Tricuspid insufficiency has long been considered an entity with low prognostic importance and associated with symptoms and signs only secondarily to left heart pathology. Scientific research in recent years has debunked this myth, demonstrating a key role in determining symptoms and signs of right heart failure, even in advanced stages. In parallel, advances in transcatheter technologies have opened up treatment options even for patients with increased surgical risk, who were previously excluded from traditional surgical options, with increasingly convincing results in reducing symptoms and improving the quality of life of our patients. The contemporary challenge is to translate these messages into everyday clinical practice and to encourage the centralization of patients in centers that currently have the expertise for feasibility evaluation and subsequent treatment. In this Review, we will analyze the most recent evidence on the pathophysiology and diagnosis of tricuspid insufficiency, the latest recommendations from European guidelines, and we will try to illustrate the most common technologies for percutaneous treatment and the abundant evidence supporting them.

The aim of this review is to explore the available evidence concerning the relationship between the different parameters of the complete blood count, its pathophysiological changes and cardiovascular disease, specifically focusing on the acute ischemic setting. Erythrocytes, leukocytes and platelets undergo significant and more or less durable changes over time in response to conditions of systemic inflammatory, infectious and neoplastic disease. This is the reason why blood cell count parameters can (and should) be implemented in the global assessment of the patient with acute coronary syndrome.From the literature review it emerges that anemia and thrombocytopenia have an independent negative prognostic role in the medium and long term, being markers of the overall frailty of patients with ischemic heart disease. On the other hand, essential thrombocythemia and polycythemia vera, two chronic myeloproliferative neoplasms, are characterized by an important increase in thrombotic risk. Both conditions are given a brief description for the particular importance of the close collaboration between cardiologists and hematologists in the diagnosis and treatment of these diseases in the context of ischemic heart disease.

The term MINOCA (myocardial infarction with non-obstructive coronary arteries) defines acute myocardial infarction with angiographic evidence of no significant coronary artery stenosis. Heterogeneous diseases are labelled as MINOCA. Incidence and epidemiological aspects differ on the basis of etiological causes. MINOCA include plaque (causing <50% stenosis) rupture or erosion, coronary embolism and dissection, and coronary artery spasm. Diagnosis may require multiple diagnostic tools, including cardiac imaging or provocative tests, in addition to standard coronary angiography, according to clinical suspicion. Cardiac magnetic resonance plays a key role in confirming the diagnosis and excluding other diseases with similar clinical presentation. Prognosis is not as benign as previously thought, on the opposite it is characterized by morbidity and mortality rates similar to other forms of myocardial infarction. Once the causative mechanism has been identified, appropriate therapy can be delivered.

Background: The aim of this study was to report clinical outcomes in patients treated with paclitaxel-coated balloons (PCB) for in-stent restenosis (ISR) in both bare metal (BMS) and drug-eluting stent (DES)., Methods: Between May 2009 and December 2015, we treated 155 ISR in 140 patients. At recruitment, 35% of patients had diabetes. Among the lesions, 125 were first occurrence (55 within BMS and 70 within DES) and 30 recurrent; 24 ISR were multi-metal layered. Mean reference diameter was 2.79 ± 0.52 mm and mean lesion length 13.2 ± 7.1 mm. PCB use included 32 Dior I, 97 InPact Falcon, 18 Panthera Lux, and 8 Restore DEB., Results: At a median follow-up of 442 days, we observed 18 target lesion revascularizations (TLR), one myocardial infarction, 3 cardiac deaths, and 5 non-cardiac deaths. TLR occurrence differed according to type of ISR (4% within BMS, 14% within DES, 28% within recurrent ISR; p<0.05). TLR was associated with PCB type (35% Dior I, 9% InPact Falcon, 0% Panthera Lux and Restore DEB; p<0.05). Multivariable analysis revealed that first-generation PCB without a carrier (hazard ratio [HR] 2.50, 95% confidence interval [CI] 0.96-6.50; p=0.06) and recurrent ISR (HR 7.76, 95% CI 1.56-38.66; p=0.01) correlated with subsequent TLR., Conclusions: Our results confirm the safety and efficacy of PCB for ISR treatment both within BMS and DES. PCB type and recurrent ISR correlate with subsequent TLR.

Background: Follow-up modalities for patients undergoing percutaneous coronary intervention (PCI) are not well defined and standard protocols have been not established. The purpose of this study was to assess: a) the frequency and patterns of cardiology visits, echocardiographic examinations and stress tests after PCI in clinical practice; b) the impact of a multidisciplinary protocol of long-term follow-up after PCI shared with general practitioners on the appropriateness and reduction in healthcare costs., Methods: A total of 780 patients who underwent PCI in 2010 in two Italian hospitals were analyzed. The number of cardiological examinations (total, routine and clinically driven) performed during 2 years of follow-up were recorded and stratified according to the patient's risk profile. The latter was defined according to the multidisciplinary protocol. In addition, a simulation of the spread between provided and necessary tests (according to the multidisciplinary protocol) was carried out., Results: The mean number of cardiological examinations per patient provided during follow-up was 5, of which 4.4 were routine tests in asymptomatic patients. Routine tests were performed more frequently in patients at low risk compared to those at higher risk. By applying the multidisciplinary protocol to the case mix and by merging clinical visit and stress test or echocardiographic examination, a reduction of 0.87 tests per patient/year would be expected. This reduction would result in a 39% decrease in follow-up examinations in this specific clinical setting., Conclusions: This observational study demonstrates that unnecessary cardiological clinical and functional tests are often performed in long-term follow-up of patients submitted to PCI. The application of a standard protocol of follow-up shared with general practitioners may help avoiding unnecessary consultations, thus reducing healthcare costs.

Coronary artery perforation is a rare but potentially fatal complication. Therefore, it is crucial for interventional cardiologists to have knowledge of this condition and what management strategies are available, particularly in the case of procedures with a high level of complexity. Notwithstanding this, even simple procedures are not immune to serious complications, as described in this case report where coronary angioplasty was complicated by left anterior descending artery perforation with cardiac tamponade, giving rise to multiple complications of difficult management. The case presented here also provides the opportunity to investigate the optimal duration of dual antiplatelet therapy after implantation of drug-eluting stents, a topic much debated in recent years.
