""Myocardial bridging is characterized by intra-myocardial course of a segment of an epicardial coronary artery, leading to systolic compression. In most cases, it is considered a benign condition but rarely has been associated with serious cardiac [http://www.selleckchem.com/products/MK-2206.html MK2206] events like myocardial infarction and sudden death. We describe a 25-year-old man with known d-transposition of the great arteries (d-TGA) status post-Mustard procedure who presented with palpitations and chest pain. Cardiac catheterization revealed complete systolic compression of a myocardial bridging segment of the left anterior descending artery and also complete compression of the first septal perforator during episodes of ectopic atrial tachycardia. No percutaneous or surgical interventions were performed. Symptoms improved after cautious use of beta-blockers. This appears to be the first report of symptomatic myocardial bridging in an adult patient with d-TGA. ""Background.? Hyponatremia (HN) is relatively common in adults with congenital heart disease and is a powerful predictor of mortality. However, the precise relationship of HN to the Fontan pathophysiology remains unknown. Purpose.? Our study aimed to clarify the association of HN to the Fontan pathophysiology. [http://en.wikipedia.org/wiki/TRIB1 TRIB1] Methods and Results.? We measured the plasma sodium (Na) level in 169 consecutive Fontan patients (78 children) and HN (��137?mEq/L) was observed in 50 patients (30% of the total patients, 31% of the children). The HN patients showed a lower peak oxygen uptake (VO2) with a greater New York Heart Association class (P [http://www.selleckchem.com/products/pci-32765.html Ibrutinib in vivo] correlated with the Na levels. In the children, diuretic use and the PRA independently determined the Na levels without any association to the CVP or peak VO2. During a median follow-up of 2.1 years, the HN in addition to the CVP and peak VO2 independently predicted the unscheduled hospitalizations in all patients, while the HN was the only independent predictor of the hospitalizations in the adult patients (hazard ratio: 3.1, 95% confidence interval 1.2�C8.0, P= .021). Conclusions.? Child and adult Fontan patients exhibited a high prevalence for HN that closely reflected some neurohumoral activation and predicted adverse clinical events, especially in adult Fontan patients. ""Objectives.? To investigate functional health status among adults previously operated for aortic coarctation (CoA) compared with healthy subjects; to assess the influence of medication and exercise capacity on patients' functional health. Design.? Questionnaire-based investigation among 119 patients who underwent surgical repair of CoA during 1965�C1985 and 36 age- and gender-matched healthy subjects using the SF-36 health survey.
