Thromboembolic Complications in Adult Patients Following Fontan Procedure-A Multicenter Study. J Clin Med 2023; 12:jcm12103465. [PMID: 37240571 DOI: 10.3390/jcm12103465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 04/20/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND Morbidity and mortality following Fontan (FO) surgery are primarily thromboembolic in nature. However, follow-up data regarding thromboembolic complications (TECs) in adult patients after FO procedure are inconsistent. In this multicenter study, we investigated the incidence of TECs in FO patients. METHODS We studied 91 patients who underwent FO procedure. Clinical data, laboratory, and imaging investigations were collected prospectively during the scheduled medical appointments in 3 Adult Congenital Heart Disease Departments in Poland. TECs were recorded during a median follow-up of 31 months. RESULTS Four patients (4.4%) were lost to follow-up. The mean age of patients was 25.3 (±6.0) years at enrollment, and the mean time between FO operation and investigation was 22.1 (±5.1) years. A total of 21 out of 91 patients (23.1%) had a history of 24 TECs since an FO procedure, mainly pulmonary embolism (PE; n = 12, 13.2%), including 4 (33.3%) silent PE. The mean time since FO operation to the first TEC was 17.8 (±5.1) years. During follow-up, we documented 9 TECs in 7 (8.0%) patients, mainly PE (n = 5, 5.5%). Most patients with TEC had a left type of systemic ventricle (57.1%). Three patients (42.9%) were treated with aspirin, 3 (3.4%) with Vitamin K antagonists or novel oral anticoagulants, and 1 patient had no antithrombotic treatment at the time of TEC occurrence. Supraventricular tachyarrhythmias were present in 3 patients (42.9%). CONCLUSIONS This prospective study shows that TECs are common in FO patients, and a significant number of these events occur during adolescence and young adulthood. We also indicated how much TECs are underestimated in the growing adult FO population. The complexity of the problem requires more studies, especially to standardize the prevention of TECs in the whole FO population.

Infective endocarditis in adults with congenital heart disease: Contemporary management and related outcomes in Central and South-Eastern European region. Int J Cardiol 2023; 377:45-50. [PMID: 36638916 DOI: 10.1016/j.ijcard.2023.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 12/28/2022] [Accepted: 01/09/2023] [Indexed: 01/12/2023]
Abstract
BACKGROUND Infective endocarditis (IE) remains major cause of morbidity and mortality in adult congenital heart disease (ACHD). Limited data exists on ACHD with IE in Central and South-Eastern European (CESEE) countries. The aim of this study is to characterize contemporary management and assess outcomes of ACHD with IE in CESEE region. METHODS Data on ACHD patients with IE from 9 tertiary centres in 9 different CESEE countries between 2015 and 2020 was included. Baseline demographics, clinical presentation, indication for surgery, outcomes, hospital and all-cause-1-year mortality were studied. RESULTS A total of 295 ACHD patients (mean age 40 ± 14 years) with IE were included. Median time from symptoms onset to establishing diagnosis was 25 (11-59) days. The majority of patients (203, 68.8%) received previous empiric oral antibiotic therapy. The highest incidence of IE was observed on native and left sided valves, 194(65.8%) and 204(69.2%), respectively. More than half had a vegetation size ≥10 mm (164, 55.6%); overall 138 (46.8%) had valve complications and 119 (40.3%) had heart failure. In-hospital mortality was 26 (8.8%). CONCLUSION There is clear delay in establishing IE diagnosis amongst ACHD patients in CESEE countries. Adequate diagnosis is hampered by common prescription of empiric antibiotics before establishing formal diagnosis. Hence, patients commonly present with associated complications requiring surgery. Hospital treatment and survival are, nevertheless, comparable to other Western European countries. Improved awareness and education of patients and medical profession regarding IE preventive measures, risks, signs, and symptoms are urgently needed. Empiric antibiotic prescription before blood cultures are taken must be omitted.

Abstract
BACKGROUND Patients after acute myocardial infarction (AMI) are at very high cardiovascular (CV) risk. Therefore, appropriate management of dyslipidemia with adequate lipid-lowering therapy is crucial for preventing subsequent CV events in these patients. AIMS Our analysis aimed to assess the treatment of dyslipidemia and the attainment of low-density lipoprotein (LDL) -cholesterol treatment goals in patients after AMI who participated in the Managed Care for Acute Myocardial Infarction Survivors (MACAMIS) program. METHODS This study is a retrospective analysis of consecutive patients with AMI who agreed to participate and completed the 12-month MACAMIS program at one of three tertiary referral cardiovascular centers in Poland between October 2017 and January 2021. RESULTS 1499 patients after AMI were enrolled in the study. High-intensity statin therapy was prescribed to 85.5% of analyzed patients at hospital discharge. Combined therapy with high-intensity statin and ezetimibe increased from 2.1% at hospital discharge to 18.2% after 12 months. In the whole study cohort, 20.4% of patients achieved the LDL-C target of CONCLUSIONS: Our analysis suggests that participation in the managed care program might be associated with improved quality of dyslipidemia management in AMI patients. Nonetheless, only one-fifth of patients who completed the program achieved the treatment goal for LDL-C. This highlights the constant need for optimizing lipid-lowering therapy to meet treatment targets and to reduce CV risk in patients after AMI.

Abstract
Women with single ventricle physiology after the Fontan procedure, despite numerous possible complications, can reach adulthood and give birth. Pregnancy poses a hemodynamic burden for distorted physiology of Fontan circulation, but according to the literature, it is usually well tolerated unless the patient is a "failing" Fontan. Our study aimed to assess maternal and fetal outcomes in patients after the Fontan procedure followed up in two tertiary Polish medical centers. We retrospectively evaluated all pregnancies in women after the Fontan procedure who were followed up between 1995-2022. During the study period, 15 women after the Fontan procedure had 26 pregnancies. Among 26 pregnancies, eleven ended with miscarriages, and 15 pregnancies resulted in 16 live births. Fetal complications were observed in 9 (56.3%) live births, with prematurity being the most common complication (n = 7, 43.8%). We recorded 3 (18.8%) neonatal deaths. Obstetrical complications were present in 6 (40%) out of 15 completed pregnancies-two (13.3%) cases of abruptio placentae, two (13.3%) pregnancies with premature rupture of membranes, and two (13.3%) patients with antepartum hemorrhage. There was neither maternal death nor heart failure decompensation during pregnancy. In two (13.3%) women, atrial arrhythmia developed. One (6.7%) patient in the second trimester developed ventricular arrhythmia. None of the patients suffered from systemic thromboembolism during pregnancy. Pregnancy in women after the Fontan procedure is well tolerated. However, it is burdened by a high risk of miscarriage and multiple obstetrical complications. These women require specialized care provided by both experienced cardiologists and obstetricians.

Dissimilarity in coagulation system in adults after Fontan surgery based on thrombin generations. EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY : OFFICIAL JOURNAL OF THE EUROPEAN ASSOCIATION FOR CARDIO-THORACIC SURGERY 2022; 63:6887143.

Abstract
OBJECTIVES The Fontan procedure is the treatment of choice in congenital cardiac malformations defined as the single ventricle. Fontan patients are at high risk of thromboembolism, but the exact mechanism of this is poorly understood. The aim of this study was to evaluate an involvement of thrombin generations and microparticles (MPs) in prothrombotic state in adults with Fontan circulation. METHODS This study included hospitalized patients after Fontan procedure and healthy volunteers. We assessed laboratory tests including thrombin generation by calibrated automated thrombography in three variants [platelet-poor plasma (impact of coagulation factors), platelet-rich plasma (PRP) (influence of platelets) and related with MPs]. The technique allows for a comprehensive evaluation of the coagulation system. RESULTS The study groups consisted of 81 adult Fontan patients [41 females (50.6%); median age 22 interquartile range [20-27] years] and 54 control subjects. In patients with Fontan circulation, higher values of endogenous thrombin potential and peak values were observed for both platelet-poor plasma (+17% and +33%) and MPs (+29% and 41%) compared to controls (all P < 0.05). Moreover, in the Fontan group, we found a 64.9% shorter lag time and a 70.4% time to peak for MP variant (both P < 0.001). Contrarily, analysis in the PRP showed 17.1% of reduced endogenous thrombin potential in Fontan. Furthermore, there were no differences in thrombin synthesis in PRP in Fontan patients receiving aspirin or those with thrombocytopaenia (all P > 0.05). CONCLUSIONS This study for the first time showed that thrombin generation associated with MPs may be an important contributor to the prothrombotic state in the Fontan population.

Abstract
Structural, hemodynamic, and morphological cardiac changes following Fontan operation (FO) can contribute to the development of arrhythmias and conduction disorders. Sinus node dysfunction, junction rhythms, tachyarrhythmias, and ventricular arrhythmias (VAs) are some of the commonly reported arrhythmias. Only a few studies have analyzed this condition in adults after FO. This study aimed to determine the type and prevalence of arrhythmias and conduction disorders among patients who underwent FO and were under the medical surveillance of the John Paul II Hospital in Krakow. Data for the study were obtained from 50 FO patients (mean age 24 ± 5.7 years; 28 men (56%)). The median follow-up time was 4 (2–9) years. Each patient received a physical examination, an echocardiographic assessment, and a 24 h electrocardiogram assessment. Bradyarrhythmia was diagnosed in 22 patients (44%), supraventricular tachyarrhythmias in 14 patients (28%), and VAs in 6 patients (12%). Six patients required pacemaker implantation, and three required radiofrequency catheter ablation (6%). Arrythmias is a widespread clinical problem in adults after FO. It can lead to serious haemodynamic impairment, and therefore requires early diagnosis and effective treatment with the use of modern approaches, including electrotherapy methods.

Abstract
Objectives: thromboembolic complications are a major cause of morbidity and mortality following Fontan (FO) surgery. It is also well established that altered FO circulation results in systemic complications, including liver and endothelium damage. We sought to evaluate whether dysfunctions of these sources of hemostatic factors may result in changes of fibrin clot properties. Methods: a permeation coefficient (Ks) and clot lysis time (CLT) were assessed in 66 FO patients, aged 23.0 years [IQR 19.3–27.0], and 59 controls, aged 24.0 years [IQR 19.0–29.0]. Ks was determined using a pressure-driven system. CLT value was measured according to assay described by Pieters et al. Endothelium and liver-derived hemostatic factors along with liver function parameters were evaluated. The median time between FO operation and investigation was 20.5 years [IQR 16.3–22.0]. Results: FO patients had lower Ks (p = 0.005) and prolonged CLT (p < 0.001) compared to that of controls. Ks correlated with CLT (r = −0.28), FVIII (r = −0.30), FIX (r = −0.38), fibrinogen (r = −0.41), ALT (r = −0.25), AST (r = −0.26), GGTP (r = −0.27) and vWF antigen (r = −0.30), (all p < 0.05). CLT correlated with the time between FO operation and investigation (r = 0.29) and FIX (r = 0.25), (all p < 0.05). After adjustment for potential cofounders, TAFI antigen and GGTP were independent predictors of reduced Ks (OR 1.041 per 1% increase, 95% CI 1.009–1.081, p = 0.011 and OR 1.025 per 1 U/L increase, 95% CI 1.005–1.053, p = 0.033, respectively). Protein C and LDL cholesterol predicted prolonged CLT (OR 1.078 per 1% increase, 95% CI 1.027–1.153, p = 0.001 and OR 6.360 per 1 μmol/L increase, 95% CI 1.492–39.894, p = 0.011, respectively). Whereas elevated tPA was associated with lower risk of prolonged CLT (OR 0.550 per 1 ng/mL, 95% CI 0.314–0.854, p = 0.004). GGTP correlated positively with time between FO surgery and investigation (r = 0.25, p = 0.045) and patients with abnormal elevated GGTP activity (n = 28, 42.4%) had decreased Ks, compared to that of the others (5.9 × 10−9 cm2 vs. 6.8 × 10−9 cm2, p = 0.042). Conclusion: our study shows that cellular liver damage and endothelial injury were associated with prothrombotic clot phenotype reflected by Ks and CLT.

Abstract
Reduction of heart rate variability (HRV) parameters may be a risk factor and precede the occurrence of arrhythmias or the development of heart failure and complications in people with postinfarct left ventricular dysfunction and after coronary artery bypass grafting. Data on this issue in adults after a Fontan operation (FO) are scarce. This study assessed the association between HRV, exercise capacity, and multiorgan complications in adults after FO. Data were obtained from 30 FO patients (mean age 24 ± 5.4 years) and 30 healthy controls matched for age and sex. HRV was investigated in all patients by clinical examination, laboratory tests, echocardiography, a cardiopulmonary exercise test, and 24-h electrocardiogram. The HRV parameters were reduced in the FO group. Reduced HRV parameters were associated with patients’ age at the time of FO, time since surgery, impaired exercise capacity, chronotropic incompetence parameters, and multiorgan complications. Univariate analysis showed that saturated O2 at rest, percentage difference between adjacent NN intervals of >50 ms duration, and peak heart rate were associated with chronotropic index. Multivariable analysis revealed that all three variables were independent predictors of the chronotropic index. The results of this study suggest novel pathophysiological mechanisms that link HRV, physical performance, and organ damage in patients after FO.

Abstract
The prothrombotic state in patients with atrial fibrillation (AF) is related to
endothelial injury, the activation of platelets and the coagulation cascade. We
evaluated the levels of platelet- (CD42b) and endothelial-derived (CD144)
microparticles in the plasma patients with non-valvular AF treated with
dabigatran at the time of expected minimum and maximum drug plasma
concentrations. Following that, we determined the peak dabigatran plasma
concentration (cpeak ). CD42b increased after taking dabigatran
(median [IQR] 36.7 [29.4-53.3] vs. 45.6 [32.3-59.5] cells/µL; p = 0.025). The
concentration of dabigatran correlated negatively with the post-dabigatran
change in CD42b (ΔCD42b, r = -0.47, p = 0.021). In the multivariate model, the
independent predictors of ΔCD42b were: cpeak (HR -0.55; with a 95%
confidence interval, CI [-0.93, -0.16]; p = 0.007), coronary artery disease
(CAD) (HR -0.41; 95% CI [-0.79, -0.02]; p = 0.037) and peripheral artery disease
(PAD) (HR 0.42; 95% CI [0.07, 0.74]; p = 0.019). CD144 did not increase after
dabigatran administration. These data suggest that low concentrations of
dabigatran may be associated with platelet activation. PAD and CAD have distinct
effects on CD42b levels during dabigatran treatment.

Abstract
It is known that atrial fibrillation (AF) is associated with the procoagulant
state. Several studies have reported an increase of circulating microparticles
in AF, which may be linked to a hypercoagulable state, atrial thrombosis and
thromboembolism. We evaluated in our study alterations in both platelet (PMP,
CD42b) and endothelial-derived (EMP, CD144) microparticle levels on
anticoagulant therapy with rivaroxaban in nonvalvular AF. After administration
of rivaroxaban, PMP levels were increased (median, [IQR] 35.7 [28.8-47.3] vs.
48.4 [30.9-82.8] cells/µL; P = 0.012), along with an increase
in EMP levels (14.6 [10.0-18.6] vs. 18.3 [12.9-37.1] cells/µL,
P < 0.001). In the multivariable regression analysis,
the independent predictor of post-dose change in PMPs was statin therapy (HR
−0.43; 95% CI −0.75,−0.10, P = 0.011). The post-dose change in
EMPs was also predicted by statin therapy (HR −0.34; 95% CI −0.69, −0.01,
P = 0.046). This study showed an increase in both EMPs and
PMPs at the peak plasma concentration of rivaroxaban. Statins have promising
potential in the prevention of rivaroxaban-related PMP and EMP release. The
pro-thrombotic role of PMPs and EMPs during rivaroxaban therapy requires further
study.

Abstract
BACKGROUND Although patients undergoing the Fontan procedure (FP) present a normal or close‑to‑‑normal function of the systemic ventricle, they cannot generate cardiac output or exhibit similar exercise capacity as their healthy peers. This can be attributed to chronotropic incompetence and multiple organ complications. AIMS We evaluated the prevalence of chronotropic incompetence in adults after FP and assessed the relationship between heart rate reserve (HRR) and multiple organ complications. METHODS Data were obtained from 50 post‑FP patients (mean [SD] age, 27 [6.6] years) and 30 healthy controls matched for age and sex. All patients were subjected to clinical examination, laboratory tests, echocardiography, cardiopulmonary exercise test, and chronotropic function evaluation. RESULTS Cardiopulmonary exercise test parameters were impaired in the post‑FP group. Chronotropic incompetence was identified in 46 patients (92%), who also had a lower median (interquartile range) chronotropic index (0.55 [0.47-0.62] vs 0.93 [0.88-0.99]; P <0.001) and a greater median (interquartile range) HRR (32 [24-60] bpm vs 8 [1-14] bpm, P <0.001). A negative correlation was observed between HRR and peak oxygen uptake, and a positive one between HRR and the peak ventilatory equivalent for CO2 and mean platelet volume. The study revealed the diagnostic utility of HRR in detecting an abnormal peak ventilatory equivalent for O2, alkaline phosphatase levels, the ratio of aspartate transaminase to alanine transaminase levels, and mean platelet volume. CONCLUSIONS Chronotropic incompetence correlates with impaired exercise capacity, liver dysfunction, and platelet abnormalities in post‑FP patients. Heart rate reserve may be a promising indicator of organ complications as well as a sign of future bradyarrhythmia and the need for cardiac pacing.

Abstract
Objectives: The coarctation of aorta is commonly related to bicuspid aortic valve. The aim of the study was to assess arterial stiffness in adults after aortic coarctation repair and to evaluate an impact of bicuspid aortic valve concomitance on arterial stiffness results.Methods: Fifty-eight patients after coarctation of aorta repair, 36 male, median age of 27.46 ± 10.57, were compared to 30 with bicuspid aortic valve and to 30 healthy, sex, age and BMI matched volunteers. Physical examination, laboratory analysis and non-invasive assessment of arterial stiffness were performed.Results: CoA patients and BAV patients have higher central arterial stiffness parameters in comparison to healthy controls: AP (7.86 ± 6.56 vs 7.68 ± 5.96 vs 1.41 ± 3.82 mmHg, p < 0.001, p = 0.011, respectively) and AIx (18.81 ± 14.94 vs 18.06 ± 13.38 vs 4.41 ± 10.82%, p < 0.001, p = 0.006, respectively). There were no differences of PWV between CoA patients, BAV patients and healthy controls (6.07 ± 1.20 vs 5.95 ± 1.20 vs 5.67 ± 0.73 m/s, p = 0.099, p = 0.278, respectively). In CoA group, there was correlation of PWV with age (r = 0.55 p < 0.001), BMI (r = 0.29, p = 0.025), fibrinogen (r = 0.31, p = 0.039), glucose (r = 0.58, p < 0.001), ascending aorta diameter (r = 0.29, p = 0.026) and age at operation (r = 0.27, p = 0.041). Among group of BAV, there was a correlation of PWV with age (r = 0.58, p < 0.001), central AP with total cholesterol (r = 0.38, p = 0.036) and fibrinogen (r = 0.41, p = 0.024).Conclusions: The increased arterial stiffness occurs in both groups: patients after aortic coarctation repair and patients with bicuspid aortic valve. Concomitance of coarctation of the aorta and bicuspid aortic valve has no influence on arterial stiffness augmentation.

Abstract
INTRODUCTION Rare cardiovascular diseases and disorders (RCDDs) constitute an important clinical problem, and their proper classification is crucial for expanding knowledge in the field of RCDDs. OBJECTIVES The aim of this paper is to provide an updated classification of rare arrhythmogenic and conduction disorders, and rare arrhythmias (RACDRAs). METHODS We performed a search for RACDRAs using the Orphanet inventory of rare diseases, which includes diseases with a prevalence of no more than 5 per 10 000 in the general population. We supplemented this with a search of PubMed and Scopus databases according to a wider definition proposed by the European Parliament and the Council of the European Union. RESULTS RACDRAs are categorized into 2 groups, primary electrical disorders of the heart and arrhythmias in specific clinical settings. The first group is further divided into subgroups of major clinical presentation: disorders predisposing to supraventricular tachyarrhythmias, ventricular tachyarrhythmias, bradyarrhythmias, and others. The second group includes iatrogenic arrhythmias or heart rhythm disturbances related to medical treatment, arrhythmias associated with metabolic disorders, and others. We provide a classification of RACDRAs and supplement them with respective RCDDs codes. CONCLUSION The clinical classification of RACDRAs may form a basis to facilitate research and progress in clinical practice, both in diagnostic and therapeutic approaches.

Abstract
UNLABELLED The bicuspid aortic valve (BAV) is a congenital heart disease. AIM The aim of study was to evaluate the assessment of atherosclerosis risk factors in adult patients with bicuspid aortic valve compared against 30 healthy, age and sex matched volunteers. MATERIALS AND METHODS Thirty patients (22 males, 8 females) at an average age of 27.00 ±10.6 years were compared against thirty healthy, age and sex matched volunteers. The arterial blood pressure, lipid profile, fasting glucose, inflammation markers and the lifestyle factors were analysed. RESULTS Patients with bicuspid aortic valve have a higher level of glucose (4.95 vs 4.7 mmol / l, p = 0.026) and fibrinogen (2.25 vs. 1.98 g / l, p = 0.001) compared to the control group. In the group of patients with bicuspid aortic valve there was no hypertension, diabetes, tachycardia, stress exposure, alcohol abuse and a positive family history of cardiovascular diseases. CONCLUSIONS The patients with bicuspid aortic valve have higher glucose and fibrinogen levels and they need systematic checking to reduce cardiovascular risk factors.

Abstract
INTRODUCTION A hemodynamic derangement in Fontan circulation causes liver pathology known as Fontan‑‑associated liver disease. Although liver biopsy is a standard for diagnosis of liver fibrosis, noninvasive methods are being developed, including shear wave elastography (SWE). OBJECTIVES We aimed to evaluate the degree of liver stiffness (LS) using SWE in patients with Fontan circulation in a long‑‑term follow‑‑up and to investigate a relationship between patient characteristics and LS. PATIENTS AND METHODS The study included 59 patients after the Fontan procedure. Clinical examinations and laboratory tests were performed. According to the stage of LS, patients were divided into 2 subgroups: group 1 (METAVIR stages F1 and F2) and group 2 (METAVIR stages F3 and F4). The ratio of aspartate transaminase to alanine transaminase, aspartate transaminase‑‑to‑‑platelet ratio index (APRI), fibrosis‑‑4 (FIB‑‑4) score, and Forns index were assessed. RESULTS The median LS was 9.1 kPa (interquartile range, 3.9-18.5 kPa). Five patients (9%) demonstrated LS in stage F1; 14 (26%), F2; 28 (52%), F3; and 7 (13%), F4. Group 2 had significantly higher aspartate transaminase and γ‑‑glutamyltranspeptidase levels, APRI, FIB‑‑4, and Forns index, and lower platelet count than group 1. A canonical correlation analysis indicated that LS and thrombocytopenia were related to time from the Fontan procedure, age at procedure, and single ventricular ejection fraction. CONCLUSIONS We showed that adult patients after the Fontan procedure develop liver dysfunction. Time from surgery, age at procedure, and single ventricular ejection fraction are related to the degree of LS assessed by SWE. Finally, SWE, APRI, Forns index, and FIB‑4 score may help assess the degree of liver fibrosis.

Abstract
Background Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease and the population of ToF repair survivors is growing rapidly. Adults with repaired ToF develop late complications. The aim of this study was to describe and analyze long-term follow-up of patients with repaired ToF. Methods This is a retrospective cohort study. Consecutive 83 patients with repaired ToF who did not undergo pulmonary valve replacement were included. Mean age of all patients was 30.5 ± 10.7. There were 49 (59%) male. Patients were divided into two groups according to the time since the repair (< 25 years and ≥ 25 years). The electrocardiographic (ECG), cardiopulmonary exercise testing (CPET), echocardiographic and cardiac magnetic resonance (CMR) data were reviewed retrospectively. Results In CPET values were not significantly different in the two groups. In CMR volumes of left and right ventricles were not significantly different in the two groups. There were no differences between the groups in ventricular ejection fraction, mass of ventricles, or pulmonary regurgitation fraction. Among all the patients, ejection fraction and left and right ventricle mass, indexed pulmonary regurgitation volume measured by CMR did not correlate with the time since repair. In ECG among all the patients, ejection fraction of the RV, measured in CMR, negatively correlated with QRS duration (r = − 0.43; p < 0.001). There was a positive correlation between QRS duration and end diastolic volume of the RV (r = 0.30; p < 0.02), indexed end diastolic volume of the RV (r = 0.29; p = 0.04), RV mass (r = 0.36; p < 0.001) and left ventricle mass (r = 0.26; p = 0.04). Conclusion Long-term survival and clinical condition after surgical correction of ToF in infancy is generally good and the late functional status in ToF – operated patients could be excellent up to 25 years after the repair. QRS duration could be an utility and easy factor to assessment of right ventricular function. Trial registration The study protocol was approved by the local Ethics Committee. Each participant provided informed consent to participate in the study (license number 122.6120.88.2016 from 28.04.2016).

Abstract
BACKGROUND Opioidergic conditioning is well documented to trigger cardioprotection against ischemia/ reperfusion (I/R) injury. Previous studies on animal models have suggested that nitric oxide (NO) mediates the beneficial effect of opioids, but the role of NO in humans seems to be controversial. OBJECTIVES The aim of the study was to assess the influence of NO modulators on opioid-induced cardioprotection in the human myocardium. MATERIAL AND METHODS Trabeculae of the human right atria were electrically driven in an organ bath and subjected to simulated I/R injury. The non-selective inhibitor of nitric oxide synthase (NOS) - N-methyl-l-arginine (LNMMA), the donor of NO - S-Nitroso-N-acetylpenicillamine (SNAP) or morphine (in the amount of 10-4 M) were used at the time of re-oxygenation. The additional trabecula was subjected to the hypoxia protocol only (control). The contractility of the myocardium was assessed as the maximal force of a contraction (Amax), the rate of rise of the force of a contraction (Slope L) and the cardiac muscle relaxation - as the rate of decay of the force of a contraction (Slope T). RESULTS The application of 100 μM LNMMA resulted in the decrease of Amax, Slope L and Slope T during the re-oxygenation period as compared to control. The application of 10-4 M morphine and/or 100 μM SNAP resulted in a partial reversal of the detrimental influence of LNMMA. CONCLUSIONS At the re-oxygenation period, the blockade of NO synthesis has a deleterious effect on the systolic and diastolic function of the human myocardium as well as attenuates the beneficial effect of morphine conditioning.

Abstract
Background The Fontan procedure, performed for univentricular heart, may also include the technique of percutaneous fenestration to create a small atrial septal defect (ASD) and a right-to-left shunt. The aim of this study was to evaluate the long-term effects of fenestration in adult patients who had a Fontan procedure for univentricular heart. Material/Methods Fontan surgery was performed in 39 patients, including 19 (49%) patients with fenestration (Group I), and 20 (51%) patients without the fenestration procedure (Group II). Laboratory tests in both groups included echocardiography, plethysmography, cardiopulmonary exercise testing, and 24-hour Holter monitoring. Results Compared with patients in Group I, patients in Group II had a significantly increased level of N-terminal pro-brain natriuretic peptide (NT-proBNP) (p=0.04), alkaline phosphatase (ALP) (p=0.01) and a significant increase in frequency of atrial fibrillation (p=0.04). Patients in Group I had a significantly increased systemic ventricular ejection fraction (SVEF) (p=0.05) and increased heart rate (HR) (p=0.006), heart rate reserve (HRR) (p=0.02), ventilatory equivalent (VE) (p=0.01), and VO2 peak (p=0.05) on cardiopulmonary exercise testing (CPET). Renal, hematologic, and ventilatory parameters, and incidence of thromboembolism showed no significant differences between the groups. Conclusions Long-term follow-up of patients who underwent Fontan procedures with percutaneous fenestration had improved single ventricular function, lower NT-proBNP levels, improved exercise capacity, and reduced ALP levels. These findings indicate that percutaneous fenestration closure should be considered for adult patients who have undergone Fontan procedure for univentricular heart.

Abstract
UNLABELLED The coarctation of the aorta (CoA) is a congenital condition of the thoracic aorta. AIM The aim of the study was assessment of atherosclerosis risk factors in adult patients after surgical treatment of aortic coarctation. MATERIALS AND METHODS 58 patients (36 male, 22 female) at median age of 27.46 ±10.57 were compared with 30 healthy, age and sex matched volunteers. The arterial blood pressure, lipid profile, fasting glucose, inflammation markers and the lifestyle factors were analyzed. RESULTS CoA patients have higher systolic blood pressure 136.55±16.27 vs 123.47±10.34 mmHg, p<0.001, fasting glucose 4.95±0.5 vs 4.65±0.46 mmol/l p=0.002, hsCRP 1.03±0.12 vs 0.89±0.14 mg/l p=0.025 and fibrinogen 2.55±0.34 vs 1.98±0.28 g/l p<0.001. Hyperlipidemia is more common 44.8% vs 23.3% p=0.048, treated with statin. When comparing hypertensive patients (N=28) with normotensive ones (N=30), the patients with arterial hypertension are older 33.5±12.23 vs 25.73±7.12 p=0.004, have higher body weight 78.03±14.58 vs 68.7±14.29 p=0.017, in this group more common are: hypoplastic aortic arch 28.6% vs 6.7% p=0.027, recoarctation 39.3% vs 13.3% p=0.024, cardiovascular disease 14.3% vs 0% p=0.032 and family history 21.4% vs 3.3% p=0.034. CONCLUSIONS The coarctation of aorta is related to higher cardiovascular risk due to arterial hypertension, hyperlipidemia, higher glucose and inflammation markers levels when comparing with healthy population.

Abstract
AIM The aim of the study was to assess the type and frequency of prevalence of cardiac symptoms in patients with pulmonary sarcoidosis. MATERIALS AND METHODS The study group consisted of 54 patients (21 female, 33 male), with biopsy-proven pulmonary sarcoidosis. Mean age was 45.85 +/-11.77 years. According to time passed from diagnosis of sarcoidosis patients were divided into 2 subgroups. Additionally, age, sex, left ventricular ejection fraction, cigarette smoking and comorbidities were analyzed. Course and stage of sarcoidosis were also included in the analysis. RESULTS The frequency of cardiovascular symptoms in the study group was 87.04%. 59.26% of patients reported chest pain, the same subjects reported dyspnoea. 48.15% of respondents reported heart palpitations, 33.33% pre-syncope states, 12.96% syncope, and 37.04% edema of lower limbs. There were no statistically significant differences in the incidence of analyzed symptoms, depending on the duration of lung sarcoidosis. CONCLUSIONS Patients with pulmonary sarcoidosis who report cardiovascular symptoms require further diagnostics.

Abstract
BACKGROUND In the period from 2003 to the end of 2015, 96 Norwood I procedures were performed in the Paediatric Heart Surgery Department in Katowice, Poland, in children with hypoplastic left heart syndrome (HLHS). AIM This paper presents a retrospective analysis of early surgical results. METHODS The patients consisted of two groups: group I included 59 children operated on in the years 2003-2012, in whom the stage I Norwood procedure with the Sano modification was performed with the aortic arch reconstructed by use of a ho-mogenous pulmonary artery patch or a bovine pericardial patch. Group II included 37 children after our modification of the Norwood I procedure, in which the aortic arch was reconstructed with an extracellular matrix patch and bilateral pulmonary artery banding was done. RESULTS Aortic cross-clamping time was significantly shorter in group II (mean 52; range 38-62 min) than in group I (mean 57; range 39-72 min; p < 0.009). Eighteen (30.5%) children in group I and six (16.2%) in group II died. Although this dif-ference did not reach statistical significance (p = 0.12), it suggested that improved outcomes with the modified procedure are possible. The cause of death in group I was significantly more frequently due to massive postoperative bleeding (n = 6; 33.3%) than in group II (n = 1; 16.7%; p = 0.046). CONCLUSIONS The introduction of this new surgical technique reduced postoperative bleeding rates, shortened the operation time, and might improve the mortality rate in the first-stage surgical treatment of children with HLHS.

Abstract
UNLABELLED Although 85% of patients with univentricular heart after Fontan procedure survive twenty years after operation, the procedure alone seems to be an inadequate treatment as a permanent clinical solution. Patients with a "Fontan physiology" additionally have to face a various extra-cardiac complications, including thyroid, liver and kidney dysfunction, which are not only potentially life-threatening, but also can potentiate the circulatory insufficiency. AIM The aim of the study was to assess a multiorgan dysfunction in adult patients after Fontan operation in long term follow-up and compare to healthy controls. MATERIALS AND METHODS 54 patients after Fontan procedure (age=25.1±7 years, time after operation =19.8±6.3 years, age at the time of the procedure =5.3±4.3 years) and 30 controls (26.2±5.8 years) were included to the study. Clinical and laboratory examinations were performed including: hematologic, hepatic, renal and thyroid function tests. The following laboratory tests were performed: red blood cell counts (RBC), hematocrit (Ht), hemoglobin (Hb), platelets count, red blood cell distribution width (RDW), iron level; Btype natriuretic peptide (NT-proBNP), proteinogram blood test, alanine aminotransferase (ALT), aspartate aminotransferase (AST), gammaglutamyl transpeptidase (GGTP), alkaline phosphatase (ALP), total bilirubin, alpha fetoprotein (AFP) level. Furthermore creatinine level; cystatin C, urine albumin to creatynine ratio (ACR) and urinalysis were assessed. To assess a thyroid function free triiodothyronine (fT3), free thyroxine (fT4) and thyroid stimulating hormone (TSH) were measured. Furthermore an abdomen ultrasonography was performed. RESULTS In terms of the hematological disorders Fontan patients had a statistically significant higher level of RBC (5.6±0,8 vs 4.8±0.4 109/μl; p<0,001), Hb (16.5±2.8 vs 14.2±1.2 g/dl; p<0,001), HCT (48.7±8.1 vs 42.1±3 %; p<0,001), RDW (14±2.6 vs 12.8±0.5 %; p=0.001), as compared to control group, while PLT level was statistically lower in Fontan group (156.2±61.4 vs 224.2±48 103/μl; p<0,0001). Hepatic parameters in Fontan patients were statistically significant higher, as depicted by the level of: ALT (28.5±10.5 vs 21.5±6 U/l, p<0,001), GGTP (85.6±48.8 vs 19.3±9 U/ l, p<0,001), total bilirubin (26.6±24.8 vs 8.9±4.7 μmol/l; p<0,001), ALP (82.4±31.5 vs 51.2±16 U/l; p<0,001) and INR (1.21±0.3 vs 0.98±0.2; p<0,001). Other parameters such as: AFP, total protein and albumin level did not statistically significantly differ. Additionally five patients (9%) according to clinical symptoms and serum albumin level were diagnosed protein-losing enteropathy (PLE). There was no difference in serum creatinine level between Fontan patients and control group (79.6±23.6 vs 75.9±18.9 μmol/l; p=0.8) as well as in uric acid level (342.7±102 vs 303±105 μmol/l; p=0.2). Cystatin C level was significantly higher in Fontan group in comparison to controls (1.1±0.6 vs 0.8±0.1 ng/ml; p=0,05). Furthermore four Fontan patients (7%) had abnormal microalbumin/creatynine ratio. Urine testing preformed in 30 Fontan patients pointed to 7 cases (23%) where hematuria was observed, while proteinuria was detected in 4 cases (13%) and urobilinogen in 2 (7%). Dysfunction of the thyroid gland was found in 30% of patients after Fontan operation (7% in the control group, p=0,034). Among disorders of the thyroid gland: 13% of patients were diagnosed with hyperthyroidism, 54% diagnosed with subclinical hypothyroidism, and the remaining 33% with hypothyroidism. CONCLUSIONS Our study show that adult patients after Fontan procedure in long-term follow are exposed to multiorgan complications including hematological, liver, kidney and thyroid dysfunction.

Preoperative single ventricle function determines early outcome after second-stage palliation of single ventricle heart. Cardiovasc Ultrasound 2017; 15:21. [PMID: 28893257 PMCID: PMC5594433 DOI: 10.1186/s12947-017-0114-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Accepted: 09/05/2017] [Indexed: 11/21/2022] Open
Abstract
Background Second-stage palliation with hemi-Fontan or bidirectional Glenn procedures has improved the outcomes of patients treated for single-ventricle heart disease. The aim of this study was to retrospectively analyze risk factors for death after second-stage palliation of single-ventricle heart and to compare therapeutic results achieved with the hemi-Fontan and bidirectional Glenn procedures. Material and methods We analyzed 60 patients who had undergone second-stage palliation for single-ventricle heart. Group HF consisted of 23 (38.3%) children who had been operated with the hemi-Fontan method; Group BDG consisted of 37 (61.7%) who had been operated with the bidirectional Glenn method. The analysis focused on 30-day postoperative mortality rates, clinical and echocardiographic data, and early complications. Results The patients’ ages at the time of repair was 33 ± 11.2 weeks; weight was 6.7 ± 1.2 kg. The most common anatomic subtype was hypoplastic left heart syndrome, in 36 (60%) patients. The early mortality rate was 13.3%. Significant preoperative atrioventricular valve regurgitation, single-ventricle heart dysfunction, pneumonia/sepsis, and arrhythmias were associated with higher mortality rates after second-stage palliation. Multivariate analysis identified significant preoperative single-ventricle heart dysfunction as an independent predictor of early death after second-stage palliation. No differences were found in the analyzed variables after bidirectional Glenn compared with hemi-Fontan procedures. Conclusion Significant preoperative atrioventricular valve regurgitation, arrhythmias and pneumonia/sepsis are closely correlated with mortality in patients with single-ventricle heart after second-stage palliation. Preoperative significant single-ventricle heart dysfunction is an independent mortality predictor in this group of patients. There are no differences in clinical, echocardiographic data, or outcomes in patients treated with the hemi-Fontan compared with bidirectional Glenn procedures.

Abstract
UNLABELLED Exertional dyspnea is a common manifestation of sarcoidosis. Cardiopulmonary exercise testing (CPET) is a useful tool to evaluate exercise tolerance of sarcoid patients. AIM The aim of the study was to evaluate of exercise capacity in patients with pulmonary sarcoidosis with regard to duration of the disease. Analysis of differences in physical tolerance between patients with cardiac sarcoidosis and without cardiac sarcoidosis. MATERIALS AND METHODS 39 patients diagnosed with pulmonary sarcoidosis were enrolled to our study. Cardiopulmonary exercise test was used to assess exercise capacity. According to time passed from diagnosis of sarcoidosis patients were grouped into 2 groups. Cardiac sarcoidosis was diagnosed in 9 subjects (23.07%). The control group consisted of 33 healthy volunteers. RESULTS The results of the ergospirometry test in patients with lung sarcoidosis showed statistically significant differences in comparison to the control group. The age of patients with pulmonary sarcoidosis correlated negatively with maximal heart rate, oxygen consumption at peak exercise and at anaerobic threshold, breathing frequency at peak exercise, minute ventilation at peak exercise and metabolic equivalent. There was a negative, statistically significant correlation between the oxygen pulse at the peak of exercise and the treatment of steroids in the past. CONCLUSIONS Exercise limitation in patients with pulmonary sarcoidosis is a consequence of both ventilatory and cardiocirculatory impairment. Patients with longer disease history of sarcoidosis achieved worse results at cardiopulmonary exercise test than patients with shorter disease history. Trend towards worse exercise tolerance in patients with cardiac sarcoidosis compared to patients without cardiac sarcoidosis was observed.

Abstract
Objectives Investigate the effects of left and right ventricular function and severity of pulmonary valve regurgitation, quantified by cardiac magnetic resonance (CMR), on exercise tolerance in adult patients who underwent ToF repair at a young age. Methods This is a retrospective cohort study of 52 patients after ToF surgery and 33 age- and sex-matched healthy volunteers. CMR and cardiopulmonary exercise testing (CPET) were performed on all patients; CPET was performed on control subjects. Results The main finding of CPET was a severe decrease in oxygen uptake at peak exercise VO2peak in TOF patients. The patients were characterized also by lower pulse O2peak and heart rate at peak exercise. Ejection fraction of the right and left ventricles was correlated (r = 0,32; p = 0,03). Left ventricle ejection fraction was negatively correlated with right ventricular volumes (r = −0,34; p = 0,01) and right ventricular mass (r = −046; p < 0,00). Right ventricular mass was positively correlated with left ventricular variables (left ventricle end diastolic volume, r = 0,43; p = 0,002; left ventricle end systolic volume, r = 0,54; p < 0,00) as was VO2peak: LVEDV (r = 0,38; p = 0,01); LVESV (r = 0,33; p = 0,03) and LV mass (r = 0,42; p = 0,006). Conclusion Exercise intolerance in adults with repaired ToF is markedly depressed. The decreased exercise capacity is correlated with impaired RV function and may be associated also with LV dysfunction, which suggests right-to-left ventricular interaction.

Abstract
Background Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac anomaly which requires surgical treatment, which improves left ventricular function and clinical outcomes. The definitive diagnosis of ALCAPA is based on coronary angiography, however, noninvasive visualization of the origin of the coronary artery is often helpful in the diagnosis of ALCAPA. Objectives The purpose of this study was to evaluate noninvasive techniques for the diagnosis of ALCAPA, and present the clinical outcomes in adults after surgical correction of ALCAPA. Methods Medical charts of five patients with ALCAPA treated at the John Paul II Hospital in Cracow between 2004 and 2012 were analyzed retrospectively. Noninvasive imaging techniques were used to visualize coronary vessels preoperatively. Patients were followed one year after the operation with echocardiograms and assessment of the New York Heart Association functional class. Results Computed tomography showed ALCAPA in four patients. Magnetic resonance imaging showed abnormal left ventricle remodeling suggestive of ischemia of the anterior cardiac wall. Myocardial perfusion imaging revealed ischemia of the middle and periapical segments of the anterior and anterolateral wall of the left ventricle in two patients. Postoperatively, patients had symptomatic improvement, but there was no statistically significant difference in mean ejection fraction. Conclusions Noninvasive techniques can be used to visualize the origin of the coronary arteries and characterize their morphology. Long-term follow-up of adult patients after surgical correction of ALCAPA is not well documented in the literature, but surgical treatment revealed beneficial short-term effects and symptoms relief.

Abstract
Background:
Eisenmenger syndrome is associated with substantial morbidity and mortality. There is no consensus, however, on mortality risk stratification. We aimed to investigate survival and predictors of death in a large, contemporary cohort of Eisenmenger syndrome patients.
Methods:
In a multicenter approach, we identified adults with Eisenmenger syndrome under follow-up between 2000 and 2015. We examined survival and its association with clinical, electrocardiographic, echocardiographic, and laboratory parameters.
Results:
We studied 1098 patients (median age, 34.4 years; range, 16.1–84.4 years; 65.1% female; 31.9% with Down syndrome). The majority had a posttricuspid defect (n=643, 58.6%), followed by patients with a complex (n=315, 28.7%) and pretricuspid lesion (n=140, 12.7%). Over a median follow-up of 3.1 years (interquartile range, 1.4–5.9), allowing for 4361.6 patient-years observation, 278 patients died and 6 underwent transplantation. Twelve parameters emerged as significant predictors of death on univariable analysis. On multivariable Cox regression analysis, only age (hazard ratio [HR], 1.41/10 years; 95% confidence interval [CI], 1.24–1.59;
P
<0.001), pretricuspid shunt (HR, 1.56; 95% CI, 1.02–2.39;
P
=0.041), oxygen saturation at rest (HR, 0.53/10%; 95% CI, 0.43–0.65;
P
<0.001), presence of sinus rhythm (HR, 0.53; 95% CI, 0.32–0.88;
P
=0.013), and presence of pericardial effusion (HR, 2.41; 95% CI, 1.59–3.66;
P
<0.001) remained significant predictors of death.
Conclusions:
There is significant premature mortality among contemporary adults with Eisenmenger syndrome. We report, herewith, a multivariable mortality risk stratification model based on 5 simple, noninvasive predictors of death in this population.

Abstract
BACKGROUND The aim of this study was to prospectively perform ambulatory 24-h ECG monitoring to assess the effects of transcatheter closure of atrial septal defect (ASD). METHODS AND RESULTS A total of 235 consecutive subjects (female, n=163; male, n=72; age, 44.6±14.4 years) were enrolled in the study, who were due undergo ASD closure. Holter monitoring was performed before procedure and at 1, 6 and 12 months of follow-up. During the procedure transient supraventricular arrhythmia occurred in 8 patients (3.4%), and bradycardia in 3 (1.3%). In 3 patients (1.3%) an episode of atrial fibrillation occurred in the first hour after the procedure. In 8 patients (3.4%) transient first-degree atrioventricular block was noted. A significant increase in number of supraventricular extrasystoles (SVES)/24 h was noted 1 month after the procedure (P<0.001). On multiple forward stepwise regression analysis, device size and fluoroscopy time had an influence on increase in number of SVES seen 1 month after the procedure (P<0.001). CONCLUSIONS Transcatheter closure of ASD is associated with a transient increase in supraventricular premature beats and a small risk of conduction abnormalities and paroxysmal atrial fibrillation in early follow-up. Transcatheter closure of ASD does not reduce arrhythmia that appears prior to ASD closure. Larger device size and longer procedure time are associated with increased risk of supraventricular arrhythmia on early follow-up.

Abstract
Background The study aimed to assess the level of plasma Endothelin-1 (ET-1) in patients before and after transcatheter closure of atrial septal defect (ASD) and to evaluate the usefulness of measuring ET-1 levels for the diagnosis and selection of candidates for ASD closure. Methods 80 patients (55 F, 25 M), mean age 42,2 ± 11,5 years were enrolled for an attempt at ASD closure. A group of 19 healthy volunteers, (12 F, 7 M) mean age 39.2 ± 9.15 served as controls. All ASD patients underwent: clinical and echocardiographic study and cardiopulmonary exercise test. ET-1 levels were measured before and after closure. Whole blood was collected from femoral artery and vein and from pulmonary artery during cardiac catheterization. Results ET-1 levels at peripheral artery and vein in ASD patients were significantly higher than in the volunteers (p < 0.0001). The ASD subjects with highest ET-1 level presented the larger area of right ventricle and right atrium and higher pulmonary artery systolic pressure(p < 0.05). The ASD subjects with lower ET-1 level demonstrated longer time of exercise and higher peak oxygen consumption (p < 0.05). There was a decrease of ET-1 at peripheral artery (5.128 ± 8.8 vs. 2.22 ± 6.2; p < 0.001) and at peripheral vein (4.401 ± 3.33 vs. 2.05 ± 1.35; p < 0.001) within 48 hours after ASD closure, as compared to the baseline data. After 6 and 12 months farther drop in ET-1 level was observed. Conclusions 1. The level of ET-1 in ASD patients is elevated in compare to healthy subject. 2. The significant reduction of ET-1 level is observed after percutaneous closure of ASD. 3. Elevated level of ET-1 in patients with ASD is associated with right heart enlargement. 4. Measurements of ET-1 may be a supplemental diagnostic tool and may be helpful in establishing indications for defect closure.

Transcranial Doppler ultrasonography should it be the first choice for persistent foramen ovale screening? Cardiovasc Ultrasound 2014; 12:16.

Abstract
Background Persistent foramen ovale (PFO) is considered a cause of cryptogenic stroke and a risk factor for neurological events in young patients. The reference standard for identifying a PFO is contrast-enhanced transesophageal echocardiography (TEE). The goal of this study was to evaluate the feasibility of transcranial color Doppler (TCD) and its diagnostic sensitivity compared with TEE. Methods We investigated 420 patients admitted to our department with cryptogenic stroke, transient ischemic attacks or other neurological symptoms. All patients underwent TCD and TEE evaluation. TCD and TEE examinations were performed according to a standardized procedure: air-mixed saline was injected into the right antecubital vein three times, while the Doppler signal was recorded during the Valsalva maneuver. During TCD the passage of contrast into the right-middle cerebral artery was recorded 25 seconds following the Valsalva maneuver. Results We detected a right-to-left shunt in 220 patients (52.3%) and no-shunts in 159 patients (37.9%) with both TCD and TEE. In 20 (4.8%) patients TEE did not reveal contrast passage which was then detected by TCD. In 21 (5.0%) patients only TEE revealed a PFO. The feasibility of both methods was 100%. TCD had a sensitivity of 95% and a specificity of 92% in the diagnosis of PFO. Conclusions TCD has a relatively good sensitivity and specificity. TCD and TEE are complementary diagnostic tests for PFO, but TCD should be recommended as the first choice for screening because of its simplicity, non-invasive character, low cost and high feasibility.

Abstract
Background Chronic anticoagulation is a standard of care in idiopathic pulmonary arterial hypertension (IPAH). However, hemostatic abnormalities in this disease remain poorly understood. Therefore, we aimed to study markers of thrombogenesis and fibrinolysis in patients with IPAH. Methods We studied 27 consecutive patients (67% female) with IPAH aged 50.0 years (IQR: 41.0 - 65.0) and 16 controls without pulmonary hypertension. Prothrombin fragment 1+2 (F1+2) and thrombin-antithrombin (TAT) complexes were measured to assess thrombogenesis; tissue-type plasminogen activator (tPA) antigen and plasmin-anti-plasmin complex to characterize activation of fibrinolysis; plasminogen activator inhibitor 1 (PAI-1) to measure inhibition of fibrinolysis; and endothelin-1 (ET-1) and interleukin-6 (IL-6) to assess endothelial activation and systemic inflammation, respectively. In addition, in treatment-naive IPAH patients these markers were assessed after 3 months of PAH-specific therapies. Results TPA (10.1[6.8-15.8] vs 5.2[3.3-7.3] ng/ml, p<0.001), plasmin-anti-plasmin (91.5[60.3-94.2] vs 55.8[51.1-64.9] ng/ml, p<0.001), IL-6 (4.9[2.5-7.9] vs 2.1[1.3-3.8] pg/ml, p=0.001) and ET-1 (3.7 [3.3-4.5] vs 3.4[3.1-3.5], p= 0.03) were higher in patients with IPAH than in controls. In IPAH patients plasmin-anti-plasmin and tPA correlated positively with IL-6 (r=0.39, p=0.04 and r=0.63, p<0.001, respectively) and ET-1 (r=0.55, p=0.003 and r=0.59, p=0.001, respectively). No correlation was found between tPA or plasmin-anti-plasmin and markers of thrombogenesis. Plasmin-anti-plasmin decreased after 3 months of PAH specific therapy while the other markers remained unchanged. Conclusions In the present study we showed that markers of fibrynolysis were elevated in patients with IPAH however we did not find a clear evidence for increased thrombogenesis in this group of patients. Fibrinolysis, inflammation, and endothelial activation were closely interrelated in IPAH.

Abstract
BACKGROUND Incidence of patent foramen ovale (PFO) has been estimated at 25% in the general population and 6% for larger defects. Data on the relationship between PFO morphology and the risk of stroke are limited. PFO closure has become a common practice in many centres, although recent guidelines limit indications for such treatment to patients with cryptogenic (recurrent) stroke. AIM To investigate whether PFO morphology assessed by transoesophageal echocardiography (TOE) differed between patients with symptoms and those who had an asymptomatic PFO. METHODS We analysed 88 consecutive patients (48 female, 40 male; mean age 36.1 ± 16.2 [range 18-59] years) who underwent TOE before transcatheter PFO closure due to a cryptogenic cerebrovascular event (Group I) and compared them to 88 consecutive patients (49 female, 39 male; mean age 35.7 ± 14.2 [range 18-57] years) with an asymptomatic PFO found incidentally on TOE (Group II). The diagnosis of stroke was based on the occurrence of a new acute focal neurological deficit, with neurological signs and symptoms persisting for >24 h, subsequently confirmed by computed tomography and/or magnetic resonance imaging. Multiplane TOE was conducted as per guidelines using commercially available instruments. The interatrial septum was viewed in the transverse midoesophageal 4-chamber view and the longitudinal biatrial-bicaval view. PFO was diagnosed with intravenous injections of agitated saline while the patient was at rest and during the Valsalva manoeuvre. We analysed PFO size (resting and maximal separation of the septum primum and secundum during the Valsalva manoeuvre), tunnel length (maximal overlap of the septum primum and secundum), presence of an atrial septal aneurysm (excursion 〉 15 mm), shunt severity (mild: 3-5, moderate: 6-25, severe 〉 25 microbubbles) and prominence of the Eustachian valve. RESULTS The two groups did not differ with respect to age and sex distribution. Group I showed larger PFO size (maximal separation 3.9 ± 1.4 vs. 1.3 ± 1.3 mm, p 〈 0.0001), longer tunnel length (14 ± 6 vs. 12 ± 5.5 mm, p 〈 0.05) and a greater frequency of atrial septal aneurysm (55% vs. 15%, p 〈 0.0001) compared to Group II (controls). Group I was also characterised by a higher proportion of large PFOs (≤ 4 mm; 50% vs. 18%, p 〈 0.001) and severe shunt (40% vs. 2%, p 〈 0.0001). CONCLUSIONS PFO in symptomatic patients is larger in size, has a longer tunnel and is more frequently associated with atrial septal aneurysm. Asymptomatic patients with PFO characteristics similar to that seen in stroke patients require more careful clinical evaluation. It may be debated whether such patients should be recruited to prospective trials to evaluate indications for PFO closure in stroke prevention.
