Abstract:
Pulmonary artery (PA) aneurysm is rare, but its true incidence is unclear, because most cases remain asymptomatic. The need for surgical treatment is controversial. We report two cases of surgical treatment of PA aneurysm associated with pulmonary valve (PV) disease in adults. Case1: A 54-year-old woman. She underwent pulmonary valvotomy for pulmonary stenosis (PS) at age 22. She had suffered from palpitations and dyspnea on effort recently. Then progressive changes of pulmonary stenosis-regurgitation (PSR) occurred. After further examinations, she was diagnosed as having PA aneurysm and right ventricular dysfunction with PSR, tricuspid regurgitation and paroxysmal atrial fibrillation. We performed PV replacement, PA aneurysmo-plasty, tricuspid annuloplasty, cryo-MAZE procedure. Case2: A 70-year-old man sufferd recently from dyspnea on effort. The dilatation of the pulmonary artery was pointed out on chest X-ray. PA aneurysm and PS with ventricular arrhythmia were diagnosed. We performed PV commissurotomy and PA aneurysmo-plasty. There were no significant findings of high PA pressure in either case. PA with pulmonary valve disease in the presence of low pulmonary pressure have low risk of rupture and dissection. Surgical treatments are recommended when right ventricular dysfunction or ventricular arrhythmia secondary to pulmonary valve disease is present.
