Based on the clinical findings, this is a classic presentation. Let me analyze it systematically.
Diagnosis: Rheumatic Heart Disease (RHD) with Combined Mitral Regurgitation + Aortic Stenosis
(Most likely: Chronic Rheumatic Valvular Heart Disease — Mixed Mitral and Aortic Valve Disease)
Clinical Feature Analysis
| Finding | Significance |
|---|---|
| Age 29, symptoms for 6 years (onset ~23 yr) | Suggests rheumatic etiology — sequela of childhood/adolescent rheumatic fever |
| Dyspnoea → PND/orthopnoea (3 yr) | Progressive left heart failure / pulmonary venous hypertension |
| Palpitations | Likely AF or LV volume overload |
| BP 100/70 mmHg | Low-normal BP — reduced cardiac output |
| Elevated JVP | Right heart failure / pulmonary hypertension |
| Pansystolic murmur at mitral area | Mitral Regurgitation (MR) |
| Ejection systolic murmur at aortic area | Aortic Stenosis (AS) |
| Apex displaced to 6th ICS | Cardiomegaly — LV dilatation (volume overload from MR) |
| Left parasternal heave | Right ventricular hypertrophy — secondary pulmonary hypertension |
Primary Diagnosis
Chronic Rheumatic Heart Disease with:
- Mitral Regurgitation (MR) — pansystolic murmur at apex, displaced apex (LV dilatation)
- Aortic Stenosis (AS) — ejection systolic murmur at aortic area (rheumatic AS invariably involves the mitral valve too, per Braunwald's: "In virtually every case [of rheumatic AS], the mitral valve is also involved")
- Pulmonary Hypertension — elevated JVP + left parasternal (RV) heave
- Biventricular failure — elevated JVP (right-sided), PND/orthopnoea (left-sided)
Pathophysiology
Rheumatic fever → mitral & aortic valve scarring/fibrosis
↓
MR (volume overload) → LV dilation → displaced apex (6th ICS)
AS (pressure overload) → LV hypertrophy → ejection murmur
↓
↑ Left atrial pressure → pulmonary venous hypertension
↓
Reactive pulmonary arterial hypertension
↓
RV hypertrophy/failure → parasternal heave + ↑ JVP
Key Points from Braunwald's Heart Disease
"AS is often accompanied by MR caused by rheumatic disease... The increased LV pressure secondary to LV outflow obstruction may augment the volume of MR flow... The result is a reduced forward cardiac output and marked left atrial and pulmonary venous hypertension." — Braunwald's Heart Disease, Chapter on Combined Valvular Lesions
"Rheumatic valve disease remains an important issue in many developing countries. In virtually every case, the mitral valve is also involved in the disease process." — Goldman-Cecil Medicine
Differential Diagnosis to Consider
| Condition | Against it |
|---|---|
| Infective endocarditis | Chronic 6-year history, no fever mentioned |
| Dilated cardiomyopathy | Functional MR alone wouldn't explain aortic ejection murmur |
| Congenital valvular disease | Onset in young adult after likely strep episode more typical of RHD |
Investigations to Confirm
- Echocardiography (TTE/TEE) — gold standard: morphology of valves (thickening, calcification, restricted leaflets), severity of MR and AS, LV dimensions, pulmonary artery pressure
- Chest X-ray — cardiomegaly, pulmonary congestion, mitral valve calcification
- ECG — LVH, P-mitrale, atrial fibrillation
- Anti-streptolysin O (ASO) titre — evidence of prior streptococcal infection
- Throat culture / CRP — active rheumatic activity
Bottom line: This 29-year-old has rheumatic mixed valvular heart disease — mitral regurgitation + aortic stenosis — with secondary pulmonary hypertension and biventricular decompensation. The young age, combined valve lesions, and the classic constellation of signs (pansystolic MR murmur + ejection AS murmur + parasternal heave + displaced apex) all point to chronic rheumatic etiology.
