BACKGROUND: Pulmonary hypertension (PH) is an important clinical entity in dogs. Pulmonary hypertension is generally identified based on echocardiographic findings, but measurement variation of the variables most often used in this context has not been reported. OBJECTIVE: To define measurement variation of echocardiographic variables that are used to estimate pulmonary artery pressure. ANIMALS: Four dogs with subclinical tricuspid valve regurgitation were selected from a hospital population...

Background: Transcatheter aortic valve replacement (TAVR) has been shown safe and feasible in patients with bicuspid aortic valve (BAV) morphology. Evaluation of inter-ethnic differences in valve morphology and function and aortic root dimensions in patients with BAV is important for the worldwide spread of this therapy in this subgroup of patients. Comparisons between large European and Asian cohorts of patients with BAV have not been performed, and potential differences between populations may have important implications for TAVR...

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success...

OBJECTIVES: The aim of this study was to assess feasibility and clinical effectiveness of the MitraClip device in octogenarians suffering from severe mitral valve regurgitation due to chordae rupture. BACKGROUND: The MitraClip procedure is a suitable technique in high-risk surgical patients to achieve safe and effective percutaneous repair of mitral valve regurgitation. Octogenarians show cumulative risk and social aspects hindering mitral valve surgery. No data exists regarding the use of the MitraClip device in high-risk octogenarians suffering from mitral valve chordae rupture...

A previously healthy 61-year-old man presented to the emergency department with chest pain and dyspnoea for 6 hours. Examination revealed distress with an apical pansystolic murmur. Initial electrocardiogram showed sinus tachycardia and ST elevation in leads II, III, and aVF compatible with an inferior ST-elevation myocardial infarction. Point-of-care echocardiography in the emergency department showed a flail anterior mitral leaflet and severe mitral regurgitation, leading to a provisional diagnosis of papillary muscle rupture...

BACKGROUND: Parachute tricuspid valve is a rare congenital malformations explained in the literature. In most cases, this malformation coexists with other congenital defects. The importance of this condition depends on its functional consequences. CASE REPORT: First case was a 52-year-old female patient presented with palpitation. She had a history of paroxysmal supraventricular tachycardia. Transthoracic echocardiography revealed large secundum type atrial septal defect and all the tricuspid valve leaflets appeared to be connected to a single calcified papillary muscle in right ventricle suggestive of parachute tricuspid valve...

Achieving minimal residual mitral regurgitation (MR) after percutaneous MitraClip repair is limited by iatrogenic mitral stenosis. It is unknown whether allowing moderately elevated postprocedural mean mitral gradients (MMGs) to achieve < moderate residual MR is preferable to moderate residual regurgitation. Patients with less-than-moderate residual MR but a MMG of ≥5 mm Hg (Group 1) were compared with patients with moderate residual MR (Group 2). The primary end point was heart failure hospitalization...

OBJECTIVES: Diagnosing fetal heart failure remains challenging because it is difficult to know how well the fetal myocardium will perform as loading conditions change. In adult cardiology, natriuretic peptides (NPs) are established marker of heart failure. However, the number of studies investigating NP levels in fetuses is quite limited. The aim of this study was to evaluate the significance of plasma NP levels in the assessment of heart failure in fetuses with congenital heart defect (CHD) and arrhythmia...

BACKGROUND: Right ventricular dysfunction in patients with tetralogy of Fallot and significant pulmonary regurgitation may lead to systolic dysfunction of the left ventricle due to altered ventricular interaction. We were interested in determining whether chronic pulmonary regurgitation affects the preload of the left ventricle. In addition, we wanted to study whether severe chronic pulmonary regurgitation would alter the preload of the left ventricle when compared with patients having preserved pulmonary valve annulus...

BACKGROUND: Patients with congenital or acquired heart defects affecting the pulmonary valve and right ventricular outflow tract (RVOT) commonly require multiple surgical interventions, resulting in significant morbidity. A less invasive alternative is percutaneous pulmonary valve implantation (PPVI). Though studies have previously reported the safety and efficacy of the early generation transcatheter heart valves (THVs), data on more recent devices are severely lacking. METHODS AND RESULTS: We performed a multinational, multicentre, retrospective, observational registry analysis of patients who underwent PPVI using the Edwards SAPIEN XT THV...

A 30-year-old male patient presented with Glanzmann's thrombasthenia and mitral valve prolapse. He was in acute decompensated congestive heart failure due to severe mitral and tricuspid regurgitation. After his cardiac failure had been stabilized, the patient was subjected to mitral and tricuspid valve repair. His transfusion requirements were guided by thrombelastography and his bleeding disorder was managed by infusing single donor plasmapheresed platelet transfusions in the perioperative period. The patient underwent surgery uneventfully...

We discuss the case of a 24-year-old woman with Lutembacher syndrome and severe tricuspid regurgitation (TR) who underwent surgical closure of atrial septal defect and mitral valve replacement without tricuspid annuloplasty despite a severe TR and a large tricuspid annulus on preoperative echo. The pathophysiology of Lutembacher syndrome is discussed below. The utility of perioperative echocardiography in assessing the annular diameter, tenting area and coaptation depth and thus providing insights into the functioning of the tricuspid valve will also be emphasized...

Ischemic mitral regurgitation (IMR) is a frequent complication of left ventricular (LV) global or regional pathological remodeling due to chronic coronary artery disease. It is not a valve disease but represents the valvular consequences of increased tethering forces and reduced closing forces. IMR is defined as mitral regurgitation caused by chronic changes of LV structure and function due to ischemic heart disease and it worsens the prognosis. In this review, we discuss on etiology, pathophysiology, and mechanisms of IMR, its classification, evaluation, and therapeutic corrective methods of IMR...

AIMS: Videodensitometric assessment of aortography provides a periprocedural quantitation of prosthetic valve regurgitation (PVR) after transcatheter aortic valve implantation. We sought to compare the videodensitometric parameters of PVR severity to the regurgitation fraction (RF) in a controlled in-vitro setting. METHODS AND RESULTS: In a mock circulation system, a transcatheter balloon-expandable valve inserted at the aortic valve position was gradually deformed to induce different grades of paravalvular leakage and the RF was measured with a transonic flow probe...
