A case of right ventricular outflow tract obstruction after minimally invasive aortic valve replacement

Abstract

Minimally invasive aortic valve replacement is commonly used to treat aortic valve disease through smaller incisions and upper hemisternotomy. No major differences in postoperative outcomes have been reported compared with full sternotomy aortic valve replacement. In this case report, we present a rare complication of right ventricular outflow tract obstruction after minimally invasive aortic valve replacement.

Right Ventricular Outflow Tract Obstruction in Adults: A Systematic Review and Meta-analysis

“…In some instances, the investigative workup suggested the diagnosis, or the workup could not be performed and the diagnosis was confirmed on autopsy following the patient's death. 20 , 27 , 29 , 37 , 57 , 59 , 129 , 243 There were no predetermined echocardiographic diagnostic criteria across the studies. In one study, RVOTO is explicitly defined as a flow velocity of >2.0 m/s (16 mm Hg) on continuous wave Doppler TTE across the RVOT; 102 however, this specific criterion is not universally mentioned in all studies.…”
