Clinical outcomes and 1-year Follow-Up.
Clinical outcomes at 30 days and 1-year follow-up are shown in Table 4. No patient was missing in the present study. The 30-day all-cause mortality rate was 2.9%, and no major stroke occurred in any patient. In these patients, 1-year all-cause mortality was 7.4% (Figure 5). Landmark analysis demonstrated that the most mortality occurred after 30 days of the procedure (Figure 6). Three patients had a stroke, resulting in a 1-year stroke rate of 2.2%, where two patients died. One patient had a type-A aortic dissection at six months follow-up, while one patient underwent reoperation due to prosthetic valve thrombosis at seven months postoperatively, although the latter refused further surgical treatment. New PPMI was required in twelve patients (8.9%).
