 of 14 examined subjects with monoallelic ABCC6 mutations. Conclusion The findings of this study indicate a possible ocular ABCC6 haploinsufficiency phenotype. Due to its late-onset and phenotypic similarities, misinterpretation as age-related macular degeneration is possible.
