Pedrizetti et al. studied the fluid mechanics inside the left coronary heart in 40 randomized patients with mechanical and tissue synthetic coronary heart valves. Using echocardiography they quantitatively analyzed the velocity discipline within the left coronary heart and discovered that the sufferers with synthetic mitral valves had a constant counterclockwise movement, instead of the regular clockwise circulation this is characteristic of regular transmitral drift.
To in addition represent this counterclockwise stream a numerical simulation changed into achieved which backed up the statistics taken from the echocardiograph observe.
This flipped vortex flow should result in similarly complications in the affected person who had mitral valve alternative surgical procedure as it became determined to cause stagnation points, crossed flows, elevated strength necessities and stress shifts from the lateral to the septal wall in the left coronary heart.
