An Atypical Presentation of Right Atrial Flutter Following the Cox Maze Procedure and Left Atrial Reduction Surgery: A Case Report.

J Innov Card Rhythm Manag 2017 Jul 15;8(7):2790-2794. Epub 2017 Jul 15.

Brandon Regional Hospital, Riverview, FL.

The onset of recurrent atrial tachyarrhythmia (ATA) following the Cox maze procedure (CMP) is commonly encountered, and may be associated with increased perioperative mortality. The majority of recurrent ATA cases are localized to the left atrium following surgical ablation. Right atrial flutter (AFL) following the CMP is a less-frequent occurrence, and may pose a diagnostic challenge due to uncharacteristic surface electrocardiogram (ECG) and intracardiac activation patterns.

Endocarditis risk with bioprosthetic and mechanical valves: systematic review and meta-analysis.

Heart 2020 May 29. Epub 2020 May 29.

Division of Cardiovascular Diseases, Mayo Clinic College of Medicine, Rochester, Minnesota, USA.

Objective: Bioprosthetic valves are being used with increased frequency for valve replacement, with controversy regarding risk:benefit ratio compared with mechanical valves in younger patients. However, prior studies have been too small to provide comparative estimates of less common but serious adverse events such as infective endocarditis. We aimed to compare the incidence of infective endocarditis between bioprosthetic valves and mechanical valves. Read More

Preoperative Planning for Structural Heart Disease.

Radiol Clin North Am 2020 Jul 7;58(4):733-751. Epub 2020 May 7.

Russell H. Morgan Department of Radiology and Radiological Science, Johns Hopkins University School of Medicine, Johns Hopkins Hospital, 600 North Wolfe Street, Halsted B180, Baltimore, MD 21287, USA. Electronic address:

Preoperative assessment with computed tomography (CT) is critical before transcatheter interventions for structural heart disease. CT provides information for device selection, device sizing, and vascular access approach. The interpreting radiologist must have knowledge of appropriate CT protocols, how and where to obtain the important measurements, and know additional imaging characteristics that are important to describe for optimal support of the interventionalist.

Impact of COAPT trial exclusion criteria in real-world patients undergoing transcatheter mitral valve repair.

Int J Cardiol 2020 May 26. Epub 2020 May 26.

University of Cologne, Faculty of Medicine and University Hospital Cologne, Department III of Internal Medicine, Heart Center, Germany.

Background: The generalizability of the COAPT trial results on the benefit of TMVR in patients with secondary mitral regurgitation is unclear.

Methods: Functional and long-term clinical outcome were examined in 122 consecutive patients with secondary mitral regurgitation and reduced ejection fraction undergoing TMVR. "COAPT-like" patients were defined according to principal COAPT inclusion/exclusion criteria if all of the following was fulfilled: symptomatic mitral regurgitation grade 3+ or more according to American guidelines; left ventricular ejection fraction ≥20%, left ventricular end-systolic dimension ≤70 mm, estimated pulmonary artery systolic pressure ≤70 mmHg, mitral valve orifice area ≥4 cm, no prior mitral valve procedure, no right sided congestive heart failure, no COPD requiring home oxygen therapy and NYHA class less than IVb.

Clinical Impact of Preprocedural Moderate or Severe Mitral Regurgitation on Outcomes After Transcatheter Aortic Valve Replacement.

Can J Cardiol 2019 Dec 31. Epub 2019 Dec 31.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.

Background: The influence of improved mitral regurgitation (MR) on the outcomes of transcatheter aortic valve replacement (TAVR) is unknown. Our aim was to determine the impact of significant preprocedural MR and the improvement of MR after TAVR.

Methods: A population of 1587 patients from the Optimized Catheter Valvular Intervention Transcatheter Aortic Valve Implantation (OCEAN-TAVI) registry were evaluated. Read More

A sound knowledge of the functional anatomy of the mitral valve and the alterations caused by different diseases is indispensable for surgeons treating patients with mitral valve disease. Rheumatic mitral valve disease remains the most common heart valvular disorder in developing countries, whereas mitral regurgitation due myxomatous degeneration of the valve is the most common in developed countries. The mitral valve should be repaired whenever possible, as long as the outcome is predictably better than that of replacement. Read More

Left ventricular outflow tract pressure gradient changes after carvedilol-disopyramide cotherapy in a cat with hypertrophic obstructive cardiomyopathy.

J Vet Cardiol 2020 Apr 30;29:40-46. Epub 2020 Apr 30.

School of Veterinary Medicine, Rakuno Gakuen University, 582 Midori-machi, Bunkyodai, Ebetsu, Hokkaido 069-8501, Japan.

Disopyramide reduces the left ventricular outflow tract (LVOT) pressure gradient and improves symptoms in humans with hypertrophic obstructive cardiomyopathy (HOCM). However, the efficacy of disopyramide in cats has not been reported. We treated a cat with HOCM with carvedilol and disopyramide cotherapy and monitored the changes in LVOT flow velocity and N-terminal pro B-type natriuretic peptide (NT-proBNP) concentration.
