Intraventricular masses are a relatively rare condition ranging from asymptomatic to potentially life-threatening situations.
Herein, we report a case of a 49-year-old woman under investigation for a massive right ventricular (RV) mass who underwent complete investigation for possible differential diagnosis, in the suspect of RV tumour. Multimodality imaging with cardiac computed tomography and magnetic resonance imaging showed the presence of a massive thrombus partially obliterating the right ventricle. Surgical removal of the mass showed a large area of stratified thrombosis with an underlying area of endocardial fibrosis. The patient has been then discharged in good clinical condition and with lifetime oral anticoagulation.
Massive RV thrombosis is a rare yet potentially fatal condition. Invasive management is preferable and lifetime anticoagulation is required to reduce possible downstream thrombotic complications.

Transcatheter pulmonary valve implantation (TPVI) is an effective treatment for right ventricular outflow tract (RVOT) dysfunction. Patients affected by congenital heart disease requiring TPVI may have difficult anatomies, thus making the intervention technically demanding.
We report a case series of two patients affected by RVOT dysfunction. Both the cases were characterized by difficulty to advance the valve over the wire, which was successfully overcome by the application of the snared wire technique (SWT) to TPVI.
Various technical pitfalls and tips have been described to facilitate the delivery of the transcatheter Edwards Sapien valve in the pulmonary position. The SWT described by the authors may be a helpful tool to gain supportiveness and stability of the guidewire during the procedure.

Coronary embolism is an important non-atherosclerotic cause of acute myocardial infarction (AMI) that requires an individualized diagnostic and therapeutic approach. Although certain angiographic criteria exist that render an embolic origin likely, uncertainty remains. Optical coherence tomography (OCT) is a high-resolution intracoronary imaging technology that enables visualization of thrombus and the underlying coronary vessel wall, which may be helpful to distinguish between an atherosclerotic and non-atherosclerotic origin of AMI.
A 50-year-old male was admitted with ongoing chest pain. Eleven years ago, he underwent implantation of a mechanical aortic valve prosthesis due to degenerated bicuspid valve with normal coronaries on preoperative angiography. The electrocardiogram showed anterior ST-segment elevation. Emergent angiography revealed total occlusion of the proximal left anterior descending artery (LAD). Thrombus was aspirated along with administration of intravenous glycoprotein IIbIIIa inhibitor. Except the apical part of the LAD showing distal embolization, coronary flow was completely re-established with no evidence of significant atherosclerosis. Stents were not implanted on the basis of the OCT finding, which demonstrated at the site of occlusion a normal vessel wall without atherosclerosis that could explain an erosion or plaque rupture event. Transoesophageal echocardiography confirmed a floating structure in the left ventricular outflow tract, suggesting that an embolus originating from the prosthetic aortic valve obstructed the LAD. The international normalized ratio 2 days prior to presentation measured 1.9.
This case illustrates the utility of OCT to rule out the atherosclerotic aetiology of myocardial infarction and to avoid unnecessary stenting.

The anomalous origin of one pulmonary artery is a rare malformation, which so far has mainly been found as an anomalous origin from a different site of the aorta, accounting for 0.12% of all congenital heart diseases. This case report introduced a very rare case of the anomalous origin of one pulmonary artery which had never reported in the clinic.
A 2-year-old boy with a 6-month history of shortness of breath and recurrent respiratory infection, was diagnosed left pulmonary artery (LPA) directly arising from the right ventricle by transthoracic echocardiography and multidetector computed tomography without a deletion in the region of 22q11. Eventually, the LPA was further conformed that arised from the right ventricle during the operation, and was corrected with a well clinical outcome.
The surgical technique for repair of this anomalous LPA was not difficult in our case. However, the embryonic development of the present case still could not be completely explained by the current embryologic postulates since it was a new malformation that never reported. Due to its rarity, there is still much to learn about the origin and development of the pulmonary arteries that possibly develop prenatally.

Cardiac myxomas are the most common benign primary cardiac tumours. The natural history of left cardiac myxomas is thought to be of slowly growing tumours. Cardiac myxomas are a heterogeneous group with a variable growth rate. They present usually with stroke, valve obstruction, or non-specific symptoms. Surgical resection is the effective treatment.
This case report describes a 56-year-old hypertensive and dyslipidaemic female, when she was admitted in January 1990, complaining of loss of appetite, aches, pains, and palpitations. selleck chemicals Her workup included a transthoracic echocardiography and transoesophageal echocardiography, which showed a left atrial mass attached to the inter-atrial septum, highly suggestive of left atrial myxoma. She was referred for surgical removal of the left atrial mass. However, she was reluctant to undergo surgery as she felt better. The patient was followed-up for almost 30 years with the left atrial mass confirmed as left atrial myxoma by cardiac magnetic resonance imaging. The left atrial mass became smaller in size and more calcified.
Cardiac myxomas are a group of heterogeneous tumours, thought to be slowly growing. The growth rate of cardiac myxomas prior to diagnosis is not well known, as the vast majority is treated with surgical resection immediately after diagnosis. Our case showed the natural progression of an unoperated smooth-surfaced left atrial myxoma followed-up for almost 30 years, which slowly became smaller and more calcified.

The aim was to report results from PERSIST, a real-life, observational, prospective cohort study of CT-P13, an infliximab (IFX) biosimilar, for treatment of patients with RA, AS or PsA who were biologic naïve or switched from an IFX reference product (IFX-RP; Remicade).
Adult patients were recruited during usual care at 38 sites in Europe and Canada and enrolled by their physicians after meeting eligibility criteria according to the country-approved label for CT-P13. Primary outcomes were to determine drug utilization and treatment persistence and to assess safety. Patients were followed for up to 2 years. Data were analysed and reported descriptively.
Of 351 patients enrolled, 334 were included in the analysis (RA, 40.4%; AS, 34.7%; PsA, 24.9%). The safety analysis set comprised all 328 patients treated with CT-P13. The majority (58.2%) of patients received CT-P13 monotherapy, most (72.6%) by dosing every 6 or 8 weeks. The mean treatment persistence was 449.2 days; 62.3% of patients completed 2 years of treatment. In all, 214 treatment-emergent adverse events (TEAEs) were reported in 38.4% of patients. Most TEAEs were of mild or moderate intensity; 13 were severe. The most commonly reported TEAEs were drug ineffective (9.5%) and infusion-related reactions (5.2%). The most frequently reported infection-related TEAEs were upper respiratory tract infections (3.0%), nasopharyngitis (2.1%) and bronchitis (1.5%). No patients experienced tuberculosis.
Drug utilization and treatment persistence with CT-P13 were consistent with historical reports of IFX-RP in this patient population. Safety findings did not identify new concerns for CT-P13 in the treatment of patients with RA, AS or PsA.

ClinicalTrials.gov NCT02605642.Novel mRNA and vector-based covid-19 vaccinations have shown high efficacy in preventing symptomatic COVID-19 infections. Compared with the number of performed vaccinations, rates of severe side effects seem low. Rare prothrombotic coagulation disorders with suspected association to ChAdOx1 nCoV-19 (AstraZeneca) have been reported. These cases have gathered considerable media attention and caused a temporary pause of usage of the AstraZeneca vaccine in Europe and several other countries and are currently discussed as vaccine-induced immune thrombotic thrombocytopenia (VITT). However, hemorrhagic complications from ChAdOx1 nCoV-19 vaccination have also been reported but, so far, received less public attention despite considerable potential for life-threatening complications. Here we present a case of severe immune thrombocytopenia after ChAdOx1 covid-19 vaccination and its successful primary management.
Emicizumab, a bispecific antibody factor VIII mimetic, is approved for prophylaxis in hemophilia, and has different risks and side effects compared to factor VIII products.
To better understand the early impact of emicizumab on our patients at the University of Colorado Hemophilia and Thrombosis Center (UCHTC), we evaluated adverse reactions, factor prophylaxis overlap, and bleeding rates after starting emicizumab through a quality improvement project.
A retrospective chart review and structured phone interview were conducted from June to September 2019 for all patients who had started emicizumab at the UCHTC. Data about emicizumab dosing, reactions, bleeding events, and bleeding treatment were collected in 68 children and adults (aged 0.55-79.8years, on emicizumab a median 213days; range, 51-1229days) with hemophilia A (35.3% with past or current inhibitor).
Adverse reactions were primarily skin reactions, with no anaphylactic reactions or thrombosis. Bleeding events, defined as pain or swelling treated with factor or supportive measures, demonstrated wide variability, with 25 of 68 experiencing zero bleeds and 5 of 68 experiencing >8 bleeds per year.
