Currently, the most convincing evidence as to the relationship between VaD and nutrition exists for micronutrients, particularly Vitamin E and C. Exploration of nutrition at the macronutrient level and additional long term prospective cohort studies are warranted to better understand the role of nutrition in VaD disease development and progression. At present, challenges in this research include limitations in sample size, which was commonly cited. Also, a variety of diagnostic criteria for VaD were employed in the studies reviewed, indicating the need for constructing a correct nosological definition of VaD for consistency and conformity in future studies and accurate clinical diagnosis of VaD.

We present a case of a 65-year-old man who presented with atrial flutter and dilation of right heart was noted on transthoracic echocardiography. Transesophageal echocardiography revealed a large sinus venosus atrial septal defect close to superior vena cava and anomalous connection of right superior pulmonary vein. Additionally, real time three-dimensional transesophageal echocardiography provided superior spatial details and demonstrated the size, location of the defect and its spatial relationship to the surrounding structures. Patient underwent successful surgical repair.
