Background: Bronchial artery revascularization (BAR) during lung transplantation has been hypothesized to improve early tracheal healing and delay the onset of bronchiolitis obliterans syndrome (BOS). We aimed to assess the outcomes of BAR after lung transplantation., Methods: Electronic search in Ovid Medline, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Scopus, and Cochrane Controlled Trials Register (CCTR) databases was performed to identify all relevant studies published about lung transplantation with BAR. Studies discussing lung transplantation utilizing BAR were included while those without outcome data such as BOS and survival were excluded. Cohort-level data were extracted and pooled for analysis. A binary outcome meta-analysis of proportions with logit transformation was conducted. Newcastle-Ottawa scale was used for risk of bias assessment., Results: Seven studies were selected for the analysis comprising 143 patients. Mean patient age was 47 (95% CI: 40-55) years. Sixty-one percent (48-72%) were male. Seventy-three percent (65-79%) of patients underwent double lung transplant while 27% (21-25%) underwent single lung transplant. In patients with postoperative angiography, successful BAR was demonstrated in 93% (82-97%) of all assessed conduits. The 30-day/in-hospital mortality was 6% (3-11%). Seventy-nine percent (63-89%) of patients were free from rejection at three months. Eighty-three percent (29-98%) of patients were free from signs of airway ischemia at three and six months. Pooled survival at one year and five years was 87% (78-92%) and 71% (46-87%), respectively, with a mean follow-up time of 21 (3-38) months. Pooled freedom from bronchiolitis obliterans was 86% (77-91%) at two years., Conclusions: While this systematic review and meta-analysis is limited by the available surgeons, institutions, and papers discussing a highly specialized technique, it does show that BAR is a viable technique to minimize BOS and early anastomotic intervention following lung transplantation., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-22-213/coif).

Functional tricuspid regurgitation (TR) is primarily caused by enlargement of the tricuspid annulus due to right ventricular dilation, frequently secondary to left sided valvular disease. Early techniques for the treatment of functional TR were introduced by Jerome Kay in 1965 and Norberto DeVega in 1972. Modified suture annuloplasty is a modification of DeVega's semicircular purse string technique, however, it is based on Kay's principle of obliteration of the posterior segment of the annulus only. While ring annuloplasty is the procedure of choice for severe functional TR, posterior suture annuloplasty is a technically simpler option for patients with moderate functional TR., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

The first successful mitral valve repair was performed by Elliot Cutler at Brigham and Women's Hospital in 1923. Subsequent evolution in the surgical techniques as well as multi-disciplinary cooperation between cardiac surgeons, cardiologists and cardiac anesthesiologists has resulted in excellent outcomes. In spite of this, the etiology of mitral valve pathology ultimately determines the outcome of mitral valve repair.
