One of the main reasons is the presumed risk for residual aortic regurgitation (AR). However, case reports and small case series have suggested that TAVI can be successfully performed with acceptable clinical outcomes in high-risk patients with BAV. Within the large German TAVI Registry, we sought to evaluate TAVI in older high-risk patients with BAV. From January 2009 to June 2010, a total of 1,424 patients with severe aortic stenosis undergoing TAVI were prospectively enrolled into the German TAVI Registry. For the present analysis, patients with valve-in-valve procedures were excluded and those with BAV (n = 38, 3%) were compared with those with tricuspid aortic valve (TAV; n = 1357, 97%). Patient characteristics did not markedly differ and procedural success was very high in both groups. There was a higher rate of relevant AR (≥II) after TAVI among patients with BAV (25 vs 15%, p = 0.05), whereas pacemakers were more often implanted in patients with TAV (17% vs 35%, p = 0.02). Thirty-day mortality rate was similar in both cohorts (11% vs 11%). In a Cox proportional regression analysis, BAV was not associated with higher 1-year mortality rate (hazard ratio 0.64, 95% confidence interval 0.29 to 1.41). In selected patients with BAV, TAVI can be performed with a satisfactory clinical result. Although the risk for relevant AR seems to be greater among patients with BAV, 30-day and 1-year mortality rates were not elevated compared with patients with TAV.

- Four patients with Sillence type I osteogenesis imperfecta and mild bone fragility, complicated by left ventricular cardiac valvular disease and cardiac tissue fragility caused by type I collagen mutations.
- Vandersteen AM, Lund AM, Ferguson DJ, Sawle P, Pollitt RC, Holder SE, Wakeling E, Moat N, Pope FM.Author information Ehlers-Danlos Syndrome National Diagnostic Service, North West London Hospitals NHS Trust, Harrow, Middlesex, United Kingdom.AbstractOsteogenesis imperfecta (OI) type I is a hereditary disorder of connective tissue (HDCT) characterized by blue or gray sclerae, variable short stature, dentinogenesis imperfecta, hearing loss, and recurrent fractures from infancy. We present four examples of OI type I complicated by valvular heart disease and associated with tissue fragility. The diagnosis of a type I collagen disorder was confirmed by abnormal COL1A1 or COL1A2 gene sequencing. One patient was investigated with electrophoresis of collagens from cultured skin fibroblasts, showing structurally abnormal collagen type I, skin biopsy showed unusual histology and abnormal collagen fibril ultra-structure at electron microscopy. The combined clinical, surgical, histological, ultra-structural, and molecular genetic data suggest the type I collagen defect as contributory to cardiac valvular disease. The degree of tissue fragility experienced at cardiac surgery in these individuals, also reported in a small number of similar case reports, suggests that patients with OI type I need careful pre-operative assessment and consideration of the risks and benefits of cardiac surgery. © 2013 Wiley Periodicals, Inc.

- A bicuspid aortic valve (BAV) is most commonly a congenital condition of the aortic valve where two of the aortic valvular leaflets fuse during development resulting in a valve that is bicuspid instead of the normal tricuspid configuration.
