TRANSRADIAL APPROACH: Manu Kaushik, MD ATHERECTOMY IN COMPLEX Bon Secours St Mary’s Hospital, PATIENTS Richmond, VA
DISCLOSURES No Relevant Financial Disclosures
CHALLENGES TO ACCEPTANCE OF TRA AS 1 ST LINE ▪ Patients with magnified Lack of operator comfort with advantages of TRA cPCI ▪ ACS/STEMI TRA avoided in complex patients ▪ Elderly Elderly ▪ CKD CKD patients with calcification ▪ Frail/Underweight Low EF Moderate/Severe valve disease
HOW TO ASSESS CALCIFICATION/NEED FOR ATHERECTOMY Pretest predictors predictors of calcification Age Previous failed PCI/Difficulty delivering stents Post CABG/radiation CKD Severe AS: Pre TAVR Intraprocedural predictors of calcification Calcification in other coronary segments Aorto ostial disease Angiography: Digital angiography - Train you eyes Gold standard for identification of calcification is intravascular imaging
TRA FOR ATHERECTOMY Attitudes and Concerns(Myths) “I can do it without atherectomy” Equipment not compatible Not enough guide support Bailout options not deliverable
CASE 1: 82 YEAR OLD, PRESENTS WITH CCS III ANGINA REFRACTORY TO MEDICAL THERAPY, EF 40-45%, PRIOR PARTIALLY SUCCESSFUL PTCA (INCOMPLETE BALLOON EXPANSION) TO MID RCA 3 YEARS AGO (STENT COULD NOT BE DELIVERED-TFA). INFERIOR-INFEROLATERAL ISCHEMIA
82 YEAR OLD, PRESENTS WITH CCS III ANGINA REFRACTORY TO MEDICAL THERAPY, EF 40-45%, PRIOR PARTIALLY SUCCESSFUL PTCA(INCOMPLETE BALLOON EXPANSION) TO MID RCA 3 YEARS AGO (STENT COULD NOT BE DELIVERED- TFA). INFERIOR-INFEROLATERAL ISCHEMIA Options Attempt as routine PCI ?? Lesion preparation Modified balloons: Scoring or cutting Atherectomy Rotational atherectomy or orbital atherectomy

82 YEAR OLD, PRESENTS WITH CCS III ANGINA REFRACTORY TO MEDICAL THERAPY, EF 40-45%, PRIOR PARTIALLY SUCCESSFUL PTCA (INCOMPLETE BALLOON EXPANSION) TO MID RCA 3 YEARS AGO (STENT COULD NOT BE DELIVERED-TFA), INFERIOR/INFEROLATERAL ISCHEMIA ▪ 6 Fr Slender Glidesheath Left radial ▪ 6 Fr AL 0.75 Guide ▪ 1.5 mm Rota burr; 4 passes at 170000 rpm for 15-25 seconds ▪ No pacemaker ▪ Mid RCA 3.0 stent dilated to 3.25 ▪ Prox RCA 4 stent dilated to 5.0
CASE 2: 94 YEAR OLD MALE WITH CCS III ANGINA, EF 30% (MULTIFACTORIAL), MODERATE TO SEVERE AS(AVA 1.1 CM2) ▪ Left system without significant disease ▪ Critical ostial disease with heavy calcification. Mid segment ectatic, with no significant distal disease ▪ Planned to perform PCI
94 YEAR OLD MAN WITH CCS III ANGINA, EF 30%(MULTIFACTORIAL), MODERATE TO SEVERE AS(AVA 1.1 CM2) ▪ Right Radial ▪ 7 Fr Terumo Glidesheath Slender ▪ 7 Fr JR4 Guide catheter for coaxial orientation ▪ Primary wiring by airmailing viper wire ▪ Diamondback orbital atherectomy with classic coronary crown ▪ 2 passes for 20 sec at low speed(80k); 1 pass at high speed(120k) for 15 sec
94 YEAR OLD MAN WITH CCS III ANGINA, EF 30%(MULTIFACTORIAL), MODERATE TO SEVERE AS(AVA 1.1 CM2)
94 YEAR OLD MAN WITH CCS III ANGINA, EF 30%(MULTIFACTORIAL), MODERATE TO SEVERE AS (AVA 1.1 CM2) ▪ OAC with 3 passes 1.25mm crown ▪ 4 mm by stent ▪ 5 mm NC balloon ▪ Final results
ORBITAL ATHERECTOMY VERSUS ROTATIONAL ATHERECTOMY
ORBITAL VERSUS ROTATIONAL ATHERECTOMY: MY PREFERENCE ▪ Orbital atherectomy ▪ Very large vessel(>3.5 mm) ▪ Coaxial device orientation ▪ Balloon/microcatheter uncrossable lesion: primary wiring with atherectomy wire ▪ Laser Atherectomy ▪ Under-expanded stent due to external calcium ▪ Rotational atherectomy ▪ Everything else

CASE 3: 68 YEAR OLD DIABETIC WITH ANTERIOR/APICAL ISCHEMIA WITH ANGINA, INTRAMYOCARDIAL LAD, EF 45%
CASE 3: 68 YEAR OLD DIABETIC WITH ANTERIOR/APICAL ISCHEMIA WITH ANGINA, INTRAMYOCARDIAL LAD, EF 45% ▪ True bifurcation disease, 1:1:1 ▪ Planned 2 stent strategy ▪ IVUS difficult to extend into diagonal ▪ Started with balloon dilatation of D1 ▪ Suboptimal dilatation of balloon ▪ Switched to Atherectomy strategy
CASE 3: 68 YEAR OLD DIABETIC WITH ANTERIOR/APICAL ISCHEMIA WITH ANGINA, INTRAMYOCARDIAL LAD, EF 45% ▪ 1.75 mm Burr in both LAD and D1 ▪ 2 passes each ▪ DK Crush, POT, SKB ▪ 4.5 prox LAD, 3.5 mm mid LAD, 3.25 D1 ▪ Final Results
SUMMARY ▪ Atherectomy makes it easy ▪ To deliver stent ▪ To ensure proper stent expansion(aorto-ostial lesions) ▪ To optimize for durable results(bifurcations/2 stent strategy) ▪ More helpful in radial procedures ▪ Radial approach for atherectomy ▪ Safe(r) than femoral approach ▪ No more difficult that femoral approach
