A 42-vear old- patient Anil Kapoor suffers from tuberculosis. He has come to see his physician with complaints of yspnea, pains in the right upper quadrant, and subfebrile fever. The symptoms emerged four weeks ago and were progressing. On examination: the face is pale and rounded; orthopnea is evident; the area of the cardiac dullness is increased to the left and to the right by 2 cmheart rate is 100 per minute , BP IS 90/60 mmHa. On auscultation : muffled heart sounds , crackles at the base of lungs. Breathing rate is 26 per minute. The neck veins Are distended; the liver is tender on palpation and extends 3 cm below the costal margin ; there is trace pretibial and feet edema. An X-ray examination of the chest shows the globular shadow of the heart.1. Does the patient have signs of cardiac insufficiency ? Substantiate your answer. 33 TasÀ 2. What additional tests are required to specify the form of the heart pathology in this case?

1. Does he have cardiac insufficiency?
Yes. He has marked congestive cardiac failure, involving both systemic and pulmonary venous congestion. The presentation also strongly suggests a large pericardial effusion causing cardiac tamponade, most likely from tuberculous pericarditis.
Evidence of impaired cardiac output / tamponade
- Progressive dyspnea and orthopnea
- Tachycardia: 100/min
- Hypotension: 90/60 mmHg
- Muffled heart sounds
- Distended neck veins
- Enlarged cardiac silhouette with a globular or “water-bottle” heart on chest X-ray
- Cardiac dullness enlarged both rightward and leftward
This combination of hypotension, raised JVP, and muffled heart sounds is Beck's triad of cardiac tamponade.
Evidence of pulmonary venous congestion and left-sided failure
- Tachypnea: 26/min
- Basal lung crackles
- Orthopnea
Evidence of systemic venous congestion and right-sided failure
- Tender congested liver, 3 cm below the costal margin
- Pretibial and pedal edema
- Distended neck veins
- Right-upper-quadrant discomfort from hepatic congestion
Thus, this is not simply stable chronic heart failure. The subacute onset, tuberculosis history, globular cardiac shadow, raised JVP, hypotension, and muffled sounds indicate hemodynamically significant pericardial effusion with impending or established tamponade. In tamponade, accumulation of pericardial fluid restricts diastolic filling, reduces stroke volume and blood pressure, and produces systemic venous congestion. Harrison’s Principles of Internal Medicine, p. 2125.
This requires urgent hospital assessment, because tamponade can deteriorate rapidly and drainage should not be delayed if confirmed with hemodynamic compromise.
2. Tests to define the cardiac pathology
The goal is to confirm:
- Pericardial effusion and tamponade physiology
- Tuberculous cause
- Whether constrictive or effusive-constrictive pericarditis has developed
| Test | Purpose / expected findings |
|---|---|
| Urgent transthoracic echocardiography with Doppler | First-line test. Defines fluid volume and distribution; looks for right atrial systolic collapse, right ventricular diastolic collapse, dilated IVC with poor inspiratory collapse, and respiratory variation in mitral/tricuspid inflow. These support tamponade. |
| ECG | May show sinus tachycardia, low QRS voltage, and electrical alternans in a large effusion. May also show diffuse ST elevation and PR depression if active pericarditis is present. |
| Repeat chest X-ray | Supports large chronic effusion by a globular cardiac silhouette; also assesses pulmonary TB, pleural effusions, and pulmonary edema. It cannot by itself diagnose tamponade. |
| Pericardiocentesis under echocardiographic guidance | Both therapeutic and diagnostic if tamponade is present. Measure opening pericardial pressure and send fluid for analysis. |
| Pericardial-fluid testing | Cell count and differential, protein/LDH, glucose, Gram stain, bacterial culture, AFB smear and mycobacterial culture, nucleic-acid amplification/PCR for M. tuberculosis, ADA, interferon-gamma where available, and cytology to exclude malignancy. |
| Pericardial biopsy | If fluid testing is nondiagnostic but TB pericarditis remains likely. Histology may show caseating granulomas; tissue can be sent for AFB culture and PCR. |
| CBC, ESR/CRP, renal/liver function, electrolytes, troponin, BNP | Assesses inflammation, organ congestion/hypoperfusion, alternate myocardial involvement, and baseline status prior to treatment. |
| CT chest or cardiac MRI | Useful when echo is equivocal or loculated effusion, pericardial thickening, inflammation, calcification, mediastinal lymph nodes, or pulmonary TB need definition. |
| Right- and left-heart catheterization | Usually not needed initially. Consider if the diagnosis remains uncertain, especially to distinguish tamponade from constrictive pericarditis or restrictive cardiomyopathy. |
For suspected tuberculous pericarditis, pericardial-fluid ADA elevation, TB PCR, mycobacterial culture, and biopsy are particularly relevant. A pericardial-fluid culture can be positive in many cases, while PCR and biopsy help when routine testing is unrevealing. Goldman-Cecil Medicine, p. 723. The ESC pericarditis guidance likewise includes echocardiography and multimodality imaging in the diagnostic work-up.
Most likely working diagnosis:
Tuberculous exudative pericarditis with large pericardial effusion, causing cardiac tamponade and biventricular congestive cardiac failure.
Tuberculous exudative pericarditis with large pericardial effusion, causing cardiac tamponade and biventricular congestive cardiac failure.
