Atrial tachycardias (AT) often occur after ablation of long-lasting persistent AF (CAF) and are difficult to treat conservatively. This study evaluated mechanisms success rates conventional mapping catheter recurrent ATs occurring late stepwise CAF. A total 320 patients underwent de novo CAF using a approach in 2006 2007 at our institution. comprised who presented with their first redo procedure initial ablation. All procedures were guided by techniques exclusively. Sixty-one (63+/-10 years,...
Background— Termination of persistent atrial fibrillation (AF) can be achieved through ablation, with the majority patients terminating to an tachycardia (AT) and fewer directly sinus rhythm (SR). We aimed identify potential predictors for existence a substrate AT on termination SR. Methods Results— assessed 95 AF (age, 60±10 years) who underwent catheter ablation end point termination. Forty terminated SR (SRterm) 55 ATs (ATterm). Compared ATterm group, SRterm group were younger (56±10...
Different cardiac arrhythmias have been suggested to be associated with Danon disease, e.g. Wolff-Parkinson-White syndrome. However, a systematic electrophysiological investigation of patients disease is lacking thus far.Seven (4 males, 35.8 ± 10.8 years; 3 females, 51.3 19.9 years) from different families were studied. In all patients, the presence was confirmed by western blot biopsy material or genetic testing. The characterized 12-lead electrocardiogram (ECG), Holter ECG,...
Open irrigated radiofrequency (RF) ablation catheters with a porous tip (56 holes, TC-SF) permit delivering RF energy in temperature-controlled mode without temperature rise. This prospective observational study investigated the association of different catheter parameters on occurrence audible steam pops during left atrial (LA) ablation.A total 226 patients underwent TC-SF for fibrillation. power delivery, impedance and were continually recorded throughout ablation. Pulmonary vein isolation...
The role of subsequent atrial tachycardias (AT) in the context persistent fibrillation (AF) remains undetermined. This study evaluated prognostic ATs for arrhythmia recurrences after catheter ablation AF.A total 110 patients with AF (63±9 years; 22 women; 61 long-lasting AF) underwent pulmonary vein isolation followed by electrogram-guided ablation. After terminated to AT, were separated randomization protocol receive either direct cardioversion (group A) or further sinus rhythm B). a mean...
The formation of monocyte–platelet aggregates and neutrophil–platelet (MPA NPA, respectively) is influenced by inflammation, but also might contribute to an exacerbation inflammatory responses in atherosclerotic plaque. purpose this study was analyze MPA NPA proportions regard different stages peripheral arterial disease (PAD). Forty-five patients with intermittent claudication (IC) (3 groups: Rutherford (R)-1, R-2, R-3; each n = 15), 20 critical limb ischemia (CLI) (Rutherford 5 (40%) 6...
Persistent atrial fibrillation (persAF) can occur either as a sustained arrhythmia that has progressed from initially paroxysmal AF or primary persAF without history of any spontaneously terminated episode. There is paucity data differentiating between the 2 different entities. Thus, we prospectively evaluated baseline characteristics, electrophysiological features, and ablation outcome in these patient cohorts.A total number 154 consecutive patients (63 ± 10 years, f = 42, longstanding 60)...
Pulmonary vein isolation (PVI) is still associated with a substantial number of arrhythmia recurrences in paroxysmal atrial fibrillation (AF). This prospective, randomized study aimed to compare 2 different procedural strategies.A total 152 patients undergoing de novo ablation for AF were treatment arms. The procedure group A consisted PVI exclusively. In this group, all isolated PVs challenged adenosine reveal and ablate dormant conduction. B, was performed the patient either spontaneous or...
Abstract We report a case of ergotamine tartrate induced severe vasospasm in the renal arteries and lower extremities. Classic features seen on peripheral angiography make diagnosis. Anticoagulation, thrombolysis, vasodilation, steroids, prostaglandin inhibitors all have been successfully used to treat symptomatic ergot arterial vasospasm. Although balloon angioplasty has described reports, is self limited medically treatable condition that does not require mechanical intervention, unless...
Implantable cardioverter defibrillators (ICD) may have the capacity to provoke or worsen ventricular tachyarrhythmias (VT). It has been reported that ICD shocks by itself can increase mortality. This study aimed determine role of back-up pacing-induced VT (PIT) in overall shock burden avoiding pause-related pacing.A population 550 single-chamber patients was studied. Of them, 17 (3%, 69 ± 16 years, 14 male) had documented episodes PIT. A total 431 were including 89 (21%) due In 3 patients,...
We investigate different techniques for fitting Bézier curves to surfaces in context of high-order curvilinear mesh generation. Starting from distance-based least-squares we develop an incremental algorithm, which incorporates approximations stretch and bending energy. In the process, algorithm reduces energy weight favor accuracy, leading optimized set sampling points. This energy-minimizing strategy is applied analytically defined as well triangulated surfaces. The results confirm that...
Two hundred renal transplantations were performed on 187 patients between July, 1972 and June, 1978. On a follow-up of 6--78 months the survival rate after allogenic transplantation was 80% at one year 64% five years. Satisfactory function present in 62% 31% six Gastrointestinal complications common caused about 40% all deaths. Severe infections second most cause death. Local required explantation 4%, death 0.5% cases. Change treatment regimen, using less massive immunosuppressive measures...
Die idiopathische Pulmonalisektasie ist eine besonders im Kindesalter häufiger anzutreffende Anomalie, die keine hämodynamischen Auswirkungen besitzt. Auch bei bestimmten Herzfehlern vorkommende Dilatation der Lungenarterie hat nur symptomatische Bedeutung. 4 Beispiele wurden gebracht. Diesen Formen das echte Aneurysma Arteria pulmonalis gegenüberzustellen, welches wir neuerdings 3 Kindern mit isolierter oder kombinierter Pulmonalstenose beobachten konnten. Zwei frühere Fälle hatten...
Report of PTA renal arteries in 288 patients. Primary results show good to optimal dilatation the (60.6% 78.6%). One third all cases achieved blood pressures. In about 40% antihypertensive drugs had be administered, 30% pressure remained unchanged although was effective. is best method treating hypertension, also because low rate complications.
