Progression of aortic stenosis after an acute myocardial infarction.

Open Heart 2022 Jun;9(1)

Québec Heart and Lung Institute, Laval University, Québec City, Québec, Canada

Background: Myocardial infarction (MI) has been shown to induce fibrotic remodelling of the mitral and tricuspid valves. It is unknown whether MI also induces pathological remodelling of the aortic valve and alters aortic stenosis (AS) progression. We thus compared AS progression after an acute MI and in patients with/without history of MI, and assessed post-MI pathobiological changes within the aortic valve leaflets in a sheep model.

Left Ventricular Diastolic Function: Comparison of Slow Coronary Flow Phenomenon and Left Ventricular Hypertrophy in the Absence of Obstructive Coronary Disease.

Cureus 2022 May 6;14(5):e24789. Epub 2022 May 6.

Cardiology Department, University Hospital 'St Ivan Rilski', Sofia, BGR.

Background An interplay of myocardial structural abnormalities and coronary arterial dysfunction underlies the worsening left ventricular compliance. The conventionally used angina drugs have demonstrated a beneficial effect on both angina and coronary flow in cases with microvascular dysfunction and non-obstructive coronary disease. Despite that, vasoactive therapy only partially affects diastolic function in this patient population. Read More

Minimally invasive strategies to treat valvular heart disease have emerged over the past 2 decades. The use of transcatheter aortic valve replacement in the treatment of severe aortic stenosis, for example, has recently expanded from high- to low-risk patients and became an alternative treatment for those with prohibitive surgical risk. With the increase in transcatheter strategies, multimodality imaging, including echocardiography, CT, fluoroscopy, and cardiac MRI, are used. Read More

[Early Structural Valve Deterioration of Bioprosthetic Mitral Valve in a Dialysis Patient].

Kyobu Geka 2022 May;75(5):335-339

Department of Cardiovascular Surgery, Northern Okinawa Medical Center, Nago, Japan.

Choice of prosthetic valve during valve replacement in dialysis patients is still controversial. There is a known risk of early structural valve deterioration of bioprosthesis in dialysis patients, whereas mechanical prosthesis is associated with a higher risk of bleeding and thrombotic events. A 68-year-old dialysis-dependent woman, who had undergone bioprosthetic mitral valve replacement at the age of 66, was admitted to our hospital because of general malaise and hypotension during dialysis.

Paravalvular Leak.

Methodist Debakey Cardiovasc J 2022 1;18(1):7-9. Epub 2022 Apr 1.

Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, US.

Despite improvements and advancements in surgical technique, paravalvular leaks (PVL) continue to present a challenge when caring for patients with prosthetic valve disease. Paravalvular leaks result from dehiscence of the surgical ring from the mitral annulus. Some theories suggest that uneven distribution of collagen fibers in the mitral annulus leaves the posterior mitral annulus without a well-formed fibrous structure, which may predispose it to recurrent mechanical injury that leads to PVL.

Percutaneous balloon mitral valvuloplasty using veno-arterial loop and neuro-embolic protection for mitral stenosis with thrombus.

Catheter Cardiovasc Interv 2022 Jun 14;99(7):2113-2116. Epub 2022 Apr 14.

Department of Cardiology, Zhongshan Hospital, Shanghai Institute of Cardiovascular Disease, Fudan University, Shanghai, China.

Percutaneous balloon mitral valvuloplasty (PBMV) is not traditionally suitable for patients with mitral stenosis (MS) and left atrium (LA) thrombus. Moreover, PBMV cannot be performed in patients with LA thrombus not resolving after anti-coagulation treatment. Here we present a case of PBMV using a novel technique employing both a veno-arterial loop and neuro-embolic protection, in a patient with MS and LA thrombus resistant to warfarin therapy. Read More
