ABSTRACT
OBJECTIVE: Electrocardiographic left ventricular hypertrophy (ECG LVH) holds significant clinical importance in cardiovascular disease. Pathological processes that lead to left ventricular hypertrophy (LVH) also induce remodeling and impair left atrial (LA) function. Atrial function can be assessed using speckle-tracking echocardiography. This study investigates the potential impact of ECG LVH on LA strain. METHODS: A total of 62 individuals diagnosed with LVH, based on the echocardiographic left ventricular mass index, were included. ECG LVH was assessed using established protocols: the Sokolow-Lyon voltage criteria (SV1 + RV5/RV6 > 35 mm), Cornell voltage criteria (RaVL + SV3 > 28 mm for men and > 20 mm for women), and the Cornell product criteria [(SV3 + RaVL + (for women 8 mm)] x QRS duration > 2440 mm x ms). Participants were categorized into two groups based on the presence or absence of ECG LVH. The relationship between LA strain measures and ECG characteristics was explored. RESULTS: The study population had a median age of 58.3 ± 10.1 years, with 40.3% being female, 91.9% hypertensive, and 35.5% diabetic. Nineteen patients (30.6%) were identified with ECG LVH based on Sokolow-Lyon voltage, Cornell voltage, or Cornell product criteria. These patients exhibited significantly reduced LA reservoir, conduit, and contraction strains (P < 0.001). Statistically significant correlations were observed between all three phases of LA strain measures and Sokolow-Lyon voltage (reservoir r = -0.389, P < 0.01; conduit r = -0.273, P < 0.05; contraction r = -0.359, P < 0.01), Cornell voltage (reservoir r = -0.49, P < 0.001; conduit r = -0.432, P < 0.001; contraction r = -0.339, P < 0.01), and Cornell product (reservoir r = -0.471, P < 0.001; conduit r = -0.387, P < 0.01; contraction r = -0.362, P < 0.01). CONCLUSION: ECG LVH is associated with impaired LA strain, validating its use as an effective tool for predicting LA dysfunction.

BACKGROUND: The prognosis of hypertrophic cardiomyopathy (HCM) varies from mild disease with a normal life expectancy to heart failure and sudden cardiac death (SCD). The identification of patients who are at high risk for SCD remains challenging. AIMS: In this study, we evaluated the prognostic value of papillary muscle-free strain in HCM patients. METHODS AND RESULTS: Seventy-nine patients with a diagnosis of HCM were included in this study. Patients were divided into low/intermediate-risk (n = 57) and high-risk (n = 22) groups. Two-dimensional (2-D) echocardiography and strain imaging were performed for each patient. The mean age of the study population was 53.85 ± 15.88 years; 47 (59.5%) of them were male. During a mean follow-up duration of 74.45 ± 17.03 months, 12 patients died. A comparison of the low-intermediate and high-SCD risk groups revealed that patients in the high-SCD risk group had greater maximal wall thickness, interventricular septum thickness, posterior wall thickness, and left ventricular mass index (LVMI) and lower (less negative) global longitudinal, anterolateral papillary muscle (ALPM) and posteromedial papillary muscle (PMPM) free strain. Additionally, a history of syncope and ICD implantation were found to be more common in patients with high SCD risk scores. The SCD risk score was positively correlated with the global longitudinal strain, ALPM-free strain, and PMPM-free strain (r = .528, r = .658, and r = .600, respectively; p < .001 for all). Our results showed that the LVMI, presence of syncope, global longitudinal strain, and ALPM-free strain were predictors of death. CONCLUSIONS: Decreased papillary muscle-free strain values might have prognostic value in patients with HCM.

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.

OBJECTIVE: Sleep quality in those with cardiovascular disease is significantly lower than in the general population. This study aimed to explore the effect of transcatheter or surgical closure of atrial septal defect (ASD) on sleep quality. METHODS: One hundred nineteen adult patients with ASD who underwent transcatheter or surgical closure were included in the study. Sleep quality was investigated prospectively just before defect closure and six months after defect closure. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality of these patients. RESULTS: PSQI scores were similar in both groups before the procedure in patients who underwent both transcatheter and surgical closure. The PSQI scores six months after transcatheter closure was significantly improved compared to the PSQI score before transcatheter ASD closure (3.5 ± 2.0 vs. 6.9 ± 3.4, respectively; P<0.001). The PSQI scores six months after surgical ASD closure was significantly improved compared to the PSQI score before surgical closure (4.8 ± 2.1 vs. 7.1 ± 2.0, respectively; P<0.001). Total PSQI scores were also statistically different at six months after transcatheter and surgical closure (3.5 ± 2.0 vs. 4.8 ± 2.1, P=0.014). However, six months after both transcatheter and surgical closure, PSQI scores were significantly decreased in both groups which was more pronounced in patients who underwent transcatheter closure. CONCLUSION: Transcatheter or surgical closure of the defect may be beneficial in improving the sleep quality of adult patients with ASD. Delayed improvement of sleep quality after surgical closure may be an important advantage for transcatheter closure.

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: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

Conclusion: Transcatheter or surgical closure of the defect may be beneficial in improving the sleep quality of adult patients with ASD. Delayed improvement of sleep quality after surgical closure may be an important advantage for transcatheter closure.
ABSTRACT
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
Increased inflammatory biomarkers have been reported in prosthetic heart valve thrombosis (PHVT). Monocyte to HDL ratio (MHR) and albumin to CRP levels (CAR) are two biomarkers used widely for systemic inflammation but there is a lack of data on prosthetic heart valves. This study aimed to find out the potential predictive value of MHR and CAR for PHVT. Patients who had the diagnosis of mechanical mitral/aortic PHVT and normally functioning prosthesis were retrospectively analyzed. Laboratory data including complete blood count and biochemistry were recorded. Transesophageal echocardiography was performed to diagnose PHVT. The study included 118 patients with mechanical PHVT and 120 patients with normally functioning prosthesis. White blood count, monocyte levels, C-reactive protein, MHR and CAR were significantly higher whereas the lymphocyte, HDL and INR levels on admission were lower in patients with PHVT. Multivariate analysis showed that as well as inadequate anticoagulation, MHR, but not CAR, was found to be an independent predictor of thrombosis in patients with PHVT. Receiver operating characteristic curve analysis was performed to detect the best cut-off value of MHR in the prediction of thrombosis in patients with prosthetic valves. MHR level of > 12.8 measured on admission, yielded an AUC value of 0.791 [(CI 95% 0.733-0.848 p < 0.001) sensitivity 71%, specificity 70%]. Inadequate anticoagulation is the primary cause that leads to thrombosis in mechanical prosthetic valves. Increased MHR, but not CAR, was also shown to be an independent predictor of thrombosis in patients with mechanical mitral and aortic prosthetic valves.
ABSTRACT
OBJECTIVES: We aimed to evaluate and compare papillary muscle free strain in hypertrophic cardiomyopathy (HCMP) and hypertensive (HT) patients. METHODS: Global longitudinal strain (GLS), and longitudinal myocardial strain of the anterolateral (ALPM) and posteromedial papillary muscles (PMPM) were obtained in 46 HCMP and 50 HT patients. RESULTS: Interventricular septum (IVS)/posterior wall (PW) thickness ratio, left ventricular mass index (LVMI), left atrial anteroposterior diameter (LAAP) and mitral E/E' were found to be increased in patients with HCMP compared to HT patients. Left ventricular cavity dimensions were smaller in HCMP patients. GLS of HCMP and HT patients were - 14.52 ± 3.01 and -16.85 ± 1.36%, respectively (p < 0.001). Likewise, ALPM and PMPM free strain values were significantly reduced in HCMP patients over HT patients [-14.00% (-22 to -11%) and -15.5% (-24.02 to -10.16%) vs -23.00% (-24.99 to -19.01%) and -22.30% (-26.48 to -15.95%) (p = 0.016 and p = 0.010)], respectively. ALPM free strain showed a statistically significant correlation with GLS, maximal wall thickness, IVS thickness and LVMI. PMPM free strain showed a significant correlation with GLS, IVS thickness and LAAP. The GLS value of - 13.05 had a sensitivity of 61.9% and a specificity of 97.4% for predicting HCMP. ALPM and PMPM free strain values of -15.31 and -17.17% had 63 and 76.9% sensitivity and 85.7 and 76.9% specificity for prediction of HCMP. CONCLUSIONS: Besides other echocardiographic variables, which were investigated in earlier studies, papillary muscle free strain also could be used in HCMP to distinguish HCMP- from HT-associated hypertrophy.

BACKGROUND: It has been shown that the increase in volume and pressure in the right heart chambers increases liver stiffness. The Albumin-Bilirubin (ALBI) score is a useful and easy-to-use score for objectively assessing liver function. There is no information in the literature about changes in ALBI score in patients with atrial septal defect (ASD). The aim of our study is to investigate the changes in ALBI score and its clinical impact in patients with ASD. METHODS: Of the 206 analyzed patients, 77 were excluded. The remaining 129 patients with secundum type ASD with left to right shunt were divided into three groups; Group I (16 patients with Qp/Qs < 1.5 and defect diameter < 10 mm), Group II (52 patients with Qp/Qs > 1.5 and defect diameter 10-20 mm) and Group III (61 patients with Qp/Qs > 1.5 and defect diameter > 20 mm). The ALBI score was calculated based on serum albumin and total bilirubin levels using the following formula: ALBI = (log10 bilirubin [umol/L] * .66) + (albumin [g/L] * -.085). RESULTS: ALBI scores as well as total bilirubin levels, transaminases, and functional-structural heart abnormalities (increase in RA and RV dimensions, sPAP, ASD size and decrease in LVEF and TAPSE) showed a significant increasing trend from Group I to Group III (p < .001 for all comparisons). The mean ALBI scores for Group I, Group II, and Group III were -3.71 ± .37, -3.51 ± .25, and -3.27 ± .34, respectively. In multivariate linear regression analysis, ASD size, sPAP, RV-RA diameter were found to be significantly associated with increased ALBI score. CONCLUSION: The ALBI score offers a simple, evidence-based, objective, and discriminatory method of assessing liver function in patients with ASD. ASD size, sPAP, RV and RA diameters were significantly associated with ALBI score.

Patent foramen ovale closure is recommended for patients who are at risk for recurrent paradoxical embolism and cryptogenic stroke. The standard technique of patent foramen ovale closure is established from the femoral vein. However, alternative methods may be necessary for patent foramen ovale closure as in every interventional procedure. A 45-year-old female patient with an intramural giant uterine myoma had a history of recurrent deep vein thrombosis and stroke. A diffuse thrombus was detected in both iliac veins associated with inferior vena cava compression of the myoma. Also, a patent foramen ovale was revealed on echocardiography as a cause of embolic events. Hysterectomy was initially planned by gynaecology, but due to the possible risk of embolisation of inferior vena cava thrombus and stroke after removal of the compressive mass during hysterectomy, initial patent foramen ovale closure and then hysterectomy was scheduled in the Gynecology-Cardiology-Cardivascular Surgery council. Patent foramen ovale closure was performed via the right jugular vein approach. But because of the tight left atrial ostium of the patent foramen ovale, the catheter could not pass to the left atrium from the right atrium. With an anchor of a 5.0 × 15 mm coronary balloon over a 0.014-inch guidewire to the pulmonary vein, we were able to reach the left atrium. The patent foramen ovale was closed successfully, and the patient underwent a hysterectomy after closure without any embolic event. The patient was asymptomatic at 6 months of control.

BACKGROUND: Papillary muscle free strain has not been evaluated previously in hypertrophic cardiomyopathy (HCMP) patients. Our aim was to evaluate free papillary muscle free strain in HCMP patients and to find whether it has a value for prediction of sudden cardiac death (SCD) risk score. METHODS: Transthoracic echocardiography with tissue Doppler imaging, 2-D speckle tracking imaging (STI) of 55 HCMP patients and 45 controls were performed. HCMP patients were further divided into two groups according to their SCD risk score. Patients with risk score of less than 6 points constituted low/intermediate risk group, whereas patients with risk score of greater or equal to 6 points constituted high risk group. RESULTS: Interventricular septum, posterior wall, and left ventricular mass index were significantly higher, whereas mitral E/A ratio was significantly lower in HCMP patients compared to controls. Longitudinal apical 4C, 2C, 3C, global longitudinal LV strain, anterolateral papillary muscle (ALPM), posteromedial papillary muscle (PMPM) free strain were significantly reduced in HCMP group compared to control group. Global longitudinal strain and ALPM free strain were significantly lower in patients with high SCD risk score (-14.6 (-17.4 - -13.1) vs -11.6 (-13.2 - -10.1), p = 0.001 and -17.1 (-20.3 - -14.0) vs -9.2 (-12.6 - -7.5), p<0.001, respectively. Global longitudinal strain and ALPM free strain were statistically significantly correlated with SCD risk score (r = 0.480, p<0.001 and r = 0.462, p<0.001, respectively). Global longitudinal strain value of -12.60% had a sensitivity of 73.3% and specificity of 82.5% for predicting high SCD risk score (AUC: 0.787, 95% CI: 00.643-0.930, p = 0.001). ALPM free strain value of -12.95% had 66.7% sensitivity and 77.5% specificity for predicting high SCD risk score (AUC: 0.766, 95% CI: 0.626-0.905, p = 0.003). CONCLUSION: Papillary muscle free strain was reduced in HCMP patients. It might be used in risk stratification of these 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.

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.

OBJECTIVE: This study examines the predictive value of the novel systemic immune-inflammation index (SII) in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 1660 patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) were enrolled in the study. In-hospital and 3-year outcomes were compared between the four groups (Q1-4). The SII was calculated using the following formula: neutrophil*platelet/lymphocyte. RESULTS: The frequency of in-hospital cardiogenic shock, acute respiratory failure, acute kidney injury, ventricular arrhythmia, stent thrombosis, recurrent myocardial infarction, major adverse cardiac events and mortality were significantly higher in the high SII groups (Q3 and Q4). Logistic regression models demonstrated that Q3 and Q4 had an independent risk of mortality and Q4 had an independent risk of cardiogenic shock compared to Q1. Receiver operating characteristic analysis showed that the best cutoff value of SII to predict the in-hospital mortality was 1781 with 66% sensitivity and 74% specificity. Kaplan-Meier overall survivals for Q1, Q2, Q3 and Q4 were 97.6, 96.9, 91.6 and 81.0%, respectively. Cox proportional analysis for 3-year mortality demonstrated that Q3 and Q4 had an independent risk for mortality compared to Q1. CONCLUSION: SII, a novel inflammatory index, was found to be a better predictor for in-hospital and long-term outcomes than traditional risk factors in patients with STEMI undergoing pPCI.
