A Double Rarity: Lost intravascular Catheter Guidewire in Persistent Left Superior Vena Cava and Coronary Sinus - A Case Report.

Guidewire loss is a rare complication of central venous catheterization. A 65-year-old male was hospitalized in a high-dependency unit for exacerbation of chronic obstructive pulmonary disease, pneumonia, erythrocytosis, and clinical signs of heart failure. Upon admission, after an unsuccessful right jugular approach, a left jugular central venous catheter was placed. The next day, chest radiography revealed the catheter located in the left parasternal region, with suspected retention of the guidewire, visually confirmed by the presence of its proximal end inside the catheter. The left parasternal location of the catheter and the typical projection of the guidewire in the coronary sinus, later confirmed by echocardiography, raised suspicion of a persistent left superior vena cava (PLSVC). Agitated saline injected into the left antecubital vein confirmed bubble entry from the coronary sinus into the right atrium. After clamping the guidewire, the catheter was carefully retrieved along with the guidewire without any complications. This is the first reported case of guidewire retention in PLSVC and coronary sinus. It underscores the potential causes of guidewire loss and advocates preventive measures to avoid this potentially fatal complication.

32-year-old Traumatic Arteriovenous Fistula Presenting With Leg Ulcer and High-output Heart Failure.

Traumatic arteriovenous fistula (AVF) is not a common disorder, and dermatological signs and heart failure caused by AVF are rarely reported. We present the case of a 55-year-old woman who was referred for congestive heart failure symptoms. Echocardiography revealed preserved left ventricular ejection fraction. Due to edema of the right leg with a long-standing leg ulcer and palpable femoral thrill, duplex ultrasonography was performed. It showed an AVF between the right superficial femoral artery (SFA) and the right femoral vein (FV). The patient recalled a 32-year-old gunshot injury that was not medically treated. After the diagnosis of AVF she was referred to a surgeon for an AVF ligation, with subsequent resolution of her symptoms. The differential diagnosis of leg ulcer with leg edema should include the possibility of AVF as a cause.

Effects of Zofenopril on Arterial Stiffness in Hypertension Patients.

Angiotensin-converting enzyme inhibitors (ACEIs) reduce arterial stiffness beyond their antihypertensive effect. Studies showed that sulfhydryl ACEIs have the antioxidative potential to improve endothelial function, which might have a clinical effect on arterial distensibility. However, there are no studies that directly compare the effects of sulfhydryl (zofenopril) and non-sulfhydryl ACEIs (enalapril) on arterial stiffness. Therefore, this prospective study aims to compare the effects of enalapril and zofenopril on arterial stiffness and oxidative stress in both short- and long-term treatment of arterial hypertension (AH). Baseline and post-treatment peripheral and central arterial pressure indices, augmentation index (Aix), aortic pulse wave velocity (ao-PWV), serum levels of oxidized low-density cholesterol lipoprotein, LDL and uric acid (UA) were measured. The results showed that acute treatment with zofenopril, in contrast to enalapril, significantly decreased peripheral and central Aix (p < 0.001). Chronic treatment with zofenopril showed a superior effect over enalapril on the reduction of the peripheral systolic arterial pressure with reduction of ao-PWV (p = 0.004), as well as a reduction in peripheral Aix (p = 0.021) and central Aix (p = 0.021). Therefore, this study indicates that zofenopril has beneficial effects on the reduction of arterial stiffness compared to enalapril. It has potent clinical efficacy in AH treatment and further studies should compare its safety and long-term efficacy to other AH drugs that would aid clinicians in treating AH and other various cardiovascular diseases that have arterial stiffness as a common denominator.

Effect of Diabetic Neuropathy on Reparative Ability and Immune Response System.

The effects of diabetes can be divided into short, medium and long term and various human organ systems can be effected. The present study aimed to determine how much the duration of diabetes mellitus (DM) affect the reparative ability of the body, immune response and the development of DM complications. Interleukin 1-ß (IL-1ß) and Interleukin 6 (IL-6) were monitored as specific indicators of inflammatory reaction and C-reactive protein (CRP), leukocyte count (WBC) and sedimentation rate (ESR) as general markers of inflammatory reaction. Tumour necrosis factor α (TNF-α) and transforming growth factor ß1 (TGF-ß1) were observed as indicators of reparative ability and polyneuropathy. All interleukins were determined by ELISA and evaluated spectrophotometrically. Michigan Neuropathy Screening Instrument (MNSI) is performed for neuropathy examination. Patients with diabetes mellitus were divided into 3 groups, according to duration of diabetes mellitus. IL-6 levels correlated with clinical stage of diabetic polyneuropathy at p = 0.025 R = 0.402; with CRP at p = 0.0001, R = 0.784 as well as correlation of CRP and MNSI score (R = 0.500, p = 0.034) in a group of patients with DM lasting up to 10 years. The reparative ability of the body is reduced by physiological age and ages of DM duration. The immune response is weakened in DM additionally. The dual activity of cytokines IL-6 and TGF-ß1 is present in long-duration Diabetes Mellitus.

Prevalence, characteristics and prognostic impact of aortic valve disease in patients with heart failure and reduced, mildly reduced, and preserved ejection fraction: An analysis of the ESC Heart Failure Long-Term Registry.

AIMS: To assess the prevalence, clinical characteristics, and outcomes of patients with heart failure (HF) with or without moderate to severe aortic valve disease (AVD) (aortic stenosis [AS], aortic regurgitation [AR], mixed AVD [MAVD]). METHODS AND RESULTS: Data from the prospective ESC HFA EORP HF Long-Term Registry including both chronic and acute HF were analysed. Of 15 216 patients with HF (62.5% with reduced ejection fraction, HFrEF; 14.0% with mildly reduced ejection fraction, HFmrEF; 23.5% with preserved ejection fraction, HFpEF), 706 patients (4.6%) had AR, 648 (4.3%) AS and 234 (1.5%) MAVD. The prevalence of AS, AR and MAVD was 6%, 8%, and 3% in HFpEF, 6%, 3%, and 2% in HFmrEF and 4%, 3%, and 1% in HFrEF. The strongest associations were observed for age and HFpEF with AS, and for left ventricular end-diastolic diameter with AR. AS (adjusted hazard ratio [HR] 1.43, 95% confidence interval [CI] 1.23-1.67), and MAVD (adjusted HR 1.37, 95% CI 1.07-1.74) but not AR (adjusted HR 1.13, 95% CI 0.96-1.33) were independently associated with the 12-month composite outcome of cardiovascular death and HF hospitalization. The associations between AS and the composite outcome were observed regardless of ejection fraction category. CONCLUSIONS: In the ESC HFA EORP HF Long-Term Registry, one in 10 patients with HF had AVD, with AS and MAVD being especially common in HFpEF and AR being similarly distributed across all ejection fraction categories. AS and MAVD, but not AR, were independently associated with increased risk of in-hospital mortality and 12-month composite outcome, regardless of ejection fraction category.

High-output heart failure following gunshot injury and traumatic arteriovenous fistula.

BACKGROUND: Heart failure due to high cardiac output rarely occurs. Few cases of post-traumatic arteriovenous fistula (AVF) as a cause of high-output failure were reported in the literature. METHODS: Herein, we report a case of 33-year-old male who was admitted to our institution due to symptoms of heart failure. He reported a gunshot injury of the left thigh 4 months earlier, when he had been shortly hospitalized and discharged 4 days later. Since the gunshot injury he had exertional dyspnea and left leg edema, so the diagnostic procedures were performed. RESULTS: Clinical examination revealed distended neck veins, tachycardia, slightly palpable liver, left leg edema, and thrill over the left thigh. Due to high clinical suspicion, duplex ultrasonography of the left leg was performed that verified femoral AVF. Operative treatment of AVF was made with prompt resolution of symptoms. CONCLUSIONS: This case wants to emphasize the importance of proper clinical examination, and duplex ultrasonography in all cases of penetrating injuries.
