The optimal treatment of multivessel coronary artery disease

The practice of percutaneous coronary intervention has overtaken coronary bypass surgery in the treatment of ischaemic heart disease. Several randomized controlled as well as registry and observational trials have addressed the issue of patient selection and outcomes in order to provide the cardiologist with data enabling optimal treatment selection. This article reviews the major trials performed over the past 25 years, underscoring their strengths and limitations and draws on lessons and guidelines that are relevant to our local practice.peer-reviewe

Evaluating a trainee’s progress in surgical dexterity

The local cardiac surgical training program is modelled on a one-to-one apprenticeship encompassing a number of years. Trainee progress is regularly audited and work of increasing complexity is provided, commensurate with the trainee's ability. Speed and accuracy are desirable surgical goals and reflect a high level of decision-making and dexterity. The trainee's surgical speed over a period of time was monitored as one measure of progress. The mean time required to complete a coronary anastomosis (graft time) decreased from 12.8±1.9minutes in the first year of training to 9.0±1.9minutes in year four, inter-group variance (ANOVA) was highly significant from year two to year three and from year three to year four (p<0.001). Risk stratification was utilised in the selection of patients for the trainee. Parsonnet score increased from 5.1±3.5 in year one to 6.0±5.0 in year four. Similarly, EuroSCORE increased from 2.1±1.8 to 2.4±2.1. Additionally, variable life-adjusted display (VLAD) plots were constructed in order to provide a visual representation of performance against predicted outcome by EuroSCORE. Successive VLAD plots demonstrate the changing practice of the trainee as it came to resemble more closely that of his instructor and this was achieved without jeopardising patient outcome.peer-reviewe

Why audit?

Decision making in surgery is based on contemporary hard data describing outcomes in a particular patient population. As a professional body, with powers of self regulation and peer review, we need to be cognisant of the expected norm of practice. This can only be derived from information that is shared amongst our colleagues both locally and abroad. We have the responsibility to contribute to this database by way of audit in a rigourous and honest fashion and to utilise it routinely in the management of our patients.peer-reviewe

Coronary artery bypass surgery in the elderly : is it worthwhile?

Objectives: To evaluate the early outcomes after coronary surgery in the elderly. Methods: A retrospective analysis (April 1995- January 2012) of mortality, morbidity and hospital stay, derived from a single surgeon’s practice. Outcomes of patients over 70 (group A, n=785) were compared with those of controls under 70 (group B, n=2772). Results: Intervention rate was significantly higher (1502/106 vs 467/106, p<0.0001). There were significantly fewer single and quintuple grafts, and significantly more double grafts in group A. The use of an internal thoracic artery (ITA) was lower in group A (748/785, 95.3% vs 2695/2772, 97.2%, p=0.006). Mortality for the entire coronary surgical practice was 1.2%. The overall mortality was 2.7% in group A and 0.8% in group B (p<0.0001). Freedom from any post- operative complication occurred in 57.7% in group A and in 75.6% in group B (p<0.0001). Cardiac complications (except for perioperative MI and atrial flutter) were significantly higher in group A, as were major neurological, renal and respiratory complications, as well as minor wound complications. All complications resulted in patient morbidity but cerebrovascular accident had the worst impact, contributing to perioperative death in 8 of the 18 cases ingroupAandin4ofthe24casesingroupB (p=0.049). Average length of stay on intensive care was similar (1.19±1.84 days for group A and 1.13±1.48 days for group B, p=0.38). The average HDU stay was longer in group A (1.43±2.70 vs 0.95±3.68 days, p=0.006) as was the average ward stay (4.00±3.33 vs 3.25±2.23 days, p<0.0001). Conclusions: Although mortality and morbidity remain significantly higher, taken in the context of the overall clinical problem, cardiac surgery has much to offer in this select group of patients.peer-reviewe

Sir Charles Ballance : A pioneer surgeon in Malta

Charles Ballance was arguably the most eminent surgeon stationed in Malta during the Great War. On the 16th February 1918 he removed a bullet from the heart of trooper Robert Martin who was shot in the chest in Salonika three months previously. Sadly the patient died of sepsis one month later, a fact that obscured the importance of this landmark operation, the third of its kind worldwide. This paper sets the background to this achievement and celebrates the impact that this surgical pioneer left on our shores.peer-reviewe
