Initial experience on cardiac magnetic resonance-aided VT ablation in South America.

Background: Cardiac magnetic resonance (CMR) allowed to precisely identify the substrate in scar-related ventricular tachycardia (VT). New software has been developed to define the 3D scar and corridors to help VT ablation by integrating the scar and electroanatomical mapping (EAM). The objective of this study is to evaluate the results of VT ablation aided by the integration of EAM and CMR software processed scar.

Management of massive hemopericardium in the electrophysiology laboratory: The double long sheath technique.

To describe a simple and useful technique for acute management of massive hemopericardium inside the Electrophysiology (EP) laboratory METHODS AND RESULTS: Five patients from a single center experience were identified, all with blood loss above 1000 ml after initial pericardiocenthesis. Using two long 8.5 F transseptal sheaths inside the pericardium space, with continuous negative pressure, allowed the complete cessation of bleeding or hemodynamic maintenance until definitive surgical repair in all patients CONCLUSION: The use of two long sheaths for blood drainage, instead of conventional pericardiocenthesis, might be helpful to manage massive hemopericardium inside EP lab, avoiding urgent cardiac surgery or maintaining clinical stability until surgical staff is available.

CULPRIT-SHOCK study.

The treatment of patients with ST-segment elevation myocardial infarction concomitant with the presence of multivessel disease has been studied in several recent studies with the purpose of defining the need, as well as the best moment to approach residual lesions. However, such studies included only stable patients. The best therapeutic approach to cardiogenic shock secondary to acute coronary syndrome, however, remains controversial, but there are recommendations from specialists for revascularization that include non-event related injuries.

Self-report of psychological symptoms in hypoparathyroidism patients on conventional therapy.

Objective: Hypoparathyroidism is characterized by parathyroid hormone deficiency and hypocalcemia. It has been demonstrated that these patients may also present psychiatric symptoms and decrease of quality of life. The aims of this study were to evaluate the presence of psychopathological symptoms in a cohort of patients with hypoparathyroidism and compare to a control group.

Hypoparathyroidism and pseudohypoparathyroidism: etiology, laboratory features and complications.

Objectives: To identify a clinical profile and laboratory findings of a cohort of hypoparathyroidism patients and determine the prevalence and predictors for renal abnormalities.

Materials And Methods: Data from medical records of five different visits were obtained, focusing on therapeutic doses of calcium and vitamin D, on laboratory tests and renal ultrasonography (USG).

Results: Fifty-five patients were identified, 42 females and 13 males; mean age of 44.

Prevention of Capsular Contracture Using Leukotriene Antagonists.

Background: Capsular contracture is a common occurrence in plastic surgery, with a prevalence varying from 0.5 percent up to 30 percent. Although the standard treatment is capsulectomy, alternative treatments have been studied, such as the use of leukotriene inhibitors.
