RESUMO
OBJECTIVE: Since its inception in the early 2000s, hybrid arch repair (HAR) has evolved from novel approach to well-established treatment modality for aortic arch pathology in appropriately selected patients. Despite this nearly 20-year history of use, long-term results of HAR remain to be determined. As such, objectives of this study are to detail the long-term outcomes for HAR within an expanded classification scheme. METHODS: From August 2005 to August 2022, 163 consecutive patients underwent HAR at a single referral institution. Operative approach was selected according to an institutional algorithm and included zone 0/1 HAR in 25% (n = 40), type I HAR in 34% (n = 56), and type II/III HAR in 41% (n = 67). Specific zone 0/1 technique was zone 1 HAR in 31 (78%), zone 0 with innominate snorkel (zone 0S HAR) in 7 (18%), and zone 0 with single side-branch endograft (zone 0B HAR) in 2 (5%). The 30-day and long-term outcomes, including overall and aortic-specific survival, as well as freedom from reintervention, were assessed. RESULTS: The mean age was 63 ± 13 years and almost one-half of patients (47% [n = 77]) had prior sternotomy. Presenting pathology included degenerative aneurysm in 44% (n = 71), residual dissection after prior type A repair in 38% (n = 62), chronic type B dissection in 12% (n = 20), and other indications in 6% (n = 10). Operative outcomes included 9% mortality (n = 14) at 30 days, 5% mortality (n = 8) in hospital, 4% stroke (n = 7), 2% new dialysis (n = 3), and 2% permanent paraparesis/plegia (n = 3). The median follow-up was 44 month (interquartile range, 12-84 months). Overall survival was 59% and 47% at 5 and 10 years, respectively, whereas aorta-specific survival was 86% and 84% at the same time points. At 5 and 10 years, freedom from major reintervention was 92% and 91%, respectively. Institutional experience had a significant impact on both early and late outcomes: comparing the first (2005-2012) and second (2013-2022) halves of the series, 30-day mortality decreased from 14% to 1% (P = .01) and stroke from 6% to 3% (P = .62). Improved operative outcomes were accompanied by improved late survival, with 78% of patients in the later era vs 45% in the earlier era surviving to 5 years. CONCLUSIONS: HAR is associated with excellent operative outcomes, as well as sustained protection from adverse aortic events as evidenced by high long-term aorta-specific survival and freedom from reintervention. However, surgeon and institutional experience appear to play a major role in achieving these superior outcomes, with a five-fold decrease in operative mortality and a two-fold decrease in stroke rate in the latter half of the series. These long-term results expand on prior midterm data and continue to support use of HAR for properly selected patients with arch disease.

BACKGROUND: Minimally invasive distal pancreatectomy (MIDP) has established advantages over the open approach. The costs associated with robotic DP (RDP) versus laparoscopic DP (LDP) make the robotic approach controversial. We sought to compare outcomes and cost of LDP and RDP using propensity matching analysis at our institution. METHODS: Patients undergoing LDP or RDP between 2000 and 2021 were retrospectively identified. Patients were optimally matched using age, gender, American Society of Anesthesiologists status, body mass index, and tumor size. Between-group differences were analyzed using the Wilcoxon signed-rank test for continuous data, and the McNemar's test for categorical data. Outcomes included operative duration, conversion to open surgery, postoperative length of stay, pancreatic fistula rate, pseudocyst requiring intervention, and costs. RESULTS: 298 patients underwent MIDP, 180 (60%) were laparoscopic and 118 (40%) were robotic. All RDPs were matched 1:1 to a laparoscopic case with absolute standardized mean differences for all matching covariates below 0.10, except for tumor type (0.16). RDP had longer operative times (268 vs 178 min, p < 0.01), shorter length of stay (2 vs 4 days, p < 0.01), fewer biochemical pancreatic leaks (11.9% vs 34.7%, p < 0.01), and fewer interventional radiological drainage (0% vs 5.9%, p = 0.01). The number of pancreatic fistulas (11.9% vs 5.1%, p = 0.12), collections requiring antibiotics or intervention (11.9% vs 5.1%, p = 0.12), and conversion rates (3.4% vs 5.1%, p = 0.72) were comparable between the two groups. The total direct index admission costs for RDP were 1.01 times higher than for LDP for FY16-19 (p = 0.372), and 1.33 times higher for FY20-22 (p = 0.031). CONCLUSIONS: Although RDP required longer operative times than LDP, postoperative stays were shorter. The procedure cost of RDP was modestly more expensive than LDP, though this was partially offset by reduced hospital stay and reintervention rate.

OBJECTIVE: To determine the threshold annualized esophagectomy volume that is associated with improved survival, oncologic resection, and postoperative outcomes. BACKGROUND: Esophagectomy at high-volume centers is associated with improved outcomes; however, the definition of high-volume remains debated. METHODS: The 2004 to 2016 National Cancer Database was queried for patients with clinical stage I to III esophageal cancer undergoing esophagectomy. Center esophagectomy volume was modeled as a continuous variable using restricted cubic splines. Maximally selected ranks were used to identify an inflection point of center volume and survival. Survival was compared using multivariable Cox proportional hazards methods. Multivariable logistic regression was used to examine secondary outcomes. RESULTS: Overall, 13,493 patients met study criteria. Median center esophagectomy volume was 8.2 (interquartile range: 3.2-17.2) cases per year. On restricted cubic splines, inflection points were identified at 9 and 30 cases per year. A multivariable Cox model was constructed modeling annualized center surgical volume as a continuous variable using 3 linear splines and inflection points at 9 and 30 cases per year. On multivariable analysis, increasing center volume up to 9 cases per year was associated with a substantial survival benefit (hazard ratio: 0.97, 95% confidence interval, 0.95-0.98, P ≤0.001). On multivariable logistic regression, factors associated with undergoing surgery at a high-volume center (>9 cases per year) included private insurance, care at an academic center, completion of high school education, and greater travel distance. CONCLUSIONS: This National Cancer Database study utilizing multivariable analysis and restricted cubic splines suggests the threshold definition of a high-volume esophagectomy center as one that performs at least 10 operations a year.

INTRODUCTION: A well-known complication of veno-arterial extracorporeal membrane oxygenation (VA ECMO) is differential hypoxia, in which poorly-oxygenated blood ejected from the left ventricle mixes with and displaces well-oxygenated blood from the circuit, thereby causing cerebral hypoxia and ischemia. We sought to characterize the impact of patient size and anatomy on cerebral perfusion under a range of different VA ECMO flow conditions. METHODS: We use one-dimensional (1D) flow simulations to investigate mixing zone location and cerebral perfusion across 10 different levels of VA ECMO support in eight semi-idealized patient geometries, for a total of 80 scenarios. Measured outcomes included mixing zone location and cerebral blood flow (CBF). RESULTS: Depending on patient anatomy, we found that a VA ECMO support ranging between 67-97% of a patient's ideal cardiac output was needed to perfuse the brain. In some cases, VA ECMO flows exceeding 90% of the patient's ideal cardiac output are needed for adequate cerebral perfusion. CONCLUSIONS: Individual patient anatomy markedly affects mixing zone location and cerebral perfusion in VA ECMO. Future fluid simulations of VA ECMO physiology should incorporate varied patient sizes and geometries in order to best provide insights toward reducing neurologic injury and improved outcomes in this patient population.
RESUMO
BACKGROUND: Heart donation after donor brain death from cardiac arrest despite successful resuscitation may be associated with worse recipient outcomes due to potential graft ischemia or underlying rhythmic/structural defects. However, selected grafts from such donors often have normal cardiac function and anatomy. We investigated whether a cardiovascular mechanism of donor brain death (CV-DBD) was associated with worse recipient outcomes. METHODS: We queried the United Network for Organ Sharing (UNOS) database for first-time, single-organ, adult (age 18+) heart transplant recipients and their associated donors between January 2005 and March 2021. Recipients were stratified by donor status (CV-DBD vs. non-CV-DBD). We performed multivariable Cox proportional hazards modeling to ascertain whether receiving a CV-DBD graft was independently associated with mortality. RESULTS: Of 35,833 included recipients, 2,702 (7.5%) received CV-DBD grafts. The associated donors were significantly more likely to be female, older, and have a history of diabetes, hypertension, and substance use (all p < .001). On unadjusted Kaplan-Meier analysis, CV-DBD recipients had a significantly reduced median survival than non-CV-DBD recipients (12.0 vs. 13.1 years, log-rank p = .04). However, after adjusting for donor/recipient age, recipient comorbidities, annualized center volume, and transplantation era, CV-DBD organ status was not associated with recipient mortality (hazard ratio: 1.05, 95% confidence interval: 0.96-1.13, p = .28). CONCLUSION: In this analysis of over 35,000 heart transplants, CV-DBD status was not associated with adjusted recipient survival. Donor brain death due to cardiac arrest should not be an absolute contraindication to heart donation, although graft function should be carefully assessed before transplantation.

BACKGROUND: Severe necrotizing pancreatitis may result in midbody necrosis and ductal disruption leaving an isolated pancreatic tail. The purpose of this study was to characterize outcomes among patients with an isolated tail remnant who underwent transgastric drainage or necrosectomy (endoscopic or surgical) and determine the need for subsequent operative management. MATERIALS AND METHODS: Patients with necrotizing pancreatitis and retrogastric walled-off collections treated by surgical transgastric necrosectomy or endoscopic cystgastrostomy ± necrosectomy between 2009 and 2017 were identified by a retrospective chart review. All available preprocedure and postprocedure imaging was reviewed for evidence of isolated distal pancreatic tail remnants. RESULTS: Seventy-four patients were included (40 surgical and 34 endoscopic). All the patients in the surgical group underwent laparoscopic transgastric necrosectomy; the endoscopic group consisted of 26 patients for pseudocyst drainage and eight patients for necrosectomy. A disconnected pancreatic tail was identified in 22 (29%) patients (13 laparoscopic and nine endoscopic). After the creation of the "cystgastrostomy," there were no external fistulas despite the viable tail. Of the 22 patients, four patients developed symptoms at a median of 23 months (two, recurrent episodic pancreatitis; two, intractable pain). Two patients (both initially in endoscopic group) ultimately required distal pancreatectomy and splenectomy at 24 and 6 months after index procedure. CONCLUSIONS: Patients with a walled-off retrogastric collection and an isolated viable tail are effectively managed by a transgastric approach. Despite this seemingly "unstable anatomy," the creation of an internal fistula via surgical or endoscopic "cystgastrostomy" avoids external fistulas/drains and the short-term necessity of surgical distal pancreatectomy. A very small subset requires intervention for late symptoms.

This review will discuss the medical management of pulmonary hypertension in patients with left ventricular assist devices. Although much has been written on the management of primary pulmonary hypertension, also called pulmonary arterial hypertension, this review will instead focus on the treatment of pulmonary hypertension secondary to left heart disease. The relevant pharmacotherapy can be divided into medications for treating heart failure, such as diuretics and ß-blockers, and medications for treating pulmonary hypertension. We also discuss important preoperative considerations in patients with pulmonary hypertension; the relationships between left ventricular assist devices, pulmonary hemodynamics, and right heart failure; as well as optimal perioperative and long-term postoperative medical management of pulmonary hypertension.

PURPOSR: This study created 3D CFD models of the Norwood procedure for hypoplastic left heart syndrome (HLHS) using standard angiography and echocardiogram data to investigate the impact of shunt characteristics on pulmonary artery (PA) hemodynamics. Leveraging routine clinical data offers advantages such as availability and cost-effectiveness without subjecting patients to additional invasive procedures. METHODS: Patient-specific geometries of the intrathoracic arteries of two Norwood patients were generated from biplane cineangiograms. "Virtual surgery" was then performed to simulate the hemodynamics of alternative PA shunt configurations, including shunt type (modified Blalock-Thomas-Taussig shunt (mBTTS) vs. right ventricle-to-pulmonary artery shunt (RVPAS)), shunt diameter, and pulmonary artery anastomosis angle. Left-right pulmonary flow differential, Qp/Qs, time-averaged wall shear stress (TAWSS), and oscillatory shear index (OSI) were evaluated. RESULTS: There was strong agreement between clinically measured data and CFD model output throughout the patient-specific models. Geometries with a RVPAS tended toward more balanced left-right pulmonary flow, lower Qp/Qs, and greater TAWSS and OSI than models with a mBTTS. For both shunt types, larger shunts resulted in a higher Qp/Qs and higher TAWSS, with minimal effect on OSI. Low TAWSS areas correlated with regions of low flow and changing the PA-shunt anastomosis angle to face toward low TAWSS regions increased TAWSS. CONCLUSION: Excellent correlation between clinically measured and CFD model data shows that 3D CFD models of HLHS Norwood can be developed using standard angiography and echocardiographic data. The CFD analysis also revealed consistent changes in PA TAWSS, flow differential, and OSI as a function of shunt characteristics.

BACKGROUND: Management of clinical stage II or III esophageal cancer requires multidisciplinary care. Multi-institutional care has been associated with worse survival in other malignant diseases. This study aimed to determine the impact of multi-institutional care on survival in patients with stage II or III esophageal cancer. METHODS: The 2004 to 2016 National Cancer Database was queried for patients with clinical stage II or III esophageal cancer who received neoadjuvant chemotherapy with or without radiation therapy followed by surgical resection. Patients were stratified into 2 groups: multi-institutional or single-institution care. Survival between groups was compared using Kaplan-Meier and multivariable Cox proportional hazards methods. Multivariable logistic regression was performed to identify factors associated with multi-institutional care. RESULTS: Overall, 11 399 patients met study criteria: 6569 (57.6%) received multi-institutional care and 4,830 (42.4%) received care at a single institution. In a multivariable analysis, factors associated with multi-institutional care were later year of diagnosis, greater distance from treating facility, residence in an urban or rural setting (vs metro), and residence in states without Medicaid expansion. Care at a single institution was associated with Black race, lack of insurance, and treatment at higher-volume or academic centers. Despite these differences, patients who received multi-institutional care had survival comparable to that in patients who received care at a single institution (HR, 0.97; 95% CI, 0.92-1.03; P = .30). CONCLUSIONS: In this National Cancer Database analysis, multi-institutional care was not associated with inferior overall survival. As complex cancer care becomes more regionalized, patients may consider receiving part of their cancer care closer to home, whereas traveling to surgical centers of excellence should be encouraged.

OBJECTIVES: The Hemispherical Aortic Annuloplasty Reconstructive Technology (HAART) ring is a rigid, internal and geometric device. The objective of this article is to assess the mid-term outcomes of aortic valve repair (AVr) using this prosthesis. METHODS: A prospectively maintained database was used to obtain outcomes for adult patients undergoing AVr using the HAART ring between September 2017 and June 2023. All aortic patients at our institution undergo life-long surveillance with regular assessment and valve imaging. RESULTS: Seventy-one patients underwent AVr using the HAART device: 53 had a trileaflet valve and 18 a bicuspid valve. The median age was 54 years, and most were male (79%). Many required concomitant intervention: 46% had a root procedure and 77% an arch repair. There were no in-hospital deaths, and the median postoperative stay was 5 days. At a mean follow-up of 3.9 (±1.1) years, freedom from reoperation was 94%. Late imaging demonstrated: zero trace (25%), 1+ (54%), 2+ (15%) and 4+ (6%) aortic insufficiency (AI). Eleven patients have ≥moderate AI under surveillance, all of whom have a trileaflet valve (21% of trileaflet patients). Four patients required reoperation: 3 for ring dehiscence and 1 for endocarditis. CONCLUSIONS: Although early results using the HAART device are encouraging, mid-term results raise concern as 21% of trileaflet patients developed recurrent ≥moderate AI by 4 years post-repair. We experienced 3 incidences of ring dehiscence requiring reoperation. Based on this, we recommend caution using the sub-annular approach for stabilization in patients with trileaflet aortic valves. Long-term results are needed to assess outcomes against established techniques.

BACKGROUND: Spleen-preservation during minimally invasive distal pancreatectomy (MIDP) can be technically challenging and remains controversial. Our primary aim was to compare MIDP and splenectomy with spleen-preserving MIDP. Secondarily, we compared two spleen-preserving techniques. METHODS: Adults undergoing MIDP (2007-2021) were retrospectively included in this single-center study. Intraoperative and postoperative outcomes between spleen-preservation and splenectomy and between the two spleen-preserving techniques were compared using the Mann-Whitney U test for continuous data, and Fisher's exact test for categorical data. RESULTS: Of the 293 patients who underwent MIDP, preservation of the spleen was intended in 208 (71%) patients. Spleen-preservation was achieved in 174 patients (84%) via the Warshaw technique (130; 75%) or vessel-preservation (44; 25%). The spleen-preserving group had shorter length of stay (3 vs 4 days, p < 0.01), fewer conversions to open (1 vs 12, p < 0.01) and less blood loss (p < 0.01) compared to the splenectomy group. Operative (OR) times were comparable (229 vs 214 min, p = 0.67). Except for the operative time, which was longer for the Warshaw technique (245 vs 183 min, p = 0.01), no other differences between the two spleen-preserving techniques were found. At a median follow-up of 43 (IQR 18-79) months after spleen-preservation, only 2 (1.1%) patients had required splenectomy (1 partial splenectomy for infarct/abscess after Warshaw, 1 for variceal bleeding after vessel-preserving). CONCLUSIONS: Spleen-preservation is not associated with increased risk of blood loss, longer hospital stay, conversion, nor lengthy OR times. Late splenectomy is very rarely required. Given the immune consequences of splenectomy, spleen-preservation should be strongly considered in MIDP.

Spontaneous coronary artery dissection (SCAD) is a rare but important nonatherosclerotic cause of acute coronary syndrome. Indications for revascularization and long-term outcomes of SCAD remain areas of active investigation. We report our experience with initial management strategy and long-term outcomes in SCAD. We reviewed all patients treated at our institution from 1996-2021 with a SCAD diagnosis. Demographics, comorbidities, clinical presentations, angiography findings, and management strategies were obtained by chart review. The primary outcome was a composite of cardiac death, recurrent/progressive SCAD, subsequent diagnosis of congestive heart failure, or subsequent/repeat revascularization after the initial management. Unadjusted Kaplan-Meier survival analysis was performed. Of 186 patients with a SCAD diagnosis treated at our institution, 149 (80%) were female. Medical management was the initial treatment in 134 (72.0%) patients, percutaneous coronary intervention (PCI) in 43 (23.1%), and coronary artery bypass grafting in 9 (4.8%). Surgery/PCI intervention was associated with younger age (38.8 vs 47.7â¯years, Pâ¯=â¯0.01), ST elevation myocardial infarction on presentation (67.0% vs 34.0%, Pâ¯<â¯0.001), lower ejection fraction (45.0% vs 55.0%, Pâ¯=â¯0.002), and left anterior descending coronary artery dissection (75.0% vs 51.0%, Pâ¯=â¯0.006). Ten-year freedom from our composite outcome was similar between revascularized patients and those managed with medical therapy (Pâ¯=â¯0.36). Median follow-up time was 4.5â¯years. SCAD in the setting of ST elevation myocardial infarction, left anterior descending coronary artery involvement, or decreased cardiac function suggests greater ischemic insult and was associated with initial percutaneous or surgical revascularization. Despite worse disease on initial presentation, long-term outcomes of patients undergoing revascularization are similar to medically managed patients with SCAD.
RESUMO
This review discusses the management of acute Type A aortic dissection (ATAAD) complicated by cerebral malperfusion (CMP). While prompt surgical repair is the accepted standard of care for ATAAD, there remains uncertainty and debate about the optimal management of the subgroup of ATAAD patients with CMP. Examined topics include overall survival and neurologic outcomes after surgical repair of ATAAD with CMP, how the severity of presenting neurologic deficits impacts the decision and timing of operation, predictors of postoperative neurologic recovery, and a suggested management algorithm for ATAAD with CMP based upon the best available clinical evidence.

Approximately 25% of patients require reoperation within 15 yrs of a Ross procedure. Increasing experience with valve-sparing root replacement (VSRR) has led some surgeons to spare the autograft valve. Here, we demonstrate that all valves can be surgically repaired or replaced safely during autograft VSRR. As more patients are considered for this operation, coexistent mitral, tricuspid, and pulmonic valve dysfunction should not preclude salvage of the autograft valve, nor should autograft leaflet prolapse.
