RESUMO

BACKGROUND: Relation of plasma fibrinogen levels with extent, severity, and complexity of coronary artery disease (CAD) in patients with stable angina pectoris (SAP) has not been adequately investigated. The aim of this study was to evaluate whether plasma fibrinogen level is associated with coronary complexity, severity, and extent assessed by SYNTAX (Synergy between percutaneous coronary intervention with TAXUS and Cardiac Surgery) score (SS). METHODS: We enrolled 134 consecutive patients with SAP who underwent coronary angiography. Baseline serum fibrinogen levels were measured, and SS was calculated from the study population. The patients were classified into 3 groups by tertiles of SS (SS, control group = 0; intermediate group < 22; and high group ≥ 22). RESULTS: Plasma fibrinogen levels demonstrated a stepwise increase from control group to high SS group. There was a strong correlation between fibrinogen and the SS ( r = .535, P < .001). Area under the receivers operating characteristic curve of fibrinogen was 0.72 (95% confidence interval [CI] 0.61-0.82; < .001) for predicting a high SS. Fibrinogen value higher than 411 mg/dL has a sensitivity of 75% and a specificity of 64% in prediction of high SS. In multivariate analyses, plasma fibrinogen was observed to be an independent predictor for high SS in patients with stable CAD (odds ratio [OR] 1.01; 95% CI, 1.01-1.02; P < .001). CONCLUSION: Plasma fibrinogen is a readily measurable systemic inflammatory marker and is independently associated coronary severity and complexity in patients with CAD.

RESUMO

The fastest growing demographic group in Europe and America is the elderly, and significant mitral regurgitation is very prevalent in this population. At present, with mitral valve surgery in elderly individuals gaining greater acceptance worldwide, the question whether to repair or replace the valve remains controversial. Recent studies have demonstrated the safety, feasibility, and durability of repair over replacement in elderly patients. Herein, we report the case of an elderly patient who underwent surgical re-interventions on the mitral valve following an unsuccessful mitral valve repair procedure.

RESUMO

BACKGROUND: The goal of this study was to determine changes in left atrial (LA) function with two-dimensional speckle tracking echocardiography (2DSTE) and real-time full-volume three-dimensional echocardiography (RT3DE) after percutaneous mitral valve repair with the MitraClip system. Furthermore, we investigated whether baseline and/or changes in LA function after MitraClip repair had any impact on prognosis. METHODS: A total of 25 consecutive patients (age: 57±12 years, 76% male) with moderate-to-severe or severe mitral regurgitation (MR) were included. Patients underwent 2DSTE and RT3DE before the clip implantation and after the 12-month follow-up. Prognostic data were also recorded via the use of telephone calls and follow-up visits for 12 months after the procedure. RESULTS: Compared with the baseline, the LA reservoir strain (LA-Res) (7.66±4.3% vs 11.15±7.5%, P<.001) and LA contraction strain (LA-Pump) (4.64±4.3% vs 7.63±5.8%, P=.001) improved significantly after MitraClip repair; significant improvements were also seen in three-dimensional (3D) minimum LA volume index (LAV min) and maximum LA volume index (LAV max). On the other hand, conventional LA indices did not change. In total, eleven major adverse cardiac events (MACE) were observed at the 1-year follow-up. In univariate analyses, the preprocedural echocardiographic parameters that were associated with the MACE within 1 year after MitraClip repair were 3D-LAV min and LA-Res. Furthermore, these indices significantly correlated with improved functional parameters and MR reduction. CONCLUSION: In conclusion, a successful MitraClip procedure can reverse the process of LA remodeling within 12 months, and this can be detected by 2DSTE and RT3DE. Also, patients with preprocedural lower LA-Res and higher 3D-LAV min had the worst prognoses at the 1-year follow-up.

RESUMO

BACKGROUND: Right ventricular (RV) effects of long-term use of anabolic-androgenic steroids (AAS) are not clearly known. The aim of this study was to assess RV systolic functions by two-dimensional speckle tracking echocardiography (2DSTE) in AAS user and nonuser bodybuilders. METHODS: A total of 33 competitive male bodybuilders (15 AAS users, 18 AAS nonusers) were assessed. To assess RV systolic functions, all participants underwent standard two-dimensional and Doppler echocardiography, and 2DSTE. RESULTS: Interventricular septal thickness, left ventricle posterior wall thickness, relative wall thickness, and left ventricle mass index were significantly higher in AAS users than nonusers. While standard diastolic parameters were not statistically different between the groups, tissue Doppler parameters including RV E' and E'/A' were lower in AAS users than nonusers (10.1 ± 2.0 vs. 12.7 ± 2.1; P = 0.001, 1.1 ± 0.1 vs. 1.5 ± 0.4; P = 0.009, respectively). Tricuspid annular plane systolic excursion, RV fractional area change, and RV S' were in normal ranges. However, RV S' was found to be lower in users than nonusers (12.2 ± 2.2 vs. 14.6 ± 2.8, P = 0.011). RV free wall longitudinal strain and strain rate were decreased in AAS users in comparison with nonusers (-20.2 ± 3.1 vs. -23.3 ± 3.5; P = 0.012, -3.2 ± 0.1 vs. -3.4 ± 0.1; P = 0.022, respectively). In addition, there were good correlations between 2DSTE parameters and RV S', E', and E'/A'. CONCLUSION: Despite normal standard systolic echo parameters, peak systolic RV free wall strain and strain rate were reduced in AAS user bodybuilders in comparison with nonusers. Strain and strain rate by 2DSTE may be useful for early determination of subclinical RV dysfunction in AAS user bodybuilders.

RESUMO

In patients with mammary-coronary bypass grafts, the presence of a subclavian artery stenosis proximal to the internal mammary artery may result in a condition termed coronary-subclavian steal syndrome of which the incidence varies between 0.07-3.4% among those requiring coronary grafts. We reported a patient with a history of the coronary artery bypass graft who presented with typical angina pectoris at rest that was exacerbated by selective exercise of the left upper extremity in whom occlusion of the left subclavian artery was demonstrated in this patient by 3D reconstruction of computed tomography angiography, a reversal blood flow in the left internal mammary artery-left anterior descending artery graft by Doppler ultrasonography, and a coronary angiography.

RESUMO

Eustachian valve (EV) is a vestige of the valve of the inferior vena cava which directs the umbilical vein blood through open foramen ovale in fetal life. Following birth it gradually regresses, but it may persist in variable size, shape, and thickness as a functionless and benign structure. However, there are reports suggesting that persistent EV may not be completely innocent. It has been accused of being a predisposing cause of patent foramen ovale and paradoxical embolism and also interfering with transseptal interventional procedures. It may serve as a site of infective vegetations and be mistaken as a tumor or thrombus. In the present case, an octopus-like thrombus attached to the EV was delineated with the utility of two-dimensional and real time three-dimensional transesophageal echocardiography. EV was considered to play an essential role in preventing potential pulmonary embolism.

RESUMO

Myocardial metastasis from oesophageal cancer is very rare, and is usually detected as part of widespread metastases in the terminal stage. It is rare to detect a solitary metastasis. We present a case of solitary myocardial metastasis from distal oesophagus complicated by ventricular fibrillation.
