Transcatheter Bailout: An Important Option During Complex Aortic Surgery.
Ann Thorac Surg Short Rep

Division of Adult Cardiothoracic Surgery, Department of Surgery, University of California, San Francisco, San Francisco, California.
This report presents the case of a 66-year-old man with acute torrential aortic insufficiency after a Ross procedure 20 years earlier, a biologic aortic valve replacement 16 years earlier, and a transcatheter valve-in-valve 4 years earlier. He underwent third-time sternotomy, revealing that the pulmonary autograft was heavily calcified and frozen to the homograft. The previous transcatheter valve-in-valve was explanted.

Article Synopsis
- Heavily calcified coronary artery disease complicates percutaneous coronary intervention (PCI), requiring advanced techniques like cutting balloons (CB), which need standardization for better effectiveness.
- The study presents the RODIN-CUT technique, which involves sequential CB inflations guided by intravascular ultrasound (IVUS) to improve plaque modification and stent expansion in difficult cases.
- Results indicate that RODIN-CUT achieved high procedural success rates and minimal complications, suggesting it could be a simple and cost-effective method for treating calcified lesions, though larger studies are needed to confirm its validity.
Exploring proteins within the coccolith matrix.

Coccolithophores comprise a major component of the oceanic carbon cycle. These unicellular algae produce ornate structures made of calcium carbonate, termed coccoliths, representing ~ 50% of calcite production in the open ocean. The exact molecular mechanisms which direct and control coccolith formation are unknown.

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).
