Coronary artery disease and constrictive pericarditis cause diastolic dysfunction. Revascularization and nitroglycerin improved hemodynamics and diastolic function in a patient undergoing pericardiectomy.

Area of Science:

  • Cardiology
  • Cardiac Surgery

Background:

  • Coronary artery disease (CAD) and constrictive pericarditis (CP) can coexist, leading to diastolic dysfunction.
  • Diastolic dysfunction in this context often presents with a restrictive filling pattern and preserved systolic function.

Observation:

  • A case study involving a patient with pre-existing diastolic dysfunction due to CP and CAD.

Findings:

  • The patient underwent elective pericardiectomy and off-pump coronary artery bypass grafting.
  • Post-revascularization, administration of nitroglycerin significantly improved hemodynamic parameters.
  • A notable decrease in intra-chamber filling pressures indicated enhanced diastolic function.

Implications:

  • Revascularization plays a crucial role in managing diastolic dysfunction in patients with combined CAD and CP.
