Abstract

Right ventricular failure is a mechanism of hemodynamic collapse in acute aortic dissection. Mostly RV failure happens as a result of coronary malperfusion secondary to compression of right coronary artery ostium by the false lumen of type A aortic dissection or the dissection flap involving this coronary artery. Another mechanism is compression of pulmonary artery and an acute rise of pulmonary pressure below the level of obstruction, which is rarely reported. Herein, we presented an 82-year-old man who was admitted with type A aortic dissection in whom echocardiographic examination revealed right pulmonary artery compression resulting in acute right ventricular failure.
