Hybrid surgical ablation for persistent or long standing persistent atrial fibrillation: A French single centre experience.

BACKGROUND: Hybrid ablation for the treatment of atrial fibrillation is a single combined procedure consisting in a minimally thoracoscopic surgical ablation followed by a catheter ablation. This promising technique is recommended in persistent atrial fibrillation according to the current guidelines but is not routinely performed in France, mainly due to the absence of reimbursement by the French National Health Insurance. AIMS: The aim of this prospective and single-centre study was to analyse, for the first time in France, the feasibility, efficacy and complication rates of hybrid ablation in patients with persistent atrial fibrillation. METHODS: Hybrid ablation was performed in 15 consecutive patients (13 men, mean age 61±6 years) with persistent (7 patients) or long standing persistent (8 patients) atrial fibrillation. RESULTS: Hybrid ablation was completed in 14/15 patients. Eleven patients returned in sinus rhythm during the procedure. Two patients (13%) had major per-procedural complications and 2 had minor complications. During an average follow-up of 25±6 months, 6 patients (40%) underwent a redo catheter ablation because of atrial tachycardia, mainly peri-mitral atrial flutter. At 1 year follow up, 14/15 patients were in sinus rhythm, including 11 free of antiarrhythmic drugs.

[Twenty years later A story of intra-thoracic textiloma]. / Vingt ans après Histoire d'un textilome intra-thoracique.

INTRODUCTION: Intrathoracic textiloma is a rare complication possibly leading to misdiagnosis. It could present as haemoptysis, lung abscess, pseudo-tumour or a chronic cough. CASE REPORT: A 65-year-old patient with a history of multiple cardiac problems and needing long-term anticoagulation, complained since 2007 of recurrent haemoptysis of increasing abundance, the etiological investigation of which was negative. A thoracic CT-scan revealed a lesion in the lingula in contact with the pericardial plates of an implanted automatic defibrillator dating from 1989. In 2016, after two failures of arterial embolization, a diagnostic and therapeutic surgical exploration was undertaken on this patient who was a high operative risk. A segmental resection revealed an intra-pulmonary textiloma on pathological examination. CONCLUSION: The diagnosis of intrathoracic textiloma remains rare and its late presentation is non specific. Radiological imaging with a CT-scan and/or MRI could lead to the diagnosis. Surgery remains the reference treatment for the diagnosis and cure of intrathoracic textiloma with pathological examination, essential for confirmation. A means of prevention has to be developed because swab count is not totally reliable.

[Mitral regurgitation associated with Wegener's granulomatosis]. / Insuffisance mitrale et maladie de Wegener.

BACKGROUND: Wegener's granulomatosis (WG) is a granulomatous disease that can affect many organ systems. The most frequently involved organs include the upper and lower respiratory tract as well as the kidney. Cardiac involvement is rare. METHODS: We report the case of a patient with grade 4 mitral insufficiency associated with severe WG. RESULTS: Surgical analysis of the mitral valve revealed perforation of the anterior leaflet without evidence of endocarditis. Pathological examination of the anterior mitral leaflet revealed myxoid degeneration nodules and bacteriological examination was negative. As the perforated lesion was very close to the free margin of the anterior leaflet, valve replacement appeared a reasonable surgical option in a poor surgical candidate. Six months after the operation, the patient is doing well. CONCLUSION: Wegener's granulomatosis is an autoimmune necrotizing vasculitis that can affect many organ systems. Cardiac involvement is rare. Heart in his globality can be affected by WG in many different ways. Cardiac valvular involvement in WG is rare. The aortic valve seems to be more frequently affected. Cardiologic investigations should have an important place at diagnosis and supervision.

[Late complications of a pseudo aneurysm of the left ventricle: thrombus infection and purulent pericarditis]. / Complications tardives d'un faux anévrisme du ventricule gauche: infection du thrombus et péricardite purulente.

Pseudoaneurysm is a rare complication of left ventricle myocardial infarction. Rupture with tamponade and sudden death is the usual outcome. Surgical intervention remains the treatment of choice. Long term survival cases without surgery are rare. Infection of the thrombus is also a possible event. We report the case of a patient with postinfarction left ventricular pseudoaneurysm complicated by infection of the thrombus and purulent pericarditis involving a peptostreptococcus. Infection must be considered a potential complication of left ventricular pseudoaneurysms.
