ABSTRACT
Cor triatrium sinister is a rare congenital disease [0,1% of cases of congenital heart disease]. Cor triatrium is recognized by the finding of an abnormal fibromuscular membrane that subdivise the left atrium into posterosuperior and anteroinferor chambers. This anomaly creates an obstacle to the venous pulmonary flow. Depending on the severity of obstruction, cor triatrium may be symptomatic in childhood but it can be symtom free even in adulthood. Diagnosis of this abnormality has been easy supported by transthoracic and transoesophageal echocardiography. Treatment is easy to perform and consists in surgical definitive correction in symptomatic patients. We report a case of a 31-year-old man in whom a non obstructive cor triatrium was discovered while evaluation for an atrial fibrillation secondary to a hyperthyroidism. According to this rare case we try to evaluate the severity and the outcome of this disease relating the literature data

We present three cases of short-coupled variant of torsade de pointes with review of the literature. These women presented with syncope or presyncope due to torsade de pointes initiated by a short-coupled premature ventricular beat and without evidence of prolonged QT. There were no electrolyte disturbances in all cases, no apparent structural heart disease in two cases and a mild interventricular septum hypertrophy in the other case. One patient took spiramycin and metro nidazole and another was taking pheniramin and lincomycin without any evidence of cause to effect relationship. One patient responded to verapamil but died suddendly after 44 months of follow-up. The two others. Received implantable cardioverter-defibrillators and verapamil per os. They still alive 46 and 54 months later. Short-coupled variant of torsade de pointes have a high incidence of sudden death, so it is very important for physicians to identify and treat it promptly, long-term verapamil treatement is effective but still insufficient and patients should be considered for implantable cardioverter-defibrillator therapy
