Outcomes of Suction Debulking and Surgery in Patients With Isolated Tricuspid Valve Endocarditis.

Objective: Percutaneous vegetation debulking has been reported to treat tricuspid valve infective endocarditis (TVIE), but data on feasibility compared with conventional surgical strategies are limited. We aimed to compare short-term outcomes of suction debulking with partial venovenous bypass to conventional open surgery in this population.

Methods: This was a single-center, retrospective study that included all patients with isolated TVIE who underwent suction debulking with partial venovenous bypass or tricuspid valve surgery between January 2010 and December 2022.

Impact of Tricuspid Regurgitation on Outcomes After Transcatheter Mitral Valve Replacement.

Development of functional tricuspid regurgitation (TR) because of chronic mitral disease and subsequent heart failure is common. However, the effect of TR on clinical outcomes after transcatheter mitral valve replacement (TMVR) remains unclear. We aimed to evaluate the impact of baseline TR on outcomes after TMVR.

Transcatheter Myotomy to Reduce Left Ventricular Outflow Obstruction.

Background: Left ventricular outflow tract (LVOT) obstruction is a source of morbidity in hypertrophic cardiomyopathy (HCM) and a life-threatening complication of transcatheter mitral valve replacement (TMVR) and transcatheter aortic valve replacement (TAVR). Available surgical and transcatheter approaches are limited by high surgical risk, unsuitable septal perforators, and heart block requiring permanent pacemakers.

Objectives: The authors report the initial experience of a novel transcatheter electrosurgical procedure developed to mimic surgical myotomy.

Transcatheter Paravalvular Leak Closure With Covered Stent Tract and Vascular Plug: Tootsie Roll Technique.

Background: Transcatheter closure of transcatheter heart valve (THV)-related paravalvular leak (PVL) is associated with a high failure rate with available devices due to the complex interaction of THV and aortic/mitral annulus.

Objectives: This study reports on novel transcatheter techniques to treat PVL after THV.

Methods: The authors describe consecutive patients who underwent PVL closure after transcatheter aortic valve replacement (TAVR) or transcatheter mitral valve replacement (TMVR).

Hybrid Closure of Postinfarction Apical Ventricular Septal Defect Using Septal Occluder Device and Right Ventricular Free Wall: The Apical BASSINET Concept.

Background: Postinfarction ventricular septal defect (VSD) is a catastrophic complication of myocardial infarction. Surgical repair still has poor outcomes. This report describes clinical outcomes after a novel hybrid transcatheter/surgical repair in patients with apical VSD.

The Art of SAPIEN 3 Transcatheter Mitral Valve Replacement in Valve-in-Ring and Valve-in-Mitral-Annular-Calcification Procedures.

The SAPIEN 3 is the only transcatheter heart valve commercially available for compassionate transcatheter mitral valve replacement in patients with previous mitral surgical rings and mitral annular calcification (valve in ring [VIR] and valve in mitral annular calcification [VIM]). Reported outcomes have been inconsistent or poor. The review provides an overview of the authors' approach to achieve largely consistent results despite the intrinsic limitations of SAPIEN 3 VIM and VIR.

Omission of Heart Transplant Recipients From the Appropriate Use Criteria for Revascularization and the Ramifications on Heart Transplant Centers.

Importance: Guidelines endorse routine coronary angiography and percutaneous coronary intervention (PCI) to screen for and treat cardiac allograft vasculopathy in heart transplant recipients. However, the current Appropriate Use Criteria for Revascularization (AUC-R) do not recognize prior heart transplant as a unique PCI indication. Whether this affects rates of rarely appropriate (RA) PCIs is unknown.

Medical Therapy Utilization and Long-Term Outcomes Following Percutaneous Coronary Intervention: Five-Year Results From the Veterans Affairs Clinical Assessment, Reporting, and Tracking System Program.

Background: Optimal medical therapy is endorsed by national guidelines in the management of ischemic heart disease; however, few studies have examined its long-term utilization following percutaneous coronary intervention (PCI) and association with clinical outcomes. We sought to assess longitudinal trends in medical therapy use after PCI and its prognostic significance.

Methods And Results: From the Veteran Affairs Clinical Assessment, Reporting, and Tracking System Program, we retrospectively identified 57 900 Veteran's Affairs patients undergoing PCI from January 2005 to May 2014.

Superior Risk Stratification With Coronary Computed Tomography Angiography Using a Comprehensive Atherosclerotic Risk Score.

Objectives: This study was designed to assess the prognostic value of a new comprehensive coronary computed tomography angiography (CTA) score compared with the stenosis severity component of the Coronary Artery Disease-Reporting and Data System (CAD-RADS).

Background: Current risk assessment with coronary CTA is mainly focused on maximal stenosis severity. Integration of plaque extent, location, and composition in a comprehensive model may improve risk stratification.

Sex differences in calcified plaque and long-term cardiovascular mortality: observations from the CAC Consortium.

Aims: Pathologic evidence supports unique sex-specific mechanisms as precursors for acute cardiovascular (CV) events. Current evidence on long-term CV risk among women when compared with men based on measures of coronary artery calcium (CAC) remains incomplete.

Methods And Results: A total of 63 215 asymptomatic women and men were enrolled in the multicentre, CAC Consortium with median follow-up of 12.

The Coronary Artery Disease-Reporting and Data System (CAD-RADS): Prognostic and Clinical Implications Associated With Standardized Coronary Computed Tomography Angiography Reporting.

Objectives: This study sought to assess clinical outcomes associated with the novel Coronary Artery Disease-Reporting and Data System (CAD-RADS) scores used to standardize coronary computed tomography angiography (CTA) reporting and their potential utility in guiding post-coronary CTA care.

Background: Clinical decision support is a major focus of health care policies aimed at improving guideline-directed care. Recently, CAD-RADS was developed to standardize coronary CTA reporting and includes clinical recommendations to facilitate patient management after coronary CTA.

Heterogeneity of signal transduction by Na-K-ATPase α-isoforms: role of Src interaction.

Of the four Na-K-ATPase α-isoforms, the ubiquitous α1 Na-K-ATPase possesses both ion transport and Src-dependent signaling functions. Mechanistically, we have identified two putative pairs of domain interactions between α1 Na-K-ATPase and Src that are critical for α1 signaling function. Our subsequent report that α2 Na-K-ATPase lacks these putative Src-binding sites and fails to carry on Src-dependent signaling further supported our proposed model of direct interaction between α1 Na-K-ATPase and Src but fell short of providing evidence for a causative role.

Prognostic Significance of Nonobstructive Left Main Coronary Artery Disease in Women Versus Men: Long-Term Outcomes From the CONFIRM (Coronary CT Angiography Evaluation For Clinical Outcomes: An International Multicenter) Registry.

Background: Patients with obstructive (≥50% stenosis) left main (LM) coronary artery disease (CAD) are at high risk for adverse events; prior studies have also documented worse outcomes among women than men with severe multivessel/LM CAD. However, the prognostic significance of nonobstructive (1%-49% stenosis) LM CAD, including sex-specific differences, has not been previously examined.

Methods And Results: In the long-term CONFIRM (Coronary CT Angiography Evaluation For Clinical Outcomes: An International Multicenter) registry, patients underwent elective coronary computed tomographic angiography for suspected CAD and were followed for 5 years.

The elusive role of myocardial perfusion imaging in stable ischemic heart disease: Is ISCHEMIA the answer?

The assessment of ischemia through myocardial perfusion imaging (MPI) is widely accepted as an index step in the diagnostic evaluation of stable ischemic heart disease (SIHD). Numerous observational studies have characterized the prognostic significance of ischemia extent and severity. However, the role of ischemia in directing downstream SIHD care including coronary revascularization has remained elusive as reductions in ischemic burden have not translated to improved clinical outcomes in randomized trials.

Can Functional Testing for Ischemia and Viability Guide Revascularization?

Cardiac imaging procedures are a cornerstone of the diagnosis and management of patients with cardiac disease. The optimal management of the patient with stable ischemic heart disease or ischemic heart failure often rests on the totality of symptom burden, patient risk, and disease severity, whether assessed anatomically or functionally. Recent trials have demonstrated the power of flow measurements to direct revascularization as well as the strengths and limitations of ischemia and viability/hibernation imaging as markers of risk to direct interventions.

Effect of Chronic Kidney Disease on Mortality in Patients Who Underwent Lower Extremity Peripheral Vascular Intervention.

It is known that chronic kidney disease (CKD) is associated with increased postoperative morbidity and mortality in patients with peripheral artery disease who underwent lower extremity surgical revascularization; however, outcomes after peripheral vascular intervention (PVI) are less well established. This study sought to determine the impact of CKD on adverse outcomes in patients with peripheral artery disease who underwent PVI. Using data from the Veteran Affairs Clinical Assessment, Reporting, and Tracking System Program, we identified a cohort of 755 patients who underwent lower extremity PVI from June 2005 to August 2010 at 33 sites.

Optimising diagnostic accuracy with the exercise ECG: opportunities for women and men with stable ischaemic heart disease.

Unlabelled: The exercise ECG is an integral part within the evaluation algorithm for diagnosis and risk stratification of patients with stable ischaemic heart disease (SIHD). There is evidence, both older and new, that the exercise ECG can be an effective and cost-efficient option for patients capable of performing at maximal levels of exercise with suitable resting ECG findings. In this review, we will highlight the major dilemmas in interpreting suspected coronary artery disease symptoms in women and identify optimal strategies for employing exercise ECG as a first-line diagnostic test in the SIHD evaluation algorithm.
