Pulsatile support using a rotary left ventricular assist device with an electrocardiography-synchronized rotational speed control mode for tracking heart rate variability
We previously developed a novel control system for a continuous-flow left ventricular assist device (LVAD), the EVAHEART, and demonstrated that sufficient pulsatility can be created by increasing its rotationa...

SYNTAX-justified trend toward restricting coronary artery bypass grafting to more serious cases
Since drug-eluting stents (DESs) appeared in Japan, coronary artery bypass grafting (CABG) has been indicated for more severe lesions. To understand the implications of this trend, we compared SYNTAX scores in...

Is the threshold for postoperative prosthesis-patient mismatch the same for all prostheses?
The effective orifice area index (EOAI) is used to define the prosthesis-patient mismatch (PPM) after aortic valve replacement (AVR). However, few studies have so far evaluated whether the cutoff value for PPM...
