RESUMEN

OBJECTIVE: Access site-related vascular complications are common complications of trans- catheter aortic valve replacement. In this study, we aimed to investigate the efficacy and safety of prophylactic cannulation of the ipsilateral distal femoral artery in the management of access site-related vascular complications. METHODS: One hundred sixty-four patients, who were evaluated by the Heart Team of our institution and found eligible for transcatheter aortic valve replacement procedure between January 2016 and August 2019, were included in this retrospective study. Patients were divided into two groups according to the management of peripheral complications. The antegrade crossover was used as bailout treatment in the first 70 patients. Prophylactic cannulation of the ipsilateral distal femoral artery was performed in the last 94 patients. These 2 groups were compared. RESULTS: Peripheral complications developed in 15 of the first 70 patients included in the study. The percutaneous intervention was unsuccessful in 4 of the patients who underwent bailout antegrade crossover. Peripheral complications developed in 14 of the last 94 patients in whom prophylactic cannulation of the ipsilateral distal femoral artery was performed, and all these patients were managed successfully with percutaneous intervention. CONCLUSION: Prophylactic cannulation of the ipsilateral distal femoral artery is a simple, effec- tive, and safe method in the management of access site-related vascular complications.

RESUMEN

Studies reported conflicting results on the effect of renin-angiotensin-aldosterone system (RAAS) blocker use on acute kidney injury (AKI) in patients undergoing elective coronary angiography but association in elderly patients with ST-elevation myocardial infarction (STEMI) is not known. Also, there are limited data on the effect of inflammatory markers on AKI. We aimed to investigate the effects of RAAS blocker pretreatment and inflammatory markers on AKI in this population. A total of 471 patients were compared according to presence of RAAS blocker pretreatment at admission. Conventional and inverse probability weighed conditional logistic regression were used to determine independent predictors of AKI. Mean age of the study group was 75.4 ± 7.1 years and 29.1% of the patients were female. AKI was observed in 17.2% of the study population. Weighted conditional multivariable logistic regression analysis revealed that AKI was associated with baseline creatinine levels and C-reactive protein/albumin ratio (CAR) (OR 2.08, 95% CI = 1.13-3.82, p = .02 and OR 1.19, 95% CI = 1.01-1.41, p = .04, respectively). No significant association was found between RAAS blocker pretreatment and AKI. CAR and elevated baseline creatinine levels were independent predictors of AKI in this patient group.

RESUMEN

OBJECTIVE: Percutaneous closure of atrial septal defects is challenging in cases where the device is perpendicular to the septum during the procedure. Hence, different techniques, maneuvers, and auxiliary equipment may be required. We aimed to demonstrate the effectiveness of the FlexCath steerable catheter application in percutaneous closure of atrial septal defect cases in which the device was perpendicular to the septum. METHODS: Patients with atrial septal defect who presented to our clinic between January 2017 and December 2020 and were deemed eligible for percutaneous closure were included in the study. RESULTS: Atrial septal defects of 101 patients out of 110 patients were successfully closed using standard methods. Nine patients in whom it was seen if the device was perpendicular to the interatrial septum were successfully closed with FlexCath steerable catheter support. There was no statistically significant difference between patients in terms of age, gender, floopy rim, and multiple defects. In the group that was treated with FlexCath steerable catheter support, the aortic rim was smaller, and the defect diameter and the size of the atrial septal defects device were larger. The success of the procedure was 100% while using the flexcath steerable catheter in patients with the device perpendicular to the interatrial septum. There were no complica tions during the procedure. CONCLUSION: Percutaneous closure with FlexCath steerable catheter support in difficult cases with atrial septal defects was effective in those with the atrial septal closure device being per pendicular to the interatrial septum and was performed easily without any safety issues.

RESUMEN

PURPOSE: The aim of this study was to assess long-term left ventricular (LV) systolic function using 3D speckle tracking echocardiography in patients with complete LV recovery following peripartum cardiomyopathy (PPCM). METHODS: A total of 20 PPCM patients who exhibited LV recovery (ejection fraction ≥50%) in the follow-up period and 20 age-matched, healthy women were included in the study. Standard 2D echocardiographic examinations were performed. Global longitudinal strain and global circumferential strain were analyzed. RESULTS: Age, weight, body surface area, smoking, heart rate, and systolic and diastolic blood pressure were similar in both groups. Echocardiographic examination showed no significant difference between both groups. Only the global longitudinal strain (18.1 ± 2.7 vs 20.16 ± 1.7, p = 0.02) and global circumferential strain (22.1 ± 2.9 vs 24.4 ± 1.19, p = 0.01) were significantly lower in PPCM patients. The lowest values for longitudinal strain belonged to the basal and mid regions of anterior, anteroseptal and lateral walls in the PPCM patients. CONCLUSION: Subclinical myocardial damage may persist in PPCM patients with full LV systolic recovery. 3D Speckle Tracking strain analysis is a useful method for detecting subtle myocardial dysfunction.

RESUMEN

BACKGROUND: Ectatic infarct-related artery (IRA) has been shown to be associated with higher thrombus burden, no-reflow, stent thrombosis (ST) and major adverse cardiovascular events in patients with ST-elevation myocardial infarction (STEMI). The effect of ectatic non-IRA on ST without ectatic IRA is not known. We aimed to assess the effect of ectatic non-IRA presence on ST within 1 month after primary percutaneous intervention (pPCI) in patients with STEMI. METHODS: A total of 1541 patients with a diagnosis of STEMI and underwent pPCI between 2015 and 2020 were retrospectively included in the study. Patients with and without 1 month ST were compared. Penalised logistic regression method was used to assess the association between ST and candidate predictors due to the risk of overfitting. RESULTS: Median age of the study group was 56.5 (48.7 to 67.2) years. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score, ectatic non-IRA presence and use of tirofiban were significantly higher in the ST group (18.2±9.9 vs 15.1±9.9, p=0.03; 25% vs 7.2%, p<0.001; 54.2% vs 30.5%, p<0.001; respectively). Significantly higher thrombus aspiration (14.3% vs 6.7%, p=0.03) and lower stent implantation (67.7% vs 84%, p<0.001) rates were observed in ectatic IRA group compared with ectatic non-IRA group. In multivariable analysis, ectatic non-IRA presence was independently associated with 1-month ST (OR 4.01, 95% CI 1.86 to 8.63, p=0.01). CONCLUSION: Ectatic non-IRA presence without ectatic IRA in patients with STEMI increases the risk of ST within the first month of pPCI.

RESUMEN

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.

RESUMEN

BACKGROUND: An increased risk of ischemic stroke has been reported in patients with Parkinson's disease (PD). Atrial fibrillation (AF) is strongly associated with ischemic stroke. Prolonged atrial electromechanical delay (EMD) is an independent predictor for the development of AF. AIMS: The aim of the present study was to evaluate the atrial conduction parameters in patients with PD and to assess their relation with the severity of PD. STUDY DESIGN: We prospectively enrolled 51 consecutive patients with newly diagnosed PD and 31 age- and sex-matched non-PD subjects. METHODS: To assess atrial electromechanical coupling (PA), the time intervals from the onset of p wave on ECG to the late diastolic wave at the septal (PAs) and lateral (PAl) mitral annulus and lateral tricuspid annulus (PAt) were measured on Tissue Doppler Echocardiography (TDE). The difference between PAs-PAl, PAs-PAt, and PAl-PAt were defined as left intra-atrial, right intra-atrial, and interatrial EMD, respectively. P-wave dispersion (PWD) was calculated from the 12-lead ECG. RESULTS: PWD, PAs, PAl, and PAt durations were significantly prolonged in the PD group (all p < 0.001). Interatrial, right, and left intra-atrial EMD were also significantly longer in PD patients (p < 0.001, p < 0.001 and p=0.002, resp.). There were significant positive correlations between disease severity (UPDRS score) and PWD (r=0.34, p=0.041), left intra-atrial (r=0.39, p=0.005), and interatrial EMD (r=0.35, p=0.012). By multivariate analysis, PWD (OR: 1.13, 95% CI: 1.02-1.25; p=0.017), LA volume index (OR: 1.19, 95% CI: 1.02-1.37; p=0.021), left intra-atrial (OR: 1.12, 95% CI: 1.01-1.24; p=0.041), and interatrial EMD (OR: 1.08, 95% CI: 1.01-1.16; p=0.026) were found as independent predictors of PD. CONCLUSION: Atrial conduction times were longer and correlated with the severity of disease in PD patients. Prolonged inter- and intra-atrial-EMD intervals were also found as independent correlates of PD. These findings may suggest an increased predisposition to atrial fibrillation in PD.

RESUMEN

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.

RESUMEN

OBJECTIVE: In this study, we aimed to investigate the left atrial (LA) electrical and mechanical functions in patients with metabolic syndrome (MetS). SUBJECTS AND METHODS: The study population consisted of 87 patients with MetS and 67 controls. Intra-atrial and interatrial electromechanical delays (EDs) were measured with tissue Doppler imaging. P-wave dispersion (Pd) was calculated from the 12-lead electrocardiograms. LA volumes were measured echocardiographically by the biplane area-length method. RESULTS: Intra-atrial and interatrial EDs and Pd were significantly higher in patients with MetS (10.3 ± 6.3, 21.0 ± 11.5 and 41.7 ± 10.8) than in controls (7.4 ± 5.5, 12.3 ± 10.4 and 29.2 ± 7.4; p = 0.003, p < 0.001 and p < 0.001, respectively). The LA preatrial contraction volume and active emptying volumes were higher in this population, but the LA passive emptying fraction was lower. In the multivariate linear regression analysis, the presence of MetS, LA active emptying volume and left ventricular early diastolic (E) wave velocity/late diastolic (A) wave velocity (E/A) ratios were independent correlates of interatrial ED (p = 0.002, p = 0.001 and p = 0.025, respectively). CONCLUSIONS: This study showed that intra-atrial and interatrial EDs and Pd were prolonged and LA mechanical functions were impaired in patients with MetS.

RESUMEN

Behçet's disease (BD) is a multisystem vasculitis that may involve vessels of all sizes. Acute coronary syndrome (ACS) due to secondary involvement of BD is rare and its management less clear. In this case, a 29-year-old man admitted to the emergency room with ongoing chest pain was interned to the coronary care unit with a diagnosis of ACS. The patient had been diagnosed 1 year before with BD and had been without regular follow-up, despite the suggested use of cholchium. An immediate coronary angiography revealed a fresh thrombus image in the proximal segment of the right coronary artery (RCA), an aneurysm of the left anterior descending artery (LAD) at proximal segment, and a hemodynamically significant lesion following the aneurysm. Intervention was ended because of normal flow (TIMI III) of distal RCA. An intravenous infusion of glycoprotein IIb/IIIa receptor inhibitor (tirofiban) was administered, and a control angiography showed dissolution of a thrombus in RCA, but enlarged aneurysm of LAD and a new aneurysm in RCA.

RESUMEN

The management of valvular heart diseases with mechanical valves has been performed for several years. Warfarin has been used in patients with mechanical heart valves to protect against thromboembolic complications; nevertheless, in these patients, thromboembolic event rates range from 0.5% to 1.7%. Acute occlusive embolism to the coronary arteries due to a mechanical valve is an uncommon occurrence. In this report, we present a case of a left coronary system occlusion due to thrombus embolization from a prosthetic aortic valve, which was successfully treated by thrombolytic therapy.

RESUMEN

The concept that coronary artery ectasia (CAE) is an inflammatory-related disease has been increasingly recognized. Periodontitis induced low-grade chronic systemic inflammation has been shown to be associated with cardiovascular diseases. The aim of the present study was to evaluate the association between periodontitis and CAE.Thirty-two patients with isolated CAE, and 28 age, sex and smoking status-matched subjects with normal coronary arteries (NCA) underwent full dental examinations. Periodontal disease was evaluated using the following clinical parameters; number of remaining teeth, plaque index (PI), gingival index (GI), bleeding on probing (BOP), and pocket depth (PD).Cases and controls did not differ according to their baseline characteristics and prevalence of traditional cardiovascular risk factors. Patients with isolated CAE had higher periodontal indices when compared to subjects with NCA (PD: 3.6 ± 1.26 mm versus 2.3 ± 0.79 mm; GI: 2.29 ± 0.86 versus 1.43 ± 1.19; BOP (%): 52.18 ± 20.1 versus 27.8 ± 10.9, P < 0.001, P < 0.05 and P < 0.05, respectively). Moreover, in multivariate analysis higher values for PD were found to be significant predictors for the likelihood of having coronary ectasia.The results of the present study demonstrate for the first time that there is an association between periodontitis and isolated CAE.

RESUMEN

BACKGROUND: It has been shown that left ventricular diastolic dysfunction (LVDD) develops in patients with metabolic syndrome (MetS). However, there is not sufficient evidence in the literature to determine whether this condition is due to increase in blood pressure, which is frequently encountered in MetS. The purpose of this study was to test the hypothesis whether LVDD in MetS is independent from the presence of hypertension. METHODS: A total of 60 patients diagnosed with MetS and 30 healthy people, who were age- and gender-matched with the patient group, were included in the study as the control group. In the study group, 30 of the patients were normotensive whereas the other 30 had hypertension. Conventional echocardiographic examinations and tissue Doppler imaging were performed besides measurements of demographic and biochemical parameters. RESULTS: In the hypertensive MetS group, early diastolic filling flow (E), early diastolic mitral annular velocity (E'), and E/A ratio were significantly lower compared to the control group. Late diastolic filling flow (A), deceleration time (DT), late diastolic mitral annular velocity (A'), and E/E' ratio were higher in the hypertensive MetS group than the control group. In the normotensive MetS group, E, E', and E/A ratio were also lower compared to the control group whereas DT, A', and E/E' ratio were higher. CONCLUSION: These findings support the idea that LVDD may develop in patients with MetS even in the absence of hypertension. In addition, co-existence of hypertension with MetS contributes to further worsening of diastolic functions.

RESUMEN

BACKGROUND: Coronary slow flow (CSF) is characterised by delayed opacification of coronary arteries in the absence of epicardial occlusive disease. It has been reported that CSF may cause angina, myocardial ischaemia, and infarction. Fragmentation of QRS complex (fQRS) is an easily evaluated non-invasive electrocardiographic parameter. It has been associated with alternation of myocardial activation due to myocardial scar and/or ischaemia. Whether CSF is associated with fQRS is unknown. The presence of fQRS on ECG may be an indicator of myocardial damage in patients with CSF. AIM: To investigate the presence of fQRS in patients with CSF. METHODS: Sixty patients (mean age 55.5 ± 10.5 years) with CSF and 44 patients with normal coronary arteries without associated CSF (mean age 53 ± 8.4 years) were included in this study. The fQRS was defined as the presence of an additional R wave or notching of R or S wave or the presence of fragmentation in two contiguous leads corresponding to a major coronary artery territory. RESULTS: The presence of fQRS was higher in the CSF group than in the controls (p = 0.005). Hypertension was significantly more common in the CSF group (p < 0.001). There was no significant association between the presence of fQRS and an increasing number of vessel involvements. Logistic regression analysis demonstrated that the presence of CSF was the independent determinant of fQRS (OR = 10.848; 95% CI 2.385-49.347; p = 0.002). CONCLUSIONS: Fragmented QRS, indicating increased risk for arrhythmias and cardiovascular mortality, was found to be significantly higher in patients with CSF. We have not found an association between the presence of fragmented QRS and the degree of CSF. Further prospective studies are needed to establish the significance as a possible new risk factor in patients with CSF.

RESUMEN

BACKGROUND: We aimed to evaluate the effect of surgical repair on right ventricular (RV) function in patients with pectus excavatum (PE) and RV compression by Doppler echocardiography. MATERIALS AND METHODS: Twenty-three patients who were admitted to our hospital for surgical correction of PE between 2009 and 2012 were included in the study. After transthoracic echocardiographic evaluation, 16 patients with RV compression were enrolled. All patients were males (100%) with a mean age of 20.5 ± 5.6 years. Transthoracic echocardiography was repeated 1 month after surgery. Echocardiographic evaluation included the assessment of RV diastolic diameter, tricuspid annular plane systolic excursion (TAPSE), pulsed tissue Doppler systolic velocity (S'), RV isovolumic acceleration (RV IVA), systolic pulmonary artery pressure, left ventricular (LV) ejection fraction, and myocardial performance indexes of both the right and the left ventricles (Tei index). RESULTS: Following the surgery, the RV end-diastolic diameter, TAPSE, S', and RV IVA were found to be significantly increased in patients with PE. In addition, RV and LV Tei index significantly improved after surgical correction. CONCLUSIONS: RV function significantly improved after corrective surgery. Quantitative echocardiographic examination provides accurate estimation when deciding for corrective surgery and also should be used in the assessment of postoperative improvement.

BACKGROUND: Our main purpose in this study is to compare atrial (inter-atrial, intra-left atrial, intra-right atrial) electromechanical delays of patients with lone atrial fibrillation (LAF) with healthy individuals and examine the relationship of annual LAF attack frequency. METHODS: 32 entirely healthy individuals and 32 patients who have presented with tachycardia and complying with LAF criteria have been included in the study. The time passing from the beginning of the P wave on electrocardiography to the A' wave on tissue Doppler trace was accepted as the atrial conduction time (PA'). The PA' time difference between the mitral annulus of left ventricle (ML) and the tricuspid annulus of right ventricle (TL) was defined as inter-atrial electromechanical delay (IA-EMD), the PA' time difference between the ML and septal mitral annulus (MS) as intra-left electromechanical delay (ILeft-EMD), the PA' time difference between MS and the TL as intra-right electromechanical delay (IRight-EMD). RESULTS: ILeft-EMD (21.8 ± 9.1 vs. 14.1 ± 4.9, p < 0.001), IRight-EMD (9.3 ± 6.8 vs. 5.9 ± 4.9, p = 0.03) and IA-EMD times (24.7 ± 11.2 vs. 11.9 ± 7.1, p < 0.001) were significantly longer in LAF patients. In multivariate regression analysis, using a model including age, gender and left atrium (LA) volumes, ILeft-EMD times (OR 1.14, 95% CI 1.03-1.27,p = 0.012), IA-EMD times (OR 1.12, 95% CI 1.03-1.23, p = 0.007) and LA volumes (OR 1.18, 95% CI 1.05-1.32, p = 0.005) were independent predictors of LAF. In LAF group, the frequency of AF episodes was significantly correlated with ILeft-EMD (r = 0.90, p < 0.001) and IA-EMD times (r = 0.36, p < 0.004), whereas, IRight-EMD times and LA volumes were not correlated with recurrence rates. CONCLUSIONS: ILeft-EMD and IA-EMD may increase in the early stages of atrial fibrillation even without the left atrial dilation and may be more valuable than left atrial area and volume in predicting atrial fibrillation.

RESUMEN

BACKGROUND: Atherosclerosis and arterial stiffening may coexist and the correlation of these parameters in patients with premature coronary artery disease (CAD) has not been well elucidated. Tissue Doppler imaging of the ascending aorta may be used in the assessment of elastic properties of the great arteries. OBJECTIVE: To investigate the correlation between aortic stiffness and premature CAD using parameters derived from two-dimensional and tissue Doppler imaging (TDI) echocardiography of the ascending aorta. METHODS: Fifty consecutive subjects younger than 40 years old who were hospitalized with diagnosis of acute coronary syndrome and had undergone coronary angiography were recruited. The control group included 70 age-sex matched individuals without a diagnosis of CAD. Aortic stiffness index (SI), aortic distensibility (D), and pressure-strain elastic modulus (Ep) were calculated from the aortic diameters measured by two-dimensional M-mode echocardiography and blood pressure obtained by sphygmomanometry. Aortic systolic velocity (SAo), and early (EAo) and late (AAo) diastolic velocities were determined by pulse-wave TDI from the anterior wall of ascending aorta 3cm above the aortic cusps in parasternal long-axis view. RESULTS: Stiffness index was higher [median 5.40, interquartile range (IQR) 5.98 vs. median 4.14 IQR 2.43; p=0.03] and distensibility was lower (median 2.86×10(-6)cm(2)/dyn, IQR 2.51×10(-6)cm(2)/dyn vs. median 3.46×10(-6)cm(2)/dyn, IQR 2.38×10(-6)cm(2)/dyn; p=0.04) in patients with CAD compared to the control group. EAo was significantly lower in the CAD group (7.2±1.8cm/s vs. 9.2±2.4cm/s, p<0.01). The difference in EAo remained significant when CAD patients with a left ventricular ejection fraction >55% was compared to the control group. SAo and AAo velocities of ascending aorta were similar in control and CAD groups. There was a significant correlation between EAo velocity and aortic stiffness index (r=-0.28, p=0.01), distensibility (r=0.19, p=0.04) and elastic modulus (r=-0.24, p=0.01). In multivariate regression analysis, decreased levels of high-density lipoprotein cholesterol [odds ratio (OR): 1.12 95% CI 1.06-1.19; p=0.01] and EAo (OR: 1.41 95% CI 1.12-1.79; p=0.01) measurements remained as the variables independently correlated with premature CAD in the study group. CONCLUSION: Arterial stiffness is increased in patients with premature CAD. EAo of the anterior wall of ascending aorta measured with pulse-wave TDI echocardiography is correlated with arterial stiffening and is decreased in patients with premature CAD.
