Carpal tunnel syndrome (CTS) is the most common type of entrapment neuropathy and affects approximately 1% to 5% of the general population, mostly patients older than 50 years. CTS is present in various conditions and diseases and could also be an early sign of systemic transthyretin amyloidosis (ATTR), associated with amyloid cardiomyopathy and subsequent heart failure. With advances in the treatment of cardiac amyloidosis, patient prognosis could be significantly improved with an early diagnosis. Amyloidosis represents a group of disorders characterized by the extracellular deposition of destabilized protein fragments, aggregating as amyloid fibrils, thereby leading to organ dysfunction. Among these, ATTR is a significant subgroup. This study protocol aims to explore the potential association between CTS and systemic and cardiac ATTR. The study design involves a case-control approach, with assessments including physical examination, laboratory tests, electromyography, electrocardiogram, wrist ultrasound, and scintigraphy with ^99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid (^99mTc-DPD). Histopathological analysis and genetic testing will be performed when appropriate. Statistical analysis will be conducted to evaluate the relationship between CTS and ATTR. The study seeks to contribute to a better understanding of the diagnostic and therapeutic implications of identifying ATTR in patients with idiopathic CTS (ClinicalTrials.gov identifier: NCT05409833).

Chagas disease is a systemic illness characterized by acute and chronic phases. If untreated, it can lead to dysfunction of vital organs, notably the heart, ultimately resulting in heart failure. Transmission primarily occurs through the feces of triatomine insects carrying the protozoan parasite Trypanosoma cruzi, either via a bite wound or intact mucous membranes. Diagnosis of Chagas disease involves serological tests, electrocardiographic findings, and imaging studies. A 58-year-old male patient from Peru with chronic dilated cardiomyopathy underwent evaluation at a tertiary care hospital. Given the uncertain etiology, a comprehensive diagnostic approach was adopted, emphasizing the pivotal role of cardiovascular magnetic resonance imaging and computed tomography angiography in managing chronic cardiomyopathy of Chagas disease. Leveraging these imaging modalities together could augment our ability to evaluate myocardial inflammation and tailor therapeutic strategies accordingly.

Redo surgical aortic valve replacement (SAVR) has long been the standard treatment for severe symptomatic aortic stenosis (AS) and insufficiency, but transcatheter aortic valve replacement (TAVR) has emerged as a less invasive alternative, particularly for symptomatic AS. With calcification being a primary mechanism behind structural valve degeneration, factors such as patient characteristics and the type of bioprosthetic valve play crucial roles in determining risk. Valve-in-valve TAVR (ViV TAVR) has gained prominence as a viable alternative to redo SAVR in recent years. Echocardiography plays a pivotal role in patient selection, procedural guidance, and post-procedural evaluation in ViV TAVR. From pre-procedural assessment using transthoracic and transesophageal echocardiography to intra-procedural guidance and post-procedural follow-up, echocardiography aids in ensuring procedural success and monitoring valve function. Decision-making between redo SAVR and ViV TAVR involves multidisciplinary teams considering various factors like patient risk profile, anatomical considerations, and technical feasibility. While redo SAVR remains preferred for younger patients with lower risk, ViV TAVR is increasingly considered for older patients or those with higher reoperation risks. Factors such as coronary artery obstruction risk, patient-prosthesis mismatch, and paravalvular leak guide treatment decisions. Procedural techniques in ViV TAVR have evolved to minimize complications and optimize outcomes. Factors like access route selection, valve choice, and procedural guidance techniques significantly impact procedural success. Balloon valve fracture and preventive strategies against coronary obstruction are crucial considerations during the procedure. Post-procedural evaluation involves assessing clinical and hemodynamic outcomes, with long-term studies indicating favorable results but highlighting the importance of careful evaluation of transprosthetic gradients and valve function. ViV TAVR offers promising outcomes but requires meticulous patient selection, procedural planning, and post-procedural management to ensure optimal results.

Pneumopericardium, the presence of air within the pericardial sac, is a rare but critical condition that can lead to severe complications such as tension pneumopericardium and cardiac tamponade, causing hemodynamic instability and necessitating immediate intervention. Various etiologies include congenital defects, post-surgical complications, infections, and trauma. Malignancies, such as advanced esophageal cancer or lung carcinoma, can also cause pneumopericardium via fistula formation. Multimodal imaging, including chest X-ray, echocardiography, and computed tomography (CT), is essential for diagnosis. This case report discusses a 65-year-old male with advanced pancreatic adenocarcinoma who developed pneumopericardium following the removal of a left lobe liver drainage catheter. Initial CT imaging revealed liver lesions suspicious for metastatic disease or abscess, leading to drainage procedures. Following the removal of the drainage tube, the patient experienced respiratory distress and hypotension, and computed tomography pulmonary angiogram (CTPA) revealed pneumopericardium, likely due to a fistula formed between the abscess and pericardium. Despite no echocardiographic signs of tamponade, the patient’s persistent hypotension warranted CT-guided pericardiocentesis, resulting in gradual blood pressure improvement. This case highlights the intricate interplay between malignancy, infection, and procedural complications in developing pneumopericardium. It emphasizes the need for a multidisciplinary approach and the importance of considering both the quantity and rate of air accumulation when assessing the risk of hemodynamic compromise. The patient’s hemodynamic instability and subsequent improvement following pericardiocentesis underscore the critical role of timely intervention in managing this condition.

Vascular aging is recognized as one of the hallmarks of atherosclerosis. Currently, a growing body of evidence suggests that there exists a mutual crosstalk between telomere dysfunction and mitochondrial dysmetabolism during the process of vascular senescence. This underscores the importance of comprehensively studying the molecular mediators involved in this complex and intricate connection. In pursuit of this goal, the “VICTORIA” protocol entails a prospective single-center cohort study aimed at recruiting patients undergoing coronary angiography at Niguarda Hospital in Italy. The primary objective is to explore potential associations between peripheral markers of cell aging (telomere length and mtDNA content), dysregulation of non-coding RNA [specifically lncRNA TERRA and mitochondrial microRNA (MitomiR)], and the varied presentations of ischemic heart disease (stable angina, unstable angina, NSTEMI, and STEMI). Furthermore, we aim to investigate whether these markers correlate with vulnerable plaque characteristics, as assessed by optical coherence tomography findings. Additionally, systemic levels of pro-inflammatory biomarkers and novel indicators of senescence will be assessed. Patients will be followed up at 1 year to monitor primary outcomes including mortality, myocardial infarction, stroke, unplanned revascularization, and rehospitalization. The anticipated findings of this study hold promise for advancing our understanding of the telomere-mitochondria crosstalk, potentially paving the way for novel treatment modalities and refined risk stratification approaches for acute coronary syndrome.

Pulmonary embolism (PE) is the third leading cause of cardiovascular mortality worldwide. Percutaneous mechanical thrombectomy is indicated in patients with contraindications to thrombolysis. Complications include atrial or ventricular perforation causing tamponade. We describe one case of pericardial tamponade in an elderly woman who underwent thrombectomy for acute PE. An 88-year-old woman presented with acute shortness of breath. She was tachycardic, oxygen saturation of 80% and blood pressure of 95/57 mmHg. Bedside ultrasound showed a dilated right ventricle. Electrocardiogram showed large S wave in lead I, Q wave and inverted T wave in lead III. Computed tomography (CT) angiogram of the chest revealed an extensive saddle PE. Tissue plasminogen activator was deferred given patient’s age. Full dose anticoagulation was started and she underwent a successful percutaneous thrombectomy with FlowTriever device. Two hours later, she developed severe back pain and hypotension to 88/63 mmHg. Hemoglobin dropped from 13.7 g/dL to 8.8 g/dL. CT chest angiogram showed dense pericardial effusion, likely hemopericardium, with mass effect on the heart. Bedside pericardiocentesis was attempted and converted to pericardial window given sustained hypotension. She went into cardiac arrest. Emergent thoracotomy revealed significant hemothorax. The pericardium was opened yielding a blue, globally ischemic, and non-contracting heart. Cardiac massage and intra-cardiac epinephrine attempted unsuccessfully. Percutaneous thrombectomy using the large bore design FlowTriever system has shown promising results in reducing clot burden and improving hemodynamics. Attention must be paid to life threatening complications such as cardiac tamponade which can be precipitated by using these devices.

Adventitial crosslinking is a method in current investigational stage for preventing the rupture of aortic aneurysms. It is based on the photochemical crosslinking of adventitial collagen by exposure to ultraviolet A radiation. Essentially, an adventitial top layer is generated that displays enhanced mechanical properties and imparts additional strength and stiffness to the aneurysmal wall. Looking back upon the history of aortic surgery during 1940s, the aortic film wrapping, then dubbed “cellophane wrapping”, also was a procedure employed for delaying the aneurysmal rupture. In principle, the two procedures are similar in that both result in laminar composites, although the top layers differ fundamentally from each other. This review discussed in some detail the use and clinical outcomes of the aortic wrapping with artificial films, also mentioning the contemporary procedures still grouped under this umbrella term. The focus of the review was a comparative view on two procedures, the aortic film wrapping and adventitial crosslinking. It was concluded that the methods are different in many aspects, including the mechanisms of action. In fact, the promoters of adventitial crosslinking were not aware of the prior existence of aortic film wrapping. However, the achievements of the classical wrapping, by now regarded as merely historical episodes, did not discard prior knowledge, but repurposed it in a process that led to innovative strategies.

Metabolic syndrome (MetS) is known as a non-communicable disease (NCD) that affects more and more individuals. MetS is closely related to type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), obesity and inflammation. It is associated with T2DM due to the disturbance in insulin secretion/effect, eventually leading to insulin resistance (IR). The link between MetS and CVD is due to accelerated atherosclerosis in response to chronic inflammation. This literature review was based on a search in the PubMed database. All selected articles are written in English and cover a period of approximately 10 years (January 2014 to May 2023). The first selection used MeSH terms such as: “metabolic syndrome”, “type 2 diabetes mellitus”, “obesity”, “inflammation”, and “insulin resistance” and different associations between them. Titles and abstracts were analyzed. In the end, 44 articles were selected, 4 of which were meta-analysis studies. Currently, an individual is considered to have MetS if they present 3 of the following changes: increased waist circumference, increased triglycerides (TG), reduced high-density lipoprotein cholesterol (HDL-C), increased fasting blood glucose and hypertension. We believe this can often lead to a false diagnosis. The objective of this paper is to compile what we consider to be an appropriate panel of MetS indicators. The markers that stand out in this review are the lipid profile, anti- and pro-inflammatory function and oxidative stress. Considering the research, we believe that a complete panel, to correlate the most characteristic conditions of MetS, should include the following markers: TG/HDL-C ratio, small dense low-density lipoprotein cholesterol (SdLDL-C), lipid peroxidation markers, leptin/adiponectin ratio, plasminogen activator inhibitor-1 (PAI-1), activin-A and ferritin levels. Finally, it is important to expand research on the pathophysiology of MetS and confirm the most appropriate markers as well as discover new ones to correctly diagnose this condition.
