Minimally invasive treatment strategy for severe congenital pulmonary valve insufficiency and pulmonary artery aneurysmal dilatation: a case report

Pulmonary valve insufficiency most commonly occurs following various precordial interventions, including repair of tetralogy of Fallot, balloon dilatation for pulmonary stenosis, and surgical or percutaneous treatment for pulmonary atresia with intact ventricular septum. Isolated congenital pulmonary valve insufficiency is rare, and insufficiency secondary to myxomatous degeneration of the pulmonary valve is even rarer. We report the case of a 16-year-old female with severe pulmonary valve insufficiency and aneurysmal dilatation of the pulmonary artery caused by myxomatous degeneration of the pulmonary valve. The patient underwent minimally invasive surgical treatment, and no regurgitation was observed at one-year follow-up.
