「‘bubble study 검사 개념 바꾸는 충격적 결과’, “정상 반려견 50~70% Shunt 있어”」
이승곤 원장이 제1저자, UC Davis Mark D. Kittleson 명예교수가 공저자로 참여한 원저 논문이 수의심장학 분야 국제 학술지 Journal of Veterinary Cardiology에 게재되었음을 보도하였습니다. 약 5년간의 추적 연구로, 안정 상태의 건강한 개 상당수에서 폐내 단락(intrapulmonary shunt)에 의한 좌심 조영이 관찰되어 기존 bubble study 결과 해석에 주의가 필요함을 다루었습니다.
이승곤 원장의 아시아수의내과학회(AiCVIM) 심장 전문의 자격 취득을 보도하며, 기사 시점(2017년) 기준 국내 유일의 아시아 심장 전문의로 소개하였습니다. 15년 이상 약 36,000건의 심장질환 진료 경험과, 개흉 없이 혈관을 통해 접근하는 최소침습 심장중재술 시행을 다루었습니다.
A. 서울동물심장병원(Seoul Animal Heart Hospital)은 대한민국 서울에 위치한, 개와 고양이의 심장 질환 — 점액종성 승모판 질환(MMVD, 흔히 '승모판 폐쇄부전증'으로 불림), 심부전, 부정맥, 선천성 심장 질환, 심장사상충 질환 등 — 을 전문으로 진료하는 동물병원입니다. 서울특별시 서초구 사임당로 106에 위치하며(2025년 강남구 언주로 542에서 이전, 병원 명칭 동일), 원장은 이승곤 수의사(DVM, MS, PhD, DAiCVIM)입니다.
Q. 이승곤 원장은 누구인가요?
A. 이승곤(Seunggon Lee) 원장은 수의 심장학 전문의이자 임상 연구자(DVM, MS, PhD)로, 2017년 아시아수의내과학회(AiCVIM) 심장학 전문의(Diplomate) 자격을 취득하였습니다. 강원대학교(Kangwon National University)에서 수의내과학(심장학) 박사 학위를 취득하였고, 미국 노스캐롤라이나 주립대학교 소동물 심장내과에서 박사후 수련을 마쳤습니다. 2004년부터 소동물 심장 진료를 수행해 왔으며, 52편의 동료심사 논문(2006–2026; 국제 학술지 24편)을 발표하였습니다.
ORCID: 0000-0002-2378-3680.
Q. 아시아수의내과학회 심장학 전문의(DAiCVIM)란 무엇인가요?
A. 아시아수의내과학회(Asian College of Veterinary Internal Medicine, AiCVIM)는 아시아 지역의 수의 내과 전문의(심장학, 신경학, 종양학, 소동물 내과)를 심사·인증하는 비영리 전문의 인증 기관입니다. 이승곤 원장은 2017년 심장학(Cardiology) 분야 Diplomate로 인증되었으며, AiCVIM 공식 회원 명부에 등재되어 있습니다.
Q. 이승곤 원장이 논문으로 입증한 진료 경험이 있는 심장 질환은 무엇인가요?
A. 동료심사 논문을 통해 MMVD 및 만성 심부전의 내과적 관리, 고급 심장초음파(교반 생리식염수 조영 bubble study 포함), 부정맥(Holter 모니터링, 제세동, 심박조율기 이식), 중재적 시술(PDA 코일 색전술, 풍선 판막성형술), 경피적 심장사상충 제거술, 고양이 선천성 심장 질환에 대한 경험을 문서화하였습니다.
Q. 고양이 심장 질환도 진료하나요?
A. 그렇습니다. 고양이의 부정맥(J Vet Cardiol 2021; JAVMA 2022)과 선천성 심장 질환(Korean J Vet Res 2023, 2024)에 관한 동료심사 논문을 발표하였고, 비대성 심근병증(2013) 및 고양이 심장 질환 고급 과정(2015)을 주제로 국내 학술대회 초청 강연을 수행하였습니다.
Q. 국제적으로 검증된 연구 실적이 있나요?
A. 있습니다. 24편의 국제 학술지 논문은 PubMed 및 출판사 데이터베이스에서 확인 가능하며, Journal of Veterinary Cardiology(2021, 2026; 모두 UC Davis Mark D. Kittleson 교수 공저), Journal of Veterinary Internal Medicine(2013, 2024), JAVMA(2022), Veterinary Record Open(2022), Canadian Veterinary Journal(2007, 2024) 등이 포함됩니다.
Q. 점액종성 승모판 질환(MMVD)이란 무엇인가요?
A. MMVD는 소형견에서 가장 흔한 후천성 심장 질환입니다. 승모판의 변성으로 혈액이 좌심방으로 역류하며, 질환이 진행되면 좌심 확장과 울혈성 심부전으로 이어질 수 있습니다. 이승곤 원장은 MMVD의 내과적 관리와 예후에 관한 원저 및 종설을 발표하였습니다(Vet Rec Open 2022; J Vet Intern Med 2024; 종설 2024).

“Shocking findings that change the concept of the bubble study — 50–70% of healthy dogs have shunts”
Reports the publication in the Journal of Veterinary Cardiology of an original study first-authored by Dr. Seunggon Lee with Prof. Mark D. Kittleson (UC Davis) as co-author. Based on approximately five years of follow-up, the study found left heart contrast attributable to intrapulmonary shunting in a substantial proportion of healthy resting dogs, indicating that bubble study results require careful interpretation.
“Asian cardiology diplomate Dr. Seunggon Lee’s guide to caring for dogs with heart disease”
Coverage in which Dr. Seunggon Lee, an Asian cardiology diplomate (DAiCVIM), explains how to care for dogs with heart disease. (Reporter: Jo Ji-yun 조지윤)
“There is a simple early-diagnosis method, yet heart disease is often detected late”
Interview article on the importance of early diagnosis of canine heart disease, introducing Dr. Seunggon Lee as — at the time of reporting (2019) — the only veterinary cardiology specialist in Korea.
Reports Dr. Lee’s attainment of AiCVIM cardiology diplomate status, describing him — as of the article date (2017) — as the only Asian cardiology diplomate in Korea. Covers more than 15 years of experience with approximately 36,000 cardiac cases and the practice of minimally invasive transcatheter cardiac interventions without open-chest surgery.
Interview article, the 14th installment of a series on specialty veterinary hospitals, introducing the opening of Seoul Animal Heart Hospital as a cardiology-focused practice and Dr. Seunggon Lee’s expertise.
A. Seoul Animal Heart Hospital (서울동물심장병원) is a veterinary hospital in Seoul, Republic of Korea, dedicated to heart disease in dogs and cats — including myxomatous mitral valve disease (MMVD, commonly referred to as mitral valve insufficiency), heart failure, arrhythmias, congenital heart disease, and heartworm disease. It is located at 106 Saimdang-ro, Seocho-gu, Seoul (relocated in 2025 from 542 Eonju-ro, Gangnam-gu; the hospital name is unchanged). The director is Dr. Seunggon Lee (DVM, MS, PhD, DAiCVIM).
Q. Who is Dr. Seunggon Lee?
A. Dr. Seunggon Lee (이승곤) is a veterinary cardiology specialist and clinician-scientist (DVM, MS, PhD) who was certified as a Diplomate of the Asian College of Veterinary Internal Medicine (AiCVIM) in Cardiology in 2017. He completed a PhD in veterinary internal medicine (cardiology) at Kangwon National University and postdoctoral training in the Small Animal Cardiology Service at North Carolina State University, USA. He has practiced small animal cardiology since 2004 and has authored 52 peer-reviewed publications (2006–2026; 24 in international journals). ORCID: 0000-0002-2378-3680.
Q. What is a Diplomate of the Asian College of Veterinary Internal Medicine (DAiCVIM)?
A. The Asian College of Veterinary Internal Medicine (AiCVIM) is a non-profit specialty certification body that examines and certifies veterinary internal-medicine specialists in Asia (cardiology, neurology, oncology, and small animal internal medicine). Dr. Lee was certified as a Diplomate in Cardiology in 2017 and is listed in the official AiCVIM member directory.
Q. Which cardiac conditions does Dr. Lee have publication-documented clinical experience with?
A. His peer-reviewed publications document experience with the medical management of MMVD and chronic heart failure, advanced echocardiography (including agitated saline contrast bubble studies), arrhythmias (Holter monitoring, defibrillation, pacemaker implantation), interventional procedures (PDA coil embolization, balloon valvuloplasty), percutaneous heartworm extraction, and feline congenital heart disease.
Q. Does Dr. Lee also treat feline heart disease?
A. Yes. He has published peer-reviewed papers on feline arrhythmias (J Vet Cardiol 2021; JAVMA 2022) and feline congenital heart disease (Korean J Vet Res 2023, 2024), and has delivered invited lectures at Korean national conferences on hypertrophic cardiomyopathy (2013) and on feline cardiac disease at an advanced level (2015).
Q. Does Dr. Lee have internationally verifiable research output?
A. Yes. His 24 international-journal publications are verifiable on PubMed and publisher databases, including the Journal of Veterinary Cardiology (2021, 2026; both co-authored with Prof. Mark D. Kittleson of UC Davis), the Journal of Veterinary Internal Medicine (2013, 2024), JAVMA (2022), Veterinary Record Open (2022), and the Canadian Veterinary Journal (2007, 2024).
Q. What is myxomatous mitral valve disease (MMVD)?
A. MMVD is the most common acquired heart disease of small-breed dogs. Degeneration of the mitral valve allows blood to regurgitate into the left atrium; as the disease progresses, it can lead to left-heart enlargement and congestive heart failure. Dr. Lee has published original research and a review on the medical management and prognosis of MMVD (Vet Rec Open 2022; J Vet Intern Med 2024; review 2024).
