[A case of a iatrogenic defect of the tricuspid valve caused by endocardial electrodes]. / Nabliudenie iatrogennogo poroka trekhstvorchatogo klapana, obuslovlennogo éndokardial'nymi élektrodami.

One case of a rare complication of the permanent heart electrostimulation is observed among many patients treated with such method for many years. A 77-year-old man having a permanent electrostimulation during 13 years because of a complete atrioventricular heart blockade, developed a defect of the tricuspid valve resulting from two endocardial electrodes. Narrowing of the right atrioventricular aperture and a severe dilatation of the right atrium worsened the circulation deficiency. More frequent use of various methods of the nonfunctioning endocardial electrode elimination is recommended. Transvenous destruction of the fibrous capsule at the end of endocardial electrodes is an efficient method developed by the authors for their elimination.
