Hyperdynamic Valve: A Rare Case of Ehlers-Danlos Syndrome

Sofia Xavier Pires, Gabriela Pereira, David Paiva, Filipa Cordeiro, Magda Fernandes, Jorge Cotter


<p>Ehlers-Danlos syndrome is a group of rare genetic disorders of collagen characterized by skin hyperextensibility, joint hypermobility and tissue fragility. The authors describe a rare case of a 52-year-old woman that presented to the clinic with chronic joint pain and talipes equinovarum since childhood. Large eyes, sunken cheeks, thin nose and lobeless ears were noticed on clinical examination. Beighton joint hypermotility criteria were met with a positive Walker and Steinberg sign, elbow extension superior to 10 and knee extension in genu recurvatum more than 10. An aortic diastolic grade III/VI heart murmur was heard. The complementary study was unremarkable. Moderate aortic insufficiency was found on transthoracic echocardiogram. Genetic testing confirmed positivity for COL1A2, a gene that encodes pro-alpha2 chain type of collagen, which causes cardiac-valvular Ehlers-Danlos syndrome. Authors intend to warn to collagen-related syndromes, since severe complications are associated with a reduced life expectancy for individuals with this condition.</p><br /><br /><br />J Med Cases. 2021;12(7):284-287<br />doi: https://doi.org/10.14740/jmc3692
