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.

Aim The benefits of BioGlue as a surgical adjunct in aortic procedures have been demonstrated in several studies, but limited information is available regarding the associated histopathological findings of aortic tissue at the time of reoperation. The objective of this study was to assess, at reoperation, the histopathological characteristics of aortic tissue which has had BioGlue applied during a previous surgery. Methods This prospective, single-center, single-arm study enrolled patients who were undergoing aortic reoperation and who had BioGlue used during previous aortic surgery. Histopathological assessment of aortic specimens obtained intraoperatively was performed on tissue that would have been removed independent of subject participation in the study. Results A total of 11 patients were enrolled and based on gross assessment, excessive amounts of BioGlue had been applied during the initial surgery in 36.4% of cases. The samples with the greatest amount of residual BioGlue demonstrated moderate to marked inflammatory responses, while the remaining samples demonstrated minimal to moderate inflammatory responses. Calcification of residual BioGlue was noted in 4 cases. Substantial medial degeneration was associated with suture line dehiscence in 4 cases, some of which had a large quantity of residual BioGlue. No evidence of suture degradation was observed. Conclusions Cases with surgical anastomosis dehiscence were associated with substantial medial degeneration. While no histologic findings directly linked BioGlue to these degenerative changes, a contributory role cannot be excluded. Following the manufacturer's instructions for appropriate application of BioGlue is crucial to prevent potential complications.

Currently, guidelines 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 on heart transplant (HT) outcomes.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 were calculated. Patients were partitioned into quintiles in terms of pHM ratio: undersizing 2, undersizing 1, reference, oversizing 1, and oversizing 2, with mean pHM donor-recipient ratio of 0.81, 0.96, 1.04, 1.12, and 1.28, respectively. Severe early graft failure and 30-day, 90-day, 1-year, and 10-year mortality were analyzed as outcomes.Recipients of the most oversized group were mostly female (P.001), had higher preoperative pulmonary vascular resistance (P = .009), had higher rate of mechanical circulatory support (P.05), and showed a lower United Network for Organ Sharing score (P = .041); the respective donors were younger and more frequently male (P = .001). Ischemic time was similar in all groups (P = .358). Pulmonary vascular resistance (P = .023; odds ratio [OR], 2.38), preoperative mechanical circulatory support (P = .05; OR, 3.06), and United Network for Organ Sharing score (P = .033; OR, 1.76) were identified as risk factors for early mortality. Donor-recipient pHM ratio did not impact early graft failure (P = .871) and early mortality (P = .526). Survival analysis after adjustment for pHM ratio subgroups did not show any difference in outcomes.A wide range of pHM ratios seems to be safe. A careful allocation of organs, by considering a pHM ratio mismatch, may balance rescue preoperative clinical profiles and preserve HT outcomes.

Traumatic brain injury (TBI) and blunt thoracic aortic injury (BTAI) are the top two leading causes of death after blunt force trauma. Patients presenting with concomitant BTAI and TBI pose a specific challenge with respect to management strategy, because the optimal hemodynamic parameters are conflicting between the two pathologies. Early thoracic endovascular aortic repair (TEVAR) is often performed, even for minimal aortic injuries, to allow for the higher blood pressure parameters required for TBI management. However, the optimal timing of TEVAR for the treatment of BTAI in patients with concomitant TBI remains an active matter of controversy.The Aortic Trauma Foundation international prospective multicenter registry was used to identify all patients who had undergone TEVAR for BTAI in the setting of TBI from 2015 to 2020. The primary outcomes included delayed ischemic or hemorrhagic stroke, in-hospital mortality, and aortic-related mortality. The outcomes were examined among patients who had undergone TEVAR at emergent (6 vs ≥6 hours) or urgent (24 vs ≥24 hours) intervals.A total of 100 patients (median age, 43 years; 79% men; median injury severity score, 41) with BTAI (Society for Vascular Surgery BTAI grade 1, 3%; grade 2, 10%; grade 3, 78%; grade 4, 9%) and concomitant TBI who had undergone TEVAR were identified. Emergent repair was performed for 51 patients (51%). Comparing emergent repair (6 hours) to urgent repair (≥6 hours), no difference was found in delayed cerebral ischemic events (2.0% vs 4.1%; P = .614), in-hospital mortality (15.7% vs 22.4%; P = .389), or aortic-related mortality (2.0% vs 2.0%; P = .996) and no patient had experienced delayed hemorrhagic stroke. Likewise, repairs conducted in an urgent (24 hours) setting showed no differences compared with those completed in an emergent (≥24 hours) setting regarding delayed ischemic stroke (2.6% vs 4.3%; P = .548), in-hospital mortality (18.2% vs 21.7%; P = .764), or aortic-related mortality (1.3% vs 4.3%; P = .654), and no patient had experienced delayed hemorrhagic stroke.In contrast to prior retrospective efforts, results from the Aortic Trauma Foundation international prospective multicenter registry have demonstrated that neither emergent nor urgent TEVAR for patients with concomitant BTAI and TBI was associated with delayed stroke, in-hospital mortality, or aortic-related mortality. In these patients, the timing of TEVAR did not have an effect on the outcomes. Therefore, the decision to intervene should be guided by individual patient factors rather than surgical timing.

OBJECTIVES We sought to examine management and outcomes of (Stanford) type A aortic dissection (TAAAD) in patients aged >70 years. METHODS All patients with TAAAD enrolled in the International Registry of Acute Aortic Dissection database (1996–2018) were studied (n = 5553). Patients were stratified by age and therapeutic strategy. Outcomes for octogenarians were compared with those for septuagenarians. Variables associated with in-hospital mortality were identified by multivariable logistic regression. RESULTS In-hospital mortality for all patients (all ages) was 19.7% (1167 deaths), 16.1% after surgical intervention vs 52.1% for medical management (P 80 years. Fewer octogenarians underwent surgery versus septuagenarians (68.1% vs 85.9%, P CONCLUSIONS When compared with septuagenarians, a smaller percentage of octogenarians undergo surgical repair for TAAAD, even though postoperative outcomes are similar. Age alone should not preclude consideration for surgery in appropriately selected patients with TAAAD.

Aim of this retrospective, multicenter study was to evaluate early and mid-term clinical and hemodynamic results of patients who underwent surgical aortic valve replacement (SAVR) with Intuity rapid-deployment bioprostheses (RDB) (Edwards Lifesciences, Irvine, CA). We analyzed data from the Italian Registry of Intuity Valve (INTU-ITA registry) that is a national, real-world and independent from the industry registry. Preoperative variables were defined according to EuroSCORE and postoperative outcomes according to Valve Academic Research Consortium (VARC). Survival distribution was evaluated using the Kaplan-Meier approach. A Cox-Proportional Hazard Model was employed to assess the effect of the covariates on patients’ survival. The registry included 1687 patients from 23 centers (June 2012-September 2019). Aortic cross clamp time for isolated SAVR was 55 minutes (IQR: 45–70 minute). Postoperative pace-maker rate was 6.3%. At discharge transaortic peak and mean gradients were: 18 mm Hg (IQR: 14–23 mm Hg) and 10 mmHg (IQR: 8–13 mm Hg), respectively. Indexed effective orifice area was 1.10 cm2/m2 (IQR: 0.91–1.31 cm2/m2) and the incidence of severe patient-prosthesis mismatch was 0.6%. Hemodynamic data for all valve sizes remained stable during follow-up. Thirty-day overall mortality was 1.8% (30 patients), and at follow-up it was 5.3% (89 patients). Kaplan-Meier overall survival was 95.5% (94.3–96.7%); 90.7% (88.3–93.1%); 86.4% (82.6–90.4%) at 1, 3, and 5 years, respectively. Serum creatinine (HR: 1.36; 95%CI: 1.04–1.81; p = 0.0397) and cross-clamp time (HR: 1.01; 95%CI: 1.002–1.017; p = 0.0077) were identified as independent predictors of mortality. According to our data from the INTU-ITA registry, SAVR with RDB provides good early clinical and hemodynamic results that are confirmed at follow-up.

Revascularization of the left subclavian artery (LSA) is considered a method of spinal cord protection from ischemia during thoracic endovascular aortic repair (TEVAR). Coverage of the artery of Adamkiewicz with TEVAR is usually well tolerated because of collateral pathways to this vessel, but on the other side, the LSA is crucial in this regard since it represents the primary source of collateral pathways. In our commentary, we wish to focus the discussion on the LSA revascularization and about the complexity of the anatomy of spinal cord supply in order to underline what have been already studied, analyzed, and recommended from the current guidelines.

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.

Aberrant right subclavian artery (ARSA) is a relatively rare congenital anomaly of the aortic arch. A 74-year-old woman was referred to our Cardiac Surgery Department for chest pain. Angio-CT scan showed an acute aortic dissection and revealed an ARSA routed behind the trachea. We performed supra-coronary ascending aorta and total arch replacement with Frozen Elephant Trunk (FET) technique. The ARSA was then termino-terminal anastomosed to one branch of the Thoraflex arch graft. Postoperative CT-scan indicated a successful reconstruction of the aortic arch, proving the open stent-grafting technique as a useful and effective approach for aortic disease with ARSA.

A 57-year-old man with severe aortic valve stenosis at high surgical risk underwent transcatheter valve replacement with a 29-mm Edwards Sapien-3 valve (Edwards Lifesciences). The valve was successfully implanted using the right femoral access, but at the end of the deployment the balloon ruptured (Videos 1 and 2) and could not be retrieved from the e-Sheath. The Commander delivery system was then readvanced in the aorta over the wire (Video 3), which was snared and externalized using a 25-mm AndraSnare (Andramed GmbH) inserted through the left femoral artery using a 25-cm-long 22-F Cook sheath (Cook Medical) (Figure 1). Then, the Commander was pushed over the wire, across the aortic bifurcation, making the ruptured balloon get into the Cook sheath (Figure 2). The Commander was then truncated (Figure 3), and the ruptured balloon proximal part attached to the pusher/balloon catheter unit was retrieved through the eSheath (Figure 4). Then, the ruptured balloon distal part attached to the inner balloon shaft was pushed forward such that it could be externalized through the left femoral sheath, cut (Figure 5), and finally pulled back with the wire through the eSheath (Figure 6).

Objectives The introduction of selective antegrade cerebral perfusion technique as method of cerebral protection improved the outcome of open arch surgery. The aim of this study was to report early outcomes using this technique. Methods Between 1997 and 2017, data were collected retrospectively for all patients who underwent surgical replacement of the aortic arch using selective antegrade cerebral perfusion ( n = 938). To confirm the effectiveness of this cerebral protection method, early outcome and results were evaluated. Results The incidence of postoperative permanent neurological dysfunction was 6.4%. Overall hospital mortality was 11.9% ( n = 112). On multivariable analysis, age >75 years, female gender, euroscore at increment of 1 point, chronic renal failure, extension of thoracic aorta replacement and CPB time emerged as independent risk factors for hospital mortality. The mid-term survival at 1, 5, 10 and 15 years was 92%, 78%, 60% and 49%, respectively. The competing risk analysis for permanent neurological dysfunction and aortic reoperations was performed excluding the patients who died during the hospital stay. The cumulative incidence of permanent neurological dysfunction and aortic reoperations was 2% at 3 years, 3% at 5 years, 6% at 10 years, 12% at 3 years, 15% at 5 years and 19% at 10 years, respectively. Conclusions From the early 90s to the present day, the selective antegrade cerebral perfusion has confirmed to be a useful and “safe” method of brain protection in aortic arch surgery in terms of postoperative neurological complications.

Approximately one-quarter of patients with acute type A aortic dissection (TAAD) present with concomitant malperfusion of coronary arteries, mesenteric circulation, lower extremities, kidneys, brain, and/or coma. It is generally accepted that TAAD patients who present with malperfusion experience higher mortality rates than patients without, although how specific malperfusion syndromes, alone or in combination, affect mortality is not well described.The International Registry of Acute Aortic Dissection database was queried for patients who underwent surgical repair of TAAD. Patients were stratified according to the presence/absence of malperfusion at presentation. Multivariable logistic regression was used to evaluate in-hospital mortality according to malperfusion type. Kaplan-Meier estimates were used to estimate 30-day postoperative survival.Six thousand four hundred thirty-seven patients underwent surgical repair of acute TAAD, of whom 2642 (41%) had 1 or more preoperative malperfusion syndromes. Mesenteric malperfusion (adjusted odds ratio [AOR], 4.84; P .001) was associated with the highest odds of in-hospital mortality, followed by coma (AOR, 1.88; P = .007), limb ischemia (AOR, 1.73; P = .008), and coronary malperfusion (AOR, 1.51; P = .02). Renal malperfusion (AOR, 1.37; P = .24) and neurologic deficit (AOR, 1.35; P = .28) were not associated with increased in-hospital mortality. In patients who survived to discharge, there was no difference in 1-year postdischarge survival in the malperfusion and no malperfusion cohorts (P = .36).Survival during the index admission after TAAD repair varies according to the presence and type of malperfusion syndromes, with mesenteric malperfusion being associated with the highest odds of in-hospital death. Not only the presence of malperfusion but rather specific malperfusion syndromes should be considered when assessing a patient's risk of undergoing TAAD repair.

Background: To share the results of a web-based expert panel discussion focusing on the management of acute and chronic aortic disease during the coronavirus (COVID-19) pandemic. Methods: A web-based expert panel discussion on April 18, 2020, where eight experts were invited to share their experience with COVID-19 disease touching several aspects of aortic medicine. After each talk, specific questions were asked by the online audience, and results were immediately evaluated and shared with faculty and participants. Results: As of April 18, 73.3% answered that more than 200 patients have been treated at their respective settings. Sixty-four percent were reported that their hospital was well prepared for the pandemic. In 57.7%, the percentage of infected healthcare professionals was below 5% whereas 19.2% reported the percentage to be between 10% and 20%. Sixty-seven percent reported the application of extracorporeal membrane oxygenationin less than 2% of COVID-19 patients whereas 11.8% reported application in 5%–10% of COVID-19 patients. Thirty percent of participants reported the occurrence of pulmonary embolism in COVID-19 patients. Three percent reported to have seen aortic ruptures in primarily elective patients having been postponed because of the anticipated need to provide sufficient ICU capacity because of the pandemic. Nearly70% reported a decrease in acute aortic syndrome referrals since the start of the pandemic. Conclusion: The current COVID-19 pandemic has—besides the stoppage of elective referrals—also led to a decrease of referrals of acute aortic syndromes in many settings. The reluctance of patients seeking medical help seems to be a major driver. The number of patients, who have been postponed due to the provisioning of ICU resources but having experienced aortic rupture in the waiting period, is still low. Further, studies are needed to learn more about the influence that the COVID-19 pandemic has on the treatment of patients with acute and chronic aortic disease.

Background The aim of the present study was to evaluate early results of thoracic endovascular aortic repair (TEVAR) using the Valiant Navion™ stent graft in a “real-world” scenario. Methods All patients who underwent TEVAR with the Valiant Navion™ endograft between November 2018 and November 2019 were included in this retrospective multicenter study (six European centers). The primary endpoints were technical success, incidence of major adverse events (MAEs), access failure, deployment failure, deployment accuracy, and rate of intraoperative endoleaks (ELs). Results One hundred-sixteen patients with varying thoracic aortic diseases were included. Eighteen patients (15.5%) were treated for an off-label condition. The technical success rate was 100%, without any access or deployment failures. The proximal and distal deployment accuracy rates were 99.1% and 97.4%, respectively. There were no intraoperative MAEs, including death. Two (1.7%) type Ib ELs were detected at the first postoperative CTA, all of which were in off-label procedures and related to the short length of the sealing neck. No type III ELs were detected. The median hospitalization time was 8 days (IQR 4–12), including a median intensive care unit stay of 1 day (IQR 1–2). The in-hospital mortality rate was 4.3%. At a median follow-up time of 98 days (IQR 39–187), there were no aortic-related mortalities or new onset of endoleaks. Conclusion Our initial experience with the Valiant Navion™ endograft in a wide variety of aortic diseases showed safe early outcomes, especially for on-label procedures.

IgG4-related aortitis is an inflammatory condition of the aorta, characterized by aortic wall thickening and periaortic soft-tissue involvement. Therefore, this condition can mimic an aortic intramural hematoma (IMH), due to similar radiological findings. We hereby report the case of an IgG4-related aortitis misdiagnosed as an IMH, associated with cerebral hemorrhage, possibly due to cerebral vascular system involvement.

The study objective was to analyze the outcomes of reoperative thoracic aortic surgery at our institution from January 1986 to December 2018 to identify specific risk factors for early and late mortality.Two groups of patients were identified: aortic root or ascending aorta repair (group 1: proximal repair, 218 patients, 48%) and arch surgery or descending thoracic aorta repair (group 2: distal repair, 235 patients, 52%). Primary end points were 30-day mortality, 10-year survival, and freedom from aortic reoperations.The 30-day mortality (6.4% vs 8.1%) and in-hospital mortality (8.3% vs 11.9%) were similar (P .05) in the 2 groups. Multivariable analysis identified female gender (odds ratio, 8.60, P .01), endocarditis (odds ratio, 2.96, P = .04), and cardiopulmonary bypass time (odds ratio, 1.02, P .01) as risk factors for 30-day mortality. Mean follow-up time was 163 months (confidence interval, 147-179). Long-term survival at 1, 5, and 10 years was 91.2%, 79.4%, and 66.3% in the proximal repair group and 80.7%, 68.8%, the and 55.3% in distal repair group, respectively (P = .03). According to the indication, 1-, 5-, and 10-year survivals were 92.1%, 82.3%, and 68.8% in degenerative aneurysms; 82.7%, 72.4%, and 56.3% in residual dissections; 80.9%, 65.4%, and 50.3% in endocarditis and pseudoaneurysms; 69.2%, 52.7%, and 42.2% in acute type A aortic dissections, respectively (P .01). Competing risk analysis showed a significantly different cumulative incidence of reoperation at 1, 5, and 10 years between the 2 groups: 0.50%, 0.50%, and 0.90%, respectively, for the proximal repair group, and 0.40%, 4.30%, and 7.70%, respectively, the for distal repair group (P .01).In our experience, short- and long-term results of reoperative thoracic aortic surgery were satisfactory in chronic aneurysms but poor in aortic dissections, pseudoaneurysms, and active endocarditis. Reoperative aortic surgery carries a high risk, regardless of the anatomic extension of the procedure.

Background: The aim of this multicenter prospective study was to evaluate the prognostic weight of preoperative right ventricular assessment on early mortality in cardiac surgery. Methods: This is a multicenter prospective observational study performed by the Italian Group of Research for Outcome in Cardiac Surgery (GIROC) including 11 centers. From October 2017 to March 2019, out of 923 patients undergoing cardiac surgery, 28 patients with some missing data were excluded and 895 patients were enrolled in the study right ventricular dilatation was defined as a basal end-diastolic diameter >42 mm. The right ventricle (RV) function was assessed using the combination of three parameters: fractional area changing (FAC), tricuspid annular plane systolic excursion (TAPSE), and S'-wave using tissue Doppler imaging (TDI-S'); RV dysfunction was defined as the presence of at least two of the following cutoffs: FAC

The formation of postaortic coarctation aneurysms (pCoAA) is well-described in the literature and carries a significant risk of rupture and death. Treatment strategies include open surgical, hybrid, and endovascular repair, depending on the clinical presentation, risk assessment, and anatomy. The aim of this study was to report the early and midterm results of open surgical and endovascular repair of pCoAA.This is an international multicenter retrospective study including patients who underwent open surgical or endovascular repair for pCoAA between 2000 and 2021 at 14 highly specialized academic cardiovascular centers. The preoperative, intraoperative, and postoperative data were recorded and analyzed.A total of 74 patients (46 male; median age, 44 years; interquartile range [IQR], 35-53 years) underwent pCoAA repair. All patients had previously undergone surgical repair of aortic coarctation at a median age of 11 years for the index procedure (IQR, 7-17 years). The most common first surgical correction was synthetic patch aortoplasty in 48 patients, followed by graft interposition in 11. The median pCoAA diameter was 54 mm (IQR, 44-63 mm). The median time from the aortic coarctation repair to the pCoAA diagnosis was 33 years (IQR, 25-40 years). A total of 33 patients had symptoms at presentation, including thoracic or back pain in 8 patients. Open surgical repair was performed in 28 patients, including four frozen elephant trunk procedures and one Bentall. The remaining 46 patients underwent endovascular repair of the pCoAA. Two in-hospital deaths were observed (one frozen elephant trunk and one endovascular). After a median follow-up of 50 months (IQR, 14-127 months), there were a total of seven reinterventions.This international multicenter study demonstrates that patients with pCoAA can be safely treated with either open surgical or endovascular interventions. Because the median time between the coarctation repair and the aneurysm formation was more than 30 years, life-long surveillance of these patients is warranted.

AIMS: To compare early and late mortality of acute isolated tricuspid valve infective endocarditis (TVIE) treated with valve repair or replacement.METHODS: Patients who were surgically treated for TVIE from 1983 to 2018 were retrieved from the Italian Registry for Surgical Treatment of Valve and Prosthesis Infective Endocarditis. All the patients were followed up by means of phone interview or calling patient referral physicians or cardiologists. Kaplan-Meier method was used to assess late survival and survival free from TVIE recurrence with log-rank test for univariate comparison. The primary end points were early mortality (30 days after surgery) and long-term survival free from TVIE recurrence.RESULTS: A total of 4084 patients were included in the registry. Among them, 149 patients were included in the study. Overall, 77 (51.7%) underwent TV repair and 72 (48.3%) TV replacement. Early mortality was 9% (13 patients). Expected early mortality according to EndoSCORE was 12%. The TV repair showed lower mortality and major complication rate (7% and 16%), compared with TV replacement (11% and 25%), but statistical significance was not reached. Median follow-up was 19.1 years (14.3-23.8). Late deaths were 30 and IE recurrences were 5. No difference in cardiac survival free from IE was found between the two groups after 20 years (80 ± 6% Repair Group vs 59 ± 13% Replacement Group, P = 0.3).CONCLUSIONS: Overall results indicate that once surgically addressed, TVIE has a low recurrence rate and excellent survival, apparently regardless of the type of surgery used to treat it.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare disease with a very complex pathophysiology differing from other causes of pulmonary hypertension (PH). It is an infrequent consequence of acute pulmonary embolism that is frequently misdiagnosed. Pathogenesis has been related to coagulation abnormalities, infection or inflammation, although these disturbances can be absent in many cases. The hallmarks of CTEPH are thrombotic occlusion of pulmonary vessels, variable degree of ventricular dysfunction and secondary microvascular arteriopathy. The definition of CTEPH also includes an increase in mean pulmonary arterial pressure of more than 25 mmHg with a normal pulmonary capillary wedge of less than 15 mmHg. It is classified as World Health Organization group 4 PH, and is the only type that can be surgically cured by pulmonary endarterectomy (PEA). This operation needs to be carried out by a team with strong expertise, from the diagnostic and decisional pathway to the operation itself. However, because the disease has a very heterogeneous phenotype in terms of anatomy, degree of PH and the lack of a standard patient profile, not all cases of CTEPH can be treated by PEA. As a result, PH-directed medical therapy traditionally used for the other types of PH has been proposed and is utilized in CTEPH patients. Since 2015, we have been witnessing the rebirth of balloon pulmonary angioplasty, a technique first performed in 2001 but has since fallen out fashion due to major complications. The refinement of such techniques has allowed its safe utilization as a salvage therapy in inoperable patients. In the present keynote lecture, we will describe these therapeutic approaches and results.

Background: Orthotopic heart transplantation (OHT) remains the gold standard for the treatment of end-stage heart failure. The number of patients who have had at least one prior sternotomy while awaiting transplantation has increased over the years reaching 50% in the last ISHLT registry report. We analysed our institutional transplant activity focusing on prior-sternotomy setting to identify the real burden of this preoperative variable and its potential consequences. Methods: Between 2000 and 2020, a total of 512 consecutive adult patients underwent OHT. We divided them into two groups according to the previous sternotomy variable: a prior sternotomy group (PS-group, n = 131, 25.6%) and a heart transplant as first sternotomy group (FS-group, n = 381, 74.4%). After propensity score matching, a total of 106 matched-pairs were identified for the final analysis. Results: The overall 30-day mortality was similar in the two groups (7.5% vs. 5.7%, p =.58). The prior sternotomy was not an independent risk factor for 90-day mortality (odds ratio: 0.89, p =.81). In the matched sample, prior cardiac surgery was not predictive for any major postoperative complication: primary graft failure, AKI, bleeding, acute respiratory insufficiency, need for extra-corporeal life support (p >.05). The log-rank test revealed no significant difference between the two groups in the unmatched and matched pools (p =.93 and 0.69 respectively. At univariable analysis prior sternotomy was not associated with an increased risk of posttransplant mortality (hazard ratio: 0.87, p =.599). Conclusions: Despite it increases surgical complexity, the reoperation alone does not represent a proper risk factor and among different co-variates that may affect post-OHT outcomes.

Background/Introduction Different types of bio-prosthesis are now available for the treatment of aortic valve disease. In absence of the “ideal” heart valve prosthesis, the best choice may be customized on the basis of the patient's profile. Purpose The aim of this study was to compare results in different subgroups of bio-prosthesis in elderly patients (>75 years old) undergoing conventional or surgical trans-catheter aortic valve replacement (AVR). Primary outcome was all cause mortality, secondary outcomes were: early post-operative complications (stroke, AV-block, acute kidney injury requiring temporary dialysis), freedom from structural vascular disease (SVD) and from re-operation. Methods In this retrospective study we analysed 1202 patients over 75 years old, underwent AVR from 2002 to 2018. Inclusion criteria were: age >75 years underwent AVR; we divided our population in 3 groups according to different strategy: primary aortic valve replacement with sutured (group 1, n=1005), sutureless (group 2, n=103) or surgical trans-catheter aortic valve replacement (group 3, n=94). Exclusion criteria: concomitant cardiac procedure other than coronary artery by-pass graft (CABG) or endocarditis. Patient and disease characteristics are described as numbers and percentages, continuous data were expressed using mean and standard deviation. Differences between groups were evaluated using either Student t-test or Mann-Whitney U test or ANOVA test. Survival curves of the primary outcome and freedom from secondary outcomes were built with the Kaplan-Meier method. Results The mean age of the overall population was 80.5±3.6 years with a mean STS score of assessed at 2.79±2.2% (2.27±1.0 for standard AVR, 3.3±2.2% for sutureless and 6.4±4.5 for S-TAVR, p-value Conclusion(s) The outcomes of surgical AVR in a elderly population could be safely guaranteed with different biological prosthesis and operative techniques. A patient tailored approach should be always advised to improve current available transcatheter options. Funding Acknowledgement Type of funding sources: None. Figure 1Figure 2
