RESUMO

BACKGROUND The worldwide spread of the severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) has created unprecedented situations for healthcare professionals and healthcare systems. Although infection with this virus is considered the main health problem currently, other diseases are still prevalent. CASE REPORT This report describes a 59-year-old man who presented with symptoms of dyspnea and fever that were attributed to Covid-19 infection. His clinical condition deteriorated and further examinations revealed a subjacent severe aortic regurgitation due to acute infective endocarditis. Surgical treatment was successful. CONCLUSIONS The results of diagnostic tests for Covid-19 should be re-evaluated whenever there are clinical mismatches or doubts, as false-positive Covid-19 test results can occur. Clinical interpretation should not be determined exclusively by the Covid-19 pandemic. This case report highlights the importance of using validated and approved serological and molecular testing to detect infection with SARS-CoV-2, and to repeat tests when there is doubt about presenting symptoms.

RESUMO

This article aims to summarize some of the key advances in congenital interventional cardiology over the past few years, from novel imaging technologies, such as virtual reality, fusion imaging, and 3-dimensional printed models, to newly available devices and techniques to facilitate complex procedures including percutaneous pulmonary valve replacement and hybrid procedures. It is an exciting time for the field, with rapid development of techniques, devices, and imaging tools that allow a minimally invasive approach for many congenital cardiac defects with progressively less radiation and contrast doses.

RESUMO

AIMS: The aim of this study was to evaluate the clinical course of COVID-19 in patients who had recently undergone a cardiac procedure and were inpatients in a cardiac rehabilitation department. METHODS: All patients hospitalized from 1 February to 15 March 2020 were included in the study (n = 35; 16 men; mean age 78 years). The overall population was divided into two groups: group 1 included 10 patients who presented with a clinical picture of COVID-19 infection and were isolated, and group 2 included 25 patients who were COVID-19-negative. In group 1, nine patients were on chronic oral anticoagulant therapy and one patient was on acetylsalicylic acid (ASA) and clopidogrel. A chest computed tomography scan revealed interstitial pneumonia in all 10 patients. RESULTS: During hospitalization, COVID-19 patients received azithromycin and hydroxychloroquine in addition to their ongoing therapy. Only the patient on ASA with clopidogrel therapy was transferred to the ICU for mechanical ventilation because of worsening respiratory failure, and subsequently died from cardiorespiratory arrest. All other patients on chronic anticoagulant therapy recovered and were discharged. CONCLUSION: Our study suggests that COVID-19 patients on chronic anticoagulant therapy may have a more favorable and less complicated clinical course. Further prospective studies are warranted to confirm this preliminary observation.

RESUMO

BACKGROUND: Infective endocarditis (IE) is associated with high mortality. Surgery may improve survival and reduce complications, but the balance between benefit and harm is difficult and may be closely related to age and type of surgical intervention. We aimed to examine how age and type of left-sided surgical intervention modified mortality in patients undergoing surgery for IE. METHODS: By crosslinking nationwide Danish registries we identified patients with first-time IE undergoing surgical treatment 2000-2017. Patients were grouped by age < 60 years, 60-75 years, and ≥ 75 years. Multivariable adjusted Cox proportional hazard analysis was used to examine factors associated with 90-day mortality. RESULTS: We included 1767 patients with IE undergoing surgery, 735 patients < 60 years (24.1% female), 766 patients 60-75 years (25.8% female), and 266 patients ≥75 years (36.1% female). The proportions of patients undergoing surgery were 35.3, 26.9, and 9.1% for patients < 60 years, 60-75 years, and > 75 years, respectively. Mortality at 90 days were 7.5, 13.9, and 22.3% (p < 0.001) for three age groups. In adjusted analyses, patients 60-75 years and patients ≥75 years were associated with a higher mortality, HR = 1.84 (95% CI: 1.48-2.29) and HR = 2.47 (95% CI: 1.88-3.24) as compared with patients < 60 years. Factors associated with 90-day mortality were: mitral valve surgery, a combination of mitral and aortic valve surgery as compared with isolated aortic valve surgery, age, diabetes, and prosthetic heart valve implantation prior to IE admission. CONCLUSIONS: In patients undergoing surgery for IE, mortality increased significantly with age and 1 in 5 died above age 75 years. Mitral valve surgery as well as multiple valve interventions augmented mortality further.

RESUMO

OBJECTIVE: The aim of this study was to describe the clinical course of a consecutive series of patients operated of urgent cardiac surgery during COVID-19 outbreak. BACKGROUND: In Italy, COVID outbreak has mostly occurred in the metropolitan area of Milan, and in the surrounding region of Lombardy, and previously "conventional" hospitals were converted into COVID spokes to increase ICU beds availability, and to allow only urgent CS procedures. METHODS: Among urgent CS patients (left main stenosis with unstable angina, acute endocarditis, valvular regurgitation with impending heart failure), 10 patients (mean age = 57 ± 9 years), despite a negative admission triage, developed COVID-pneumonia postoperatively, at a median of 7 days after CS. RESULTS: Patients showed typical lymphopenia, higher prothrombotic profile, and higher markers of inflammation (ferritin and interleukin-6 values). At the zenith of pulmonary distress, patients presented with severe hypoxia (median PaO2/FIO2 ratio = 116), requiring advanced noninvasive ventilation (Venturi mask and continuous positive airway pressure) in the majority of cases. All patients were treated with hydroxychloroquine, azithromycin, and low-molecular-weight heparin at anticoagulant dose. Overall in-hospital mortality was 10% (1/10), peaking 25% in patients who developed COVID pneumonia immediately after CS. The remaining patients, with late infection, were all discharged home without oxygen support, at a median of 25 days after symptom onset. CONCLUSIONS: As postoperative mortality in case of COVID pneumonia is not negligible, meticulous rules (precise triage, safe hospital path, high level of protection for health-care teams, prompt diagnosis of suspicious symptoms) should be strictly followed in patients undergoing CS during COVID pandemic. The role of therapies alternative to CS should be further assessed.

RESUMO

The coronavirus disease (COVID) pandemic and the decision-making process of whether to perform urgent procedures during a surge are issues that will likely not disappear in the near future as reflected by the current rise in COVID cases in the southern and western United States and the resurgent numbers of confirmed cases around that world leading to are leading to new lock-downs. Multi-disciplinary discussions will continue to be important to decide individual risk and benefit profiles for patients with asymptomatic COVID patients moving forward. While imperfect, this most recent study provides more insight to some of the risks that should be weighed in these discussions. Further prospective, longitudinal research and better understanding of the heterogeneity of the COVID positive patient will further enhance understanding the decision-making process in the cardiac surgical patient through these difficult times.

RESUMO

Teleproctoring can be used successfully in performing challenging and innovative structural heart interventions using sophisticated technology that allows real-time bidirectional audiovisual communication with digital transmission of live videos and direct observation of the operative field by a remote proctor. The authors share an illustrative case that was performed amid the coronavirus disease-2019 global pandemic that led to travel restrictions to limit spread of the virus. Teleproctoring has future implications beyond the current global health crisis to facilitate rapid dissemination and exchange of knowledge for ultimately helping patients around the globe.

RESUMO

Objective: To explore the efficacy and safety of open cardiac operation and interventional therapy in pregnant patients and describe the feto-neonatal and maternal outcomes. Methods: A retrospective study of 39 cases of women undergoing open cardiac operation or interventional therapy during pregnancy was conducted in Guangdong Provincial People's Hospital from Jan. 2014 to Oct. 2019. Results: The age of 39 pregnant women with gestational heart disease was (30±6) years old (21-43 years old). Among them, 37 cases were single and 2 cases were twin pregnancy. Modified World Health Organization (mWHO) pregnancy risk classification were all level Ⅳ. There were 22 women receiving cardiac operation under cardiopulmonary bypass during pregnancy, 14 patients undergoing percutaneous balloon mitral valvuloplasty, 2 patients accepting percutaneous balloon pulmonary valvuloplasty, and 1 case receiving atrial septal defect occluder with ultrasound guidance. Three were no maternal deaths during and after the operation. One patient had an inevitable abortion. Four fetuses died in the uterine after open cardiac surgery. There patients chose termination of the pregnancy after cardiac operation. There were 31 live birth, in which 7 cases were preterm live birth and 24 patients were term live birth. The total number of newborns were 33. Two fetuses suffered neonatal intracranial hemorrhage and died after birth. Thirty-one fetuses were alive and born without any abnormity. Conclusion: For pregnant women with high risk of cardiovascular disease and classified as mWHO pregnancy risk level Ⅳ, cardiopulmonary bypass and interventional therapy during pregnancy could be used as an alternative for better materal and fetal outcomes.

RESUMO

The issue of postoperative arrhythmias requiring pacemaker therapy is widely studied in the field of cardiac surgery and it is a complex perioperative problem. The aim of this paper is to summarize the relevant international guidelines and recommendations and to present our hospital's experience. We present the current, decisive recommendations and important studies, and present patients who underwent pacemaker implantation within one month after cardiac surgery between 01. 01. 2014 and 31. 12. 2018 in our hospital and compare them with the international findings. According to the international literature, the rate of permanent pacemaker implantation after cardiac surgery ranges from about 1.5% to 5%, and this rate seems to increase later. We have detailed information and many identified predictors about the development of conduction disturbances, but the current guidelines provide only weak recommendations. In the early perioperative period (1 month), pacemaker implantation was required in 15 cases (0.55%); in the course of long-term follow-up, 6 patients were still pacemaker-dependent. Perioperative arrhythmias are frequent and serious complications after cardiac surgery, prolong patient recovery time and put financial burden on the hospitals. The rate of need for a permanent pacemaker is low in our hospital, and in the late follow-up we can find only a small part of patients with pacemaker dependency. It would be necessary to start a prospective study and to develop a standardized protocol based on the information currently available. This would be a useful and authoritative help for the postoperative care in cardiac surgery. Orv Hetil. 2020; 161(31): 1271-1280.

RESUMO

OBJECTIVE: By the end of February 2020, the COVID-19 pandemic infection had spread in Northern Italy, with thousands of patients infected. In Lombardy, the most affected area, the majority of public and private hospitals were dedicated to caring for COVID-19 patients and were organized following the 'Hub-and-Spoke' model for other medical specialties, like cardiac surgery and interventional procedures for congenital cardiac disease (CHD). Here, we report how the congenital cardiac care system was modified in Lombardy and the first results of this organization. METHODS: We describe a modified 'Hub-and-Spoke' model - that involves 59 birthplaces and three specialized Congenital Cardiac Centers -- and how the hub center organized his activity. We also reported the data of the consecutive cases hospitalized during this period. RESULTS: From 9 March to 15 April, we performed: a total of 21 cardiac surgeries, 4 diagnostic catheterizations, 3 CT scans, and 2 CMR. In three cases with prenatal diagnosis, the birth was scheduled. The spoke centers referred to our center six congenital cardiac cases. The postop ExtraCorporeal Membrane Oxygenation support was required in two cases; one case died. None of these patients nor their parents or accompanying person was found to be COVID-19-positive; 2 pediatric intensivists were found to be COVID-19-positive, and needed hospitalization without mechanical ventilation; 13 nurses had positive COVID swabs (4 with symptoms), and were managed and isolated at home. CONCLUSION: Our preliminary data suggest that the model adopted met the immediate needs with a good outcome without increased mortality, nor COVID-19 exposure for the patients who underwent procedures.

RESUMO

BACKGROUND: Covid-19 was declared a pandemic by the World Health Organization (WHO) on 11 March 2020. Responses to this crisis integrated resource allocation for the increased amount of infected patients while maintaining an adequate response to other severe and life-threatening diseases. Though cardiothoracic patients are at high risk for Covid-19 severe illness, postponing surgeries would translate to increased mortality and morbidity. We reviewed our practice during the initial time of the pandemic, with emphasis on safety protocols. METHODS: From 11 March to 15 May 2020, 148 patients underwent surgery at the Department of Cardiothoracic Surgery of Centro Hospitalar Universitário de São João. The clinical characteristics of the patients were retrospectively registered, along with novel containment and infection prevention measures targeting the new coronavirus. RESULTS: The majority of adult cardiac patients were operated on an emergency basis. Hospital mortality was 1.9% (n = 2 patients). Most adult thoracic patients were admitted from home, with a diagnosis of neoplastic disease in 60% of patients. Hospital mortality was 3.3% (1 patient). Fifteen children underwent cardiothoracic surgery. There was no mortality. The infection prevention procedures applied, totally excluded the transmission of Covid-19 in the department. CONCLUSION: While guaranteeing a prompt response to emergent, urgent, and high priority cases, novel safety measures in individual protection, patients circuits, and preoperative diagnoses of symptomatic and asymptomatic infection were adopted. The surgical results corroborate that it was safe to undergo cardiothoracic surgery during the initial time of the Covid-19 pandemic. The new policies will be maintained while the virus stays in the community.

RESUMO

BACKGROUND: Double-outlet left ventricle (DOLV) is a rare congenital cardiac anomaly. The aorta and the main pulmonary arterial trunk arises predominantly from the left ventricle and is associated with a malaligned ventricular septal defect, various degrees of hypoplasia of the right ventricle, and presence, or absence of pulmonary stenosis. Bi-ventricular repair is the preferred treatment option whenever possible. Multiple techniques for bi-ventricular repair have been described. The best option for DOLV correction is by translocating the pulmonary root from the left ventricle to the right ventricle. In this series, we report four patients who underwent biventricular repair of DOLV with excellent outcomes. METHODS: This is a retrospective study of four patients who underwent surgical correction of DOLV between January 2014 and December 2018. We collected all patient details from the institute patient record system. Echocardiographic data were obtained from the records. Intraoperative charts were reviewed for further information on the surgical procedure and cardiopulmonary bypass. Postoperative data included survival, functional status, and followup echocardiography. RESULTS: Of the four children, three underwent pulmonary root translocation, and one child underwent a Reparation al etage Ventriculaire (REV) procedure. There was no mortality in our series, and all children are in a stable clinical condition in the recent follow-up, and no re-operations or interventions were required following primary surgical correction. CONCLUSION: DOLV is anatomically and surgically a challenging subset. Pulmonary root translocation in this anatomy is technically challenging but safe and superior option when compared to other alternative surgical procedures. Pulmonary root translocation can be performed with excellent results, even in infants.

RESUMO

The novel coronavirus, now termed SARS-CoV-2, has caused a significant global impact in the space of 4 months. Almost all elective cardiac surgical operations have been postponed in order to reduce transmission and to allocate resources adequately. Urgent and emergency cardiac surgery is still taking place during the pandemic. The decision to operate in urgent patients with active/recent COVID-19 infection is difficult to make, particularly as it is still an unknown disease entity in the setting of emergent cardiac surgery. We present a case series of three patients who underwent urgent cardiac surgery and who have had recent or active COVID-19 infection.

RESUMO

The recommendations in which the Mexican Society of Cardiology (SMC) in conjunction with the National Association of Cardiologists of Mexico (ANCAM) as well as different Mexican medical associations linked to cardiology are presented, after a comprehensive and consensual review and analysis of the topics related to cardiovascular diseases in the COVID-19 pandemic. Scientific positions are analyzed and responsible recommendations on general measures are given to patients, with personal care, healthy eating, regular physical activity, actions in case of cardio-respiratory arrest, protection of the patient and health personnel as well as precise indications in the use of non-invasive cardiovascular imaging, prescription of medications, care in specific topics such as systemic arterial hypertension, heart failure, arrhythmias and acute coronary syndromes, in addition to emphasizing electrophysiology, interventionism, cardiac surgery and in cardiac rehabilitation. The main interest is to provide the medical community with a general orientation on what to do in daily practice and patients with cardiovascular diseases in the setting of this unprecedented epidemiological crisis of COVID-19.

RESUMO

OBJECTIVE: To evaluate bacterial flora in patients with deep sternal wound infection and the effect of negative pressure wound therapy on eradication of the pathogen. MATERIAL AND METHODS: There were 102 patients with deep wound infection after cardiac surgery. Mean age was 66.9±9.9 years. Diabetes mellitus was detected in 21 (20.5%) cases, chronic obstructive pulmonary disease - in 15 (14.7%). Wound debridement via daily dressings was performed in 64 patients; vacuum-assisted dressings were applied in 38 patients. Bacteriological analysis of discharge was carried out every week.Results. Mixed infection was observed in 38 (37.3%) patients. S.aureus was the most common pathogen (n=51, 50%), Gram negative bacteria were found in 36 (35.3%) patients. Negative pressure wound therapy ensured eradication of S.aureus within 3 weeks while dressings were associated with only 40% decrease of the incidence of positive analyses (p<0.05). Effectiveness of the method was not obtained for Gram negative bacteria. CONCLUSION: Negative pressure wound therapy accelerates eradication of Gram positive pathogens but does not affect eradication of Gram negative microbes.

RESUMO

BACKGROUND: No firm recommendations are currently available to guide decision making for patients requiring cardiac surgery during the coronavirus disease 2019 (COVID-19) pandemic. Systematic appraisal of senior surgeons' consensus can be used to generate interim recommendations until data from clinical observations become available. Hence, we aimed to collect and quantitatively appraise nationwide UK consultants' opinions on clinical decision making for patients requiring cardiac surgery during the COVID-19 pandemic. METHODS: We E-mailed a Web-based questionnaire to all consultant cardiac surgeons through the Society for Cardiothoracic Surgery in Great Britain and Ireland mailing list on the April 17, 2020, and we predetermined to close the survey on the April 21, 2020. This survey was primarily designed to gather information on UK surgeons' opinions using 12 items. Strong consensus was predefined as an opinion shared by at least 60% of responding consultants. RESULTS: A total of 86 consultant surgeons undertook the survey. All UK cardiac units were represented by at least 1 consultant. Strong consensus was achieved for the following key questions: (1) before any hospital admission for cardiac surgery, nasopharyngeal swab, polymerase chain reaction, and computed tomography of the chest should be performed; (2) the use of full personal protective equipment should to be adopted in every case by the theater team regardless of the patient's COVID-19 status; (3) the risk of COVID-19 exposure for patients undergoing heart surgery should be considered moderate to high and likely to increase mortality if it occurs; and (4) cardiac procedures should be decided based on a rapidly convened multidisciplinary team discussion for every patient. The majority believed that both aortic and mitral surgery should be considered in selected cases. The role of coronary artery bypass graft surgery during the pandemic was controversial. CONCLUSIONS: In this unprecedented pandemic period, this survey provides information for generating interim recommendations until data from clinical observations become available.

RESUMO

The current protocol describes methods to generate scalable, mesh-shaped engineered cardiac tissues (ECTs) composed of cardiovascular cells derived from human induced pluripotent stem cells (hiPSCs), which are developed towards the goal of clinical use. HiPSC-derived cardiomyocytes, endothelial cells, and vascular mural cells are mixed with gel matrix and then poured into a polydimethylsiloxane (PDMS) tissue mold with rectangular internal staggered posts. By culture day 14 ECTs mature into a 1.5 cm x 1.5 cm mesh structure with 0.5 mm diameter myofiber bundles. Cardiomyocytes align to the long-axis of each bundle and spontaneously beat synchronously. This approach can be scaled up to a larger (3.0 cm x 3.0 cm) mesh ECT while preserving construct maturation and function. Thus, mesh-shaped ECTs generated from hiPSC-derived cardiac cells may be feasible for cardiac regeneration paradigms.
