RESUMO

BACKGROUND: Spontaneous coronary artery dissection is a rare and important cause of myocardial infarction, especially in young women without other coronary artery disease. This arterial dissection can occur within or between any of the 3 layers. Its predisposing factors include connective tissue diseases (Marfone syndrome, Ehlers-Danlos syndrome), vasculitis (polyarteritis nodosa, systemic lupus erythematosus, and Kawasaki disease), atherosclerosis and fibromuscular dysplasia. Clinical presentations of spontaneous coronary artery dissection are wide spectrum from asymptomatic to acute coronary disease, sustained ventricular arrhythmia and sudden cardiac death. CASE PRESENTATION: We describe A 33-year-old man with history of Hodgkin's lymphoma five years earlier that became a candidate for Patent foramen ovale closure due to recurrent embolic cerebrovascular accident. Before the intervention, coronary angiography incidentally showed dissection in the left main and all major coronary arteries. CONCLUSIONS: Based on our hypothesis, chemoradiotherapy-induced arteriopathies could be consider as a predisposing factor for spontaneous coronary artery dissection.

RESUMO

BACKGROUND: Accelerated idioventricular rhythm (AIVR) is a slow ventricular arrhythmia, commonly due to myocardial ischemia in coronary artery disease. It is a transitory rhythm that rarely causes hemodynamic instability or necessitates any specific therapy. Besides, the common predisposing factors for ventricular arrhythmias after open-heart surgery are hemodynamic instability, electrolyte imbalances, hypoxia, hypovolemia, myocardial ischemia and infarction, acute graft closure, reperfusion injury, and administration of inotropes and antiarrhythmic drugs. Here we report a case of AIVR after cardiac surgery, mostly due to hypothermia that to our knowledge, it is the first report. CASE PRESENTATION: We describe a 76-year-old man presenting with typical chest pain. Following routine investigations, the patient underwent coronary artery bypass grafting. Postoperatively, he was transferred to the intensive care unit with good hemodynamic status. However, about 3 h later, he developed rhythm disturbances, leading to hemodynamic instability without response to volume replacement or inotropic support. His rhythm was AIVR, although, at first glance, it resembled the left bundle branch block. Given his unstable hemodynamic status, he was emergently transferred to the operating room. Cardiopulmonary bypass (CPB) was resumed for hemodynamic support. After the patient was rewarmed to about 35 ºC, AIVR returned to normal. He was weaned from CPB successfully and with an uneventful hospital course. CONCLUSIONS: Hypothermia is a potential cause of rhythm disturbance. Preventing the causes of arrhythmias, including hypothermia, is the best strategy.

RESUMO

BACKGROUND: Alkaptonuria is a rare congenital metabolic disorder characterized by homogentisic acid accumulation in body cartilage and connective tissues due to a deficient homogentisic acid dioxygenase enzyme. This disorder manifests in various clinical symptoms, including spondyloarthropathy, ocular and dermal pigmentation, genitourinary tract obstruction by ochronosis stones, and cardiovascular system involvement. Cardiac ochronosis is a rare manifestation of alkaptonuria that may present as aortic stenosis, sometimes accompanied by other cardiovascular complications. CASE PRESENTATION: We report an unexpected case of ochronosis diagnosed during cardiac surgery. Due to the fragile, thin, and atheromatous nature of the ascending aorta in patients with ochronosis, we opted for a sutureless aortic valve replacement procedure. This approach appears to be more suitable for patients with ochronosis. CONCLUSIONS: Although cardiac ochronosis is rare, surgeons should remain vigilant and consider the possibility of this condition when examining patients with aortic valve stenosis, paying close attention to the clinical manifestations of alkaptonuria.

RESUMO

Cardiac valvular Ehlers-Danlos syndrome (EDS) (type IV) is a rare subtype of the syndrome. The progressive and severe involvement of the heart valves is the principal characteristic of cardiovascular EDS, hence the necessity of the screening of patients with EDS for possible cardiovascular complications. We herein describe a 17-year-old male patient, with a known case of Ehlers-Danlos syndrome, who was referred to our center due to symptomatic severe mitral regurgitation. Echocardiography showed the flailing of the A3 scallop of the mitral valve (MV) and severe enlargement of the left ventricle and the left atrium with mild systolic dysfunction. A physical examination revealed joint hyperlaxity, skin hyperelasticity, and abdominal hernias. He was, therefore, scheduled for surgery. MV repair was performed via commissuroplasty and ring annuloplasty, with an acceptable saline test. After being weaned from cardiopulmonary bypass, the patient had mild mitral regurgitation, which escalated to moderate-to-severe mitral within minutes. Consequently, the MV was replaced with a bioprosthetic valve. The postoperative course was uneventful. Due to the high fragility of the MV, any resection and sewing of its fragile leaflets may produce residual regurgitation and necessitate valve replacement. MV replacement may be more logical in such patients. Our patient's postoperative course was uneventful, and he was discharged without symptoms. Over 1 and 3 months of follow-up, he remained asymptomatic, and transthoracic echocardiography showed a normal bioprosthetic MV without paravalvular leakage.

RESUMO

Chronic kidney disease is a worldwide health problem. Type II diabetes mellitus is now a major cause of end stage renal disease. The effect of diabetes mellitus through the dysregulation of the innate immunity results in increased tumor necrosis factor-alpha. This can lead to an increasing protein trafficking through the glomerular capillary, which can have an intrinsic renal toxicity. Seventy-four patients with type II diabetes mellitus with overt proteinuria were included in the study. They were randomly assigned to two groups of 37 patients (group 1: captopril 25 mg three times a day, group 2: captopril 25 mg and pentoxifylline 400 mg each three times per day). In the course of the study, two patients were excluded from each group. Daily urinary protein excretion was assessed at baseline and at two and six months. The reduction of urinary protein to creatinine clearance ratio in group 2 was 15.16 points more than in group 1 from baseline to the end of the study (p = 0.001). The difference in reduction only started after two months of pentoxifylline use. The differences in HbA1c and duration of diabetes mellitus at baseline in the two groups had not adversely affected the outcome of the study. There was a modest decrease in systolic blood pressure in group 2 as well (p = 0.041). Combining an angiotensin-converting enzyme inhibitor and pentoxifylline can lead to a greater reduction in proteinuria.

RESUMO

Fungal endocarditis is a relatively rare condition which mostly complicates those with intra-cardiac devices and those whose immune system is compromised. Here we present a 63-year-old diabetic man with two-weeks history of weakness and fatigue plus low-grade fever. Transesophageal echocardiography showed a mobile mass attached to the left coronary cusp of the aortic valve which protruded into the left ventricular (LV) outflow tract. Cardiac magnetic resonance further confirmed the presence of a large broad base 18 × 20 × 18 mm mass without gadolinium enhancement suggestive for fungal infection. Voriconazole was administered on the same day after which distal embolization of the mass to distal abdominal aorta ensued shortly. Echocardiography documented the disappearance of the mass from LV outflow tract. Vascular surgeon removed the mass from abdominal aorta immediately and pathology revealed the aspergilloma which was later confirmed by culture. After embolization the patient had become unstable and signs of septic shock occurred which ultimately led to his death in 72 h. Presence of Aspergillus infection in apparently normal cardiac chambers without presence of any intra-cardiac device is extremely rare and the presented case study reports such a scenario. Rapid initiation of anti-fungal agents and early surgery are of paramount importance in patient survival. .

RESUMO

INTRODUCTION: Major Depressive Disorder (MDD) is known as one of the most common psychiatric disorders in patients with multiple sclerosis (MS). In recent years, zinc has been found to have beneficial effects on psychopathology and the therapy of depression. The aim of the present study was to examine the effect of zinc supplement on depression and neurological signs in patients with MS. METHODS: The present randomized, double-blind, placebo-controlled clinical trial was performed on 43 patients with MS and who also demonstrated MDD based on the Beck questionnaire. These patients were randomly selected and were divided into two groups: the placebo group (n=22) and the intervention group (n=21). The patients received either zinc sulphate (220 mg containing 50mg zinc element) or a placebo for 12 weeks. Clinical examinations were obtained in terms of abnormal ocular movement, muscle power, and gait disorder. RESULTS: The results indicated that in the patients who received the zinc supplement, the mean score of depression was reduced compared to those in the placebo group, whereas the neurological examinations revealed that there were no differences between the treatment and control groups. CONCLUSION: Therefore, the zinc supplementation is an appropriate choice for the depression management in patients with MS.

RESUMO

BACKGROUND: Contrast-induced nephropathy (CIN) is commonly encountered. Because the therapy of choice for prevention of CIN is controversial, in this study we compared the preventive efficacy of bicarbonate (Bi) infusion in dextrose water versus normal saline (NLS) infusion alone or in combination with oral acetazolamide (AZ). METHODS: In a double-blind and randomized clinical trial, all patients undergoing coronary angiography or percutaneous coronary intervention received NLS (NLS group), its combination with AZ (AZ group) or infusion of Bi (Bi group) before the procedures. RIFLE (risk of renal failure, injury to the kidney, failure of kidney function, loss of kidney function, and end-stage renal disease) criteria were used to define CIN-associated acute kidney injury (AKI). RESULTS: The risk of AKI in CIN was significantly lower in the Bi and AZ groups than in the NLS group (P 0.05). CONCLUSIONS: It seems that both Bi and AZ reduce the risk of CIN-related AKI, and close monitoring of serum potassium is needed during bicarbonate infusion.

RESUMO

Fungal infections of the central nervous system (CNS) are almost always a surprising finding. Their presentation is usually subtle, often without any diagnostic characteristics, and they are frequently mistaken for pyogenic abscesses, or brain tumors. Aspergillosis of the central nervous system is an uncommon infection, mainly occurring in immunocompromised patients. It may present in several forms, including meningitis, mycotic aneurysms, infarcts and a tumoral form. We report an intracranial granuloma due to Aspergillus fumigatus involving the anterior cranial fossa and the frontal lobe. The clinical symptoms began one year before admission. Final diagnosis was made after craniotomy. The patient was treated with an extensive excision of the cerebral mass and medical antifungal therapy (intravenous amphotericin B), but she failed to respond to these treatments and died.
