The Path to Modern PCI: Utilizing State-Of-The-Art Tools and Techniques to Optimize Patient Outcomes

Watch Dr. Ziad A. Ali, Dr. Kathleen Kearney and Dr. Simon J. Walsh discuss with Dr. J. Aaron Grantham their complex PCI approaches while leveraging SYNTAX II, IVUS utilization in Calcific lesions, and a live case walkthrough discussed throughout. 

Additional details

The results from SYNTAX II prove that multivessel disease PCI patients can experience excellent, CABG-like outcomes out to five years. Despite case complexity, SYNTAX II, when compared to SYNTAX I PCI, shows statistically significant risk reduction in MACCE and ST due to the modern approaches such as –

  • Imaging is key to Calcium detection, assessment, plan optimal treatment modalities and optimal stent placement
  • Rotablation for the preparation of severely Calcified lesions is associated with a superior acute success rate compared to standard and modified balloons
  • The Latest Generation DES plays an important role in elevating PCI Outcomes

OPTIMUM: Early Outcomes from a Prospective Registry of PCI in Patients at Prohibitive Risk for CABG

TCT Late-Breaking Clinical Science Session I, In Collaboration with Circulation

The outcomes of the OPTIMUM trial were presented during the TCT Late-Breaker Clinical Science Session by David E. Kandzari. This trial evaluated the outcomes of complex PCI patients who have multivessel or left main coronary artery disease and are deemed ineligible for CABG surgery. This session provides details of the OPTIMUM trial design and results of the study, including a panel discussion with commentary from Patrick W. Serruys, Jennifer Rymer, and David E. Kandzari. 

Additional details

The OPTIMUM prospective registry comparing short-term mortality rates to predicted mortality.

21 U.S. Sites, N=750

Primary Endpoint: 30-day/in-hospital mortality in PCI cohort compared with predicted STS surgical risk

Clinical Outcomes

OPTIMUM's meaningful results inform decision making and outcomes for a high-risk and largely unstudied patient population relative to risk/benefit, procedural strategies, and completeness of revascularization with complex PCI.

Most complex trial to-date, evaluating a largely unstudied population: 


Average Age


Diabetic patients


ACS patients


Patients with heart failure


Reporting no angina


Baseline SYNTAX Score


Severe calcification






Long lesions (> 20mm)

Following complex PCI, short-term mortality rates are similar to predicted mortality using surgical risk models and considerably lower than the evaluating surgeon’s estimates.

  • STS and EuroSCORE morality prediction models are intended to assess surgical mortality – these results are encouraging as they demonstrate similar PCI mortality rates


Surgical Risk Prediction30-day / In-hospital Mortality (N=726)
STS Predicted Mortality*5.3 ± 5.7
EuroSCORE II Predicted Mortality**5.7 ± 5.4
Surgeon’s Predicted Mortality10.4 ± 12.3
Observed 30-day / In-hospital Mortality5.6

6-month death: 12.3%

*STS Predicted Mortality score is a validated risk-prediction model for open surgery based on data from the STS National Adult Cardiac Surgery Database.
**EuroSCORE II Predicted Mortality score is a model used to estimate the in-hospital mortality after cardiac surgery provided by the European System for Cardiac Operative Risk Evaluation II. 

Chart showing Patient Reported Health Status

SAQ and KCCQ are both patient-reported health surveys assessing quality-of-life and angina frequency using a scale from 0-100, 1 being the lowest level of functioning

  • SAQ: Seattle Angina Questionnaire
  • KCCQ: Kansas City Cardiomyopathy Questionnaire

For patients which the heart team determined ineligible for coronary bypass surgery, PCI lowered residual Syntax Score from high to medium/low is 36% of patients.

Baseline & Residual SYNTAX Scores
Baseline (Pre-PCI)32.4
Residual (Post-PCI)15.0

*The average baseline SYNTAX score in clinical trials is 24 – this is a very complex patient subset.
