Simone Biscaglia, Barry Uretsky, Emanuele Barbato, Carlos Collet, Yoshinobu Onuma, Allen Jeremias, Matteo Tebaldi, Abdul Hakeem, Norihiro Kogame, Jeroen Sonck, Javier Escaned, Patrick W. Serruys, Gregg W. Stone, and Gianluca Campo

Abstract Intracoronary physiology is routinely used in setting the indication for percutaneous coronary intervention (PCI) but seldom in assessing procedural results. This attitude is increasingly challenged by accumulated evidence demonstrating the value of post-PCI functional assessment in predicting long-term patient outcomes. Besides fractional flow reserve, a number of new indexes recently incorporated to clinical practice, including nonhyperemic pressure and functional angiographic indexes, provide new opportunities for the physiological assessment of PCI results. Largely, the benefit of these tools is derived from longitudinal analysis of the treated vessel, which allows precise identification of the vessel segment accounting for a suboptimal functional result and enabling operators to perform accurate PCI optimization. In this document the authors review available evidence supporting why physiological assessment should be extended to immediate post-PCI with the aim of improving patient outcomes. A step-by-step guide on how available physiological tools can be used for such purpose is provided.

Calcific Plaque Modification by Acoustic Shock Waves

Keyvan Karimi Galougahi, Sanjay Patel, Richard A. Shlofmitz, Akiko Maehara, Dean J. Kereiakes, Jonathan M. Hill, Gregg W. Stone and Ziad A. Ali

Abstract Constituting a significant proportion of lesions treated with transcatheter interventions in the coronary arteries, moderate-to-severe calcification portends lower procedural success rates, increased periprocedural major adverse events, and unfavorable long-term clinical outcomes compared with noncalcific plaques. Adapted from the lithotripsy technology for treatment of nephrolithiasis, intravascular lithotripsy is a new technique for treatment of severely calcific lesions that uses acoustic shock waves in a balloon-based system to induce fracture in the calcium deposits to facilitate luminal gain and stent expansion. Herein, we summarize the physics and characteristics of the currently available intravascular lithotripsy system (Shockwave Medical, Santa Clara, CA), the clinical data on intravascular lithotripsy use in the coronary arteries, and future directions for adoption of the technique in percutaneous coronary intervention.

Sex Differences in Ischemic and Bleeding Outcomes in Patients With Non–ST-Segment–Elevation Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention

Jean-Guillaume Dillinger, Gregory Ducrocq, Yedid Elbez, Marc Cohen, Christoph Bode, Charles Pollack Jr, Birute Petrauskiene, Patrick Henry, Maria Dorobantu, William J. French, Stephen D. Wiviott, Marc S. Sabatine, Shamir R. Mehta and Philippe Gabriel Steg

Background: Previous studies have observed poorer outcomes in females with myocardial infarction, but older age and lower use of percutaneous coronary intervention in females are factors that potentially explain the worse outcome. This study sought to determine if female sex is an independent factor of ischemic and bleeding outcomes in non–ST-segment–elevation acute coronary syndrome treated with a systematic invasive approach.

Use of a Novel Septal Occluder Device for Left Atrial Appendage Closure in Patients With Postsurgical and Postlariat Leaks or Anatomies Unsuitable for Conventional Percutaneous Occlusion

Domenico G. Della Rocca, Rodney P. Horton, Nicola Tarantino, Christoffel Johannes Van Niekerk, Chintan Trivedi, Qiong Chen, Sanghamitra Mohanty, Alisara Anannab, Ghulam Murtaza, Krishna Akella, Carola Gianni, Mohamed Bassiouny, Ashkan Ahmadian-Tehrani, Amin Al-Ahmad, J. David Burkhardt, Veronica N. Natale, Matthew Price, G. Joseph Gallinghouse, Douglas N. Gibson, Dhanunjaya Lakkireddy, Luigi Di Biase and Andrea Natale

Background: Interventional therapies aiming at excluding the left atrial appendage (LAA) from systemic circulation have been established as a valid alternative to oral anticoagulation in patients at high thromboembolic risk. However, their efficacy on stroke prophylaxis may be compromised owing to incomplete LAA closure. Additionally, the need for an alternative thromboembolic prevention may remain unmet in patients with contraindications to oral anticoagulation whose appendage anatomy is unsuitable for some conventional devices commercially available. We aimed at evaluating the feasibility of LAA closure with the novel Gore Cardioform Septal Occluder in patients with incomplete appendage ligation or anatomic features which do not meet the manufacturer’s requirements for Watchman deployment.
