Dear Author,

Thank you for the astute observation regarding the distinction between Grant's findings and those of isolated left ventricular noncompaction.

I think Dr. Lurie's article is also relevant to isolated noncompaction. Grant's case occurred in the setting of pulmonary atresia and was therefore not “isolated,” but secondary to the abnormal hemodynamics. http://www.ncbi.nlm.nih.gov/pubmed/22176755

Grant did report a case of pulmonary atresia with intact ventricular septum. Examination of figures four and five exhibit a vessel of Wearn.

Relationship of pulmonary atresia with intact ventricular septum to the vessels of Wearn, similar to Grant's work: 1. http://www.ncbi.nlm.nih.gov/pubmed/23332812

Aortic atresia with mitral stenosis has also been associated with the vessels of Wearn: Comparable to the hypertensive right ventricle of PAIVS, the hypertensive left ventricle of AA/MS likely resulted in more prominent sinusoids and vessels of Wearn as in the following case. 1. http://www.ncbi.nlm.nih.gov/pubmed/22498086<br> 2. https://twitter.com/BrettSnodgrass1/status/418829863609331712

Comments and suggestions are always welcome. Thank you kindly.
