Abstract
This study aimed to show the outcomes of isolated tricuspid valve replacement (ITVR) after left-sided valve surgery (LSVS). Patients who underwent ITVR after LSVS were divided into bioprosthetic tricuspid valve (BTV) and mechanical tricuspid valve (MTV) groups. Clinical data were collected and analyzed between groups. 101 patients were divided into BTV (n = 46) and MTV (n = 55) groups. The mean ages of the BTV and MTV groups were 63.4 ± 8.9 and 52.4 ± 7.6 years, respectively (P <0.01). There was no significant difference in 30-day mortality (BTV 10.9% vs. MTV 5.5%), early postoperative complications, and long-term tricuspid valve (TV)-related adverse events between these two groups. New-onset renal insufficiency was an independent risk factor for early mortality. Survival rates in the BTV group were 94.8% ± 3.6%, 86.5% ± 6.5%, and 54.2% ± 17.6% and in the MTV group were 96.0% ± 2.8%, 79.0% ± 7.4%, and 59.4% ± 14.8% at 1, 5, and 10 years, respectively (P = 0.826). The TV prosthesis selection in ITVR after LSVS seems to not affect 30-day mortality and early postoperative complications. Long-term survival and the occurrence of TV-related events were also comparable between these two groups.
