We report our experience with PCI in patients ≥80 years old over a four-year period at Waikato Hospital and the incidence of hospital readmission within one year due to cardiac aetiology. Methods: 164 consecutive PCI in 154 patients were performed from May 2006 to June 2010 in patients over 80 years. 101 patients with at least one year follow-up were included in theanalysis.All patientswhohadsuccessful or unsuccessfulprocedurewere included.All patientshadno known immediate non-cardiac life-threatening disease. Results: The mean age was 83± 3 yrs and 58% were male. The procedural success (defined as successful stent deployment) rate is 94%. The Kaplan Meier 2-year surResults:Of 106 patients (age 71± 16 yr), all had six-month follow-up data. Procedure types were 75% pacemaker and 25% Implantable Cardioverter-Defibrillator, of which 30% were bi-ventricular devices. Ten (10%) of the procedures involved device upgrade or lead revision. Major complications occurred in 5 (5%): one death at post-op day 2, two infections requiring additional procedure, one wounddehiscence requiring revision and one pre-erosion requiring pocket revision. Minor complications (defined as managed as an outpatient) occurred in eight (8%) patients: one haematoma lasting> 7 dayswith tenderness, one haematoma without tenderness, six had superficial wound infection requiring oral antibiotics. See Table for a summary of complications with simple device replacement or device upgrade.
