Case Reports[The diagnosis by a Doppler color echocardiographic method of an aortocaval fistula following the rupture of an aortic aneurysm into the inferior vena cava].
We describe a clinical case presenting 2 rare features. The first was a spontaneous aortocaval fistula which had developed from rupture of an atherosclerotic aortic aneurysm into the inferior vena cava. ⋯ In fact, using an echo-color Doppler flow imaging (HP 77020A ultrasound system) with a 2.5 MHz echocardiographic probe abdominal examination showed an aneurysm of the descending aorta that communicated to a dilated inferior vena cava. Furthermore, flow study with color Doppler showed a continuous turbulent, mixed (arterial and venous) blood flow into the inferior vena cava.

Case ReportsOpposite effects of propafenone and flecainide in a patient with reciprocating supraventricular tachycardia.
A 46 year-old woman with Wolff-Parkinson-White syndrome (postero-septal accessory pathway), symptomatic for recurrent episodes of nonsustained paroxismal supraventricular tachycardia (PSVT), was empirically treated with propafenone (600 mg/day). After a week of therapy the patient returned to the hospital after an episode of syncope. She referred a significant increase in duration and frequency of "palpitations". ⋯ The patient has been asymptomatic on chronic oral therapy with flecainide during a follow-up period of 8 months. This case shows that 2 1c class antiarrhythmic drugs may have opposite effects (proarrhythmic and antiarrhythmic). Failure, or even the proarrhythmic effect of one drug, does not necessarily exclude the efficacy of another drug of the same subclass in preventing recurrence of PSVT.

[Correlation between the sites of mitral annular calcification and conduction disturbances: echocardiographic evaluation].
A clinical, electrocardiographic and echocardiographic (M-Mode, 2D) study was performed to explain the causal relationship between mitral annular calcification and cardiac conduction disturbances. Forty-seven patients, 28 women and 19 men (mean age 69) with mitral annular calcification were studied. In 18 patients A-V and/or intraventricular conduction disturbances were present. In this study we have found: a greater incidence of posterior than anterior mitral annular calcification; the anterior mitral annular calcification is often associated with aortic valve calcification and ultimately the common association between anterior mitral annular calcification and conduction disturbances.
