RESUMO

BACKGROUND: Previous studies have established that moderately to severely calcified lesions (MSCL) are associated with high rates of major adverse cardiovascular events, even when drug-eluting stents are implanted after rotational atherectomy (RA). Yet, the changes in coronary function indexes during follow-ups have never been investigated. The quantitative flow ratio (QFR), a novel coronary function index, has been increasingly adopted in daily practice in recent years. METHODS: A total of 111 MSCL patients were retrospectively enrolled in this study. The vessel QFR (QFRv) loss was defined as post-percutaneous coronary intervention QFRv minus follow-up QFRv. The study subjects were divided into high QFRv loss (n = 51) and low QFRv loss (n = 60) groups according to the binary method. The obtained predictors of QFRv loss were then analyzed. RESULTS: The results showed that the final burr-to-vessel ratio (B to V ratio) in the high QFRv loss group decreased significantly compared to the low QFRv loss group (p < 0.01). The univariate and multivariate regression analyses indicated that the final B to V ratio was an excellent predictor of QFRv loss. The cut-off value of the final B to V ratio for QFRv loss prediction was 0.50 (sensitivity: 50.98%, specificity: 68.33%, and area under the curve: 0.627 [95% confidence interval: 0.530-0.717], p < 0.05). Additionally, the target vessel failure incidence in the high QFRv loss group was higher than in the low QFRv loss group (p < 0.01). CONCLUSIONS: An increased burr-to-vessel ratio can prevent QFRv loss in patients with MSCLs after RA, an effect that might be closely associated with a low target vessel failure incidence.

RESUMO

OBJECTIVE: To repair the complete cleft palate with the most popular technique at optimal time. METHODS: Bilateral unipedicle flaps (Bardach method) combined with levator sling plasty were employed to repair complete cleft palate at the age of 6 - 12 months. Computer-aided FFT vocal analysis was performed before and after surgery. RESULTS: All patients had primary wound healing without any complication. The FFT vocal analysis showed great improvement in velopharyngeal incompetence after surgery. CONCLUSIONS: It is technically safe and feasible to repair the complete cleft palate at the age of 6 - 12 months with bilateral unipedicle flaps. Encouraging speech improvement can be expected with this method.
