RESUMO
Primary cardiac angiosarcoma is a rare, aggressive malignancy that commonly metastasizes to various organs. The presenting symptoms are typically nonspecific, so a comprehensive examination is required to confirm the diagnosis promptly. This case report describes the presentation of an older patient with a history of neoplasms. Echocardiography and biopsy were performed, but despite surgical intervention to resect a large right atrial mass, the patient died. A final diagnosis of primary angiosarcoma was made based on the resected specimen.

Introduction: Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 is a highly contagious viral disease. Cardiovascular diseases and heart failure elevate the risk of mechanical ventilation and fatal outcomes among COVID-19 patients, while COVID-19 itself increases the likelihood of adverse cardiovascular outcomes. Methods: We collected blood samples and clinical data from hospitalized cardiovascular patients with and without proven COVID-19 infection in the time period before the vaccine became available. Statistical correlation analysis and machine learning were used to evaluate and identify individual parameters that could predict the risk of needing mechanical ventilation and patient survival. Results: Our results confirmed that COVID-19 is associated with a severe outcome and identified increased levels of ferritin, fibrinogen, and platelets, as well as decreased levels of albumin, as having a negative impact on patient survival. Additionally, patients on ACE/ARB had a lower chance of dying or needing mechanical ventilation. The machine learning models revealed that ferritin, PCO2, and CRP were the most efficient combination of parameters for predicting survival, while the combination of albumin, fibrinogen, platelets, ALP, AB titer, and D-dimer was the most efficient for predicting the likelihood of requiring mechanical ventilation. Conclusion: We believe that creating an AI-based model that uses these patient parameters to predict the cardiovascular patient's risk of mortality, severe complications, and the need for mechanical ventilation would help healthcare providers with rapid triage and redistribution of medical services, with the goal of improving overall survival. The use of the most effective combination of parameters in our models could advance risk assessment and treatment planning among the general population of cardiovascular patients.
RESUMO
Physical therapy (PT) benefits for critically ill patients are well recognized; however, little data exist on PT in patients receiving temporary mechanical circulatory support. In this single-center retrospective study (February 2017-January 2022), we analyzed 37 patients who received an axillary Impella device (Abiomed, Danvers, MA) and PT to "prehabilitate" them before durable left ventricular assist device (dLVAD) implantation. The Activity Measure for Post-Acute Care (AM-PAC) Basic Mobility tool assessed the functional status at different points during admission. Immediately after Impella placement, the median AM-PAC score was 12.7 (interquartile range [IQR], 9-15), and the scores continued to significantly increase to 18.4 (IQR, 16-23) before dLVAD and up to 20.7 (IQR, 19-24) at discharge, indicating improved independence. No PT-related complications were reported. Thus, we hypothesize that critically ill patients initially deemed equivocal candidates may safely participate in PT while maximizing functional activities before dLVAD placement.

Background: Coronary lesions are supposed to be enclosed between proximal and distal reference segments (RSs), the sites with the largest lumens within the same vessel segment. Finding "healthy" landing zones has been fundamental for efficient stent implantation. Consequently, our study aimed to determine, using optical coherence tomography (OCT), to what degree RSs conform to this concept. Methods: Sixty-seven patients with a mean age of 63.5 years underwent culprit lesion stenting due to acute myocardial infarction (MI) (Group 1) or stable angina (Group 2). OCT was performed with commercially available equipment; all evaluations were made at RSs and minimal lumens. Results: Normal vessel wall was infrequent (~10%) at RSs. Acceptable external elastic 220°) occurred in 55% to 67% and in 28% to 31% of RSs, respectively. Tissue composition at RSs was similar in both study groups except for a greater accumulation of thin-cap fibroatheromas (TCFA) in acute MI (29% in Group 1 vs. 9% in Group 2, P=0.035). Flow deterioration after stenting was associated with TCFA clusters extending from culprit main bodies into proximal RSs (P=0.008). Conclusions: Optimal landing zones for stent placement should frequently be searched for beyond the culprit lesion segments although utilizing the largest intrasegmental lumens does not seem to cause immediate harm. However, TCFA at the landings should definitely be avoided.
RESUMO
Severe acute hypercapnia is independently associated with increased adverse effects and intensive care unit mortality in mechanically ventilated patients. During the severe acute respiratory syndrome coronavirus 2 (COVID-19) pandemic, some patients were placed on extracorporeal carbon dioxide removal support when extracorporeal membrane oxygenation (ECMO) support was at capacity or not offered. We present a patient with severe acute respiratory distress syndrome caused by COVID-19 pneumonia, who was supported with Hemolung Respiratory Assist System (ALung Technologies, Inc., LivaNova, Pittsburgh, PA) via the right subclavian vein as a bridge to lung transplantation after venovenous ECMO support. The patient survived and was discharged home.

Background: Extracorporeal membrane oxygenation (ECMO) has extended the survivability of critically ill patients beyond their unsupported prognosis and has widened the timeframe for making an informed decision about the goal of care. However, an extended time window for survival does not necessarily translate into a better outcome and the sustaining treatment is ultimately withdrawn in many patients. Emerging evidence has implicated the determining role of palliative care consult (PCC) in direction of the care that critically ill patients receive. Objective: To evaluate the impact of PCC in withdrawal of life-sustaining treatment (WOLST) among critically ill patients, who were placed on venovenous ECMO (VV-ECMO) at the intensive care unit (ICU) of a tertiary care hospital. Methods: In a retrospective observational study, electronic medical records of 750 patients admitted to the ICU of our hospital between January 1, 2015, and October 31, 2021, were reviewed. Data was collected for patients on VV-ECMO, for whom WOLST was withdrawn during the ICU stay. Clinical characteristics and the underlying reasons for WOLST were compared between those who received PCC (PCC group) and those who did not (non-PCC group). Results: A total of 95 patients were included in our analysis, 63 in the PCC group and 32 in the non-PCC group. The average age of the study population was 48.8 ± 12.6 years, and 64.2% were male. There was no statistically significant difference between the two groups in terms of demographics or clinical characteristics at the time of ICU admission. The average duration of ICU stay and VV-ECMO were 14.1 ± 19.9 days and 9.4 ± 16.6 days, respectively. The number of PCC visits was correlated with the length of ICU stay. The average duration of ICU stay (40.3 ± 33.2 days vs 27.8 ± 19.3 days, P = .05) and ECMO treatment (31.9 ± 27 days vs 18.6 ± 16.1 days, P = .01) were significantly longer in patients receiving PCC than those not receiving PCC. However, the frequency of life sustaining measures or the underlying reasons for WOLST did not significantly differ between the two groups (P > .05). Conclusion: Among ICU patients requiring ECMO support, longer duration of ICU stay and treatment with a higher number of life-sustaining measures seemed to be correlated with the number of PCC visits. The underlying reasons for WOLST seem not to be affected by PCC.

The Impella 5.5® (Abiomed, Danvers, MA, USA) is a microaxial flow pump that promotes left ventricular unloading and improves end-organ perfusion before durable left ventricular assist device (LVAD) implantation. Thrombus formation after Impella 5.5 insertion can occur and represents a significant challenge to device explantation. Durable LVAD implantation is typically performed without aortic cross-clamping, so a dislodged thrombus can potentially embolize and lead to catastrophic events. We describe our technique to safely explant an Impella 5.5 in patients who develop a thrombus on the inflow portion of the device before surgical LVAD implantation.
RESUMO
Managing patients with post-ischaemic ventricular septal defects (VSD) and postcardiotomy cardiogenic shock can be extremely challenging in a low-volume cardiac surgery unit. We present a case of a 68-year-old patient who received veno-arterial extracorporeal membrane oxygenation support due to cardiogenic shock after VSD repair. The patient was successfully weaned off support after 86 h. In the postoperative period, mediastinitis occurred, and negative pressure wound therapy was instituted.

In the early 1960s, heat shock proteins (HSPs) were first identified as vital intracellular proteinaceous components that help in stress physiology and reprogram the cellular responses to enable the organism's survival. By the early 1990s, HSPs were detected in extracellular spaces and found to activate gamma-delta T-lymphocytes. Subsequent investigations identified their association with varied disease conditions, including autoimmune disorders, diabetes, cancer, hepatic, pancreatic, and renal disorders, and cachexia. In cardiology, extracellular HSPs play a definite, but still unclear, role in atherosclerosis, acute coronary syndromes, and heart failure. The possibility of HSP-targeted novel molecular therapeutics has generated much interest and hope in recent years. In this review, we discuss the role of Extracellular Heat Shock Proteins (Ec-HSPs) in various disease states, with a particular focus on cardiovascular diseases.
RESUMO
BACKGROUND: This study assessed in-hospital outcomes of patients with chronic systolic, diastolic, or mixed heart failure (HF) undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). METHODS: The Nationwide Inpatient Sample database was used to identify patients with aortic stenosis and chronic HF who underwent TAVR or SAVR between 2012 and 2015. Propensity score matching and multivariate logistic regression were used to determine outcome risk. RESULTS: A cohort of 9,879 patients with systolic (27.2%), diastolic (52.2%), and mixed (20.6%) chronic HF were included. No statistically significant differences in hospital mortality were noted. Overall, patients with diastolic HF had the shortest hospital stays and lowest costs. Compared with patients with diastolic HF, the risk of acute myocardial infarction (TAVR odds ratio [OR], 1.95; 95% CI, 1.20-3.19; P = .008; SAVR OR, 1.38; 95% CI, 0.98-1.95; P = .067) and cardiogenic shock (TAVR OR, 2.15; 95% CI, 1.43-3.23; P < .001; SAVR OR, 1.89; 95% CI, 1.42-2.53; P ≤ .001) was higher in patients with systolic HF, whereas the risk of permanent pacemaker implantation (TAVR OR, 0.58; 95% CI, 0.45-0.76; P < .001; SAVR OR, 0.58; 95% CI, 0.40-0.84; P = .004) was lower following aortic valve procedures. In TAVR, the risk of acute deep vein thrombosis and kidney injury was higher, although not statistically significant, in patients with systolic HF than in those with diastolic HF. CONCLUSION: These outcomes suggest that chronic HF types do not incur statistically significant hospital mortality risk in patients undergoing TAVR or SAVR.

TandemHeart (Cardiac Assist Inc., Pittsburgh, PA) is a valuable mechanical circulatory support (MCS) device that provides left atrial to femoral artery bypass and directly unloads the left ventricle. The device is inserted under fluoroscopic guidance in the cardiac catheterization laboratory without requiring invasive surgical exposure. However, this device is unique because it directly unloads the oxygenated blood from the left atrium and may be needed for postoperative support in patients undergoing various open cardiac surgeries. In this article, we provide a detailed description of the open surgical insertion of a TandemHeart device.

Frailty and malnutrition in patients with heart failure are barriers to durable left ventricular assist device (D-LVAD) support and heart transplantation. Moreover, cachexia in patients with advanced heart failure carries a high mortality risk. There are no guidelines for these patients other than increased caloric intake and rehabilitation. Patients suffering from cardiac cachexia and heart failure may benefit from temporary, percutaneous assist device support to improve the underlying heart disease and reverse the catabolic state. We retrospectively reviewed patients from January 2017 to January 2022. All patients who received Impella support (5.0 or 5.5, Abiomed) before D-LVAD implantation were screened. Those who met the criteria for cardiac cachexia were included. Patient demographics, nutritional and biochemical markers, and survival data were collected. A total of 14 patients were included. The majority of patients were male (85.7%) with ischemic cardiomyopathy (64.3%). Caloric intake, physical strength, and ambulation improved. Prealbumin levels improved from a median of 13.7-18.0 mg/dl ( p < 0.006) while on Impella 5.0 or 5.5 support. All patients survived to discharge and the 6 month follow-up. In conclusion, use of the Impella device improves cardiogenic shock symptoms and, consequently, may improve cachexia status prior to D-LVAD implantation.

In patients undergoing aortic valve surgery, preoperative reduced left ventricular ejection fraction is not uncommon and is associated with poor outcomes. Mechanical circulatory support (MCS) may be preemptively used in patients presenting with high periprocedural risk. The Impella 5.5 is a percutaneous left ventricular assist device that has been increasingly used in various cardiac surgeries. In this article, we present a step-by-step guide, safeguards, and pitfalls on how to replace the aortic valve and preserve this transaortic MCS device for postoperative support in patients with concomitant aortic valve pathology and left ventricular dysfunction.

BACKGROUND: Delayed sternal closure may be required after left ventricular assist device (LVAD) implantation due to coagulopathy or hemodynamic instability. There is conflicting data regarding infection risk. METHODS: We performed a single-center, retrospective analysis of patients who received their first LVAD between May 2012 and January 2021. Patients were divided into delayed sternal closure (DSC) and primary sternal closure (PSC) groups. We used chi-squared or Fisher Exact tests, as appropriate, to compare the incidence of postoperative LVAD-related infections (mediastinal/sternal wound) and LVAD-specific infections (driveline and pump pocket) after definitive chest closure between these two groups. RESULTS: A total of 327 patients met eligibility criteria, including 127 (39%) patients that underwent DSC and 200 (61%) patients that had a PSC. Demographic and clinical characteristics were similar except for an overrepresentation of men (87% vs. 75%, p = .016), Interagency Registry of Mechanically Assisted Circulatory Support class I-II patients (89% vs 66%, p < .001), patients with a previous sternotomy (43% vs 13%, p < .001), and patients with chronic kidney disease (55% vs 43%, p = .030) in the DSC group. The median DSC time was 24 (IQR: 24-48) hours. The incidence of LVAD-related mediastinal/sternal wound infection was similar between the DSC and PSC groups (4.7% vs 3.0%, p = .419). There was no difference between DSC and PSC groups in the incidence of driveline infection (6.3% vs 9%, p = .411) and pump pocket infection (1.6% vs 1.5%, p =.901), respectively. CONCLUSIONS: DSC does not seem to increase the incidence of LVAD-related or LVAD-specific infection rates in heart failure patients undergoing device implantation surgery.

BACKGROUND: Use of prolonged femoral intra-aortic balloon pump support limits the mobility of patients awaiting heart transplant. We assessed the safety and outcomes of a structured, tilting physical therapy protocol in patients supported by intra-aortic balloon pumps while awaiting transplant. METHODS: We retrospectively reviewed five years of transplant patients. Eighteen patients received femoral intra-aortic balloon support, a heart transplant, and met all eligibility criteria. We compared complications and outcomes between patients who received the structured, tilting physical therapy (Protocol Group) and those that received standard of care (Control Group). RESULTS: Complications were not significantly different between groups. The majority of the Protocol Group were discharged to home (10/12), while half (3/6) of the Control Group were discharged to a rehabilitation facility. Post-transplant length of stay was significantly less in the Protocol Group (median 16 vs. 28 days, p = 0.03). CONCLUSION: Despite the small number analyzed, the data indicates that the structured, tilting physical therapy protocol led to a significantly reduced length of stay post-transplantation. Importantly, use of the protocol did not result in access site complications, thrombosis, or arrhythmias in the majority of the patients.

INTRODUCTION: Advanced age is a known risk factor for poor outcomes after veno-arterial extracorporeal membrane oxygenation (V-A ECMO) for cardiac support. The use of ECMO support in patients over the age of 80 is controversial, and sometimes its use is contraindicated. We aimed to assess the use of ECMO in octogenarian patients to determine survival and complication rates. METHODS: A single-center, retrospective analysis was completed at a large, urban academic medical center. Patients requiring V-A ECMO support between December of 2012 and November of 2019 were included as long as the patient was at least 80 years of age at the time of cannulation. Post cardiotomy shock patients were excluded. RESULTS: A total of 46 patients met eligibility criteria; all received V-A ECMO support. Overall, the majority of patients (71.7%; 33/46) survived to decannulation, and 43.5% (20/46) survived to discharge. Patients who were previously rescued from percutaneous interventions tend to have a better survival than other patients (p = .06). The most common complications were renal and hemorrhagic. CONCLUSIONS: We demonstrated that advanced age alone should not disqualify patients from cannulating and supporting with V-A ECMO.

Atrial perforation and device dislodgment are uncommon encounters after percutaneous left atrial appendage exclusion procedures. The literature describes how various endovascular and surgical approaches can be applied to treat these complications. In this case report, we describe an atrial perforation that occurred after a WATCHMAN™ FLX device (Boston Scientific) deployment. Heart manipulation with lifting was required for the atrial repair. During this maneuver, the device dislodged and was managed by surgical device extraction and left atrial appendage resection and suture closure. Minimal to no manipulation of the left atrium during surgical exploration was found to be invaluable in order to avoid device dislodgement and additional surgical corrective interventions. Additionally, intraoperative transesophageal echocardiography at the beginning and conclusion of the case is key in monitoring the device position and identifying device dislodgement.
