CAD and echo

BACKGROUND: There are various ways that coronary artery disease (CAD) might present itself. Individual risk stratification for non ST-elevation-acute coronary syndrome (NSTE-ACS) patients should determine whether invasive coronary angiography and revascularization should be scheduled. AIM OF WORK: To assess the possible utility of left ventricular global longitudinal strain in the risk-stratifying process of NSTE-ACS. SUBJECTS AND METHODS: The cardiology department of Zagazig University in Egypt organized and oversaw this cross-sectional study...

BACKGROUND: Sinus of Valsalva aneurysm (SVA) is a rare but potentially life-threatening condition. Acute myocardial infarction (MI) is a rare consequence of aneurysmal dilatation of one or more sinuses of Valsalva. We present a case of an unruptured and partially thrombosed left SVA, presenting as anterior MI and congestive heart failure. CASE SUMMARY: A 55-year-old gentleman was admitted with pulmonary oedema and a late presenting ST-elevation MI with Q wave. After initial treatment on furosemide infusion, a coronary angiography showed significant stenosis in both his left main stem (LMS) and left anterior descending artery (LAD)...

We present the case of a 59-year-old African American female with end-stage renal disease (ESRD) who presented to the emergency department with chest discomfort. She had a coronary angiogram six months ago that showed no occlusive epicardial coronary artery disease. She had elevated troponin I levels and new regional wall motion abnormalities on echocardiogram. Her SARS-CoV-2 returned positive. After a multidisciplinary team approach, she underwent another coronary angiogram that showed new severe multivessel ostial lesions and a left main coronary artery aneurysm...

Giant coronary artery aneurysms (CAAs) are rare forms of coronary artery disease. An 82-year-old man presented to the hospital with generalized weakness, arm numbness, and dizziness and was found to have a multi-infarct stroke. A transthoracic echocardiogram was obtained to determine a possible cardiovascular etiology of his stroke. However, it did not reveal thrombi or vegetation; instead, it showed a ring-like structure adjacent to the tricuspid valve that appeared to be a large right atrial cyst. A transesophageal echocardiogram was performed localizing the ring-like mass near the tricuspid annulus...

BACKGROUND: Chronic kidney disease (CKD) is associated with higher incidence of cardiovascular death. Screening for coronary artery disease in asymptomatic or mildly symptomatic patients is challenging. OBJECTIVE: The aim of this study was to investigate the incremental value of resting deformation analysis in predicting positive results for myocardial ischemia during stress transthoracic echocardiography in patients with end-stage CKD. METHODS: Sixty-one patients (mean age: 62...

To compare the merits and drawbacks of three approaches for establishing a rabbit model of nonobstructive coronary microcirculatory disease, namely, open thoracic subtotal ligation of coronary arteries, ultrasound-guided cardiac microsphere injection, and sodium laurate injection. New Zealand rabbits were allocated to four groups: a normal group (Blank group), an Open-chest group (Open-chest), a microsphere group (Echo-M), and a sodium laurate group (Echo-SL), each comprising 10 rabbits. The rabbits were sacrificed 24 h after the procedures, and their echocardiography, stress myocardial contrast echocardiography, pathology, and surgical times were compared...

BACKGROUND: Coronary slow flow (CSF) can occur due to various factors, such as inflammation, small vessel disease, endothelial dysfunction, and inadequate glucose control. However, the exact pathological mechanisms behind CSF remain incompletely understood. The objective of this study was to identify the risk factors associated with slow coronary flow in individuals with Type 2 Diabetes Mellitus (T2DM) who have non-obstructive coronary artery disease (CAD) and experience CSF. METHODS: We conducted a prospective cohort study involving 120 patients with T2DM who were referred for invasive coronary angiography due to typical chest pain or inconclusive results from non-invasive tests for myocardial ischemia...

BACKGROUND: Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology that affects infants and young children but is extremely rare in neonates, especially afebrile KD. We present a case of KD without fever in a neonate and review the literature on KD in neonates. CASE PRESENTATION: A newborn female was hospitalized because her peripheral blood leukocytes increased for half a day. The admission diagnosis was considered neonatal sepsis and bacterial meningitis...

OBJECTIVE: This study aimed to investigate the predictive value of left ventricular global longitudinal strain (GLS) and left atrial reservoir strain (LARS) on adverse events in chronic coronary artery disease (CAD) patients with reduced systolic function. METHODS: A total of 192 consecutive patients clinically diagnosed with chronic CAD and left ventricular ejection fraction (LVEF) ≤ 50% were finally included. Multiple strain parameters were analyzed with speckle tracking echocardiography...

A 58-year-old male patient was admitted with chest pain and was diagnosed with coronary heart disease. He was scheduled for coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Intraoperative real-time transesophageal echocardiography (TEE) showed that the tricuspid valves were well-aligned and subtle regurgitation. Real-time TEE after separation from CPB showed severe tricuspid regurgitation and prolapsed chordae tendineae. The tricuspid chordae tendineae rupture due to a right atrial venous return cannula...

OBJECTIVE: To investigate the predictive ability of global longitudinal strain (GLS) and mechanical dispersion for coronary stenosis and provide a more reliable noninvasive method for diagnosis of obstructive coronary artery disease(OCAD). METHODS: Sixty-seven patients diagnosed with suspected CAD were included in the study. Patients with coronary stenosis greater than 50% were assigned as OCAD, while the others were assigned as non obstructive coronary artery disease(NOCAD)...

The coexistence of bicuspid aortic valve disease and coronary artery disease is well-established, but the identification of cardiac amyloidosis in this population has surged with advancing imaging techniques, introducing complexities in patient management. This case report emphasizes the pivotal role of multimodality imaging in accurately diagnosing three concurrent pathologies.

AIM: Hepatic fibrosis, a progressive scarring of liver tissue, is commonly caused by non-alcoholic fatty liver disease (NAFLD), which increases the risk of cardiovascular disease. The Fibrosis-4 (FIB-4) index is a non-invasive tool used to assess liver fibrosis in patients with NAFLD. Aortic valve sclerosis (AVS), a degenerative disorder characterized by thickening and calcification of valve leaflets, is prevalent in the elderly and associated with increased cardiovascular morbidity and mortality...

BACKGROUND: Coronary stent infections are an uncommon but deadly complication of percutaneous coronary intervention. Mortality remains as high as 40-60% even with adequate treatment. We report such an interesting case of left circumflex stent (LCX) infection and mycotic aneurysm that was successfully managed with antibiotics and surgery. CASE PRESENTATION: A middle-aged man who underwent percutaneous coronary intervention (PCI) to the left circumflex artery four weeks prior was referred as a case of pyrexia of unknown origin, not responding to antibiotics, and colchicine started for suspected Dressler syndrome...

Carmustine is an intravenous alkylating agent that inhibits DNA synthesis and protein synthesis by forming cross-links in DNA and RNA and ultimately causing cell death. We report a rare case of Takotsubo cardiomyopathy that is thought to be related to carmustine, where the patient presented with chest pain, and ST depression within 12 hours of carmustine therapy. Workup, including echocardiography, showed global hypokinesis of the left ventricle with regional variations; mid and apical anterior septum and apex were akinetic with left ventricular ejection fraction (EF) of 30%...

We report a middle-childhood girl presented with high-grade fever and headache for 4 days. Following this, the child developed mucocutaneous symptoms. She had a notable family history of autoimmune disease. Tests revealed increased inflammatory markers. On the sixth day of illness, a two-dimensonal echocardiogram showed an enlarged coronary artery, diagnosed as incomplete Kawasaki disease (KD) and treated with IVIG and aspirin.Within a week, her younger sibling, an early-childhood girl presented with features of viral prodrome, developed mucocutaneous lesions and subcutaneous oedema of limbs...

Native cardiac valves in the setting of chronic injury undergo remodeling that includes fibrous thickening and dystrophic calcification, as well as neovascularization, that result in abnormal valve function. In order to characterize the presence of neovascularization in valves, a retrospective review of 1246 sequentially reviewed native cardiac valves of all types was performed, with correlation with other histopathologic features, and clinical and echocardiographic findings. Neovascularization was present in 55...

INTRODUCTION: It remains controversial which frailty score correlates with adverse outcomes. Instead of these subjective and time consuming scores, we studied whether ultrasound guided lower extremity thickness measurements more closely are associated with adverse outcomes. METHOD: Patients undergoing gastrointestinal malignancy surgery were included as study subjects. Frailty was identified using the FRAIL scale assessment. Ultrasound measured the muscle thickness and echo intensity of the patient's upper and lower limbs...

Chest pain is a common presentation that may represent a wide variety of underlying etiologies ranging from mild self-limiting conditions to immediately life-threatening emergencies. The combination of "cardiac-sounding chest pain" and elevated troponin levels would raise suspicion of an acute ischemic event. An acute coronary syndrome is a diagnosis that may be straightforward; however, oftentimes, patients with elevated troponin levels and chest pain may bring about a state of diagnostic uncertainty...

This manuscript describes the feasibility and approach to the assessment and performance of transcatheter pulmonary valve replacement (tPVR) in patients with surgically-created "double-barrel" right ventricular outflow tracts (RVOT). Patients with tetralogy of Fallot may have coronary anomalies which prohibit the performance of traditional tetralogy of Fallot repair. In certain cases, this may necessitate the placement of a right ventricle to pulmonary artery conduit in addition to the native RVOT, which is left in situ, creating so-called "double-barrel" RVOTs...
