RESUMO
OBJECTIVE: Evaluate days alive and out of the hospital (DAOH) as an outcome measure after orthotopic heart transplantation in patients with mechanical circulatory support (MCS) as a bridge to transplant compared to those patients without prior MCS. DESIGN: A retrospective observational study of adult patients who underwent cardiac transplantation between January 1, 2015, and January 1, 2020. The primary outcome was DAOH at 365 days (DAOH365) after an orthotopic heart transplant. A Poisson regression model was fitted to detect the association between independent variables and DAOH365. SETTING: An academic tertiary referral center. PARTICIPANTS: A total of 235 heart transplant patients were included-103 MCS as a bridge to transplant patients, and 132 direct orthotopic heart transplants without prior MCS. MEASUREMENTS AND MAIN RESULTS: The median DAOH365 for the entire cohort was 348 days (IQR 335.0-354.0). There was no difference in DAOH365 between the MCS patients and patients without MCS (347.0 days [IQR 336.0-353.0] v 348.0 days [IQR 334.0-354.0], p = 0.43). Multivariate analysis identified patients who underwent a transplant after the 2018 heart transplant allocation change, pretransplant pulmonary hypertension, and increased total ischemic time as predictors of reduced DAOH365. CONCLUSIONS: In this analysis of patients undergoing orthotopic heart transplantation, there was no significant difference in DAOH365 in patients with prior MCS as a bridge to transplant compared to those without MCS. Incorporating days alive and out of the hospital into the pre-transplant evaluation may improve understanding and conceptualization of the post-transplantation patient experience and aid in shared decision-making with clinicians.

Extracorporeal life support, commonly referred to as extracorporeal membrane oxygenation (ECMO), is indicated when conventional medical and surgical measures fail to support a patient during cardiac or respiratory failure. Increased use of ECMO in recent years has led to innovation that has improved safety in appropriate candidates. This has resulted in the application of novel approaches to complex surgical problems. Herein, we describe a simple, novel, and new-to-market ECMO circuit used for successful perioperative veno-venous ECMO support of a patient undergoing complex repair of a tracheoesophageal fistula. We believe that this circuit and its use for intra-and post-operative extracorporeal support provides a framework for safe and simple ECMO support in the future, including perioperative support for patients undergoing complicated and challenging thoracic procedures.

A previously healthy 49-year-old male patient presented with COVID-19 infection and required mechanical ventilation and extracorporeal membrane oxygenation due to severe hypoxemia. Echocardiography showed cardiac dysfunction with an apical sparing strain pattern, which rapidly normalized within a week. Apical sparing myocardial strain in patients with COVID-19 infection may suggest reverse-type stress cardiomyopathy.

OBJECTIVES: Left ventricular (LV) septal hypertrophy in aortic stenosis raises diagnostic and therapeutic questions. However, the etiology and clinical consequences of this finding have not been well studied. The aim of this study was to perform a morphologic evaluation of the LV in aortic stenosis and to investigate the contributing factors and consequences of septal hypertrophy. METHODS: Patients with moderate or severe aortic stenosis were prospectively enrolled. Patients with previous myocardial infarction, wall motion abnormalities, at least moderate valvular regurgitation, known cardiomyopathy, an LV ejection fraction of less than 50%, and age younger than 65 years were excluded. RESULTS: Forty-one patients underwent a final analysis. Septal hypertrophy (LV septal wall thickness ≥15 mm) was confirmed in 21 of 41 patients. The septal hypertrophy group had higher peak aortic valve velocity, a higher diabetes mellitus rate, and a higher rate and longer duration of hypertension than those without septal hypertrophy. The peak aortic valve velocity (odds ratio, 7.1; 95% confidence interval, 1.4-37.1) and diabetes mellitus (odds ratio, 7.4; 95% confidence interval, 1.2-46.2) were the significant factors associated with septal hypertrophy by multivariate analysis. Intraventricular conduction disturbance on electrocardiography was more frequent in the septal hypertrophy group (P = .021). CONCLUSIONS: Left ventricular septal hypertrophy was commonly observed in elderly patients with aortic stenosis, and a higher aortic valve velocity, hypertension, and diabetes mellitus were associated factors. Intraventricular conduction disturbance occurred more often in patients with septal hypertrophy than those without, which implies the pathophysiologic consequence. Further studies are needed to determine the impact of septal hypertrophy and intraventricular conduction disturbance on the prognosis of patients after aortic valve interventions.

Extracorporeal membrane oxygenation (ECMO) is indicated when conventional measures fail to support a patient during cardiac or respiratory failure. Due to the complicated nature of ECMO, patients often require transport to a tertiary care center. This study retrospectively compared the performance of the Cardiohelp™ (Maquet) life support system with a previously used ECMO circuit when transporting adult patients on venoarterial ECMO between facilities. Two ECMO circuits were compared for performance: 1) the Cardiohelp™ (Maquet) life support system and 2) the "standard" circuit consisting of a Thoratec CentriMag centrifugal pump, Maquet Quadrox-D oxygenator, and a Terumo CDI-500 in-line blood gas analyzer. After analyzing data from 16 patients (eight patients supported with each ECMO system), no differences in patient demographics, percentage of patients successfully weaned from ECMO, percentage of patients surviving to discharge, duration supported on the initial ECMO system, or total duration of ECMO were noted. No patient deaths were related to circuit failure or circuit disruptions in either group. Analysis of the performance of the ECMO circuits and the resulting patient status showed few significant differences between ECMO groups (Cardiohelp™ vs. standard circuit) and time points (the first 8 hours vs. a 24-hour time point). The statistically significant differences were not concerning in terms of appropriate medical support or patient safety. Of interest, the transmembrane pressure was significantly lower for the Cardiohelp™ module vs. the standard oxygenator during the first 8 hours (20.1 [5.3] vs. 37.1 [7.1] mmHg; p < .001) and at 24 hours (21.3 [3.8] vs. 34.8 [7.9] mmHg; p = .001). The Cardiohelp™ portable life support system provides safe and reliable support for adult patients on ECMO during interhospital patient transport as compared to the standard circuit.

OBJECTIVE: The selection of valve prostheses for patients undergoing surgical aortic valve replacement remains controversial. In this study, we compared the long-term outcomes of patients undergoing aortic valve replacement with biological or mechanical aortic valve prostheses. METHODS: We evaluated late results among 5762 patients aged 45 to 74 years who underwent biological or mechanical aortic valve replacement with or without concomitant coronary artery bypass from 1989 to 2019 at 4 medical centers. The Cox proportional hazards model was used to compare late survival; the age-dependent effect of prosthesis type on long-term survival was evaluated by an interaction term between age and prosthesis type. Incidences of stroke, major bleeding, and reoperation on the aortic valve after the index procedure were compared between prosthesis groups. RESULTS: Overall, 61% (n = 3508) of patients received a bioprosthesis. The 30-day mortality rate was 1.7% (n = 58) in the bioprosthesis group and 1.5% (n = 34) in the mechanical group (P = .75). During a mean follow-up of 9.0 years, the adjusted risk of mortality was higher in the bioprosthesis group (hazard ratio, 1.30, P < .001). The long-term survival benefit associated with mechanical prosthesis persisted until 70 years of age. Bioprosthesis (vs mechanical prosthesis) was associated with a similar risk of stroke (P = .20), lower risk of major bleeding (P < .001), and higher risk of reoperation (P < .001). CONCLUSIONS: Compared with bioprostheses, mechanical aortic valves are associated with a lower adjusted risk of long-term mortality in patients aged 70 years or less. Patients aged less than 70 years undergoing surgical aortic valve replacement should be informed of the potential survival benefit of mechanical valve substitutes.
RESUMO
UNLABELLED: A challenging aspect of managing patients on venoarterial extracorporeal membrane oxygenation (V-A ECMO) is a thorough understanding of the relationship between oxygenated blood from the ECMO circuit and blood being pumped from the patient's native heart. We present an adult V-A ECMO case report, which illustrates a unique encounter with the concept of "dual circulations." Despite blood gases from the ECMO arterial line showing respiratory acidosis, this patient with cardiogenic shock demonstrated regional respiratory alkalosis when blood was sampled from the right radial arterial line. In response, a sample was obtained from the left radial arterial line, which mimicked the ECMO arterial blood but was dramatically different from the blood sampled from the right radial arterial line. A retrospective analysis of patient data revealed that the mismatch of blood gas values in this patient corresponded to an increased pulse pressure. Having three arterial blood sampling sites and data on the patient's pulse pressure provided a dynamic view of blood mixing and guided proper management, which contributed to a successful patient outcome that otherwise may not have occurred. As a result of this unique encounter, we created and distributed graphics representing the concept of "dual circulations" to facilitate the education of ECMO specialists at our institution. KEYWORDS: ECMO, education, cardiopulmonary bypass, cannulation.

In most cases, acute mitral valve regurgitation in the setting of infective endocarditis is caused by the destruction of either the mitral valve leaflets or the chordal apparatus. A 54-year-old woman had development of respiratory failure due to pulmonary oedema from severe acute mitral valve regurgitation in the setting of acute bacterial endocarditis. She was found to have a ruptured anterolateral papillary muscle from occlusion of the circumflex artery by embolic vegetations arising from the aortic valve. Although this occurrence is uncommon, an embolic phenomenon resulting in myocardial infarction and subsequent rupture of papillary muscle must be considered as a cause of acute severe mitral valve regurgitation.

The intrinsic and extrinsic activation pathways of the hemostatic system converge when prothrombin is converted to thrombin. The ability to generate an adequate thrombin burst is the most central aspect of the coagulation cascade. The thrombin-generating potential in patients following cardiopulmonary bypass (CPB) may be indicative of their hemostatic status. In this report, thrombography, a unique technique for directly measuring the potential of patients' blood samples to generate adequate thrombin bursts, is used to characterize the coagulopathic profile in post-CPB patients. Post-CPB hemostasis is typically achieved with protamine reversal of heparin anticoagulation and occasionally supplemented with blood product component transfusions. In this pilot study, platelet poor plasma samples were derived from 11 primary cardiac surgery patients at five time points: prior to CPB, immediately post-protamine, upon arrival to the intensive care unit (ICU), 3 hours post-ICU admission, and 24 hours after ICU arrival. Thrombography revealed that the Endogenous Thrombin Potential (ETP) was not different between [Baseline] and [PostProtamine] but proceeded to deteriorate in the immediate postoperative period. At the [3HourPostICU] time point, the ETP was significantly lower than the [Baseline] values, 1233 +/- 591 versus 595 +/- 379 nM.min (mean +/- SD; n=9, p < .005), despite continued adequacy of hemostasis. ETPs returned to baseline values the day after surgery. Transfusions received, conventional blood coagulation testing results, and blood loss volumes are also presented. Despite adequate hemostasis, thrombography reveals an underlying coagulopathic process that could put some cardiac surgical patients at risk for postoperative bleeding. Thrombography is a novel technique that could be developed into a useful tool for perfusionists and physicians to identify coagulopathies and optimize blood management following CPB.

Interfacility transport of a critically ill patient with acute respiratory distress syndrome (ARDS) may be necessary for a higher level of care or initiation of extracorporeal membrane oxygenation (ECMO). During the COVID-19 pandemic, ECMO has been used for patients with severe ARDS with successful results. Transporting a patient after ECMO cannulation by the receiving facility brings forth logistic challenges, including availability of adequate personal protective equipment for the transport team and hospital capacity management issues. We report our designated ECMO transport team's experience of 5 patients with COVID-19-associated severe ARDS after cannulation at the referring facility. Focusing on transport-associated logistics, creation of checklists, and collaboration with emergency medical services partners is necessary for safe and good outcomes for patients while maintaining team safety.
RESUMO
BACKGROUND: Conventional transvenous approaches for implantable cardioverter defibrillator (ICD) lead placement are not possible in some patients with limited venous access or severe tricuspid valve dysfunction. METHODS: We retrospectively identified six patients who underwent ICD placement or revision requiring nontraditional alternative surgical lead placement at our institution between November 2006 and August 2008. The baseline and operative patient characteristic data were accumulated and reviewed. RESULTS: All the patients (mean age 71 +/- 3.4 years) underwent nontraditional surgical placement of epicardial ICD leads and traditional placement of ventricular epicardial bipolar pacing/sensing leads. Five patients had the distal lead tip fixed to the anterior epicardium of the right ventricular outflow tract, which was then looped under and around the ventricles, forming a "sling," and tunneled to a left subclavicular pocket. One patient had a single unipolar subcutaneous array lead fashioned into a "loop" and placed under the inferior aspect of the ventricles. The average procedure time was 311 +/- 115 minutes with a mean defibrillatory threshold (DFT) of < or = 22 + 3 J. Post-procedure hospitalization was 9.3 +/- 4.4 days and no device-related complications were encountered. Mean device follow-up of 451 + 330 days showed normal function and two appropriate successful ICD discharges. CONCLUSION: Nontraditional alternative surgical methods for the placement of ICD systems in adult patients with limited venous access or TV dysfunction can achieve results similar to those of conventionally placed endovascular leads with limited complications and comparable DFTs in short-term follow-up.

BACKGROUND: The objectives of this study were to describe opioid prescribing after hospitalization for elective cardiac operation, to identify factors associated with increased opioid prescriptions, and to develop procedure-specific opioid prescribing guidelines. METHODS: We analyzed data from all adults (≥18 years) undergoing elective cardiac operation for acquired heart disease from July 2014 to March 2017 at 3 affiliated hospitals. Opioid prescription data were abstracted and converted to morphine milligram equivalents (MME). Multivariable logistic regression was performed with the outcome of top-quartile prescriptions. RESULTS: There were 4145 study patients after exclusion of preoperative opioid users (10.5%). Mean ± SD patient age was 63.9 ± 13.2 years, and 68.4% (n = 2835) were male. The operation was the first in 87.3% (3617); the most common operative approach was sternotomy in 91.0% (n = 3773), followed by robot-assisted operation in 4.6% (n = 192). The majority of patients, 72.7%, received an opioid prescription at hospital dismissal, with a median opioid prescription of 200 MME (interquartile range 0 to 375 MME; range 0 to 6400 MME). This varied by hospital, with medians of 150, 450, and 600 MME (P < .001). On multivariable analysis, the factor with greatest association with top-quartile opioid prescription was hospital (odds ratio, 57.2, highest vs lowest; 95% confidence interval, 40.2-81.4; P < .001). CONCLUSIONS: Significant variation in opioid prescribing practices after cardiac operation was observed. The primary driver was hospital-centric as opposed to patient specific. Opioid prescribing guidelines were established to standardize posthospital pain management.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a reliable method of treating patients with severe aortic stenosis, but is associated with postprocedure conduction defects. OBJECTIVE: The purpose of this study was to compare clinical outcomes in patients who developed advanced conduction defects post-TAVR to those who did not. METHODS: We conducted a retrospective chart review of 243 patients who underwent balloon-expandable TAVR with the Edwards Sapien valve to determine the incidence of advanced conduction defects in our cohort. We compared clinical outcomes including overall mortality, improvement in symptomatology, and improvement in left ventricular ejection fraction. RESULTS: Among the 243 patients included in the study, 9.1% (22/243) required permanent pacemaker (PPM); 19.8% (48/243) developed left bundle branch block (LBBB), and 71.2% (173/243) did not develop any permanent advanced conduction defects. Overall 1-year mortality was similar across all three groups. There was significant improvement in New York Heart Association functional capacity of all groups post-TAVR, but this was much less in the PPM group (45.5% vs 68.8%, P = .04). Postprocedure from TAVR, patients with LBBB or PM were less likely to have improvement in their ejection fraction (net loss of -0.7% for LBBB and -5.7% for PPM compared to a net gain of 2.3% for no-LBBB/PM (P = .02). CONCLUSION: Patients who develop LBBB or require PM post-TAVR with Edwards Sapien valves are less likely to improve New York Heart Association functional capacity and more likely to have no improvement or deterioration of their pre-TAVR left ventricular ejection fraction.

BACKGROUND: The surgical and procedural specialties are continually evolving their methods to include more complex and technically difficult cases. These cases can be longer and incorporate multiple teams in a different model of operating room synergy. Patients are frequently older, with comorbidities adding to the complexity of these cases. Recording of this environment has become more feasible recently with advancement in video and audio capture systems often used in the simulation realm. AIMS: We began using live capture to record a new procedure shortly after starting these cases in our institution. This has provided continued assessment and evaluation of live procedures. The goal of this was to improve human factors and situational challenges by review and debriefing. SETTING AND DESIGN: B-Line Medical's LiveCapture video system was used to record successive transcatheter aortic valve replacement (TAVR) procedures in our cardiac catheterization/laboratory. An illustrative case is used to discuss analysis and debriefing of the case using this system. RESULTS AND CONCLUSIONS: An illustrative case is presented that resulted in long-term changes to our approach of these cases. The video capture documented rare events during one of our TAVR procedures. Analysis and debriefing led to definitive changes in our practice. While there are hurdles to the use of this technology in every institution, the role for the ongoing use of video capture, analysis, and debriefing may play an important role in the future of patient safety and human factors analysis in the operating environment.

Therapeutic radiotherapy rarely causes sarcoma, and this occurs years after completion of the intended treatment. In treating breast carcinoma, careful planning in the application of modern radiotherapeutic techniques usually can shield the heart and pericardium. We report a rare case of angiosarcoma of the pericardium, which presented in a 41-year-old woman as constrictive pericarditis 8 years after irradiation for cancer of the left breast. To our knowledge, this is only the 2nd report of angiosarcoma of the pericardium after radiotherapy.

INTRODUCTION: Advances in medical and surgical care have made it possible for an increasing number of patients with Congenital Heart disease (CHD) to live into adulthood. Transposition of the great vessels (TGV) is the most common cyanotic congenital cardiac disease where the right ventricle serves as systemic ventricle. It is not uncommon for these patients to have systemic ventricular failure requiring transplantation. STUDY DESIGN: Hemodynamic decompensation in these patients can be swift and difficult to manage. Increasingly percutaneous LVAD's such as the Impella (Abiomed, Mass, USA) are gaining popularity in these situations owing to their relative ease of placement, both in and outside of the operating room. CONCLUSION: In this paper we demonstrate that Impella (IMP) CP placement through the axillary artery approach shows to be suitable option for short term cardiac support and improvement of end organ perfusion in anticipation of cardiac transplantation.

Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients with severe aortic valve stenosis. Given the burden of valvular heart disease in the general population and the increasing numbers of patients who have had previous valve operations, we are now seeing a growing number of high-risk patients presenting with prosthetic valve stenosis, who are not potential surgical candidates. For this high-risk subset transcatheter valve delivery may be the only option. Here, we present an inoperable patient with severe, prosthetic valve aortic and mitral stenosis who was successfully treated with a trans catheter based approach, with a valve-in-valve implantation procedure of both aortic and mitral valves.

BACKGROUND: Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. METHODS: A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. RESULTS: Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p < 0.005) and operations (p < 0.005). The majority of consultations were for small bowel obstruction/ileus (n = 4, 17%), cholecystitis (n = 3, 13%) and to rule out ischemia (n = 2, 9%) CONCLUSIONS: In the era of modern critical care and cardiac surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

Coccidioidal pericarditis, an uncommonly diagnosed entity, may evolve to a constrictive process. Constrictive coccidioidal pericarditis requires pericardiectomy and antifungal therapy. In the elderly, pericardiectomy may be complicated by coagulopathy and septic shock. Despite potential toxicity, use of antifungal therapy early postoperatively offers the best chance for survival.
