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.

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.

[Esophageal motility in systemic sclerosis and primary Raynaud' phenomenon by esophageal scintigraphy with semisolid meal].

Background: Esophageal transit scintigraphy seems to be a valid methodology to assess impaired esophageal motility, also in the early stages of disease.

Aim: To discriminate patients with primary Raynaud's phenomenon (RPh and patients with systemic sclerosis (SSc) from healthy subjects, by esophageal scintigraphy with a semisolid meal.

Methods: Thirty-two patients with primary RPh, 18 patients with SSc and 13 healthy subjects have been studied.
