Transthoracic second harmonic two- and three-dimensional echocardiography for detection of patent foramen ovale.

Aims: Transoesophageal echocardiography (TEE) with contrast administration is still considered as the reference method for the detection of patent foramen ovale (PFO) with interatrial shunt, but it is a semi-invasive exam. The aim of the present study is to evaluate a role of two- and three-dimensional transthoracic echocardiography (TTE and R3DTE) as a diagnostic alternative to transcranial Doppler ultrasound (TCD) and TEE for detection of atrial right-to-left shunt.

Methods And Results: Seventy-five patients with history of cerebrovascular events were subjected to four diagnostic examinations: TCD, TTE, R3DTE, and TEE, with bubble contrast.

Digitalis must be banished from the table: a rare case of acute accidental Digitalis intoxication of a whole family.

Advanced Digitalis intoxication is a rare event, mainly associated with overdose in patients with Digitalis therapy. We report an unusual case of acute 'familiar' digitalis poisoning in three patients who had eaten potato dumplings flavoured with leaves of Borago officinalis L. unconsciously mixed with leaves of Digitalis purpurea L.

Biventricular pacemaker lead thrombosis: a rare case treated with surgical thrombectomy.

Right cardiac thrombosis is an infrequent complication after pacemaker implant. We report a patient who received a biventricular implantable cardioverter defibrillator, with a large mobile thrombus, adherent to the left ventricular lead. This catheter was partially dislocated, with a large, mobile loop through the right atrium and right ventricle; so the lead thrombus could alternately obstruct the pulmonary valve and the tricuspid valve.

[Effects of pretreatment with amiodarone infusion in patients with persistent atrial fibrillation submitted to external electrical cardioversion: a single center experience].

Background: Several studies demonstrated the efficacy of amiodarone pretreatment in achieving bet-ter outcomes after electrical cardioversion of atrial fibrillation. In the majority of cases, oral amiodarone for at least 1 month was administered, with the result of lengthening of pre-cardioversion time. Only one study in the literature reported high-dose amiodarone infusion, showing an increase in the incidence of slow arrhythmias.

Interventricular cardiac resynchronization with right ventricular apical pacing in a patient with Ebstein's defect.

We present the case of a patient with Ebstein's defect surgically corrected, and a complete right bundle branch block (RBBB) documented on echocardiogram. After an episode of near syncope due to a high-grade atrioventricular (AV) block, the patient was assisted with a bicameral DDDR pacemaker implanted with traditional right ventricular apical pacing. After the DDDR, and after stimulation with an AV delay of 180 ms, a narrow QRS complex was observed.

Left ventricular pseudoaneurysm: an atypical case associated with a small ventricular septal defect.

We present an atypical case of postinfarction left ventricular pseudoaneurysm involving the posterobasal septal wall, with protrusion into the right ventricle, associated with a small septal defect and left-to-right shunt. In this case, a conservative approach was adopted rather than surgical management, and the patient had a good clinical outcome. Subsequent evaluation with two-dimensional colour Doppler, three-dimensional echocardiography and 16-slice computed tomography is reported.

[Severe bradycardia in an asymptomatic young subject: is there an indication to permanent cardiac pacing?].

Bradycardic effects of severe weight loss are well known like those observed in anorexia nervosa resulting from an increase in vagal tone associated with a low calorie-protein diet. We here report the case of a 19-year-old patient with asymptomatic severe bradycardia, which developed after voluntary weight loss of more than 30 kg during a few months. In absence of symptoms, ventricular arrhythmia or structural heart disease, and owing to normal ventricular function, no permanent pacemaker implantation was undertaken.

[Late pacemaker pocket erosion: epidemiologic analysis in a region of North-Western Italy (Piedmont and Valle d'Aosta)].

Background: Pacemaker pocket erosion is still a relevant clinical problem as it may be the cause of septicemias and/or endocarditis with consequent poor prognosis. The true incidence of this complication is rather variable in the various series of cases reported in the literature ranging between 0.9 and 5% when early infective complications are included.
