correct nomenclature Heart 2002;87:503–506 Although we had indicated that having studied the book of McAlpine, we also would use anatomically appropriate nomenclature, for a long time we failed to follow our own advice In this editorial, we stressed again the importance of adopting the suggestions of McAlpine Dobrzynski H, Boyett MR, Anderson RH New insights into pacemaker activity: promoting understanding of sick sinus syndrome Circulation 2007;155:1921–1932 In this review, celebrating the centenary of discovery of the sinus node by Keith and Flack, we review the history of the discovery and put the anatomic findings into the context of the subsequent researches into electrophysiology and developmental biology McAlpine WA Heart and Coronary Arteries An Anatomical Atlas for Clinical Diagnosis, Radiological Investigation, and Surgical Treatment Springer-Verlag: Berlin; 1975 An important book, now out of print, that stresses the importance of describing the heart as it is positioned within the body The dissections illustrated are exquisite, and it is deserving of greater recognition than it has achieved Merrick AF, Yacoub MH, Ho SY, Anderson RH Anatomy of the muscular subpulmonary infundibulum with regard to the Ross procedure Ann Thorac Surg 2000;69:556–561 We pointed out that, unless the pulmonary valve was truly supported by its muscular infundibular sleeve, it would be impossible to remove the valve for use as an autograft in the Ross procedure The corollary of this finding is that there is no “outlet septum” interposed between the back wall of the right ventricular outflow tract and the aortic valvar sinuses Mori S, Spicer DE, Anderson RH Revisiting the anatomy of the living heart Circ J 2016;80:24– 33 In this review, we showed how, using multidetectorrow computed tomography, it is now possible to conduct virtual dissection, revealing the details of cardiac anatomy with as much, if not more, detail as when the prosector holds the heart in his or her hands in the dissecting room Sutton JP III, Ho SY, Anderson RH The forgotten interleaflet triangles: a review of the surgical anatomy of the aortic valve Ann Thorac Surg 1995;59:419–427 In this investigation, we showed that because of the semilunar nature of the attachments of the arterial valvar leaflets, crescents of ventricle were incorporated into the bases of the arterial sinuses, while triangles of fibrous tissue extended to the sinutubular junction as parts of the ventricle We also emphasized that because of these anatomic arrangements, the arterial valves did not possess an “annulus” in terms of a circular structure supporting the leaflets in cord-like fashion Instead, the arrangement resembled a crown Tawara S Das Reizleitgssystem des Saugetierherzens Gustav Fischer: Jena; 1906 In this monumental monograph, Tawara clarified the arrangement of the specialized muscular axis responsible for atrioventricular conduction, demonstrating for the first time the existence of the atrioventricular node As was emphasized by Keith in his autobiography, this research ushered in a new epoch of understanding The book is now available in an English translation published by Imperial College Press Victor S, Nayak VM Definition and function of commissures, slits and scallops of the mitral valve: analysis in 100 hearts Asia Pac J Thorac Cardiovasc Surg 1994;3:10–16 In this work, Solomon Victor pointed out that examining the mitral valve in its closed position negated the need to define “commissures” on
