Mitochondrial Cardiomyopathy: Distinctive Cardiac Phenotype Detected with Cardiovascular MRI.

Left ventricular hypertrophy (LVH) has a broad differential diagnosis. Pathogenic variants of mitochondrial DNA are a rare cause of LVH, and cardiac MRI is a powerful technique that may aid in differentiating such rare causes. This case report presents three siblings with a pathogenic variant of the mitochondrially encoded tRNA isoleucine gene.

Upper Extremity Function following Transradial Percutaneous Coronary Intervention: Results of the ARCUS Trial.

Objectives: To determine the incidence of upper extremity dysfunction (UED), after a transradial percutaneous coronary intervention (TR-PCI).

Background: Transradial approach (TRA) is the preferred approach for coronary interventions. However, upper extremity complications may be underreported.

Predictive Value of the DASH Tool for Upper Extremity Dysfunction Following Percutaneous Coronary Intervention.

Purpose: The use of the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and its shortened version, the DASH, have been used to assess upper extremity function following a transradial percutaneous coronary intervention (TR-PCI). However, the use of these scores has not yet been validated for TR-PCI induced complications in the upper extremity. The aim of this study was to establish the validity of the DASH and the DASH, for the assessment of upper extremity dysfunction following a transradial percutaneous coronary intervention (TR-PCI).

The effect of trastuzumab on cardiac function in patients with HER2-positive metastatic breast cancer and reduced baseline left ventricular ejection fraction.

We investigated the effect of trastuzumab on cardiac function in a real-world historic cohort of patients with HER2-positive metastatic breast cancer (MBC) with reduced baseline left ventricular ejection fraction (LVEF). Thirty-seven patients with HER2-positive MBC and baseline LVEF of 40% to 49% were included. Median LVEF was 46% (interquartile range [IQR] 44%-48%) and median follow-up was 18 months (IQR 9-34 months).

Treatment and Management of Upper Extremity Dysfunction Following Transradial Percutaneous Coronary Intervention: A Prospective Cohort Study.

Background: The transradial artery access is the benchmark approach in transradial percutaneous coronary intervention (TR-PCI). The purpose of this study was to evaluate the different complications, treatments, and outcome of upper extremity dysfunction following a TR-PCI.

Methods: This was a prospective cohort substudy of patients with access-site complications.
