Summary
This report details the first port-access double valve replacement (DVR) in Japan for mitral and aortic valve stenosis. The minimally invasive procedure resulted in an uneventful recovery and sinus rhythm restoration.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Procedures
- Cardiac Arrhythmia Management
Background:
- Severe mitral and aortic valve stenosis often necessitates complex surgical intervention.
- Atrial fibrillation is a common comorbidity in patients with valvular heart disease.
- Traditional open-heart surgery carries significant risks and prolonged recovery times.
Observation:
- A 57-year-old male patient presented with symptomatic mitral and aortic valve stenosis and atrial fibrillation.
- The patient underwent a complex cardiac procedure involving double valve replacement and maze procedure.
- The surgery was performed using a minimally invasive port-access technique.
Findings:
- Successful double valve replacement (DVR) with bioprostheses and maze procedure was achieved.
- The port-access technique facilitated the complex cardiac surgery.
- The patient experienced an uneventful postoperative recovery, maintaining a consistent sinus rhythm.
- Hospital discharge occurred 22 days post-surgery.
Implications:
- This case demonstrates the feasibility and safety of port-access DVR in Japan.
- Minimally invasive cardiac surgery may offer advantages in terms of recovery for complex valve procedures.
- Further research into port-access techniques for DVR is warranted to expand its clinical application.
