RESUMO
Patients with congenitally-corrected transposition of the great arteries (ccTGA) commonly develop significant systemic tricuspid valve regurgitation and systemic right ventricular dysfunction in adulthood, both of which presenting a therapeutic dilemma for the care team. Here we describe the case of a 35-year-old male with congenitally-corrected transposition of the great arteries who presented with severe systemic tricuspid valve regurgitation, biventricular systolic failure, and pulmonary hypertension. Due to prohibitive surgical risk, he underwent percutaneous tricuspid valve repair via MitraClip placement. Post-procedure, he demonstrated rapidly improved symptoms and sustained echocardiographic and hemodynamic evaluations. Few reports exist describing the safety and feasibility of the MitraClip procedure on a systemic tricuspid valve, but to our knowledge, this is the first to describe invasive hemodynamic improvements in patients with this degree of cardiopulmonary sequelae from the congenital lesion. There may be optimism for the MitraClip procedure as "bridge to list" in patients with ccTGA otherwise initially ineligible for surgical valve intervention or transplant.
