RESUMO
Background: The management of patients with acute pulmonary embolism (aPE) depends on the severity of aPE. The timing of death in various aPE risk subgroups is only partially known. Methods: 1618 patients with an objectively established aPE diagnosis with computed tomography pulmonary angiography enrolled in the regional PE registry were included in the study. According to ESC criteria, patients were stratified at admission to the hospital in four risk strata. The timing of PE-related and non-PE-related deaths was analyzed regarding mortality risk. Results: PE-related, and non-PE-related hospital death rates were 1.1 % and 1.5 % in low, 1.1 % and 4.8 % in intermediate-low, 8.1 % and 5.9 % in intermediate-high, and 27.7 % and 6.9 % in high-risk groups, respectively. The median time of PE-related and non-PE-related death across the PE mortality risk were: 4 (1.7-7.5) and 7.0 (4-14.7) days in low, 1.5 (1.0-9.5) and 11.5 (2.0-21.0) days in intermediate-low, 4.0 (2.0-9.0) and 9.0 (5.7-18.2) days in intermediate-high, 2.0 (1.0-4.75) and 7.0 (3.0-21.2) days in high-risk subgroups. 48.2 % and 17.1 % of patients who died in the high and intermediate-high risks died during the first hospital day. After the 6th hospitalization day, PE-related deaths were recorded in 43.9 % of deaths from intermediate-high and 17.9 % from high-risk subgroups. Conclusion: PE-related mortality is prominent on the first hospitalization day in high and intermediate-high-risk PE. A substantial proportion of intermediate-high and high-risk patient's PE deaths occurred after the first 6 days of hospitalization.
RESUMO
[Purpose] The purpose of this study was to determine the effects of short-term exercise training on the cardiorespiratory fitness (CRF) of individuals suffering from myocardial infarction. [Subjects] A total of 60 participants were divided into experimental (EXP; n=30, mean age 56.7 ± 2.8â years, body mass 80.7 ± 10.7â kg, body height 171.9 ± 7.2â cm) and control (CON; n=30, mean age 56.5 ± 3.1â years, body mass 84.4 ± 12.4â kg, body height 171.5 ± 12.4â cm) groups. [Methods] The members of the EXP group took part in an organized daily physical exercise program (Monday through Sunday), for a period of 3 weeks. The exercise program consisted of 60â min daily specialized fitness exercises with an intensity ranging from 55-70% of the maximum heart rate, which was determined by test on a bicycle ergometer. The effects of the exercise were monitored by means of the following parameters: maximum oxygen uptake (VO2peak), resting heart rate, systolic blood pressure and diastolic blood pressure. [Results] The results indicate statistically significant post-exercise improvements in heart rate, relative oxygen uptake and systolic blood pressure, among the members of the EXP group. The results indicate that at the initial measurement of cardiorespiratory fitness no statistically significant differences were found between the groups at the multivariate level (Wilk's λ=0.83), while statistically significant differences in the cardiorespiratory fitness were found at the final measurement (Wil's λ=0.430). [Conclusion] The obtained results indicate that the exercise program, which lasted for a period of 21 days, though shorter in duration than other programs still led to statistically significant changes in the CRF of individuals suffering from MI.
RESUMO
BACKGROUND: The incidence of the signs and symptoms of acute pulmonary embolism (PE) according to mortality risk, age and sex has been partly explored. PATIENTS AND METHODS: A total of 1242 patients diagnosed with acute PE and included in the Regional Pulmonary Embolism Registry were enrolled in the study. Patients were classified as low risk, intermediate risk or high risk according to the European Society of Cardiology mortality risk model. The incidence of the signs and symptoms of acute PE at presentation with respect to sex, age, and PE severity was investigated. RESULTS: The incidence of haemoptysis was higher in younger men with intermediate-risk (11.7% vs 7.5% vs 5.9% vs 2.3%; p=0.01) and high-risk PE (13.8% vs 2.5% vs 0.0% vs 3.1%; p=0.031) than in older men and women. The frequency of symptomatic deep vein thrombosis was not significantly different between subgroups. Older women with low-risk PE presented with chest pain less commonly (35.8% vs 55.8% vs 48.8% vs 51.9%, respectively; p=0.023) than men and younger women. However, younger women had a higher incidence of chest pain in the lower-risk PE group than in the intermediate-risk and high-risk PE subgroups (51.9%, 31.4% and 27.8%, respectively; p=0.001). The incidence of dyspnoea (except in older men), syncope and tachycardia increased with the risk of PE in all subgroups (p<0.01). In the low-risk PE group, syncope was present more often in older men and women than in younger patients (15.5% vs 11.3% vs 4.5% vs 4.5%; p=0.009). The incidence of pneumonia was higher in younger men with low-risk PE (31.8% vs<16% in the other subgroups, p<0.001). CONCLUSION: Haemoptysis and pneumonia are prominent features of acute PE in younger men, whereas older patients more frequently have syncope with low-risk PE. Dyspnoea, syncope and tachycardia are symptoms of high-risk PE irrespective of sex and age.

This study aimed to assess the prognostic significance of total leukocyte count (TLC) and hemoglobin (Hb) levels upon admission for patients with acute pulmonary embolism (PE), considering the European Society of Cardiology (ESC) model for mortality risk. 1622 patients from a regional PE registry were included. Decision tree statistics were employed to evaluate the prognostic value of TLC and Hb, both independently and in conjunction with the ESC model. The results indicated all-cause and PE-related in-hospital mortality rates of 10.7% and 6.5%, respectively. Subgrouping patients based on TLC cut-off values (≤11.2, 11.2-16.84, >16.84 × 109/L) revealed increasing all-cause mortality risks (7.0%, 11.8%, 30.2%). Incorporating Hb levels (≤126 g/L or above) further stratified the lowest risk group into two strata with all-cause mortality rates of 10.1% and 4.7%. Similar trends were observed for PE-related mortality. Notably, TLC improved risk assessment for intermediate-high-risk patients within the ESC model, while Hb levels enhanced mortality risk stratification for lower-risk PE patients in the ESC model for all-cause mortality. In conclusion, TLC and Hb levels upon admission can refine the ESC model's mortality risk classification for patients with acute PE, providing valuable insights for improved patient management.
RESUMO
BACKGROUND: Patients with acute pulmonary embolism (PE) may have various types of atrial fibrillation (AF). The role of AF in hemodynamic states and outcomes may differ between men and women. METHODS: In total, 1600 patients (743 males and 857 females) with acute PE were enrolled in this study. The severity of PE was assessed using the European Society of Cardiology (ESC) mortality risk model. Patients were allocated into three groups according to their electrocardiography recordings taken during hospitalization: sinus rhythm, new-onset paroxysmal AF, and persistent/permanent AF. The association between the types of AF and all-cause hospital mortality was tested using regression models and net reclassification index (NRI) and integrated discrimination index (IDI) statistics with respect to sex. RESULTS: There were no differences between the frequencies of the types of AF between men and women: 8.1% vs. 9.1% and 7.5% vs. 7.5% (p = 0.766) for paroxysmal and persistent/permanent AF, respectively. We found that the rates of paroxysmal AF significantly increased across the mortality risk strata in both sexes. Among the types of AF, the presence of paroxysmal AF had a predictive value for all-cause hospital mortality independent of mortality risk and age in women only (adjusted HR, 2.072; 95% CI, 1.274-3.371; p = 0.003). Adding paroxysmal AF to the ESC risk model did not improve the reclassification of patient risk for the prediction of all-cause mortality, but instead enhanced the discriminative power of the existing model in women only (NRI, not significant; IDI, 0.022 (95% CI, 0.004-0.063); p = 0.013). CONCLUSION: The occurrence of paroxysmal AF in female patients with acute PE has predictive value for all-cause hospital mortality independent of age and mortality risk.
RESUMO
BACKGROUND: Estimation of bleeding risk is an unmet need for individualized therapy in acute pulmonary embolism (PE) patients with increased mortality risk. METHODS: We analyzed the association between various patients' characteristics and occurrence of major bleeding (MB) according to the modified International Society of Thrombosis and Hemostasis (ISTH) criteria ("overt" bleeding is the only modification from the original criteria) at 7 days from admission to the hospital and thrombolytic therapy with a tissue-plasminogen activator (tPA). Pulmonary embolism bleeding score index (PEBSI) was created using multivariate regression analyses, and finely, dichotomous index was used for the discrimination of patients with low risk for MB from those with high risk. RESULTS: During the 6-year period (2015-2021) 367 PE patients were treated with tPA and included in the Regional PE registry. Among them, 29 (7.9%) fulfilled the criteria for MB. Five factors were identified as significantly associated with MB and were used to build the PEBSI score: previous bleeding, recent surgery, diabetes, the use of drugs that could be associated with bleeding, and anemia. PEBSI score showed c-index for 7-day MB 0.794 (95CI% 0.698-0.889). Patients with PEBSI scores of 0 or 1 had a low risk for MB (2.8%) and those with scores>1 had a high risk for MB (18.6%) (p < 0.001). Internal validation of PEBSI score using a randomly, equally split method confirmed the discriminative value of the PEBSI score. CONCLUSION: Novel PEBSI score has significant power to discriminate patients with low risk for MB on thrombolytic therapy from those with high risk.

Background: Published data regarding the impact of obesity on COVID-19 outcomes are inconsistent. However, in most studies, body composition was assessed using body mass index (BMI) alone, thus neglecting the presence and distribution of adipose tissue. Therefore, we aimed to investigate the impact of body and visceral fat on COVID-19 outcomes. Methods: Observational, prospective cohort study included 216 consecutive COVID-19 patients hospitalized at University Clinical Center Kragujevac (Serbia) from October to December 2021. Body composition was assessed using the BMI, body fat percentage (%BF), and visceral fat (VF) via bioelectrical impedance analysis (BIA). In addition to anthropometric measurements, variables in the research were socio-demographic and medical history data, as well as admission inflammatory biomarkers. Primary end-points were fatal outcomes and intensive care unit (ICU) admission. Results: The overall prevalence of obesity was 39.3% according to BMI and 50.9% according to % BF, while 38.4% of patients had very high VF levels. After adjusting odds ratio values for cofounding variables and obesity-related conditions, all three anthropometric parameters were significant predictors of primary end-points. However, we note that % BF and VF, compared to BMI, were stronger predictors of both mortality (aOR 3.353, aOR 3.05, and aOR 2.387, respectively) and ICU admission [adjusted odds ratio (aOR) 7.141, aOR 3.424, and aOR 3.133, respectively]. Conclusion: Obesity is linked with COVID-19 mortality and ICU admission, with BIA measurements being stronger predictors of outcome compared to BMI use alone.
RESUMO
AIMS: To examine the relationship between admission glucose (AG) level and short-term in-hospital mortality and to investigate the association between hyperglycemia and major bleeding in PE patients with and without DMT2. METHODS: We evaluated 1165 patients with diagnosed acute PE with multi-detector computed tomography pulmonary angiography (MDCT-PA) enrolled in the Regional multicenter PE registry (REPER). The study population was classified to patients with diabetes mellitus type 2 (DMT2) and those without diabetes. According to quartiles of AG patients, both groups separately were categorized into four subgroups (DMT2 I: < 7.5 mmol/L; II: 7.5-10.0 mmol/L; III: 10.0-15.7 mmol/L; IV: > 15.7 mmol/L and (non-DMT2 I: < 5.5 mmol/L; II: 5.5-6.3 mmol/L; III: 6.3-7.9 mmol/L; IV: > 7.9 mmol/L). RESULTS: All-cause mortality was higher in the DMT2 group (9.5% vs. 18.2%, p < 0.001), and PE-cause mortality was 6% for the patients without DMT2 and 12.4% for DMT2 patients (p = 0.02). The patients in the fourth AG quartiles in both groups, without DMT2 and with DMT2, had significantly higher all-cause and PE-cause in-hospital mortality compared with the first quartile. Rates of major bleeding were similar between the groups. On the multivariable analysis, after adjusting for age, gender and mortality risk, the adherence in the fourth AG quartile had an independent predictive value for all-cause death (HR 2.476, 95% CI 1.017-6.027) only in DM patients. CONCLUSION: In our cohort of patients with acute PE, diabetes was associated with increased rates for all-cause and PE-cause mortality.

BACKGROUND: Deep vein thrombosis (DVT) can be symptomatic or asymptomatic in patients with acute pulmonary embolism (PE). The prognostic value of the symptomatic DVT at the presentation regarding the prognosis of PE is unknown. METHODS: Data were extracted from the REgional Pulmonary Embolism Registry (REPER) which enrolled 1604 hospitalized patients after multidetector computed tomography (MDCT) diagnosed symptomatic acute PE. According to the ESC risk model, patients were classified into four subgroups. Patients who had leg edema with or without pain, and patients with leg pain and DVT confirmed by compression ultrasound were considered to have symptomatic DVT. This study aimed to compare all-cause hospital mortality between patients with symptomatic DVT and patients without symptoms or signs of DVT across the PE risk stratums. RESULTS: All-cause mortality in patients with symptomatic DVT compared to those who had no symptoms or signs of DVT were 2/196 (1.0%) vs. 11/316 (3.5%), P=0.145, 4/129 (3.1%) vs. 17/228 (7.5%), P=0.106, 14/196 (7.1%) vs. 54/290 (18.6%), P<0.001 and 16/55 (29.1%) vs. 51/139 (36.7%), P=0.402 in patients with low, intermediate-low, intermediate-high and high-risk PE, respectively. In multivariate analysis symptomatic DVT was associated with decreased in-hospital mortality only in patients with intermediate-high PE (OR 0.320, 95%CI 0.164-0.627; P=0.001). Intermediate-high risk PE patients with symptomatic DVT who were treated with thrombolysis had significantly lower hospital mortality than patients without symptoms or signs of DVT (2.2% vs. 11.4%, P=0.003). CONCLUSIONS: Intermediate-high risk PE patients with symptomatic DVT at presentation may benefit from thrombolysis and have lower hospital all-cause mortality in such circumstances.

INTRODUCTION: Recent studies report that syncope is not a significant predictor of 30-day mortality in pulmonary embolism (PE) patients, yet some data suggest sex-related differences may be relevant. OBJECTIVES: To evaluate sex-specific prediction significance of syncope for 30-day mortality in PE patients. METHODS: A multicentric, retrospective, observational, registry-based study on consecutive PE patients was undertaken. Patients were allocated into either a men or a women group before comparisons were made between patients with syncope and those without syncope. A sex-related prediction of the significance of syncope for 30-day mortality was evaluated. RESULTS: Overall 588 patients [294 (50%) men and 294 (50%) women] were included within the study. Among men, patients with syncope were older and had significantly higher parameters of increased 30-day mortality then patients without syncope. Within the same group, however, difference in the 30-day mortality rate was not significant (log rank P = .942). In contrast to the men, fewer differences in admission characteristics were noticed among women, but those with syncope had significantly increased signs of the right ventricular dysfunction and increased 30-day mortality rate, as compared with those without syncope (log rank P = .025). After adjustment for age in a Cox regression analysis, syncope was a significant predictor of 30-day mortality in women (HR = 2.01, 95%CI 1.02-3.95). CONCLUSION: Although syncope is associated with other predictors of higher early mortality in both male and female PE patients, only in women it is a significant predictor of 30-day mortality.

BACKGROUND: Acute pulmonary embolism (PE), due to hemodynamic disturbances, may lead to multi-organ damage, including acute renal dysfunction. The aim of our study was to investigate the predictive role of renal dysfunction at admission regarding the short-term mortality and bleeding risk in hospitalized PE patients. METHODS: The retrospective cohort study included 1330 consecutive patients with PE. The glomerular filtration rate (GFR) was calculated using the serum creatinine value and Cocroft-Gault formula, at hospital admission. Primary outcomes were all-cause mortality and PE-related mortality in the 30 days following admission, as well as major bleeding events. RESULTS: Based on the estimated GFR, patients were divided into three groups: the first with GFR < 30 mL/min, the second with GFR 30-60 mL/min, and the third group with GFR > 60 mL/min. A multivariable analysis showed that GFR at admission was strongly associated with all-cause death, as well as with death due to PE. Patients in the first and second group had a significantly higher risk of 30-day all-cause mortality (HR 7.109, 95% CI 4.243-11.911, p < 0.001; HR 2.554, 95% CI 1.598-4.081, p < 0.001). Fatal bleeding was recorded in 1.6%, 0.5% and 0.8% of patients in the first, second and in the third group (p < 0.05). There were no significant differences regarding major bleeding rates among the groups. CONCLUSION: Renal dysfunction at admission in patients with acute pulmonary embolism is strongly associated with overall PE mortality.

AIMS: This study aimed to investigate whether the risk of short-term mortality is different in pulmonary embolism (PE) patients who have heart failure with reduced ejection fraction (HFrEF) as compared with those with heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: Predictive value of HFrEF or HFpEF for 7-day (intrahospital) and 30-day all-cause mortality was determined in the cohort of 1055 out of 1201 consecutive acute PE patients from the Serbian multicentre PE registry. Patients were classified into either HFrEF or HFpEF group, according to guideline-proposed criteria. A 7-day (intrahospital) and 30-day all-cause mortality was 18.5% vs. 7.3% vs. 4.5% (P < 0.001) and 22.2% vs. 16.3% vs. 7.9% (P < 0.001) for patients with the history of HFrEF, HFpEF, and without HF, respectively. Multivariable analysis adjusted to age, gender, history of chronic obstructive pulmonary disease, diabetes mellitus, arterial hypertension, presence of atrial fibrillation, and mortality risk assessment at admission has shown that only HFrEF, but not HFpEF, was an independent predictor for 7-day mortality (hazard ratio 2.22, 95% confidence interval 1.25-4,38.41, P = 0.021) and neither HFrEF or HFpEF was an independent predictor for 30-day mortality. Among various admission parameters associated to PE outcome, only systolic pressure in HFrEF patients (P < 0.001), heart rate (P = 0.01), and right ventricle systolic pressure (P = 0.039) in HFpEF patients were significantly different in patients who died compared with those who survived at 7 days. CONCLUSIONS: Our study has shown that the presence of previous history of HFrEF, but not HFpEF, in acute PE is an independent risk factor for mortality at 7 days.
RESUMO
Factors associated with provoked PE may influence a biomarker's predictive value for the primary outcome. The aim of this study was to investigate the value of BNP, cTnI, CRP and D-Dimer measurements taken soon after hospital admission for the prediction of 30-day PE-caused death in patients with spontaneous versus provoked PE.Data were extracted from a pool of 726 consecutive PE patients enrolled in the multicenter Serbian PE registry. Blood concentrations of BNP, cTnI, CRP and D-dimer were measured during the first 24â¯h of hospitalization. BNP blood level had strong predictive value for the primary outcome in spontaneous PE (c-statistics 0.943, 95% CI 0.882-1.000, pâ¯=â¯.001) and a slightly lower predictive outcome in provoked PE (c-statistics 0.824, 95% CI 0.745-0.902, pâ¯<â¯.001). NRI and IDI showed that none of the markers, when added to BNP, could improve Cox regression prediction models for 30-day PE-related mortality in either the spontaneous or provoked PE group. Blood levels of BNP measured during the first 24â¯h of hospital admission had an excellent predictive value for 30-day PE-related mortality in spontaneous PE and slightly lower predictive value in provoked PE, whereas CRP, cTnI and D-Dimer did not contribute significantly to the predictive value of BNP in either group.

OBJECTIVES: The purpose of this study was to compare the effectiveness of bucindolol with that of metoprolol succinate for the maintenance of sinus rhythm in a genetically defined heart failure (HF) population with atrial fibrillation (AF). BACKGROUND: Bucindolol is a beta-blocker whose unique pharmacologic properties provide greater benefit in HF patients with reduced ejection fraction (HFrEF) who have the beta1-adrenergic receptor (ADRB1) Arg389Arg genotype. METHODS: A total of 267 HFrEF patients with a left ventricular ejection fraction (LVEF) <0.50, symptomatic AF, and the ADRB1 Arg389Arg genotype were randomized 1:1 to receive bucindolol or metoprolol therapy and were up-titrated to target doses. The primary endpoint of AF or atrial flutter (AFL) or all-cause mortality (ACM) was evaluated by electrocardiogram (ECG) during a 24-week period. RESULTS: The hazard ratio (HR) for the primary endpoint was 1.01 (95% confidence interval [CI]: 0.71 to 1.42), but trends for bucindolol benefit were observed in several subgroups. Precision therapeutic phenotyping revealed that a differential response to bucindolol was associated with the interval of time from the initial diagnoses of AF and HF to randomization and with the onset of AF relative to that of the initial HF diagnosis. In a cohort whose first AF and HF diagnoses were <12 years prior to randomization, in which AF onset did not precede HF by more than 2 years (n = 196), the HR was 0.54 (95% CI: 0.33 to 0.87; p = 0.011). CONCLUSIONS: Pharmacogenetically guided bucindolol therapy did not reduce the recurrence of AF/AFL or ACM compared to that of metoprolol therapy in HFrEF patients, but populations were identified who merited further investigation in future phase 3 trials.

INTRODUCTION: Psychological characteristics of patients, depression, stress and anxiety are recognized as important confounding risk factors for ischemic heart disease. However, the impact of psychological characteristics on coronary ischemia and vice versa remain poorly understood. AIM: To demonstrate the interplay of psychological characteristics, depression, stress and anxiety with coronary ischemia estimated with fractional flow reserve (FFR). MATERIAL AND METHODS: From 2014 to 2016, 147 patients who were planned for FFR measurement were included in this study. Psychological characteristics of patients were evaluated using the Depression, Anxiety and Stress Scale 21 items (DASS 21) self-report questionnaire. RESULTS: Comparing the FFR ischemic vs. FFR non-ischemic groups, a significant difference was observed regarding results achieved for the depression, anxiety and stress scales. Multivariate logistic regression analysis was used to model the correlation between FFR and the DAS scale. It was clear, when controlling for previous myocardial infarction, that FFR was significant in all analyses. However, when the Canadian Cardiovascular Society grading of angina pectoris (CCS) class was entered in the model, FFR was not a significant predictor of anxiety, but was significant in other analysis. CONCLUSIONS: Higher degrees of the psychological characteristics depression, stress and anxiety were observed in the group of patients with coronary ischemia, corresponding to lower fractional flow values.
RESUMO
A 19-year-old male was admitted to our clinic with a diagnosis of suspected acute pericarditis and acute coronary syndrome. The initial diagnostics at our clinic revealed fulminant myocarditis. Twenty-four hours after admission, the patient's condition deteriorated, and he required mechanical ventilation and cardiopulmonary resuscitation. Unfortunately, the patient died. Clinical course, postmortem pathohistological findings and virus serology indicated that an H1N1 viral caused fulminant myocarditis and was the primary manifestation.

INTRODUCTION: The use of ß-blockers in the treatment of patients with coronary heart disease is associated with a decrease in the frequency of angina pectoris and mortality of patients. Due to the severity of the disease and previous cardiovascular interventions, many patients with coronary artery disease (CAD) use dual antiplatelet therapy to achieve greater inhibition of platelet aggregation. The influence of ß-blockers on platelet aggregation in patients using antiplatelet therapy is not well understood. OBJECTIVE: To examine the effect of different ß-blockers on platelet aggregation in patients on dual antiplatelet therapy. METHODOLOGY: The study included 331 patients who were treated at the Department of Cardiology, Clinical Center Kragujevac during 2011. Patients were divided into 4 groups depending on the type of ß-blockers that were used (bisoprolol, nebivolol, metoprolol, and carvedilol). Platelet aggregation was measured using the multiplate analyzer and expressed through the value of adenosine diphosphate (ADP) test (to assess the effect of clopidogrel), ASPI test (to assess the effect of acetyl salicylic acid), TRAP test (to assess baseline platelet aggregation), and the ratio of ADP/TRAP and ASPI/TRAP ASPI/TRAP (ASPI - aranchidonic acid induced aggregation, TRAP - thrombin receptor activating peptide) representing the degree of inhibition of platelet aggregation compared to the basal value. In consideration were taken the representation of demographic, clinical characteristics, laboratory parameters, and cardiovascular medications between the groups. RESULTS: Patients who used nebivolol had a significantly lower value of the ratio of ADP/TRAP (0.39 ± 0.30) compared to patients who used bisoprolol (0.48 ± 0.26; P = .038), and trend toward the lower values of ADP test (328.0 ± 197.3 vs 403.7 ± 213.2; P = .059), while there was no statistically significant difference in values of other laboratory parameters of platelet function between other groups. CONCLUSION: Patients with CAD on dual antiplatelet therapy who used nebivolol had significantly lower levels of residual ADP-induced platelet aggregation compared to baseline than patients who used bisoprolol.

One of the rarest lesions is in-stent restenosis chronic total occlusion (CTO). Limited data suggest that the treatment success rate is dependent on the possibility to cross into the lumen of an occluded stent, and the decision about what technique to use varies by operator preference. The knuckle technique is used to create a deliberate dissection plane in various CTO techniques. A guide wire is pushed until a complex loop is formed and advanced through the lesion. In this report we present a case where a knuckle wire guided by intravascular ultrasound control is used to penetrate the distal cap in an in-stent restenosis CTO lesion.
RESUMO
Coronary-subclavian steal syndrome represents a reversal of blood flow in left internal mammary artery. The most common cause of the syndrome is atherosclerotic disease in the ipsilateral, proximal subclavian artery. We present a case of 72 years old male, who developed severe anginal and neurological complaints three years after coronary artery bypass graft surgery(CABG).

INTRODUCTION: Entrapment and fracture of diagnostic or therapeutic devices within the coronary circulatory system are a rare, but increasing problem. CASE REPORT: A 70-year-old man was admitted in our clinic for coronary angiography before the planned aortic valve replacement. An arterial sheath was inserted in the right common femoral artery. After introducing a J-tip diagnostic coronary guidewire into the aorta and advancing a left Judkins diagnostic catheter over it, suddenly occured peeling off of the wire's hydrophilic coating at the aortic arch level. Very soon, this outer coating of guidewire carried by the blood stream was entered into the left femoral artery, then into the left popliteal artery. This stripped part of guidewire was successfully caught and extracted out by using a goose-neck snare catheter. CONCLUSION: A sudden stripping of outer coating of a J-tip diagnostic hydrophilic coronary guidewire during coronary angiography is possible to manage quickly and successfully by the use of a simple cathether.
