ABSTRACT: We present the case of a 49-year-old male patient with prosthetic mitral valve endocarditis associated with QT prolongation and torsades de pointes. He was asymptomatic until the end of January 2012, when he was admitted to our hospital emergency unit because of syncope, fever, and suspicion of endocarditis. Cardiologic evaluation was requested and the transthoracic (TTE) and transesophageal (TEE) echocardiograms revealed vegetations on the prosthetic mitral valve. All cultures were positive for methicillin-sensitive Staphylococcus aureus. The corrected QT (QTc) interval was markedly prolonged upon admission (QTc 540 ms). He experienced torsades de pointes (TdP) several times and he was recovered after bystander cardiopulmonary resuscitation. The clinical course and the long QTc interval with deep inverted T wave were completely normalized 4 weeks after. He continued on triple antibiotic therapy for 45 days with a good revolution. The clinical features and the possible mechanisms of QT prolongation (inflammation, infection) of this patient are discussed.

ABSTRACT: Supraventricular tachycardia in infants are variable. We try to summarize clinical, electrical and treatment particularities of supraventricular arrhythmia in infants. The majority of infants with supraventricular arrhythmia have a good clinical outcome and an excellent prognosis and may not require chronic antiarrhythmic therapy if they had precocious treatment.

ABSTRACT: To study the epidemiologic, clinical, therapeutic and prognostic characteristics of the myocardial infarction (MI) in patients with chronic kidney disease (CKD). To identify the impact of CKD in hospital, mid- and long-term survival after myocardial infarction. To determine the predictive factors of hospital and midterm MACCE in patients with CKD.
The study population was 231 patients with a myocardial infarction admitted alive from January 2005 to December 2006. The population was divided into two groups. Group 1: glomerular filtration rate (GFR) ≥60 ml/min: 112 patients; group 2: GFR<60 ml/min: 119 patients.
Patients with CKD had more history of stroke and arterial hypertension. They had received less medical therapies and urgent reperfusion. In multivariate analysis, CKD was a predictive factor of hospital (P=0.016), at 6 months (P=0.003), at 1 year (P=0.004) and at 2 years MACCE (P=0,015). The predictive factors of hospital MACCE in group 2 were: use of vasopressors (P=0.001) and primary angioplasty (P=0.043). In patients with CKD, only surgical coronary revascularization was MACCE predictive factor (P=0.03).
Baseline renal function is a powerful predictor of short- and long-term events after myocardial infarction. Our results confirm the need to include the renal function in the evaluation of the level of risk among patients admitted with acute myocardial infarction.

ABSTRACT: A 45 day old new-born with arrhythmia-induced cardiomyopathy complicated by thrombus formation is presented. Drug treatment produced immediate symptomatic relief and subsequent reversion to normal cardiac function. The thrombus disappeared a few days later.
