Percutaneous pulmonary valve intervention (PPVI) is a less invasive and less costly approach to pulmonary valve replacement compared with the surgical alternative. Potential complications of PPVI include coronary compression and pulmonary arterial injury/rupture. The purpose of this study was to characterize the morphological risk factors for PPVI complication with cardiac MRI and cardiac CTA. A retrospective review of 88 PPVI procedures was performed. 44 patients had preprocedural cardiac MRIs or CTAs available for review...

The robotic approach to cardiac surgery offers patients numerous potential advantages compared with a traditional sternotomy approach including shorter hospital length of stay, reduced pain, fewer blood transfusions, and a quicker return to normal daily activities. At the same time, robotic cardiac surgery requires that the anesthesiologist employs several subspecialty skillsets in order to provide optimal care for these patients. Multiple different regional anesthesia techniques may be used to improve analgesia, reduce opioid dosages, and facilitate rapid extubation at the conclusion of the case...

BACKGROUND: Successful percutaneous mitral valve repair (PMVR) in patients with severe mitral regurgitation (MR) causes changes in hemodynamics. Echocardiographic calculation of cardiac output (CO) has not been evaluated in the setting of PMVR, so far. Here we evaluated hemodynamics before and after PMVR with the MitraClip system using pulmonary artery catheterization, transthoracic (TTE) and transesophageal (TEE) echocardiography. METHODS: 101 patients with severe MR not eligible for conventional surgery underwent PMVR...

BACKGROUND: Surgical and transcatheter bioprosthetic valves (BPVs) in the pulmonary position in patients with congenital heart disease may ultimately fail and undergo transcatheter reintervention. Angiographic assessment of the mechanism of BPV failure has not been previously described. AIMS: The aim of this study was to determine the mode of BPV failure (stenosis/regurgitation) requiring transcatheter reintervention and to describe the angiographic characteristics of the failed BPVs and report the types and efficacy of reinterventions...

Balloon-expandable percutaneous pulmonary valve systems using the Melody and Edwards SAPIEN transcatheter heart valves have been increasingly used instead of surgically implantable pulmonary valves. However, limited patients with right ventricular outflow tract (RVOT) lesions are suitable candidates for percutaneous pulmonary valve implantation (PPVI) using these systems after surgical correction of tetralogy of Fallot. Therefore, larger self-expandable valved-stents are being developed for native RVOT lesions...

INTRODUCTION: There is scarce information about right ventricle (RV) function in patients with secondary pulmonary hypertension (PH) undergoing transcatheter aortic valve implantation (TAVI). We aim to identify possible RV abnormalities in patients referred for TAVI with severe aortic stenosis (sAS) and secondary PH. METHODS: Objective measures of RV function, as well as noninvasive estimates of pulmonary artery systolic pressures (PASP) were obtained from 30 sAS patients undergoing percutaneous valve intervention...

BACKGROUND: The change in the level of NT-Pro-BNP (N-terminal Pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-Pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-Pro BNP reduction and post-PTMC echocardiography parameters...

PURPOSE: Patients with thoracic malignancies often have more than one site of pulmonary, nodal or pleural disease within one hemithorax. In addition, large heterogeneous lesions may comprise distinct, mixed pathological entities. Histological analysis of these lesions can alter tumour staging and treatment options. We investigated the feasibility, safety and benefit of performing image-guided percutaneous lung biopsy (PLB) of two lesions in the same hemithorax at a single sitting. MATERIALS AND METHODS: Ten consecutive outpatients with two or more potential disease foci within the same hemithorax were analysed over a 15-month period...

INTRODUCTION: The mitral valve area (MVA) poorly reflects the hemodynamic status of (MS). In this study, we compared the MVA with mitral valve resistance (MVR) with regard to the determination of hemodynamic consequences of MS and the immediate outcomes of percutaneous balloon mitral valvuloplasty (PBMV). METHODS: In a prospective study, 36 patients with severe rheumatic MS with left ventricular ejection fraction (LVEF) >50% were evaluated. They underwent transthoracic echocardiography (TTE) and catheterization...

BACKGROUND: The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. AIM: To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. METHODS: From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged<18 years), and were followed for echocardiographic homograft stenosis (peak gradient>36mmHg) and surgical or percutaneous homograft reintervention...

BACKGROUND: Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating from enterochromaffin cells and secreting mainly serotonin. The diagnosis is based on clinical symptoms, hormone blood levels, radiological and nuclear imaging, and histological confirmation. However, most patients have metastases at the time of diagnosis because the clinical signs often remain unnoticed or are attributed to other abdominal conditions. In up to 50% of patients the endocardium is affected due to a hormonally active tumor profile...

Carcinoid heart disease is a rare but important cause of intrinsic right heart valve disorders leading to right heart failure. Occasionally, left-sided heart valves may also be involved. The characteristic cardiac pathological findings of carcinoid heart disease are endocardial thickening as a result of fibrous deposits on the endocardium. Echocardiographic examination and right heart catheterization are very useful for the diagnosis of the lesion. If more cardiac valves are affected, multiple valve replacement should be considered...

More than half of patients with carcinoid syndrome develop carcinoid valve disease. Both the tricuspid and pulmonary valve are often involved. Symptoms of carcinoid syndrome with flushing, diarrhea, and bronchospasm often precedes cardiac symptoms. We report a case of carcinoid initially presenting with rapid development of right heart failure due to severe pulmonary valve stenosis. In untreated carcinoid, there is a risk of carcinoid crisis with anesthesia and surgery. In local anesthesia, we performed a sub-acute balloon pulmonary valvuloplasty...

INTRODUCTION: Three-dimensional rotational angiography (3DRA) has been used in the guidance of various transcatheter therapies including percutaneous pulmonary valve implantation (PPVI). The most recently available 3D image fusion software (VesselNavigator, Philips) extends this technology to use pre-registered computed tomography or magnetic resonance imaging datasets, promising reductions in contrast and radiation exposure along with shorter procedural times. METHODS: In this retrospective review, patients were assigned to three groups according to the mode of imaging guidance: two-dimensional angiography (2DA), 3DRA and VesselNavigator (VN) assisted valve implantation...

INTRODUCTION: The Venus p‑valve (MedTech, Shanghai, China) is a self-expanding percutaneous heart valve designed to be implanted in a native patched right ventricle outflow tract. The worldwide clinical experience with this valve is just beginning and the results have so far been encouraging. We present our initial early experience implanting the Venus p‑valve in the native right ventricle outflow tract of patients with Tetralogy of Fallot repaired with a transannular patch. METHODS: In 10 selected patients a procedure for percutaneous pulmonary valve implantation was performed using the Venus p‑valve...
