SURPRISING DISCOVERIES IN DEPTHS OF HUMAN HEARTS: BLACKNESS AND COLDNESS

Although infrequent, a surprising surgical finding can occur during regular cardiac surgical procedure. We present altogether four patients with strange findings during open heart surgery. Firstly, two female patients with aortic stenosis who were diagnosed with rare autosomal recessive disorder alkaptonuria during aortic valve replacement by black discoloration of stenotic aortic valve and sternal cartilage. The diagnosis was later confirmed histologically and clinical hallmarks such as dark urine and bluish ear cartilage and sclera were observed. The second case pertain to 60-years-old man with pulmonary valve endocarditis due to a 45 mm long sewing needle entrapped into the right ventricle which was successfully removed along with pulmonary valve replacement and tricuspid valve annuloplasty. The third case is 26-yearsold patient with severe aortic valve insufficiency and pseudoaneurysm formation of left coronary sinus presenting two years after aortic valve repair with extraortic ring. The surprising finding was a silicon part of extraortic ring protruding in left sinus of Valsalva which was successfully repaired by pericardial patch along with aortic valve replacement with mechanical valve.
