Left ventricular outflow tract (LVOT) obstruction is a recognized complication of transcatheter mitral valve-in-valve replacement in previous surgical prostheses. We describe a patient who was high risk for repeat open surgery in whom the LVOT was compromised by a surgical strut and the potential for LVOT obstruction. A novel approach to avoiding this complication was utilized. A perfusion balloon was inflated in the outflow tract to provide an opposing force during mitral valve deployment resulting in less flaring of the strut into the outflow tract thereby improving the neo-LVOT area. No outflow tract obstruction occurred. The advantages of this approach as well as other alternative solutions to this problem are discussed. © 2017 Wiley Periodicals, Inc.

Congenital heart defects (CHDs) are the most common congenital defect, occurring in approximately 1 in 100 live births and being a leading cause of perinatal morbidity and mortality. Of note, approximately 25% of these defects are classified as critical, requiring immediate postnatal care by pediatric cardiology and neonatal cardiac surgery teams. Consequently, early and accurate diagnosis of CHD is key to proper prenatal and postnatal monitoring in a tertiary care setting.

Background: Current treatments for hypertrophic obstructive cardiomyopathy (HOCM), including medication, surgery, and alcohol septal ablation (ASA), have limitations in terms of efficacy and safety. To address these challenges, we developed the trans-coronary intra-septal radiofrequency ablation (TIRA) device.
Methods: This first-in-human trial was conducted to assess the efficacy and safety of the TIRA device.

Hypertrophic cardiomyopathy (HCM) is a heterogeneous group of heart muscle disorders that affects millions, with an incidence from 1 in 500 to 1 in 200. Factors such as genetics, age, gender, comorbidities, and environmental factors may contribute to the course of this disease. Diagnosis of HCM has improved significantly in the past few decades from simple echocardiographic evaluations to a more complex, multimodal approach embracing advanced imaging, genetic, and biomarker studies.

To assess the prenatal course and early postnatal outcomes of fetuses diagnosed with tricuspid atresia and to identify predictors of survival. This was a retrospective study of 25 fetuses diagnosed with tricuspid atresia in a single tertiary referral center, evaluating prenatal echocardiographic features and postnatal outcomes. A total of 4 of 29 initially diagnosed fetuses were excluded due to changes in diagnosis or loss to follow-up, leaving 25 fetuses for analysis.
