Day 29-
• Ultrasound examination of the liver:– Veins of the liver are dilated. Lower edge of the liver is
round. Minimal ascites. No sign of portal vein thrombosis. – Diameter of inferior vena cava is increased with reduced
variation of the size with respiratory cycles– Findings as in right heart failure. – Cholelithiasis and signs of chronic cholecystitis
• New echocardiography– Normal RV and LV function. No wall hypertrophy. No
valvular lesion. Normal movement of the septum, normal flow pattern and flow velocities that tells against constrictive pericarditis.
Day 31Patient deteriorates acutely
• Creatinine increased from 84 to 192 umol/L– Enalapril stopped
• Growth of a streptococus in the culture of ascites fluid– Leucocytes in the ascites fluid 0.6 x 109/L– No fever, no abdominal pain– Spontaneous bacterial peritonitis– Treatment with Piperacillin /Tazobactum
• Deterioration of general condition– Systolic BP 85 mmHg, little urine production– Acute renal failure due to peritonitis, iodinated contrasts, ACE inhibitor– Creatinine increased from 84 to 307 umol/L, P-Potassium 5.5 mmol /L
• Patient transferred to the intermediate care unit– Treated with infusion of electrolytes, albumin, noradrenaline– After three days: good urine production. Discharged from the intermediate
care unit
Day 33-
• Cytology of pleural fluid
– No malignant cells
– Many inflammatory cells, mostly lymphocytes
• Cytology of ascites fluid
– No malignant cells
– Many inflammatory cells, mostly lymphocytes
• Abdominal fat biopsy
– No sign of amyloidosis
Day 43-
• Continued treatment with spironolactone. Successive weight loss
• Garstroscopy
– Petechial changes in the fundus as in NSAID use
– Suspect pyloric stenosis
– Treatment with PPI started
Day 43-?Lymphoma
• Malignant lymphoma is unlikely
– No palpable lymph nodes
– No fever or sweating
– Normal LD
• Consultation with thoracic surgeon
– The lymph nodes in the mediastinum are not unusual in size or number. No need of mediastinoscopy
Day 43-Why not constrictive pericarditis?
• Second opinion / re-evaluation of the echocardiography pictures
– Poor quality of recording
– No obvious signs of constrictive pericarditis
– No abnormal septum movement
– No ventricular-interdependence
– In all examinations, there is increased diameter of inferior vena cava without variation of the size during respiratory cycle
Day 43-Why not constrictive pericarditis?
• Cardiac CT scan
– Relatively little, tubular LV. LV-EF 60%.
– Atypical movement of septum during heart cycle. ?Increased pressure in the pulmonary circulation.
– Increased size of the right ventricle, right atrium
– No calcification of the pericardium. No obvious thickening of the pericardium.
– No significant stenosis of the coronary arteries.
– No typical finding as in constrictive pericarditis.
“If the map does not agree with the ground, the map is wrong”
Gordon Livingstone, M.D. in “Too Soon Old, Too Late Smart”
Day 56-Why not constrictive pericarditis?
• Re-evaluation of the CT thorax, CT abdomen, and cardiac CT scan:– The size of the lymph nodes have not increased during
two months. Most are < 10 mm
– Slight thickening of pericardium. Pleural adehesionsand atelectasis
– Small diameter of LV, LA. Increased size of the RV is a visual illusion.
– Inferior vena cava is dilated
– Size of the cardiac chambers may suggest constrictive or restrictive pathology
Day 56-A diagnostic procedure was performed
Day 56-A diagnostic procedure was performed
• Right heart catheterization:
– Right ventricular curve has somewhat, although not typical, dip-plateau appearance
– Increased filling pressure on the right side.
– Simultaneous increase of RV and LV filling pressure by 10 mm Hg during uplift of the legs.
– There is probably also a component of restrictive heart disease since the LVEDP was 7-8 mm Hg more than the RVEDP
“Dip-plateau appearance” “Square root sign”
(Schematic fig only for illustrationNot from this patient)
Day 56-Why not constrictive pericarditis?
• New transthoracic echocardiography– Pericardium: somewhat increased echogenicity– No significant increase in the systolic pulmonary
arterial pressure– Pathological variation in the diastolic flow across AV
valves during respiration with variation > 25%.– Dilated inferior vena cava with reduced variation in
size during respiratory cycle suggesting increased pressure in the right atrium ( about 15 mm Hg)
– E/A 1.2, E/é 6– Some of these findings are suggestive of constrictive
pericarditis.
Day 56-Planned for elective pericardiectomy
• Rheumatology consultation– No obvious rheumatic-, systemic-disease or
vasculitis. Laboratory tests for IgG4 related diseases may be helpful. Let the pathologists examine for IgG4 positive plasma cells in the pericardial tissue.
• Myocardial biopsy– Staining for amyloid is negative. Non-specific
hypertrophy of cardiac myocytes. No sign of primary muscle disease. No IgG4 positive cells.
Day 67-
• Pericardiectomy
– Thick and inflamed pericardial fat. Thick pericardium that is non-elastic, and constrictive. Severe adhesions. Heart freed from pericardium, and most of the pericardium removed. CVP reduced from 26 to 12
Day 71-
• Patient deteriorates again– Increased breathlessness, respiratory rate 25/min,
peripheral capillary oxygen saturation 94% with 2 L oxygen /min
– Disoriented– Temperature 39.7 degree C, BP 120/70 mm Hg, pulse
130/min,
• Transferred to ICU • Sepsis
– Treated with piperacillin + gentamycin– Recovers over several days
Day 82-
• Discharged from the hospital• Follow up after one week
– Much better. Can walk 500 m at a stretch
• Histology of pericardium– “signs of mainly chronic, and also acute pericarditis. Severe
fibrosis. In some areas, there are granulocytes. Pericardial tissue shows exudates on both sides, and infiltration by many lymphocytes , and in some areas numerous plasma cells. No significant eosinophilia. Numerous cells (over 50 per HPF) positive for IgG4. Since there are numerous plasma cells, the percentage of IgG4 positive plasma cells is not especially high. Moderate probability of an IgG4 related disease.
Final diagnosis
IgG4-related constrictive pericarditis
Day 137
• Follow up at rheumatology out patient dept– Feels much stronger– Medicines: Furosemide 40 mg, Spironolactone 25 mg, metformin 1000
mg.– Pulse 80/min, BP 120/70 mmHg, some pitting edema at the ankles,
heart/lungs: normal findings– CRP 3 mg/L, SR 44 mm, Hb 123, electrolytes normal– S-IgG4 1.48 (1.25) g/L– C3 1.3 (0.67-1.29) g/L– S-anti-citrullinated protein antibody IgG <7– Anti-proteinase 3 antibody IgG [ANCA] 21 (<20) kE/L – Anti-myeloperoxidase antibody IgG [ANCA], not detected– Anti-nuclear antibody, not detected
– Patient put on prednisolone 7.5 mg /day
