‘An attempt at visualizing the Fourth Dimension: Take a point, stretch into a line, curl it into a circle, twist it into a sphere, and punch through the sphere’. Albert Einstein

Wang et al.1 provide novel pathophysiological information on patients with diastolic heart failure, by exploring the fourth dimension of cardiac function: left ventricular (LV) twist. The complex active and passive physiological events occurring during the heart cycle are related to the complex structure of the heart, which is a helix that contains an apex. Lower (17th century) described the cardiac helix form as having an apical vortex, in which the muscle fibres go from outside in, in a clockwise way, and from inside out, in a counter-clockwise direction.2 Nature contains many pathways of clockwise and counter-clockwise spirals (reciprocal spirals), e.g. the flower buds of a daisy, the sea shell, and even human fingertips. Dr Torrent-Guasp compared the structure of . . . [Full Text of this Article]
