Undiagnosed hypertrophic obstructive cardiomyopathy during transcatheter aortic valve replacement: a case report.

J Med Case Rep 2018 Dec 18;12(1):372. Epub 2018 Dec 18.

Department of Anesthesiology, University of Florida College of Medicine, Gainesville, Florida, USA.

Background: Transcatheter aortic valve replacement is indicated for severe symptomatic aortic stenosis in patients who have a very high or prohibitive surgical risk as assessed pre-procedurally by the Society of Thoracic Surgery Risk Score, EuroSCORE (II), frailty testing, and other predictors. When combined with another left ventricular outflow tract obstruction, careful consideration must be taken prior to proceeding with transcatheter aortic valve replacement because an additional masked left ventricular outflow tract pathology can lead to challenging hemodynamics in the peri-deployment phase, as reported in this case.

Case Presentation: A 56-year-old Caucasian man with multiple comorbidities and severe aortic stenosis underwent transcatheter aortic valve replacement under monitored anesthesia care. Read More

Melody valve in mitral position: Complete fracture causing acute mitral stenosis in a child.

Catheter Cardiovasc Interv 2019 Feb 31;93(2):E101-E104. Epub 2018 Oct 31.

Division of Pediatric Cardiology, Mayo Clinic, Rochester, Minnesota.

We present a case of a 7-year-old boy with a history of multiple mitral valve interventions and subsequent Melody valve placement in the mitral position, who presented with acute mitral stenosis due to complete fracture of the Melody stent. He was born early with severe mitral and tricuspid insufficiency due to valvular dysplasia, and ended up with 4 sternotomies before the age of 2 due to mitral valve dysfunction and recurrent prosthetic valve thrombosis. He then developed mixed stenosis and regurgitation at age 6, and to avoid another sternotomy, valve-in-valve therapy with off-label use of a 20-mm Melody valve was done with hybrid procedure via trans-apical approach.

Totally Endoscopic Resection of Giant Left Atrial Myxoma Without Robotic Assistance.

Innovations (Phila) 2018 Mar/Apr;13(2):136-139

From the Department of Cardiovascular and Thoracic Surgery, Cardiovascular Center, E Hospital, Hanoi, Vietnam.

There was no report on the application of totally endoscopic surgery for giant atrial myxoma resection. A 62-year-old female patient with giant atrial myxoma causing severe mitral stenosis and acute pulmonary edema underwent a successful operation by totally endoscopic techniques without the assistance of robotic systems using four small trocar ports (three 5-mm trocars and one 12-mm trocar). The patient recovered uneventfully and was satisfied with cosmetic results. Read More

Severe heart failure (NYHA Class IV) is associated with increased left ventricular mass index and short mitral deceleration time in severe aortic valve stenosis.

Echocardiography 2018 08 20;35(8):1108-1115. Epub 2018 Apr 20.

Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Background: In aortic valve stenosis (AS), congestive heart failure (CHF) is a well-established symptom that indicates the need for surgical aortic valve replacement (SAVR). However, it is difficult to judge whether CHF symptoms such as dyspnea are caused by severe AS or other conditions, especially in elderly persons with restricted mobility or other organ complications. It is important to identify objective and noninvasive parameters associated with severe CHF symptoms in severe AS. Read More

Transcatheter Pulmonary Valve Replacement: Current State of Art.

Curr Cardiol Rep 2018 03 15;20(4):27. Epub 2018 Mar 15.

Sidra Cardiac Program, Sidra Medical & Research Center, Doha, Qatar.

Purpose Of Review: The past couple of decades have brought tremendous advances to the field of pediatric and adult congenital heart disease (CHD). Percutaneous valve interventions are now a cornerstone of not just the congenital cardiologist treating patients with congenital heart disease, but also-and numerically more importantly-for adult interventional cardiologists treating patients with acquired heart valve disease. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with right ventricular outflow tract (RVOT) dysfunction.
