Long Term Follow-up Hybrid Revascularization

Long Term Follow-up of Robotic Hybrid Surgical Revascularization With CT Angiography

OBJECTIVES:

The objectives of the year study are two-fold:

1. To determine the 5-7 year patency rate (rate of open bypass grafts) of the LITA graft and stent of patients who have already had robotically-assisted Hybrid CABG surgery using CTA and MPS-MIBI.
2. To determine patient quality of life at 5-7 years after robotically-assisted Hybrid CABG surgery

New techniques such as robotically-assisted Hybrid CABG surgery need proper evaluation to ensure potential benefits gained are not harmful to that which we know to be of significant benefit to the patients, that being the left internal thoracic artery (LITA) graft (one of the main coronary arteries supplying your heart with blood). We are therefore proposing a 5-7 year CT-Angiography (CTA) and Myocardial Perfusion Scintigraphy (MPS-MIBI) to assess the patency rate of the LITA graft and the stented graft in patients that have already undergone robotically assisted Hybrid CABG.

Inclusion Criteria:

- Patients that have previously had Hybrid robotic coronary artery revascularization performed approximately 5-7 years ago at the London Health Sciences Centre, University Hospital by Dr. Kiaii.

Exclusion Criteria:

- Patients not described above
