Mr K
Relevant Clinical History and Physical Exam
56 year old Chinese male History Of Bilateral Hydronephrosis with Bilateral proximal Ureteric Calculus Bilateral NephrolithiasisPlan for J stenting procedure by Urology Team as part of pre operation optimization he was Referred to Cardiology team in view of ECG Changes ( attached ) Further history complain of reduce effort tolerance off recently o/e BP 145 mmHg/ 70 mmHg PR 89 bpm lungs clear cvs: no murmur no pedal edema

Interventional Management
Procedural Step
Procedural steps : 1) EBU 3.5 , 7 Fr 2) Wired using (fine cross with fielder XTR into distal LAD 3) Confirm in true lumen with selective contrast 4) Exchange with sion blue GW 5) Attempt D1 cto using fielder xtr with fine cross 6) Escalate to GIA 1ST cross then exchange with runthrough NS into distal D1 7) Predilate mLAD using sapphire 3 2.0 mm x 15 mm @10 atm (2.13) 8) Predilate d1 also using sapphire 3 ( 2.0 x15mm) 10 ( 2.13) 9) 1ST IVUS RUN LAD / D1 10) Scoreflex NS 2.5 x10( mLAD) 12 ( 2.50) – 24 ( 2.68) 11) Score flex NC2.5 x10 (D1) 12( 2.50) – 22( 2.65) 12) 2ND IVUS run post Scoreflex both vessel 13) DEB sequent please Neo 3.5 x 20 over D1 @6(3.5) 14) Stented mLAD with pramus premier 3.5 x 32 10 ( 3.43) 12 ( 3.58 ) 15) 3rd IVUS ( decide on optimization ) 16) Post dilate with Sapphire NC PTCA 3.5 x15 20atm ( 3.72 ) – 26 atm (3.89 ) 17) 4th IVUS 18) Post dilate with sapphire II NC PTCA 4.0 x10 16atm(4.14 ) – 20atm(4.41) 19) 5th IVUS LAD & D1 Good stent apposition Good result 20) Wire removed good result
