OBJECTIVES: The aim of this study was to systematically evaluate the incidence of infective endocarditis (IE) in right ventricle-to-pulmonary artery conduits and valves, comparing bovine jugular vein (BJV) valves with all others. BACKGROUND: Recent evidence suggests that the incidence of IE is higher in patients with congenital heart disease who have undergone implantation of BJV valves in the pulmonary position compared with other valves. METHODS: Systematic searches of published research were conducted using electronic databases (MEDLINE, Embase, and CINAHL) and citations cross-referenced current to April 2016...

BACKGROUND: The status of intrinsic left ventricular (LV) contractility in patients with isolated rheumatic mitral stenosis (MS) has been debated. The acute changes in loading conditions after percutaneous mitral valvuloplasty (PMV) may affect LV performance. We aimed to examine the acute effects of PMV on LV function and identify factors associated with LV ejection fraction (LVEF) changes, and determinants of long-term events following the procedure. METHODS: One hundred and forty-two patients who underwent PMV for symptomatic rheumatic MS (valve area of 0...

Mitral valve repair with the MitraClip device has emerged as an effective treatment option for patients with severe mitral regurgitation and contraindications for surgical interventions. While the procedure is not known to cause pulmonary complications, we describe two cases of pulmonary hemorrhage following percutaneous mitral valve repair. The patients did well with supportive care and reinitiation of anticlotting agents was well tolerated after resolution of bleeding.

The effect of percutaneous mitral valve repair using the MitraClip system on tricuspid regurgitation (TR) has not been well investigated. We retrospectively analyzed 102 consecutive patients who underwent the successful MitraClip procedure, and who also had a preprocedural and 1-year follow-up transthoracic echocardiography. TR severity was graded by standard guideline-recommended criteria. At 1 year after the MitraClip procedure, the degree of TR regressed (at least 1 grade) in 23% of the patients, was unchanged in 62% of the patients, and progressed in 16% of the patients...

PURPOSE OF REVIEW: Pulmonary valve is the least imaged of the cardiac valves in adults. This review will address the strengths and the limitations of various imaging modalities that are commonly used for evaluation of pulmonary valve diseases in the adults. RECENT FINDINGS: Valvular pulmonary stenosis is mostly congenital and pulmonary regurgitation is usually an acquired pulmonary valve disease. Combined pulmonary stenosis and pulmonary regurgitation as sequel to previous surgeries for congenital heart diseases is the most common form of pulmonary valve disease in the adults...

Percutaneous edge-to-edge repair using the MitraClip system causes reduction in mitral valve area (MVA). However, its clinical impact is not fully elucidated. This study assessed the impact of postprocedural MVA reduction on pulmonary hypertension and outcomes. A total of 92 patients with grades 3 to 4 + mitral regurgitation (MR) who underwent MitraClip therapy were retrospectively reviewed. Using intraprocedural, 3-dimensional transesophageal echocardiography, postprocedural MVA was obtained by 2 optimized planes through the medial and lateral orifices of the repaired valve...

Takotsubo cardiomyopathy describes a sudden onset cardiomyopathy with acute impairment of left ventricular function and spontaneous resolution over time. Only a few cases of Takotsubo cardiomyopathy in childhood have been described. We report the case of a 12-year-old girl with repaired tetralogy of Fallot who experienced acute onset of left ventricular dysfunction without coronary arterial involvement, suggesting Takotsubo cardiomyopathy, during an interventional catheterization procedure. Cardiogenic shock necessitated mechanical circulatory support with extracorporeal membrane oxygenator for ten days and mechanical ventilation for 12 days...

Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves...

Recent data showed a right ventricular dyssynchrony in patients with tetralogy of Fallot (TOF). Percutaneous pulmonary valve implantation (PPVI) has become an important procedure to treat a pulmonary stenosis and/or regurgitation of the right ventricular outflow tract in these patients. Despite providing good results, there is still a considerable number of nonresponders to PPVI. The authors speculated that electrical dysfunction of the right ventricle plays an underestimated role in the outcome of patients after PPVI...

Introduction Percutaneous balloon valvuloplasty is the primary treatment for critical pulmonary valve stenosis in neonates. Thus far, a few studies have reported long-term results of this technique in neonatal critical pulmonary valve stenosis. METHODS: We carried out a retrospective study of all consecutive newborns with critical pulmonary valve stenosis subjected to percutaneous balloon valvuloplasty at a single centre, between 1994 and 2014, to assess its immediate and long-term safety and efficacy...

AIM: Longitudinal ventricular contraction is a parameter of cardiac performance with predictive power. Right ventricular longitudinal function is impaired in patients with free pulmonary regurgitation (PR) following corrective surgery for Tetralogy of Fallot (TOF). It remains unclear whether this is a consequence of the surgical repair, or whether it is inherent to PR. The aim of this study was to assess the relationship between longitudinal, lateral and septal pumping in a porcine model of isolated PR...

This case describes a complication of bone cement use. A 65-year-old male patient with back spine trauma caused by a fall, underwent a percutaneous vertebroplasty. Five years later, he consulted for palpitations, and the electrocardiogram showed supraventricular arrhythmia. A transthoracic two-dimensional echocardiography showed a hyperechogenic linear structure of 7 cm length, running from the lateral wall of the right ventricle to the right atrium through the tricuspid valve. This foreign body, which was suspicious for bone cement embolism, appeared rigid and was attached at the lateral wall of the right ventricle, with its proximal end free in the right atrium...

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

Aortic regurgitation (AR) is characterized by the backflow of blood from the aorta to the left ventricle. Acute AR typically causes severe pulmonary edema and hypotension, and is a surgical emergency. In chronic AR, however, compensatory mechanisms can clinically compensate for years, with normal left ventricular function and no symptoms. While the hemodynamic mechanisms of chronic AR on the left ventricle are well described, the hemodynamic mechanisms of acute AR are not clear. Most of the literature on acute AR includes either small series or case reports...

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT)...
