Key result
CS guiding catheter enables successful ICD lead implantation into the MCV following tricuspid valve surgery.
Why the study?
Implanting transvenous leads across a surgically treated tricuspid valve can worsen valve function and should be avoided when possible.
A coronary sinus guiding catheter can facilitate ICD lead implantation into the middle cardiac vein, avoiding transvenous lead placement across a surgically treated tricuspid valve.
Answers are grounded in this paper and cite their sources.
May enable transvenous ICD placement without crossing the tricuspid valve; leaves open the need for confirmatory data in larger cohorts.
Implantation of transvenous leads across a surgically treated tricuspid valve can worsen valve function and should be avoided when possible. We report a case in which a coronary sinus (CS) guiding catheter enabled the successful implantation of an implantable cardioverter defibrillator (ICD) lead into the middle cardiac vein (MCV) in a patient with prior tricuspid valve surgery.
