Abstract Background Phrenic nerve stimulation is a well-recognized complication related to cardiac implantable electronic devices, in particular with left ventricular coronary sinus pacing leads for resynchronization therapy. Case presentation We report an unusual case of symptomatic phrenic due inadvertent placement right defibrillation lead posterior branch patient heart failure reduced eject...

Hiccups have more than 100 etiologies. The most common etiology has gastrointestinal origins, related mainly to gastric distention and gastroesophageal reflux disease. Intractable hiccups are rare but may present as a severe symptom of various diseases. Hiccups are mostly treated with non-invasive or pharmacological therapies. If these therapies fail, invasive methods should be used. Here, we p...

BACKGROUND The etiology of diaphragm paralysis is often elusive unless an iatrogenic or traumatic injury to the phrenic nerve can be clearly implicated. Until recently, there has been little interest in the pathophysiology of diaphragm paralysis since few treatment options existed. METHODS We present three cases of symptomatic diaphragm paralysis in which a clear clinico-pathologic diagnosis ...

Introduction Phrenic nerve injury is a recognized complication of catheter ablation procedures for atrial and ventricular arrhythmias. The posterolateral right atrium (RA) is a common site of origin for atrial tachycardias (AT), but ablation in this region can be hazardous because of the proximity of the right phrenic nerve (RPN). Proximity to the nerve may be identified by capture during pacin...

We studied respiratory mechanics and phrenic nerve and diaphragm function in 12 patients on the day before and eight to 13 days after coronary artery bypass grafting. The average vital capacity, functional residual capacity, and total lung capacity decreased by 20.5%, 9.5%, and 14.7% respectively after operation. Eleven patients showed less negative maximum inspiratory mouth pressures at any gi...

Diaphragmatic dysfunction is a common postoperative complication of cardiac surgery in children, with important effects on respiratory morbidity. Its early diagnosis, followed by prompt surgical intervention, has been shown to reduce morbidity. However, the commonest method of diagnosis, based on hemi-diaphragmatic elevation on the chest radiograph, may be less accurate than direct techniques f...

Diaphragmatic pacing is a valuable tool that can significantly benefit certain patients with respiratory insufficiency provided they have an intact phrenic nerve and a functional diaphragm. Careful patient selection is critical to successful long-term results. The main populations that derive benefit from pacing include those with congenital or acquired central hypoventilation syndrome and more...

Catheter ablation within the right atrium can be limited by proximity to phrenic nerve and potential for hemi diaphragmatic paralysis. High output pacing is frequently employed map position relative endocardium, particularly in relation superior vena cava pulmonary vein. The use of intracardiac echocardiography (ICE) correlation with lower rigorously course along has not been previously describ...
