Recently, the Tricuspid Valve Academic Research Consortium (TVARC) released its first document, a consensus statement aimed at bridging the current knowledge gaps in the study of tricuspid regurgitation (TR). The current classification of TR is not uniform, and as such it is challenging to stratify and study disease outcomes, especially in a growing field where transcatheter alternates to surgery are also being studied. This first document by the consortium aims to address these knowledge gaps and standardize the terminology and gives general endpoints for trials to allow for better study of the disease and promote research. The authors report that a second paper is underway, which will go into more granular detail to characterize this disease even further.Recently, the Tricuspid Valve Academic Research Consortium (TVARC) released its first document, a consensus statement aimed at bridging the current knowledge gaps in the study of tricuspid regurgitation (TR).

The authors of this study conducted a systematic review of clinical outcomes after pediatric aortic valve repair (AVr) and examined life expectancy and risk of reintervention using microsimulation. The study included forty-one publications including 2,636 patients with 17,217 years of follow-up (median follow up was 7.3. years). Pooled early mortality rates after AVr in children (<18 years), infants (<1 year), and neonates (<30 days) were, respectively, 3.5 percent, 7.4 percent, and 10.7 percent. The pooled late reintervention rates in children, infants and neonates were 3.3 percent per year, 6.8 percent per year, and 6.32 percent per year. Microsimulation-based mean life expectancy in the first twenty years was 18.4 years. Despite a high hazard of reintervention for valve dysfunction and slightly impaired survival compared with the general population, AVr has low valve-related event occurrences and should always be considered.

Patients younger than nineteen years old were included in a study developed to gain a better understanding of pediatric patients supported with ventricular assist devices (VADs). The authors found that illness at VAD implantation, diagnosis, and strategy of support affect survival and differ by device type. The study can act as a predictive tool to help providers make informed decisions.

This paper looks to explore the outcomes in obese patients with non-small cell lung cancer following VATS or open lobectomy. The authors utilized data from the European Society of Thoracic Surgeons Database to assess morbidity and postoperative length of stay in 78,018 patients across a fourteen-year period. An intention-to-treat analysis was used, with assessment performed using univariable, multivariable-adjusted, and propensity-score-matched analyses. VATS lobectomy was found to be associated with improved postoperative outcomes.

ECMOSARS registry data was used to describe the characteristics and outcomes of COVID-19 patients undergoing either veno-arterial (VA) or veno-arterial venous (VAV) extracorporeal membrane oxygenation (ECMO). The authors concentrated on forty-seven patients, with a median age of forty-nine years, supported with VA or VAV-ECMO for refractory cardiogenic shock. Fourteen percent had a previous heart failure diagnosis. The two most common causes of cardiogenic shock were acute pulmonary embolism (30 percent) and myocarditis (28 percent). Thirty-eight percent of the patients underwent extracorporeal cardiopulmonary resuscitation (eCPR). In-hospital survival in the whole group was 28 percent (43 percent if eCPR patients were excluded). One day after ECMO cannulation, nonsurvivors had significantly more severe acidosis and higher FiO2. Several other factors were associated with death.
 
The authors concluded that VA-ECMO is a viable rescue therapy in carefully selected patients and suggested that eCPR is not a reasonable indication for ECMO in this group.

A number of interesting points are raised in this relatively short manuscript. The authors conclude that there is an unmet need for robust independent international registry data from the manufacturers so that stakeholders can have informed choices on the performance of stent grafts. Perhaps most importantly, the authors conclude that the failed stent grafts had indications of failure in the completion angiogram, and it is not clear if action was taken.

This paper looked at the immunotherapy agent Durvalumab used in the perioperative period for resectable NSCLC. A total of 802 patients were enrolled in the study, of which 400 received Durvalumab and the remaining 402 a placebo. The two primary endpoints measured were event-free survival and pathological complete resection. Perioperative Durvalumab plus neoadjuvant chemotherapy, as compared with neoadjuvant chemotherapy alone, was significantly associated with improved results in the two primary endpoints measured. Event-free survival was longer with Durvalumab. The stratified hazard ratio for disease progression, recurrence, or death was 0.68 (p=0.004.) At twelve months, event-free survival was observed with 73.4 percent of Durvalumab patients compared to 64.5 percent of placebo patients. The incidence of pathological complete response was significantly greater with Durvalumab then with placebo (17.2 percent and 4.3 percent respectively, p <0.001). Moreover, a benefit was seen regardless of PD-L1 expression and stage.

In this meta‐analysis, the authors performed a pooled analysis of time‐to‐event data from Kaplan-Meier curves of randomized controlled trials (RCTs) and propensity‐score matched (PSM) studies comparing transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in low-risk patients. The meta-analysis aimed to assess the midterm outcomes of both treatment strategies in low-risk patients. A total of eight studies (three RCTs, five PSM studies) published by December 31, 2022 met the eligibility criteria and included 5,444 patients. 2,639 patients underwent TAVR and 2,805 patients underwent SAVR. In low‐risk patients, TAVR showed a higher risk of all‐cause mortality at eight years of follow up. SAVR was associated with improved survival beyond two years. The survival benefit of SAVR was driven by PSM studies and could not be observed in RCTs. The addition of more extended follow up data from ongoing RCTs will help confirm the possible difference in mid and long term survival between TAVR and SAVR in the low‐risk population.

An official press release from the University of Maryland School of Medicine announced the passing of Mr. Lawrence Faucette, the patient with terminal heart failure who received the world’s second genetically modified pig heart transplant. Mr. Faucette lived for nearly six weeks following the surgery and ultimately succumbed on October 30 due to acute organ rejection despite the initial early success and significant progress after surgery. The medical and scientist team in charge of the xenotransplantation program will conduct an extensive analysis to identify factors that can help to improve the outcome in future xenotransplantation.

The clinical problem addressed in this study is bleeding in patients who undergo ECMO. The authors endeavor to address the issue through a quantitative cohort study by reflecting on how to target the behavior of platelets.
