We report a case of a 49-year-old man who presented to our hospital with longstanding shortness of breath on exertion. He was finally diagnosed as right ventricular outflow tract obstruction and referred for surgical correction. The patient had a history of descending aorta dissection which was treated by thoracic stent grafting. By that time right-sided aortic arch was diagnosed. The coexistence of right ventricular outflow tract obstruction and right sided aortic arch in the same patient is very rare, to the best of our knowledge.

Symptoms are similar to those of aortic stenosis and are due to LV diastolic dysfunction and myocardial ischemia in the absence of epicardial coronary narrowing. Goals of treatment include symptomatic control, resolution of hemodynamic abnormalities and their sequelae, reduction of sudden cardiac death risk and screening of family members. Left ventricular outflow tract obstruction at rest is a predictor of severe symptoms, heart failure, and death. The majority of patients are managed medically, predominantly with b-blockers and calcium channel blockade. Disopyramide, a negative inotrope, can be used in cases with persistently high resting gradients. To prevent sudden cardiac death, implantable cardioverterdefibrillators are used aggressively .

We report the case of a 77-year-old Caucasian man presenting with dysphagia and dyspnea secondary to an aberrant right subclavian artery aneurysm and describe our technique for open surgical repair.

From 1996 to 2003, 4 cases of solitary mediastinal cystic lymphangioma were managed in our department. The clinicopathologic characteristics were recorded and analyzed. The incidence proved to be 1.2% among all cases of mediastinal masses admitted to our department. All patients were asymptomatic, they shared common radiologic features, and all were managed by radical surgical excision. No recurrence or mortality were noted during follow-up ranging from 2 to 7 years. Complete excision of this benign entity has an excellent prognosis.

Previous existence or the rapid development of collateral vessels between the right and the left coronary arteries may prevent ischemia [1, 3]. These children will survive to adolescence or adulthood, whereas about 80% to 90% will die during the first year of life from heart failure or sudden cardiac death if surgical correction is not performed [3]. Survival to adulthood is unusual, and patients older than 50 years are very rare [4].
