Late presentation of constrictive pericarditis after limited epicardial ablation for inappropriate sinus tachycardia
نویسندگان
چکیده
The number of radiofrequency catheter ablation (RFA) procedures performed in the epicardial space is increasing. Major acute complications (primarily pericardial bleeding) and delayed complications have been reported in 5% and 2% of cases, respectively. To the best of our knowledge, a single case of constrictive pericarditis after multiple epicardial ablations for ventricular tachycardia has been reported. We describe a late presentation of constrictive pericarditis that occurred after a single percutaneous epicardial procedure with limited ablation for inappropriate sinus tachycardia.

Constrictive pericarditis presenting as a late complication of epicardial ventricular tachycardia ablation.
Radiofrequency epicardial ablation of ventricular tachycardia (VT) is a safe, effective modality for treatment of VT.1 Epicardial VT circuits were originally described in Chagas disease, but the importance of nonendocardial substrates for VT increasingly are recognized in other cardiomyopathies.2 In arrhythmogenic right ventricular cardiomyopathy (ARVC), failure of endocardial VT ablation often...
متن کاملA novel method for sinus node modification and phrenic nerve protection in resistant cases.
This is a case report of inappropriate sinus tachycardia in a patient who had a previous unsuccessful endocardial ablation, which had been limited due to concerns of phrenic nerve injury. The patient required a repeat ablation that utilized a novel combined epicardial and endocardial approach for sinus node modification and simultaneous protection of the phrenic nerve via an epicardial balloon.
متن کاملAnti-inflammatory properties of amniotic membrane patch following pericardiectomy for constrictive pericarditis
BACKGROUND Since constrictive pericarditis is most often idiopathic and the pathophysiology remains largely unknown, both the diagnosis and the treatment can be challenging. However, by definition, inflammatory processes are central to this disease process. Amniotic membrane patches have been shown to possess anti-inflammatory properties and are believed to be immune privileged. Due to these pr...
متن کاملLong-term follow-up of minimally invasive video-assisted thoracoscopic surgery with epicardial radiofrequency ablation for complex cases of inappropriate sinus tachycardia
Introduction Inappropriate sinus tachycardia (IST) is a rare disorder defined as a nonparoxysmal rhythm originating from the sinus node associated with palpitations with a resting heart rate 4100 beats/min and a 24-hour mean heart rate 490 beats/min, with all other potential causes of sinus tachycardia excluded. Patients with IST may experience debilitating palpitations, lightheadedness, chest ...
متن کاملPercutaneous pericardial instrumentation for endo-epicardial mapping of previously failed ablations.
BACKGROUND The epicardial location of an arrhythmia could be responsible for unsuccessful endocardial catheter ablation. METHODS AND RESULTS In 48 patients referred after prior unsuccessful endocardial ablation, we considered percutaneous, subxiphoid instrumentation of the pericardial space for mapping and ablation. Thirty patients had ventricular tachycardia (VT), 6 patients had a right- and...
