Systemic immune inflammation index and its implication on in-stent restenosis among patients with acute coronary syndrome.

OBJECTIVE: This study aims to assess the predictive value of the Systemic Immune Inflammation Index (SII) in determining in-stent restenosis (ISR) likelihood in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI). METHODS: The study enrolled 903 ACS patients undergoing PCI, categorized into ISR (+) and ISR (-) groups based on control coronary angiography results. Demographic, clinical, laboratory, and angiographic-procedural characteristics were systematically compared. RESULTS: The ISR (+) group encompassed 264 individuals (29.2%), while the ISR (-) group comprised 639 individuals (70.8%). Patients had a mean age of 55.8 ±â€…10.2 years, with 69% being male. The ISR (+) group had higher diabetes and smoking prevalence and notably larger stent dimensions. Lab parameters showed significantly elevated creatinine, total cholesterol, red cell distribution width, white blood cell and neutrophil counts, SII index and C-reactive protein (CRP) in the ISR (+) group, while lymphocyte levels were lower. Binary logistic regression identified stent diameter (odds ratio [OR]: 0.598, 95% confidence interval [CI]: 0.383-0.935; P  = 0.024), stent length (OR: 1.166, 95% CI: 1.132-1.200; P  < 0.001), creatinine (OR: 0.366, 95% CI: 0.166-0.771; P  = 0.003), CRP (OR: 1.075, 95% CI: 1.042-1.110; P  = 0.031), and SII index (OR: 1.014, 95% CI: 1.001-1.023; P  < 0.001) as independent ISR predictors. CONCLUSION: The SII index exhibits potential as a predictive marker for ISR in ACS patients post-PCI, indicating systemic inflammation and heightened restenosis risk. Integrating the SII index into risk models could identify high-risk patients for targeted interventions.

Predictive value of PRECISE-DAPT score for long-term all-cause mortality in atrial fibrillation patients with non-ST-elevation myocardial infarction.

Introduction: Atrial fibrillation (AF) may co-exist in patients with non-ST-elevation myocardial infarction (NSTEMI). In patients with NSTEMI, AF should therefore be regarded as an important risk factor irrespective of its presentation. To predict outcomes in AF patients presenting with NSTEMI, early risk stratification can help to identify the patients with a possible poor long-term prognosis. The development of the PRECISE-DAPT score aimed to predict the risk of bleeding in patients who underwent stent implantation and received dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI), providing a valuable tool for assessing bleeding risk in this specific patient population. Aim: To assess the performance of the PRECISE-DAPT score in predicting long-term prognosis in AF patients with NSTEMI. Material and methods: Five hundred and twenty-six consecutive AF patients presenting with NSTEMI were included in the present study. The PRECISE-DAPT score was calculated in each case and evaluated for the association of increased mortality in the study population, who survived in-hospital but died in the long term. Results: All-cause mortality deaths occurred in 278 (52.6%) patients. Higher PRECISE-DAPT score, shorter duration of P2Y12 inhibitor therapy, decreased left ventricular ejection fraction (LVEF), and a history of diabetes mellitus (DM) were all associated with an increased risk of all-cause mortality in the multivariable logistic regression model. Conclusions: High PRECISE-DAPT score was associated with higher long-term all-cause mortality in AF patients presenting with NSTEMI.

The relation of polymer structure of stent used in patients with acute coronary syndrome revascularized by stent implantation with long-term cardiovascular events.

INTRODUCTION: Drug-eluting stents (DES) have revolutionized percutaneous coronary intervention (PCI) by improving event-free survival compared to older stent designs. However, early-generation DES with polymer matrixes have raised concerns regarding late stent thrombosis due to delayed vascular healing. To address these issues, biologically bioabsorbable polymer drug-eluting stents (BP-DES) and polymer-free drug-eluting stents (PF-DES) have been developed. AIM: The aim of the present study is to evaluate and compare the long-term effects of different stent platforms in patients with acute coronary syndrome (ACS) undergoing PCI. MATERIAL AND METHODS: We conducted a retrospective, observational study involving 1192 ACS patients who underwent urgent PCI. Patients were treated with thin- strut DP-DES, ultra-thin strut BP-DES, or thin-strut PF-DES. The primary endpoint was a composite of cardiac death, target vessel myocardial infarction (TVMI), and clinically driven target lesion revascularization (CITLR) at 12 months and 4 years. RESULTS: The baseline demographics and clinical characteristics of patients in the three stent subgroups were similar. No significant differences were observed in target lesion failure (TLF), cardiac mortality, TVMI, and stent thrombosis (ST) rates among the three subgroups at both 12 months and 4 years. However, beyond the first year, the rate of CITLR was significantly lower in the ultra-thin strut BP-DES subgroup compared to thin-strut DP-DES, suggesting potential long-term advantages of ultra-thin strut BP-DES. Additionally, both ultra-thin strut BP-DES and thin-strut PF-DES demonstrated lower ST rates after the first year compared to thin-strut DP-DES. CONCLUSION: Our study highlights the potential advantages of ultra-thin strut BP-DES in reducing CITLR rates in the long term, and both ultra-thin strut BP-DES and thin-strut PF-DES demonstrate lower rates of ST beyond the first year compared to thin-strut DP-DES. However, no significant differences were observed in overall TLF, cardiac mortality and TVMI rates among the three stent subgroups at both 12 months and 4 years.

The effect of urgent blood pressure reduction on left atrial strain in patients with hypertensive attack : Blood pressure lowering affects LA strain.

BACKGROUND: Left atrial (LA) strain is a robust measure of LA function and is a useful parameter to assess left ventricular filling pressure. While initially considered as a "load-independent" parameter of LA function, later studies have found that acute changes in LA preload may affect LA reservoir and contractile strains. Acute alterations in blood pressure (BP) induces a change in left ventricular (LV) filling pressure without imposing a volume load, thus providing an opportunity to assess the effects of the change in LA afterload on LA mechanics. This study aims to understand the effect of acute BP changes on LA strain. METHODS: A total of 40 patients admitted to the emergency department with hypertensive urgency were included. All patients underwent a comprehensive echocardiographic examination including measurement of LA reservoir, conduit and contractile strains. A repeat set of measurements were obtained after BP lowering. RESULTS: Average drop in mean BP following intervention was 18.1 ± 5.4%. LV end-systolic and end-diastolic volumes, as well as maximum and minimum LA volumes were decreased significantly after BP reduction. The absolute increases in reservoir and contractile strains were 2.3 ± 4.7% (7.9% ± 13.8% relative to baseline) and 2.5 ± 3.3% (13.5 ± 19.0% relative to baseline), respectively, with both changes being statistically significant (p = 0.003 for reservoir and p < 0.001 for contractile strains). There were no significant changes in conduit strain after BP intervention (p = 0.79). The change in both LA reservoir and contractile strains were more evident in those with a previous diagnosis of hypertension and those with a smaller degree of change in mean BP after intervention. CONCLUSION: In patients with an acute hypertension, lowering BP leads to an acute improvement in LA reservoir and contractile strains. Thus, acute changes in systemic BP should be considered when LA mechanics are evaluated.

Assessment of Right Ventricular Systolic Function with 3-Dimensional Speckle Tracking Echocardiography in Isolated Mild Mitral Stenosis.

BACKGROUND: In rheumatic severe mitral stenosis, right ventricular mechanics deteriorate with the increasing severity of mitral stenosis. Therefore, we aimed to investigate right ventricular mechanics in patients with mild mitral stenosis using 3-dimensional speckle tracking echocardiography. METHODS: In total, 40 patients with mild mitral stenosis and 36 age- and gender-matched healthy controls were included. Conventional echocardiographic examination was performed and 3-dimensional data sets were acquired for strain analysis. Besides conventional echocardiographic parameters, right ventricular volume and function and 3-dimensional speckle tracking echocardiography-derived right ventricular free wall longitudinal strain were compared between patients with mild mitral stenosis and healthy controls. RESULTS: Although 3-dimensional right ventricular volumes and ejection fraction were similar between the groups, 3-dimensional speckle tracking echocardiography-derived right ventricular free wall longitudinal strain was significantly lower in patients with mild mitral stenosis than in controls (25.57 ± 4.39% vs. 27.90 ± 4.71%, P =.028). Significant correlations were observed between right ventricular free wall longitudinal strain and mitral valve area and estimated systolic pulmonary artery pressure (r = 0.597, P <.001; r = -0.508, P =.003, respectively). Another significant positive correlation was observed between planimetric mitral valve area and 3-dimensional speckle tracking echocardiography-derived right ventricular free wall longitudinal strain (r = 0.597, P <.001). CONCLUSION: The degree of severity of mild mitral stenosis in terms of mitral valve area can help in the early detection of subclinical right ventricular systolic function impairment which can be easily detected by 3-dimensional speckle tracking echocardiography. Right ventricular contractile performance could decrease even in mild mitral stenosis.

Successful treatment of patent ductus arteriosus accompanying right-sided aortic arch and aberrant left subclavian artery: a case report.

Background: The coexistence of a right-sided aortic arch (RAA), an aberrant left subclavian artery (ALSA), and a patent ductus arteriosus (PDA) is a rarely seen vascular ring anomaly. There is currently no general guideline consensus on the management and follow-up of this congenital defect, posing a challenge to the clinicians. At this point, the heart team plays a critical role in the management of the disease. Case summary: In the present case, a 25-year-old male patient was presented to the outpatient clinic with dyspnoea and fatigue. A transthoracic echocardiography revealed PDA with a left-to-right shunt. To evaluate the anatomy thoroughly, a thoracic computed tomographic angiography was performed and showed PDA accompanying ALSA and RAA. The patient was evaluated by the Heart Team, and a percutaneous closure of PDA was recommended due to signs of left ventricular volume overload. The closure was successfully performed with Amplatzer vascular plug II. At follow-up, the patient was free of symptoms. Discussion: Clinicians should be aware of the potential concomitant lesions during the diagnostic work-up. In selected patients, percutaneous closure of PDA may be the first-line therapy in experienced centres.

Predictive value of the age, creatinine and ejection fraction score in patients undergoing primary percutaneous coronary intervention with bail-out tirofiban therapy.

INTRODUCTION: In patients who have undergone interventional cardiac procedures, the risk of bleeding is higher than in patients who received conservative treatment due to multiple medications and comorbidities. AIM: This study aimed to evaluate the usefulness of the age, creatinine and ejection fraction (ACEF) score for predicting bleeding events and to compare short- and long-term clinical outcomes according to the ACEF score in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) with bail-out tirofiban therapy (BOTT). MATERIAL AND METHODS: A total of 2,543 patients were included and divided into three groups according to the following ACEF score tertiles: T1 (ACEFlow ≤ 1.033), T2 (1.033 < ACEFmid ≤ 1.371), and T3 (ACEFhigh > 1.371). The main outcomes measured were the incidence rates of relevant bleeding events and mortality within 30 days and 3 years after the procedure. RESULTS: A total of 73 (2.9%) patients had Bleeding Academic Research Consortium bleeding events of grades 3, 4 or 5 and 104 (4%) patients died in a 30-day period. The ACEF score was effective at predicting 30-day bleeding (area under the receiver operating characteristic curve (AUC): 0.658, 95% confidence interval (CI): 0.579-0.737; p < 0.001), 30-day mortality (AUC = 0.701, 95% CI: 0.649-0.753; p < 0.001) and 3-year mortality (AUC = 0.778, 95% CI: 0.748-0.807; p < 0.001) events. Considering the ACEF score tertiles, T3 patients presented greater 30-day bleeding (1.6%, 2.8% and 4.1%; odds ratio (OR) = 2.56, 95% CI: 1.37-4.80), 30-day mortality (1.7%, 3.5% and 7.1%; OR = 4.53, 95% CI: 2.51-8.18) and 3-year mortality (6.4%, 11% and 19.8%; hazard ratio = 3.56, 95% CI: 2.58-4.91) risks. CONCLUSIONS: The ACEF score is a user-friendly tool with excellent predictive value for bleeding events and mortality in patients undergoing pPCI with BOTT.

Differences in clinical and echocardiographic variables and mortality predictors among older patients with pulmonary embolism.

BACKGROUND: An increase in short-term mortality can be found among older patients with hemodynamically stable acute pulmonary embolism (APE) who have signs of right ventricular (RV) dysfunction. AIMS: This study was designed to assess whether any difference exists among clinical, laboratory, electrocardiography and echocardiography parameters between older and younger patients diagnosed with APE. METHODS: The study sample included a total of 635 patients with confirmed APE who were divided into two groups of older (65 years and older) and younger (younger than 65 years) individuals. Comparisons were performed between these groups in terms of clinical, predisposing factors and laboratory, electrocardiographic and echocardiographic parameters. RESULTS: Analyses of 295 (46.4%) older and 340 (53.6%) younger patients diagnosed with APE were performed. Female sex, Pulmonary Embolism Severity Index score and baseline creatinine levels were higher in the older group. Also, the frequency of atrial fibrillation, RV outflow tract parasternal long-axis proximal diameter, RV end-diastolic diameter (RV-EDD) basal (apical four-chamber) and RV systolic pressure were significantly greater in older patients with APE. A total of 30 (4.7%) deaths were observed during the in-hospital period [21 (7.1%) older vs 9 (2.6%) younger patients; p < 0.01]. In the multivariate logistic regression analysis, age, white blood cell count (WBC), left ventricular ejection fraction (LVEF), RV-EDD basal and tricuspid annular plane systolic excursion (TAPSE) of less than 16 mm were found to be independently associated with in-hospital mortality. CONCLUSION: Older patients might experience greater rates of RV dilatation, RV dysfunction and atrial fibrillation during APE. In addition to age; elevated WBC, low LVEF, increased RV-EDD basal and TAPSE of less than 16 mm were independent predictors of mortality among study population.

Mean platelet volume/platelet count ratio as a predictor of stent thrombosis in patients with ST-segment-elevation myocardial infarction.

BACKGROUND: Despite the important role of some haematological parameters in tendency to thrombosis is known, their relationship with long-term stent thrombosis (ST) remains unclear. AIMS: This study aimed to investigate the association between the mean platelet volume (MPV) to platelet count (PC) ratio and long-term ST and mortality in patients with ST-segment-elevation myocardial infarction (STEMI) treated successfully by primary percutaneous coronary intervention (pPCI). METHODS: In a retrospective cohort study, according to their baseline MPV/PC ratios, 3667 consecutive STEMI patients undergoing pPCI were divided into three groups: tertile 1 (T1) (n = 1222, 0.357 ≥ MPV/PC ≥ 0.043), tertile 2 (T2) (n = 1222, 0.033 < MPV/PC < 0.043) and tertile 3 (T3) (n = 1223, 0.009 ≤ MPV/PC ≤ 0.032). Patients were followed up with for 5 years, focusing on ST and all-cause mortality outcomes. RESULTS: Patients with T1 displayed a greater 5-year ST rate, including a 2.76-fold greater (95% confidence interval 1.68-10.33) rate than that of patients with T3, who had the lowest rates and were used as the reference group. Meanwhile, the 5-year mortality rate was similarly higher among patients with T1 by 1.72 times (95% confidence interval 1.33-2.22) relative to that among patients with T3. These significant relationships persisted even after adjustment for all confounders. CONCLUSION: We found that higher MPV/PC ratios were associated with long-term ST and mortality. The MPV/PC ratio may constitute both a rapid and an easily obtainable parameter for identifying reliably high-risk patients who have undergone pPCI.

Speckle tracking echocardiography in severe patient-prosthesis mismatch.

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65 cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (n = 27) and those with normofunctional aortic prosthesis valve as a control group (n = 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6 ± 2.9 vs. 21.4 ± 2.1; p < 0.01) and GCS (17.2 ± 3.6 vs. 21.7 ± 2.1; p < 0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

The importance of mass diameter in decision-making for preoperative coronary angiography in myxoma patients.

OBJECTIVES: Although coronary angiography (CAG) is generally performed to rule out coexisting coronary artery disease in patients with cardiac myxoma, its necessity to evaluate vascular supply of the myxoma is debatable. The aim of this article is to evaluate clinical experience and CAG findings in our patient group. METHODS: This retrospective analysis was performed in 46 patients (17 men, mean age 57.7 ± 8.6 years), who underwent surgery with an indication for cardiac myxoma between 2004 and 2016 with a CAG performed preoperatively. All CAGs were evaluated in a blinded manner by a cardiac surgeon and a cardiologist separately. Correlations between the presence and pattern of feeding vessels, presence of an arteriocavity fistula (ACF), coronary arterial dominance, size of mass and clinical presentations were analysed. RESULTS: Coronary artery disease defined as >50% obstructive lesions was detected in 10 patients (21.7%). The tumour diameter was found to be significantly higher in patients who had an ACF and a dual-feeding artery (P = 0.049 and P = 0.0001, respectively). Additionally, there was a significant relationship between the presence of dual-feeding vessels and ACF (P = 0.014). ROC analysis revealed a cut-off point of 27 mm in diameter based on the presence of an ACF and a dual-feeding artery. In cases with a diameter of 27 mm or above, the risk of existence of an ACF was 4.68-fold greater, with a confidence interval of 95%, and a dual-feeding pattern was seen in all of them. CONCLUSIONS: This study suggests that preoperative CAG can be considered to detect feeding vessels that may lead to a steal phenomenon, which may alter the management in patients with myxoma greater than 27 mm in diameter.

Clinical usefulness of epicardial adipose tissue in patients with high-intermediate pre-test probability for coronary artery disease.

BACKGROUND: Epicardial adipose tissue (EAT) is thought to be associated with the extension and severity of coronary artery disease (CAD), and echocardiographic measurement of EAT thickness is considered to be a possible cardiovascular risk indica-tor. The European Society of Cardiology Task Force recommends further non-invasive testing in patients with an intermediate pre-test probability (PTP) for the diagnosis of CAD. AIM: We sought to evaluate the clinical usefulness of performing EAT measurements in patients with a high-intermediate PTP. METHODS: Patients referred to an outpatient clinic with stable chest pain symptoms, with PTP for CAD between 66% and 85%, were included in the study. Echocardiographic measurement of the EAT was identified as the echo-free space between the outer wall of the myocardium and the visceral layer of the pericardium. Single-photon emission computed tomography (SPECT) was performed in all patients. The diagnosis of CAD was based on the presence of reversible perfusion defects on SPECT. RESULTS: A total of 126 patients (76 men, 60.3%) with a mean age of 65.3 ± 9.1 years were recruited. The EAT thickness was 7.3 ± 0.7 mm in patients with positive SPECT and 6.2 ± 0.6 mm in patients with negative SPECT (p < 0.001). Multivariable analysis revealed higher rates of positive SPECT in patients with higher EAT (odds ratio [OR] 9.80; 95% confidence interval [CI] 3.72-25.79; p < 0.001), and receiver operating characteristic curve analysis showed that the greatest specificity was obtained when the cut-off value of EAT thickness was 6.75 mm (sensitivity 76%; specificity 74%). CONCLUSIONS: In patients with high-intermediate PTP, EAT is a useful measurement that may assist in risk stratification.

Value of the neutrophil-to-lymphocyte ratio in predicting left ventricular recovery in patients with peripartum cardiomyopathy.

OBJECTIVE: The aim of this study was to assess the value of the neutrophil-to-lymphocyte ratio (NLR) in predicting left ventricular (LV) recovery in patients with peripartum cardiomyopathy (PPCM). METHODS: Patients with PPCM (n = 40), who were admitted to our tertiary reference hospital between 2007 and 2015 were retrospectively analyzed. All patients were followed-up for at least 12 months after the diagnosis. All patients had standard echocardiographic examination at baseline and the last follow-up visit. Recovery of LV function was defined as the presence of LV ejection fraction (EF) >45%. Data on blood parameters were also collected at baseline. Univariate and multivariate analysis were used to assess the significant predictive variables for persistent LV systolic dysfunction. RESULTS: Of the patients 21 (52.5%) did not recover LV function at the last follow-up visit (nonrecovery group), while 19 of the patients (47.5%) exhibited LV recovery (recovery group). The LV EF and fractional shortening (FS) were significantly lower in the nonrecovery group. The baseline LV end-diastolic diameter, LV end-systolic diameter (LVESD) and systolic pulmonary arterial pressure were significantly increased in the nonrecovery group. The NLR, C­reactive protein and troponin levels were significantly higher in the nonrecovery group. In multivariate logistic regression analysis only NLR and LVESD were identified as independent predictors of persistent LV systolic dysfunction in patients with PPCM (p = 0.020 and p = 0.009 respectively). CONCLUSION: Elevated NLR and increased LVESD were independent prognostic factors in predicting persistent LV dysfunction in patients with PPCM. The NLR might assist in identifying high risk patients with PPCM.

Left ventricular mechanics in isolated mild mitral stenosis: a three dimensional speckle tracking study.

In a fraction of patients with mild mitral stenosis, left ventricular systolic function deteriorates despite the lack of hemodynamic load imposed by the dysfunctioning valve. Neither the predisposing factors nor the earlier changes in left ventricular contractility were understood adequately. In the present study we aimed to evaluate left ventricular mechanics using three-dimensional (3D) speckle tracking echocardiography. A total of 31 patients with mild rheumatic mitral stenosis and 27 healthy controls were enrolled to the study. All subjects included to the study underwent echocardiographic examination to collect data for two- and three-dimensional speckle-tracking based stain, twist angle and torsion measurements. Data was analyzed offline with a echocardiographic data analysis software. Patients with rheumatic mild MS had lower global longitudinal (p < 0.001) circumferential (p = 0.02) and radial (p < 0.01) strain compared to controls, despite ejection fraction was similar for both groups [(p = 0.45) for three dimensional and (p = 0.37) for two dimensional measurement]. While the twist angle was not significantly different between groups (p = 0.11), left ventricular torsion was significantly higher in mitral stenosis group (p = 0.03). All strain values had a weak but significant positive correlation with mitral valve area measured with planimetry. Subclinical left ventricular systolic dysfunction develops at an early stage in rheumatic mitral stenosis. Further work is needed to elucidate patients at risk for developing overt systolic dysfunction.

An unexpected complication of acute pancreatitis: Intra-cardiac thrombus.

Left atrial thrombus after acute pancreatitis (AP) is a rare clinical statement. Because of induction of systemic prothrombotic process by AP; some patients with underlying risk factors may develop an intra-cardiac thrombus. We present a 53years-old-woman with moderate mitral stenosis and atrial fibrillation. However the patient was under warfarin treatment, she developed a big left atrial big thrombus which was originated from left atrial appendage after she was suffered from AP.

The effects of weight loss after sleeve gastrectomy on left ventricular systolic function in men versus women.

PURPOSE: To evaluate and compare the effects of weight lost after sleeve gastrectomy on left ventricular (LV) systolic function using both two-dimensional speckle tracking (2D-STE) and three-dimensional echocardiography (3DE) in men versus women. METHODS: In 53 obese patients referred for sleeve gastrectomy, 2D-STE and 3DE were performed prior to and 6 months after surgery. RESULTS: The study included 53 obese patients (62.3% female; mean age 36.8 ± 10.7 years). Six months after surgery, all patients demonstrated a significant decrease in body mass index, body weight, blood pressure, heart rate, LV end-diastolic dimension, myocardial wall thickness, LV mass, LV mass index, LV mass/height(2.7) , LV end-diastolic volume, LV end-systolic volume, and stroke volume as well as an increase in SV index and ejection fraction. There was no significant difference in measured variables between men and women at baseline or postsurgery, except for baseline LV end-diastolic dimension, and baseline and after surgery LV mass, LV mass index, and LV mass/height(2.7) , which were all significantly higher in men. CONCLUSIONS: Sleeve gastrectomy improves LV systolic function and contributes to reverse LV remodeling in both genders. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:492-499, 2016.

The advantages of live/real time three-dimensional transesophageal echocardiography during assessments of pulmonary stenosis.

This report sought to compare live/real-time three-dimensional transesophageal echocardiography (3D-TEE) with two-dimensional transesophageal echocardiography (2D-TEE) and to determine whether there are advantages to using 3D-TEE on patients with pulmonary stenosis (PS). Sixteen consecutive adult patients (50 % male and 50 % female; mean age 33 ± 13.4 years) with PS and indications of TEE were prospectively enrolled in this study. Following this, initial 2D-TEE and 3D-TEE examinations were performed, and 3D-TEE images were analyzed using an off-line Q-lab software system. Finally, the 2D-TEE and 3D-TEE findings were compared. In the present study, 3D-TEE allowed us to obtain the en face views of pulmonary valves (PVs) in all but one patient. While this patient was without a PV due to a previous tetralogy of Fallot operation, we could detect the type of PV in the other 15 (93.7 %) patients by using 3D-TEE. Due to poor image quality, the most stenotic area was not measurable in only one (6.2 %) of the patients. In eight (50 %) of the patients, severity and localization of stenosis were more precisely determined with 3DTEE than with 2D-TEE. The PVs' maximal annulus dimensions were found to be significantly larger when they were measured using 3D modalities. This study provides evidence of the incremental value of using 3D-TEE rather than 2D-TEE during assessments of PS, specifically in cases where special conditions (pregnancy, pulmonary regurgitation, and concomitant atrial septal defects) cause recordings of the transvalvular peak gradient to be inaccurate. Therefore, 3D-TEE should be used as a complementary imaging tool to 2D-TEE during routine echocardiographic examinations.
