RESUMEN

PURPOSE: The use of ultrasound in peripheral blocks has now become the gold standard. Ultrasound is a method that is easy to apply and most importantly does not carry any risk, and its only disadvantage is based on the skill and knowledge of the practitioner. Injury to vascular structures, which is the most common occurrence in peripheral block applications, has been significantly reduced by the use of ultrasound. The aim of this study is to determine the location of nerve branches and to determine the most common anthropometric parameters in the axillary fossa. In this way, the common anatomy of the axillary BP will be determined and will guide the practitioners while performing the axillary plexus block. DESIGN: Observational Clinical Study. METHODS: The patients were positioned with forearm abducted 90 degrees and elbow flexed 90 degrees. A high-frequency linear ultrasound probe was placed on the lateral border of the pectoralis major muscle in the transverse plane. Pulsation of the axillary artery was visualized and shifted slowly to view the nerves around the artery. The axillary vein was also visualized to facilitate the movement of the transducer and to find the nerve localization more easily. The regions on the prepared wheel were marked. At the same time, demographic information such as gender, age, weight, and height of the patients were also recorded. FINDINGS: The sample was 248 patients, 61.3% female and 38.7% male. Our results showed that only 59% were compatible with the most common nerve locations in cadaveric dissections and the locations described in anatomy textbooks. CONCLUSIONS: Since there are many anatomical variations, validation of nerves with a nerve stimulator as well as simultaneous visual application under ultrasound guidance will increase the success chance of axillary brachial plexus block and protect it from unwanted complications.

RESUMEN

BACKGROUND: Effect of pulmonary hypertension (PH) on right ventricular (RV) geometry constitutes an ideal target to assess both pulmonary artery pressure (PAP) and its physiological importance. In this study, we evaluated the diagnostic power of the basal segment of septomarginal trabeculation (SMT) in predicting the PH and RV hypertrophy by cardiovascular magnetic resonance (CMR) in patients with idiopathic pulmonary arterial hypertension (IPAH) and Eisenmenger's syndrome (ES). METHODS: Eleven patients with IPAH, seven patients with ES, and 20 healthy controls were enrolled. CMR was used to measure the area and the thickness of the basal segment of SMT and right ventricular free wall (RVFW). Pulmonary artery systolic pressures (PASPs) were estimated by transthoracic echocardiography (TTE) with continuous-wave Doppler analysis measuring maximal tricuspid regurgitation (TR) velocity. Late gadolinium enhancement (LGE) findings of CMR and brain natriuretic peptide (BNP) levels were also obtained in all patients and control group. RESULTS: The area and the thickness of the basal segment of SMT were higher in patients with IPAH and ES than control group (P<.001). Pulmonary artery dimension, end-diastolic diameter of RV, RVFW thickness, and BNP levels were found to be significantly correlated with PAP (P<.001). LGE was present at the insertion point of RV only in patients group (P<.001). CONCLUSIONS: Increased area and thickness of the basal segment of SMT are easily measurable noninvasive markers of PH in patients with IPAH and ES.

RESUMEN

BACKGROUND: This study sought to compare various outcomes among a new specifically designed transcatheter paravalvular leak closure (TPVLC) device and the devices that are being utilized off-label. METHODS: Between April 2012 and January 2015, in a prospective two-center study, 52 patients who needed surgical reintervention due to a hemodynamically significant prosthetic paravalvular leak were studied. This study population was divided into two groups. Group I was composed of 32 patients who underwent paravalvular leak (PVL) closure with the currently available devices that are being utilized off-label, while group II consisted of 20 patients who were treated with the new specifically designed Occlutech PVL device. RESULTS: Demographic and clinical variables indicated a higher rate of atrial fibrillation (P = 0.027) and chronic obstructive airway disease (P = 0.009) in group II. The apical approach was the most commonly used intervention route used for group II (P = 0.019). The procedural success rate was 100% (29 of 29 leaks) in group II while the rate was 92% (39 of 42 leaks) in group I. However, more secondary events were observed in group I, but they did not reach statistical significance (8 vs. 1, P = 0.064). CONCLUSIONS: With its high procedural success rate and encouraging outcome results, the Occlutech device seems to satisfy the expectations of a specifically designed PVL closure device. © 2016 Wiley Periodicals, Inc.

RESUMEN

A 37 year-old female patient in whom the transthoracic echocardiography examination revealed dilatation of left heart chambers with left ventricular ejection fraction of 30% and moderate-to-severe mitral valve regurgitation was admitted to our hospital. On 2DTEE examination, mitral valve was normal; however, on 3D images, clefts of both anterior and posterior leaflets were revealed. Isolated cleft mitral valve without any other feature of atrioventricular septal defect is uncommon. 2D echocardiography has limited capability in defining the complex 3D anatomic characteristics of the cleft. 3DTEE allows to visualize the cleft position, morphology, and size, and it is important for surgical planning.

RESUMEN

PURPOSE: There are different clinical cardiac applications of dual source computed tomography (DSCT). Here, we aimed to compare the DSCT with the transthoracic echocardiography (TTE) for evaluating the Wilkins score and planimetric mitral valve area (MVA) of a rheumatic stenotic mitral valve. MATERIALS AND METHODS: We prospectively evaluated mitral valvular structure and function in 31 patients with known mitral stenosis undergoing electrocardiogram-gated, second-generation DSCT, in our heart center for different indications. Mitral valve was evaluated using Wilkins score, and also, the planimetric MVA was assessed. RESULTS: We found a significant difference between MVAs determined by DSCT (average 1.42 ± 0.44 cm2) and MVAs determined by TTE (average 1.35 ± 0.43 cm2 ; difference 0.07 ± 0.16 cm2; P = 0.018). Linear regression analysis revealed a good correlation between the two techniques (r = 0.934; P < 0.0001). The limits of agreement for DSCT and TTE in the Bland-Altman analysis were ±0.31 cm2 . DSCT using TTE as the reference enabled good discrimination between mild and moderate-to-severe stenosis and had an area under the ROC curve of 0.967 (CI 0.912-1.023; P < 0.0001). Wilkins scores obtained by DSCT (7.51 ± 1.17, range 5-10) and TTE (8.16 ± 1.27, range 6-10) had a moderate correlation (r = 0.686; P < 0.0001). CONCLUSION: We found that planimetric MVA measurements assessed by DSCT were closely correlated with MVA calculations by TTE. The moderate correlation was observed for the Wilkins score.

RESUMEN

BACKGROUND: Fragmented QRS (fQRS) arises from impaired ventricular depolarization due to heterogeneous electrical activation of ischemic and/or infarcted ventricular myocardium. The short- and long-term prognostic values of fQRS have been reported for myocardial infarction, heart failure, fatal cardiac arrhythmias, and sudden cardiac death. The aim of this study was to investigate the predictive value of admission fQRS complex for in-hospital cardiovascular mortality of patients with type 1 acute aortic dissection (AAD). METHODS: In this retrospective study, 203 consecutive patients with type 1 AAD who had been admitted to either of two large-volume tertiary hospitals between December 2008 and October 2013 were included. The patients were divided into two groups according to the presence or absence of the fQRS complex on admission. RESULTS: In-hospital cardiovascular mortality (P < 0.001), major adverse cardiovascular events (P < 0.001), acute renal failure (P = 0.022), multiorgan dysfunction (P < 0.001), and acute decompensated heart failure (P < 0.001) were observed to be significantly more frequent in the fQRS-positive group than in the fQRS-negative group. fQRS (odds ratio [95% confidence interval]: 4.184 [1.927-9.082], P < 0.001), operation duration (4.184 [1.927-9.082], P = 0.001), and Killip class IV (3.900 [1.699-8.955], P = 0.001) were found to be significant independent predictors of in-hospital cardiovascular mortality after adjustment of other risk factors in the multivariate analysis. CONCLUSIONS: fQRS is a simple, inexpensive, and readily available electrocardiographic entity that provides an additional risk stratification level beyond that provided by conventional risk parameters in predicting in-hospital cardiovascular mortality in type 1 AAD.

RESUMEN

OBJECTIVES: Fragmented QRS (fQRS) has been found to be associated with high mortality and arrhythmic events in acute coronary syndromes. Regional systolic function using wall motion score index (WMSI) is an alternative to left ventricular ejection fraction (LVEF) for the assessment of left ventricular systolic function. The aim of this study was to investigate the relation between the presence of fQRS on admission electrocardiogram (ECG) and WMSI in ST elevation myocardial infarction (STEMI) underwent primary coronary intervention (PCI). The in-hospital and long-term prognostic significance of persistent fQRS was also evaluated. METHODS: In this retrospective study, 542 patients with a diagnose of STEMI underwent primary PCI were included. Study patients were divided into two groups according to the presence (n = 153) or absence (n = 389) of a fQRS on admission ECG. RESULTS: WMSI was found to be significantly higher in fQRS(+) group compared to the fQRS(-) group (P < 0.001). In multivariete analysis, WMSI was found to be an independent predictor of fQRS, and fQRS was inversely associated with LVEF. The in-hospital reinfarction (P = 0.003), MACE (P = 0.024), intraaortic balloon pump use (P = 0.014), and advanced heart failure (P < 0.001) were found to be significantly more frequent in the fQRS(+) group. The presence of fQRS on admission was found to be associated with an increase in long-term cardiovascular mortality (P = 0.028), and long-term all-cause mortality (P = 0.022). CONCLUSION: WMSI was significantly related with the presence of the fQRS, which reflects the linking between impairment of regional left ventricular systolic function and the presence of severe myocardial injury in STEMI.

RESUMEN

UNLABELLED: Abstract Objectives: To evaluate subclinical left ventricular and right ventricular systolic impairment in dipper and non-dipper hypertensives by using isovolumic acceleration. METHODS: About 45 normotensive healthy volunteers (20 men, mean age 43 ± 9 years), 45 dipper (27 men, mean age 45 ± 9 years) and 45 non-dipper (25 men, 47 ± 7 years) hypertensives were enrolled. Isovolumic acceleration was measured by dividing the peak myocardial isovolumic contraction velocity by isovolumic acceleration time. RESULTS: Non-dippers indicated lower left ventricular (2.2 ± 0.4 m/s(2) versus 2.8 ± 1.0 m/s(2), p < 0.01) and right ventricular isovolumic acceleration values (2.8 ± 0.8 m/s(2) versus 3.5 ± 1.0 m/s(2), p = 0.012) compared with dippers. Left ventricular mass index (p = 0.001), interventricular septal thickness (p = 0.002) and myocardial performance index (p < 0.001) were negatively correlated with left ventricular isovolumic acceleration. Left ventricular septal thickness (p = 0.002), mass index (p = 0.001) and right ventricular myocardial performance index (p < 0.001) were negatively correlated with right ventricular isovolumic acceleration. CONCLUSION: The present study demonstrates that non-dipper hypertensives have increased left and right ventricular subclinical systolic dysfunction compared with dippers. Isovolumic acceleration is the only echocardiographic parameter in predicting this subtle impairment.

RESUMEN

Behçet's disease is a chronic multisystem inflammatory disorder. There are limited data about cardiac involvement, but it is seen rarely. Herein, we present a 33-year-old male patient with heart failure secondary to a right ventricular mass. It was first diagnosed as inflammatory myofibroblastic tumor (IMT) histopathologically. During the postoperative follow-up, a thrombus was detected at the interatrial septum, and the patient was reevaluated. The diagnosis was possible Behçet's disease, and the mass, previously reported as IMT, was determined to be an organizing thrombus with a mixture of granulation tissue and thrombotic material.

RESUMEN

In this study, we aimed to investigate the perioperative complications of the patients who underwent scoliosis surgery in our hospital and the factors that may affect the outcome. Between 2014 and 2018, scoliosis patients recorded data was examined retrospectively. Age, gender, height, body weight, comorbidity, Cobb index, scoliosis etiology, operation time, preoperative and postoperative hemoglobin, hematocrit, leukocyte, blood urea nitrogen, creatinine, coagulation value, operation time, level of instrumentation, intraoperative and postoperative blood loss, blood transfusion, intraoperative fluid administration, preoperative pulmonary function test values, blood gas values, urine outputs, hospital (LOS) and post anesthesia care unit stays, complications and mortality rates were examined. The files of 77 patients (48 female, 29 male) were retrospectively analyzed. The average age was 19.54 ±â€…16.32 years and 98.7% were elective surgery. The mean of LOS was 13.55 ±â€…9.13 days. As the preoperative hematocrit value decreases, LOS increases significantly. In patients with chronic obstructive pulmonary disease, smokers and high ASA scores, LOS is prolonged in patients with previous operations. As intraoperative colloid administration increased, crystalloid and blood products increased, it was also observed that the amount of crystalloid increased LOS. As the amount of intraoperative colloid or red blood cell administration increases, the duration of surgery and anesthesia increases, also increases the duration of post anesthesia care unit. Compared to patients with complications (n = 29) to the patients without complications (n = 47), it was found that they had longer anesthesia, and surgery times, also longer LOS times (P < .05). Our study showed that chronic obstructive pulmonary disease in the preoperative period, smoking, high ASA score, excessive use of colloid, prolonged duration of surgery and anesthesia, and long intubation durations increase the length of hospital stay. Preoperative comorbidity is directly related to postoperative complications and causes longer hospitalization after reconstructive scoliosis surgery.

RESUMEN

AIM: The aim of our study was to evaluate atrial electromechanical delay (AEMD) and left atrial mechanical functions (LAMF) in the patients with secundum-type atrial septal defect (ASD). METHOD: We included 72 patients with secundum type ASD in the study group and 35 gender and age-matched healthy volunteers for the control group. Maximal, minimal, and presystolic LA volumes were measured by modified Simpson method and indexed to the body surface area (BSA). Inter-AEMD, right and left intra-AEMD were measured from the lateral and septal mitral annulus and tricuspid annulus using tissue Doppler imaging (TDI). RESULTS: The age, gender, systolic and diastolic blood pressure, heart rate (HR), BSA, and body mass index (BMI) parameters were not significantly different between the groups. Left atrial active and total emptying fractions and conduit volumes were significantly lower in the patients with ASD compared with the control group (P = 0.006, P = 0.001, and P = 0.032, respectively). Total emptying volume was increased in patients with ASD (P = 0.021). Passive emptying volume and fraction and active emptying volumes were not different significantly between the groups (P > 0.05). The left intraatrial, right intraatrial, and inter-AEMDs were significantly longer in the ASD group (P = 0.032, P = 0.013, and P = 0.003, respectively). CONCLUSION: The left atrial reservoir and contractile pump functions are reduced; the left intraatrial, right intraatrial, and inter-AEMDs are increased in the patients with ASD.

RESUMEN

Axillary nerve blocks are commonly using for forearm and hand surgery. Especially for finger replacement it has been shown continuous plexus blockade improves microcirculation. Addition to that benefit continuous blockade provides adequate analgesia. In this study perfusion index (PI) and plethysmographic variability index (PVI) changes were used to evaluate in blocks success. The PVI and PI values were detected by a Radical-7TM finger pulse oximetry device (Massimo Corp, USA) in both fingers of 50 plastic surgery patients, who received an axillary brachial plexus catheter before surgery. Data recorded at baseline, during catheter replacement, after catheter replacement, and before surgery. All periods hemodynamic data, visual analog scala, Ramsey sedation score and patient satisfaction score were collected. In all 110 patients blocks were successfully applied, PI values in blocked arm increased after local analgesic application (during catheter replacement), (P < .05), PVI values were decreased in the same period but there were no statistical significance. The PI increases after peripheral plexus blockade and may be used as an indicator for successful block placement in awake patient. And also, it may be used as an indicator for catheter effectiveness after surgery. But PVI values cannot detect that kind of relation with nerve blockade.

RESUMEN

STUDY OBJECTIVE: To evaluate the quality of analgesia and the severity of side effects of intrathecal morphine administered for a dose range of 0.0 to 0.4 mg for postcesarean analgesia with low-dose bupivacaine. DESIGN: Double-blind, randomized study. SETTING: University hospital. PATIENTS: 100 ASA physical status I and II term parturients undergoing cesarean delivery with spinal anesthesia in the operating room. INTERVENTIONS: Patients were randomized to one of 5 groups to receive 0.0, 0.1, 0.2, 0.3, or 0.4 mg intrathecal morphine in addition to low-dose (7.5 mg) heavy bupivacaine. Each patient received intravenous (IV) patient-controlled analgesia (PCA) with morphine after the operation. MEASUREMENTS: 24-hour IV PCA morphine use and visual analog scores for pain were recorded. The severity score (4-point scale) of nausea, vomiting, and pruritus were assessed intraoperatively and at 4-hour intervals during the first 24 hours postoperatively. MAIN RESULTS: PCA morphine use was higher in the control group (0.0 mg) than in groups receiving 0.1, 0.2, 0.3, or 0.4 mg intrathecal morphine. There was no difference in IV PCA morphine use between the 0.1 and 0.4-mg groups, despite a 4-fold increase in intrathecal morphine dose. There was no difference between groups in nausea and vomiting, but pruritus increased in direct proportion to the dose of intrathecal morphine (linear regression, P = 0.0001). CONCLUSIONS: The dose of 0.1 mg intrathecal morphine produces analgesia comparable with doses as high as 0.4 mg, with significantly less pruritus when combined with low-dose bupivacaine.

RESUMEN

OBJECTIVES: We investigated mean platelet volume (MPV) in patients with slow coronary flow (SCF) and its possible relationship with clinical presentation. STUDY DESIGN: The study included 50 patients with SCF and otherwise normal coronary arteries and 22 patients (control group) with normal coronary arteries. In the SCF group, there were 26 patients with stable angina pectoris (SAP), and 24 patients with unstable angina pectoris (USAP). Coronary blood flow was measured using the TIMI frame count. To determine MPV, blood samples with K3 EDTA were processed after one hour of venipuncture. The relationship between MPV and SCF was sought. RESULTS: The mean TIMI frame count was markedly increased in patients with SCF compared to controls (p<0.0001). No significant differences existed between the groups with regard to white blood cell and platelet counts. Patients with SCF had significantly higher MPV values compared to controls (9.4+/-2.3 fl vs 8.1+/-2.0 fl, p=0.014). In subgroup analysis, MPV was significantly increased only in patients presenting with USAP, compared to patients with SAP (p=0.044) and controls (p=0.002). There was a positive correlation between the mean TIMI frame count and MPV in patients with SCF (r=0.32, p=0.01). In multivariate analysis, MPV was the only independent predictor of SCF (p=0.006, odds ratio=1.305, 95% CI=0.985-1.730). CONCLUSION: Our findings show that MPV is increased in patients with SCF, and SCF patients presenting with USAP exhibit significantly increased MPV values, suggesting an altered platelet reactivity and aggregation which may require effective anti-platelet therapy in this patient subgroup.

RESUMEN

In contrast to ST-elevation myocardial infarction treatment, there is no clear definition for when and which patient to discharge. Our study's main goal was to test the hypothesis that an early discharge strategy (within 48 to 56 hours) in patients with successful primary percutaneous coronary intervention (PPCI) is as safe as in patients who stay longer. The Early Discharge after Primary Percutaneous Coronary Intervention trial was designed in a prospective, randomized, multicenter fashion and registered with http://clinicaltrials.gov (NCT01860079). Of 900 patients with ST-elevation myocardial infarction, the study randomized 769 eligible patients to the early or the standard discharge group. The study's primary outcomes were all-cause mortality and readmission at 30 days. We considered assessment of functional status and health-related quality of life to be secondary outcomes. The early discharge group had significantly shorter length of hospital stay compared with the standard discharge group (45.99 ± 9.12 vs 114.87 ± 63.53 hours; p <0.0001). Neither all-cause mortality nor readmissions were different between the 2 study groups (p = 0.684 and p = 0.061, respectively). Quality-of-life measures were not statistically different between the 2 study groups. Our study reveals that discharge within 48 to 56 hours after successful PPCI is feasible, safe, and does not increase the 30-day readmission rate. Moreover, the patients perceived health status at 30 days did not differ with early discharge.

RESUMEN

OBJECTIVE: The aim of this study was to assess subclinical left (LV) and right ventricular (RV) dysfunction novel load-independent isovolumic myocardial acceleration (IVA) derived from tissue Doppler imaging (TDI) in patient with metabolic syndrome (MetS). METHODS: This study had an observational case-control design. The study included 133 subjects which were divided into two groups: 75 patients with MetS and 58 controls without MetS. MetS was defined by the presence of ≥3 criteria according to ATP-NCEP III guidelines. All the subjects underwent laboratory blood tests and complete conventional echocardiography and TDI. Student's t, Mann-Whitney U, Pearson's, and multiple regression analysis were used for statistical analysis. RESULTS: There were no significant difference between two groups in terms of traditional echocardiographic parameters. The diastolic and global functions of both ventricles were significantly impaired in MetS group. The TDI-derived IVA of the LV and the RV was significantly lower in patients with MetS (3.2±0.9 vs. 4.0±1.4, p<0.001 and 2.6±0.7 vs. 3.1±0.9, p=0.001, respectively). Whereas, TDI derived systolic velocity (Sa), and peak myocardial velocity during isovolumic contraction (IVV) of both ventricles were similar between the two groups. In the multiple regression analysis, waist circumference and diastolic blood pressure were found to be an independent determinant of IVA of LV (b=-.223, 95% CI=-.034 -.002, p=0.004) and RV (b=-.527, 95% CI=-.085 -.020, p=0.002) respectively. CONCLUSION: MetS affects global, diastolic, and systolic functions of two ventricles. This disruption lead to decreased function of heart was related with raised risk factors of MetS.

RESUMEN

The aim of this study was to evaluate the prevalence of aspirin resistance (AR) in patients undergoing hemodialysis (HD) and to assess the effect of HD on the results of the Multiplate test. A total of 54 patients undergoing HD were included in this study. Blood samples were taken just before and after the HD session. To determine AR, we used Multiplate test. Platelet aggregation values of the study population were 363.01 ± 225.69 aggregation unit (AU) × minutes before and 375.33 ± 254.05 AU × minutes after the HD (P = .597). There was strong correlation between the values before and after HD (R = .755, P < .0001). The AR status was changed in 9 (16.6%) patients after HD. Agreement of AR status before and after HD was substantial (κ coefficient = .667, P < .0001). The prevalence of AR in patients undergoing HD seems higher than in most of the studied populations, and this study has shown that the AR statuses of a significant number of patients undergoing HD change after an HD session.

RESUMEN

We sought to determine the prognostic value of neutrophil to lymphocyte ratio (NLR) in non-ST elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP). A total of 308 (mean age 59.22 ± 11.93) patients with NSTEMI and UAP were prospectively evaluated. The study population was divided into tertiles based on admission NLR values. The patients were followed for clinical outcomes for up to 3 years after discharge. In the Kaplan-Meier survival analysis, 3-year mortality was 21.6% in patients with high NLR versus 3% in the low-NLR group (P < .001). In a receiver-operating characteristic curve analysis, an NLR value of 3.04 was identified as an effective cut point in NSTEMI and UAP of a 3-year cardiovascular mortality (area under curve [AUC] = 0.86, 95% confidence interval [CI] 0.8-0.92). An NLR value >3.04 yielded a sensitivity of 79% and specificity of 71%. Admission NLR is the strong and independent predictor of a 3-year cardiovascular mortality in patients with NSTEMI and UAP.
