A 61-year-old woman with a history of orthotopic heart transplantation for familial hypertrophic cardiomyopathy 20 years previously was admitted to the hospital with subacute, progressive, exertional dyspnoea. Quantitative assessment of the jugular venous pulse demonstrated a jugular venous pressure (JVP) of 16 cm H2O, while qualitative assessment revealed a paradoxical rise in JVP with inspiration, along with sharp and deep x and y descents (figure 1 and video 1).

Transthoracic echocardiography showed normal left and right ventricular function. MRI of the heart showed pericardial thickening and enhancement, diastolic bounce of the interventricular septum, and respirophasic septal shift with ventricular interdependence. Right heart catheterisation demonstrated sharp and deep x and y descents of the right atrial pressure tracing (figure 2). The constellation of clinical, imaging and invasive haemodynamic findings was consistent with constrictive pericarditis, a rare sequela of heart transplantation.1 Sternotomy confirmed the presence of a dense pericardium encasing the allograft. Following radical pericardiectomy and repeat orthotopic heart transplantation, the patient’s symptoms resolved, and she has returned to her usual active lifestyle.

Under normal conditions, decreased intrathoracic pressure during inspiration augments venous return to the right side of the heart, which is easily accommodated by a compliant right ventricle, leading to a decrease in JVP. The paradoxical rise in JVP with inspiration, known as Kussmaul’s sign, occurs in the setting of impaired right ventricular filling from any cause, including constrictive pericarditis.2

The components of the jugular venous waveform that are clinically observable at the bedside include the a wave, x descent, v wave and y descent. Under normal conditions, the x descent is more prominent than the y descent. In constrictive pericarditis, the unyielding pericardium causes elevated atrial pressure and limits ventricular filling to the early diastolic period. The resultant brisk and enhanced early diastolic filling produces a sharp and deep y descent, known as Friedreich’s sign.3 In the absence of atrial fibrillation, the prominent y descent often occurs in combination with a prominent x descent, creating two steep troughs known as the ‘W’ sign. This finding may be helpful in distinguishing constrictive pericarditis from restrictive cardiomyopathy, in which the x descent is typically diminished.4 5

Learning points

  • The paradoxical rise in jugular venous pressure (JVP) with inspiration, known as Kussmaul’s sign, and a sharp and deep y descent of the jugular venous waveform, known as Friedreich’s sign, are nonspecific physical findings of constrictive pericarditis.

  • The combination of sharp and steep x and y descents of the jugular venous waveform, known as the ‘W’ sign, is a physical finding of constrictive pericarditis and can be helpful in differentiating constrictive pericarditis from restrictive cardiomyopathy.

  • Chronic constrictive pericarditis is a rare complication of orthotopic heart transplantation. Pericardiectomy is the mainstay of treatment and typically leads to rapid symptomatic improvement. In early cases, or when surgery is contraindicated, diuretic medications may be used to improve symptoms.

  • In heart transplant recipients who develop right-sided heart failure, constrictive pericarditis should be included in the differential diagnosis, along with more common causes, such as rejection of the allograft, restrictive cardiomyopathy and cardiac allograft vasculopathy.
