BACKGROUND Two-dimensional (2D) echocardiographic approaches based on geometric assumptions face the greatest limitations and inaccuracies in patients with left ventricular (LV) aneurysms. Three-dimensional (3D) echocardiographic techniques can potentially overcome these limitations; to date, however, although tested in experimental models of aneurysms,(More)
INTRODUCTION Atrioesophageal fistula is an uncommon but often lethal complication of atrial fibrillation (AF) ablation. The purpose of our study was to prospectively investigate the incidence of esophageal ulcerations (ESUL) as well as the impact of energy settings, radiofrequency lesion sets, and direct visualization of the esophagus on esophageal wall(More)
Several independent studies suggest that resynchronization therapy--achieved by left- or biventricular pacing--improves hemodynamics in heart failure patients with interventricular conduction disturbances. Delivery of this new therapy in an effective and minimally invasive manner presents technical challenges, as transvenous access to the left ventricle is(More)
This study sought to test whether anomalous cardiac and aortic structures can be differentiated from native tissue and artifacts by physical properties of tissue motion using transesophageal tissue Doppler echocardiography (TDE). TDE was employed in 85 consecutive patients after anomalous structures had been detected by conventional transesophageal(More)
Following pacemaker implantation, a 71-year-old female developed infection of the generator pocket. Five years after relocation posterior to the rectus muscle she suffered from cystitis. Cystoscopy revealed the pacemaker generator to be lying within the urinary bladder. Healing was achieved by removing the pacemaker and reutilizing it, after sterilization,(More)
We report the case of an 85-year-old woman with distal LV hypertrophy resulting in an intraventricular pressure gradient and incomplete systolic emptying who benefited from permanent DDD pacing. Our experience based on this case suggests that permanent dual chamber pacing might be a safe and effective therapy also in symptomatic patients with the rare form(More)
BACKGROUND Phrenic nerve stimulation (PNS) complicates the positioning of the left ventricle lead. We present a step-by-step approach to correct PNS during implantation, as established in our daily routine. METHODS The incidence of PNS, its successful correction, and long-term results (median 27 months) were analyzed retrospectively in 266 lead positions.(More)
BACKGROUND Persistent inappropriate sinus tachycardia may evolve as a complication after radiofrequency (RF) fast pathway ablation of atrioventricular nodal reentrant tachycardia (AVNRT). Parasympathetic denervation may serve as one of the possible mechanisms. We performed a study to show the prevalence of this phenomenon in RF ablation of the slow pathway.(More)
During a period of 22 months there were 84 cases of congenital cardiac malformations diagnosed during the first year of life. This figure corresponds to about 80% of all existing cardiac malformations present in the population covered. Noninvasive measures including echocardiography were sufficient for diagnostic and therapeutic decisions in 75% of the(More)
