or an upgrade to cardiac resynchronization therapy (CRT).
or an upgrade to cardiac resynchronization therapy (CRT). The preferred site for introducing the additional electrodes is from the initial (ipsilateral) side of implantation. After the implantation of the device the vein that was used for implantation is likely to thrombose partially or completely later in time. Total venous occlusion is the main reason for failure in new electrode placement on the ipsilateral side and is observed in 5-26% of patients.

Some of them required upgrade to CRT.
Intheperiodfrom 01/01/2017 to 31/12/2017 in University Hospital “St. Ekaterina” in Sofia there was a total of 370 PM implantations. Some of them required upgrade to CRT. The latter were clinically examined for the presence of edema and feeling of heaviness of the upper limb. Ultrasonography was used to check for occlusion of the subclavian vein. Periprocedural phlebography was performed for assessing the venous access site.

One patient (0.58%) who required upgrade from VVI to DDD was diagnosed with an asymptomatic subclavian vein occlusion.
In the period from 01/01/2017 to 31/12/2017 there was a total of 370 PM implantations – 173 patients were on VVI mode and 140 on DDD mode. One patient (0.58%) who required upgrade from VVI to DDD was diagnosed with an asymptomatic subclavian vein occlusion. Cardiac resynchronization therapy (CRT-P and CRT-D) was applied in 57 patients. Upgrade from VVI/ DDD to CRT was required in 17 patients. Occlusive venous disease was diagnosed in 2 patients (21.79%), both of whom were asymptomatic.

Ultrasonography is a safe, fast and a very informative diagnostic method in determining venous thrombosis and is the preferred initial imaging modality in cases of suspected occlusive venous disease in patients who are to receive upgrade to their artificial pacemaker system.
Subclavian vein thrombosis in pacemaker implantation is a fairly rare complication that depends on individual patient anatomy, operating physician experience and the type of implanted device. In most cases it is asymptomatic. Ultrasonography is a safe, fast and a very informative diagnostic method in determining venous thrombosis and is the preferred initial imaging modality in cases of suspected occlusive venous disease in patients who are to receive upgrade to their artificial pacemaker system.

During the ipsilateral upgrade procedure to CRT the venous occlusion was confirmed with a continuous right subclavian vein occlusion present.
On CCDS, thrombosis of the right subclavian vein was observed with a normal left subclavian vein. During the ipsilateral upgrade procedure to CRT the venous occlusion was confirmed with a continuous right subclavian vein occlusion present. For the left ventricular electrode implantation an alternative venous access site through the left subclavian vein was used. The LV electrode was implanted in a lateral branch of the coronary venous system. The connector head of the LV electrode was placed in the initial (contralateral) side by tunneling over the sternum. A CRT device was implanted by using the RA and RV electrodes already in place. The patient was followed-up for 8 years being marked as a “responder”, with no dysfunction of the LV electrode.
