Coronary artery bypass grafting after iatrogenic coronary artery dissection: A single center eight years' experience

Background: Iatrogenic coronary artery dissection during diagnostic or therapeutic catheterization is a rare and mortal complication that may result in a newly developed myocardial infarction. In this study, we aimed to share the results of CABG treatment of patients with iatrogenic coronary artery dissection after coronary angiography (CAG) in our clinic. Method(s): All patients who underwent CAG or percutaneous coronary intervention (PCI) in our hospital between January 2014 and December 2021 were analyzed retrospectively and patients who underwent CABG after iatrogenic coronary artery dissection were included in the study. The dissection classification was achived according to the National Heart, Lung and Blood Institute (NHLBI) classification. Result(s): During the eight years, CAG was applied to 20,398 patients and PCI to 9583 patients. Needed to treat CABG in iatrogenic coronary artery dissection developed in 17 of the patients (0.06%). LMCA was dissected in 6 (35.3%) patients and LAD in 6 (35.3%), CX in 2 (11.8%) and RCA dissection in 3 (17.6%). 3 patients (17.6%) had an intubation time longer than 48 hours. One of them has recently had a COVID infection. Another was suffering from pulmonary edema. The other patient died on the 4th postoperative day due to low cardiac output. The length of stay in the intensive care unit was 2 (min: 1 - max: 13) days. The hospital stay was 6 (min: 4 - max: 20) days. Conclusion(s): The development of a critical clinical condition prior to surgery is strongly associated with a higher probability of early and late postoperative death. For this reason, it is clear that the treatments applied at every stage of the pre-, per-, and postoperative period are the most important determinants of the results.Copyright © 2023, CKS.

The Coronavirus Double Threat: A Rare Presentation of Chest Pain in a Young Female.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV 2) led to global coronavirus disease 2019 (COVID-19) pandemic. The virus affects the respiratory system predominantly and has resulted in multiorgan complications. Myocarditis, acute coronary syndrome (ACS), cardiogenic shock, and sudden cardiac death were common cardiac manifestations of COVID-19. Spontaneous coronary artery dissection (SCAD) is a rare form of coronary artery disease that is previously reported in patients with COVID-19. SCAD usually occurs in a middle-aged woman with few or without any cardiovascular risk factors. The gold standard for its diagnosis is coronary angiography. The SCAD treatment recommendations depend on the hemodynamic status: conservative therapy in hemodynamically stable SCAD patients and urgent revascularization in hemodynamically unstable SCAD patients. The exact pathophysiology of COVID-19 associated with SCAD is unknown. It is considered a combination of systemic inflammatory response and localized vascular inflammation. The case reported is of COVID-19-associated SCAD in a patient with no history of cardiovascular disease later complicated by the transient ischemic attack (TIA) and left ventricular (LV) thrombus.

Superior Cerebellar Artery Dissection in a Patient Diagnosed with Reversible Cerebral Vasoconstriction Syndrome: A Case Report

Arterial dissection is an uncommon complication of reversible cerebral vasocon-striction syndrome (RCVS). We describe the case of a 35-year-old woman with a migraine history who presented with recurrent thunderclap headache and focal neurological signs, including right hemiataxia. She had been diagnosed with COVID-19 disease two weeks earlier. Neuroimaging revealed multifocal stenosis of the posterior circulation arteries and dissection of the right superior cerebellar artery. She improved significantly throughout her one-week hospitalization and maintained only mild ataxia. The interplay between COVID-19 disease, RCVS, and arterial dissection requires further investigation.Copyright © Author(s) (or their employer(s)) and Sinapse 2022.

COVID-19 and Spontaneous Coronary Artery Dissection: Association or Causality

Clinical Information Patient Initials or Identifier Number: JS Relevant Clinical History and Physical Exam: A 55-year old woman was brought to emergency department complaining of sudden onset squeezing chest pain radiating to her arm and jaw and associated with giddiness. She had flu like illness a day prior to her presentation associated with malaise, arthralgia and dry cough. She had history of hypertension. Physical examination revealed dual heart sounds and clear lung fields to auscultation. Relevant Test Results Prior to Catheterization: Electrocardiogram (ECG) showed normal sinus rhythm and the cardiac enzymes were elevated;high sensitivity troponin-I, 23000 ng/L (range0-10 ng/L). RNA PCR was positive for SARS-CoV-2 (COVID-19). D-Dimer was 303microgram/L (normal <500). Transthoracic echocardiogram showed severe hypokinesis of the mid inferolateral wall with left ventricular ejection fraction (LVEF) 52%. Chest X-ray showed no focal consolidation. [Formula presented] [Formula presented] Relevant Catheterization Findings: Invasive coronary angiogram showed tortuous coronary arteries with abrupt narrowing of mid- distal Ramus Intermiedius and discrete lesion of mid PDA. SCAD (spontaneous Coronary dissection) of Ramus Intermedius and mid PDA (posterior descending artery) was suspected, and patient was treated conservatively. Repeat coronary angiography, few months later showed complete resolution of SCAD with normal appearance of affected vessels. [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: After obtaining an informed consent right Radial access was achieved with 6F Terumo sheath using over the wire technique. 1% lignocaine was used as local anaesthetic. 5F JL 3.5 (Judkin's) and JR 4 catheters were used to engage left main stem (LMS) and right coronary artery (RCA) and selective coronary angiography was performed. No percutaneous coronary intervention was performed. After the procedure hemoband (TR band) was applied to access site. Patient remained hemodyanamically stable throughout the procedure. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): SCAD is a potential cause of type II myocardial infarction in patients with COVID-19, but more studies are needed to establish causality. Infection-related SCAD may occur at any time during index events and could be difficult to diagnose. Conservative management seems like a safe strategy.Copyright © 2023

A Rare Case of Heart Failure in Third Trimester Pregnancy - Diagnostic and Therapeutic Dilemma

Background Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare disorder. Case A 20-year-old, 36-week pregnant female (G1P0) presented with acute shortness of breath, sharp chest pain and fever. She was COVID-19 positive and required BiPAP. Echocardiogram showed 40% EF, dilated LV with global hypokinesis and moderate mitral regurgitation (MR). She was hypotensive and on oxygen despite diuresis, emergent cesarean and COVID-19 treatment. Left heart catheterization showed anomalous takeoff of the left main coronary artery (LCA) from the dilated pulmonary artery (PA) with coronary steal (Figure 1). She had ALCAPA repair with LIMA to LAD bypass grafting. Decision-making Differential diagnoses included peripartum cardiomyopathy, Covid-myocarditis, pulmonary embolism, and spontaneous coronary artery dissection. LHC was performed only when symptoms failed to improve and troponin kept rising. ALCAPA has two major clinical subtypes - Infantile type and adult type. Adult type presents as dyspnea, chest pain, reduced exercise ability, and sudden cardiac death. Despite having good RCA to LCA collaterals, adult patients can still have ongoing ischemia of the LV myocardium, causing ischemic MR, malignant ventricular dysrhythmias. Diagnosis was delayed due to pregnancy and COVID-19 infection. Conclusion ALCAPA is a lethal coronary disorder. Elevated troponin and dilated cardiomyopathy with acute MR should raise suspicion of ALCAPA in young adults. [Formula presented]Copyright © 2023 American College of Cardiology Foundation

Discussion on the causes of thrombolysis failure in a patient with STEMI: a case report.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) has emerged as an increasingly diagnosed cause of ST-segment elevation myocardial infarction (STEMI), which is easily missed or delayed. The effective use of coronary angiography (CAG) and advanced intracoronary imaging examinations in STEMI patients has led to increased detection of SCAD. CASE PRESENTATION: A 59-year-old woman with acute angina pectoris was diagnosed with STEMI detected by electrocardiography combined with measurement of myocardial enzymes. Due to the ongoing pandemic of coronavirus disease 2019 (COVID-19) in Wuhan, she was first given thrombolytic therapy after excluding contraindications according to the requirements of the current consensus statement; however, subsequently, both the symptoms of ongoing chest pain and the electrocardiographic results indicated the failure of thrombolytic therapy, so the intervention team administered rescue percutaneous coronary intervention treatment under third-grade protection. CAG confirmed total occlusion in the distal left anterior descending (LAD) artery, with thrombolysis in myocardial infarction (TIMI) 0 flow, whereas the left circumflex and right coronary arteries appeared normal, with TIMI 3 flow. Intravenous ultrasound (IVUS) was further performed to investigate the causes of occlusion, which verified the absence of atherosclerosis but detected SCAD with intramural haematoma. During the operation, the guidewire reached the distal end of the LAD artery smoothly, the balloon was dilated slightly, and the reflow of TIMI blood could be seen by repeated CAG. During the follow-up period of one and a half years, the patient complained of occasional, slight chest tightness. The repeated CAG showed that the spontaneous dissection in the LAD artery had healed well, with TIMI 3 flow. The repeated IVUS confirmed that the SCAD and intramural haematoma had been mostly resorbed and repaired. CONCLUSION: This was a case of failed STEMI thrombolysis in our hospital during the outbreak of COVID-19. This case indicates that doctors need to consider the cause of the disease when treating STEMI patients, especially patients without traditional cardiovascular risk factors. Moreover, CAG and intracoronary imaging examinations should be actively performed to identify the aetiology and improve the treatment success rate.

Neurological Manifestations In COVID-19 Patients: An Imaging Review

Background: The COVID-19 pandemic that started in late 2019, has posed a great health challenge to India rapidly elevating our country to the second most affected nation after the United States. While the respiratory manifestations of COVID-19 are widely-known, there is paucity of information on its neurological manifestations in Indian literature. The imaging features of the diverse neurological presentations such as stroke, encephalitis, demyelination, hemorrhages and vascular involvement are reviewed in this article. Objective of the review is to discuss the spectrum of neuroimaging features in COVID-19. Method(s): Multiple publications from systematic and cohort studies on neuroimaging are reviewed in this article. Due permission was obtained from the publishers to reproduce the illustrations because of lack of adequate neuroimaging data in our country. Result(s): Ischemic infarcts, micro-hemorrhages, parenchymal hematomas and white matter changes, both diffuse and focal were the most common manifestations. Acute necrotizing hemorrhagic encephalitis, features resembling posterior reversible encephalopathy syndrome (PRES) and acute demyelinating encephalomyelitis (ADEM), arterial dissections, dural sinus and deep venous thrombosis were reported. Olfactory bulb and white matter signal ratios were elevated in anosmic patients. Micro-structural changes such as remyelination and neurogenesis indicated processes of repair. Conclusion(s): Ischemic and hemorrhagic lesions are the most common neuroimaging abnormalities in COVID-19 patients, though 40% of the studies are normal. Awareness of the imaging features is essential for management of these patients in the current pandemic. Severity of illness and risk of spread of infection are major constraints for neuroimaging.

Decline in spontaneous cervical artery dissection incidence during COVID-19 public health measures: Evidence for a role of upper respiratory infections in pathogenesis.

BACKGROUND: Upper respiratory infections have been suggested as a risk factor for spontaneous cervical artery dissection (sCeAD). If this is the case, public health measures implemented to contain the spread of SARS-CoV-2, which also reduced other communicable diseases such as influenza, might be associated with a reduction in cervical artery dissection incidence. AIMS: We determined the incidence of sCeAD before, during and after the COVID-19 pandemic, and the associated public health measures. METHODS: All patients suffering an sCeAD and seen in Innsbruck Austria, between January 2002 to December 2016 (pre-COVID comparators) and between January 2020 to August 2022 were recorded through two individual prospective cohort studies. We compared admission rates, demographic, and clinical characteristics of sCeAD patients in pre-COVID-19 and COVID-19 times. RESULTS: In total, 249 sCeAD patients were admitted prior to the COVID-19 pandemic compared to 20 during its course. Baseline characteristics of sCeAD subjects did not differ in subjects admitted during and prior to the pandemic. Following the introduction of public health measures for the pandemic, there was a marked decrease of sCeAD admissions from 16.5 per year to 6.3 per year (p = 0.012). Since the measures were ended the number of sCeAD admissions increased again. In contrast, the number of all ischemic stroke patients treated at the Medical University of Innsbruck did not alter during the pandemic. (N per year: 633 in 2015, 687 in 2017, 684 in 2019, 731 in 2020, and 717 in 2021). CONCLUSION: The incidence of sCeAD fell markedly during the pandemic and this may have resulted from the public health measures introduced and a subsequent reduction in upper respiratory infections. Our study provides indirect evidence for a role of infection in the pathogenesis of sCeAD.

Bilateral Carotid Artery Dissections and Ischemic Stroke in a Patient With COVID-19: A Case Report.

An unresponsive patient with COVID-19 infection should prompt immediate evaluation with consideration of a vast differential diagnosis entailing a multitude of diagnostic and therapeutic interventions in the emergency department. We report a case of an unresponsive 41-year-old female with COVID-19 infection and a history of rheumatoid arthritis who presented to the emergency department with bilateral carotid artery dissections and left internal carotid artery thrombus that extended into the middle cerebral artery. This case calls into question if COVID-19 is coincidentally or causally associated with acute vascular and thromboembolic disease.

Spontaneous Coronary Artery Dissection Following SARS-CoV-2-Associated Multisystem Inflammatory Syndrome.

Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of acute coronary syndrome, myocardial infarction, and sudden cardiac death. During the coronavirus disease 2019 (COVID-19) pandemic, a multisystem inflammatory syndrome (MIS) emerged that is incompletely understood. While the involvement of numerous organ systems has been described, the potential cardiovascular manifestations, such as myocarditis, arterial thrombosis, or SCAD, are particularly worrisome. Here, we present a case of MIS that was preceded by an unremarkable case of COVID-19 and followed by the development of SCAD. This case highlights the importance of furthering our understanding of the potential sequelae of COVID-19 and of the potential relationship between SCAD and MIS.

The prevalence and course of COVID-19 and the Cardiovascular Diseases

The SARS-CoV2 virus has infected over 545 million people and has claimed over 6 million lives globally by the end of June 2022. The global case fatality rate ranged from 5.5% in Mexico, 2.1-2.5% in South Africa, Brazil, Guatemala, Russia, 1.1-1.5% in the United States, Canada, India and Chile, 0.5-0.9% in Western European countries, 0.3% in Japan, 0.2% in Taiwan to 0.1% in Australia. Among hospitalized COVID-19 patients, the prevalence of pre-existing cardiovascular diseases was approximately 10%. The prevalence of cardiovascular diseases among COVID-19 non-survivors and COVID-19 patients requiring intensive care unit admission were approximately 20-30%. In a multicenter study of 8910 COVID-19 patients from 169 hospitals in Asia, Europe and North America, presence of pre-existing coronary artery disease, chronic heart failure and cardiac arrhythmia was associated with increased mortality of 10.2%, 15.3% and 11.5% respectively, compared with 5-6% mortality in those without the above co-morbidities. The systemic inflammation caused by SARS-CoV-2 could lead to a wide spectrum of cardiovascular complications including acute cardiac injury, acute coronary syndrome, coronary artery dissection, acute myocarditis, cardiomyopathy, chronic heart failure, cardiac arrhythmia, pulmonary embolism, cardiogenic shock, circulatory failure or even cardiac arrest.

CASE REPORT OF SPONTANEOUS CORONARY ARTERY DISSECTION IN A PATIENT POSITIVE FOR COVID-19

SESSION TITLE: Cardiovascular Complications in Patients with COVID-19 SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 1:45 pm INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is a rare cardiac phenomenon associated with autoimmune and inflammatory conditions seen often in young women with few conventional atherosclerotic risk factors. The presentation is indistinguishable from acute coronary syndrome and can lead to acute myocardial infarction, arrhythmias, and sudden death. We share a thought-provoking case of SCAD in a COVID-19 positive patient. CASE PRESENTATION: 51-year-old physically fit female with BMI of 22.46kg/m2, non-diabetic with recent unremarkable lipid panel and history of anxiety, postpartum cardiomyopathy 15 years prior with recovered ejection fraction presented with complaints of midsternal chest pain at rest, 9/10 intensity, radiating to the right shoulder associated with dyspnea, lasting for 3 hours until relieved by nitroglycerine patch. Initial workup revealed troponin of 3.08 and EKG consistent with acute ischemic changes without STEMI. She was incidentally found positive for SARS-CoV-2. Echocardiogram showed dyskinetic apex with normal ejection fraction. The following day, while she was on aspirin and heparin drip, she developed chest discomfort with EKG revealing dynamic T wave inversions and troponin trending up to 14.79. The patient was taken for an emergent cardiac catheterization which revealed patent coronaries with concern for distal left anterior descending artery dissection. Subsequently, the patient was continued on a heparin drip with an improvement of her symptoms. Troponin declined to 7.97 with no other COVID-19 related concerns. She was deemed medically stable and discharged home after completing her isolation. Furthermore, she underwent a cardiac and coronary artery CT angiogram 2 weeks later, showing patent coronaries and a calcium score of 0 and no findings of coronary artery disease. DISCUSSION: SCAD is an emergent condition closely associated with inflammatory conditions, systemic arteriopathy, emotional stress triggers, fibromuscular dysplasia, and pregnancy. It is not iatrogenic, traumatic or associated with atherosclerosis. The mainstay of detection of SCAD is coronary angiography. In our patient, since it was a distal LAD disease, the echo findings of dyskinetic apex helped established the diagnosis of SCAD. Management is mainly supportive usually carrying a good prognosis. In our case report, the connecting factor to SCAD was the presence of SARS-CoV-2. Our patient was without traditional risk factors for coronary artery disease, which reinforced the likelihood of SCAD instead of acute coronary syndrome. CONCLUSIONS: Thus, as the manifestations, complications, and sequelae of COVID-19 continue to emerge, we believe SCAD needs to remain a top differential in COVID -19 positive patients presenting with symptoms of the acute coronary syndrome. To better elucidate the pathophysiology of SCAD in SARS-CoV-2 patients, we encourage further vigilance of this phenomenon. Reference #1: Hayes, S. N. et al (2018, February 22).

Spontaneous coronary artery dissection in a patient with recent COVID-19 infection: A case report.

We report a spontaneous coronary artery dissection (SCAD) case in a lady with a history of recent COVID-19 and without any known predisposing factors. We also highlight the value of CMR as a noninvasive tool for tissue characterization, which can also be more applicable during the COVID-19 pandemic.

DISSECTING COVID-19 - A RARE CASE OF SPONTANEOUS CORONARY ARTERY DISSECTION IN THE SETTING OF RECENT COVID-19 INFECTION

CASE: A 67 year old woman with no known cardiac history presented after acute onset chest pain while watching TV. The pain was described as a burning, substernal pain associated with shortness of breath and nausea. She had no prior history of similar chest pain and was recently exercising with no complaints. Her pain was not relieved by Tums, so she presented to the ED. A COVID-PCR test was positive on admission, however the patient stated she had the infection three weeks prior to presentation and was asymptomatic. She was given sublingual nitroglycerin which improved her pain. Vital signs and physical exam were unremarkable. Electrocardiogram demonstrated ST elevations in leads V3 and V4 with an initial troponin of 0.1 ng/ml (reference range <0.80 ng/ml). She subsequently was loaded with aspirin, a heparin bolus, and was taken to the cath lab. There, she was found to have a distal LAD spontaneous coronary artery dissection and underwent POBA with restoration of vessel flow. IMPACT/DISCUSSION: Spontaneous coronary artery dissection (SCAD) is a condition predominantly seen in women without conventional risks for coronary disease and an often missed cause of non-atherosclerotic ACS. Most often, patients present with typical chest pain and dynamic ECG changes. Diagnosis of SCAD is made during coronary angiogram, at times with the aid of intravascular ultrasound or OCT. Often, these patients will have associated conditions such as fibromuscular dysplasia, pregnancy/postpartum status, or connective tissue diseases. We describe a unique case of a patient without any cardiac risk factors presenting with SCAD after the resolution of an asymptomatic COVID-19 infection. Cardiac complications of COVID-19 have been extensively described, from myocarditis, myocardial infarction, heart failure, and arrhythmias. However, published literature on the association between COVID-19 and SCAD is sparse, with a few case reports reporting a possible connection. Among these, the majority of patients were acutely symptomatic with COVID-19 and subsequently developed angina during the hospitalization. There was one similar case describing a patient developing SCAD after the resolution of a COVID infection 3 months prior to presentation. However, this patient had factors which could have contributed to the SCAD. SCAD is associated with inflammatory diseases that lead to vessel wall weakness. COVID-19 induces a marked inflammatory and immune response during infection, which has been found to cause endothelial and smooth muscle damage. It is possible the inflammatory response from the infection could promote fragility of coronary vessels and lead to dissection. CONCLUSION: As the relationship between SCAD and COVID-19 continues to be explored, providers must be mindful of the potential cardiac manifestations of the virus. An index of suspicion for SCAD should be maintained in patients with COVID-19 or a history of COVID-19 presenting with acute myocardial infarction with few or no atherosclerotic risk factors.

Cardiovascular Complications of Pregnancy-Associated COVID-19 Infections.

Cardiovascular complications are frequently present in coronavirus-2019 (COVID-19) infection. These include microvascular and macrovascular thrombotic complications such as arterial and venous thromboembolism, myocardial injury or inflammation resulting in infarction, heart failure, and arrhythmias. Data suggest increased risk of adverse outcomes in pregnant compared with nonpregnant women of reproductive age with COVID-19 infection, including need for intensive care unit admission, mechanical ventilation, and extracorporeal membrane oxygenation utilization. Current statements addressing COVID-19-associated cardiac complications do not include pregnancy complications that may mimic COVID-19 complications such as peripartum cardiomyopathy, spontaneous coronary artery dissection, and preeclampsia. Unique to pregnancy, COVID-19 complications can result in preterm delivery and modify management of the pregnancy. Moreover, pregnancy has often been an exclusion criterion for enrollment in research studies. In this review, we summarize what is known about pregnancy-associated COVID-19 cardiovascular complications.

Pediatric Cerebral Infarction associated with recent SARS-CoV-2 mild infection treated with intravenous thrombolysis and endovascular thrombectomy

Objective: N/A Background: Acute ischemic stroke is a major cause of disability worldwide in adults and children. It is a common disease after middle age but uncommon in the pediatric population. Disabling arterial ischemic strokes due to acute intracranial large vessel occlusion within 3-4 weeks of SARS-CoV-2 (COVID-19) infection have been described. Design/Methods: N/A Results: A 15-year-old boy presented with sudden onset right-sided weakness and expressive aphasia witnessed by mother. He presented within 50 minutes of symptom onset to the regional ER facility. Around 4 weeks ago, patient had mild SARS-Cov-2 infection with flu-like symptoms and mild chest pain that worsened with exertion lasting 3-4 days. Neurological examination revealed diminished fluency, anomia, and right upper extremity drift. Initial non contrast computed tomography (CT) demonstrated hyperdense left middle cerebral artery (MCA) sign with subtle loss of gray/white matter differentiation in the left anterior insula. Aphasia and right-sided weakness worsened as he was coming back from CT 2 hours after symptom onset. Intravenous Tenecteplase was administered. CT angiography of head/neck confirmed left proximal M2 occlusion with no arterial dissection. Patient underwent successful mechanical thrombectomy. Three days later his deficits completely resolved. Transthoracic echocardiography with contrast bubble study was unremarkable. Laboratory workup demonstrated mildly low ATIII, positive Factor V Leiden screen with negative genetic testing, positive SARS coronavirus-2 IgG, mildly low PTT. Remaining coagulopathy workup was unremarkable. Conclusions: To our knowledge this is the first case of large vessel occlusion in a pediatric patient treated successfully with both intravenous thrombolysis and mechanical thrombectomy associated with recent SARS-Cov-2 infection. The AIS etiology in our case remains uncertain as abnormal laboratory findings do not explain this presentation. There is high clinical suspicion of an embolic event as possible explanation, possibly related to SARS-CoV-2 postinfectious stage.

Cardiac Arrest With Spontaneous Coronary Artery Dissection in a Young Female.

Spontaneous coronary artery dissection (SCAD) is a rare condition that has variable clinical presentations requiring a very high index of suspicion for diagnosis. We present here a case of a young female with SCAD who initially presented with chest pain and syncope, with progression to cardiac arrest.
