Bauser-Heaton and colleagues evaluated outcomes for patients with complex tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs), focusing on those patients who underwent unifocalization with placement of a shut rather than simultaneous intracardiac repair. Between 2001 and 2017, 57 patients underwent this type of procedure at the authors’ center. In this high-risk cohort, complete repair was achieved in 67% of patients within 3 years. The median right ventricle to systemic pressure ratio for patients with complete repair was 0.4.

Ng and colleagues reviewed articles published between 2000 and 2018 to compare lobectomy approaches of multiport, uniportal, and robotic video-assisted thoracic surgery (VATS) and open lobectomy, with the aim of providing evidence-based recommendations for the optimal surgical approach for early stage non­–small cell lung cancer. One hundred and forty-five studies were included in the meta-analysis, which supported the usage of VATS approaches for lobectomy. Multiport VATS was found to have a lower rate of adverse events and less pain than open lobectomy. The different VATS approaches were similar to each other for most outcomes, with uniportal VATS potentially being associated with less pain.

This keynote lecture highlights the need for a standardized prepump intraoperative echocardiology protocol in order to provide a surgeon and their team with a roadmap as to what techniques may be applied for an effective repair of the aortic valve. The authors conclude that such a protocol is essential in enhancing the heart team’s approach by providing a common language between surgeons and echocardiologists, which they hope will ultimately increase aortic valve repairs for select patients in expert centers.

Thoracic stentgrafts are stiffer than the aorta. To understand how this mismatch might affect the left ventricle, van Bakel and colleagues quantified the left ventricular remodeling after thoracic endovascular aortic repair (TEVAR) in 8 patients. They estimated an increase in left ventricular stroke work and found an increase in left ventricular mass after TEVAR. The authors conclude that compliant endografts should be developed to prevent adverse left ventricular remodeling after TEVAR.

Holm and colleagues evaluated perioperative bleeding after coronary artery bypass grafting (CABG) in patients who were taking P2Y12 inhibitors. Patient outcomes from the European Multicenter Registry on Coronary Artery Bypass Grafting were included in the analysis, with 1,293 patients who received clopidogrel preoperatively and 1,018 who received ticagrelor. The authors observed a higher incidence of major bleeding in patients when these therapies were discontinued for fewer days prior to CABG, and they suggest postponing nonemergent procedures for at least 3 and 4 days after discontinuation of ticagrelor and clopidogrel, respectively.

Rodríguez-Caulo and colleagues report a retrospective multicenter study on almost 1,500 patients aged 50-65 who underwent aortic valve replacement with mechanical or biological prosthesis. The mean length of follow-up was 8 years. There was no significant difference in survival between the valve types. There was a higher rate of major bleeding in patients with mechanical prosthesis; however, reoperation was more frequent among those with a biological prosthesis. The authors conclude that a bioprosthesis in patients of age 55 years and older is a reasonable choice.

Research, Trials, and Funding

Researchers from Vanderbilt University in Tennessee, USA, report that among adults diagnosed with lung cancer, a smaller proportion of black Americans than white Americans would have qualified for screening.

In this systematic review, Arnaoutakis and colleagues evaluated the repair durability and survival of patients who underwent repair for a bicuspid aortic valve (BAV). Twenty-six studies were evaluated after full exclusion criteria were applied. BAV repair was demonstrated to have low operative mortality and excellent 5-year survival. Variations in surgical technique (eg, in reimplantation or remodeling), were not associated with protection from reintervention. Systematic assessment of cusp height and annular stabilization favored long-term durability, and increased leaflet calcification was noted to have higher rates of reintervention.

Social media offers enormous potential benefits for both care providers and patients, because the platform allows for the dissemination and gathering of information and has the innate ability to network globally. The Cardiothoracic (CT) Ethics Forum functions as the ethics educational arm for the CT surgical community, producing ethics-related programs at major CT surgery meetings and subsequently publishing articles on those proceedings as well as ethical topics in CT surgical and other medical specialty journals. The Forum has constructed a very important and useful set of recommendations for CT surgeons as they engage with social media.
