I confirm that I have watched the accompanying video in full before completing these CPD questions and claiming CPD points.:: Yes
1. At approximately what day postconception is the heart described as a single cardiac tube?:: A. Day 7B. Day 14C. Day 23D. Day 35E. Day 50
2. Which structures develop from the sinus venosus region?:: A. Left ventricle, mitral valve, and aortaB. Coronary sinus and a large portion of the right atriumC. Left atrium and pulmonary veinsD. Right ventricle and pulmonary arteryE. Aortic root, aortic arch and descending aorta
3. Persistence of the left anterior cardinal vein can result in which congenital anomaly?:: A. Interrupted IVCB. Persistent right SVCC. Persistent left SVCD. Anomalous pulmonary venous returnE. Double aortic arch
4. What is the primary embryological contribution of the bulbus cordis?:: A. The trabeculated portion of the left ventricleB. The smooth posterior wall of the right atriumC. The atrial appendages for both atriaD. Formation of the aorta and pulmonary arteryE. Formation of the right ventricle and outflow tracts
5. Failure of the septum primum to fuse properly is associated with which defect?:: A. Secundum ASDB. Primum ASDC. Complete AV canal defectD. Gerbode defectE. Patent foramen ovale
6. Which statement regarding the development of the septum secundum is correct?:: A. It forms the floor of the fossa ovalis.B. It develops on the right side of the septum primum.C. It grows from the endocardial cushions toward the roof of the atrium.D. It completely fuses with the septum primum before birth to close the foramen ovale.E. It is a highly flexible, thin membrane that acts as a one-way valve during foetal life.
7. Failure of the septum secundum to develop adequately is associated with which type of atrial septal defect (ASD)?:: A. Primum ASDB. Secundum ASDC. Sinus venosus ASDD. Coronary sinus ASDE. AV canal type
8. What embryological abnormality is associated with cor triatriatum?:: A. Failure of the septum primum to formB. Abnormal migration of neural crest cellsC. Malformation of the endocardial cushionsD. Defective development of the septum secundumE. Failure of the common pulmonary vein to become fully incorporated into the left atrium
9. Which embryological structure primarily develops into the left ventricle?:: A. Bulbus cordisB. Truncus arteriosusC. Sinus venosusD. Primitive ventricleE. Conus cordis
10. What does D-looping result in?:: A. Morphological RV on the left and LV on the rightB. Morphological RV on the right and LV on the leftC. Both ventricles positioned on the leftD. Both ventricles positioned on the rightE. Isolated dextrocardia with situs inversus
