Echocardiographic parameters associated with less reverse left ventricular remodeling after transcatheter aortic valve implant in subjects with prosthesis patient mismatch.

Background: Transaortic valve implant (TAVI) is the treatment of choice for severe aortic stenosis (AS). Some patients develop prosthesis patient mismatch (PPM) after TAVI. It is challenging to determine which patients are at risk for clinical deterioration.

Percutaneous coronary intervention for ventricular fibrillation in the setting of an anomalous right coronary artery.

We present a case of a quadriplegic male who developed ventricular fibrillation associated with an anomalous aortic origin of the right coronary artery. Successful revascularization was achieved with percutaneous coronary intervention. This case highlights the application of an unconventional approach to resolve ischemia in a patient with prohibitive surgical risk.

Race-Specific Impact of Conventional Surgical Risk Score on 1-Year Mortality After Transcatheter Aortic Valve Replacement.

Background: Interracial differences in the distribution and prognostic value of conventional Society of Thoracic Surgeons (STS) score on long-term mortality after transcatheter aortic valve replacement (TAVR) are uncertain.

Objectives: This study aims to compare the impact of STS scores on clinical outcomes at 1-year after TAVR between Asian and non-Asian populations.

Methods: We used the Trans-Pacific TAVR (TP-TAVR) registry, a multinational multicenter, observational registry involving patients undergoing TAVR at 2 major centers in the United States and 1 major center in Korea.

Inter-racial differences in patients undergoing transcatheter aortic valve implantation.

Objective: Little information exists about inter-racial differences in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). We investigated whether differences in baseline characteristics between Asian and non-Asian population may contribute to disparities in clinical outcomes after TAVI.

Methods: We performed a registry-based, multinational cohort study of patients with severe AS who underwent TAVI at two centres in the USA and one centre in South Korea.

Racial Differences in the Incidence and Impact of Prosthesis-Patient Mismatch After Transcatheter Aortic Valve Replacement.

Objectives: The aim of this study was to compare the incidence and prognostic significance of prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) according to racial groups.

Background: PPM after TAVR may be of more concern in Asian populations considering their relatively small annular and valve sizes compared with Western populations.

Methods: TP-TAVR (Transpacific TAVR Registry) was an international multicenter cohort study of patients with severe aortic stenosis who underwent TAVR in the United States and South Korea from January 2015 to November 2019.

Impact of Loop Diuretic Use on Outcomes Following Transcatheter Aortic Valve Implantation.

The use of LDT may signify significant hemodynamic changes and left ventricular remodeling in severe aortic stenosis (AS). Therefore, we sought to determine whether loop diuretic therapy (LDT) is associated with adverse outcomes following transcatheter aortic valve implantation (TAVI) in patients with severe symptomatic AS. Subjects undergoing TAVI at a single institution from June 2008 to December 2017 were analyzed.

Transcatheter Aortic Valve Replacement Outcomes Based on the Presence of Chronic Total Occlusion.

Aims: Chronic total occlusion (CTO) has been linked to worse survival. While controversial and limited to observational data, successful CTO percutaneous coronary intervention (PCI) has been associated with improved left ventricular (LV) function and mortality. However, the role of CTO PCI prior to transcatheter aortic valve replacement (TAVR) is not clear.

Interactive Multimodal Curriculum on Use and Interpretation of Inpatient Telemetry.

Introduction: Inpatient telemetry monitoring is a commonly used technology designed to detect and monitor life-threatening arrhythmias. However, residents are rarely educated in the proper use and interpretation of telemetry monitoring.

Methods: We developed a training module containing an educational video, PowerPoint presentation, and hands-on interactive learning session with a telemetry expert.

Conduction recovery following pacemaker implantation after transcatheter aortic valve replacement.

Background: Transcatheter aortic valve replacement (TAVR) is increasingly used to treat severe aortic stenosis. A frequent complication of TAVR is high-grade or complete atrioventricular (AV) block requiring a permanent pacemaker (PPM). There are little data on the long-term dependency on pacing after TAVR.

The transition from transesophageal to transthoracic echocardiography during transcatheter aortic valve replacement: an evolving field.

The advent of transcatheter aortic valve replacement (TAVR) has dramatically transformed the clinical approach to severe aortic stenosis. Over the last decade, several trials have shown the equivalence or even superiority of transcatheter valve replacement over the conventional surgical approach. As a result, TAVR as a treatment for severe, symptomatic aortic stenosis has rapidly extended from inoperable or prohibited-risk patients to intermediate-risk patients.

Effect of Trainee Performance Data on Standard-Setting Judgments Using the Mastery Angoff Method.

Background: Mastery learning in health professions education requires learners to learn and undergo assessment until they demonstrate a high level of competence. Setting defensible standards is key to accurately assessing educational outcomes in mastery learning. The Mastery Angoff method was proposed recently to set a minimum passing standard (MPS) for mastery learning curricula.

Discordance between lipoprotein particle number and cholesterol content: an update.

Purpose Of Review: The cholesterol content within atherogenic apolipoprotein-B (apoB) containing lipid particles is the center of consensus guidelines and clinicians' focus whenever evaluating a patient's risk for atherosclerotic cardiovascular disease. The pathobiology of atherosclerosis requires the retention of lipoprotein particles within the vascular intima over time followed by maladaptive inflammation resulting in plaque formation and rupture in some. The cholesterol content is widely variable within each particle creating either cholesterol-deplete or cholesterol-enriched particles.

Complications of thoracentesis: incidence, risk factors, and strategies for prevention.

Purpose Of Review: Although thoracentesis is generally considered safe, procedural complications are associated with increased morbidity, mortality, and healthcare costs. In this article, we review the risk factors and prevention of the most common complications of thoracentesis including pneumothorax, bleeding (chest wall hematoma and hemothorax), and re-expansion pulmonary edema.

Recent Findings: Recent data support the importance of operator expertise and the use of ultrasound in reducing the risk of iatrogenic pneumothorax.
