Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included...

MicroRNAs (miRs, miRNAs) are known to have a part in various human illnesses, such as those related to the heart. One particular miRNA, miR-155, has been extensively studied and has been found to be involved in hematopoietic lineage differentiation, immunity, viral infections, inflammation, as well as vascular remodeling. These processes have all been connected to cardiovascular diseases, including heart failure, diabetic heart disease, coronary artery disease, and abdominal aortic aneurysm. The impacts of miR-155 depend on the type of cell it is acting on and the specific target genes involved, resulting in different mechanisms of disease...

BACKGROUND: Thoracoabdominal aortic aneurysms (TAAAs) are rare but complicated aortic pathologies that can result in high morbidity and mortality. The whole-aorta hemodynamic characteristics of TAAA survivors remains unknown. This study sought to obtain a comprehensive view of flow hemodynamics of the whole aorta in patients with TAAA using four-dimensional flow (4D flow) magnetic resonance imaging (MRI). METHODS: This study included patients who had experienced TAAA or abdominal aortic aneurysm (AAA) and age- and sex-matched volunteers who had attended China Hospital from December 2021 to December 2022 in West...

Pulmonary Artery Aneur ysm (PAA), whether congenital or acquired, is a rare diagnostic find ing com pare d to aor tic aneur ysms. There have been fe w cases where PA As were documented as a complication of untreated Patent Ductus Ar teriosus (PDA) due to long-standing Pulmonary Arterial H ypertension (PAH). However, it is quite rare for a case of PAA to be reported with co-existing PDA without PAH. This report highlights a case of a five -year-old girl who was presented with palpitations, easy fatigability, fever, c yanos is, and vomiting...

Pulmonary artery pseudoaneurysms (PAPs) are uncommon, yet they frequently result in hemoptysis and are associated with a poor prognosis. We report a case of an 87-year-old male patient. Initially, he was admitted to a previous hospital, and diagnosed with a lung abscess in the left lower lobe. On the second hospital day, he developed hemoptysis. A contrast-enhanced chest computed tomography (CT) identified an infectious pulmonary artery pseudoaneurysm. On the ninth hospital day, pulmonary artery coil embolization was successfully performed, significantly improving the patient's condition...

Giant septic pulmonary artery aneurysms (PAAs) are rare but important entities, with few cases having been reported worldwide. Early diagnosis and prompt treatment are crucial in the management of such cases. We report a 56-year-old female patient presenting with fatigue, nausea and vomiting who was first diagnosed with diabetic ketoacidosis (DKA) and developed life-threatening giant infectious PAA secondary to SARS-CoV-2 infection and Actinomyces odontolyticus sepsis. The patient did not develop any specific symptoms, and enhanced computed tomography (CT) revealed a massive PAA of 5...

BACKGROUND: A coronary artery aneurysm is a dilation exceeding 1.5 times the diameter of the patient's largest coronary vessel. They are rare, varying in prevalence between 1.4 and 4.9%. Additionally, they carry a high risk of potential complications, including thrombosis and myocardial infarction, with a risk of rupture. We present an interesting case of a patient with initial imaging suggesting a mass in the right ventricle. CASE SUMMARY: This patient initially presented with acute hypoxic respiratory failure related to pulmonary oedema...

BACKGROUND: Enterprise stent was approved for the treatment of wide-necked intracranial aneurysms. However, it has been widely used in the endovascular treatment of intracranial artery stenosis, which is still controversial. The purpose of this study was to evaluate the safety and efficiency of the Enterprise stent in the endovascular treatment of intracranial artery stenosis disease. METHODS: We conducted a retrospective case series of 107 patients with intracranial artery stenosis who received Enterprise stent implantation at Nanjing Drum Tower Hospital from January 2020 to December 2022...

A 30-year-old woman with ankylosing spondylitis was referred to our clinic with abnormal fetal echocardiography findings, including ascending aortic dilatation, giant main pulmonary artery aneurysm, and aortic and pulmonary valve stenosis at 22 weeks of gestation. The full-term male neonate was born by cesarean section and was transferred to the cardiac intensive care unit soon after delivery for respiratory distress with low percutaneous oxygen saturation. Based on cardiovascular and genetic analysis findings, the patient was diagnosed with Marfan syndrome...

Background : Takayasu's arteritis is a rare type of vasculitis with severe complications like stroke, ischemic heart disease, pulmonary hypertension, secondary hypertension, and aneurysms. Diagnosis is achieved using clinical and angiographic criteria. Treatment is medical and surgical, but unfortunately, the outcome is limited. Case presentation : A 34-year-old Caucasian woman had an ischemic stroke (2009). She was diagnosed with Takayasu's arteritis and received treatment with methotrexate, prednisolone, and antiplatelet agents, with a mild improvement in clinical state...

Dilated cardiomyopathy (DCM) is the most common childhood cardiomyopathy and is associated with considerable early mortality. Heart transplantation is often the only viable life-saving option. Pulmonary artery banding (PAB) has been recently proposed as a bridge or alternative to transplantation for DCM. In our cohort, PAB was selectively addressed to heritable DCM or DCM with congenital left ventricle aneurysm (CLVA). This study aimed to describe the clinical evolution and left ventricle reverse remodeling (LVRR) over time (6 months and 1 year after surgery)...

Clazosentan, a potent selective endothelin receptor subtype A antagonist, has been demonstrated to be effective in preventing cerebral vasospasms after subarachnoid hemorrhage. We report the successful management of respiratory failure due to pulmonary edema associated with clazosentan, with a hemodynamic monitoring system. A 49-year-old Japanese man underwent emergency clipping for a right internal carotid-posterior communicating artery aneurysm. The surgery and general anesthesia for the rupture proceeded with no complications...

Cardiovascular risk factors are the cause of atherosclerotic disease, which can involve all the elastic and muscolo-elastic arteries. The etiopathogenesis of atherosclerosis is multifactorial since genetics, lifestyle, and comorbidities can be simultaneously involved. Clinical manifestations can be heterogeneous and include myocardial infarction, stroke, aortic aneurysms, renal artery stenosis, renal insufficiency, peripheral artery disease, etc. Currently, 70% of clinical events cannot be prevented with available drug therapy, statins included, and at least 10% of coronary events occur in apparently healthy individuals in the absence of major traditional risk factors...

INTRODUCTION: Pulmonary artery aneurysms encompass a wide range of presentations and forms. Mycotic aneurysms represent a particular subset of focal dilatation of the vessel wall with high morbidity and mortality rates. Herein, we report the case of a 32 year old patient, with a prior history of ventricular septal defect presenting with a mycotic pulmonary artery aneurysm associated with infective endocarditis and septic emboli. CASE PRESENTATION: We present the case of a 32 year old male with known history of congenital ventricular septal defect presented to the emergency department with signs of sepsis and dyspnea...

A young female patient presented with complaints of breathlessness and palpitations since 2 years. On clinical examination, there was a loud continuous murmur at the right sternal border.Transthoracic echocardiography and colour Doppler showed a tunnel-like structure originating from the aneurysmal right coronary sinus and opening into the right atrium with left to right shunt. Coronary angiography revealed a large tunnel beginning in right coronary sinus and terminating in the right atrium and right coronary artery (RCA) was seen originating from the tunnel...

A 73-year-old female presented with exertional dyspnea and was found to have a coronary artery to pulmonary artery fistula with 2 sequential giant aneurysms. Her chest radiograph showed a mass above the cardiac silhouette.

In individuals with Marfan Syndrome (MFS), fibrillin-1 gene (FBN1) mutations can lead to vascular wall weakening and dysfunction. The experimental mouse model of MFS (Fbn1C1041G/+ ) has been advantageous in investigating MFS-associated life-threatening aortic aneurysms. It is well established that the MFS mouse model exhibits an accelerated-aging phenotype in elastic organs like the aorta, lung, and skin. However, the impact of Fbn1 mutations on the in vivo function and structure of various artery types with the consideration of sex and age, has not been adequately explored in real-time and a clinically relevant context...

INTRODUCTION: Pulmonary artery aneurysm (PAA) is a rare abnormality of pulmonary vasculature. It can be idiopathic or secondary to various pathologies, frequently with multiple factors leading to its formation. We report the case of a man with concomitant sarcoidosis and PAA. CASE DESCRIPTION: A 75-year-old male with a diagnosis of pulmonary sarcoidosis was referred to the Cardiology department due to heart failure with reduced left ventricular ejection fraction (LVEF)...
