Conditions
Brief summary
Previous case studies have shown that intracardiac lead thrombus can cause pulmonary embolism (PE). However, the incidence of new or worsening pulmonary hypertension after cardiovascular implantable electronic devices (CIED) lead placement has not been well investigated. Pulmonary hypertension after CIED implantation will subsequently result in right heart failure and increase morbidity and mortality. This study is aimed to: I. Determine the incidence and factors associated with development of pulmonary hypertension and right ventricular dysfunction in patients with CIEDs. II. Determine the role of anticoagulation in the prevention of pulmonary hypertension in patients with CIEDs.
Interventions
Participants who have previously had a transvenous cardiac device implanted between 2009 to 2017 will be followed up with an annual echocardiogram up to 10 years post-cardiac device implantation, to investigate pulmonary artery pressure.

Inclusion criteria
1. All patients who underwent CIED implantation between 2009 and 2017 will be reviewed for inclusion 2. The eligible participants will only be identified from a single centre (Centre for Heart Rhythm Hospital/Royal Adelaide Hospital) 3. The control participants are the age-matched patients who have not had a CIED implanted but who have had an annual echocardiogram follow-up
Exclusion criteria
- patients without any follow-up of at least two echocardiograms (first within 6 months and the second greater than 1 year following implant)
