ABSTRACT

A 60-year-old male patient was urgently admitted to the hospital with chest pain, anemia and shock. The echocardiographic examination revealed myocardial tamponade and, unexpectedly, a mobile mass in the right atrium, prolapsing in the right ventricle which was indicative of myxoma. The patient underwent pericardiocentesis which showed the presence of blood. Cardiac surgery was then performed to remove the tumor which was found to originate in the right atrial appendage. There were some adhesions between the atrial appendage and the anterior wall of the right ventricle. The tamponade was due to a trauma of some small pericardial arteries in the adhesion area. The presence of tamponade and right atrial myxoma, is the peculiar finding of the reported case.

ABSTRACT

The echocardiographic detection of a right thromboembolus, although rare, should be considered as a cardiological emergency that could lead to death for massive pulmonary embolism. The case of a 70 year-old man admitted to our Institution with the suspicion of pulmonary embolism is described. The echocardiogram performed showed a large mobile thrombus in the right atrium prolapsing through the tricuspid valve during diastole. After thrombolytic therapy with r-TPA, the patient faced a progressive hemodynamic deterioration and died of electromechanical dissociation.

ABSTRACT

Torsade de pointes is a form of polymorphous ventricular tachycardia in which the polarity of the QRS complex exhibits phasic alterations in both axis. Traditionally, torsade de pointes has been described in association with a congenital or acquired (including drug and metabolic) causes of QT prolongation. Clinical outcomes range from asymptomatic, self-terminating arrhythmias to ventricular fibrillation resulting in cardiac arrest. For the treatment of torsade de pointes, the conventional antiarrhythmic drugs cannot be relied on, cardiac pacing should be instituted as soon as possible; however, as this technique may not always be immediately available, isoproterenol infusion may be the first-choice treatment. Potassium and magnesium repletion appear to be essential in abolishing drug-induced torsade de pointes. This report describes a case of thioridazine-induced torsade de pointes treated efficaciously with magnesium sulphate and overdrive right ventricular pacing.
