Part 1: Academic Journey and Research Focus
1. Could you briefly introduce your academic background and current main research interests? And what specific research area have you been focusing on recently, along with any breakthroughs or progress achieved in this area?
My academic journey has been shaped by a longstanding commitment to advancing coronary surgery through both clinical innovation and rigorous scientific inquiry. I completed my formal surgical training with a focus on coronary revascularization, and over the years, I have been privileged to work in environments that encouraged both high-volume clinical practice and meaningful academic contribution. This dual exposure has allowed me to develop a research portfolio that is closely aligned with real-world clinical challenges.
My primary research interests center on coronary artery bypass grafting (CABG), particularly off-pump coronary artery bypass (OPCAB), graft patency, and long-term outcomes following different revascularization strategies. In recent years, I have focused intensively on the evolution of OPCAB techniques, the nuances of patient selection, and the long-term comparative effectiveness of surgical versus percutaneous revascularization. This has included work on understanding the mechanistic reasons behind graft failure, the role of anaortic techniques in stroke prevention, and the integration of OPCAB into hybrid revascularization strategies.
A key area of progress has been synthesizing the rapidly expanding evidence base into clinically meaningful insights—clarifying where OPCAB offers clear advantages, where its limitations lie, and how surgical techniques can be optimized to improve long-term outcomes. Through systematic reviews, meta-analyses, and collaborative research efforts, I have contributed to a more nuanced understanding of how surgical strategy influences survival, stroke risk, and the durability of revascularization. This work has helped inform contemporary practice patterns and has supported a more evidence-based approach to selecting the optimal revascularization modality for individual patients.
2. You have been selected for the global Top 2% Scientists list for five consecutive years, which reflects the sustained international impact of your research in the field. In your view, what would you attribute this consistent academic influence to in terms of the characteristics or commitments in your research work? For instance, is it due to a long-term, in-depth focus on specific clinical issues, or a distinctive methodological approach?
Being included in the global Top 2% Scientists list for five consecutive years is an honor, and I view it as a reflection not only of productivity but of consistency, focus, and relevance. If I were to identify the key factors behind this sustained academic influence, I would highlight three elements.
First, I have maintained a long-term, in-depth focus on a clearly defined set of clinical questions. Coronary revascularization—particularly OPCAB—has been an area of both passion and persistence for me. By concentrating on a specific domain over many years, I have been able to contribute work that builds on itself, deepens understanding, and remains clinically meaningful.
Second, I have always aimed to align my research with real clinical problems. Much of my work comes directly from the operating room and the bedside—questions about graft durability, stroke prevention, or technique refinement are not abstract academic exercises but issues that affect patient outcomes every day. This clinical grounding ensures that the research remains relevant and impactful.
Third, I place strong emphasis on methodological rigor and transparency. Whether conducting meta-analyses, synthesizing evidence, or evaluating long-term outcomes, I strive to ensure that the work is robust, reproducible, and clearly communicated. This commitment to quality has helped the research resonate internationally and remain influential over time.
Ultimately, I believe that sustained academic impact comes from a combination of focus, curiosity, and a genuine desire to improve patient care. The recognition is gratifying, but the real motivation continues to be advancing the field in ways that meaningfully benefit patients.
Part 2: Frontiers and Hot Topics in the Field
1. You have participated in multiple important research projects, such as the UK TAVI trial and AMBITION trial. Combining your research experience, what do you think are the current hotspots and key research directions in the field of cardiac surgery? How can The Heart Surgery Forum (HSF) better capture and reflect these cutting-edge trends?
Cardiac surgery is undergoing one of the most dynamic periods of transformation in its history. My involvement in major trials such as the UK TAVI trial and the AMBITION trial has reinforced how rapidly the boundaries between surgical and transcatheter therapies are evolving. Several key research directions stand out.
First, structural heart disease interventions continue to expand, with TAVI, transcatheter mitral repair/replacement, and emerging tricuspid technologies reshaping traditional surgical indications. Understanding long-term durability, patient selection, and the optimal integration of surgical and transcatheter approaches remains a central research priority.
Second, coronary surgery is entering a new era, driven by anaortic techniques, advanced conduit strategies, and the maturation of hybrid revascularization. There is growing interest in how surgical precision—whether through OPCAB, minimally invasive access, or robotic platforms—can be combined with PCI to create more individualized treatment pathways.
Third, perioperative optimization and enhanced recovery are becoming increasingly evidence-based. Research on frailty, myocardial protection, neurological outcomes, and organ-preservation strategies is reshaping how we define “success” beyond survival alone.
Finally, data science and artificial intelligence are emerging as powerful tools for risk prediction, imaging interpretation, and intraoperative decision-making. Their integration into cardiac surgery is still in its early stages but represents a major frontier.
For The Heart Surgery Forum, the opportunity lies in being a platform that not only reports these developments but contextualizes them. HSF can amplify its impact by prioritizing rapid publication of emerging techniques, inviting expert perspectives on evolving technologies, and fostering dialogues between surgeons, interventionalists, and imaging specialists. By doing so, the journal can remain at the forefront of the field’s most important conversations.
2. As the guest editor of HSF's special issue "Updates and Challenges in Coronary Surgery", this issue covers 16 key topics ranging from graft selection to reoperative CABG and surgical training. How did you determine these topics during the planning process? Were they derived from unresolved dilemmas you observed in clinical practice or trends in frontier research?
The 16 topics included in the special issue were chosen through a deliberate process that combined clinical relevance, scientific momentum, and the practical challenges faced by surgeons worldwide. Many of these themes—such as graft selection, anaortic OPCAB, reoperative CABG, and training—reflect persistent dilemmas that clinicians encounter daily. Others, such as hybrid revascularization and minimally invasive techniques, represent areas where innovation is outpacing widespread adoption, creating a gap between what is possible and what is routinely practiced.
In planning the issue, I aimed to strike a balance between long-standing controversies and emerging frontiers. The goal was to create a resource that not only summarizes current evidence but also highlights where further research is urgently needed. The topics were therefore derived from both clinical observation and the trajectory of contemporary research—areas where new data are rapidly accumulating, yet consensus remains elusive.
Ultimately, the special issue was designed to serve as a roadmap for the future of coronary surgery, identifying the questions that matter most and the areas where progress will have the greatest clinical impact.
3. This special issue focuses on hot topics such as "minimally invasive and robotic CABG" and "hybrid coronary revascularization". In your opinion, what are the main bottlenecks restricting the clinical popularization of these innovative technologies? What breakthroughs are expected in the next 5–10 years to promote their development?
Minimally invasive and robotic CABG, along with hybrid coronary revascularization, represent some of the most promising innovations in the field. However, several bottlenecks continue to limit their widespread adoption.
The first challenge is technical complexity and the steep learning curve. Robotic and minimally invasive CABG require specialized training, dedicated teams, and consistent case volumes—conditions that are not universally available. This creates variability in outcomes and slows broader uptake.
Second, infrastructure and cost barriers remain significant. Robotic platforms and hybrid operating suites require substantial investment, and many institutions struggle to justify these costs without clear reimbursement pathways or high procedural volumes.
Third, evidence gaps persist, particularly regarding long-term outcomes and comparative effectiveness. While early results are promising, large-scale randomized data remain limited, and this affects guideline recommendations and institutional decision-making.
Looking ahead, several breakthroughs are likely to accelerate adoption over the next 5–10 years. Advances in robotic instrumentation, imaging integration, and automation will make procedures more reproducible and accessible. The expansion of structured training programs and simulation-based learning will help flatten the learning curve. Additionally, as hybrid revascularization becomes more standardized and supported by stronger evidence, it is likely to be embraced as a mainstream strategy rather than a niche approach.
In combination, these developments will help shift innovative coronary techniques from specialized centers to broader clinical practice, ultimately improving patient choice and outcomes.
