390: Transvenous Pacing Through Coronary Sinus in a Patient With Ventricular Dyssynchrony

Ventricular Pacing via the Coronary Sinus in a Patient with a Mechanical Tricuspid Valve Prosthesis

Implantation of a transvenous endocardial pacing lead in the right ventricle is contraindicated after mechanical tricuspid valve replacement; therefore a surgical approach to the epicardium is usually required. This case report describes ventricular pacing via a branch of the coronary sinus in a patient with mechanical mitral, aortic and tricuspid valve replacements. In conclusion, this approac...

Transvenous dual‐chamber pacemaker after paediatric heart transplantation using left ventricle pacing through the coronary sinus

A 12-year-old child with end-stage heart failure due to restrictive cardiomyopathy was submitted to orthotopic heart transplantation. Primary graft dysfunction required venous arterial extra-corporeal membrane oxygenation. Heart function normalized, but complete atrioventricular block remained after 3 weeks. A dual-chamber pacing with transvenous left ventricle pacing through the coronary sinus...

Transvenous right ventricular pacing in a patient with tricuspid mechanical prosthesis

We report a patient in whom permanent endocardial pacing was accomplished by passage of the electrode through a mechanical tricuspid valve. Echocardiography study showed a minimal tricuspid regurgitation.

Right Ventricular Pacing and Mechanical Dyssynchrony

Coronary sinus dissection during left ventricular pacing electrode implantation.

Coronary sinus (CS) dissection during biventricular pacing electrode implantation is a complication that rarely develops. A 71-year-old female with recurrent ventricular tachycardia, heart decompensation, and poor left ventricular function because of dilated cardiomyopathy was admitted for the implantation of a cardioverter-defibrillator for biventricular pacing. During the operation, we experi...
