We present the first case series using Shockwave Intravascular Lithotripsy (S-IVL; Shockwave Medical), a novel coronary calcium modification device, in patients with heavily calcified unprotected left main (LM) coronary artery disease (CAD). Decisions regarding surgical vs percutaneous revascularization in LM-CAD patients are based on anatomical complexity and perceived surgical risk. In this series, we present the use of S-IVL in a patient with LM-CAD with multivessel disease who declined surgery, a patient with an isolated LM-CAD and severe cardiomyopathy, and a late nonagenarian patient where surgical revascularization was not an option.

Background: Treating heavily calcified vessels is a challenging task in patients with an impaired left ventricular ejection fraction. Percutaneous mechanical circulatory support (pMCS) is increasingly used in patients in high-risk percutaneous coronary intervention (HRPCI).
Methods: In this retrospective registry, we investigated 25 patients undergoing a protected HRPCI receiving either intravascular lithotripsy (IVL + pMCS; = 11) or rotational atherectomy (RA + pMCS; = 14).

The complexity of chronic total occlusion percutaneous coronary intervention (CTO PCI) involving calcification is high, and completing the procedure with an antegrade approach is often challenging. However, calcification is also a significant obstacle in the retrograde approach, where it has been reported as a predictor of CTO PCI failure even after successful channel crossing. Overcoming calcification in the retrograde approach is, therefore, crucial.

There is a growing trend of patients with significant comorbidities among those referred for percutaneous coronary intervention (PCI). Consequently, the number of patients undergoing complex high risk indicated PCI (CHIP) is rising. CHIP patients frequently present with factors predisposing to extensive drug-eluting stent (DES) implantation, such as bifurcation and/or heavily calcified coronary lesions, which exposes them to the risks associated with an increased stent burden.

In patients undergoing percutaneous coronary intervention (PCI), severely calcified lesions remain a great challenge even in the drug-eluting stent (DES) era. Intravascular lithotripsy (IVL) is effective for modification of severely calcified lesions prior to DES implantation. However, the efficacy of PCI with drug-coated balloon (DCB) following IVL has not been fully elucidated.

Here we use morphological and assemblage data sets within a size-trait model to investigate the mix of cellular biogeochemical traits (size, biomass, calcite) present in high latitude calcareous nannoplankton communities through the Oligocene (ca. 34-26 Ma) to better understand the biogeochemical consequences of past climate variability on this major calcifying phytoplankton group.
