Clinical Information

Patient initials or Identifier Number

Madam S

Relevant Clinical History and Physical Exam

A 70-year-old lady, non-smoker with background history of diabetes  mellitus, hypertension and 
end stage renal disease on regular haemodialysis presented with multiple admissions of unstable angina and NSTEMI.
Patient developed hypotension due to poor tolerability with haemodialysis. 
Her BP was 110/62 mmHg and pulse rate was 65/min.
Respiratory examination revealed equal breath sound bilaterally.

Relevant Test Results Prior to Catheterization

Blood investigations showed Hb of 11.1g/dl, creatinine 512 µmol/L,Troponin T 826.Echocardiography examination revealed reduced left ventricular function with ejection fraction of 45%, dilated left atrial, global hypokinetic and there was no clot or thrombus observed. There was also no pericardial effusion observed.ECG showed LVH pattern and T wave inversion V2 to V6.Chest X ray showed cardiomegaly.

Relevant Catheterization Findings

Coronary angiography showed normal LMT , 70% to 80% stenosis at proximal LAD, normal Lcx and RCA.we proceeded with PCI to LAD


Interventional Management

Procedural Step

The right radial artery (RRA) was punctured. 
A 6Fr EBU 3.0 was used to engage LMT with good support. 
A sion blue wire was inserted into LAD
The proximal LAD was predilated by NC 2.5x12mm balloon.
We noted a stained at around proximal LAD. Thus we decided to proceed with IVUS.
IVUS showed intramural haematoma and artherosclerotic plaque at proximal LAD. 
LAD lesions was treated with Synergy megatron (4.0x28mm) up to 14 atm.

Postdilated LAD with 4.0x15mm NC balloon at 18 atm.

IVUS was performed again.
Decided postdilate further with 4.5x15mm NC balloon at 14 atm.

Repeated IVUS and showed good result. 

Patient undergo heamodialysis well and her functional status improved remarkably after revascularization.

Case Summary

Following postdilatation with a NC balloon, there was residual contrast staining on angiography.  With help of IVUS, it revealed an intramural hematoma.We decided to stent over the hematoma with proper stent¡¯s size with help of IVUS.Final IVUS revealed that the stent was well opposed and the intramural hematoma was covered with no evidence of progression.Eccentric lesions, which compromise approximately 70% of coronary lesions are more likely to develop intramural hematomas.Intramural hematomas can occur even in a simple lesion during PCI. IVUS should be considered the gold standard in the diagnosis of intramural hematoma
