Table 1 Considerations for decompensation after transcatheter aortic valve replacement include cardiac pathology, drug-related adverse effects, valve dysfunction, and pulmonary disease with diagnostic considerations based on suspected cause.

From: Undiagnosed hypertrophic obstructive cardiomyopathy during transcatheter aortic valve replacement: a case report

Acute Hemodynamic Decompensation during TAVR
Differential Diagnostic and Treatment Considerations
MI, CHF exacerbation, cardiac arrest, arrythmia, cardiac tamponade, acute cordae rupture, aortic dissection, annular rupture Consider: 12-lead EKG, TTE, TEE
Anaphylaxis, vasodilating medications, inhaled anesthetics Verify medications & allergies, assess depth of anesthesia
Valve migraton, valve embolization, valve malfunction Consider: TEE, TTE, fluoroscopy
Pulmonary embolism, acute pulmonary edema, pneumothorax, hemothorax, hypoventilation, hypoxemia Consider: 12-lead EKG, TTE, TEE, auscultation, CXR
  1. CHF congestive heart failure, CXR chest X-ray, EKG electrocardiogram, MI myocardial infarction, TEE transesophageal echocardiography, TTE transthoracic echocardiography
