A 57-year-old man with personal history of dilated ischemic cardiomyopathy and advanced heart failure was referred to our unit for cardiac transplantation evaluation. After ruling out contraindications, elective cardiac transplantation was performed without postoperative complications. The patient was discharged from the intensive care unit to the general ward with severe volume overload, so intravenous furosemide was started. Central venous pressure assessment during orthostatism revealed a prominent v wave and abrupt y descent (Video 1). Two-dimensional echocardiography showed normal allograft function. Endomyocardial biopsy was performed by protocol and showed no evidence of cellular or humoral rejection. At the same time, right heart catheterization showed a prominent v wave and abrupt y descent in right atrial pressure (Figure 1, left, red arrows) and a rapid increase in right ventricular pressure during early diastole (Figure 1, right, red arrows), which confirmed the restrictive-constrictive physiology suspected from the physical examination.
A characteristic development of hemodynamics in heart and heart-lung transplants that mimics restrictive myocardial disease has been previously reported. Patients fulfill criteria for restrictive-constrictive physiology if they have increased diastolic pressure, an abrupt and rapid rise in pressure in early diastole, and rapid filling wave exceeding 4 mmHg. This hemodynamic pattern has been previously reported in patients with acute moderate cellular rejection. However, during the first weeks after heart transplantation, a restrictive-constrictive physiology may be present even in the absence of cellular rejection. This case shows that restrictive-constrictive physiology can be routinely assessed by physical examination.
