Modest dilation using rotational atherectomy and drug-coated balloon for native coronary proximal lesion with patent internal thoracic artery graft.
J Cardiol Cases
December 2024
Department of Cardiology, Kyoto Saiseikai Hospital, Nagaokakyo, Japan.
Unlabelled: Intervention to proximal lesions should be avoided in graft-protected native coronary arteries in general, because there might be a risk for bypass-graft failure. An 81-year-old man with coronary artery bypass grafting surgery due to 3-vessel disease 17 years previously complained of worsening angina. Coronary angiography (CAG) revealed a diseased saphenous vein graft (SVG) and a probable functional occlusion in the mid left anterior descending coronary artery (LAD) concomitant with calcified severe stenosis in the left main (LM)-proximal LAD, and patent right internal thoracic artery (RITA)-LAD graft.

J Endovasc Ther
October 2024
Department of Vascular Surgery, Tianjin Medical University General Hospital, Tianjin, China.
Objective: To evaluate the long-term outcomes of the provisional extension to induce complete attachment technique (PETTICOAT) for the treatment of acute and subacute complicated type B aortic dissection (TBAD).
Methods: We retrospectively collected and analyzed the clinical data of patients with acute and subacute TBAD who were treated using the PETTICOAT technique at our center between March 2014 and March 2023. The primary endpoint was all-cause mortality; secondary endpoints were a composite of complications, such as entry flow, stent-graft-induced new entry (SINE), and re-intervention.
Aortic root enlargement versus stentless valve implantation for avoidance of patient-prosthesis mismatch in patients with small aortic root: protocol for a systematic review.
BMJ Open
August 2024
Department of Cardiac Surgery, Laval University, Quebec, Quebec, Canada.
Introduction: Avoiding patient-prosthesis mismatch (PPM) in patients with small aortic annulus (SAA) during aortic valve replacement (AVR) is still a challenging surgical problem. Among surgical options available, aortic root enlargement (ARE) and stentless valve implantation (SVI) are the two most commonly used strategies. This systematic review will be conducted searching for superiority evidence based on comparative studies between these two options.

Am J Cardiol

Department of Research, Baylor Scott and White Research Institute Plano, Texas; Research Department, The Heart Hospital Baylor, Plano, Texas.
Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been associated with favorable outcomes in patients with degenerated stentless bioprosthesis. However, whether the outcomes after ViV TAVR for failed stentless bioprosthesis differ between balloon-expandable valves (BEVs) and self-expanding valves (SEVs) remains unknown. Therefore, we retrospectively analyzed 59 consecutive patients who underwent ViV TAVR for failed stentless bioprsothesis with BEVs (n = 42) versus SEVs (n = 17) in a single-health care system between 2013 and 2022.

Interdiscip Cardiovasc Thorac Surg
May 2024
Department of Cardiac Surgery, University Hospitals Leuven, Leuven, Belgium.
Objectives: Patients with failed stentless aortic prostheses are a challenging population to treat, as reoperative procedures may be complex and catheter-based treatments are associated with a high rate of procedural events. Reoperative surgery using sutureless valves may be an alternative.
Methods: In this multicentre experience, we assess outcomes of 17 patients who underwent reoperative surgery using the Perceval valve (Corcym UK Limited, London, UK) inside Freestyle prosthesis (Medtronic Inc.
