• SURTAVI met its primary endpoint: TAVR with a self-expanding CoreValve or Evolut R bioprosthesis is noninferior to SAVR for all-cause mortality or disabling stroke at 24 months.

• TAVR had significantly less 30 day stroke, AKI, atrial fibrillation and transfusion use and a superior quality of life at 30 days.

• TAVR resulted in significantly improved AV hemodynamics with lower mean gradients and larger aortic valve areas than SAVR through 24 months.

• SAVR had less residual aortic regurgitation, major vascular complications and fewer new pacemakers.

• Need for a new pacemaker after TAVR was not associated with increased mortality.

Page 13: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Background

Risk of recurrent VTE is up to 10% in the first year if anticoagulation (AC) is

stopped in patients without reversible risk factors for VTE

ASA has been previously shown to reduced rates of recurrent VTE

Although extended AC prevents recurrent VTE, there is reluctance to extend

treatment beyond 6-12 months due to bleeding

Page 17: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Summary and Conclusions

In patients with VTE who completed 6 to 12 months of treatment, rivaroxaban

(20 or 10 mg once daily) is superior to ASA for recurrent VTE and are

associated with similar rates of bleeding

Compared with aspirin, NNT to prevent one VTE without increase in bleeding for

rivaroxaban 20 mg QD = 33 and rivaroxaban 10 mg QD = 30

Rivaroxaban 10 mg once daily provides an additional option for extended

VTE treatment

*Number needed to treat (NNT) compared with aspirin for primary efficacy outcome up to 1 year

Introduction

• ~50% of the STEMI patients have multivessel disease at

presentation (≥50% stenosis in ≥1 non-infarct-related

arteries (non-IRAs)

• Management of these non-IRAs lesions an unresolved

clinical dilemma

Conclusions

• In multivessel STEMI patients, FFR-guided complete

revascularization of non-IRA in the acute phase reduced

the risk of the composite MACCE outcome compared to

treatment of the IRA only

• This reduction was mainly driven by the decreased need

for subsequent revascularization

Page 24: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Background

• Benefits of successful CTO-PCI include reduced angina and

improvements in QOL, LVEF, or survival.

• CTO-PCI can lead to procedure-related complications.

• Evidence for CTO-PCI mostly from observational studies,

most of which compared successful and failed CTO-PCI

without a control group receiving optimal medical treatment.

DECISION CTO Trial

• OBJECTIVE: To compare the outcomes of OMT alone with

PCI coupled with OMT in patients with CTO.

• DESIGN: a prospective, open-label, randomized trial

• Inclusion Criteria:

- Silent ischemia, stable angina, or ACS

- De novo CTO located in a proximal to mid epicardial coronary artery with a

reference diameter of ≥2.5 mm

Page 26: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Study Procedures

• Patients who were assigned to PCIs underwent CTO-PCI using DES within 30

days after randomization

• In cases of failed CTO-PCI, additional attempts were allowed within 30 days

after the index procedure.

• Patients were prescribed guideline derived OMT including aspirin, P2Y12

receptor inhibitors (>12months in case of PCI), BB, CCB, nitrate, ACEi/ARB,

and statin.

• Blood pressure and diabetic control, smoking cessation, weight control, and

regular exercise were recommended.

Conclusion

• DECISION-CTO trial is the first RCT to compare the strategy of OMT alone with that of

PCI in patients with coronary CTO.

• The ITT analysis showed that OMT as an initial strategy was non-inferior to PCI with

respect to the primary endpoint of the composite of death, MI, stroke, or any

revascularization at 3 years.

• Quality of life in the OMT and the PCI groups were comparable.

• OMT could be a reasonable initial treatment strategy for coronary CTO compared

with CTO-PCI.

McMaster University

Page 31: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Background• >5 Million Americans >45 years old undergo in-patient noncardiac surgery/year

and 1.3% die in hospital

– Cardiac complications are leading cause

• Myocardial injury after noncardiac surgery (MINS) is

– Defined as myocardial injury caused by ischemia that occurs during or within 30 days after surgery and is independently associated with mortality

• Little is known about relationship between perioperative hsTnT measurements and 30-day mortality and MINS

Page 32: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Design and Methods • Prospective, international, cohort study

• >45 yrs underwent in-patient noncardiac surgery

• Participating countries (23 centers in 13 countries)

• Patients had hsTnT measurements 6-12 hours after surgery and daily for 3 days

– 40.4% had preoperative hsTnT measurement

Page 33: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Results• 21,842 participants

– Mean age 63 years, 49% were female

• Most common types of surgery

– Major orthopedic (16%)

– Major general (20%)

– Low-risk (35%)

• 21,050 (96.4%) completed 30-day follow-up

– 266 patients (1.2%; 95% CI, 1.1-1.4) died within 30 days of surgery

• Among 4385 patients with elevated postop hsTnT

– 481 (11.0%) had non-ischemic (e.g., sepsis) non-MINS hsTnT elevation

– 13.8% of patients with elevated perioperative hsTnT had their peak value before surgery

Page 36: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Conclusions• Elevated postoperative hsTnT measurements strongly associated with 30-

day mortality (regardless of eGFR and sex)

• 13.8% of patients had their peak value before surgery suggests

– Physicians should consider obtaining preoperative hsTnT measurement in patients who they plan to measure hsTnT after surgery

• MINS may explain 24% of perioperative deaths

• 93% of MINS would probably go undetected without troponin monitoring

Page 38: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

• Subclinical leaflet thrombosis (reduced leaflet motion on CT) reported in ~10-15% of

patients after TAVR and surgical bioprosthetic AV

– Less common in patients on therapeutic anticoagulation with warfarin and resolves with

initiation of warfarin.

• No data on differences between SAVR and TAVR, impact of NOACs on prevention,

treatment, and outcomes

• Objective: Characterize incidence of leaflet thrombosis in SAVR/TAVR and role of

NOACs in management

Conclusions

• In a heterogeneous cohort of bioprosthetic AV, reduced leaflet motion occurred 12% on CT.

• SAVR vs TAVR, had lower incidence of reduced leaflet motion (3.6% vs. 12%; p<0.04).

However, SAVR patients younger and fewer comorbidities.

• Anticoagulation with both warfarin and NOACs and not DAPT which is the standard of care

were effective in prevention and treatment of reduced leaflet motion.

• Cases of subclinical leaflet thrombosis diagnosed by CT are hemodynamically silent and hence

missed by TTE

• While the death, MI and stroke rates were not significantly different between the 2 groups,

subclinical leaflet thrombosis was associated with increased rates of TIAs and strokes/TIAs.

Background

• Management of stable coronary disease: optimize risk factors, OMT

– Revascularize those with resistant symptoms and proven ischemia

• FAME & DEFER showed FFR to invasive angiography has

prognostic benefits

• Combination of OMT + FFR-guided revascularization current best

invasive management strategy for patients with stable angina

Page 47: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Optimal Non-Invasive Strategy

• Non-invasive ischemia testing with perfusion imaging accurately

predicts flow-limiting stenosis and outcomes

• CMR perfusion imaging highest accuracy of non-invasive testing

– No radiation

– Gives anatomy, function, and myocardial structure

• Combination of OMT + CMR perfusion current best non-invasive

management strategy for patients with stable angina

Page 48: Rapid Fire Review of ACC.17 Late-Breaking Clinical Trials · Study Design Aim: Compare the efficacy and safety of once daily rivaroxaban (20 or 10 mg) with aspirin (100 mg) in VTE

Hypothesis

• In patients with stable angina and intermediate to high

risk of CAD, guiding the initial management with OMT

+ CMR-perfusion imaging is non-inferior to OMT +

invasive angiography with FFR

Optimal Medical Therpy

• All patients received OMT

– ASA or Clopidogrel

– Statin (goal LDL <2 mmol/L (77 mg/dL), total chol <4 mmol/L (154 mg/dL))

– ACE-I or ARB (goal BP <130/80)

– Counseling (goal BMI <25, random glucose <6 mmol/L (108 mg/dL), non-

smoking)

Conclusions

• CMR-perfusion guided management of stable angina is

noninferior for the MACE endpoint at 1 year compared with

invasive angiography and FFR

• First trial to show that CMR-perfusion imaging could guide

patient management in a high-risk population with the same

effectiveness as invasive angiography with FFR
