Reversibility of Cardiac Dysfunction After Valve Replacement in Elderly Patients With Severe Aortic Stenosis Masafumi Natsuaki, MD, Tsuyoshi Itoh, MD, Shinji Tomita, MD, Kozo Naito, MD The Annals of Thoracic Surgery Volume 65, Issue 6, Pages 1634-1638 (June 1998) DOI: 10.1016/S0003-4975(98)00227-6

Fig 1 Preoperative cardiac dysfunction in group I (n = 29) and group II (n = 21) was noticed in peak ejection rate (PER) as a systolic function. Postoperative peak ejection rate significantly improved in comparison with preoperative value, and was reversible to almost normal values in groups I and II (paired t test). The Annals of Thoracic Surgery 1998 65, 1634-1638DOI: (10.1016/S0003-4975(98)00227-6)

Fig 2 Preoperative systolic and diastolic pulmonary artery pressures (PAP) of group II (n = 21) were higher than those of group I (n = 29). Postoperative systolic pulmonary artery pressures of groups I and II significantly decreased in comparison with preoperative data (paired t test), and were reversible to almost normal values 1 month after operation. The postoperative diastolic pulmonary artery pressure of group II significantly decreased in comparison with preoperative value, and was reversible to almost normal value.
