Transfemoral versus transcarotid access for transcatheter aortic valve replacement.

Objectives: To compare the outcomes after transcatheter aortic valve replacement (TAVR) through a transfemoral (TF) and transcarotid (TC) access at our institution. Methods: From January 2014 to January 2020, 62 TC-TAVR and 449 TF-TAVR were performed using 2 prosthesis devices (Edwards SAPIEN 3, n = 369; Medtronic Evolut R, n = 142). Propensity score matching was used to adjust for imbalance in the baseline characteristics of the study groups. Results: Propensity score matching provided 62 matched pairs with comparable operative risk (mean European System for Cardiac Operative Risk Evaluation II, TC-TAVR 7.6% vs TF-TAVR 6.6%, P = .17). Thirty-day mortality (4.8% vs 3.2%, P = 1.00) and 2-year mortality (11.3% vs 12.9%, P = .64) after TC-TAVR were comparable with TF-TAVR. Strokes were numerically more frequent after TC-TAVR compared with TF-TAVR (3.2% vs 0%, P = .23), but the difference did not reach statistical significance. TF-TAVR was associated with a significantly greater risk of permanent pacemaker implantation (29.0% vs 12.9%, P = .04) compared with TC-TAVR. Other complications were not frequent and were similarly distributed between the matched groups. Conclusions: TC access for TAVR was associated with satisfactory results compared to the femoral access. TC-TAVR could be considered a valid and safe alternative to TF-TAVR when femoral access is contraindicated.

Negative Pressure versus Conventional Sternal Wound Dressing in Coronary Surgery Using Bilateral Internal Mammary Artery Grafts.

BACKGROUND: Sternal wound infection (SWI) is a major complication occurring often after coronary artery bypass grafting (CABG) using bilateral internal mammary artery (BIMA) grafts. The aim of this study is to assess whether such a risk may be reduced by using incision negative pressure wound therapy (INPWT). METHODS: Data on patients undergoing isolated CABG using BIMA grafts at the Reims University Hospital, France, from 2013 to 2016 without or with INPWT was prospectively collected.  Results: INPWT was used in 161 patients and conventional sterile wound dressing was used in 266 patients. Propensity score matching resulted in 128 pairs with similar characteristics. SWIs were similarly distributed between the conventional sterile wound dressing (10.9%) and the INPWT cohorts (10.2%) (P = 1.00). Patients treated with INPWT had a lower rate of deep SWI/mediastinitis than patients who had conventional sterile dressing (5.5% versus 10.2%, P = .210), but the difference did not reach statistical significance. Tests for interaction confirmed these findings in different patient subgroups. CONCLUSION: The routine use of INPWT may not significantly reduce the risk of SWI in patients undergoing BIMA grafting. In view of previous reports showing a benefit with the use of this method, a large randomized study is justified to assess the efficacy of INPWT in patients undergoing cardiac surgery.
