ABSTRACT
BACKGROUND: Optimal first-trimester anticoagulation is still challenging in pregnant women with mechanical heart valves (MHVs) requiring high-dose warfarin. This multicenter prospective study aims to determine the optimal anticoagulation regimens for pregnant patients with MHVs. METHODS: All women were allocated to one of three treatment options during first trimester including lone low-molecular-weight heparin (LMWH), combination of LMWH + 2.5 mg warfarin, and LMWH+4 mg warfarin. Primary maternal outcome included a combination of death, thromboembolism, severe bleeding, and need for treatment of mechanical valve thrombosis (MVT). Any fetal loss was determined as primary fetal outcome. RESULTS: The study included 78 pregnancies in 65 women with MHVs. Primary maternal outcome rate was 44%, 12.5%, 3.5%, respectively. The rates of primary maternal outcome (44 vs 3.5%, P < .001), obstructive MVT (16 vs 0%, P = .04), MVT requiring treatment (28 vs 0%, P = .003), and cerebral embolism (24 vs 3.4%, P = .041) were found to be significantly higher in lone LMWH group compared to LMWH + 4 mg warfarin group. Moreover, the rates of primary maternal outcome (12.5 vs 44%, P = .015) and treatment for MHV thrombus (4.2 vs 28%, P = .049) were significantly lower in LMWH + 2.5 mg warfarin group compared to lone LMWH group. The incidences of fetal loss were 8 (32%) in the lone LMWH group, 8 (33.3%) in LMWH + 2.5 mg warfarin group, and 11 (37.9%) in LMWH + 4 mg warfarin group (P = .890 for 3-group).Warfarin related-embryopathy was not observed in any case. CONCLUSIONS: The combined anticoagulation strategy of LMWH plus low-dose warfarin during the first trimester of pregnancy may result in less maternal complications with comparable fetal outcomes in patients with MHVs. CONDENSED ABSTRACT: Low-molecular-weight heparin (LMWH) is thought to be safer for the fetus, however it is suspected to be less protective for the mother. To solve this dilemma, the authors suggested a novel anticoagulation strategy in pregnant women with prosthetic valves. Seventy-eight pregnancies of 65 women (median age 32 [27-35] years) were included in the study. A combination of LMWH and a reduced dose warfarin were associated with low rates of thrombus-related complications in pregnant patients with mechanical heart valves.

BACKGROUND: Prosthetic valve thrombosis (PVT) is a severe and life-threatening complication. Surgery and thrombolytic therapy (TT) carry a high risk, and in several circumstances, optimal anticoagulation with unfractionated heparin (UFH) infusion may be an alternative treatment. This study aimed to assess the results of UFH in patients diagnosed with both obstructive and non-obstructive PVT. METHODS: This observational retrospective study enrolled patients who had contraindications for TT and surgery underwent UFH therapy. RESULTS: A total of 136 patients were enrolled [male: 55 (40.4%), mean age: 50.3 ± 14.6 years] in the study. In the successful group, 66 patients (48,5%) showed >75% regression in the thrombus burden without facing death or major non-fatal complications.In the unsuccessful group, 56 had less than a 50% reduction in thrombus load and 14 (10.3%) suffered major complications. The presence of obstruction (27.1% vs. 12.1%; p = 0.028), thrombus area 1.1 cm2 vs. 0.8 cm2; p = 0.005] and the duration of UFH treatment (15.1 vs. 11.8 (days); p = 0.005) were significantly higher in the unsuccessful UFH group.In multivariate regression analyses the presence of obstruction (RR: 3.088, p = 0.020), increased thrombus area (RR: 2.400; p = 0.015), and increased duration of UFH therapy (RR: 1.073 95%, p = 0.012) were identified as independent predictive parameters for a failed UFH therapy. CONCLUSIONS: This study suggests that UFH therapy may be considered a relatively beneficial treatment strategy for some patients with PVT. The most significant factors affecting success are the obstructive nature and area of the thrombus.

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common inherited disease, leading to premature atherosclerotic cardiovascular disease (ASCVD) due to elevated low-density lipoprotein cholesterol (LDL-C) levels. Achieving LDL-C goals is extremely important for preventing the complications of this fatal disease. We evaluated the management of FH patients with ASCVD in cardiology practice. METHODS: We analyzed patients with ASCVD from the nationwide EPHESUS registry, which was conducted in 40 cardiology outpatient clinics, and compared those with and without FH. RESULTS: Of the 1482 consecutively enrolled patients with ASCVD, 618 (41.7%) had FH, among which 455 were categorized as 'Possible FH' and 163 as 'Probable or Definite FH'. Proposed LDL-C goals were not attained in more than 90% of the patients with FH. The proportion of those on statin therapy was 77% for possible and 91% for probable or definite FH, whereas 34.2 % and 59.4% were in use of high-intensity statins, respectively. None of the patients were on PCSK-9 inhibitors, and only 2 used ezetimibe. Adverse media coverage was the most common cause of statin discontinuation (32.5% in 'possible FH' and 45.7% in 'probable/definite FH'). The negative impact of media in the decision to stop lipid lowering therapy (LLT) was increasing with education level. CONCLUSIONS: In real life most of the FH patients with ASCVD are undertreated in cardiology practice regarding statin dosing and combined LLT. Drug discontinuation rates are notably high and are mostly media-related, and side effects very rarely cause cessation of LLT. Urgent measures are needed to increase the awareness of FH among healthcare providers and patients and to develop improved treatment strategies aimed at preventing the complications of FH.

OBJECTIVE: This study aimed to describe the eï¬ects of new academic criteria established in 2016 on the abstracts of the National Congress of the Turkish Society of Cardiology. METHODS: The abstracts presented at 13 consecutive annual congresses were obtained. A literature search was conducted with PubMed, Google Scholar, and Web of Science databases to analyze whether the abstract was published in a scientiï¬c journal. The study was divided into 2 time groups according to the new academic criteria published in 2016. Group 1 included 4828 abstracts accepted at National Congress of the Turkish Society of Cardiology between 2009 and 2016, while Group 2 included 2284 abstracts accepted at National Congress of the Turkish Society of Cardiology between 2017 and 2021. RESULTS: A total of 7112 abstracts were accepted for the 2009-2021 National Congress of the Turkish Society of Cardiology meetings scientiï¬c program. The publication rate (43.2% vs. 23.9%, P < 0.001), number of authors [7(5-9) vs. 4(3-6), P < 0.001], and rate of original investigation (72.3 vs. 56.5%, P < 0.001) were signiï¬cantly lower in group 2 than in group 1. Among the quality parameters of the journals in which the abstracts were published, the impact factor (0.59 ± 1.71 vs. 0.26 ± 1.09, P < 0.001), the rate of journals in science citation index or science citation index-expanded indexes (70.4 vs. 57.9%, P < 0.001), and the rate of the second or third-quartile class (24.2 vs. 16.1%, P < 0.001) were signiï¬cantly lower in group 2 as compared to group 1. Being in group 1 oral presentation, original investigation, and cardiac imaging were identiï¬ed as independent predictors for publication in scientiï¬c journals. CONCLUSION: This study showed that the 2016 new academic criteria negatively aï¬ected the publication processes of accepted abstracts in National Congress of the Turkish Society of Cardiology.
ABSTRACT
BACKGROUND: The recent 2019 European Society of Cardiology/European Atherosclerosis Society practice guidelines introduced a new risk categorization for patients with diabetes. We aimed to compare the implications of the 2016 and 2019 European Society of Cardiology/European Atherosclerosis Society guidelines with regard to the lipid-lowering treatment use, low-density lipoprotein cholesterol goal attainment rates, and the estimated proportion of patients who would be at goal in an ideal setting. METHODS: Patients with diabetes were classified into 4 risk categories according to 2019 European Society of Cardiology/European Atherosclerosis Society dyslipidemia guidelines from the database of EPHESUS (cross-sectional, observational, countrywide registry of cardiology outpatient clinics) study. The use of lipid-lowering treatment and low-density lipoprotein cholesterol goal attainment rates were then compared according to previous and new guidelines. RESULTS: This analysis included a total of 873 diabetic adults. Half of the study population (53.8%) were on lipid-lowering treatment and almost one-fifth (19.1%) were on high-intensity statins. While low-density lipoprotein cholesterol goal was achieved in 19.5% and 7.5% of patients, 87.4% and 69.6% would be on target if their lipid-lowering treatment was intensified according to 2016 and 2019 European Society of Cardiology/European Atherosclerosis Society lipid guidelines, respectively. The new target <55 mg/dL could only be achieved in 2.2% and 8.1% of very high-risk primary prevention and secondary prevention patients, respectively. CONCLUSION: The control of dyslipidemia was extremely poor among patients with diabetes. The use of lipid-lowering treatment was not at the desired level, and high-intensity lipid-lowering treatment use was even lower. Our simulation model showed that the high-dose statin plus ezetimibe therapy would improve goal attainment; however, it would not be possible to get goals with this treatment in more than one-third of the patients.

BACKGROUND: A subset ofpatients found to have total occlusion of the culprit artery (TOCA), present with non-ST-segment elevation myocardial infarction (NSTEMI) and elevated biomarkers. The aim of this study is to assess the effect of the TOCA in patients presenting with NSTEMI. METHODS: This multicenter observational study was retrospectively conducted between 2015 and 2019. Thrombolysis in myocardial infarction (TIMI) flow grades 0-1 was defined as the TOCA. The primary end point included a combination of all-cause death, myocardial infarction, target vessel revascularization, stent thrombosis, and stroke. RESULTS: Of 3272 patients, TIMI 0-1 flow in the culprit artery was present in 488 (14.9%) patients. TOCA was more likely to be of thrombotic origin (54.1% vs. 10.3%; P < 0.001) and visible collaterals (22.5% vs. 4.4%; P < 0.001). The rates of 30-day (14.3% vs. 7.2%; P < 0.001) and 2-year (25% vs. 19.1%; P = 0.003) primary end points were significantly higher in TOCA patients. Fatal arrhythmias were remarkably higher at 30-day (8.6% vs. 4%; P < 0.001) and 2-year (9% vs. 5.2%; P = 0.001) follow-ups. Mechanical complications were also higher in patients with TOCA at 30 days (0.8% vs. 0.2%; P = 0.013). Moreover, TOCA (OR, 1.379; P = 0.001) was one of the independent predictors of MACCE in NSTEMI patients. CONCLUSION: The current data suggest that patients with TOCA in the context of NSTEMI are at higher risk of MACCE, fatal arrhythmias, and mechanical complications.

BACKGROUND: The effect of physiological circulatory changes during pregnancy on hypertrophic cardiomyopathy (HCM) has been reported with limited data. This study aimed to provide information regarding outcomes of pregnant women with HCM and to identify predictors of major adverse cardiac event (MACE). METHODS: A total of 45 pregnancies with HCM were retrospectively reviewed. The primary endpoint was a MACE that occurred within an 8week period after delivery, including maternal death, heart failure (HF), syncope, and malignant ventricular arrhythmias (VAs). Baseline and outcome data were analyzed for all patients. Patients with and without MACE were compared, and patients with obstructive HCM were compared with those who had non-obstructive HCM. The study population was divided into two subgroups of patients having or not having an implantable cardioverter defibrillator implantation (ICD). RESULTS: At least one MACE occurred in 11 patients (24.4%); six patients developed HF (13.3%), six had a ventricular tachyarrhythmia (13.3%), and two had syncope (4.4%). New York Heart Association functional class of ≥â¯II, presence of HF signs before pregnancy, increased left ventricular outflow tract (LVOT) gradient were significantly associated with MACE. Fatal VAs were seen during pregnancy in one of five HCM patients with ICD. In the ROC curve analysis, an LVOT gradient higher than 53.5â¯mmâ¯Hg predicted the presence of MACE with a sensitivity of 90.9% and a specificity of 73.5%. This study is the largest series in the literature representing pregnant women who had HCM and ICD. CONCLUSION: The current data suggest that HF and high LVOT gradients are important risk factors for the development of cardiac complications.

This study aimed to evaluate the relationship between no-reflow phenomenon and systemic inflammation index (SII) and to compare the predictive capacity of SII together with the neutrophil-lymphocyte ratio (NLR), and the platelet-lymphocyte ratio (PLR) in patients with ST-elevation myocardial infarction (STEMI). A total of 785 patients were included. The thrombolysis in myocardial infarction (TIMI) flow degree has been used to describe the no-reflow phenomenon. The study population was divided into two groups regarding the presence of no-reflow phenomenon including 110 patients with no-reflow (TIMI frame count 0-2) and 675 patients without no-reflow (TIMI frame count 3). The NLR [6.6 (4.6-11.6) vs 3.2 (2.0-5.3); P < .001], PLR [175 (121.3-220) vs 102.6 (76.1-150.1); P < .001] and SII [1921(1225-2906) vs 738.5 (450.5-1293); P < .001] were significantly higher in the no-reflow group. High NLR (OR: 1.078, 95%CI: 1.027-1.397; P = .021), PLR (OR: 1.009, 95%CI: 1.003-1.021; P = .041) and SII (OR: 1.216, 95%CI: 1.106-1.942; P = .004) were found to be independently associated with no-reflow phenomenon. The comparison of the receiver-operating characteristic curves showed that area under the curve of SII was greater than that of NLR (.789 vs .766, P = .007) and PLR (.789 vs .759, P = .048). SII levels may predict no-reflow phenomenon better than NLR and PLR.

BACKGROUND: Left ventricular apical thrombus (LVAT) formation is a well-known complication of acute anterior myocardial infarction (AMI). The CHA2DS2VASc is a scoring system that has been used to estimate the risk of thromboembolism in patients with nonvalvular atrial fibrillation. This score has also been used for other clinical conditions. The aim of this study was to investigate the relationship between CHA2DS2VASc score and development of LVAT in patients with AMI. METHOD: The study population included 378 patients (mean age: 56.5 ± 12.3 years, male: 318) presenting with AMI between January 2016 and January 2020. Primary percutaneous coronary intervention procedure was performed in all patients. Initial echocardiogram was performed within 7 days of admission. All patients were evaluated with echocardiography at 3rd, 6th and 12th months. Patients were divided into two groups according to the presence of LVAT on echocardiography. RESULTS: The incidence of the LVAT was 8.5% (n = 32) during a mean follow-up time of 233.1 ± 66.7 days. The mean CHA2DS2VASc score was notably higher in patients with LVAT compared to patients in the control group (3.1 ± 1.9 vs. 1.9 ± 1.2, p < 0.001). In Cox regression analysis, high CHA2DS2VASc score, low left ventricular ejection fraction (LVEF) and the presence of LV apical akinesis/aneurysm were the independent predictors for LVAT formation. All of these parameters were associated with higher cumulative incidence of LVAT formation in Kaplan-Meier analyses (p < 0.001 for all). CONCLUSION: High CHA2DS2VASc score, low LVEF and the presence of LV apical akinesis/aneurysm may be used for LVAT risk prediction among patients presenting with AMI.

AIM: This study aimed to evaluate the relationship between intracoronary thrombus burden and systemic immune-inflammation index (SII) and to compare the predictive capacity of SII together with the neutrophil-lymphocyte ratio (NLR), and the platelet-lymphocyte ratio (PLR) in patients with ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI). PATIENT & METHODS: A total of 425 patients were included in the study. The clinical, laboratory, and demographic characteristics of the patients were recorded. The thrombus classification "Thrombolysis in myocardial infarction (TIMI)" was used to assess the intracoronary thrombus burden. According to the TIMI thrombus classification, 229 (54%) patients with low thrombus burden (grade 0-3) and 196 (46%) patients with high thrombus burden (grade 4 and 5) were compared. SII was calculated as platelet × neutrophil/lymphocyte counts. RESULTS: High NLR (OR: 1.068, 95% CI:1.023-1.404; p = 0.031), PLR(OR: 1.012, 95% CI:1.002-1.018; p = 0.043), SII(OR: 1.325, 95% CI: 1.156-1.879; p = 0.015) and low left ventricle ejection fraction (LVEF) (OR: 0.957, 95% CI:0.924-0.990; p = 0.012) were found to be independent predictors of high thrombus burden. SII values above 812 predicted a high thrombus burden with a sensitivity of 82% and specificity of 73% (AUC: 0.836; 95% CI:0.795-0.877; p < 0.001). This predictiveness of SII was stronger as compared to NLR (0.836 vs. 0.818, p = 0.043) and PLR (0.836 vs. 0.780, p < 0.001). CONCLUSION: SII is an independent predictor of high thrombus burden in patients with STEMI. In addition, SII is superior to NLR and PLR in this regard.

BACKGROUND: Intermittent malfunction is a rare but potentially serious complication of prosthetic heart valve replacement. This study aimed to describe the clinical features and etiologic causes of patients with intermittent mechanical prosthetic heart valve dysfunction. METHODS: Between 2010 and 2021, 16 patients who were evaluated in the echocardiography laboratory of Kosuyolu Training and Research Hospital with the diagnosis of intermittent malfunction of prosthetic valves were included in the study. RESULTS: The evaluated patients consisted of 12 bi-leaflet mitral valve replacements and 2 mono-leaflet mitral valve replacements. The underlying causes of intermittent malfunction were classified as follows: residual chord (n=4), obstructive thrombus (n=2), non-obstructive thrombus (n=2), vegetation (n=2), pannus and obstructive thrombus coexistence (n=1), and solely pannus (n=1). One of the patients with mono-leaflet mitral valve replacements had pannus and obstructive thrombus. In the other patient with mono-leaflet mitral valve replacement, a stuck valve was observed in 1 of 12 beats secondary to arrhythmia. There were also 2 patients with aortic valve replacements. One patient had moderate aortic regurgitation due to prominent calcification and the other had moderate obstruction due to pannus. In the patient with pannus, a stuck leaflet was observed in 1 of 6 beats and moderate aortic regurgitation arose in 1 of 2 beats in the patient with calcification. CONCLUSIONS: The intermittent stuck valve may have catastrophic outcomes. When making a treatment decision in these patients, assessing the degree of regurgitation or stenosis is essential. In particular, the frequency of entrapment should be taken into consideration when deciding the optimal therapy for intermittent prosthetic heart valve dysfunction.

Paravalvular leak (PVL) is a complication of valve replacement surgery which may lead to serious clinical consequences including hemolytic anemia. This study aimed to retrospectively evaluate the effect of successful intervention on serum lipid parameters in patients with PVL. A total of 106 patients (mean age: 57.2 ± 13.6 years, male: 67) who underwent surgical or transcatheter closure for symptomatic PVL were enrolled in this study. During the follow-up period, hemolysis and lipid parameters were evaluated at each clinical visit. This is the first study describing the effects of PVL on lipid metabolism after surgical or transcatheter closure. In the study, 18 patients (17%) had aortic PVL, 84 patients (79%) had mitral PVL, and 4 patients (3.8%) had both aortic and mitral PVL. A total of 59 patients underwent transcatheter closure and 47 patients were treated surgically. Technical success of the procedures was 83%. After successful PVL closure, hemoglobin and haptoglobin levels increased significantly (9.5 ± 1.3 vs 11.9 ± 2.1 g/dl, p <0.001 and 16.6 ± 7.9 vs 34.1 ± 19.9 mg, p <0.001, respectively). A significant increase in total cholesterol (158.9 ± 42.7 vs 209.3 ± 58.7 mg/dl, p <0.001), low-density lipoprotein cholesterol (99.1 ± 33.8 vs 133.9 ± 45.7 mg/dl, p <0.001), and high-density lipoprotein cholesterol (39.8 ± 12.4 vs 44.8 ± 11.7 mg/dl, p <0.001) levels was observed after successful PVL closure. In conclusion, symptomatic patients with PVL had hypocholesterolemia, reflected by low serum lipoprotein levels. After successful PVL closure, an increase in serum lipoprotein levels was observed. The recovery in levels of lipoproteins could be used as a marker of successful PVL closure, and absence of recovery of lipoprotein levels may indicate incomplete closure.

BACKGROUND: Prosthetic valve thrombosis (PVT) is one of the life-threatening complications of prosthetic heart valve replacement. Due to the lack of randomized controlled trials, the optimal treatment of PVT remains controversial between thrombolytic therapy (TT) and surgery. OBJECTIVES: This study aimed to prospectively evaluate the outcomes of TT and surgery as the first-line treatment strategy in patients with obstructive PVT. METHODS: A total of 158 obstructive PVT patients (women: 103 [65.2%]; median age 49 years [IQR: 39-60 years]) were enrolled in this multicenter observational prospective study. TT was performed using slow (6 hours) and/or ultraslow (25 hours) infusion of low-dose tissue plasminogen activator (t-PA) (25 mg) mostly in repeated sessions. The primary endpoint of the study was 3-month mortality following TT or surgery. RESULTS: The initial management strategy was TT in 83 (52.5%) patients and surgery in 75 (47.5%) cases. The success rate of TT was 90.4% with a median t-PA dose of 59 mg (IQR: 37.5-100 mg). The incidences of outcomes in surgery and TT groups were as follows: minor complications (29 [38.7%] and 7 [8.4%], respectively), major complications (31 [41.3%] and 5 [6%], respectively), and the 3-month mortality rate (14 [18.7%] and 2 [2.4%], respectively). CONCLUSIONS: Low-dose and slow/ultraslow infusion of t-PA were associated with low complications and mortality and high success rates and should be considered as a viable treatment in patients with obstructive PVT.

BACKGROUND: Carotid artery stenting is a minimally invasive, durable alternative treatment option, which is an alternative to the reference method, carotid endarterectomy, for patients with carotid artery stenosis; however, silent new ischemic cerebral lesions (SNICLs) after carotid artery stenting remain as a matter of concern. Hence, we aimed to assess the effect of complex vascular anatomy on silent new ischemic cerebral lesions in carotid artery stenting procedures. METHODS: We prospectively evaluated 122 patients (mean age: 69.5 ± 7.1 years, male:83) who underwent carotid artery stenting for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after carotid artery stenting were excluded. The presence of a new hyperintense lesions on diffusion-weighted imaging without any neurological findings was considered as the SNICL. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among the study population, 32 patients (26.2%) had SNICLs. The DWI-positive group had a significantly higher common carotid artery (CCA)-internal carotid artery (ICA) angle, older age, more frequent history of stroke, a higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. High CCA-ICA angle was identified as one of the independent predictors of SNICL (OR (odds ratio) = 1.103 95%CI (confidence interval): (1.023-1.596); p = 0.034), and CCA-ICA angle higher than 34.5 degrees predicted SNICL with a sensitivity of 62.5% and a specificity of 62.2% (area under the curve: 0.680; 95% CI: 0.570 to 0.789; p = 0.003). CONCLUSIONS: The higher CCA-ICA angle may predict pre-procedure SNICL risk in carotid artery stenting and may have clinical value in the management of patients with carotid artery stenosis.

BACKGROUND: Congenital coronary artery anomalies (CCAAs) have the potential for life-threatening complications, including malignant ventricular arrhythmias and sudden cardiac death (SCD). In this study, we aimed to evaluate the relationship between impaired repolarization parameters and poor cardiovascular clinical outcomes in patients with potentially serious CCAAs. METHODS: This retrospective study included 85 potentially serious CCAA patients (mean age: 54.7 ± 13.6 years; male:44) who were diagnosed with conventional and coronary computed tomography angiography (CCTA). All patients underwent transthoracic echocardiography and 12-lead surface electrocardiography. Cardiac events were defined as sustained ventricular tachycardia or fibrillation, syncope, cardiac arrest and SCD. RESULTS: The presence of interarterial course (IAC) was confirmed by CCTA in 37 (43.5%) patients. During a median follow-up time of 24 (18-50) months, a total of 11 (12.9%) patients experienced cardiac events. The presence of IAC was significantly more frequent and Tp-e interval, Tp-e/QTc ratio and frontal QRS/T angle (fQRSTa) were significantly greater in patients with poor clinical outcomes. Moreover, the presence of IAC, high Tp-e/QTc ratio and high fQRSTa were found to be independent predictors of poor clinical outcomes and decreased long-term cardiac event-free survival in these patients. A net reclassification index was +1.0 for the Tp-e/QTc ratio and +1.3 for fQRSTa which were confirmable for additional predictability of these repolarization abnormalities. CONCLUSION: Impaired repolarization parameters, including wider fQRSTa, prolonged Tp-e interval, and increased Tp-e/QTc ratio, and IAC may be associated with poor cardiovascular clinical outcomes in potentially serious CCAA patients.

OBJECTIVE: Infective endocarditis (IE)-related ST elevation myocardial infarction (STEMI) is extremely rare. A clear clinical consensus is lacking regarding the management of this emergency. In this study, we aimed to describe the clinical outcomes of treatment strategies in this patient population. METHODS: The study population comprised 19 retrospectively evaluated patients (nine women; mean age 52±11.8 years) with a diagnosis of IE-related STEMI. Transesophageal echocardiography detected vegetation in all the patients. The study population was divided into two groups on the basis of in-hospital mortality. RESULTS: Major clinical manifestations included dyspnea (89.5%), fever (78.9%), and chest pain (63.2%). Catheter-based coronary angiography was performed in all the patients. The causative agent was isolated in all the cases, and Staphylococcus aureus was identified in seven (36.8%). The most common infarction was in the left anterior descending artery (n=12 [63.2%]). The treatment strategy consisted of mechanical thrombectomy (n=1), valve replacement following stent implantation (n=5), direct balloon angioplasty (n=4), valve replacement along with coronary artery bypass grafting (CABG; n=6), and medical follow-up (n=3). Moreover, thrombolysis in myocardial infarction III flow was significantly higher in the survival group (100% vs. 0%, p<0.001). All these patients preferred CABG or stent implantation for revascularization. CONCLUSION: The current data suggest that a revascularization strategy with stent implantation or revascularization with CABG has a lower mortality rate in patients with IE-related STEMI.
