Summary
Valve replacement in patients with enlarged hearts (cardiac-thoracic rate > 0.80) is feasible. Survivors showed improved heart function, highlighting the importance of pre- and postoperative management for myocardial preservation.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Enlarged heart, defined by a cardiac-thoracic (C/T) rate greater than 0.80, traditionally contraindicates valve replacement surgery.
- Limited data exists on the outcomes of cardiac valve interventions in this patient population.
Purpose of the Study:
- To evaluate the feasibility and outcomes of valve replacement and repair in patients with significantly enlarged hearts (C/T rate > 0.80).
- To identify key factors for successful surgical management in this high-risk group.
Main Methods:
- Retrospective analysis of 18 patients with enlarged hearts (C/T rate 0.81-0.97) undergoing cardiac valve surgery.
- Procedures included mitral valve replacement (11 patients), aortic valve replacement (2 patients), and tricuspid valvuloplasty (5 patients).
Main Results:
- One perioperative death occurred due to low cardiac output.
- The remaining 17 patients demonstrated improved cardiac function, with New York Heart Association (NYHA) classification improving from III or IV to II postoperatively.
- Successful valve intervention was achieved in the majority of patients.
Conclusions:
- Cardiac valve surgery in patients with enlarged hearts is achievable.
- Aggressive pre- and postoperative management strategies focused on preserving myocardial function are crucial for successful outcomes.
- Careful preoperative assessment and surgical technique are vital for managing patients with huge hearts undergoing valve surgery.
