The prospective evaluation and follow-up of 39 consecutive subjects with VT/VF, 6 of whom, with cardiac arrest (CA), are reported. Patients were enrolled in a specific staged-care approach protocol, which included coronary arteriography (CAR) and ventriculography (VC), in order to exclude the need of cardiac surgery, including coronary artery bypass graft (CABG), with and without left ventricular aneurysmectomy (LVA). The protocol included inducibility of VT/VF, which was verified by programmed electrical stimulation (PES) in control conditions and after antiarrhythmic therapy (ADT), to assess persistent inducibility and mainly to verify the hemodynamic sequelae of VT. ⋯ Amiodarone + metoprolol seems to be the most effective ADT in these patients. Nevertheless, a high recurrence rate was observed in this patient population, even with an aggressive protocol, in the short follow-up period of 12 +/- 8 months, confirming recent data on the superiority of ICD to ADT, in patients with frequent recurrences or hemodynamically poorly-tolerated VT. In these patients, ICD therapy should definitively be preferred to ADT.

The accuracy of transesophageal echocardiography in the diagnosis and surgical management of acute aortic dissection was determined in 54 patients who underwent surgery for acute aortic dissection. Results of the investigations were compared to the surgical assessment. From April 1993 to November 1997, we operated 54 patients (44 male and 10 female) for acute aortic dissection. ⋯ It can be performed at the patient's bedside within just a few minutes of the suspected diagnosis, thereby lowering the mortality rate of the natural history. Again, it can also be used in the operating theatre as an "on-line examination" as well as for assessment of correct surgical repair. Other diagnostic procedures do not yield more information and can cause dangerous delays in intervention.

Comparative Study
[Guidelines and clinical practice: anticoagulant therapy and cardioversion in atrial fibrillation].
The cardioversion of atrial fibrillation is linked to a substantial risk of systemic embolization. In an effort to reduce it, the American College of Chest Physicians (ACCP) periodically publishes guidelines for the use of anticoagulation in the conversion of atrial fibrillation. ⋯ Anticoagulation for cardioversion of atrial fibrillation is underused, especially among elderly patients. In order not to let age itself be an obstacle to the correct treatment of patients with high embolic risk, our efforts must be improved in order to identify the correct therapeutic choice in each particular case. Initiatives aimed at identifying and removing any impediment to the application of guidelines may contribute to stimulating physicians in the process of evaluating the quality of hospital treatment.
