Iatrogenic coronary ostial stenosis after aortic valve replacement is a rare, life-threatening complication, which may follow implantation of either a mechanical or a biological prosthesis. Historically, this condition has been treated by urgent coronary bypass surgery but is associated with high morbidity and mortality, due to the hazards of early repeat sternotomy. We report a case of iatrogenic coronary ostial stenosis successfully treated with stenting and discuss the advantages of percutaneous intervention over coronary bypass surgery.

Aortic valve repair with sinus plication for a regurgitant bicuspid aortic valve: a case report.

Background: Repair of the regurgitant bicuspid aortic valve is an attractive alternative to valve replacement. Although good long-term outcomes have been reported, postoperative aortic stenosis remains a major late cause of repair failure in bicuspid aortic valves. Sinus plication is effective for creating a more symmetrical commissural angle, leading to a decrease in the mean transvalvular pressure gradient.

Aims: To evaluate the association between transcatheter edge-to-edge repair (TEER) and outcomes in patients with significant mitral regurgitation (MR) following acute myocardial infarction (MI), focusing on the aetiology of acute post-MI MR in high-risk surgical patients.
Methods And Results: The International Registry of MitraClip in Acute Mitral Regurgitation following Acute Myocardial Infarction (IREMMI) includes 187 patients with severe MR post-MI managed with TEER. Of these, 176 were included in the analysis, 23 (13%) patients had acute papillary muscle rupture (PMR) and 153 (87%) acute secondary MR.
Transcatheter closure of paravalvular leakage through multiple approaches after surgical mechanical valve replacements: A retrospective study.

November 2024
Department of Cardiovascular Surgery, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi Province, China.
Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
Warfarin-induced gastrointestinal bleeding with acute liver failure: A case report.
Medicine (Baltimore)
November 2024
Department of Pharmacy, The People's Hospital of Hezhou, Hezhou, China.
Rationale: Warfarin is the most commonly used drug in patients with mechanical valve replacement. Acute liver damage after warfarin is rare but potentially harmful. We present a case of warfarin-induced gastrointestinal bleeding with liver injury, pharmacy monitoring, and its therapy.

Aortic valve replacements, both surgical and transcatheter, are nowadays widely employed treatments. Although clinically effective, these procedures are correlated with potentially severe clinical complications which can be associated with the non-physiological haemodynamics that they establish. In this work, the fluid dynamics changes produced by surgical and transcatheter aortic valve replacements are analysed and compared with an ideal healthy native valve configuration, employing advanced fluid-structure interaction (FSI) simulations.
