Abstract :Congenital secundum atrial septal defect insert ignore into journalissuearticles values(ASD); and membranous ventricular septal defect insert ignore into journalissuearticles values(VSD); were diagnosed in a 1-day-old Holstein-Friesian calf necropsied in the Department of Pathology of Mehmet Akif Ersoy University. The secundum atrial septal defect was 32.9 × 23.1 mm in width and was elliptical. The membranous ventricular septal defect was 25.3 × 18.5 mm in width and was round to oval in shape.
