A rare case report of hypertrophic cardiomyopathy induced by catecholamine-producing tumor

RATIONALE: Catecholamine-producing tumors are rare, occurring in less than 0.2% of patients with hypertension, but can have relevant cardiovascular morbidity and mortality. PATIENT CONCERNS: A 37-year-old woman presented with a history of dyspnea, chest pain, palpitations, and paroxysmal hypertension. Electrocardiogram, echocardiogram, and cardiac magnetic resonance showed severe LVH with a prevalent involvement of the anterior portion of interventricular septum. Endomyocardial biopsy found severe hypertrophy with disarray of cardiomyocytes and ultrastructural evidence of contraction and necrosis of myocytes. Hormone investigations revealed high values of 24-hours urinary metanephrines. Abdominal computed tomography (CT) showed an enlarged left adrenal gland with a strong uptake of I-metaiodobenzylguanidine at scintigraphy scan. INTERVENTIONS:Thus, the adrenal tumor was surgically removed. OUTCOMES: At follow-up examination, the patient's metanephrines levels were normalized and the transthoracic echocardiogram showed a reduction of LVH. DIAGNOSIS AND LESSONS: We report a rare case of catecholamine-induced cardiomyopathy due to an adrenal adenoma mixed with nodules enriched in epinephrine-types secreting granules

Autoimmune Diseases in Patients with Cushing’s Syndrome after Resolution of Hypercortisolism: Case Reports and Literature Review

Introduction. Cushing’s syndrome (CS) is a clinical condition characterized by excessive cortisol production, associated with metabolic complications, such as diabetes mellitus, dyslipidemia, metabolic syndrome, hypertension, and cardiovascular diseases. Nowadays, the occurrence of autoimmune diseases in CS have not been completely evaluated in the previous studies. Objective. The aim of this study was to evaluate the occurrence of autoimmune diseases in CS patients after successfully treated. Materials and Methods. From January 2001 to December 2017, in our Secondary Hypertension Unit, we evaluated 147 CS patients (91 with ACTH-independent disease, 54 with ACTH-dependent disease, and 2 patients with ectopic ACTH production. Results. 109 CS patients (74.1%) were surgically treated (67 ACTH-independent CS patients (61.5%) undergone adrenalectomy and 42 ACTH-dependent CS (38.5%) undergone transsphenoidal surgery) and evaluated after 6, 12, and 24 months after clinical and biochemical remission of disease. In 9 (8.3%) of overall treated CS patients (8.3%), during follow-up, we observed the onset of some manifestations of autoimmune diseases. In particular, one patient had a systemic lupus erythematosus, one patient had rheumatoid arthritis, 4 patients reported autoimmune thyroiditis (Basedow-Graves’ disease and Hashimoto’s thyroiditis), one patient had clinical features of psoriasis, one patient showed myasthenia gravis, and one patient had giant cell arteritis. Conclusions. Our results demonstrate that patients successfully treated for CS could develop autoimmune diseases. Therefore, after treatment, CS patients need to be strictly monitored in order to evaluate the possible onset of autoimmune diseases

Minimally invasive aortic valve replacement with Perceval S sutureless valve: Early outcomes and one-year survival from two European centers

ObjectiveThe aim of our study was to evaluate the early outcomes and 1-year survival of patients undergoing minimally invasive aortic valve replacement with the Perceval S sutureless valve for severe aortic stenosis.MethodsFrom March 2010 to March 2013, 281 high-risk patients underwent minimally invasive aortic valve replacement with the Perceval S sutureless valve through either right anterior minithoracotomy (n = 164) or upper ministernotomy (n = 117) at 2 cardiac centers.ResultsThe overall in-hospital mortality was 0.7% (2 patients). The overall median cardiopulmonary bypass and crossclamp time was 81 minutes (interquartile range, 68-98) and 48 minutes (interquartile range, 37-60), respectively. Postoperative stroke occurred in 5 patients (1.8%). The incidence of paravalvular leak greater than 1 of 4 and atrioventricular block requiring pacemaker implantation was 1.8% (5 patients) and 4.2% (12 patients), respectively. No migration occurred, and the mean postoperative gradient was 13 ± 4 mm Hg. At a median follow-up of 8 months (interquartile range, 4-14), the overall survival was 90%.ConclusionsMinimally invasive aortic valve replacement with the Perceval S sutureless valve in high-risk patients is a safe and reproducible procedure associated with excellent hemodynamic results, postoperative outcomes, and 1-year survival
