RESUMO

CASE SUMMARY: A 71-year-old presented at the outpatient clinic with palpitations and NYHA II functional class. 12-lead ECG exhibited Upper septal idiopathic left ventricular tachycardia (US-ILVT). Ventricular tachycardia (VT) was interrupted with Verapamil administration, no further recurrences were documented after beta-blockers therapy was started. No coronary artery stenosis were detected. The US-ILVT was successfully treated by ablating the proximal site of the left anterior fascicle (LAF), where diastolic potential (P1) and pre-systolic potential (P2) with inverted sequence were detected during the electrophysiology study (EP) study. Cardiac magnetic resonance imaging (CMR) was performed with demonstration of intramyocardial late gadolinium enhancement (LGE) at the level of middle-basal portions of interventricular septum and basal portion of infero-lateral wall and no edema detection. A single catheter implantable cardioverter defibrillator (ICD) was implanted as secondary prevention. VT has never recurred during 3 months of follow-up with remote control of ICD. DISCUSSION: To the best of our knowledge, this is the first report in which US-ILVT was associated with ventricular septal LGE, suggestive of previous myocarditis, as substrate of re-entrant circuit. Scar-related ventricular tachycardia circuit is also suggested by the evidence of a premature ventricular complex (PVC) as trigger of recurrent VT in our case.

RESUMO

Aortic stiffness is an important clinical parameter for predicting cardiovascular events. Carotid-femoral pulse wave velocity (cf-PWV) has been proposed for performing this evaluation non-invasively; however, it requires dedicated equipment and experienced operators. We explored the possibility of measuring aortic stiffness using ultrasound scans of the abdominal aorta coupled with the Bramwell-Hill equation. Healthy subjects were investigated; measurements of cf-PWV were taken by arterial tonometry and aortic systo-diastolic pressure difference was estimated using a validated model. Pulsatility of an abdominal tract of aorta was assessed by automated processing of ultrasound scans. Through a Bland-Altmann analysis, we found large biases when estimating each parameter by applying the Bramwell-Hill equation to the measured values of the other two paramters (bias, ± 1.96 SD; PWV, about 2.1 ± 2.5 m/s; pulsatility, 12 ± 14%; pressure jump, 47 ± 55 mmHg). These results indicate that the two measures are not interchangeable, and that a large part of the bias is attributable to blood pressure estimation. Further studies are needed to identify the possible sources of bias between cf-PWV and aortic pulsatility.

RESUMO

Ultrasound (US)-based measurements of the inferior vena cava (IVC) diameter are widely used to estimate right atrial pressure (RAP) in a variety of clinical settings. However, the correlation with invasively measured RAP along with the reproducibility of US-based IVC measurements is modest at best. In the present manuscript, we discuss the limitations of the current technique to estimate RAP through IVC US assessment and present a new promising tool developed by our research group, the automated IVC edge-to-edge tracking system, which has the potential to improve RAP assessment by transforming the current categorical classification (low, normal, high RAP) in a continuous and precise RAP estimation technique. Finally, we critically evaluate all the clinical settings in which this new tool could improve current practice.

RESUMO

BACKGROUND: Late-onset complications of left atrial appendage occlusion (LAAO) device procedure are anecdotal and there are no such complications reported in literature using Cardia Ultraseal (Cardia, Inc., Eagan, MN, USA). CASE SUMMARY: We report the case of a 74-year-old Caucasian man affected by paroxysmal atrial fibrillation with significant bleeding risk (familiar thrombocytopenia, macroscopic haematuria episodes during therapy with direct oral anticoagulants, HAS-BLED risk score: 4) and ischaemic risk as well (CHADSVASC score: 3). The patient was treated with LAAO device implantation for high bleeding risk. Subsequently, after 26 days from LAAO procedure, he was admitted to the emergency department for haematic cardiac tamponade. The patient was successfully treated with subxyphoidal pericardiocentesis in the acute phase, unfortunately cardiac arrest occurred during the transfer to the referral hospital for urgent cardiac surgery. Permanent neurological damage was reported and the patient died on day 28. DISCUSSION: LAAO late-onset complications are very rare and the case presented is the first case described of late-onset pericardial effusion and tamponade secondary to the Cardia Ultraseal LAAO device implantation. We present a revision of the literature regarding the occurrence of similar adverse events and discuss the hypothetical mechanism of this major complication.

RESUMO

Patent foramen ovale (PFO) is implicated in the pathogenesis of a number of medical conditions but to date only one official position paper related to left circulation thromboembolism has been published. This interdisciplinary paper, prepared with the involvement of eight European scientific societies, reviews the available evidence and proposes a rationale for decision making for other PFO-related clinical conditions. In order to guarantee a strict evidence-based process, we used a modified grading of recommendations, assessment, development, and evaluation (GRADE) methodology. A critical qualitative and quantitative evaluation of diagnostic and therapeutic procedures was performed, including assessment of the risk/benefit ratio. The level of evidence and the strength of the position statements were weighed and graded according to predefined scales. Despite being based on limited and observational or low-certainty randomised data, a number of position statements were made to frame PFO management in different clinical settings, along with suggestions for new research avenues. This interdisciplinary position paper, recognising the low or very low certainty of existing evidence, provides the first approach to several PFO-related clinical scenarios beyond left circulation thromboembolism and strongly stresses the need for fresh high-quality evidence on these topics.

RESUMO

Assessment of vascular size and of its phasic changes by ultrasound is important for the management of many clinical conditions. For example, a dilated and stiff inferior vena cava reflects increased intravascular volume and identifies patients with heart failure at greater risk of an early death. However, lack of standardization and sub-optimal intra- and inter- operator reproducibility limit the use of these techniques. To overcome these limitations, we developed two image-processing algorithms that quantify phasic vascular deformation by tracking wall movements, either in long or in short axis. Prospective studies will verify the clinical applicability and utility of these methods in different settings, vessels and medical conditions.

RESUMO

INTRODUCTION: Little is still known about the prognostic impact of incident arrhythmias in hospitalized patients with COVID-19. The aim of this study was to evaluate the incidence and predictors of sustained tachyarrhythmias in hospitalized patients with COVID-19, and their potential association with disease severity and in-hospital mortality. MATERIALS AND METHODS: This was a retrospective multicenter observation study including consecutive patients with laboratory confirmed COVID-19 admitted to emergency department of ten Italian Hospitals from 15 February to 15 March 2020. The prevalence and the type of incident sustained arrhythmias have been collected. The correlation between the most prevalent arrhythmias and both baseline characteristics and the development of ARDS and in-hospital mortality has been evaluated. RESULTS: 414 hospitalized patients with COVID-19 (66.9 ± 15.0 years, 61.1% male) were included in the present study. During a median follow-up of 28 days (IQR: 12-45), the most frequent incident sustained arrhythmia was AF (N: 71; 17.1%), of which 50 (12.1%) were new-onset and 21 (5.1%) were recurrent, followed by VT (N: 14, 3.4%) and supraventricular arrhythmias (N: 5, 1.2%). Incident AF, both new-onset and recurrent, did not affect the risk of severe adverse events including ARDS and death during hospitalization; in contrast, incident VT significantly increased the risk of in-hospital mortality (RR: 2.55; P: .003). CONCLUSIONS: AF is the more frequent incident tachyarrhythmia; however, it not seems associated to ARDS development and death. On the other hand, incident VT is a not frequent but independent predictor of in-hospital mortality among hospitalized COVID-19 patients.

RESUMO

Cryptogenic cerebral ischemia in young patients is commonly ascribed to paradoxical embolism. We report the clinical case of a young patient with cryptogenic stroke and a patent foramen ovale, undergoing percutaneous closure of atrial septal defect. Contrast transoesophageal echocardiography at the end of the procedure demonstrated massive late residual right-to-left shunt, due to the coexistence of pulmonary arteriovenous fistulas that were subsequently closed. Routinary adoption of contrast transoesophageal echocardiography at the end of patent foramen ovale closure interventions may be useful to detect early and late residual shunts. Late residual shunts may be due to pulmonary fistulas, a well-known risk factor for recurrent thromboembolic events.

RESUMO

Patent foramen ovale (PFO) is implicated in the pathogenesis of different clinical syndromes in which it plays variable roles. In 2017 and 2018, four randomized clinical trials were published, allowing for the clarification of certain issues pertaining to cryptogenic stroke. Recently, eight European scientific societies collaborated to the writing of an interdisciplinary international position paper on PFO and cryptogenic stroke, based upon best available evidence, with the aim of defining the principles needed to guide decision making. Nonetheless, a tailored approach is not suitably addressed by standard position documents, considering that decisions about optimal management of PFO patients with left circulation thromboembolism are often challenging, mostly due to comorbidities and complex clinical scenarios.A panel of Italian cardiology experts gathered under the auspices of the Italian Society of Interventional Cardiology (SICI-GISE) for comprehensive discussion and consensus development, with the aim of providing practical recommendations, for both clinical and interventional cardiologists, regarding optimal management of PFO in patients with cerebral or systemic thromboembolism. In this position paper, various clinical scenarios in patients with and without high-risk PFO features are presented and discussed, including PFO patients with associated conditions (e.g. hypercoagulable states, deep vein thrombosis/pulmonary embolism, short runs of atrial fibrillation), and special subsets (e.g. patients with risk factors for atrial fibrillation, patients aged ≥65 years, patients who refused percutaneous PFO closure), with the Panel's recommendations being provided for each scenario.

RESUMO

BACKGROUND: Evidence-based recommendations about anticoagulation in acute type B aortic dissection (TBAD) are completely missing, but there is a diffuse conviction that it could prevent the healing process of the dissected aorta's false lumen. However, several clinical conditions may lead to the necessity to start anticoagulant therapy among patients with acute type B aortic dissection, ranging from atrial fibrillation to more complicated clinical scenarios and the correct management in this kind of patients is still an open issue. CASE PRESENTATION: We are presenting a 51-years-old man with multi-infarct encephalopathy referred to us for an acute TBAD and a first diagnosis of ischemic cardiomyopathy complicated by left ventricular (LV) thrombus formation. Coronary angiography revealed a critical stenosis of left anterior descending artery (LAD) treated with drug-eluting stent deployment. The patient was addressed to triple antithrombotic therapy with acetylsalicylic acid, clopidogrel and warfarin with target INR 2.0-2.5. After 6 months, computed tomography angiography revealed the stability of the dissection flap. Cardiac magnetic resonance imaging, however, confirmed the persistence of a small thrombotic formation in LV apex, thus double antithrombotic therapy with warfarin and clopidogrel was instituted. The patient remained asymptomatic during the follow-up period but was advised to suspend his job and physical activities. CONCLUSION: Current guidelines do not discuss anticoagulant therapy in the setting of TBAD and large randomized trials are lacking. Despite it is generally considered unsafe to administer anticoagulants in patients with TBAD, we present a case in which triple antithrombotic therapy was well tolerated and did not lead to progression of the intimal flap after 6 months.

RESUMO

INTRODUCTION: Cardiovascular diseases are the leading cause of mortality worldwide. Apical periodontitis (AP) has been associated with an increased risk of cardiovascular diseases. A correlation has been shown between chronic AP and endothelial dysfunction (ED), but there is no evidence to indicate ED improves after endodontic treatment in patients with periapical lesions. The aim of this study was to investigate vascular and molecular markers of early ED before and after root canal treatment in young adults with chronic AP. METHODS: Twenty control subjects and 21 patients with AP were assessed at baseline. The AP patients were also evaluated 2 and 12 months post-treatment. Endothelial flow reserve was assessed via an endothelial function test, and enzyme-linked immunosorbent assays were used to evaluate plasma levels of proinflammatory cytokines interleukin (IL)-1, IL-6, and tumor necrosis factor alpha; vasoconstrictor ED marker endothelin (ET)-1; circulating endothelial adhesion markers intercellular adhesion molecule 1 (ICAM-1)/CD54 and soluble vascular cellular adhesion molecule (sVCAM)-1/CD106; soluble CD14; and the endothelial leukocyte adhesion molecule (E-selectin). RESULTS: AP was associated with increased serum levels of ET-1, ICAM-1, E-selectin, IL-1, and sCD14, suggesting early vascular ED, with no macroscopic evidence of a reduction in endothelial flow reserve. Root canal treatment ameliorated inflammation and early ED, lowering plasma levels of IL-1, sCD14, ET-1, ICAM-1/CD54, and E-selectin to those of control subjects. CONCLUSIONS: Our findings suggest that AP may drive early vascular ED and that the endodontic therapy of AP ameliorates early ED.

RESUMO

AIM: An underlying atrial vulnerability or a preexisting misdiagnosed atrial fibrillation in some patients who are candidates for patent foramen ovale (PFO) closure may lead to an unnecessary percutaneous intervention. The aim of this work was to define paroxysmal atrial fibrillation rate, through a 6-month insertable loop-recorder monitoring, in patients over 55 years old with cryptogenic stroke and PFO. METHODS: PFO closure criteria: significant right-to-left shunt and at least one high-risk feature (permanent right-to-left shunt, atrial septal aneurysm, prominent Eustachian valve, recurrent brain ischemia, previous deep vein thrombosis, thrombophilia). Insertable cardiac monitoring criteria: previous cryptogenic stroke, more than 55 years and at least one atrial fibrillation risk factor (heart failure, hypertension, age older than 65 years, diabetes, atrial runs, left atrium dilatation, left ventricle hypertrophy, pulmonary disease, thyroid disease, obesity). Atrial fibrillation detection threshold: arrhythmia duration longer than 5 min. RESULTS: From January 2008 to March 2017, 195 patients underwent to loop-recorder monitoring. A total of 70 (36%) patients were candidates for PFO closure. The 6-month silent atrial fibrillation rate was 11.4%. In the arrhythmia-free cohort, 28 patients (45.2%) underwent percutaneous foramen ovale closure (group A) and 34 (54.8%) were medically treated (group B). Atrial fibrillation detection rate was 14.3% in group A and 0% in group B. The 36-month atrial fibrillation-free survival was 76%. CONCLUSION: An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

RESUMO

The presence of a patent foramen ovale (PFO) is implicated in the pathogenesis of a number of medical conditions; however, the subject remains controversial and no official statements have been published. This interdisciplinary paper, prepared with involvement of eight European scientific societies, aims to review the available trial evidence and to define the principles needed to guide decision making in patients with PFO. In order to guarantee a strict process, position statements were developed with the use of a modified grading of recommendations assessment, development, and evaluation (GRADE) methodology. A critical qualitative and quantitative evaluation of diagnostic and therapeutic procedures was performed, including assessment of the risk/benefit ratio. The level of evidence and the strength of the position statements of particular management options were weighed and graded according to predefined scales. Despite being based often on limited and non-randomised data, while waiting for more conclusive evidence, it was possible to conclude on a number of position statements regarding a rational general approach to PFO management and to specific considerations regarding left circulation thromboembolism. For some therapeutic aspects, it was possible to express stricter position statements based on randomised trials. This position paper provides the first largely shared, interdisciplinary approach for a rational PFO management based on the best available evidence.

RESUMO

BACKGROUND: Cell therapy with bone marrow (BM)-derived progenitors has emerged as a promising therapeutic for refractory angina (RA) patients. In the present study, we evaluated the safety and preliminary efficacy of transcatheter delivery of autologous BM-derived advanced therapy medicinal product CD133+ cells (ATMP-CD133) in RA patients, correlating perfusion outcome with cell function. METHODS: In the phase I "Endocavitary Injection of Bone Marrow Derived CD133+ Cells in Ischemic Refractory Cardiomyopathy" (RECARDIO) trial, a total of 10 patients with left ventricular (LV) dysfunction (ejection fraction ≤ 45%) and evidence of reversible ischemia, as assessed by single-photon emission computed tomography (SPECT), underwent BM aspiration and fluoroscopy-based percutaneous endomyocardial delivery of ATMP-CD133. Patients were evaluated at 6 and 12 months for safety and preliminary efficacy endpoints. ATMP-CD133 samples were used for in vitro correlations. RESULTS: Patients were treated safely with a mean number of 6.57 ± 3.45 ×  106 ATMP-CD133. At 6-month follow-up, myocardial perfusion at SPECT was significantly ameliorated in terms of changes in summed stress (from 18.2 ± 8.6 to 13.8 ± 7.8, p = 0.05) and difference scores (from 12.0 ± 5.3 to 6.1 ± 4.0, p = 0.02) and number of segments with inducible ischemia (from 7.3 ± 2.2 to 4.0 ± 2.7, p = 0.003). Similarly, Canadian Cardiovascular Society and New York Heart Association classes significantly improved at follow-up vs baseline (p ≤ 0.001 and p = 0.007, respectively). Changes in summed stress score changes positively correlated with ATMP-CD133 release of proangiogenic cytokines HGF and PDGF-bb (r = 0.80, p = 0.009 and r = 0.77, p = 0.01, respectively) and negatively with the proinflammatory cytokines RANTES (r = - 0.79, p = 0.01) and IL-6 (r = - 0.76, p = 0.02). CONCLUSION: Results of the RECARDIO trial suggested safety and efficacy in terms of clinical and perfusion outcomes in patients with RA and LV dysfunction. The observed link between myocardial perfusion improvements and ATMP-CD133 secretome may represent a proof of concept for further mechanistic investigations.

RESUMO

OBJECTIVES: To investigate the long-term clinical outcomes of second-generation drug-eluting stent (2G-DES) implantation for the treatment of complex unprotected left main coronary artery (ULMCA) bifurcation lesions with different two-stent techniques. BACKGROUND: Several two-stent techniques for ULMCA bifurcation lesions have been described. However, a paucity of data exists regarding the optimal strategy, especially in the 2G-DES era. METHODS: The FAILS-2 registry enrolled 1270 consecutive patients treated for ULMCA stenosis with 2G-DES. We compared long-term outcomes of different two-stent strategies in patients who underwent PCI for complex ULMCA bifurcation disease. The primary endpoints were the incidence of death and major adverse cardiac events (MACE, defined as a composite of all-cause death, myocardial infarction [MI], target-lesion revascularization [TLR], and stent thrombosis [ST]) at long-term follow-up. RESULTS: A total of 238 patients were included in the present analysis. T-stenting strategy was used in 66 patients, mini-crush in 104 patients, and culotte in 68 patients. After a median follow-up of 2.27 years, death rates were comparable for the three techniques (9.3% T-stenting vs 9.0% mini-crush vs 4.5% culotte [P=.48]). MACE rates were also similar between the three groups (22% T-stenting vs 26% mini-crush vs 31% culotte [P=.50]). Finally, we showed no differences in MI, ST, and TLR rates between groups. At multivariate analysis, no significant advantage of one technique over the others was observed. CONCLUSION: T-stenting, mini-crush, and culotte techniques using 2G-DES for ULMCA bifurcation disease showed similar clinical outcomes at long-term follow-up. MACE rates were mainly driven by in-stent restenosis at the circumflex ostium.

RESUMO

AIMS: The impact of the severity of coronary artery disease (CAD) and percutaneous coronary interventions (PCI) on outcomes after transcatheter aortic valve implantation (TAVI) remains a matter of debate. We therefore performed a meta-analysis to evaluate the impact of CAD, of its severity and of PCI on mortality after TAVI. METHODS AND RESULTS: All published studies evaluating the impact of CAD on 30-day and one-year mortality after TAVI at multivariable analysis were included. The primary endpoint was the impact of CAD severity (assessed with the SYNTAX score [SS]) on one-year mortality by pooling with logarithmic transformation results of multivariable adjusted effect estimates from each individual study. Secondary endpoints were the impact of the presence of CAD on 30-day and one-year mortality at multivariable analysis and the impact of residual SYNTAX score (rSS) on one-year mortality at multivariable analysis. A total of 8,334 patients with a median age of 81.3 (81-82) years and STS score of 6.2% (IQR 6.0-6.7) from 13 studies were included. Patients with an SS >22 showed higher one-year mortality at multivariable analysis (OR 1.71 [1.24-2.36]). The presence of CAD did not impact on 30-day and one-year mortality at multivariable analysis (respectively, OR 1.57 [0.71-3.46] and OR 1.25 [0.74-2.11]). Regarding PCI, patients with rSS <8 showed lower one-year mortality (OR 0.34 [0.012-0.93]). CONCLUSIONS: The risk of death after TAVI is closely related to the complexity of CAD. Patients with an SS >22 present higher mortality. SS may represent a useful tool to select patients undergoing TAVI who could benefit from coronary revascularisation. In this regard, reaching an rSS <8 reduced one-year mortality. Randomised controlled trials are needed to confirm these results.

RESUMO

INTRODUCTION: Different devices have been released for closure of femoral vascular access after coronary angiography or percutaneous coronary intervention, whereas evidence about their efficacy and safety when compared with manual compression or head to head is lacking, especially across different diameters of sheaths, age and sex. RESULTS: A total of 30 studies were included in the analysis. Manual compression was evaluated as the control group in all of the included studies (5620 patients), Angioseal in 15 studies (17-29) (1812 patients), Exoseal in two studies (30-31) (1773 patients), Perclose in six (29, 32-37) (849 patients), Vasoseal in eight (36, 38-43) (699 patients), DUETT in one study (44) (392 patients), StarClose in two studies (23, 45) (334 patients), Techstar in two studies (37, 46) (252 patients) and extravascular staple in one study (47) (242 patients). At network meta-analysis, all the devices resulted as not superior to manual compression to reduce all vascular complications, and these results did not vary at metaregression for age, sex and diameter of sheaths. Manual compression significantly increased time to hemostasis when compared with Femoseal (5.72; 1.91-19.10), Vasoseal (5.11; 2.32-11.33), Perclose (3.46; 1.70-7.06), Angioseal (14.95; 7.84-28.57) and Techstar (9.78; 1.81-53.65), while was similar to StarClose, DUETT and Exoseal. CONCLUSION: Different vascular devices for closure of femoral access did not results superior to manual compression to reduce complications, whereas offered a shorted time to hemostasis. StarClose was the device with the highest probability to perform best in terms of complication, whereas Angioseal was superior in terms of reduction of time to hemostasis.
