RESUMO
BACKGROUND: Crystalloid cardioplegic solutions are believed to reduce hemoglobin significantly and increase the transfusion rate. However, recent reports indicate that the del Nido cardioplegia may preserve blood morphology parameters. METHODS: In "The del Nido versus cold blood cardioplegia in aortic valve Replacement" trial patients undergoing aortic valve replacement were randomized into the del Nido (DN) or cold blood cardioplegia (CB) group. For the subanalysis, patients who underwent blood transfusions were excluded from the study. Red blood cell (RBC) count, hemoglobin, white blood cell (WBC) count and platelet (PLT) count were measured before the surgery, 24-, 48-, and 96 hours postoperatively. Furthermore, percental variation in first-last measure was compared in groups. In addition, indexed normalized ratio (INR) and activated partial thromboplastin time (aPTT) were compared preoperatively and 24 hours after the surgery. RESULTS: Eighteen (24%) patients from the del Nido group and 22 (29.3%) patients from the CB group received blood product transfusions (p = 0.560) and were excluded from further analysis. As such, 57 patients remained in DN group and 53 patients remained in CB group. No difference was found in RBC, hemoglobin, WBC, and platelet count in time intervals. Percental variation in first-last measure revealed higher fall in RBC (p = 0.0024) and hemoglobin (p = 0.0028) in the CB group. No difference was shown in preoperative and 24-hour postoperative INR and aPTT. CONCLUSIONS: The del Nido cardioplegia does not decrease blood morphology parameters when compared to cold blood cardioplegia and may be used alternatively regardless of bleeding and coagulopathy risk.

Percutaneous transaxillary approach (PTAX) through the first segment of the axillary artery is not widely recognized as a safe method. Furthermore, PTAX has never been directly compared between Impella-supported percutaneous coronary interventions (Impella-PCI) and transcatheter aortic valve replacement (TAVR). This study evaluated the feasibility and safety of PTAX through the first axillary segment in Impella-PCI versus TAVR. In cases where standard imaging guidance was insufficient, a technique involving puncturing the axillary artery "on-the-balloon" was employed. The endpoints were bleeding and vascular complications, as defined by BARC and VARC-3 criteria. PTAX was successfully performed in all 46 attempted cases: 23 for Impella-PCI and 23 for TAVR. Strict adherence to BARC and VARC-3 criteria led to the frequent identification of major bleeding (57%) and a moderately frequent diagnosis of vascular complications (17%). These incidences were primarily based on post-procedural hemoglobin reduction (> 3 g/dl) but not overt bleeding. The Impella group exhibited a higher rate of BARC 3b bleeding due to a greater hemoglobin decline resulting from the prolonged implant duration and PCI itself. Left axillary access was linked to smaller blood loss. Bleeding and vascular complications, as per BARC and VARC-3 definitions, did not affect short-term prognosis, with only 3 Impella patients succumbing to heart failure unrelated to the procedures during one-month follow-up period.

BACKGROUND: The objective of this multicenter study aimed to investigate the impact of sex on long-term survival among patients with multivessel coronary artery disease undergoing coronary artery bypass grafting (CABG) using multiple arterial grafting (MAG) or a single artery with saphenous vein grafts. MATERIALS AND METHODS: Data were obtained from the Polish National Registry of Cardiac Surgery Procedures database. This study included 81 136 patients who underwent CABG for multivessel disease between January 2012 and December 2020 (22.9 were women and 77.1% were men). MAG was performed in 8.3 and 11.7% of female and male patients, respectively. A 1:1 propensity score (PS)-matching was performed. Long-term mortality was compared between matched groups of men and women. Subgroup analyses of patients aged <70 and ≥70 years, with an ejection fraction (EF) >40% and ≤40%, and with and without diabetes, obesity, peripheral artery disease (PAD), or chronic lung disease (CLD) were performed separately in women and men. RESULTS: MAG was associated with lower long-term mortality than saphenous vein grafts in 1528 PS-matched female pairs [hazard ratio (HR): 0.74; 95% CI: 0.59-0.92; P =0.007) and 7283 PS-matched male pairs (HR: 0.80; 95% CI: 0.72-0.88; P <0.001). Subgroup analyses confirmed the results among female patients aged <70 years, with diabetes and EF >40%, and without PAD or CLD, and of male patients aged <70 and ≥70 years; with EF >40%; with or without diabetes, obesity, or PAD; and without CLD. CONCLUSIONS: In patients undergoing CABG, MAG was associated with significantly improved survival in both sexes. The long-term benefits of MAG observed across subgroups of men and women support the consideration of a multiarterial revascularization strategy for a broader spectrum of patients.

BACKGROUND: Neoplasmatic disease increases the risk of acute pulmonary embolism (APE) by different pathophysiological mechanisms that favor thrombosis in patients with cancer. Recently, the role of cancer (active and occult) in the prevalence of venous thromboembolism has been discussed more thoroughly in the subject literature. MATERIAL: Medical records of 366 consecutive patients with a diagnosis of APE (aged: meanâ=â65.0â±â16.6, medianâ=â68, rangeâ=â19-94; menâ=â41%/womenâ=â59%) were collected with a wide range of demographic data, medical history of coexisting diseases, computer examination, and laboratory tests. METHODS: The APE patients were analyzed in two groups: negative cancer cases (83%), i.e. without concomitant active malignancy or a history of cancer, and positive ones (17%), i.e. those hospitalized with concomitant active cancer disease or a history of cancer within the past 5 years. RESULTS: Based on the application of the Student's t -test for independent samples and the χ2 test of independence, a statistically significant difference ( P â<â0.05) between cancer (-) and cancer(+) groups of patients was calculated for the following selected risk factors: BMI, smoking status, hemoglobin, hematocrit, red blood cell, urea, glomerular filtration rate, high-sensitivity troponin T, C-reactive protein (CRP), D-dimer, and NT-proBNP. Using univariate Cox regression and a discrete-time hazard model, the estimated hazard ratios and odds ratios, respectively, for the risk of an earlier death from cancer as well as for a secondary APE episode in APE patients with malignancy are more than three times higher than in cancer-free patients and they are statistically significant ( P â<â0.05). Moreover, the modeled discrete-time hazard curves show a constant excess risk of death and a secondary APE episode in patients diagnosed with malignancy over the period of observation. CONCLUSION: Cancer and APE seem to go 'hand in hand'. Attention should be paid to many factors, primarily clinical, differentiating patients with cancer from those with an APE incident. The patients with cancer after a primary APE should receive anticoagulants to prevent a secondary APE episode and to reduce the risk of 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 optimal surgical strategy (repair vs replacement) for patients with secondary mitral (MV) regurgitation is questionable. METHODS: Patients who underwent MV repair or replacement for functional or ischemic mitral regurgitation between 2006 and 2017 were identified in Polish National Registry of Cardiac Surgery Procedures. Patients, who underwent additional procedures other than coronary artery bypass grafting or tricuspid valve surgery, as well as redo or emergency cases, were excluded. The long-term survival was verified based on National Health Fund registry. The survival was compared between MV repair and replacement both in the whole cohort and after propensity score matching. The Cox regression was used to seek for independent predictors of survival. RESULTS: Of 7633 identified patients, 1793 (23%) underwent MV replacement and 5840 (77%) underwent MV repair. Coronary artery bypass surgery was performed together with MV repair in 3992 (69%) patients and together with MV replacement in 915 (52%) patients (P < .001). Tricuspid valve surgery was added to 1393 (24%) MV repairs and to 561 (32%) MV replacements (P < .001). The crude actuarial 5-year survival was 71% (95% confidence interval [CI], 70%-72%) in the repair group and 66% (95% CI, 63%-68%) in the replacement group (P < .001). MV replacement was an independent predictor of mortality (hazard ratio, 1.32; 95% CI, 1.17-1.49) (P < .001) in Cox regression modeling. In the propensity-matched cohort (1105 pairs), the long-term mortality was also significantly higher in the replacement group (hazard ratio, 1.24; 95% CI, 1.06-1.45; P = .008). CONCLUSIONS: Repair of secondary mitral regurgitation has an associated survival benefit compared with MV replacement.

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
BACKGROUND: The evidence regarding the impact of patient's age and gender on del Nido cardioplegia cadio-protection capability in adults is strongly limited. METHODS: A group of 75 patients undergoing aortic valve replacement (AVR) with del Nido cardioplegia was divided into Group 1 (male) and Group 2 (female). Creatine kinase (CK-MB isoenzyme) and high sensitivity troponin T (hs-TnT) values at 24 hours and 48 hours, occurrence of cardiac activity during crossclamp and ventricular fibrillation (VF) during reperfusion were compared. The impact of age on hs-TnT,CK-MB, VF during reperfusion and cardiac activity during crossclamp was investigated using regression models. RESULTS: No difference between the groups was reported in 24-hour CK-MB (median 15.57 ng/mL; IQR 12.13-22.82 ng/mL vs. 13.97; 12.09-17.147 ng/mL; P=0.168), 48-hour CK-MB (6.19; 4.22-7.71 ng/mL vs. 6.07;4.56-7.06 ng/mL; P=0.707), 24-hour hs-TnT (259.2; 172.0-376.9 pg/mL vs. 193.0; 167.8-351 pg/mL.1; P=0.339), 48-hour hs-TnT (169.1; 124.9-293.0 pg/mL vs. 159.2; 123.12-211.77 pg/mL; P=0.673), VF during reperfusion (25% vs. 18,5%; P=0.774) and cardiac activity during arrest (39.6% vs. 37.1%; p= 1.0). Values of CK-MB at 24 hours, hs-TnT at 24 hours and hs-TnT at 48 hours were not dependent on age. The CK-MB at 48 hours was dependent on age (P=0.039). Probit regression failed to reveal the impact of patients' age on postclamp VF occurrence (P=0.11) or electrical activity during arrest (P=0.57). CONCLUSIONS: Considering our study results, it can be hypothesized that the del Nido cardioplegia provides adequate myocardial protection in AVR patients regardless of age and gender.

Percutaneous coronary intervention (PCI) of bifurcation lesions is a technical challenge associated with high risk of adverse events, especially in primary PCI. The aim of the study is to analyze long-term outcomes after PCI for coronary bifurcation in acute myocardial infarction (AMI). The outcome was defined as the rate of major adverse cardiac event related to target lesion failure (MACE-TLF) (death-TLF, nonfatal myocardial infarction-TLF and target lesion revascularization (TLR)) and the rate of stent thrombosis (ST). From 306 patients enrolled to the registry, 113 were diagnosed with AMI. In the long term, AMI was not a risk factor for MACE-TLF. The risk of MACE-TLF was dependent on the culprit lesion, especially in the right coronary artery (RCA) and side branch (SB) with a diameter >3 mm. When PCI was performed in the SB, the inflation pressure in SB remained the single risk factor of poor prognosis. The rate of cumulative ST driven by late ST in AMI was dependent on the inflation pressure in the main branch (MB). In conclusion, PCI of bifurcation culprit lesions should be performed carefully in case of RCA and large SB diameter and attention should be paid to high inflation pressure in the SB. On the contrary, the lower the inflation pressure in the MB, the higher the risk of ST.
RESUMO
BACKGROUND: To perform a retrospective analysis of patients who underwent endoscopic atraumatic coronary artery off-pump bypass grafting (EACAB) in a single center over a period of 11 years. METHODS: Data was acquired from the hospital registry and patient medical records. In order to determine changes in clinical profile, patients were subdivided into three groups regarding year of surgery: 1998-2002 (group 1), 2003-2005 (group 2), 2006-2009 (group 3). In-hospital analysis up to 30 days and long-term observation were conducted. RESULTS: The study cohort consisted of 714 patients (581 male). Procedural success accounted for 99% of all patients. No mortality was observed up to 30 days. Complications in the early period included pleural effusion (7.6%), cardiac arrhythmias (3.6%), bleeding related revision (2.7%) and wound infection (1.6%). Mean follow-up was 6 years (2132 ± 1313 days; median: 1918.5). Nineteen (2.7%) patients died, of which 52.6% (10 patients) were due to heart related conditions. Overall frequency of major adverse cerebral and cardiovascular events (MACCE) was 10.8% (77 patients). The Kaplan-Meyer analysis defined survival rate and event-free survival in long-term observation of 96.1% and 85.3%, respectively. Ejection fraction (EF) < 50% was the only independent factor of mortality (OR: 3.35). Regarding cumulative MACCE, older age (OR: 1.72), lower EF (OR: 3.03), the history of percutaneous coronary intervention (OR: 2.13) and higher New York Heart Association class (OR: 2.63) influenced the incidence rate. CONCLUSIONS: The presented short and very long-term results confirm that EACAB is an efficient alternative for patients requiring revascularization of the left anterior descending artery. The elimination of cardiopulmonary bypass significantly reduces the number of complications.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is being increasingly used in patients with longer life expectancy. Data on longterm outcomes are still limited. AIMS: The aim of the study was to assess the clinical outcomes of patients treated with TAVI and identify baseline and procedurerelated factors influencing longterm survival. METHODS: Symptomatic patients with critical aortic stenosis who were inoperable or had high surgical risk were qualified for TAVI. Between August 2012 and December 2017, 248 consecutive patients treated with self expanding Medtronic valve implantation at American Heart of Poland in BielskoBiala were prospectively enrolled. Patients were followed for 30 days after the procedure and subsequently annually. All events were classified according to the Valve Academic Research Consortium2 (VARC2) criteria and assessed. Survival was compared between the subgroups defined by the EuroSCORE II (European System for Cardiac Operative Risk Evaluation II) and with matched representatives from the general population. RESULTS: The median (interquartile range) followup was 3.4 (2.5-4.6) years, and the longest followup lasted 7.8 years. A total of 92 patients (37.1%) died during the followup. The Kaplan-Meier estimates for cumulative mortality at 1, 3, 5, and 7 years were: 11.3%, 26.8%, 42.1%, and 60.6%. Patients with EuroSCORE II greater than 6% experienced worse survival compared with those with EuroSCORE II 6% or less (P = 0.008). Patients with EuroSCORE II 6% or less had similar survival to the general population. Male sex, baseline eGFR of less than 50 ml/min/1.73 m2, chronic obstructive pulmonary disease, moderate / severe paravalvular leak, absence of postdilatation, major vascular complication, and stroke at 30 days were independently associated with longterm mortality. CONCLUSIONS: TAVI with a selfexpanding Medtronic valve implantation according to a consistent protocol was associated with favorable outcomes. Patients with lower EuroSCORE II scores had the same prognosis as the actuarial survival of the general population.

OBJECTIVES: To compare the cardioprotective efficacy of a solution that requires only a single infusion at the start of the ischemic duration versus a solution that requires multiple infusions. METHODS: Aortic valve replacement was performed for 150 patients, who were randomized into the del Nido (DN) cardioplegia group or the cold blood (CB) cardioplegia group. The DN cardioplegia was delivered every 90 minutes and the CB cardioplegia was delivered every 20 to 30 minutes, or whenever cardiac activity was observed. The primary endpoints were electrical cardiac activity during crossclamp, ventricular fibrillation during reperfusion, and postoperative troponin and creatine kinase (CK-MB isoenzyme) at 24 and 48 hours. RESULTS: Electrical activity during crossclamp occurred in 29 (39.7%) patients in the DN group versus 34 (45.3%) patients in the CB group (adjusted P = 1.0). The number of procedures with ventricular fibrillation after removing the crossclamp was 41 (54.7%) in the CB group versus 17 (22.7%) in the DN group (adjusted P = .001; relative risk, 2.41). Troponin values appeared to be lower in the DN group (median, 223.10; interquartile range, 168.35-364.77 pg/mL vs 285.5; 196.20-419.45 pg/mL at 24 hours and 159.60; 125.42-217.20 pg/mL vs 201.60; 160.62-268.45 pg/mL at 48 hours) and CK-MB (median, 14.94; interquartile range, 12.16-20.39 ng/mL vs 17.43; 13.66-22.43 ng/mL at 24 hours and 6.19; 4.41-7.63 ng/mL vs 7.38; 4.74-10.20 ng/mL at 48 hours), but no significance was found. CONCLUSIONS: The del Nido cardioplegia protocol is an acceptable alternative for cold blood cardioplegia in patients undergoing aortic valve replacement.

BACKGROUND: Asymptomatic patients with newly diagnosed severe primary mitral regurgitation (MR) may not be candidates for surgery according to clinical guidelines. AIMS: We aimed to determine whether asymptomatic patients with severe primary MR benefit from minimally invasive mitral valve repair. METHODS: This prospective registry study assessed consecutive asymptomatic patients who underwent mitral valve repair using right minithoracotomy. Left ventricular ejection fraction, enddiastolic and endsystolic volumes, enddiastolic and endsystolic diameters, as well as left atrial (LA) area and volume were measured. Major adverse cardiovascular and cerebrovascular events (MACCEs) were assessed at 6, 12, and 24 months after surgery. RESULTS: The study included 114 patients, of whom 16 (14%) were lost to followup (except the endpoint of death). No deaths were reported during followup. A comparison of median echocardiographic parameters at baseline and 24 months revealed significant reverse remodeling: left ventricular ejection fraction, 68% vs 60% (P <0.001); enddiastolic volume, 165 cm3 vs 107.5 cm3 (P <0.001); endsystolic volume, 51 cm3 vs 43.5 cm3 (P = 0.02), enddiastolic diameter, 58 mm vs 49 mm (P <0.001); endsystolic diameter, 35 mm vs 30 mm (P <0.001); LA area, 26 cm2 vs 18 cm2 (P <0.001); and LA volume, 96 cm3 vs 49.5 cm3(P <0.001). There were 9 MACCEs (9.2%): 2 reoperations (2%), 1 hospitalization for heart failure (1%), and 6 cases of newonset atrial fibrillation (6.1%). CONCLUSIONS: Minimally invasive mitral valve repair is safe and effective in asymptomatic patients with severe primary MR. It should be recommended regardless of ventricular and atrial dimensions.

BACKGROUND: Periprocedural antithrombotic prophylaxis in patients undergoing surgical valve procedures (SVP) is insufficiently investigated. Low molecular weight heparin (LMWH) has been considered as an alternative to unfractionated heparin (UFH). However, safety and efficacy of this prophylaxis strategy is unknown. This study aimed to investigate safety and efficacy of periprocedural LMWH prophylaxis and determine optimal dosage and timing for periprocedural cessation and initiation. METHODS: The present study is a retrospective, single-center observational analysis of 388 patients who underwent SVP (valve replacement or valvuloplasty) between 2015 and 2016. In-hospital endpoints were bleeding, transfusions, reoperation due to bleeding, and thromboembolic events. RESULTS: Giving the first dose of LMWH on the day of SVP was a risk factor for bleeding (OR 1.07; 95% CI 1.04-1.10; p < 0.001), transfusions (OR 1.04; 95% CI 1.01-1.07; p = 0.008) and reoperation due to bleeding (OR 1.20; 95% CI 1.12-1.28; p < 0.001), with > 40 mg/day as a predictor. A higher dosage of LMWH premedication was an independent risk factor for bleeding (OR 1.02; 95% CI 1.00-1.04; p = 0.03) and transfusion (OR 1.03; 95% CI 1.01-1.05; p = 0.01), with > 60 mg/day as a predictor for these events. LMWH dosed within 24 h prior to SVP increased the risk of transfusion (AUC 0.636; 95% CI 0.496-0.762; p = 0.04). CONCLUSIONS: Bleeding is an important early concern after surgical valve procedures. Safety and efficacy of periprocedural prophylaxis with LMWH depends on dosage and the timing of its administration. The most optimal periprocedural prophylaxis in the SVP population appears to be LMWH in dosage of 40-60 mg/day, which is recommended for deep vein thrombosis prophylaxis, ceased at least one day before SVP.

BACKGROUND: Air pollution triggered diseases have become a leading health problem worldwide. The main adverse effects of air pollutants on human health are related to the cardiovascular system and particularly show an increasing prevalence of myocardial infarct and stroke. The aim of the study was to evaluate the influence of main air pollutants on non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI) admissions to local interventional cardiology centers. METHODS: Between 2014 and 2015, a multicenter registry of 1957 patients with acute myocardial infarction (STEMI, NSTEMI) admitted to interventional cardiology departments in three Polish cities were under investigation. The air pollution (PM2.5, PM10, NO2, SO2, O3) and weather conditions (temperature, barometric pressure, humidity) data for each city were collected as daily averages. The case-crossover design and conditional logistic regression were used to explore the association between acute myocardial infarctions and short-term air pollution exposure. RESULTS: Occurrence of NSTEMI on the day of air pollution was triggered by PM2.5 (OR = 1.099, p = 0.01) and PM10 (OR = 1.078, p = 0.03). On the following day after the air pollution was recorded, NSTEMI was induced by: PM2.5 (OR = 1.093, p = 0.025), PM10 (OR = 1.077, p = 0.025) and SO2 (OR = 1.522, p = 0.009). For STEMI, events that occurred on the day in which air pollution was triggered by: PM2.5 (OR = 1.197, p < 0.001), PM10 (OR = 1.163, p < 0.001), SO2 (OR = 1.670, p = 0.001) and NO2 (OR = 1.287, p = 0.011). On the following day after air pollution was recorded, STEMI was induced by: PM2.5 (OR = 1.172, p < 0.001), PM10 (OR = 1.131, p = 0.001), SO2 (OR = 1.550, p = 0.005) and NO2 (OR = 1.265, p = 0.02). None of the weather conditions indicated were statistically significant for acute myocardial infarction occurrence. CONCLUSIONS: The most important pollutants triggering acute myocardial infarction occurrence in the population of southern Poland, both on the day of air pollution and the following day are particulate matters (PM2.5, PM10) and gaseous pollutants including NO2 and SO2. These pollutants should be regarded as modifiable risk factors and thus, their reduction is a priority in order to decrease total morbidity and mortality in Poland.

BACKGROUND: According to the medical literature, both on-pump and off-pump coronary artery surgery is safe and effective in octogenarians. OBJECTIVES: The aim of our study was to examine the epidemiology, in-hospital outcomes and long-term follow-up results in octogenarians undergoing off-pump and on-pump coronary artery surgery utilizing nationwide registry data. METHODS: All octogenarians (≥ 80 years) enrolled in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry), who underwent isolated coronary surgery between January 2006 and September 2017 were identified. Preoperative data, perioperative complications, hospital mortality and long-term mortality were analyzed. Unadjusted and propensity-matched comparisons were performed between octogenarians undergoing off-pump and on-pump coronary artery bypass surgery. RESULTS: Octogenarians accounted for 4.1% of the total population undergoing coronary artery surgery in Poland during the analyzed period (n = 152,631) and this percentage is increasing. Among 6,006 analyzed patients, 2,744 (45.7%) were operated on-pump and 3,262 (54.3%) were operated off-pump. Propensity-matched analysis revealed that patients operated on-pump were more often reoperated due to postoperative bleeding and their in-hospital mortality was higher (6.6% vs 4.5%, p = 0.006 and 8.7% vs 5.8%, p = 0.001, respectively). Long-term all-cause mortality was lower among patients operated off-pump (p = 0.013). CONCLUSION: On the basis of our findings we suggest that off pump technique should be considered as perfectly acceptable in octogenarians.

BACKGROUND: The impact of coronary artery bypass grafting (CABG) on the quality of life (QoL) is one of the important measures of the efficacy of the procedure. This issue in young, professionally active male patients has not been extensively studied. AIM: To assess QoL before and after on-pump CABG, and before and after cardiac rehabilitation in young men with low operative risk. METHODS: The study group comprised 50 men aged 54.4 +/- 5.6 years who were professionally active before the surgery. The QoL was assessed on the basis of the MacNew questionnaire (in points). We analysed QoL changes and effects of basic demographic and peri-operative data on QoL during a short-term follow-up. RESULTS: All components of QoL deteriorated shortly after CABG: emotional - from 4.97 +/- 0.96 to 4.66 +/- 1.0 (p = 0.03); physical - from 4.49 +/- 1.1 to 4.2 +/- 1.2 (p = 0.02); and social - from 4.68 +/- 1.0 to 4.47 +/- 1.1 (p = 0.1). Pre-operative physical and social QoL positively correlated with age (r = 0.45 and r = 0.37, respectively) and left ventricular ejection fraction (LVEF) (r = 0.49 and r = 0.48, respectively). However, there was a negative impact of history of myocardial infarction on physical QoL (p < 0.05). A negative influence of cardiopulmonary bypass time (r = -0.45) and cross-aortic clamp time (r = -0.36) on physical QoL was also noted. The QoL values were also influenced by class of angina symptoms (R = -0.33 / -0.42), total drainage (r = -0.11 / -0.34) and quantity of grafts (R = -0.35 / -0.42). During rehabilitation, QoL significantly improved: emotional - from 5.29 +/- 0.92 to 5.96 +/- 0.9 (p = 0.01); physical - from 4.66 +/- 1.1 to 5.42 +/- 1.2 (p < 0.01); and social - from 4.69 +/- 1.2 to 5.65 +/- 1.1 (p < 0.01). The QoL during rehabilitation was correlated with baseline peri-operative risk (for logistic EuroSCORE algorithm r = -0.21 / -0.31 and for EuroSCORE R = -0.47 / -0.89). Significant determinants of some components of QoL were also LVEF (r= 0.26 / 0.47), morphological blood parameters (r = 0.37 / 0.43), baseline CCS class (R = 0.31 / 0.58), age (r = -0.41 / -0.83), and extent of surgery defined by cardiopulmonary bypass time, cross-aortic clamp duration and total drainage. CONCLUSIONS: Quality of life in young, professionally active men significantly deteriorates a few days after on-pump CABG but systematically improves during the next weeks, particularly after rehabilitation. Pre-operative QoL correlates positively with age and LVEF, and negatively with a history of myocardial infarction. Age, pre-operative risk, angina symptoms and the extent of surgery have negative effects on physical QoL after CABG during short-term observation.

Patients with severe symptomatic aortic stenosis, who from November 2008 to March 2009 were treated with Edwards-Sapien transcatheter aortic valve implantation (TAVI) within the POL-TAVI First Polish Registry, were included in the analysis. Nineteen patients aged 78+/-4.8 years with high operation risk and Logistic EuroSCORE 25+/-7.6% were reported (74% were females). In 15 (79%) patients the valve was implanted transapically (TA), in the other four (21%)--via the femoral arterial access (TF). The valve was successfully implanted in 16 (84%) patients, in one patient aortic valvuloplasty alone was performed. During in-hospital period two patients died (one during periprocedural period and another one--two months after the implantation). During the mean follow-up of 5+/-1.5 months (except for one patient who is still in hospital) all patients are in NYHA class I or II. Results of the initial series of 19 TAVI patients in Poland are satisfactory, and the trial will be continued with careful medical and economical analysis.

INTRODUCTION: Minimally invasive mitral repair is less traumatic and more acceptable for the patient than traditional surgery. However, it is a challenging procedure that requires effort from all the personnel involved. AIM: To investigate the results of the minimally invasive mitral valve repair learning curve at the institution. MATERIAL AND METHODS: The indication for the surgery was severe mitral regurgitation. Patients with other valvular insufficiency, body mass index (BMI) > 30 kg/m2, ejection fraction (EF) < 45%, aortic dilatation, reoperation, pleural adhesions, coronary artery disease requiring invasive treatment, and pregnant women were disqualified. The patients were assigned to one of three groups regarding their surgery date - group 1 (2012-2013), group 2 (2014-2015) and group 3 (2016-2017). The primary endpoints were death, myocardial infarction, stroke, an reoperation for mitral dysfunction. The investigation was performed to determine preoperative parameters (EuroSCORE, age, sex, BMI, arrhythmias, EF), intraoperative parameters (procedure, cross-clamp, extracorporeal circulation), and postoperative parameters (chest revision, transfusion, drainage, ventilation time, pleurocentesis, hospitalization time). RESULTS: There were 173 patients in total. One patient from group 1 (0.6% overall) died. No myocardial infarction or stroke was observed in any of the three groups. Chest revision count (5 vs. 1 vs. 1; p = 0.0004), total drainage (797.20 vs. 517.92 vs. 449.69; p = 0.0018) and hospitalization time (7.89 vs. 7.18 vs. 6.73; p = 0.0005) were significantly different among the groups. The ventilation time, transfusion number and pleurocentesis count did not differ significantly. CONCLUSIONS: The procedure is safe and ensures optimal perioperative results. The number of complications is low and acceptable.
RESUMO
INTRODUCTION: Off-pump coronary artery bypass grafting is considered potentially more effective than on-pump surgery in elderly patients. AIM: To compare the early and long-term results of these techniques in patients ≥ 80 years of age with left main coronary artery disease. MATERIAL AND METHODS: All patients ≥ 80 years of age (N = 3648) who were reported to the Polish National Registry of Cardiac Surgery Procedures between 2006 and 2016 and underwent primary, isolated coronary artery bypass surgery were included in the study. The patients were divided into 2 groups: group A - without significant left main stenosis (LMS) (n = 2094) and B group - with LMS ≥ 50% (n = 1524). The groups were compared according to the type of surgery: on-pump (A = 1107 vs. B = 891), off-pump (A = 908 vs. B = 616) and MIDCAB (A = 79 vs. B = 17). RESULTS: There were significant differences in preoperative status between the groups in the whole cohort, which were not observable after propensity score matching. The in-hospital mortality was significantly higher in the LMS group operated on-pump (10.5% vs. 7.0%; p = 0.01) and non-significant in the off-pump group (5.1% vs. 5.7%; p = 0.78), as well as in the MIDCAB subgroup (5.9% vs. 5.1%; p = 0.64). 10-year survival in all subgroups was comparable and remained at a level of 50-60%. The mean entire cohort follow-up was 3.4 ±2.7 vs. 3.7 ±2.8 years (p = 0.2). CONCLUSIONS: Off-pump coronary bypass grafting may optimize the outcomes in elderly patients with significant left main stenosis. Octogenarians surgically treated for coronary artery disease, despite increased post-operative risks, present encouraging long-term survival.
