A Rare Case of Cerebral Venous Thrombosis and Disseminated Intravascular Coagulation Temporally Associated to the COVID-19 Vaccine Administration
Globally, at the time of writing (20 March 2021), 121.759.109 confirmed COVID-19 cases have been reported to the WHO, including 2.690.731 deaths. Globally, on 18 March 2021, a total of 364.184.603 vaccine doses have been administered. In Italy, 3.306.711 confirmed COVID-19 cases with 103.855 deaths have been reported to WHO. In Italy, on 9 March 2021, a total of 6.634.450 vaccine doses have been administered. On 15 March 2021, Italian Medicines Agency (AIFA) decided to temporarily suspend the use of the AstraZeneca COVID-19 vaccine throughout the country as a precaution, pending the rulings of the European Medicines Agency (EMA). This decision was taken in line with similar measures adopted by other European countries due to the death of vaccinated people. On 18 March 2021, EMA’s safety committee concluded its preliminary review about thromboembolic events in people vaccinated with COVID-19 Vaccine AstraZeneca at its extraordinary meeting, confirming the benefits of the vaccine continue to outweigh the risk of side effects, however, the vaccine may be associated with very rare cases of blood clots associated with thrombocytopenia, i.e., low levels of blood platelets with or without bleeding, including rare cases of cerebral venous thrombosis (CVT). We report the case of a 54-year-old woman who developed disseminated intravascular coagulation (DIC) with multi-district thrombosis 12 days after the AstraZeneca COVID-19 vaccine administration. A brain computed tomography (CT) scan showed multiple subacute intra-axial hemorrhages in atypical locations, including the right frontal and the temporal lobes. A plain old balloon angioplasty (POBA) of the right coronary artery was performed, without stent implantation, with restoration of distal flow, but with persistence of extensive thrombosis of the vessel. A successive thorax angio-CT added the findings of multiple contrast filling defects with multi-vessel involvement: at the level of the left upper lobe segmental branches, of left interlobar artery, of the right middle lobe segmental branches and of the right interlobar artery. A brain magnetic resonance imaging (MRI) in the same day showed the presence of an acute basilar thrombosis associated with the superior sagittal sinus thrombosis. An abdomen angio-CT showed filling defects at the level of left portal branch and at the level of right suprahepatic vein. Bilaterally, it was adrenal hemorrhage and blood in the pelvis. An evaluation of coagulation factors did not show genetic alterations so as the nasopharyngeal swab ruled out a COVID-19 infection. The patient died after 5 days of hospitalization in intensive care.
Integrating remote CIED monitoring into heart failure care: evidence, challenges, and opportunities
Remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) has evolved from simple device integrity checks to a cornerstone of personalized heart failure (HF) management. By enabling early detection of subclinical deterioration, CIED-based RM supports proactive clinical interventions, potentially reducing hospitalizations and improving outcomes. Multiparametric algorithms such as HeartLogic, TriageHF, and HeartInsight integrate hemodynamic and arrhythmic parameters to predict HF events with good sensitivity. However, despite increasing evidence of clinical and economic benefits, RM implementation remains inconsistent due to heterogeneous protocols, data latency, and inadequate reimbursement structures. This review summarizes current evidence, operational challenges, and future opportunities for integrating remote CIED monitoring into comprehensive HF care pathways, highlighting the role of artificial intelligence and the need for standardized workflows and reimbursement models.
A more-Comers populAtion trEated with an ultrathin struts polimer-free Sirolimus stent: an Italian post-maRketing study (the CAESAR registry)
The use of contemporary drug-eluting stents (DES) has significantly improved outcomes of patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). However, concerns exist regarding the long-term proinflammatory effects of durable polymer coatings used in most DES, potentially leading to long-term adverse events. First-generation polymer-free stent technologies, such as sirolimus- and probucol-eluting stents (PF-SES), have shown an excellent safety and efficacy profile. The aim of this study was to evaluate the safety and efficacy of the new ultrathin Coroflex ISAR NEO PF-SES, in a more-comers PCI population. The CAESAR (a more-Comers populAtion trEated with an ultrathin struts polimer-free Sirolimus stent: An Italian post-maRketing study) registry is a multicenter, prospective study conducted in Italy, enrolling more-comers CAD patients undergoing PCI with the Coroflex ISAR NEO stent. Patients with left main (LM) disease, cardiogenic shock (CS), or severely reduced left-ventricular ejection fraction (LVEF) were excluded. The primary endpoint was target-lesion revascularization (TLR) at 1 year. A total of 425 patients were enrolled at 13 centers (mean age 66.9 ± 11.6 years, Diabetes mellitus 29%, acute coronary syndrome 67%, chronic total occlusion 9%). Of these, 40.9% had multivessel disease (MVD) and in 3.3% cases, the target lesion was in-stent restenosis (ISR). Clinical device success was reached in 422 (99.6%) cases. At 1 year, only two (0.5%) subjects presented ischemia-driven TLR. The 1-year rates of target vessel revascularization and MACE were 0.5% and 5.1%, respectively. Major bleeding was observed in four (1.0%) patients. In this multicenter, prospective registry, the use of a new ultrathin Coroflex ISAR NEO PF-SES in a more-comers PCI population showed good safety and efficacy at 1 year.
Rationale and design of the PARTHENOPE trial: A two-by-two factorial comparison of polymer-free vs biodegradable-polymer drug-eluting stents and personalized vs standard duration of dual antiplatelet therapy in all-comers undergoing PCI
Over the past few decades, percutaneous coronary intervention (PCI) has undergone significant advancements as a result of the combination of device-based and drug-based therapies. These iterations have led to the development of polymer-free drug-eluting stents. However, there is a scarcity of data regarding their clinical performance. Furthermore, while various risk scores have been proposed to determine the optimal duration of dual antiplatelet therapy (DAPT), none of them have undergone prospective validation within the context of randomized trials. The PARTHENOPE trial is a phase IV, prospective, randomized, multicenter, investigator-initiated, assessor-blind study being conducted at 14 centers in Italy (NCT04135989). It includes 2,107 all-comers patients with minimal exclusion criteria, randomly assigned in a 2-by-2 design to receive either the Cre8 amphilimus-eluting stent or the SYNERGY everolimus-eluting stent, along with either a personalized or standard duration of DAPT. Personalized DAPT duration is determined by the DAPT score, which accounts for both bleeding and ischemic risks. Patients with a DAPT score <2 (indicating higher bleeding than ischemic risk) receive DAPT for 3 or 6 months for chronic or acute coronary syndrome, respectively, while patients with a DAPT score ≥2 (indicating higher ischemic than bleeding risk) receive DAPT for 24 months. Patients in the standard DAPT group receive DAPT for 12 months. The trial aims to establish the noninferiority between stents with respect to a device-oriented composite end point of cardiovascular death, target-vessel myocardial infarction, or clinically-driven target-lesion revascularization at 12 months after PCI. Additionally, the trial aims to demonstrate the superiority of personalized DAPT compared to a standard approach with respect to a net clinical composite of all-cause death, any myocardial infarction, stroke, urgent target-vessel revascularization, or type 2 to 5 bleeding according to the Bleeding Academic Research Consortium criteria at 24-months after PCI. The PARTHENOPE trial is the largest randomized trial investigating the efficacy and safety of a polymer-free DES with a reservoir technology for drug-release and the first trial evaluating a personalized duration of DAPT based on the DAPT score. The study results will provide novel insights into the optimizing the use of drug-eluting stents and DAPT in patients undergoing PCI.
Efficacy of LOw-dose DObutamine Stress-Echocardiography to predict Cardiac Resynchronization Therapy Response (LODO-CRT) multicenter prospective study—Design and rationale
Although cardiac resynchronization therapy (CRT) has a well-demonstrated therapeutic effect in selected patients with advanced heart failure on optimized drug therapy, nonresponder rate remains high. The LODO-CRT is designed to improve patient selection for CRT. Design and rationale of this study are presented herein. LODO-CRT is a multicenter prospective study, started in late 2006, that enrolls patients with conventional indications for CRT (symptomatic stable New York Heart Association class III-IV on optimized drug therapy, QRS ≥120 milliseconds, left ventricular [LV] dilatation, LV ejection fraction ≤35%). This study is designed to assess the predictive value of LV contractile reserve (LVCR), determined through dobutamine stress echocardiography (defined as an LV ejection fraction increase >5 units), in predicting CRT response during follow-up. Assessment of CRT effects will follow 2 sequential phases: in phase 1, CRT response end point is defined as LV end-systolic volume reduction ≥10% at 6 months; in phase 2, both LV end-systolic volume reduction and clinical status via a clinical composite score will be evaluated at 12 months follow-up. Predictive value of LVCR will be compared to other measures, such as LV dyssynchrony measures, through adjusted multivariable analysis. For the purpose of the study, target patient number is 270 (with 95% confidence, 80% power, α ≤ .05). Enrollment should be complete by the end of 2008. The LODO-CRT trial is testing the hypothesis that LVCR assessment, using low-dose dobutamine stress echocardiography test, should effectively predict positive response to CRT both in terms of the reverse remodeling process as well as favorable long-term clinical outcome. Moreover, the predictive value of LVCR will be compared to that of conventional intra-LV dyssynchrony measures.
Three-dimensional echocardiographic and magnetic resonance assessment of the effect of telmisartan compared with carvedilol on left ventricular mass a multicenter, randomized, longitudinal study
The hypothesis that left ventricular hypertrophy regression in hypertension relates to blood pressure (BP) control and to non-antihypertensive activity of some drugs was tested by comparing the effects of telmisartan and carvedilol on 24-h mean ambulatory BP and left ventricular mass (LVM) regression, measured using three-dimensional echocardiography (3-DECHO) and magnetic resonance imaging (MRI). A total of 82 patients with mild-to-moderate hypertension and an optimal echocardiographic acoustic window were randomized to receive once-daily telmisartan 80 mg or carvedilol 25 mg for 44 weeks. Ten patients withdrew from the study because office diastolic BP remained >90 mm Hg. The 24-h mean ambulatory systolic/diastolic BP reductions were similar in both treatment groups (telmisartan, from 159.6 +/- 10.2/97.8 +/- 5.4 to 128.6 +/- 6.5/78.2 +/- 5.8 mm Hg; carvedilol, from 157.8 +/- 11.1/95.7 +/- 11.9 to 128.2 +/- 5.6/78.7 +/- 5.2 mm Hg). However, night-time and last 6-h mean BP reductions were nonsignificantly greater with telmisartan. Using 3-DE, telmisartan (P< .001) and carvedilol (P< .001) progressively reduced LVM index by 21.97 +/- 5.84 (15.7%) and 12.31 +/- 3.14 (9.1%) g/m2, respectively, at week 44. Similar magnitudes of reductions were observed using MRI (15.5% and 9.6%, respectively). Reductions in LVM index achieved with telmisartan were statistically superior to carvedilol (P< or = .001). The superior LVM regression with telmisartan versus carvedilol suggests telmisartan has a mechanism that may be beyond that of lowering BP in hypertensive patients.
Lights and shadows of long-term dual antiplatelet therapy in “real life” clinical scenarios
Dual antiplatelet therapy (DAPT) is a cornerstone of treatment for patients with acute coronary syndromes (ACS). Mounting evidences have opened the debate about the optimal DAPT duration. Considering the ACS-pathophysiology, the most recent guidelines recommend DAPT in all ACS patients for at least 12 months unless there are contraindications such as excessive risk of bleeding. Thus, it can be considered acceptable earlier discontinuation if the risk of morbidity from bleeding outweighs the anticipated benefit. On the other hand, several studies have clearly indicated that a significant burden of platelet related-events, such as stroke and new ACS might occur after this period, suggesting that potential benefits might derive by prolonging DAPT beyond 12 months (Long DAPT). Indeed, although current guidelines give some indications about patients eligible for Long DAPT, they do not embrace several real-life clinical scenarios. Thus, in such scenarios, how to decide whether a patient is eligible for Long DAPT or not might be still challenging for clinicians. This position paper presents and discusses various “real-life” clinical scenarios in ACS patients, in order to propose several possible recommendations to overcome guidelines potential limitations.
Origine anomala dell'arteria circonflessa dal seno di Valsalva destro: valutazione mediante tomografia computerizzata multistrato ed angiografia coronarica convenzionale
L’origine anomala dell’arteria circonflessa dal seno di Valsalva destro è la più frequente anomalia coronarica ed è di scarso significato clinico se non associata alla presenza di stenosi.Presentiamo il caso di una donna di 43 anni con dolore toracico atipico e test da sforzo dubbio per cardiopatia ischemica, sottoposta a tomografia computerizzata multistrato del circolo coronarico prima di altre procedure invasive. La scansione è stata effettuata con uno scanner Aquilion 16 CFX (Toshiba Medical Systems, Tokyo, Giappone) dopo la somministrazione endovenosa di mezzo di contrasto iodato. L’esame ha evidenziato la presenza di un’arteria circonflessa che originava dal seno di Valsalva destro. Il vaso anomalo, inoltre, presentava una stenosi significativa subito dopo l’origine. L’angiografia coronarica convenzionale eseguita alcuni giorni dopo confermava il reperto.La tomografia computerizzata multistrato appare affidabile ed accurata nella valutazione non invasiva delle anomalie di origine e decorso delle arterie coronarie.
Presence of left ventricular contractile reserve, evaluated by means of dobutamine stress-echo test, is able to predict response to cardiac resynchronization therapy
Introduction We evaluated whether the dobutamine stress-echo test can select responders to cardiac resynchronization therapy (CRT). Up to 50% of patients do not respond to CRT. Lack of response may be due to a significant amount of scar or fibrotic tissue at myocardial level. Methods and Results We studied 42 CRT patients. After clinical and echocardiographic evaluation, all patients underwent a dobutamine stress-echo test to assess contractile reserve. Cut-off for the test was an increase of 25% of the left ventricular ejection fraction. Patients were implanted with a CRT–defibrillator and followed up at 6 months. Cut-off for CRT response was a reduction of 15% of left ventricular end-systolic volume. Twenty-five patients responded to CRT; all of them showed presence of contractile reserve. The test showed a sensitivity of 100% and a specificity of 88%. Conclusion Contractile reserve was a strong predictive factor of response to CRT in the studied population.
