CB-PVI for paroxysmal AF shows a 12-month success rate of 76.5% after one single procedure, as assessed by continuous cardiac rhythm monitoring. Within-blanking recurrences predict the ablation failure in more than 80% of patients.

Background Currently, the use of advanced ventricular support systems during percutaneous mitral valve repair (PMVR) procedures is confined to very few selected cases in emergency or bailout situations. No cases are reported of planned use of ventricular support devices in the subgroup of high-risk patients undergoing PMVR. Case summary We report two cases of planned and ‘protected’ procedures of PMVR with Impella CP mechanical circulatory support. No procedure-related complications occurred. At 6-month clinical follow-up evaluation, an improvement of symptoms and functional class (New York Heart Association) was reported. Discussion In the two cases reported, PMVR with Impella CP assistance was feasible, safe and effective in the setting of severe mitral regurgitation associated with dilated and severe left ventricular dysfunction. Extending the concept of ‘complex high-risk and indicated patients/procedures’ (CHIP) from the environment of coronary intervention, a ‘protected’ approach could lead to improve technical feasibility and clinical outcome in structural interventions, as advocated for ‘protected-percutaneous coronary intervention’.

Background. This study is aimed at comparing the clinical outcomes of unprotected left main coronary artery disease (ULMCAD) treatment with contemporary percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in a “real-world” population. Methods and Results. Overall, 558 consecutive patients with ULMCAD (mean age 71 ± 9 years, male gender 81%) undergoing PCI or CABG were compared. The primary endpoint was the composite of death, nonfatal myocardial infarction, or stroke. Diabetes was present in 29% and acute coronary syndrome in 56%; mean EuroSCORE was 11 ± 8. High coronary complexity (SYNTAX score >32) was present in 50% of patients. The primary composite endpoint was similar after PCI and CABG up to 4 years (15.5 ± 3.1% vs. 17.1 ± 2.6%; p = 0.585 ). The primary end point was also comparable in a two propensity score matched cohorts. Ischemia-driven revascularization was more frequently needed in PCI than in CABG (5.5% vs. 1.5%; p = 0.010 ). By multivariate analysis, diabetes mellitus (HR 2.00; p = 0.003 ) and EuroSCORE (HR 3.71; p < 0.001 ) were the only independent predictors associated with long-term outcome. Conclusions. In a “real-world” population with ULMCAD, a contemporary revascularization strategy by PCI or CABG showed similar long-term clinical outcome regardless of the coronary complexity.

The characteristics and clinical course of hospitalized patients with coronavirus disease 2019 (COVID-19) have been widely described, while long-term data are still poor. The aim of this study was to evaluate the long-term clinical outcome and its association with right ventricular (RV) dysfunction in hospitalized patients with COVID-19. This was a prospective multicenter study of consecutive COVID-19 patients hospitalized at seven Italian Hospitals from 28 February to 20 April 2020. The study population was divided into two groups according to echocardiographic evidence of RV dysfunction. The primary study outcome was 1-year mortality. The propensity score matching was performed to balance for potential baseline confounders. The study population consisted of 224 patients (mean age 69 ± 14, male sex 62%); RV dysfunction was diagnosed in 63 cases (28%). Patients with RV dysfunction were older (75 vs. 67 years, p < 0.001), had higher prevenance of coronary artery disease (27% vs. 11%, p = 0.003), and lower left ventricular ejection fraction (50% vs. 55%, p < 0.001). The rate of 1-year mortality (67% vs. 28%; p ≤ 0.001) was significantly higher in patients with RV dysfunction compared with patients without. After propensity score matching, patients with RV dysfunction showed a worse long-term survival (62% vs. 29%, p < 0.001). The multivariable Cox regression model showed an independent association of RV dysfunction with 1-year mortality. RV dysfunction is a relatively common finding in hospitalized COVID-19 patients, and it is independently associated with an increased risk of 1-year mortality.

Background Percutaneous coronary intervention (PCI) of unprotected left main coronary artery disease is currently recommended as an alternative to coronary artery bypass grafting (CABG) in patients with low and intermediate SYNTAX score. Purpose We sought to compare clinical outcomes of unprotected left main coronary artery disease by PCI or CABG in a “real world” population referred to high volume center. Methods All consecutive patients with unprotected left main coronary artery disease treated by PCI with second-generation drug-eluting stent were compared to those treated by CABG. The primary endpoint was the composite of death, non-fatal myocardial infarction (MI) or stroke at 2 years follow-up. Results A total of 558 patients were included. The mean age was 71±9 years, diabetes was present in 29%, and 56% of the patients presented with acute coronary syndrome. The distal left main coronary artery was involved in 84.6% of the lesions, the rate of Syntax score >32 was 50%. At 2 years, the primary end-point occurred in 10% of the patients in the PCI group and in 9.6% in the CABG group (p=0.862). The rates of death, non-fatal MI or stroke at 2 years were comparable; conversely the rate of ischemia driven revascularization at 2 years was higher in PCI group than CABG (5.5% and 1.5% p=0.010, respectively in PCI and CABG group). Kaplan-Meier curves of MACCE Conclusions In a “real world” population with unprotected left main coronary artery disease, PCI with second generation stent, as compared to CABG, showed similar rates of the composite end point of death, non-fatal MI or stroke at 2 years, irrespective of coronary anatomy complexity.

Aims The characteristics and clinical course of hospitalized patients with Coronavirus disease 2019 (COVID-19) have been widely described, while long-term data are still poor. The aim of this study was to evaluate the long-term clinical outcome and its association with right ventricular (RV) dysfunction in hospitalized patients with COVID-19. Methods and results This was a retrospective multicentre study of consecutive COVID-19 patients hospitalized at seven Italian Hospitals from 28 February to 20 April 2020. The study population was divided into two groups according to echocardiographic evidence of RV dysfunction defined by tricuspid annular plane systolic excursion (TAPSE) value &lt;17 mm in accordance with the current guidelines. The primary study outcome was 1-year mortality. The study population consisted of 224 patients (mean age 69 ± 14, male sex 62%); RV dysfunction was diagnosed in 63 cases (28%). Patients with RV dysfunction were older (75 vs. 67 years, P &lt; 0.001) and showed a higher prevalence of coronary artery disease (27% vs. 11%, P = 0.003), heart failure (5% vs. 22%; P &lt; 0.001), chronic obstructive pulmonary disease (13% vs. 38%; P &lt; 0.001), and chronic kidney disease (12% vs. 39%; P &lt; 0.001). Left ventricular ejection fraction (LVEF) was significantly lower in patients with RV dysfunction that in those without (55% vs. 50%; P &lt; 0.001). The rate of mortality at 1-year was significantly higher in patients with RV dysfunction as compared with those without (67% vs. 28%; P ≤ 0.001). After propensity score matching, patients with RV dysfunction showed a significantly lower long-term survival than patients without RV dysfunction (62% vs. 29%, P &lt; 0.001). At multivariable Cox regression analysis, TAPSE, LVEF and acute respiratory distress syndrome during the hospitalization were independently associated with 1-year mortality (Table). Conclusions RV dysfunction is a relatively common finding in hospitalized patients with COVID-19 and is independently associated with an higher risk of mortality at one-year follow-up.

Treatment of coronary chronic total occlusion (CTO) with percutaneous coronary intervention (PCI) has rapidly increased during the past decades. Different strategies and approach were developed in the recent past years leading to an increase in CTO-PCI procedural success. The goal to achieve an extended revascularization with a high rate of completeness is now supported by strong scientific evidences and consequently, has led to an exponential increase in the number of CTO-PCI procedures, even if are still underutilized. It has been widely demonstrated that complete coronary revascularization, achieved by either coronary artery bypass graft or PCI, is associated with prognostic improvement, in terms of increased survival and reduction of major adverse cardiovascular events. The application of “contemporary” strategies aimed to obtain a state-of-the-art revascularization by PCI allows to achieve long-term clinical benefit, even in high-risk patients or complex coronary anatomy with CTO. The increasing success of CTO-PCI, allowing a complete or reasonable incomplete coronary revascularization, is enabling to overcome the last great challenge of interventional cardiology, adding a “complex” piece to “complete” the puzzle.
