Abstract
Cardiac resynchronization therapy (CRT) is an important treatment for
patients with heart failure.1,2 In clinical practice,
it is difficult to advance a left ventricular (LV) lead through narrow
or tortuous vessels in some cases. In this report, we present a case of
successful advancement of an LV lead into tortuous vessels. This was
achieved by deep engagement of the coronary sinus with a cannulation
catheter by applying the anchor technique using the Medtronic Attain
Stability Quad lead. This useful technique for LV lead delivery has not
been previously reported in the literature.
