Clinical Information

Patient initials or Identifier Number

N. A.

Relevant Clinical History and Physical Exam

Female patient aged 65 years old known to be diabetic, hypertensive, recently diagnosed cardiac with history of ischemic heart disease 2 months ago, admitted once to CCU with unstable angina. Patient admitted to our Centre for elective coronary angiography. Her ECG shows sinus rhythm with ST segment depression in anterior leads. Her Echocardiography showed ischemic heart disease with good systolic function with regional segment wall motion abnormalities.

Relevant Test Results Prior to Catheterization


Relevant Catheterization Findings

LM: Atherosclerotic  vessel with ostial, body and distal significant stenosisLAD: Atherosclerotic vessel with ostial calcific subtotal lesion followed by midsegment long significant lesionLCX: Atherosclerotic vessel with ostial 60% lesionRCA: Atherosclerotic vessel without significant lesionRAMUS; Big atherosclerotic vessel without significant lesion

Interventional Management

Procedural Step

Engagement of LM with XB 3.5 Guiding catheter, then wiring of LAD, RAMUS, LCX with 3 PT2 MS guide wires pre-dilatation of LM-LAD lesion with semi-complaint balloon, then pre-dilatation of ostial LM lesion with the same balloon, Stenting of mid-segment LAD lesion with DES then stenting of ostial LM-LAD with another overlapping DES, then flaring of ostial LM stent was done by NC balloon  followed by POT, then compromisation of ostial LCX was noticed so re-wiring was done and strut opening, re-wiring of RAMUS and strut opening ( Notice 2 guiding catheter in same coronary >> ping-pong technique ), Kissing of LCX-RAMUS and Kissing of LAD-RAMUS was done then Trissing of three vessels together then Final POT with 4.5 NC balloon

Case Summary

Keep your eyes always on pressure during diagnostic procedure as you may miss ostial lesions.Even if you have no facilities, you can manage with the least possible available materials if you just calm down and think.Even if it looks impossible, you can do it.The technique of using two different catheters in the same coronary is called ping pong technique and can be used to manage complications during PCI as perforation or rotational atherectomy burr entrapment.
