Abstract
Abstract
Background
Migraine is a chronic neurovascular disorder with a multifactorial aetiology. A strong relationship links migraine with aura (MHA) and patent foramen ovale (PFO), with migraine regression after PFO closure. Increased platelet aggregation and oxidative stress were documented in migraineurs. Current guidelines suggest the use of aspirin or P2Y12-antagonists. To date, however, no clear mechanisms connecting MHA to PFO has been demonstrated.
Purpose
To perform a comprehensive analysis of platelet activation, inflammation and oxidative stress status in 78 aspirin-treated MHA-patients before (T0) and 6-months after (T1) PFO closure (LEARNER Study-NCT03521193-clinicaltrials.gov). Primary endpoint was migraine regression rate in relation to these parameters.
Methods
P-selectinpos-, activated-glycoproteinIIbIIIa (aGPIIbIIIa)pos-, Tissue Factor (TF)pos-, reactive oxygen species (ROS)pos-platelets, platelet-leukocyte aggregates (PLA) and microvesicles (MVs) were evaluated by flow cytometry; thrombin generation (TG) by Calibrated Automated Thrombogram (CAT) assay; oxidative stress status by mass spectrometry. Twelve aspirin-treated-healthy subjects (HS) were enrolled for comparison. To test the effect of PFO patients' plasma on platelet activation, blood from HS was plasma-depleted and replaced with a pool of plasma from PFO patients.
Results
Migraine resolution occurred in 69.7%, significant reduction in 27%, while no effect was observed in 2 patients (3.2%). Only ROSpos-platelets, and TFpos-platelets and -MVs were significantly higher at T0, sustaining a TG capacity that was associated with an altered blood GSSG/GSH (Oxidized/Reduced Glutathione) ratio. This phenotype reverted to HS levels at T1 (Fig. 1). MHA-PFO plasma, added to HS blood, mirrored the in vivo platelet activation and N-acetylcysteine blunted it. In vitro GSSG treatment of HS platelets reproduced the in vivo condition. Aspirin had little effect on the platelet prothrombotic phenotype which was effectively inhibited by a P2Y12-antagonist (Fig.2).
Conclusions
MHA-PFO patients show a platelet-associated prothrombotic phenotype, characterized by a marked thrombin generation capacity sustained by an elevated number of platelets and MVs expressing a functionally active Tissue Factor and sustained by altered oxidative stress status. This phenotype, not fully controlled by aspirin but by P2Y12-antagonism, reverted after PFO closure together with a complete migraine remission.

Abstract
Abstract
Introduction
Preliminary reports from the early phase of COVID-19 epidemic in Italy reported a dramatic reduction in hospital admission rates for acute coronary syndromes (ACS) coupled with longer times from symptoms onset to hospital presentation.
Purpose
To assess the impact of COVID-19 on hospital admission rates and ACS patterns, as well as time to presentation and clinical outcomes, following the acute pandemic phase in 2020 compared to previous year.
Methods
We conducted a single institution retrospective analysis conducted in a cardiovascular hub serving a large metropolitan area in Italy. Number and monthly distribution of hospital admissions for ACS from January 1 to December 31, 2020 were compared to the respective figures in 2019. Baseline clinical features, time from symptoms onset to hospital admission and main clinical outcomes were collected.
Results
A total of 599 ACS cases were recorded in 2020 vs. 386 cases in 2019, with a net 55% increase. ACS presentation rate in 2020 showed a bimodal pattern, paralleling the most contagious outbreak periods (Figure 1). SARS-CoB-2 nasopharyngeal swab or specific antibody tests were positive in 34 (5.7%) patients. Time from symptoms onset to hospital presentation tended to be longer in 2020 than in 2019, being two-fold longer during the peak epidemic phase (February 21-May 3, 2020; median time 2.0 vs. 5.0 hours, p=0.030). The proportion of late-presenting STEMI (>8 hrs from symptoms onset) was higher in 2020 compared to 2019 (30% vs. 18%, p=0.003),as well as higher was in-hospital mortality (15% in 2020 vs 6% in 2019, p=0.001), partly due to a three-fold increase in cardiogenic shock on ACS presentation.
Conclusions
ACS admission rate significantly increased during the 2020 COVID-19 epidemic outbreak for several reasons only partially explained by a SARS-CoV-2 infection trigger effect on ACS. Longer presentation times and higher rates of cardiogenic shock and mortality were observed, urging the need health-care systems to keep a high priority on cardiovascular emergencies response networks.

Abstract
Abstract
Background
Although the long-term outcome of mechanical mitral and aortic prosthetic valve (M-PV, Ao-PV), PV dysfunction (PVD) remains a very serious complication associated with high morbidity and mortality. PVD, in terms of thrombosis/pannus or paravalvular leak, is not associated with a peculiar clinical presentation. However, a prompt PVD detection is essential for referring the patient to the optimal treatment (clinical follow-up, thrombolysis, surgery). An integrated multimodality imaging approach, comprising several parameters by transthoracic echocardiography (TTE) and fluoroscopy (F), is mandatory to address the patient to the best therapeutic option.
Purpose
This study aims to evaluate the incremental diagnostic value of combined TTE + F over each imaging modality alone in pts with Ao-PV or M-PV symptomatic for dyspnea, embolic events, fever or haemolysis and therefore at high suspicion for PVD.
Methods
We enrolled 388 consecutive pts (62 ± 11y, 213 Ao-PV, 175 M-PV) suspected for PVD. All patients were imaged by TTE and F within 2 days after the admission to the hospital. TTE was defined positive for PVD in presence of intra/para-prosthetic regurgitation or high transprosthetic gradient (DP > 20 mmHg in Ao-PV, DP >10 mmHg in M-PV) combined with other altered Doppler parameters (for Ao-PV: DVI < 0.25, AT > 95ms; for M-PV: Peak Mitral Velocity > 2.2m/sec, VTIPrMV/VTILVO > 2.5, PHT > 130ms). A positive F for PVD was defined by leaflet/s restriction. In all pts, PVD was confirmed by transoesophageal echocardiography (TOE), positive response of thrombolysis (T), or surgical inspection (S).
Results
PVD was found in 46% (99/213) of Ao-PV and in 56% (98/175) of M-PV at TOE/T/S. Sensitivity (SE), specificity (SP), negative predictive value (NPV), positive predictive value (PPV) and diagnostic accuracy (ACC) for TTE, F and combined TTE + F are reported in Table. The integration of TTE + F data significantly improved ACC both for Ao-PV and M-PV. At ROC analysis, the combined model of TTE + F showed the highest AUC for the detection of PVD compared with TTE and F alone (Figure).
Conclusions
In patients with clinical suspicion of PVD, the combined model of TTE + F had a significant incremental value over TTE or F alone to diagnose PVD. This multimodality imaging approach allows to overcome limitations of TTE or F alone and consequently provides a prompt PVD detection even though TOE remains the gold standard to diagnose paravalvular leak and non-obstructive thrombosis.

Abstract
Background
Although the long-term outcome of mechanical mitral and aortic prosthetic valve (M-PV, Ao-PV), PV dysfunction (PVD) remains a very serious complication associated with high morbidity and mortality. Thrombosis/pannus and paravalvular leak are the 2 main mechanisms of PVD. The diagnosis of PVD, based on clinical presentation may be challenging, but it is essential for referring the patient to the optimal treatment (clinical follow-up, thrombolysis, surgery). An integrated multimodality imaging approach, comprising several parameters by transthoracic echocardiography (TTE) and fluoroscopy (F), is mandatory to pursue the correct therapeutic pathway.
Purpose
This study aims to evaluate the incremental diagnostic value of combined TTE+F over each imaging modality alone in symptomatic pts with Ao-PV or M-PV and high suspicion of PVD.
Methods
387 consecutive pts (63±11y, 213 Ao-PV, 173 M-PV) suspected for PVD, symptomatic for dyspnea, embolic events, fever or haemolysis were enrolled. All patients were imaged by TTE and F within 2 days after the admission to the hospital. TTE was defined positive for PVD in presence of intra/para-prosthetic regurgitation or high transprosthetic gradient (>20mmHg in Ao-PV, >8mmHg in M-PV) together with altered Doppler parameters (for Ao-PV: DVI <0.25, AT>95ms; for M-PV: Peak Mitral Velocity>2m/sec, VTIPrMV/VTILVO>2.5, PHT>130ms). F was defined positive for PVD when leaflet/s restriction occurs. PVD was confirmed by transoesophageal echocardiography (TOE) or positive response of thrombolysis (T), or surgical inspection (S).
Results
PVD was found in 46% (99/213) of Ao-PV and in 53% (91/173) of M-PV at TOE/T/S. Sensitivity (SE), specificity (SP), negative predictive value (NPV), positive predictive value (PPV) and diagnostic accuracy (ACC) for TTE, F and combined TTE+F are reported in Table. The integration of TTE+F data significantly improved ACC both for Ao-PV and M-PV. At ROC analysis, the combined model of TTE+F showed the highest AUC for the detection of PVD compared with TTE and F alone (Figure).

Conclusions
In patients with clinical suspicion of PVD, TTE and F are both valid tools to evaluate the PV performance. However, the combined model of TTE+F had a significant incremental value over TTE or F alone to diagnose the presence of PVD. This multimodality imaging approach allows to overcome several weaknesses of the TTE or F alone and consequently provides a prompt recognition of PVD even though TOE remains the gold standard to diagnose paravalvular Leak and non-obstructive thrombosis.

Abstract
We describe a new diagnostic catheter specifically designed for selective catheterization of the left internal mammary artery via the ipsilateral radial approach. We used this catheter to assess the patency of the distal mammary-left anterior descending coronary artery anastomosis in 30 consecutive patients early after minimally invasive direct coronary artery bypass grafting. The new catheter design allowed easy and fast engagement of the left internal mammary artery leading to optimal vessel opacification in all cases. Angiography revealed graft problems in seven (23.3%) patients, two of whom required anastomosis revision, surgical in one case and with PTCA in the other. No LIMA injury occurred as a result of selective catheterization. Patients with functionally normal anastomosis were discharged on the same day of the diagnostic procedure.
