Prolactin Inhibition to Treat Postpartum Arrhythmic Storm.

Postpartum electrical storm due to torsade de pointes is a rare but life-threatening condition. The uniqueness of this case lies in the use of cabergoline to suppress postpartum ventricular arrhythmias in absence of heart disease. Timely multidisciplinary management is crucial to achieve final diagnosis, deliver proper treatment and improve prognosis.

How to deal with vessel diameter mismatch in left main bifurcation stenting.

Left main coronary artery percutaneous coronary intervention is particularly complex when stenting across the distal bifurcation is required in the presence of a diameter mismatch between the proximal main and distal branches. A suboptimal procedural result increases the risk of thrombosis and restenosis. Considering the paucity of data published on this topic, our objective was to provide technical solutions to deal with this complex anatomy. We described four cases showing the use of devices and techniques which allowed us to overcome a diameter discrepancy between adjacent coronary segments: (1) self-expanding nitinol stent; (2) stent platform with noteworthy expansion capacity; (3) the 'extended skirt' technique; (4) the 'trouser-leg' technique. In conclusion, the use of specific strategies and devices allows a safe and effective approach to be used to perform treatment that respects the coronary anatomy, and to optimize percutaneous coronary intervention results in complex scenarios.

[The shockwave: an ace in the hole?] / Lo shockwave: un asso nella manica?

In patients with severe calcified coronary lesions, angioplasty procedures are associated with significant technical problems and a higher rate of complications. Nowadays, intravascular lithotripsy represents a safe and effective system for the treatment of calcified coronary stenosis before stent deployment. In this article, we report three complex clinical or angiographic cases in which the use of coronary lithotripsy is not yet codified. Specifically, we discuss a case of stent underexpansion after primary angioplasty, a case of acute myocardial infarction due to left main subocclusive stenosis complicated by cardiogenic shock and a case of severely calcified plaque in a venous bypass graft. In these three cases, the use of shockwave was essential to ensure an optimal procedural result, in the absence of significant adverse clinical events.

Treatment and Outcome of Patients With Coronary Artery Ectasia: Current Evidence and Novel Opportunities for an Old Dilemma.

Coronary artery ectasia (CAE) is defined as a diffuse or focal dilation of an epicardial coronary artery, which diameter exceeds by at least 1. 5 times the normal adjacent segment. The term ectasia refers to a diffuse dilation, involving more than 50% of the length of the vessel, while the term aneurysm defines a focal vessel dilation. CAE is a relatively uncommon angiographic finding and its prevalence ranges between 0.3 and 5% of patients undergoing coronary angiography. Although its pathophysiology is still unclear, atherosclerosis seems to be the underlying mechanism in most cases. The prognostic role of CAE is also controversial, but previous studies reported a high risk of cardiovascular events and mortality in these patients after percutaneous coronary intervention. Despite the availability of different options for the interventional management of patients with CAE, including covered stent implantation and stent-assisted coil embolization, there is no one standard approach, as therapy is tailored to the individual patient. The abnormal coronary dilation, often associated with high thrombus burden in the setting of acute coronary syndromes, makes the interventional treatment of CAE patients challenging and often complicated by distal thrombus embolization and stent malapposition. Moreover, the optimal antithrombotic therapy is debated and includes dual antiplatelet therapy, anticoagulation, or a combination of them. In this review we aimed to provide an overview of the pathophysiology, classification, clinical presentation, natural history, and management of patients with CAE, with a focus on the challenges for both clinical and interventional cardiologists in daily clinical practice.

Balloon aortic valvuloplasty for urgent treatment of severe aortic stenosis during coronavirus disease 2019 pandemic: a case report.

An 86-year-old man affected by severe aortic stenosis (AS) was referred to our institution owing to decompensated heart failure. Three months before, the patient was scheduled for transcatheter aortic valve implantation (TAVI), which was postponed owing to the coronavirus disease 2019 (COVID-19) outbreak. Owing to COVID-19 suspicion, he underwent nasopharyngeal swab and was temporarily isolated. However, the rapid deterioration of clinical and haemodynamic conditions prompted us to perform balloon aortic valvuloplasty (BAV) as bridge to TAVI. The patient's haemodynamics improved; and the next day, the reverse transcriptase-polymerase chain reaction for COVID-19 was negative. At Day 5, he underwent TAVI procedure. Subsequent clinical course was uneventful. During COVID-19 pandemic, the deferral of TAVI procedure should be assessed on a case-by-case basis to avoid delay in patients at high risk for adverse events. BAV may be an option when TAVI is temporarily contraindicated such as in AS patients suspected for COVID-19.

Italian Society of Interventional Cardiology (GISE) position paper for Cath lab-specific preparedness recommendations for healthcare providers in case of suspected, probable or confirmed cases of COVID-19.

COVID-19 pandemic raised the issue to guarantee the proper level of care to patients with acute cardiovascular diseases and concomitant suspected or confirmed COVID-19 and, in the meantime safety and protection of healthcare providers. The aim of this position paper is to provide standards to healthcare facilities and healthcare providers on infection prevention and control measures during the management of suspected and confirmed cases of 2019-nCoV infection accessing in cath-lab. The document represents the view of the Italian Society of Interventional Cardiology (GISE), and it is based on recommendations from the main World and European Health Organizations (WHO, and ECDC) as well as from the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI).

[A strategic roadmap of the Italian Society of Interventional Cardiology (SICI-GISE) to ensure patient's access to appropriate treatment]. / Roadmap strategica della Società Italiana di Cardiologia Interventistica (SICI-GISE): garantire ai pazienti le terapie appropriate.

In comparison with the international scenario, in Italy the penetration of several important scientific and technological innovations in the field of cardiovascular intervention appears to be inadequate both in terms of number of patients treated with respect to the actual need, and inhomogeneity between the different geographical areas of the country. One of the main institutional objectives of the Italian Society of Interventional Cardiology (SICI-GISE) is to develop a roadmap to guarantee homogeneous access throughout the whole national territory to treatments that are recommended by the major international guidelines. The present document focuses on four main areas of cardiovascular intervention: (i) transcatheter treatment of aortic valve stenosis, (ii) percutaneous mitral valve repair, (iii) prevention of cardioembolic stroke through percutaneous left atrial appendage occlusion in patients with non-valvular atrial fibrillation, (iv) optimization of coronary revascularization with the aid of the functional study of coronary lesions. The purpose of this document is to describe the clinical profile and the economic impact of the aforementioned methods, the current clinical, organizational and management barriers to treatment access in the national territory and the possible solutions for overcoming the aforementioned barriers.
