  Fig. 2. Changes in cardiac function before (a) and after (b) living-donor renal transplantation by transthoracic echocardiography. Left ventricular ejection fraction, left ventricular end-diastolic diameter, and left ventricular end-systolic diameter were 30%, 57 mm, and 50 mm at the preoperative point (a) and 50%, 50 mm, and 38 mm at postoperative day 180 (b), respectively. Severity of mitral regurgitation, effective regurgitant orifice area (proximal isovelocity surface area), and tricuspid regurgitant pressure gradient were severe, 0.25 cm2, and 30 mmHg at the preoperative point (a) and mild, 0.12 cm2, and 21 mmHg at the postoperative day 180 (b), respectively. The above results show that the patient’s cardiac function and severe mitral regurgitation improved to a degree that indicated that cardiac surgery was no longer necessary
