Deep Sternal Wound Infection and Mortality in Cardiac Surgery: A Meta-analysis

BackgroundDeep sternal wound infection (DSWI) is a rare but severe complication after cardiac surgical procedures and has been associated with increased early morbidity and mortality. Studies reporting long-term outcomes in patients with DSWI have shown contradictory results. We performed a study-level meta-analysis evaluating the impact of DSWI on short- and long-term clinical outcomes.MethodsA systematic literature search was conducted to identify studies comparing short- and long-term outcomes of patients submitted to cardiac surgical procedures who developed DSWI and patients who did not. The primary outcome was overall mortality. Secondary outcomes were in-hospital mortality, follow-up mortality, major adverse cardiovascular events, myocardial infarction, and repeat revascularization. Postoperative outcomes were also investigated.ResultsTwenty-four studies totaling 407 829 patients were included. Overall, 6437 (1.6%) patients developed DSWI. Mean follow-up was 3.5 years. DSWI was associated with higher overall mortality (incidence rate ratio [IRR], 1.99; 95% CI, 1.66-2.38; P < .001), in-hospital mortality (odds ratio, 3.30; 95% CI, 1.88-5.81; P < .001), follow-up mortality (IRR, 2.02; 95% CI, 1.39-2.94; P = .001), and major adverse cardiovascular events (IRR, 2.04; 95% CI, 1.60-2.59; P < .001). No differences in myocardial infarction and repeat revascularization were found, but limited studies reported those outcomes. DSWI was associated with longer postoperative hospitalization, stroke, myocardial infarction, and respiratory and renal failure. Sensitivity analyses on isolated coronary artery bypass grafting studies and by adjustment method were consistent with the main analysis.ConclusionsCompared with patients who did not develop DSWI, patients with DSWI after cardiac surgical procedures had increased risk of death as well as short- and long-term adverse clinical outcomes.     

Surgery for laryngotracheal stenosis: Improved results

ObjectiveLaryngotracheal resection is still considered a challenging operation and few high-volume institutions have reported large series of patients in this setting. During the 5 years, novel surgical techniques as well as new trends in the intra- and postoperative management have been proposed. We present results of our increased experience with laryngotracheal resection for benign stenosis.MethodsBetween 1991 and May 2019, 228 consecutive patients underwent laryngotracheal resection for subglottic stenosis. One hundred eighty-three (80.3%) were postintubation, and 45 (19.7%) were idiopathic. Most of them (58.7%) underwent surgery during the past 5 years. At the time of surgery, 139 patients (61%) had received tracheostomy, laser, or laser plus stenting. The upper limit of the stenosis ranged between actual involvement of the vocal cords to 1.5 cm from the glottis.ResultsThere was no perioperative mortality. Two hundred twenty-two patients underwent resection and anastomosis according to the Pearson technique; 6 patients with involvement of thyroid cartilage underwent resection and reconstruction with the laryngofissure technique. Airway resection length ranged between 1.5 and 8 cm (mean, 3.8 ± 0.8 cm) and it was >4.5 cm in 19 patients. Airway complication rate was 7.8%. Overall success of airway complication treatment was 83.3%. Definitive success was achieved in 98.7% of patients. Patients presenting with idiopathic stenosis or postcoma patients showed no increased failure rate.ConclusionsLaryngotracheal resection for benign subglottic stenosis is safe and effective, and provides a very high rate of success. Careful intra- and postoperative management is crucial for a successful outcome.     

Endoscopic vs Open Vein Harvest in Drug-Eluting Stents or Bypass Surgery for Left Main Disease Trial

BackgroundWe investigated outcomes of coronary artery bypass grafting (CABG) with endoscopic vein harvest (EVH) vs open vein harvest (OVH) within the Evaluation of XIENCE Versus CABG (EXCEL) trial.MethodsAll patients in EXCEL randomized to CABG were included in this study. For this analysis, the primary end points were ischemia-driven revascularization (IDR) and graft stenosis or occlusion at 5 years. Additional end points were as follows: a composite of death from any cause, stroke, or myocardial infarction; bleeding; blood product transfusion; major arrhythmia; and infection requiring antibiotics. Event rates were based on Kaplan-Meier estimates in time-to-first-event analyses.ResultsOf the 957 patients randomized to CABG, 686 (71.7%) received at least 1 venous graft with 257 (37.5%) patients in the EVH group and 429 (62.5%) patients in the OVH group. At 5 years, IDR was higher (11.5% vs 6.7%; P = .047) in the EVH group. At 5 years, rates of graft stenosis or occlusion (9.7% vs 5.4%; P = .054) and the primary end point (17.4% vs 20.9%; P = .27) were similar. In-hospital bleeding (11.3% vs 13.8%; P = .35), in-hospital blood product transfusion (12.8% vs 13.1%; P = .94), and infection requiring antibiotics within 1 month (13.6% vs 16.8%; P = .27) were similar between EVH and OVH patients. Major arrhythmia in the hospital (19.8% vs 13.5%; P = .03) and within 1 month (21.8% vs 15.4%; P = .03) was higher in EVH patients.ConclusionsIDR at 5 years was higher in the EVH group. EVH and OVH patients had similar rates of graft stenosis or occlusion and the composite of death, stroke, or myocardial infarction at 5 years.     

Evolution of Pulmonary Valve Management During Repair of Tetralogy of Fallot: A 14-year Experience

BackgroundThe optimal repair strategy for tetralogy of Fallot remains controversial. This report presents a 14-year evolution of management of the pulmonary valve (PV) from transannular patch to valve-sparing repair to neovalve creation using living right atrial appendage tissue.MethodsA retrospective review of 172 consecutive patients undergoing complete repair for TOF between January 2007 and June 2021 was performed. Clinical and follow-up data were analyzed by repair group. Neopulmonary valve (NPV) creation using right atrial appendage tissue was introduced in 2019. Failure of valve-sparing repair was defined as needing reintervention for recurrent right ventricular outflow tract obstruction (RVOTO).ResultsMedian age and weight at repair were 4.9 months and 6 kg, respectively. Median preoperative PV size and z-score were 6.4 mm (5.2-8.3 mm) and ?3.2 (?4.1 to ?2.1), respectively. Patients who underwent valve-sparing repair had larger PV size and z-score compared with patients who underwent transannular patch procedures (8 mm vs 5.6 mm; ?2.1 vs ?3.2; both P < .001). There were no hospital mortalities. Overall follow-up was 44 months. At last follow-up, 10% of patients who underwent valve-sparing repair had repeat intervention for recurrent RVOTO. Patients who had failed valve-sparing repair had significantly lower PV z-scores (?2.6 vs ?1.9; P = .01). An NPV was used in 8 patients with a median PV z-score of ?4 (?4.7 to ?3.9). At 6 months, 6 patients (75%) had mild or trivial pulmonary insufficiency after NPV placement.ConclusionsRepair of tetralogy of Fallot is a safe operation with excellent outcomes. Valve-sparing repair avoids right ventricular dilation but may fail for RVOTO at a PV z-score <?2. NPV creation offers an alternative option in patients with a small PV.

Risk of Surgical Mitral Valve Repair for Primary Mitral Regurgitation

BackgroundRisk estimation for surgical intervention is an essential component of heart team shared decision-making. However, current mitral valve (MV) surgery risk models used in practice lack etiologic or procedural specificity. The purpose of this study was to establish a comprehensive method for assessment of operative risk of MV repair of primary mitral regurgitation (MR).MethodsA novel etiology and procedure-specific algorithm identified 53,462 consecutive (July 2014 to June 2020) intention-to-treat MV repair patients with primary MR from The Society of Thoracic Surgeons Adult Cardiac Surgery Database. Risk models were fit for 30-day operative mortality, mortality and/or major morbidity, and conversion-to-replacement (CONV). As-treated mortality and morbidity models were derived separately.ResultsEvent rates for mortality (n = 619; 1.16%), mortality plus morbidity (n = 4746; 8.88%), and CONV (n = 3399; 6.36%) were low. Mortality was higher in CONV patients vs repair (3.18% vs 1.02%). All event rates were lower with increasing program volumes. The mortality risk model had excellent discrimination (AUC: 0.807) and calibration and confirmed very low mortality risk for isolated MV repair for primary MR, with mean mortality risk of 1.16% and median of 0.55% (interquartile range: 0.30%-1.17%) with 90th and 95th percentiles 2.48% and 3.99%, respectively. The mortality risk was <0.5% in patients <65 years of age, with 97% of the total population across age groups having a risk of <3%. Only 1 in 4 patients age 75 or older had >3% estimated risk of mortality.ConclusionsThis etiologic and procedure-specific risk model establishes that the contemporary mortality risk of MV repair for primary MR is <1% for the vast majority of patients.

Improved Outcomes of Reimplantation vs Remodeling in Marfan Syndrome: A Propensity-Matched Study

BackgroundValve-sparing root replacement (VSRR) has excellent outcomes when performed in experienced centers in well-selected patients. It is suggested that reimplantation of the aortic valve may have better durability than remodeling in patients with Marfan syndrome (MFS), although long-term comparative data are limited.MethodsBetween 1988 and 2018, 194 patients with MFS underwent VSRR at our institution. From these, we derived a propensity-matched cohort of 68 patients (44 who underwent reimplantation and 24 who had remodeling). Early outcomes included death and perioperative complications. Late outcomes were survival, probability of aortic insufficiency, and reintervention up to 20 years of follow-up. Median follow-up was 17.8 years (interquartile range, 12.0-20.6 years) for the entire matched cohort.ResultsBaseline variables were similar between reimplantation and remodeling patients after matching: age (39 ± 12 vs 40 ± 13 years, P = .75) and male sex (28 [64%] vs 15 [63%], P = 1.0). Similar 20-year survival was observed after reimplantation compared with remodeling (82% vs 72%, P = .20), whereas the probability of developing greater than mild aortic insufficiency at 20 years was increased after remodeling (5.8% vs 13%, P = .013). More patients underwent reoperation on the aortic valve after a remodeling procedure than after reimplantation of the aortic valve (18% vs 0%, P = .018).ConclusionsVSRR provides excellent long-term survival and freedom from valve-related complications outcomes in patients with MFS. Reimplantation of the aortic valve was associated with a lower risk of aortic valve reoperation and aortic insufficiency than the remodeling procedure after 2 decades of follow-up.
