RESUMO
BACKGROUND: An investigation of baseline characteristics, treatment, and outcomes in patients with stable coronary disease after the first wave of the severe acute respiratory syndrome coronavirus 2 (SARS- -CoV-2) pandemic may provide valuable data and is beneficial for public health strategy in upcoming years. METHODS: A multi-institutional registry, including 10 cardiology departments, was searched for patients admitted from June 2020 to October 2020. The baseline characteristics (age, gender, symptoms, comorbidities), treatment (non-invasive, invasive, surgical), and hospitalization outcome (mortality, myocardial infarction, stroke, composite endpoint - major adverse cardiac and cerebrovascular events [MACCE]) were evaluated. The comparison was made to parameters presented by patients from the same timeframe in 2019 (June-October). Multivariable analysis was performed. RESULTS: Number of hospitalized stable patients following lockdown was lower (2498 vs. 1903; p < 0.0001). They were younger (68.0 vs. 69.0; p < 0.019), more likely to present with hypertension (88.5% vs. 77.5%; p < 0.0001), diabetes (35.7% vs. 31.5%; p = 0.003), hyperlipidemia (67.9% vs. 55.4%; p < 0.0001), obesity (35.8% vs. 31.3%; p = 0.002), and more pronounced symptoms (Canadian Cardiovascular Society [CCS] III and CCS class IV angina: 30.4% vs. 26.5%; p = 0.005). They underwent percutaneous treatment more often (35.0% vs. 25.9%; p < 0.0001) and were less likely to be referred for surgery (3.7% vs. 4.9%; p = 0.0001). There were no significant differences in hospitalization outcome. New York Heart Association (NYHA) class IV for heart failure was a risk factor for both mortality and MACCE in multivariate analysis. CONCLUSIONS: The SARS-CoV-2 2019 pandemic affected the characteristics and hospitalization course of stable angina patients hospitalized following the first wave. The hospitalization outcome was similar in the analyzed time intervals. The higher prevalence of comorbidities raises concern regarding upcoming years.

BACKGROUND: The collateral damage caused by the COVID-19 pandemic affected cardiovascular disease patients, mainly acute coronary syndrome (ACS) cases. Additionally, lockdown caused treatment-related concerns and reluctance to seek medical help, factors that can delay treatment. AIM: We aimed to analyze the incidence and course of ACS after the first COVID-19 wave. METHODS: The report is based on a multi-institutional registry of 10 interventional cardiology departments. ACS patient data were gathered from June to October 2020, i.e. in the period following the first lockdown in Poland (March 30-May 31, 2020) and compared with the corresponding 2019 timeframe. RESULTS: Patients (2801 and 2620) hospitalized for ACS in 2019 and 2020 (June-October) represented 52.8% and 57.9% of coronary artery disease admissions, respectively. In 2020 vs. 2019, more cases of arterial hypertension (80.2% vs. 71.5%; P <0.001), diabetes (32.7% vs. 28.2%; P <0.001) hyperlipidemia (53.2% vs. 49.8%; P = 0.01), and smoking history (29.5% vs. 25.8%; P = 0.003) were detected. Median troponin and cholesterol values, as well as glycemia, were higher in 2020. Patients were more likely to undergo percutaneous treatment (91.2% vs. 87.5%; P <0.001) and were less often referred for surgery (3.7% vs. 4.9%; P = 0.03). No differences in deaths from repeat myocardial infarction, stroke, and/or composite endpoint (major adverse cardiac and cerebrovascular events [MACCE]) were noted. However, suffering from ACS in 2020 (June-October) was a risk factor for mortality based on multivariable analysis. CONCLUSIONS: The COVID-19 pandemic affected ACS patient profile, course of treatment, and increased risk for mortality.

BACKGROUND: The evidence on performing minimally invasive coronary artery surgery early after drug-eluting stent (DES) implantation due to acute coronary syndrome (ACS) is limited. AIM: The study aimed to determine the safety and feasibility of this approach. METHODS: This registry included 115 (78% male) patients treated from 2013 to 2018, who underwent non-left anterior descending (LAD) percutaneous coronary intervention (PCI) due to ACS with contemporary DES implantation (39% diagnosed with myocardial infarction at baseline), followed by endoscopic atraumatic coronary artery bypass (EACAB) surgery within 180 days, after temporary P2Y12 inhibitor discontinuation. Primary composite endpoint of MACCE (major adverse cardiac and cerebrovascular events), defined as death, myocardial infarction (MI), cerebrovascular incident, and repeat revascularization was evaluated in long-term follow-up. The follow-up was collected via a telephone survey and in line with National Registry for Cardiac Surgery Procedures. RESULTS: The median (interquartile range [IQR]) time interval separating both procedures was 100.0 (62.0-136.0) days. Median (IQR) follow-up duration was 1338.5 (753.0-2093.0) days and was completed for all patients with regard to mortality. Eight patients (7%) died; 2 (1.7%) had a stroke; 6 (5.2%) suffered from MI, and 12 (10.4%) required repeat revascularization. Overall, the incidence of MACCE was 20 (17.4%). CONCLUSIONS: EACAB is a safe and feasible method of LAD revascularization in patients who received DES for ACS within 180 days before surgery despite early dual antiplatelet therapy discontinuation. The adverse event rate is low and acceptable.

BACKGROUND: The Coordinated Care in Myocardial Infarction Program (KOS-MI) was introduced to improve prognosis for patients after myocardial infarction (MI). The program includes complete revascularization followed by unrestricted access to rehabilitation, electrotherapy and cardiac care. AIM: The aim of this study was to assess major adverse cardiac and cerebrovascular events (MACCE) of patients enrolled in the KOS-MI at 3-year follow-up. METHODS: This is a retrospective, multicenter registry of patients treated for MI. Study group (KOS-MI) of 963 patients was compared to the control group (standard of care) of 1009 patients. At 3-year follow-up MACCE including death, MI, stroke and repeated revascularization were reported. Additionally, hospitalization due to heart failure (HF) was analyzed. Propensity score matching (PSM) was utilized for group baseline characteristics adjustment. RESULTS: Patients in the KOS-MI group were younger (65 vs. 68; P < 0.001), mostly men (70% vs. 62.9%; P < 0.001), admitted with ST-elevation myocardial infarction (STEMI) (44.6% vs. 36.2%; P < 0.001). Patients in the control group had more comorbidities and were admitted more often with non ST-elevation myocardial infarction (63.8% vs. 55.4%; P < 0.001) and acute HF (5.1% vs. 2.7%; P = 0.007). Following PSM 530 well matched pairs were selected. At three years (92.3% follow-up completeness), the relative risk reduction was: 25% in MACCE (P = 0.008), 38% in mortality (P = 0.008), 29% in repeated revascularization(P = 0.04) and 28% (P = 0.0496) in hospitalization for HF in the KOS-MI group. CONCLUSIONS: The combination of contemporary invasive techniques, complete revascularization, cardiac rehabilitation and ambulatory care included in the KOS-MI Program improves long-term prognosis of patients after MI up to 3-year follow-up.
RESUMO
Objectives: The aim of the study is to evaluate the functionality, durability, and temporal biocompatibility of a novel, balloon-expandable polymeric transcatheter heart valve (ATHV) system (InFlow, CardValve Consortium, Poland). Along with expanding TAVI indications, the demand for new transcatheter valves is increasing. Methods: A surgical ascending aortic banding model was created in 20 sheep. Two weeks later, 16 sheep were implanted with ATHV systems (15-16F). Three animals were euthanized after a 30-day follow-up, four animals after a 90-day follow-up, and six animals after a 180-day follow-up. A follow-up transthoracic echocardiography (TTE) was performed. Results: There was one procedure-related (6,25%) and two model-related deaths (12,5%; banding site calcification with subsequent infection originating externally from banding). TTE revealed the flow gradients (max/average) of 30,75/17,91; 32,57/19,21; and 21,34/10,63 mmHg at 30, 90, and 180 days, respectively. There were two cases of low-degree regurgitation after 180 days with no perivalvular leak observed. Histopathological analysis showed no valve degeneration at terminal follow-up with optimal healing. Small thrombi were present at the aortic wall adjacent to the base of the leaflets, and between the aortic wall and the stent in most of the valves; however, leaflets remained free from thrombi in all cases. Scanty calcifications of leaflets were reported in three animals evaluated 180 days after implantation. Conclusion: This preclinical study in the aortic banding model showed good hemodynamic performance, durability, and biocompatibility of the novel ATHV. Furthermore, regulatory studies with longer follow-ups are warranted.
RESUMO
Background: The constant growth of interest in hybrid coronary artery revascularization (HCR) is apparent. Yet, few studies report outcomes of the one-stage HCR. Consequently, the status of such procedures is not adequately supported in clinical guidelines. The aim of this study was to report the safety, feasibility, and long term-outcomes of the one-stage HCR. Methods and results: Patients were enrolled in the prospective one-stage hybrid coronary revascularization program (HYBRID-COR). They underwent a one-stage hybrid revascularization procedure while on double antiplatelet therapy (DAPT) with Ticagrelor: endoscopic atraumatic coronary artery bypass grafting (EACAB) for revascularization of the left anterior descending (LAD) artery and percutaneous intervention in non-LAD arteries with contemporary drug-eluting stents. The composite primary endpoint included MACCE (major adverse cardiac and cerebrovascular events: death, myocardial infarction, stroke, and repeated revascularization) in long-term observation. The study cohort consisted of 30 patients (68% male) with stable coronary artery disease (26.7%) and unstable angina (73.3%). Procedural success was 100%. No death, myocardial infarction (MI), or stroke were observed in the perioperative period. One patient (3.3%) required chest revision and blood transfusion due to surgical bleeding. Kidney injury was noted in two patients (6.6%). In a long-term follow-up (median; IQR: 4.25; 2.62-4.69 years), two patients (6.6%) underwent repeated revascularization and one patient (3.3%) died due to MI. The overall primary endpoint rate was 9.9%. Conclusion: One-stage hybrid revascularization, on DAPT, is a feasible, safe, and efficient way of achieving complete revascularization in selected patients. The complication rate is low and acceptable. Further randomized trials are required.
RESUMO
The aim of the study was to evaluate a balloon expandable transcatheter heart valve (THV) system (Myval) at 6-month follow-up in ovine banding model. Eleven THV systems were implanted via carotid approach. There were 2 procedure-related deaths and 2 premature deaths. At 6 months all valves that completed follow-up (n = 7) were functional, with no significant regurgitation, calcification, thrombi, or vegetation. Mean pressure gradient was 21.9 ± 11 mm Hg, maximum velocity = 3.3 ± 1 m/s, and ejection fraction was 53.3 ± 6%. Myval THV showed optimal hemodynamic performance and biocompatibility.
