The ongoing saga of the evolution of percutaneous coronary interventions: From balloon angioplasty to recent innovations to future prospects.

Can J Cardiol 2022 Jun 28. Epub 2022 Jun 28.

Interventional Cardiology, Department of Medicine, Montreal Heart Institute, Université de Montréal, Montréal, QC, Canada.

The advances in percutaneous coronary interventions (PCI) have been, above all, dependent on the work of pioneers in surgery, radiology and interventional cardiology. From Grüntzig's first balloon angioplasty, PCI has expanded through technology development, improved protocols, and dissemination of best-practice techniques. We can nowadays treat more complex lesions in higher-risk patients with favourable results. Read More

Predicting narrow ureters before ureteroscopic lithotripsy with a neural network: a retrospective bicenter study.

Urolithiasis 2022 Jun 23. Epub 2022 Jun 23.

Department of Urology, Shanghai General Hospital, School of Medicine, Shanghai Jiao Tong University, No. 100 Hai Nin Road, Shanghai, 200080, China.

In some patients, the passage of semi-rigid ureteroscopes up the ureter is impossible due to narrow ureteral lumen. We established a neural network to predict the inability of the ureter to accommodate the semi-rigid ureteroscope and the need for active or passive dilatation using non-contrast computed tomography (CT) images. Data were collected retrospectively from two centers of 1989 eligible patients who underwent ureteroscopic lithotripsy with ureteral stones. Read More
