The giant protein titin forms the "elastic" filament of the sarcomere, essential for the mechanical compliance of the heart muscle. Titin serves a biological spring, and therefore structural modifications of titin affect function of the myocardium and are associated with heart failure and cardiomyopathy.

In this review, we discuss the current understanding of titin's biophysical properties and how modifications contribute to cardiac function and heart failure. In addition, we review the most recent data on the clinical impact and phenotype heterogeneity of TTN truncating variants, including diseases involving striated muscles, and prospects for future therapies. Because of the giant structure of the titin protein and the complexity of its function, titin's role in health and disease is not yet completely understood. Future research efforts need to focus on novel therapeutic approaches able to modulate titin transcriptional and post-translational modification.

The field of transcatheter tricuspid valve interventions (TTVI) is rapidly evolving to meet a well-defined but unmet clinical need. Severe tricuspid regurgitation is common and is associated with significant morbidity and mortality. Surgical options are limited and of high risk. The success of TTVI depends on careful procedural planning, and cardiac computed tomography (CCT) plays an emerging key role.

TTVI technologies have various targets, including the leaflets, annulus, and venae cavae, along with valve replacement. Based on the planned procedure, CCT allows for device sizing, careful assessment of the access route, and comprehensive analysis of relevant adjacent anatomic structures to enhance procedural safety. It can also evaluate right-sided heart function, and its data can be for fusion imaging and 3D printing. Procedural planning is key to TTVI's success and is highly dependent on high-quality CCT data. selleck kinase inhibitor This review details the comprehensive roles of CCT, specifics of the dedicated TTVI protocol, and its limitations.

Given the low occurrence of clinically important paravalvular leak (PVL), there are no large registries or trials in this space to investigate management strategies. This review integrates newer evidence, particularly in imaging guidance for these complex procedures, novel techniques and approaches that our group has taken, as well as approaches to more complex PVL plugging reported in case reports.

Perhaps the largest area of growth in the management of PVL is the use of advanced imaging in both pre-procedure evaluation and intra-procedural guidance with gated cardiac CT, 3D TEE, and fluoroscopy fusion technologies. Outside the USA, a new device, the Occlutech PLD, has become available with early data indicating high success rates. There remains little randomized data to support the efficacy of percutaneous PVL closure. Gated cardiac CT has become key to the pre-procedure evaluation for transcatheter closure as it allows for increased procedural efficiency and more accurate pre-procedure planning, partic Intra-procedural TEE-fluoro fusion allows for more rapid crossing of defects by providing a visual target for interventionalists. The advent of purpose-built devices for PVL closure may further increase the efficacy and efficiency of percutaneous closure, but significant barriers remain for approval of these devices in the USA.
The 2015 American College of Cardiology (ACC)/American Heart Association (AHA) Focused Update of Secondary Prevention Lipid Performance Measures removed low-density lipoprotein cholesterol (LDL-C) assessment as a performance measure. This review discusses the evidence supporting the importance of lipid monitoring in the secondary prevention of atherosclerotic cardiovascular disease (ASCVD).

The 2018 AHA/ACC Multisociety cholesterol guideline (as did the 2013 guideline) recommends a lipid panel after initiating lipid-lowering therapy to monitor adherence and medication efficacy. The 2018 guideline also recommends adding nonstatin therapy in very-high-risk ASCVD patients with LDL-C ≥70 mg/dL despite maximally tolerated statin therapy. The removal of LDL-C monitoring as a performance measure is not consistent with the 2018 cholesterol guidelines. Given the importance of monitoring lipid-lowering medication efficacy and adherence and optimally reducing LDL-C in very-high-risk patients with additional evidence-based nonstatin therapy, LDL-C assessment after initiating lipid-lowering therapy should be reinstated as a performance measure for patients with ASCVD.
