A 72 year-old man undergoes mitral valve replacement for degenerative mitral valve disease as well as CABG x 1 with a saphenous vein graft to the OM1. The valve could not be repaired due to severe calcification of the leaflets. Several minutes after coming off bypass a large amount of dark blood is observed welling up from the posterior pericardium. Which of the following is false regarding this complication?

Which of the following mitral valve approaches risks injury to the sinus node artery?

A 52-year-old woman with a long-standing mitral regurgitation presents for elective mitral valve repair. Upon inspection there is excessive, thickened posterior leaflet tissue and the annulus is dilated and calcified. A quadrangular resection of the posterior leaflet and ring annuloplasty is performed however, after separating from CPB the patient is unstable and intra-operative TEE demonstrates systolic anterior motion of the anterior leaflet, with left ventricular outflow tract obstruction and mitral regurgitation. Which of the following may have prevented this complication?

An 82 year old male presents with new onset shortness of breath. Echocardiography shows thickened mitral and tricuspid valves, both of which have severe regurgitation. The leaflets were described as pliable, with restricted mobility of the leaflet tips, resulting in doming and a “hockey-stick” appearance in diastole. Appropriate treatment includes:
