We investigated if the occurrence of preoperative right ventricular dysfunction is capable of influencing heart transplant results in terms of in-hospital mortality, incidence of primary graft dysfunction, and follow-up mortality.We retrospectively analyzed 517 patients who underwent heart transplant between January 2000 and December 2020. We defined right ventricular dysfunction (RVD), as central venous pressure (CVP)15 mm Hg and CVP/pulmonary capillary wedge pressure ratio0.63. We identified 2 subgroups in our population: 33 patients with preoperative RVD and 484 patients without RVD.In-hospital mortality was 7.9%. Severe early graft failure occurred in 6.6% of patients, with 26 patients (5.1%) needing intra-aortic balloon pump and 17 patients (3.3%) needing extracorporeal membrane oxygenation support. Clinical variables that significantly influenced in-hospital mortality were age, peripheral artery disease, and bilirubin1.5 mg/dL, while hemodynamic variables influencing in-hospital mortality were CVP (odds ratio [OR], 1.09 [confidence interval {CI}, 1.03-1.15], P = .004], pulmonary artery systolic pressure (OR, 1.02 [CI, 1.00-1.04], P = .05), CVP/pulmonary capillary wedge pressure ratio (OR, 2.78 [CI, 1.14-6.80], P = .025), pulmonary vascular resistance (OR, 1.15 [CI, 1.01-1.32], P = .042), transpulmonary gradient (TPG) (OR, 1.11 [CI, 1.03-1.18], P = .003) , diastolic transpulmonary gradient (OR, 1.10 [CI, 1.02-1.20], P = .015], together with right ventricular dysfunction (OR, 3.56 [CI, 1.44-8.80], P = .011). On the other hand, clinical variables influencing the incidence of early graft failure were body mass index (calculated as weight in kilograms divided by height in meters squared)30, peripheral artery disease, bilirubin1.5 mg/dL, Model for End-Stage Liver Disease score excluding international normalized ratio before transplant, and preoperative extracorporeal membrane oxygenation support, while hemodynamic variables were pulmonary arterial systolic pressure (OR, 1.03 [CI, 1.00-1.05], P = .016), TPG (OR, 1.08 [1.01-1.17], P = .03), and right ventricular dysfunction (OR, 3.00 [CI, 1.07-8.40] P = .046). On the multivariable analysis, RVD and TPG were independent predictors of in-hospital mortality, while only TPG was a predictor of early graft failure. Follow-up mortality was 38.7% and was influenced by recipient age, recipient body mass index, and preoperative diabetes. Moreover, 1-, 5-, and 10-year survival of patients with preoperative RVD was significantly worse than patients without RVD (log-rank = 0.001).In our population, RVD influenced both in-hospital and long-term results after heart transplant. For these reasons, it appears crucially important to optimize preoperative right ventricular function to improve these patients' outcomes.

Postinfarction ventricular septal rupture (VSR) represents a well-known mechanical complication of myocardial infarction, determining cardiogenic shock with high mortality rates. Surgical correction requires significant expertise to avoid cardiac rupture, uncontrollable bleeding, residual shunts, heart failure, and death. In the last year, we observed a substantial increase of VSR at our hospital, related to the delayed presentation of people with acute chest pain to the emergency departments during the coronavirus disease 2019 pandemic. We discuss our innovative triple-layer patch technique in a recent consecutive series of 8 patients. This technique proved effective in all patients, with no residual shunt or cardiac rupture.

OBJECTIVES The frozen elephant trunk technique is an increasingly common treatment for extensive disease of the thoracic aorta. The objective of the study was to evaluate the outcomes of frozen elephant trunk specifically in chronic (residual) aortic dissections, focusing on downstream aortic remodelling. METHODS Between 2013 and 2019, a total of 28 patients were treated using the Vascutek Thoraflex hybrid graft at our institution for chronic dissections/post-dissection aneurysms. Immediate and follow-up outcomes were studied, as well as the changes in total aortic diameter, true lumen and false lumen diameter and the status of the false lumen at 3 different levels of the thoraco-abdominal aorta. RESULTS No in-hospital or 30-day mortality was observed, temporary paraparesis rate was 7% and disabling stroke incidence was 14.3%. Freedom from all-cause mortality at 2 years was 91.6 ± 5.7%, while freedom from reintervention on the downstream aorta at 2 years was 59.1 ± 10.8%. Positive aortic remodelling was achieved in 50.0%, with an enlargement in the true lumen and a reduction of the false lumen not only at the level of the proximal descending aorta with 73.1% of complete thrombosis but also at the level of the distal descending thoracic aorta, with 41.7% of complete thrombosis. CONCLUSIONS The frozen elephant trunk is a good solution in chronic (residual) downstream aortic dissections inducing positive aortic remodelling and preventing from II stage operations or allowing an endovascular approach.

Peripheral extracorporeal membrane oxygenation (ECMO) setting remains a valid option to treat cardiogenic shock (CS). We investigated a percutaneous approach to unload the left ventricle (LV) while on veno-arterial (v-a) peripheral ECMO support. Between 2017 and 2018, eight patients (three females, mean age: 49.6 years old, and five males, mean age: 58 years old, respectively) suffered refractory CS due to acute myocardial infarction (n = 4), acute myocarditis (n = 2), acute decompensation on chronic heart failure (n = 1), and primary graft failure after heart transplantation (Htx) (n = 1), respectively. After a multidisciplinary CS team discussion, it was decided to proceed with peripheral v-a ECMO placement and percutaneous LV venting via right internal jugular vein access to drain the pulmonary artery (PA), in the hybrid operating room. In a single postcardiotomy case, the PA trunk was vented centrally. Mean ECMO support time was 8.5 days. Seven (87.5%) patients were successfully weaned from ECMO and one (12.5%) successfully bridged to Htx. All patients were successfully discharged after treatment except for a single case who died due to sepsis. In case of not recommended usage of LV apical venting, the adoption of v-a peripheral ECMO support associated with percutaneous PA drainage enables the rapid onset of extracorporeal life support with an effective biventricular unloading.

OBJECTIVES A heart transplant (Htx) remains the gold standard treatment for patients with advanced heart failure. Considering the limited availability of organs, donor risk scores might improve organ selection and allocation. The objective of the study was to compare United Network for Organ Sharing, RADIAL and Eurotransplant scoring models in calculating post-Htx outcomes in an Italian Htx population. METHODS Between January 2000 and December 2017, a total of 461 adult patients underwent Htxs. United Network for Organ Sharing, RADIAL and Eurotransplant scores were calculated. Clinical features and donor risk scores were tested to identify preoperative, intraoperative and postoperative risk variables and eventually validate the scores on our population. RESULTS Early graft failure was detected in 16.1% (74/461). Post-Htx extracorporeal life support was used in 11.1% (51/461). Of the donor-related factors, the use of noradrenaline (P = 0.015) negatively influenced early outcomes, whereas an ischaemic time >240 min (P = 0.037) influenced early graft failure occurrence. The Eurotransplant donor score did not impact outcomes; the RADIAL score significantly influenced both early and late mortality; and the United Network for Organ Sharing score influenced only late mortality. On the multivariable analysis, after adjustment of scores per cohort, noradrenaline infusion was the main independent predictor of in-hospital mortality for the donors, whereas age of the recipient [odds ratio (OR) 1.003, 1.003–1.081; P = 0.032] and use of preoperative extracorporeal membrane oxygenation (OR 3.320, 1.124–9.805; P = 0.030) were the main independent predictors for the recipients. CONCLUSIONS None of the validated donor scoring systems fully behave as reliable predictors of transplant outcomes. According to our ‘local only’ graft selection, specific donor and recipient risk variables should be monitored in order to predict early and late outcomes satisfactorily.

Mechanical circulatory supports with left ventricular assist devices (LVAD) are nowadays an established treatment in end-stage heart failure for those patients who are waiting for an organ donation or are unsuitable for transplantation. The duration of LVAD support is variable, depending on the device, the intention to treat and the issues occurring during treatment, which can change the purpose treatment or accelerate the transplantation. Moreover, length of reported supports in the literature is heterogenous. In here, we present the clinical and surgical case of the longest LVAD support reported in the literature, as a bridge to transplantation, with axial pump Jarvik 2000 (Jarvik Heart, Inc, New York, NY).

Background: The occurrence of early graft failure (EGF) after heart transplantation (Htx) often requires a mechanical circulatory support (MCS) therapy. The aims of our study were to identify risk factors of mechanically supported severe EGF and evaluate their impact on both early and late outcomes. Methods: Between January 2000 and December 2019, 499 consecutive adult patients underwent Htx at our institution. Severe EGF was defined as the need for extracorporeal life support (ECLS) within 24 hours after surgery. All available recipient and donor variables were retrospectively analyzed. Results: Overall, EGF occurred in 58 (11.6%) patients. Post-Htx peripheral or central ECLS was necessary in 32 (6.4%) cases. Independent predictors of severe EGF were, in the recipient group, preoperative transpulmonary gradient (TPG) >12 mm Hg (odds ratio [OR] 4.1, P =. 013), preoperative inotropic score >10 (OR 7.3, P =. 0001), and pre-Htx ECLS support (OR 5.2, P =. 015), while in the donors, a Eurotransplant donor score ≥17 (OR 8.5, P =. 005). The absence of EGF was related with a better survival at 1 year and 5 years (94% and 85%, respectively) compared with EGF requiring ECLS population (36% and 28% at 1 year and 5 years, respectively; P

Purpose Chronic thromboembolic pulmonary hypertension (CTEPH) is the only type of pulmonary hypertension (PH) with a surgical resolution which is the Pulmonary Thrombo-Endarterectomy (PTE) operation. Fibrotic thrombus extraction allows pulmonary vascular resistances (PVR) reduction until normalisation in most of cases. However, this sentence might be controversial since results are conditioned by the center experience on patients's selection, operation's timing, skills and management of such complex pathology. Seventeen years performing PTE and our multidisciplinary approach allowed us to obtain very good results. In here we report our data progress and results of PTE for CTEPH. Methods A total of 177 patients underwent PTE from 2003 until 2020. From 2003 to 2012 (Group 1) 96 patients were operated avoiding Deep Hypothermic Circulatory Arrest (DHCA) being applied only when blood bronchial flow ruled out a complete endarterectomy. Group 2, included 81 patients operated rom 2012 until the present, when DHCA was routinely adopted. Furthermore, the event of the Balloon Pulmonary Angioplasty (BPA) in 2015, conceded us a therapeutic alternative in high risk or unsuitable PTE patients. The impact of these and other variables in patients population profile and results of both groups have been retrospectively compare and analysed. Results Most relevant preoperative differences were related to worst clinical status and associated pathologies in Group 1 and wider use of specific pulmonary vasodilator in Group 2. Cross clamp time as well as time of cardiopulmonary bypass were significantly shorter in Group 2 in spite of a mean DHCA time of 33 minutes. In-hospital mortality and need of postoperative ECMO was respectively 15.6% vs 3.7% and 15.6% vs 8.6% in group 1 and 2 (p 0.001). Pulmonary hemodynamic as well as long term outcome equally and significantly improved in both groups. Conclusion Our reported results demonstrate that, DHCA is the best approach to perform PTE for CTEPH. Certainly experience, protocols and a multidisciplinary approach contribute to obtain the best hemodynamics, surgical and clinical outcomes.

Purpose To investigate the predictive value of Acute Physiology, Age and Chronic Health Evaluation (APACHE) II, Simplified Acute Physiology (SAPS) II and Sequential Organ Failure Assessment (SOFA) scores for patient selection and timing to Extracorporeal Life Support (ECLS) as treatment of refractory cardiogenic shock. Methods Retrospective analysis of a prospectively-maintained operative dataset. Results Our study population included 185 patients receiving ECLS at our department between 2006 and 2018. Patient median age was 50.6 years; 62% were male. The most frequent reason for ECLS need, in our subset of patients, was post-cardiotomy syndrome (52.4%) followed by acute decompensation of chronic heart failure (17.5%), isolated right ventricular dysfunction (16.2%), acute myocardial infarction (10.2%) and myocarditis (3.7%). Median duration of ECLS was 8.9 days. Forty-one patients (22.2%) received heart transplantation. In-hospital mortality was 34.6% on ECLS running and 25.9% after ECLS removal. Multivariate regression analysis showed patient age, ECLS duration and bridge to transplantation (BTT) category as indipendent predictors of death (p Conclusion This study confirms the poor prognosis of critically ill patients receiving ECLS support. The APACHE II and SOFA scores, mainly, proved to be a reproducible evaluation tool with high prognostic abilities. In our population, age >65 years, ECLS duration >10 days and BTT ECLS intention appear to impact negatively.

Purpose Heart transplantation (Htx) remains the gold standard as treatment of patients with advanced heart failure. Donor and recipient characteristics have changed dramatically in recent years, leading to more complex decision-making regarding organ acceptance and postoperative management. Primary aim of the study was to identify donor risk factors variables impacting on in-hospital mortality, early graft failure and follow-up mortality; secondary objective was to validate the available international donor risk scores. Methods Between January 2000 and December 2017, 461 adult patients underwent Htx. UNOS, RADIAL and Eurotransplant scores have been calculated. Clinical features and donor risk scores have been tested in order to identify pre-, intra- and post-operative risk variables and eventually validate the scores on our population. Results Post-Htx extracorporeal life support (ECLS) was used in 11.1% (51/461). Of the donor related factors, peak of troponine (p 240 minutes (p=0.037) influenced EGF occurrence. The Eurotransplant donor score didn't impact on outcomes, the RADIAL significantly influenced both on early (p=0.02) and late mortality (p=0.004) while the UNOS on late mortality only (p=0.03). On the multivariate model, after adjustment per cohort of scores, noradrenaline infusion resulted to be an independent predictor of in-hospital mortality in the Eurotransplant score >17 population, recipient pre-Htx ECLS and BMI >30 were independent predictors of EGF in the UNOS score >6 population, and recipient age >60 was predictor of late mortality in the RADIAL score >5 (figure 1). Conclusion Actual heart donor scoring systems do not fully behave as reliable predictors of transplant outcomes. Therefore, every transplant institution should consider developing a local donor scoring systemto provide their own standard graft selection thus preserving the outcomes.

Objectives: The aim of this study was to identify the risk factors associated with early mortality after postcardiotomy venoarterial extracorporeal membrane oxygenation. Methods: This is an analysis of the postcardiotomy extracorporeal membrane oxygenation registry, a retrospective multicenter cohort study including 781 patients aged more than 18 years who required venoarterial extracorporeal membrane oxygenation for cardiopulmonary failure after cardiac surgery from 2010 to 2018 at 19 cardiac surgery centers. Results: After a mean venoarterial extracorporeal membrane oxygenation therapy of 6.9 ± 6.2 days, hospital and 1–year mortality were 64.4% and 67.2%, respectively. Hospital mortality after venoarterial extracorporeal membrane oxygenation therapy for more than 7 days was 60.5% (P = 0.105). Centers that had treated more than 50 patients with postcardiotomy venoarterial extracorporeal membrane oxygenation had a significantly lower hospital mortality than lower–volume centers (60.7% vs 70.7%, adjusted odds ratio, 0.58; 95% confidence interval, 0.41–0.82). The postcardiotomy extracorporeal membrane oxygenation score was derived by assigning a weighted integer to each independent pre–venoarterial extracorporeal membrane oxygenation predictors of hospital mortality as follows: female gender (1 point), advanced age (60–69 years, 2 points; ≥70 years, 4 points), prior cardiac surgery (1 point), arterial lactate 6.0 mmol/L or greater before venoarterial extracorporeal membrane oxygenation (2 points), aortic arch surgery (4 points), and preoperative stroke/unconsciousness (5 points). The hospital mortality rates according to the postcardiotomy extracorporeal membrane oxygenation score was 0 point, 45.6%; 1 point, 40.5%; 2 points, 51.1%; 3 points, 57.8%; 4 points, 70.7%; 5 points, 68.3%; 6 points, 77.5%; and 7 points or more, 89.7% (P < 0.0001). Conclusions: Age, female gender, prior cardiac surgery, preoperative acute neurologic events, aortic arch surgery, and increased arterial lactate were associated with increased risk of early mortality after postcardiotomy venoarterial extracorporeal membrane oxygenation. Center experience with postcardiotomy venoarterial extracorporeal membrane oxygenation may contribute to improved results.

Background We hypothesized that cannulation strategy in venoarterial extracorporeal membrane oxygenation (VA-ECMO) could play a crucial role in the perioperative survival of patients affected by postcardiotomy shock. Methods Between January 2010 and March 2018, 781 adult patients receiving VA-ECMO for postcardiotomy shock at 19 cardiac surgical centers were retrieved from the Postcardiotomy Veno-arterial Extracorporeal Membrane Oxygenation study registry. A parallel systematic review and meta-analysis (PubMed/MEDLINE, Embase, and Cochrane Library) through December 2018 was also accomplished. Results Central and peripheral VA-ECMO cannulation were performed in 245 (31.4%) and 536 (68.6%) patients, respectively. Main indications for the institution VA-ECMO were failure to wean from cardiopulmonary bypass (38%) and heart failure following cardiopulmonary bypass weaning (48%). The doubly robust analysis after inverse probability treatment weighting by propensity score demonstrated that central VA-ECMO was associated with greater hospital mortality (odds ratio 1.54; 95% confidence interval, 1.09-2.18), reoperation for bleeding/tamponade (odds ratio, 1.96; 95% confidence interval, 1.37-2.81), and transfusion of more than 9 RBC units (odds ratio, 2.42; 95% confidence interval, 1.59-3.67). The systematic review provided a total of 2491 individuals with postcardiotomy shock treated with VA-ECMO. Pooled prevalence of in-hospital/30-day mortality in overall patient population was 66.6% (95% confidence interval, 64.7-68.4%), and pooled unadjusted risk ratio analysis confirmed that patients undergoing peripheral VA-ECMO had a lower in-hospital/30-day mortality than patients undergoing central cannulation (risk ratio, 0.92; 95% confidence interval, 0.87-0.98). Adjustments for important confounders did not alter our results. Conclusions In patients with postcardiotomy shock treated with VA-ECMO, central cannulation was associated with greater in-hospital mortality than peripheral cannulation.

Intramural hematoma (IMH) is a well-recognized type of acute aortic syndrome with a significant rate of progression in more than 60% of cases (1,2). According to the most recent European guidelines, the treatment of a type A IMH follows the same recommendations as for type A aortic dissection (1,3). Therefore, in case of aortic arch involvement, a more radical treatment such as frozen elephant trunk (FET) should be considered. The rationale to use this kind of approach is to prepare for a second stage endovascular procedure, especially in case of distal downstream thoracoabdominal aorta involvement and in young patients. In this video, we illustrate the treatment of a type A IMH using the Vascutek Thoraflex hybrid prosthesis.

Introduction: Preoperative liver and renal dysfunction remain surgical risk factors for both postoperative morbidity and mortality. The Model of End-Stage Liver Disease Excluding INR (international normalized ratio), or MELD-XI, score calculation may help as a predictor in patients with advanced heart failure. We analyzed the impact of progressive elevated MELD-XI values among recipients of heart transplant at our institution. Methods: The data of a total of 425 consecutive adult patients who underwent heart transplantation, between January 2000 and August 2018, have been reviewed and divided into 3 cohorts according to preoperative MELD-XI calculations (MELD-XI < 11; MELD-XI 11-18; and MELD-XI > 18). Early and late outcomes have been analyzed. Results: Patients with a MELD-XI score > 18 had a more critical clinical condition preoperatively and had a higher risk of early mortality (hazard ratio [HR] 1.45 [1.11-1.67], P < .001). They showed high risk for postoperative dialysis (HR 2.8 [1.5-5.3], P < .001), rethoracothomy for bleeding (HR 2.1 [1.2-4.1], P = .001), prolonged time of mechanical ventilation, time of intensive care unit stay (HR 2.2 [1.3-3.8], P = .005), and graft failure requiring mechanical circulatory support (HR 1.9 [1.1-3.3], P = .003). After risk adjustment per MELD-XI cohort, ischemic dilated cardiomyopathy, redo operation, and cold ischemic time > 240 minutes resulted in being the strongest predictors of early mortality (P < .001). The 5-year and 10-year survival for MELD-XI > 18 cohort was 63% and 47% vs 72% and 59% in the control group (MELD-XI < 18) (log-rank, P < .001). Conclusions: Patients with an elevated preoperative MELD-XI profile presented more comorbidities and significantly lower survival. This suggests the MELD-XI score may provide further insight into appropriate recipient and eventual donor selection. Renal insufficiency and congestive hepatopathy should be properly optimized before heart transplantation.

Left ventricular assist device graft protection and its intraoperative orientation continues to be a major concern in bridge-to-transplant strategy. Different techniques have been described, including the adoption of a standard full sternotomy approach. We describe our institutional experience of placement of the with HeartWare HVAD® implantable continuous flow pump, with outflow graft tunnelling through the transverse sinus to prepare patients in need of eventual re-sternotomy. Surgical tips are provided in the tutorial videos both for HVAD® placement, and for explantation at the time of heart transplantation.

Purpose Currently, guide for appropriate donor sizing in recipients mostly focuses on donor-recipient body weight matching. The purpose is to retrospectively determine the impact of predicted heart mass (pHM)-based size matching among recipients on heart transplantation (HT) outcomes. Methods According to our institutional registry, 512 consecutive adult patients underwent HT between January 2000 and August 2020. For each patient, pHM and donor-recipient pHM ratio have been calculated (4 patients were excluded for missing anthropometric data). Patients were partitioned into quintiles in terms of pHM ratio: Undersizing2 (n=101), Undersizing1 (n=102), Reference (n=102), Oversizing1 (n=102), Oversizing2 (n=101) with a mean pHM donor-recipient ratio of 0.81, 0.96, 1.04, 1.12, 1.28, respectively. Severe early graft failure, 30-day, 90-day and 1-year mortality were analyzed as early outcomes. Results Several characteristics were significantly different between groups. Recipients of the most oversized group were mostly male (p 0.05). Kaplan-Mayer and Cox-regression analysis after adjustment for pHM ratio subgroups did not show any difference in outcomes (p>0.05). Conclusion A wide range of pHM donor-recipient ratios seem to be safe (0.81-1.28). Providing a pHM-based oversized graft to more compromised patients may preserve good outcomes. Instead, low risk profile patients may have acceptable outcomes even in the presence of extremely undersized pHM ratio calculation. A careful allocation of organs, by considering a pHM ratio mismatch, may balance rescue preoperative clinical profiles and preserve HT outcomes.

The frozen elephant trunk might be considered one of the most appreciated innovations during the last decades to treat complex thoracic aortic lesions. Many useful tips have been progressively introduced to standardize the procedures and, nowadays, the improved post-operative outcomes contributed to spread the procedure. The following article will provide a comprehensive review analysis of the Frozen Elephant Trunk (FET) technique, throughout the current available devices, possible surgical indications and primary post-operative complications.

BACKGROUND: Surgical ventricular reshaping (SVR) is a treatment option for patients with severe ischaemic heart failure (HF). Recently, a new minimally invasive, hybrid technique named “less invasive ventricular enhancement” (LIVE), has been developed adopting the Reviven™ Myocardial Anchoring System (BioVentrix Inc., San Ramon, CA, USA). METHODS: Between January 2015 and November 2018, 7 patients (5 men and 2 women; mean age 72±8.9 years) underwent LIVE procedure at our institution. RESULTS: Procedural success was 100%. A total anchors number of 3.0±0.9 was used to reshape the left ventricle (LV). Preoperative and postoperative echocardiographic assessments showed an increase of LV ejection fraction (EF) from 22.8%±8.1% to 35%±7.2% (P=0.001) and a decrease of LV volumes in terms of LV end-systolic volume index (LVESVI), from 93.2±10.5 to 52.1±15.1 mL/m(2) (P

Background: There is uncertainty whether venoarterial extracorporeal membrane oxygenation (VA-ECMO) should be used in older patients with cardiopulmonary failure after cardiac surgery. Methods: This was a retrospective multicenter study of 781 patients who required postcardiotomy VA-ECMO for cardiopulmonary failure after adult cardiac surgery from 2010 to 2018 at 19 cardiac surgery centers. A parallel systematic review with meta-analysis of the literature was performed. Results: The hospital mortality in the overall Postcardiotomy Venoarterial Extracorporeal Membrane Oxygenation (PC-ECMO) series was 64.4%. A total of 255 patients were 70 years old or older (32.7%), and their hospital mortality was significantly higher than in younger patients (76.1% vs 58.7%; adjusted odds ratio, 2.199; 95% confidence interval [CI], 1.536 to 3.149). Arterial lactate level greater than 6 mmol/L before starting VA-ECMO was the only predictor of hospital mortality among patients 70 years old or older in univariate analysis (82.6% vs 70.4%; P = 0.029). Meta-analysis of current and previous studies showed that early mortality after postcardiotomy VA-ECMO was significantly higher in patients aged 70 years or older compared with younger patients (odds ratio, 2.09; 95% CI, 1.59 to 2.75; 5 studies including 1547 patients; I², 5.9%). The pooled early mortality rate among patients aged 70 years or older was 78.8% (95% CI, 74.1 to 83.5; 6 studies including 617 patients; I², 41.8%). Two studies reported 1-year mortality (including hospital mortality) of 79.9% and 75.6%, respectively, in patients 70 years old or older. Conclusions: Advanced age should not be considered a contraindication for postcardiotomy VA-ECMO. However, in view of the high risk of early mortality, meaningful scrutiny is needed before using VA-ECMO after cardiac surgery in older patients.

Background: Pulmonary endarterectomy (PEA) is a surgical intervention reserved for patients with chronic thromboembolic pulmonary hypertension (CTEPH). In some cases, temporary circulatory support [extracorporeal life support (ECLS)] is required after PEA. Rates of ECLS requirement varies between centers. Reasons for institution of ECLS include respiratory failure, cardiac failure (or both respiratory and cardiac failure), bleeding, and reperfusion edema. This article reviews the experience of ECLS after PEA from the current literature, as well as our own institution’s experience as a CTEPH multidisciplinary center. Methods: A literature review was conducted along with a retrospective chart review from 15 years of our PEA program. Results: The literature demonstrates many different approaches are used for mechanically supporting patients who develop complications after PEA. Variations in approach stem from differing indications such as, respiratory failure rather than hemodynamic compromise (or vice versa), time of implantation (immediately in operating room or delayed after surgery) and many other causes. In our center, 12.3% (19/154) of patients need ECLS with extracorporeal membrane oxygenator (ECMO) after PEA procedure. Implantation was mainly in the operating room before or immediately after weaning from cardiopulmonary bypass and mostly peripheral cannulation was used. ECMO lasted an average of 11±8 days. And 52.6% (10 of 19 patients) of patients were weaned from ECLS and of this, 70% (7 of 10 patients) were discharged. Conclusions: In some cases of PEA, ECLS is needed post-operatively. Expert teams should consider this possibility pre-operatively based on predisposing characteristics. The need for ECMO shouldn’t be “di per se” a contraindication to surgery but might be considered in the surgical risk estimation. The ideal setup is not fixed and depends on the center’s practices as well as indication. Even though complications do occur with ECMO, in general, results are good, being a bridge to further recovery of pulmonary hypertension (PH) or also to transplantation.

Purpose The prognostic impact of pulmonary hypertension (PH) is debated as well as the trend of pulmonary hemodynamic variables after heart transplantation (HTx). We investigated the impact of preoperative PH on postoperative survival and on the evolution of right heart hemodynamics (RHH) after HTx. Methods We reviewed the records of 431 consecutive HTx recipients, divided in a non-PH group (270 pts) and a PH group (161 pts).PH was defined as pulmonary vascular resistance ≥2.5 Wood units (WU) at right heat catheterization: mild (97 pts; PVR: 2.5-3.4WU), moderate (41 pts; PVR: 3.5-4.9WU) and severe PH (23 pts; PVR ≥5.0WU). RHH [systolic/mean/diastolic pulmonary artery-systolic-pressure (PAP), pulmonary-capillary-wedge-pressure (PCWP), transpulmonary gradient (TPG), cardiac output (CO), pulmonary vascular resistance (PVR), pulmonary-arterial-pulsatility-index (PAPi) and right-ventricle-stroke-work-index (RVSWI)] were measured before HTX and 3, 6, 12 months, 3, 5 years after HTX. Survival analysis was conducted using Kaplan-Meier curves. Results Preoperatively, patients with severe PH had significantly (P Conclusion Pre-transplant PH is an independent predictor of early mortality after HTx, not affecting long-term survival even when severe. After an early significant improvement of RHH, mean PAP, TPG and PVR increase while CO, PAPi and RVSWI decrease during follow-up. A rigorous monitoring of RHH must be scheduled during FU.

Stroke events are very common in acute type A aortic dissection. Cerebral malperfusion could manifest at presentation due to prolonged arch vessels hypoperfusion or develop after surgery for inadequate cerebral protection during arch repair. To reduce this detrimental complication there are several adjuncts that can be adopted for cerebral protection such as direct antegrade or retrograde cerebral perfusion (RCP) and use period of deep to moderate hypothermic circulatory arrest time; however, they are often insufficient as preoperative malperfusion already caused irreversible ischemic damages. The aim of the current review article is to analyze the principal series reporting on neurological injuries during type A aortic dissection to focus on the outcomes according to the type of surgical management and identify possible predictors to better manage this complication.
