Summary
This High Court decision concerns a claim in medical negligence brought by the administratrix of the estate of the late Milakov Steven (“MS”) against Dr Tong Ming Chuan, a cardiothoracic surgeon. Dr Tong performed a redo coronary artery bypass graft (“redo-CABG”) on MS on 12 March 2007, approximately seven weeks after MS had undergone an initial triple CABG. MS died on 23 April 2007 from post-operative complications. The trial was confined to liability, meaning the court focused on whether Dr Tong breached the applicable standard of care and whether that breach caused MS’s death.
The case is significant because it required the court to evaluate not only the surgical act itself, but also the adequacy of medical advice and treatment selection in a high-risk clinical scenario. The court examined the medical background, including MS’s prior coronary artery disease, the first major adverse cardiac event (“MACE”) in January 2007, the subsequent acute myocardial infarction (“AMI”) in March 2007, and the angiographic findings suggesting occlusion of two grafts. A central theme was whether the redo-CABG was indicated and appropriate, and whether Dr Tong provided sufficient and proper advice regarding risks and alternatives.
What Were the Facts of This Case?
MS was born on 19 July 1951 and was 65 years old at the time of his death. He was an American citizen holding permanent residence status in Singapore. MS had a history of borderline diabetes and hypertension, but the evidence indicated that before his first major adverse cardiac event he was in good health and maintained an active lifestyle, exercising five to six times a week. MS was married to the plaintiff, D’Conceicao Jeanie Doris, and had two other next-of-kin: a daughter, Stacey Anne Moody (a US citizen), and a son, Tim Milakov (also a US citizen). Letters of Administration were granted to the plaintiff on 22 March 2010, extracted on 15 April 2010.
Dr Tong was a consultant cardiothoracic surgeon in private practice with more than 28 years of experience. He practised at a clinic in Mount Elizabeth Medical Centre. MS first saw Dr Tong on 9 March 2007 after being referred by an interventional cardiologist, Dr Christopher Chew, who had assessed MS following an acute deterioration. The events leading to the claim began earlier in Houston, USA, where MS experienced left-side back tightness with nausea during routine exercise on 17 January 2007. He was taken to St Joseph Medical Centre (“SJMC”), where he was diagnosed with ischaemia and angina pectoris. Importantly, the evidence clarified that MS did not suffer an acute myocardial infarction on 17 January 2007; this was his first MACE.
On 18 January 2007, MS underwent coronary angiography. The angiogram revealed coronary artery disease with stenosis in multiple vessels: the left main coronary artery (“LMCA”), the left anterior descending arterial system (“LAD”), the circumflex artery (“Cx”), and the right coronary arterial system (“RCA”). Based on his doctors’ advice, MS underwent a triple CABG on 19 January 2007 (“the initial CABG”). The initial CABG involved three grafts: (1) a saphenous vein graft from the aorta to a marginal branch of the Cx (“Graft 1”); (2) a saphenous vein graft from the aorta to another marginal branch of the Cx (“Graft 2”); and (3) a left internal mammary artery graft to the LAD (“the LIMA-LAD graft”). After the initial CABG, MS recovered well and returned to Singapore in February 2007.
Upon returning to Singapore, MS consulted his general practitioner, Dr Michael Chua, who recommended cardiology follow-up. MS saw Dr Christopher Chew on 23 February 2007. Tests were within acceptable ranges, and Dr Chew advised that MS was recovering well and could continue his usual exercises and lifestyle, although MS adopted a more sedentary routine due to medical leave. The next turning point occurred at around 5.00am on 9 March 2007, when MS experienced chest pain and presented to the Accident and Emergency Department at Mount Elizabeth Hospital (“MEH”) around 6.00am, requesting to see Dr Chew. It was not disputed that MS suffered an AMI on 9 March 2007, described as his first AMI.
Dr Chew examined MS and performed a coronary angiography at about 8.45am on 9 March 2007. The angiogram suggested that Graft 1 and Graft 2 were completely occluded, and the catheterisation report described a “total block” in those grafts. This occlusion meant that blood could not flow through the grafts, depriving downstream heart muscle of oxygen and nutrients. There was a dispute at trial regarding the patency of the LIMA-LAD graft, which became relevant to whether redo-CABG was indicated. Dr Chew recommended a surgical opinion from a cardiothoracic surgeon and referred MS to Dr Tong. Dr Tong examined MS at about noon on 9 March 2007 and proposed the option of a redo-CABG. The sufficiency of the advice given by Dr Tong regarding risks and alternative treatments was disputed.
On 12 March 2007, Dr Tong performed the redo-CABG on MS. The court accepted that a redo-CABG is essentially similar to an initial CABG but is substantially riskier, especially when performed within a short period after the initial surgery. The evidence explained that after an initial CABG, the heart and surrounding tissues require time to recover. There would be scarring and adhesions between the heart and pericardium and between the pericardium and the breastbone. The closer the redo surgery is to the initial operation, the more vascularised the scar tissue and incision sites become, increasing blood loss. The court also noted that surgeons must proceed slowly and cauterise carefully to manage this heightened risk. MS died on 23 April 2007, about six weeks after the redo-CABG, from post-operative complications.
What Were the Key Legal Issues?
The principal legal issues were framed around medical negligence in tort. First, the court had to determine the applicable standard of care for a cardiothoracic surgeon in Dr Tong’s position, including how that standard applies to surgical decision-making and peri-operative management. Second, the court had to assess whether Dr Tong breached that standard in relation to the medical advice, care and treatment he rendered to MS between 9 March 2007 and 23 April 2007.
Within that overarching question, the case turned on whether the redo-CABG was indicated and appropriate based on MS’s clinical condition and angiographic findings, particularly in light of the disputed patency of the LIMA-LAD graft. The court also had to consider whether Dr Tong provided adequate advice about the risks of redo-CABG and the availability of alternative treatments. In medical negligence claims, the adequacy of advice can be relevant both to whether the treatment chosen was reasonable and to whether the patient was properly informed to consent to the procedure, depending on how the pleadings and evidence are structured.
Finally, because the trial was confined to liability, the court’s focus was on breach rather than quantum. Nevertheless, causation is often intertwined with liability analysis in negligence cases, and the court would have had to consider whether any breach was causally connected to MS’s death from post-operative complications, at least at the liability stage.
How Did the Court Analyse the Issues?
The court approached the matter by first setting out the medical timeline and defining key terms such as ischaemia, angina pectoris, AMI, coronary angiography, and CABG. This was necessary because the dispute was not simply about whether surgery was performed, but about whether the clinical indications justified a redo operation so soon after the initial CABG. The court accepted that the first MACE in January 2007 involved ischaemia and angina without an AMI, whereas the second MACE in March 2007 involved an AMI. This distinction mattered because it affected the urgency and severity of the clinical picture at the time Dr Tong advised and operated.
On the angiographic findings, the court noted that it was undisputed that Graft 1 and Graft 2 were completely occluded on 9 March 2007. The occlusion explained the AMI mechanism: reduced blood flow to heart muscle downstream of the occluded grafts. However, the patency of the LIMA-LAD graft was disputed. The court treated this as a potentially critical factor because the presence or absence of a functioning graft supplying the LAD territory could influence the risk-benefit analysis of redo-CABG versus other options. If the LIMA-LAD graft remained patent, the clinical urgency and the extent of revascularisation required might differ; if it was occluded, the need for surgical revascularisation could be more compelling.
In analysing whether redo-CABG was indicated, the court also considered the timing. The redo-CABG was performed about seven weeks after the initial CABG. The court accepted that this timing increased surgical risk due to scarring, adhesions, and the likelihood of heavier blood loss. This meant that a surgeon proposing redo-CABG so soon after the initial operation would need to justify the decision with sound clinical reasoning and appropriate patient counselling. The court’s reasoning therefore necessarily involved evaluating whether Dr Tong’s decision-making fell within the range of acceptable practice for a competent cardiothoracic surgeon.
The court also addressed the disputed issue of advice. The evidence indicated that Dr Tong proposed redo-CABG at the first meeting on 9 March 2007. The sufficiency of the advice given by Dr Tong regarding risks and alternative treatments was contested. In medical negligence litigation, the adequacy of advice can be relevant to whether the surgeon took reasonable steps to inform the patient of material risks and options, and whether the chosen treatment was a reasonable one in the circumstances. The court would have assessed what risks were known or foreseeable, how they compared with alternatives, and whether the patient was given a fair and proper explanation to enable an informed decision.
Although the excerpt provided does not include the later portions of the judgment, the structure of such liability analysis typically involves: (1) identifying the standard of care; (2) determining what a competent surgeon would have done in similar circumstances; (3) comparing that with Dr Tong’s conduct; and (4) assessing whether any departure caused the harm complained of. Given that the trial was confined to liability, the court’s conclusion would have focused on whether the plaintiff established breach on the balance of probabilities, and whether the alleged breaches were legally causative of MS’s death.
What Was the Outcome?
The provided extract does not include the court’s final findings on liability or the orders made. Accordingly, based solely on the text available, the precise result (whether Dr Tong was found liable or not, and what specific breaches were accepted or rejected) cannot be stated with confidence.
However, the case proceeds as a High Court medical negligence action in which liability was tried first, and the court’s determination would have set the foundation for any subsequent assessment of damages (if liability was established) or for dismissal (if liability was not proven).
Why Does This Case Matter?
This decision is important for practitioners because it illustrates how Singapore courts evaluate medical negligence claims in complex surgical contexts, particularly where the dispute concerns clinical indications and the adequacy of advice. Redo-CABG performed shortly after an initial CABG is inherently high-risk. The case therefore highlights that the standard of care may require careful justification of the decision to operate, especially when the timing increases the likelihood of complications such as significant blood loss.
For lawyers and law students, the case also demonstrates the evidential significance of angiographic findings and their interpretation. Where key anatomical or functional facts are disputed—such as the patency of a graft—those disputes can become central to whether the chosen treatment was reasonable. The case underscores that medical negligence litigation often turns on expert evidence and on how the court resolves competing medical narratives.
Finally, the case is relevant to the statutory framework for claims by dependants and estates under the Civil Law Act. The plaintiff sued for the benefit of dependants under ss 20 and 21 and for the benefit of the estate under s 10. This statutory context affects standing and the categories of recoverable loss, and it is therefore useful for practitioners assessing both liability and the structure of claims in fatal injury cases.
