BACKGROUND: Takotsubo syndrome (TTS) is a heart failure syndrome which is usually reversible. Factors associated with degree of recovery of left ventricular systolic function in TTS are poorly understood. MATERIALS AND METHODS: We conducted a retrospective analysis of 90 TTS patients treated at our institution from 2006 to 2014. Patients were grouped based on recovery of left ventricular ejection fraction (LVEF) on follow-up transthoracic echocardiogram as left ventricular ejection fraction <50% (partial group) or preserved ejection fraction ≥50% (full group)...

An 87-year-old female with symptomatic severe aortic stenosis underwent transcatheter valve replacement (TAVR) via the transfemoral approach with a 29mm self-expanding device. Moderate to severe paravalvular regurgitation led to the development of congestive heart failure and hospital readmission 1 month following TAVR. A second 29mm valve was placed to abolish the paravalvular regurgitation. Routine follow-up computed tomography (CT) imaging demonstrated leaflet thickening and decreased leaflet mobility suggesting valve thrombosis, despite adherence to Factor Xa inhibitor...

We aimed to evaluate the success rates of balloon valvuloplasty post-dilation (BVPD) and a second-valve deployment in reducing residual aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and its impact on outcome. Residual AR immediately post-TAVI in patients with aortic stenosis is a common condition that adversely affects outcome. Patients who underwent TAVI who had more-than-mild residual AR were managed either with medical therapy, re-intervention with BVPD, or a second valve...

BACKGROUND: Residual aortic regurgitation (AR) following transcatheter aortic valve replacement (TAVR) is associated with adverse outcome. We sought to evaluate the efficacy and safety of second CoreValve (CV) implantation to treat residual AR following the initial CV deployment. METHODS AND RESULTS: TAVR patients treated with a second CV due to moderate and above residual AR were compared to single device implantation. Valvular function parameters were compared at baseline, post procedure, and 30 days...

BACKGROUND: Scar burden by late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is associated with functional recovery after coronary artery bypass surgery (CABG). There is limited data on long-term mortality after CABG based on left ventricular (LV) scar burden. METHODS: Patients who underwent LGE CMR between January 2003 and February 2010 within 1 month prior to CABG were included. A standard 16 segment model was used for scar quantification...

OBJECTIVES: This study sought to evaluate variability in aortic measurements with multiple imaging modalities in clinical centers by comparing with a standardized measuring protocol implemented in a core laboratory. BACKGROUND: In patients with aortic disease, imaging of thoracic aorta plays a major role in risk stratifying individuals for life-threatening complications and in determining timing of surgical intervention. However, standardization of the procedures for performance of aortic measurements is lacking...

BACKGROUND: Takotsubo syndrome is also known as stress cardiomyopathy because of the regularity with which it has been associated with physical or emotional stress. Such stress may well be a "trigger" of the syndrome. AIMS: This analysis was undertaken to describe our experience with this disorder and in particular to examine the effects of the underlying trigger on outcomes. METHODS: We conducted a retrospective review of the medical records of 345 consecutive patients treated at our institution from 2006 to 2014...

PURPOSE: Germ-line testing for panels of cancer genes using next-generation sequencing is becoming more common in clinical care. We report our experience as a clinical laboratory testing both well-established, high-risk cancer genes (e.g., BRCA1/2, MLH1, MSH2) as well as more recently identified cancer genes (e.g., PALB2, BRIP1), many of which have increased but less well-defined penetrance. METHODS: Clinical genetic testing was performed on over 10,000 consecutive cases referred for evaluation of germ-line cancer genes, and results were analyzed for frequency of pathogenic or likely pathogenic variants, and were stratified by testing panel, gene, and clinical history...

We report the case of a large right renal arteriovenous fistula (AVF) in a 74-year old woman who presented with heart failure. Transthoracic echocardiography revealed normal left ventricular size and systolic function (ejection fraction 60-65%), moderately dilated right ventricle with severely depressed systolic function, and severe pulmonary hypertension. Right heart catheterization confirmed the elevated pulmonary pressures and showed a high cardiac output. Physical examination was remarkable for a right flank bruit...

OBJECTIVES: The purpose of this study was to investigate the effects of knowledge-based iterative model reconstruction (IMR) on image quality in cardiac CT performed for the planning of redo cardiac surgery by comparing IMR images with images reconstructed with filtered back-projection (FBP) and hybrid iterative reconstruction (HIR). METHODS: We studied 31 patients (23 men, 8 women; mean age 65.1 ± 16.5 years) referred for redo cardiac surgery who underwent cardiac CT...

Patients with severe aortic stenosis and no obstructed coronary arteries are reported to have reduced coronary flow. Doppler evaluation of proximal coronary flow is feasible using transesophageal echocardiography. The present study aimed to assess the change in coronary flow in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). The left main coronary artery was visualized using transesophageal echocardiography in 90 patients undergoing TAVI using the Edwards SAPIEN valve...

OBJECTIVES: To investigate the effects of a new model-based type of iterative reconstruction (M-IR) technique, the iterative model reconstruction, on image quality of prospectively gated coronary CT angiography (CTA) acquired at low-tube-voltage. METHODS: Thirty patients (16 men, 14 women; mean age 52.2 ± 13.2 years) underwent coronary CTA at 100-kVp on a 256-slice CT. Paired image sets were created using 3 types of reconstruction, i.e. filtered back projection (FBP), a hybrid type of iterative reconstruction (H-IR), and M-IR...

Cardiac fibromas represent the second most common benign cardiac mass seen in the pediatric population, but they are rarely seen in adults. Given their large size and unpredictable location within the heart, patients may present with varying symptomatology, and in many cases, the initial presentation is sudden death. Both echocardiography and magnetic resonance imaging are critical to the early diagnosis and prompt treatment of these potentially dangerous primary tumors. We report a 29-year-old woman presenting with syncope and ventricular tachycardia...

While multi-detector cardiac computed tomography angiography (MDCCTA) prior to reoperative cardiac surgery (RCS) has been associated with improved clinical outcomes, its impact on hospital charges and length of stay remains unclear. We studied 364 patients undergoing RCS at Washington Hospital Center between 2004 and 2008, including 137 clinically referred for MDCCTA. Baseline demographics, procedural data, and perioperative outcomes were recorded at the time of the procedure. The primary clinical endpoint was the composite of perioperative death, myocardial infarction (MI), stroke, and hemorrhage-related reoperation...

OBJECTIVES: The study evaluated the relationship between cardiac computed tomography (CT) scout view x-ray attenuation and CT image noise compared with weight or body mass index (BMI). BACKGROUND: Decreasing peak tube voltage from 120 to 100 kVp on the basis of body size reduces radiation exposure. Methods to better predict CT image noise may lead to more effective selection of reduced tube voltage in cardiac CT. METHODS: Image quality was graded subjectively (1 [excellent] to 4 [nondiagnostic]) and objectively (SD of the aortic attenuation value) in cardiac CT angiograms (N = 106) acquired at either 100 or 120 kVp...
