  1. Mesalamine-induced myocarditis following diagnosis of Crohn's disease: a case report

    Galvão-Braga, C; Martins, J; Arantes, C; Ramos, V; Vieira, C; Salgado, A; Magalhães, S; Correia, A
    Mesalamine is a common treatment for Crohn's disease, and can be rarely associated with myocarditis through a mechanism of drug hypersensitivity. We present the case of a 19-year-old male who developed chest pain two weeks after beginning mesalamine therapy. The electrocardiogram showed slight ST-segment elevation with upward concavity in the inferolateral leads; blood tests demonstrated elevated troponin I and the echocardiogram revealed moderately depressed left ventricular systolic function with global hypocontractility. Cardiac magnetic resonance imaging confirmed the diagnosis of myocarditis, revealing multiple areas of subepicardial fibrosis. The onset of symptoms after mesalamine, and improvement of chest pain, cardiac biomarkers and...

  2. Role of central obesity in risk stratification after an acute coronary event: Does central obesity add prognostic value to the Global Registry of Acute Coronary Events (GRACE) risk score in patients with acute coronary syndrome?

    Martins, A; Ribeiro, S; Gonçalves, P; Correia, A
    BACKGROUND: Accurate risk stratification is an important step in the initial management of acute coronary syndrome (ACS), and current guidelines recommend the use of risk scores, such as the Global Registry of Acute Coronary Events risk score (GRACE RS). Recent studies have suggested that abdominal obesity is associated with cardiovascular events in patients with ACS. However, little is known about the additional value of abdominal obesity beyond risk scores. The aim of our study was thus to assess whether waist circumference, a surrogate of abdominal adiposity, adds prognostic information to the GRACE RS. METHODS: This was a retrospective cohort study of ACS patients...

  3. Anomalous coronary origin: From suspicion to surgical revascularization

    Vieira, C; Nabais, S; Salgado, A; Salomé, N; Sousa, P; Madureira, AJ; Pinho, P
    Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leading to suspicion of compression by the pulmonary artery, confirmed by CT angiography. The patient underwent surgical revascularization with a good result. The authors highlight the need to consider compression of an anomalous coronary artery by the pulmonary artery in the differential diagnosis...

  4. Stroke and Cardiac Papillary Fibroelastoma: Mechanical Thrombectomy after Thrombolytic Therapy

    Santos, AF; Pinho, J; Ramos, V; Pardal, F; Rocha, J; Ferreira, C
    We describe a case of a 34-year-old man with a sudden development of right hemiparesis and aphasia because of infarction of the left middle cerebral artery that was submitted to intravenous (IV) recombinant tissue plasminogen activator and mechanical thrombectomy. Transesophageal echocardiogram showed a small mass on the anterior leaflet of the mitral valve. Cardiac surgery was performed, and histological examination of the removed material was consistent with cardiac papillary fibroelastoma (CPF). Experience in using IV thrombolysis for the treatment of embolic stroke because of CPF is limited. To the best of our knowledge, only 3 patients are reported in literature...

  5. Caseous calcification of the mitral annulus: A multi-modality imaging perspective

    Ribeiro, S; Salgado, A; Salomé, N; Bettencourt, N; Azevedo, P; Costeira, A; Correia, A
    Mitral annulus calcification is a common echocardiographic finding, particularly in the elderly and in end-stage renal disease patients under chronic dialysis. Caseous calcification or liquefaction necrosis of mitral annulus calcification is a rare evolution of mitral annular calcification. Early recognition of this entity avoids an invasive diagnostic approach, since it is benign and, unlike intracardiac tumors and abscesses, has a favorable prognosis. The authors present the case of an 84-year-old woman with a suspicious large, echodense mass at the level of the posterior mitral leaflet with associated severe mitral regurgitation. Cardiac magnetic resonance imaging demonstrated a hypoperfused mass with strong...

  6. Takotsubo cardiomyopathy: a rare, but serious, complication of epileptic seizures

    Rocha, J; Gonçalves, E; Vieira, C; Almeida, F; Pereira, J

  7. A rare cause of pericardial disease

    Ramos, V; Vieira, C; Fernandes, N; Nunes-Gonçalves, N; Salgado, A; Correia, A
    Among cardiovascular diseases, pericardial disease has specific characteristics. Its etiology, diagnosis and medical management are not as well understood as in coronary and valvular heart disease. In most cases, its cause is benign, although the proportion decreases with more severe clinical presentation. The authors present the case of a 35-year-old man with no relevant past medical history, who went to the emergency department with what appeared to be an idiopathic case of acute pericarditis. However, over the following five months, there was an unfavorable evolution to constrictive pericarditis, requiring pericardiectomy. The final diagnosis was only made following surgery - a...

  8. Ischemic rupture of the anterolateral papillary muscle

    Vieira, C; Gaspar, A; Álvares-Pereira, M; Salomé, N; Almeida, J; Amorim, MJ
    We describe the case of a 59-year-old man who presented with chest pain and ST-segment elevation in the inferior leads, R>S in V1 and ST depression in the anterior leads due to proximal occlusion of the first obtuse marginal. Primary coronary angioplasty and stenting of this artery were performed. Twelve hours later the patient became hemodynamically unstable and severe mitral regurgitation due to rupture of one of the heads of the anterolateral papillary muscle was diagnosed. Emergency surgery was performed (papillary muscle head reimplantation, mitral annuloplasty with a rigid ring, tricuspid annuloplasty and coronary artery bypass grafting). On surgical inspection,...

  11. Non-coronary sinus of Valsalva aneurysm diagnosed after a road traffic accident

    Ribeiro, A; Fernandes, F; Costeira, A; Simões, A; Rodrigues, P
    A 38 year old man with a huge unruptured sinus of Valsalva aneurysm, complicated with severe valvar aortic regurgitation, is described. The aneurysm was detected by echocardiography in the asymptomatic patient who presented with an intense precordial diastolic rumble after a road traffic accident. The patient had successful surgery for the aneurysm and aortic valve replacement. Possible aetiologies for the aneurysm and a brief revision of clinical aspects and treatment are discussed.

  12. Chest stab wound: a rare cause of late ventricular tachycardia

    Ribeiro, S; Salomé, N; Pinho, T; Gonçalves, H; Primo, J; Azevedo, P; Correia, A

  13. Endocardite fúngica com embolização central e periférica: um caso clínico

    Ribeiro, S; Gaspar, A; Assunção, A; Torres, JP; Azevedo, P; Basto, L; Pinho, P; Correia, A
    A 50-year-old man with a history of drug addiction was admitted to the cardiology department for aortic valve fungal endocarditis complicated by severe aortic regurgitation, cerebral infarcts and right common iliac artery pseudoaneurysm. While awaiting transfer to the cardiothoracic surgery department, the patient presented acute arterial ischemia of the left leg, and distal left patellofemoral embolectomy was successfully performed. The patient was then transferred to the cardiothoracic center and the aortic valve was replaced by a bioprosthetic valve. After fourteen days he was referred for vascular surgery, where the four-month hospitalization was complicated by left leg amputation. Four months after...

  15. Sudden death and variant angina

    Costa, J; Pereira, MA; Correia, A; Rebelo, A; Araúlo, AO
    Variant angina is defined by chest pain occurring at rest associated with transitory ST segment elevation on ECG, and is caused by a spasm of a coronary artery. Frequently, variant angina is associated with atherosclerotic coronary obstruction and patients with normal coronary arteries are rare. Patients with variant angina and normal coronary arteries have good prognosis, and the development of ventricular arrhythmias or sudden death is rare. The authors present two cases of sudden cardiac death in patients with variant angina and normal coronary arteries.

  16. Congenitally corrected transposition of the great arteries and aortic coarctation--an uncommon association

    Brandão, A; Magalhães, S; Correia, A
    Congenitally corrected transposition of the great arteries, L-TGA, is a rare abnormality accounting for less than 0.5% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate are variable and depend mostly on associated anomalies. The authors present a clinical case of a twenty-four-year-old woman in whom, in a routine echocardiogram, congenitally corrected transposition of the great arteries and aortic coarctation were diagnosed, an unusual association. They describe the results of complementary exams (echocardiography, chest X-ray, electrocardiogram and cardiac angiography) that they believe to be useful for the correct diagnosis of this clinical situation. Additionally, the...

  17. Associação entre o índice de anisocitose (RDW) e a ocorrência de morte ou enfarte aos seis meses em doentes com síndrome coronária aguda

    Nabais, S; Losa, N; Gaspar, A; Rocha, N; Costa, J; Azevedo, P; Basto, L; Pereira, MA; Correia, A
    BACKGROUND: Higher values of red ceildistribution width (RDW) may be associated with adverse outcomes in patients with heart failure and in those with stable coronary artery disease. We assessed the hypothesis that higher RDW values are associated with adverse cardiovascular outcomes in patients with acute coronary syndromes (ACS). METHODS: We studied 1796 patients with ACS admitted to a coronary care unit. We analyzed clinical and laboratory characteristics, management, and outcomes of patients according to tertiles of baseline RDW. The primary outcome was death or myocardial infarction (MI) during six-month follow-up. RESULTS: Patients with higher RDW values tended to be older, were more likely to be...
