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.

Transfemoral Transcatheter Aortic Valve Replacement Using Fascia Iliaca Block as an Alternative Approach to Conscious Sedation as Compared to General Anesthesia.

Background/purpose: General Anesthesia (GA) and conscious sedation (CS) are anesthetics for transfemoral transcatheter aortic valve replacement (TF-TAVR). We compared TF-TAVR outcomes using a novel anesthetic approach with fascia iliaca block (FIB) plus minimal CS (MCS) versus GA.

Methods: This retrospective propensity-matched study included consecutive TF-TAVR patients from January 2013 to December 2017 and dichotomized into FIB-MCS vs.

Clinical Conference Proceedings: 15th Biennial International Andreas Gruentzig Society Meeting.

The International Andreas Gruentzig Society is an educational society of physicians and scientists interested in cardiovascular and related fields. Members cooperate in the advancement of knowledge and education through research, publication, study, and teaching in the fields of cardiovascular disease. This summary reflects the proceedings from the recent scientific meeting to assess current clinical problems and propose future directions and possible solutions.

Minimizing radiographic contrast administration during coronary angiography using a novel contrast reduction system: A multicenter observational study of the DyeVert™ plus contrast reduction system.

Objective: To evaluate contrast media (CM) volume (CMV) saved using the DyeVert™ Plus Contrast Reduction System (DyeVert Plus System, Osprey Medical) in patients undergoing diagnostic coronary angiogram (CAG) and/or percutaneous coronary interventional (PCI) procedures performed with manual injections.

Background: Current guidelines advocate for monitoring and minimization of the total volume of CM in chronic kidney disease (CKD) patients undergoing invasive cardiac procedures. The DyeVert Plus System is an FDA cleared device designed to reduce CMV delivered during angiography and permit real-time CMV monitoring.

Emergency Valve-in-Valve Transcatheter Aortic Valve Implantation for the Treatment of Acute Stentless Bioprosthetic Aortic Insufficiency and Cardiogenic Shock.

Bioprosthetic aortic valve degeneration may present as acute, severe aortic regurgitation and cardiogenic shock. Such patients may be unsuitable for emergency valve replacement surgery due to excessive risk of operative mortality but could be treatable with transfemoral valve-in-valve transcatheter aortic valve implantation (TAVI). There is a paucity of data regarding the feasibility of valve-in-valve TAVI in patients presenting with cardiogenic shock due to acute aortic insufficiency from stentless bioprosthetic valve degeneration.

Prioritizing and Combining Therapies for Heart Failure in the Era of Mechanical Support Devices.

Technological advances have promoted challenges to prioritizing and combining therapies for heart failure. The concept of prioritization implies distinct but inextricably linked considerations. They may be viewed from pathophysiologic, clinical, and procedural perspectives, encompassing analysis of hemodynamic status, anatomic considerations, and technical challenges.

Psoas Muscle Area as a Predictor of Outcomes in Transcatheter Aortic Valve Implantation.

Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty before surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution from 2011 to 2014.

Mitral valve repair after annuloplasty ring dehiscence using MitraClip.

Dehiscence of a surgical mitral annuloplasty ring for repair of functional mitral regurgitation (MR) is an infrequently reported complication that often manifests as recurrent MR and heart failure. Re-do mitral valve surgery to correct ring dehiscence may not be feasible for patients at high risk of operative mortality or serious morbidity. We report two cases of mitral annular ring dehiscence and severe mitral regurgitation in patients at prohibitive risk for re-do mitral valve surgery who were successfully treated with MitraClip.

Analysis of target lesion length before coronary artery stenting using angiography and near-infrared spectroscopy versus angiography alone.

Lipid core plaque (LCP) can extend beyond the angiographic margins of a target lesion, potentially resulting in incomplete lesion coverage. We sought to compare the target lesion length using near-infrared spectroscopy (NIRS) combined with conventional coronary angiography versus angiography alone. NIRS was performed in 69 patients (75 lesions) undergoing native vessel percutaneous coronary intervention (LipiScan Coronary Imaging System).
