Overview
Prosthetic cardiac valve dehiscence refers to the separation or loosening of a prosthetic valve from its surrounding tissue, often necessitating urgent intervention due to potential hemodynamic instability and increased morbidity and mortality 1.Diagnosis
Clinical signs include hemodynamic instability, new or worsening murmur, and signs of endocarditis 1.
Imaging studies such as transesophageal echocardiography (TEE) are crucial for definitive diagnosis 1.
Grading systems often correlate severity with hemodynamic compromise and surgical urgency 1.Management
Immediate surgical intervention is typically required for significant dehiscence 1.
Temporary mechanical support devices may be used preoperatively in hemodynamically unstable patients 1.
Antibiotic therapy is indicated if infective etiology is suspected 1.Special Populations
Elderly: Older adults with debility may have slower functional recovery post-intervention; rehabilitation outcomes suggest lower discharge home rates and potentially prolonged recovery periods 1.Key Recommendations
Perform transesophageal echocardiography for definitive diagnosis of prosthetic valve dehiscence (Evidence: Strong 1).
Initiate urgent surgical repair or replacement for significant cases of valve dehiscence (Evidence: Strong 1).
Consider inpatient rehabilitation with caution in elderly patients due to potentially slower recovery and lower likelihood of home discharge (Evidence: Moderate 1).References
