Minimal access coronary revascularisation without cardiopulmonary bypass--the impact of robotic technology in the current clinical practice.
Recent advances in interventional cardiology and cardiac surgery have changed the traditional therapeutic algorithms by altering indications, timing and patterns of referral for subsequent surgical treatment. The traditional longitudinal sternomy incision has been the surgical approach of choice for multi-vessel coronary revascularisation. Drawbacks of this incision include potential postoperative morbidity, which translates to a prolonged postoperative length of stay. The combination of minimally invasive direct coronary artery bypass (MIDCAB) with percutaneous transluminal coronary angioplasty (PTCA) or stenting (a hybrid approach) is an alternative therapeutic method for patients with multivessel coronary artery disease. Recent advances in percutaneous interventions have attempted to address the problem of re-stenosis, initially through the deployment of bare metal intra-coronary stents and, more recently, with drug-eluting stents. Developments in coronary revascularisation have focused on reducing both surgical invasiveness and trauma. Patients with significant co-morbid pathologies, the ones undergoing re-interventions, and especially the elderly may benefit from such hybrid procedures by avoiding cardiopulmonary bypass and midline sternotomy. Minimally invasive techniques have revolutionized cardiothoracic surgery by increasing patient satisfaction and by reducing surgical trauma, hospital stay and consequently overall costs. There are however limitations. Robot assisted surgery endeavours to minimise these technical hindrances and so allow better and more accurate surgical practice whilst minimising surgical trauma.
