Summary
This High Court decision concerns a claim in medical negligence and breach of contract arising from the death of Milakov Steven (“MS”) following a redo coronary artery bypass graft (“redo-CABG”) performed by cardiothoracic surgeon Tong Ming Chuan (“Dr Tong”). The plaintiff, acting as administratrix of MS’s estate, sued in tort and contract alleging that Dr Tong was negligent and/or breached contractual duties in relation to the medical advice, care, and treatment rendered to MS during the period from 9 March 2007 to 23 April 2007. The trial was confined to liability.
At the heart of the case was whether Dr Tong’s clinical decision-making and advice—particularly the recommendation and performance of a redo-CABG shortly after an earlier CABG—met the applicable standard of care. The court also had to assess causation and whether any alleged breach of duty was causally linked to MS’s subsequent post-operative complications and death. The judgment ultimately addresses the evidential and expert-driven nature of medical negligence litigation, including how courts approach disputes over clinical indications, risks, and alternative treatment options.
What Were the Facts of This Case?
MS was a 65-year-old American citizen with permanent residence status in Singapore. He had a history of borderline diabetes and hypertension but, prior to his first major adverse cardiac event (“MACE”) in January 2007, he was described as being in good health and maintaining an active lifestyle, exercising regularly. MS was engaged on a contractual basis by Chevron Inc in the United States as a consultant on communication skills, brand management, and public relations, and he was also an author of books and articles. His average monthly earnings were around $16,250 at the time of his death.
On 17 January 2007, while in Houston, USA, MS experienced left-side back tightness with nausea during his routine physical exercise. He was diagnosed at St Joseph Medical Centre (“SJMC”) with ischaemia and angina pectoris. Importantly, the court record emphasises that this was not an acute myocardial infarction (“AMI” or “heart attack”) at that time; it was the first MACE. Coronary angiography on 18 January 2007 revealed significant coronary artery disease with stenosis in multiple vessels, including the left main coronary artery, the left anterior descending system, the circumflex artery, and the right coronary arterial system.
Following SJMC’s 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 circumflex artery (“Graft 1”); (2) a saphenous vein graft from the aorta to another marginal branch of the circumflex artery (“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.
In Singapore, MS consulted his general practitioner, who recommended cardiology follow-up with an interventional cardiologist, Dr Christopher Chew at Mount Elizabeth Medical Centre. On 23 February 2007, Dr Chew conducted tests that fell within acceptable ranges and advised that MS was recovering well and could continue his usual exercises and lifestyle, although MS adopted a more sedentary lifestyle due to medical leave. The next critical event occurred on 9 March 2007, when MS suffered chest pain and presented to the Accident and Emergency Department at Mount Elizabeth Hospital (“MEH”). It was not disputed that MS suffered an AMI that day, the first AMI of his clinical course.
What Were the Key Legal Issues?
The principal legal issues were whether Dr Tong owed and breached a duty of care in the diagnosis, advice, and treatment of MS, and whether any breach caused MS’s death. In medical negligence claims, the court must determine the applicable standard of care: what a reasonably competent practitioner in the same field would have done in the circumstances. Here, the dispute focused on the sufficiency of Dr Tong’s advice regarding the risks of a redo-CABG and alternative treatment options, as well as the appropriateness of proceeding with a redo-CABG so soon after the initial CABG.
A second key issue concerned clinical indication and risk assessment. A redo-CABG is described as essentially similar to an initial CABG but “much riskier,” particularly when performed within a short period after the first surgery. The court record highlights that scarring, adhesions, and vascularised scar tissue increase the likelihood of heavier blood loss and other complications. The legal question was whether Dr Tong’s recommendation and performance of the redo-CABG fell within the range of acceptable professional judgment, or whether it represented negligent decision-making.
Finally, the court had to address causation in a complex clinical setting. Even if the court found a breach, the plaintiff still needed to show that the breach was causally linked to the post-operative complications and death. Medical negligence cases often involve competing expert views on what would likely have happened had different advice or treatment been offered, and the court must evaluate these with careful attention to the evidence.
How Did the Court Analyse the Issues?
The court began by setting out the medical and procedural background necessary to evaluate liability. The judgment underscores that, for liability, it is essential to understand the sequence of cardiac events and the clinical reasoning behind treatment choices. The court accepted that MS’s AMI on 9 March 2007 was associated with occlusion of the earlier grafts. Specifically, after Dr Chew examined MS and performed coronary angiography around 8.45am on 9 March 2007, it was not disputed that the angiogram suggested that Graft 1 and Graft 2 were completely occluded, described in the report as a “total block.” The occlusion meant that blood flow through those grafts was cut off, depriving downstream heart muscle of oxygen and nutrients.
However, the record also shows that there was a substantial dispute at trial regarding the patency of the LIMA-LAD graft. This mattered because the clinical significance of graft occlusion and the remaining blood supply to the heart would affect whether redo-CABG was indicated, and what alternative options might be available. The court’s analysis therefore required it to weigh expert evidence on the state of the coronary circulation and the implications for surgical planning.
Dr Tong first 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 on the risks of redo-CABG and on alternative treatment options was disputed. The court’s approach in such cases typically involves examining whether the doctor’s conduct aligned with the standard of care expected of a competent cardiothoracic surgeon, including the duty to provide adequate information about material risks and reasonable alternatives. While the extract provided does not include the court’s full discussion, the structure of the case indicates that the court would have analysed both the content of the advice and the reasonableness of the decision to proceed.
In evaluating whether the redo-CABG was indicated and appropriate, the court considered the heightened risk profile of operating shortly after an initial CABG. The judgment explains that after an initial CABG, the heart and surrounding tissues require time to recover; there is scarring and adhesions between the heart and pericardium and between the pericardium and the breastbone. The closer the time to the initial surgery, the more vascularised the scar tissue and incision become, increasing blood loss risk. The court would therefore have assessed whether Dr Tong’s decision reflected a careful balancing of the urgency of revascularisation against the elevated surgical risks, and whether the evidence supported that balance as a reasonable professional judgment rather than negligent overtreatment.
On causation, the court would have examined the relationship between any alleged breach and the eventual post-operative complications that led to MS’s death on 23 April 2007, about six weeks after the redo-CABG. The plaintiff’s case necessarily required showing that the complications were not merely unfortunate outcomes but were linked to the alleged negligence—whether through inadequate advice leading to an uninformed consent decision, through negligent surgical technique, or through negligent peri-operative management. Conversely, the defendant’s case would have emphasised that the complications were within known risks of the procedure and that the clinical decision-making was within acceptable standards given the patient’s condition.
What Was the Outcome?
The trial was confined to liability, meaning the court’s determination addressed whether Dr Tong was liable for negligence and/or breach of contract. The practical effect of the outcome is that, depending on the court’s findings, the matter would proceed to damages (if liability was established) or be dismissed (if liability was not established). The case is therefore significant not only for its substantive medical negligence analysis but also for how it structures the litigation by separating liability from quantum.
Based on the judgment’s focus and the framing of the trial, the outcome would have turned on the court’s evaluation of expert evidence regarding (i) the standard of care for advising and recommending redo-CABG in the immediate post-initial-CABG period, and (ii) whether any breach was causally connected to MS’s death. For practitioners, the case illustrates that liability in medical negligence often depends on nuanced clinical facts—such as graft patency and the availability and suitability of alternatives—rather than on hindsight assessments of what ultimately occurred.
Why Does This Case Matter?
This decision is useful for lawyers and law students because it demonstrates how Singapore courts approach medical negligence claims where the alleged breach concerns clinical judgment and patient advice rather than a straightforward error. The case highlights that, in cardiothoracic surgery contexts, the standard of care is assessed against what a reasonably competent specialist would do, taking into account the urgency of the patient’s condition, the risks inherent in the procedure, and the existence of alternative treatment pathways.
From a litigation strategy perspective, the case underscores the importance of expert evidence on clinical indication and causation. Where there are disputes over key medical facts—such as the patency of a graft and the significance of occlusions—those disputes can be determinative of both liability and causation. The court’s emphasis on defining medical terms and setting out the sequence of events reflects the evidential complexity typical of medical negligence trials.
Finally, the case matters for practitioners dealing with claims brought by dependants and estates under the Civil Law Act. The plaintiff’s standing as administratrix and the statutory basis for damages for dependants and for the estate show how wrongful death and related claims are structured in Singapore. Even though the trial here was limited to liability, the statutory framework shapes the parties’ interests and the way damages will ultimately be assessed.
