Mid-term results of ATS open pivot bileaflet mechanical prosthetic heart valve


, : Mid-term results of ATS open pivot bileaflet mechanical prosthetic heart valve. Annals of Thoracic and Cardiovascular Surgery 6(1): 34-38

We investigated mid-term results of the patients with an ATS bileaflet valve in our institution. In the past 6 years, 69 patients received valve replacement with an ATS valve. We assessed the changes of serum lactate dehydrogenase (LDH) level in the hospital, and the valve's closing sound. The serum LDH level had almost normalized one week postoperatively and they have maintained normal levels since then. According to the questionnaire about the valvular sound at a random period after surgery, it was unnoticeable in 61 (88.4%) of the patients with ATS valve. In the 8 patients (12.6%) who recognized the valve sound, 7 of them were reoperation cases. As to the frequency analysis for the valve's closing sound, the sound peak was indicated at around 1.2 kHz in the patients with ATS valves. In patients with St. Jude Medical (SJM) valves, it appeared not only around 1.2 kHz but also around 2 to 7 kHz. Postoperative cerebral infarction was complicated in one patient. Mortality occurred in 4 (5.7%) of the patients with ATS valves. The follow up periods were from one to 66 months. Thromboembolic event free and actuarial survival rate in the patients with ATS valves were 98.6% and 94.2%, respectively. These results indicated that the ATS valve is considered to be a safe valve and mid-term follow-up shows excellent results in terms of the patients quality of life.
