ABSTRACT

A 55-year-old man with signs of infectious endocarditis was admitted to the clinic in order to remove the CRT-D system. Due to difficult anatomical conditions and technical limitations, the decision was made to perform two-stage procedure and removal of the left ventricular lead by access from the femoral vein.

STRESZCZENIE

Mężczyzna, 55-letni, z objawami infekcyjnego zapalenia wsierdzia został przyjęty do kliniki w celu usunięcia układu CRT-D. Z uwagi na trudne warunki anatomiczne i ograniczenia techniczne, zdecydowaniu o przeprowadzeniu zabiegu dwuetapowo i usunięciu lewej elektrody komorowej przez dostęp z żyły udowej.

Case report

A 55-year-old man was referred to our clinic for extraction of a Cardiac Resynchronization Therapy Defibrillator (CRT-D) because of lead-dependent infective endocarditis. The CRT-D was implanted 7 years earlier in primary prevention due to chronic heart failure with decreased left ventricular ejection fraction (LFEV = 30%). His medical history was positive for myocardial infarction, left bundle branch block, paroxysmal atrial flutter and electrical storm treated with radiofrequency ablation.

The patient was qualified for transvenous lead extraction via left subclavian vein. The procedure was performed in general anaesthesia with on-site cardiac surgery backup. Originally simple traction revealed heavy adhesions in the subclavian region. The locking stylet (Liberator® Beacon® Tip Locking Stylet, Cook Medical Inc.) along with 10F and 11.5F mechanical telescopic sheaths (Byrd Dilator® sheaths, Cook Medical Inc.) were used (Fig. 1). It allowed to remove completely only the right ventricular lead and the left ventricular (LV) lead was disrupted with its tip wedged in the lateral branch of coronary sinus. The atrial lead was extracted with hand-powered sheath (Evolution® RL Controlled-Rotation Dilator Sheath Set) (Fig. 2). It was decided to stage the procedure and to continue it with femoral access.

In the second stage, self-locking device station Needle’s Eye Snare® (Cook Medical Inc.) was introduced to the inferior vena cava through the right femoral vein. The LV lead was grabbed at the level of right atrium and the outer sheath was advanced over it to the coronary sinus and the tip of the lead have been released (Fig. 3, 4). The procedure was uncomplicated and two days later the patient was transferred to another hospital for further treatment.

Discussion

Infective endocarditis is an uncommon infectious disease with an annual incidence ranging from 3 to 7 per 100 000 person-years in the most contemporary population surveys. Although relatively rare, it continues to be characterized by increased morbidity and mortality and is now the third or fourth most common life-threatening infection syndrome [1]. A population-based study found an incidence of cardiac device-related endocarditis infection of 1.9 per 1000 device-years [2]. Currently, two-thirds of all extractions are due to cardiovascular device-related infection [3].

Considering the inherent risk of an open surgical procedure, transvenous lead extraction has become the preferred method in centres committed to a procedural volume. However, unlike our case, typically it is considered that removal of the CS lead is easier than cardioverter-defibrillator leads and usually it requires only simple manual traction [2].

There are described case reports about the femoral vein approach, for the extraction of the pacemaker lead by using a snare [4, 5]. In the present case, as is rarely in literature, the femoral access was used to remove the coronary sinus lead. However, Bongiorni et al. described the use of a similar technique for dozen patients: in case of free-floating leads with free tips (leads migrated into the venous system) an analogous to our tool was used to grasp the lead. Once the lead was grabbed, it was pulled back into the workstation and removed; in case of adherences, dilatation was performer using the workstation [6].
