Is the right ventricular function affected by permanent pacemaker?

A rare case of late right ventricular perforation by a passive-fixation permanent pacemaker lead.

The present paper is an interesting and rare complication of implantation of a permanent pacemaker lead. The rarity of the case is based upon that ventricular perforation is usually present during implantation, whereas in our case, it was presented late--1 month after implantation. Furthermore, in our case, the pacemaker lead had migrated through the left hemidiaphragm into the peritoneal cavity.

Evaluation of Right Ventricular Function by Tissue Doppler Echocardiography in Asthmatic Children

BackgroundAsthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. We aimed to investigate Right Ventricular (RV) functions in asthmatic children by conventional and tissue Doppler echocardiography (TDE).Materials and Methods Pulmonary function tests, con...

Determination of the Effects of Digoxin on the Right Ventricular Function in Patients Undergoing Pneumonectomy

Introduction: Pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. We have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. Materials a...

Late deterioration of left ventricular function after right ventricular pacemaker implantation

OBJECTIVES Right ventricular (RV) pacing induces a left bundle branch block pattern on ECG and may promote heart failure. Patients with dual chamber pacemakers (DCPs) who present with progressive reduction in left ventricular ejection fraction (LVEF) secondary to RV pacing are candidates for cardiac resynchronization therapy (CRT). This study analyzes whether upgrading DCP to CRT with the addit...
