RESUMO

Atrial fibrillation (AF) is a major risk factor for ischemic stroke, accounting for more than 37 million cases worldwide. In AF, the left atrial appendage (LAA) is the most common site of thrombus formation, and its ligation/closure with the WATCHMAN device is a good alternative to long-term oral anticoagulation, especially in patients with contraindications to warfarin. However, the implantation procedure is associated with various risks and complications. A short-term anticoagulant and antithrombotic administration are essential after implantation. However, no consensus has been reached on the optimal regimen. The WATCHMAN device is non-inferior to warfarin and is a safe alternative for the prevention of stroke and systemic embolization related to non-valvular atrial fibrillation (NVAF). Important procedure-related complications include pericardial effusion (PE), device embolization, procedure-related ischemic stroke, and device-related thrombosis (DRT) formation. It is essential to optimize post-implantation therapy according to individual patient bleeding risk, DRT formation, and contraindication to direct oral anticoagulants (DOACs). Recent studies have also shown that DOACs are a convenient and non-inferior substitute for warfarin. Furthermore, patients with absolute contraindications to OACs/DOACs can only be managed with dual antiplatelet therapy (DAPT). Transesophageal echocardiography (TEE) should be used to assess residual peridevice flow and possible DRT formation at days 45 and 12 months. Low molecular weight heparin (LMWH) and OAC are excellent choices for DRT treatment if detected. This review summarizes the most important complications of the WATCHMAN device in the existing literature and discusses various anticoagulation strategies and challenges post-implementation.

RESUMO

Despite the contemporary techniques and devices available for invasive cardiology procedures, the current diagnostic, and interventional modalities have many shortcomings. As a contemporary cross-disciplinary technique, nanotechnology has demonstrated great potential in interventional cardiology practice. It has a pivotal role in detecting sensitive cardiac biomarkers, nanoparticle-enhanced gadolinium (Gd) contrast to enhance the detection of atherosclerotic cardiovascular disease (ASCVD), and multimodal imaging like including optical coherence tomography (OCT)/infrared luminescence (IR) for coronary plaque characterization. Furthermore, in invasive cardiology, the potential benefit is in miniaturized cardiac implantable electronic devices (CIEDs), including leadless pacemakers and piezoelectric nanogenerators to self-power symbiotic cardiac devices. Nanoparticles are ideal for therapeutic drug delivery systems for atherosclerotic plaque regression, regeneration of fibrotic cardiomyocytes, and disruption of bacterial biofilm to enhance and prolong the effects of antimicrobial agents in infective endocarditis (IE). In summary, nanotechnology-assisted therapies can overtake conventional invasive cardiology and expand the horizon of microtechnology in the diagnosis and treatment of CAD in the foreseeable future.

RESUMO

INTRODUCTION: Ramadan is a month of obligatory fasting observed by the majority of 2 billion Muslims living around the globe. The guidelines for 'risk-free' fasting exist for chronic diseases, including diabetes mellitus, but recommendations for cardiovascular disease (CVD) patients are deficient due to the paucity of literature. AREAS COVERED: Databases were screened to find relevant studies for an evidence-based consensus regarding the risk stratification and management of CVD. Using practical guidelines of the European Society of Cardiology (ESC), we categorized patients into low-, moderate-, and high-risk categories and proposed a pre-Ramadan checklist for the assessment of cardiac patients before fasting. Regular moderate-intensity exercise is recommended for most cardiac patients, which has been demonstrated to provide an anti-inflammatory and antioxidant effect that improves immune function. EXPERT OPINION: In Ramadan, many physiological changes occur during fasting, which brings about a balanced metabolic homeostasis of the body. In addition, Ramadan fasting is a nonpharmacologic means of decreasing CV risk factors. As Islam exempts Muslims from fasting if they are unwell; therefore, patients with the acute coronary syndrome (ACS), advanced heart failure (HF), recent percutaneous coronary intervention (PCI), or cardiac surgery should avoid fasting.

RESUMO

INTRODUCTION: Dengue is one of the most important viral diseases globally and a majority of symptomatic infections result in a benign course. However, a small number of patients develop severe manifestations, including the cardiovascular (CV) manifestations, including myocardial impairment, arrhythmias, and fulminant myocarditis. AREAS COVERED: Electronic databases, including PubMed/MEDLINE, EMBASE, Scopus, and CINAHL were searched for articles incorporating CV manifestations of dengue fever (DF). EXPERT OPINION: Included studies involved 6,773 patients, and 3,122 (46.1%) exhibited at least one cardiac manifestation. Electrocardiogram (ECG) abnormalities (30.6%) included sinus bradycardia (8.8%), nonspecific ST-T changes (8.6%), ST depression (7.9%), and T-wave inversion (2.3%). Mechanical sequelae were present in 10.4%, including left ventricular (LV) systolic dysfunction (5.7%), and myocarditis (2.9%). Pericardial involvement was noted as pericarditis (0.1%), pericardial effusion (1.3%), and pericardial tamponade (0.1%). Apart from that, the cardiac injury was depicted through a rise in cardiac enzymes (4.5%). The spectrum of CV manifestations in dengue is broad, ranging from subtle ST-T changes to fulminant myocarditis and the use of contemporary techniques in diagnosing cardiac involvement should be employed for rapid diagnosis and treatment.
