“…In addition, the 5-year survival that we observed for each valve seems to be similar to the one observed by others 15,18 . Chronic anticoagulation remains the main cause of valve-related events in patients with mechanical prostheses.…”

“…Chronic anticoagulation remains the main cause of valve-related events in patients with mechanical prostheses. The percentage of patients free of thromboembolic events was higher in the AVR cohort than in the MVR cohort, similarly to what was observed by others 18 . However, the linearized rate of thromboembolic complications in this series is comparable with other series of St Jude medical, as well as the incidence of anticoagulationrelated bleeding complications 15,[17][18][19] .…”

The higher incidence of thromboembolic events in patients with mitral mechanical prosthesis is a well known fact 1 , in which atrial fibrillation certainly also has a important role.…”

“…Long term survival following mechanical AVR is 59%±2% at 10 years [9]. In a long-term study of patients undergoing mAVR, the linear zed rates per 100 patients years of follow-up were embolism 0.25, paravalvular leakage 0.25, prosthetic endocarditic 0.25 and reoperation 0.50 [10].…”

“…20 In contrast, the incidence of transient ischemic attacks was lower than in other studies. 11, 13 Because we could not follow up all the patients every month or even every year after surgery, some non-fatal incidents, including transient ischemic attacks, may have been missed during the follow-up period. No structural valve deterioration was observed during the 30-year study period after AVR.…”

In particular, the differences in the rates of thromboembolic and hemorrhagic complications in various age groups of patients implanted with SJM valves are not currently well described in the literature. We herein analyzed >25 years of clinical experience with SJM valves in order to evaluate the reliability of these secondgeneration bi-leaflet valves in Japanese patients, based on prosthesis model and patient age. MethodsThis study involved human subjects and was reviewed and approved by the Institutional Review Board at Kyushu University. Two hundred and sixty-six patients underwent AVR with SJM prostheses between November 1981 and December 2014. Among these patients, 26 patients who underwent aortic root replacement (Bentall operation) were excluded to ensure simplicity of analysis. Therefore, a total of 240 patients implanted with aortic SJM prostheses were included in this study. We divided all patients into 2 groups: younger (<65 years old, n=157) and older (≥65 years old, n=83; Table 1). Mean he use of bioprostheses has been increasing along with improvements in durability, 1-4 but mechanical valves continue to be useful prostheses, especially for younger patients, due to their excellent long-term durability and low risk of reoperation. Both in vitro and in vivo data indicate excellent hemodynamic performance associated with a low incidence of valve-related morbidity for St. Jude Medical (SJM; Minneapolis, MN, USA) mechanical prostheses. Therefore, at Kyushu University Hospital we have used 3 serial types of SJM bileaflet mechanical heart valve for aortic valve replacement (AVR) since 1981.The sewing ring in the original SJM standard (ST) model was modified, without changing the pivotal design or bloodcontact surface area, to produce the Hemodynamic Plus (HP) model, in which the bulk of the sewing ring has been reduced. The latest Regent (RE) model has a modified external profile that achieves a larger geometric orifice area. This modification allows for the implantation of a larger device, approximately 1.5 sizes larger than the original ST model.Although SJM mechanical prostheses implanted in relatively younger patients are, in general, expected to be reliable and durable, without the need for additional surgery in the long term (>25 years after surgery), anti-coagulation-related complica- T
