RESUMO
Objective: Studies have shown that requiring tracheostomy following cardiac surgery has significant implications on outcomes. This study proposes a risk stratification model to predict the likelihood of requiring a tracheostomy after cardiac surgery. Methods: Patients who underwent cardiac surgery between January 2010 and December 2019 were analyzed. Kaplan-Meier analysis and log-rank test were used to estimate and compare survival between cohorts. A prediction model for the need for postoperative tracheostomy was developed with logistic regression combined with undersampling analysis. Results: A total of 9849 patients underwent cardiac surgery, and 176 (1.8%) required postoperative tracheostomy. Tracheostomy patients were older (mean age 68.4 ± 12.3 vs 65.9 ± 11.2 years; P < 0.01) and more likely female (43.8% vs 28.5%; P < 0.01). Predictors for requiring tracheostomy included hypertension (odds ratio [OR] 1.91; P = 0.05), New York Heart Association III/IV (OR 2.68; P < 0.001), chronic lung disease (OR 3.27; P < 0.001), and history of prior myocardial infarction (OR 3.32; P < 0.001). Three-year Kaplan-Meier survival was worse in patients who received tracheostomy (log-rank P < 0.001). Conclusions: A risk prediction model for requiring tracheostomy after cardiac surgery is proposed in this study. A history of New York Heart Association III/IV, chronic lung disease, and myocardial infarction as well as undergoing valve surgeries were associated with increased risk of requiring a tracheostomy.
RESUMO
BACKGROUND: The Ross procedure is not commonly performed, owing to the procedural complexity and the risk of autograft and/or homograft reoperation. This study examined outcomes of patients undergoing Ross reinterventions at a dedicated Ross center. METHODS: We retrospectively reviewed 225 consecutive patients who underwent a Ross procedure between 1994 and 2019. Index and redo operation characteristics and outcomes were compared between patients with and those without redo operations. Multivariate analysis was used to identify independent predictors of Ross-related reinterventions. Survival was estimated with Kaplan-Meier analysis. RESULTS: Sixty-six patients (29.3%) required redo Ross surgery, 41 patients (18.2%) underwent autograft reoperation only, 8 patients (3.6%) had a homograft reintervention, and 17 patients (7.6%) had both autograft and homograft reoperations (12 as a combined procedure and 5 as sequential procedures). The mean time to reintervention was 11 ± 6 years for autograft reoperations and 12 ± 7 years for homograft reoperations. Patients who underwent Ross-related reinterventions were younger (mean, 38 ± 11 years vs 43 ± 11 years; P < .01) and had a higher rate of New York Heart Association class III/IV (56% vs 38%; P = .02) at the index Ross procedure. Most patients undergoing autograft reintervention had aortic insufficiency and/or aneurysm (98.2%; 57 of 58). The primary reason for homograft reintervention was pulmonary stenosis (92%; 23 of 25). The operative mortality of Ross reintervention was 1.5% (1 of 66). Survival at 15 years was similar in patients who required a redo operation and those who did not (91.2% vs 93.9%; P = .23). CONCLUSIONS: Ross reinterventions can be performed safely and maintain patients at the normal life expectancy restored by the index Ross procedure up to 15 years at experienced centers.

OBJECTIVES: Aortic root enlargement (ARE) lowers the risk of patient prosthesis mismatch after surgical aortic valve replacement (SAVR) in patients with small annular size. Whether ARE is associated with increased operative mortality is controversial. This study compares the early and intermediate outcomes in patients undergoing SAVR with and without ARE. METHODS: All patients undergoing isolated SAVR with and without ARE from 2015 to 2020 were analyzed. Propensity-matching was used to adjust for possible confounding variables. Kaplan-Meier analysis and log-rank test were used to estimate and compare overall outcomes and survival in the study cohorts. RESULTS: Among 868 isolated SAVRs, ARE was performed in 54 (6.2%) patients. Before matching, mean age was similar but female sex (67.4% vs. 29.6%; SD: -0.82) and previous AVR (18.9% vs. 3.9%; SD: -0.48) were more common in patients undergoing SAVR + ARE versus SAVR alone. A bovine pericardial patch was used for 81.5% (44 of 54) of ARE, with a Dacron patch in the rest. After propensity matching, the average cardiopulmonary bypass (138.2 ± 34.9 vs. 102.9 ± 33.0 min; p < 0.01) and cross-clamp times (113.8 ± 26.7 vs. 83.0 ± 28.4 min; p < 0.01) were longer in the SAVR + ARE group. There were no significant differences in postoperative stroke, new-onset dialysis, pacemaker placement, reoperation for bleeding, length of hospital stay, or 30-day readmission. Thirty-day mortality (0% vs. 0.6%, p = 1.0) and 5-year survival (96.3% vs. 95.7%, p = 0.86) were also similar. CONCLUSIONS: ARE during surgical AVR can be safely performed without an increase in complications with excellent early and intermediate-term survival.

BACKGROUND: Adaptive mutations of the severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) virus have emerged throughout the coronavirus disease 2019 (COVID-19) pandemic. The characterization of outcomes in patients requiring extracorporeal membrane oxygenation (ECMO) for severe respiratory distress from COVID-19 during the peak prevalence of different variants is not well known. METHODS: There were 131 patients with laboratory-confirmed SARS-CoV-2 infection supported by ECMO at two referral centers within a large healthcare system. Three predominant variant phase time windows (Pre-Alpha, Alpha, and Delta) were determined by a change-point analyzer based on random population sampling and viral genome sequencing. Patient demographics and outcomes were compared. RESULTS: The average age of patients was 46.9 ± 10.5 years and 70.2% (92/131) were male. Patients cannulated for ECMO during the Delta variant wave were younger compared to earlier Pre-Alpha (39.3 ± 7.8 vs. 48.0 ± 11.1 years) and Alpha phases (39.3 ± 7.8 vs. 47.2 ± 7.7 years) (p < .01). The predominantly affected race in the Pre-Alpha phase was Hispanic (52.2%; 47/90), while in Alpha (61.5%; 16/26) and Delta (40%; 6/15) variant waves, most patients were White (p < .01). Most patients received a tracheostomy (82.4%; 108/131) with a trend toward early intervention in later phases compared to Pre-Alpha (p < .01). There was no significant difference between the duration of ECMO, mechanical support, intensive care unit (ICU) length of stay (LOS), or hospital LOS over the three variant phases. The in-hospital mortality was overall 41.5% (54/131) and was also similar. Six-month survival of patients who survived to discharge was 92.2% (71/77). CONCLUSIONS: There was no significant difference in survival or time on ECMO support in patients during the peak prevalence of the three variants.
