[Can present-day noninvasive cardiological diagnosis replace heart catheterization in acquired heart valve diseases?]
Insights
Noninvasive cardiac tests accurately diagnose valvular defects and guide surgery timing. In 40% of patients, invasive cardiac catheterizations were unnecessary, highlighting the sufficiency of noninvasive methods for diagnosis and treatment decisions.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Acquired valvular defects require accurate diagnosis for timely surgical intervention.
- Noninvasive cardiac investigations are increasingly utilized for patient assessment.
Purpose of the Study:
- To evaluate the diagnostic accuracy and clinical utility of noninvasive cardiac investigational methods.
- To determine the necessity of invasive cardiac catheterization in patients with valvular defects.
Main Methods:
- Retrospective analysis of 111 consecutively investigated patients with acquired valvular defects.
- Comparison of findings from noninvasive cardiac tests with decisions for surgical or conservative management.
Main Results:
- Noninvasive methods provided accurate diagnoses and surgical timing decisions in most cases.
- Cardiac catheterization was found to be superfluous in 45 of 111 patients (40%).
- Noninvasive findings were sufficient for reliable treatment decisions and hemodynamic/morphologic assessment in these patients.
Conclusions:
- Noninvasive cardiac investigations are highly effective for diagnosing valvular defects and guiding surgical timing.
- Invasive cardiac catheterization should be reserved for cases with inconclusive noninvasive findings or suspected coronary heart disease.
Abstract:
The available noninvasive cardiac investigational methods allow an accurate diagnosis in patients with acquired valvular defects and, in most cases, a decision on timing of surgery. Retrospective studies showed that cardiac catheterizations in 45 of 111 consecutively investigated patients were superfluous. Thus, in 40% of these patients noninvasive methods were sufficient for a reliable decision on whether to proceed with surgery or conservative measures and for a satisfactory objective assessment of preoperative haemodynamics and morphology. Invasive methods should only be used when there are insufficient or discrepant noninvasive findings or when accompanying coronary heart disease must be excluded.
