First report of phrenic nerve injury during pulmonary vein isolation using the Ablation Frontiers pulmonary vein ablation catheter.
Summary of "First report of phrenic nerve injury during pulmonary vein isolation using the Ablation Frontiers pulmonary vein ablation catheter."
In an attempt to improve procedural outcomes and reduce time and complications, there has been particular interest in alternative technologies specifically designed for atrial fibrillation (AF) ablation. One novel technique is isolation of the pulmonary veins using an over-the-wire multielectrode catheter delivering duty-cycled bipolar and unipolar radiofrequency energy. Phrenic nerve injury is a rare but significant complication of AF ablation. This is the first report of phrenic nerve injury following catheter ablation for AF using the Pulmonary Vein Ablation Catheter (Medtronic, Minneapolis, MN, USA).

Medical and Biotech [MESH] Definitions
The motor nerve of the diaphragm. The phrenic nerve fibers originate in the cervical spinal column (mostly C4) and travel through the cervical plexus to the diaphragm.
Complete or severe weakness of the muscles of respiration. This condition may be associated with MOTOR NEURON DISEASES; PERIPHERAL NERVE DISEASES; NEUROMUSCULAR JUNCTION DISEASES; SPINAL CORD DISEASES; injury to the PHRENIC NERVE; and other disorders.
Abducens Nerve Injury
Traumatic injury to the abducens, or sixth, cranial nerve. Injury to this nerve results in lateral rectus muscle weakness or paralysis. The nerve may be damaged by closed or penetrating CRANIOCEREBRAL TRAUMA or by facial trauma involving the orbit.
Central retinal vein and its tributaries. It runs a short course within the optic nerve and then leaves and empties into the superior ophthalmic vein or cavernous sinus.
An anomalous pulmonary venous return in which the right PULMONARY VEIN is not connected to the LEFT ATRIUM but to the INFERIOR VENA CAVA. Scimitar syndrome is named for the crescent- or Turkish sword-like shadow in the chest radiography and is often associated with hypoplasia of the right lung and right pulmonary artery, and dextroposition of the heart.
ABSTRACT: BACKGROUND: Among a variety of more common differential diagnoses, the aetiology of acute respiratory failure includes Lyme neuroborreliosis. CASE PRESENTATION: We report an 87-years old hun...
Neurologic complications from radiotherapy can be immediate or can occur many years after treatment. A known complication of radiotherapy to the supraclavicular and axillary lymph nodes is brachial pl...
This report describes 2 symptomatic patients with phrenic nerve palsy due to Parsonage-Turner syndrome who were managed by diaphragmatic plication. The characteristics of the underlying syndrome are d...
For surgeries aimed at the dissection of full-length phrenic nerve, a full appreciation of its trajectory, blood supply and correlation with adjacent anatomical structures is necessary, especially for...
Extracellular matrix (ECM) proteins and their proteolytic enzymes, matrix metalloproteinases (MMPs), implicate in neuromuscular junctions (NMJs) function during development. However, their pathophysio...
The purpose of the study is to investigate the impact of unilateral or bilateral diaphragm plication in a prospective randomised controlled way on symptoms, pulmonary function including ga...
In this study, we sought to determine whether a stimulation of the phrenic nerve affects heart function. Heart function is assessed by acoustic cardiography.
the purpose of this study is to compare the oesophageal depression induiced by bilateral phrenic nerve stimulation during swallowing in patients with neurological laryngeal aspiration
The PING-EP study is designed to evaluate electrode properties on phrenic nerve stimulation (PNS) in coronary sinus using a commercially available diagnostic electrophysiology catheter.
The purpose of this feasibility study is to determine the effect of phrenic nerve stimulation on periodic breathing (a pattern of breathing characterized by hyperpneas followed by hypopnea...
