Total Cardiovascular Surgeries — Annual Trend (2016–2023)
Surgical Volume (2023)
All figures reflect procedures performed by the Cardiovascular Surgery Department in 2023.
Open-Heart Surgery
| Procedure | Cases | Notes |
|---|---|---|
| Open-heart surgeries (total) | 310 | Emergency / urgent: 128 cases (41.2%) |
| Isolated CABG | 94 | Off-pump rate: 83% (78/94) |
| Isolated valve surgery | 62 | Including MAZE and left atrial appendage ligation where combined |
| — Aortic valve replacement | 23 | MICS: 16 cases (73% of primary AVR) |
| — Mitral valve repair | 19 | MICS: 18 cases (95% of primary mitral valve repair) |
| — Mitral valve replacement | 10 | MICS: 4 cases (50% of primary mitral valve replacement) |
| — Combined valve (≥2 valves) | 10 | |
| Isolated aortic surgery (open) | 90 | Emergency / urgent: 62 cases (68.9%) |
| Combined procedures | 48 | CABG + valve, valve + aorta, CABG + aorta, etc. |
| Other cardiac surgery | 16 | ASD, LV rupture, pulmonary thrombectomy, LV thrombus, etc. |
Endovascular & Other Procedures
| Procedure | Cases | Notes |
|---|---|---|
| TEVAR | 50 | Emergency / urgent: 15 cases (30.0%) |
| EVAR | 47 | Emergency / urgent: 10 cases (21.3%) |
| Abdominal aortic aneurysm (open repair) | 49 | Including common iliac aneurysm; emergency: 6 cases |
| Peripheral vascular surgery | 46 | Bypass, thrombectomy, and other procedures; emergency: 21 cases (45.7%) |
| Other (shunt creation, etc.) | 72 | |
| Other thoracic surgery | 29 | |
| Total cardiovascular surgeries | 734 |
Robotic MICS — Annual Volume (2016–2023)
Minimally invasive cardiac surgery using the da Vinci surgical system,
performed fully endoscopically without sternotomy.
The robotic MICS programme was established in 2018, with procedural volume increasing steadily thereafter.
Robotic MICS — Annual Volume (2016–2023)
2023 MICS Volume
- 40 total robotic MICS procedures
- AVR: 16 cases — 73% of primary AVR performed as MICS
- Mitral repair: 18 cases — 95% MICS rate
- MVR: 4 cases — 50% of primary MVR performed as MICS
- ASD closure: 2 cases — all performed as MICS
For international patients
- Robotic MICS is available as a self-funded (private pay) option
- No sternotomy — smaller incisions and faster recovery
- Performed by Dr. Kuroyanagi — all procedures fully endoscopic
- Surgery can typically be scheduled within one week of consultation
Emergency Surgery
A significant proportion of cardiovascular surgery at this hospital is performed under emergency or urgent conditions.
24/7 surgical readiness is maintained throughout the year.
Emergency / Urgent Cases by Category (2023)
| Category | Emergency / Urgent | Rate |
|---|---|---|
| Open-heart surgery (total) | 128 | 41.2% |
| Isolated CABG | 42 | 42.6% |
| Isolated valve surgery | 4 | 6.5% |
| Isolated aortic surgery (open) | 62 | 68.9% |
| — Acute aortic dissection (Stanford type A) | 65 | 100% — all emergency cases |
| Combined procedures | 11 | 22.9% |
| TEVAR | 15 | 30.0% |
| EVAR | 10 | 21.3% |
| Peripheral vascular surgery | 21 | 45.7% |
Core Capabilities
Robotic & Minimally Invasive
- Fully endoscopic MICS (da Vinci) — no sternotomy
- AVR, mitral repair/replacement, and ASD closure via MICS
- Growing programme since 2018
Complex & Emergency
- Acute aortic dissection (Stanford type A) — 24/7 response
- Emergency CABG, valve, and aortic surgery
- Off-pump CABG rate 83%
Endovascular Aortic
- TEVAR — thoracic aortic aneurysm and dissection
- EVAR — abdominal aortic aneurysm
- Open aortic repair for complex anatomy
