Right ventricular and pulmonary vascular function indices for risk stratification of patients with pulmonary regurgitation.

Congenit Heart Dis 2019 Apr 8. Epub 2019 Apr 8.

Department of Cardiovascular Medicine, Mayo Clinic Rochester, Rochester, Minnesota.

Background: We hypothesized that echocardiographic indices of right ventricular to pulmonary artery (RV-PA) coupling were comparable to cardiac magnetic resonance imaging (CMRI)-derived RV volumetric indices in predicting disease severity in chronic pulmonary regurgitation (PR).

Methods: Patients with ≥ moderate PR (2003-2015) with and without prior CMRI scans were enrolled into the study cohort and validation cohort, respectively. Endpoint was to determine the association between noninvasive RV-PA coupling indices (tricuspid annular plane systolic excursion/right ventricular systolic pressure [TAPSE/RVSP] and fractional area change [FAC]/RVSP ratio) and markers of disease severity, and compared this association to that of CMRI-derived RV volumetric indices and markers of disease severity (peak oxygen consumption [VO ], NT-proBNP and atrial and/or ventricular arrhythmias).

Mitral valve stenosis after transcatheter aortic valve replacement: Case report and review of the literature.

Cardiovasc Revasc Med 2019 Mar 1. Epub 2019 Mar 1.

Interventional Cardiology Unit, Cardio Center, Humanitas Research Hospital, Rozzano-Milano, Italy.

Mitral stenosis is a rare and potentially severe complication of transcatheter aortic valve replacement (TAVR). Given the anatomic coupling and interdependence of the aortic and mitral valves, it comes by itself that procedures (either surgical or percutaneous) involving the aortic valve imply the risk of altering mitral valve function. Indeed, transcatheter aortic prostheses may impair adequate anterior mitral leaflet (AML) opening, especially when implanted in a "low" position, thus resulting in high transvalvular gradients.

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

Effect of Aortic Valve Calcium Quantity on Outcome After Balloon Aortic Valvuloplasty for Severe Aortic Stenosis.

Am J Cardiol 2018 Sep 4;122(6):1036-1041. Epub 2018 Aug 4.

Department of Cardiology, Royal Brompton and Harefield NHS Foundation Trust, Harefield Hospital, Middlesex, United Kingdom.

Balloon aortic valvuloplasty has a role in a select group of patients with severe aortic stenosis. Identifying those appropriate patients who will benefit most is key. Given previous evidence demonstrating that histologically the intervention involves a physical disrupting of the cusp's calcium we hypothesized that the quantity of calcium seen at CT will influence outcome.

Value of low-dose dobutamine stress echocardiography on defining true severe low gradient aortic stenosis in patients with preserved left ventricular ejection fraction.

Int J Cardiovasc Imaging 2018 Dec 23;34(12):1877-1887. Epub 2018 Jul 23.

Department of Internal Medicine I, University Hospital Würzburg, Würzburg, Germany.

Low-dose dobutamine stress echocardiography (DSE) is a valuable tool to distinguish true-severe (TS) from pseudo-severe (PS) low gradient aortic valve stenosis (LGAS) in patients with reduced left ventricular ejection fraction (LVEF). However, only scanty studies reported the clinical utility of DSE in differentiating TS-LGAS patients with preserved LVEF. We investigated the clinical utility of DSE in LGAS patients with preserved LVEF and the echocardiographic determinants suggestive of TS-LGAS. Read More

Very late presentation of anomalous origin of the left coronary artery from the pulmonary artery: case report.

J Cardiothorac Surg 2018 Jun 18;13(1):70. Epub 2018 Jun 18.

Division of Cardiovascular Medicine, Department of Medicine, Faculty of Medicine, Chulalongkorn University, Cardiac Center, King Chulalongkorn Memorial Hospital, Bangkok, 10330, Thailand.

Background: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle. Read More
