Despite optimal medical management, some patients with severe right ventricular failure fail to respond and may benefit from additional support with the implantation of a RV assist device. Experience to date with Impella RP is limited. We report a case of percutaneous Impella RP implantation, using a parallel stiff wire to reduce anatomical tortuosity by acting as a buddy-wire to facilitate device implantation and reduce the risk of tricuspid ring damage in a patient recently treated with tricuspid ring annuloplasty...

The aims of this study are to evaluate the long-term outcomes of double valve replacement (aortic and mitral valves) and to investigate the determinants of late tricuspid regurgitation (TR). A total of 239 consecutive patients who underwent double valve replacement were enrolled. Valve pathology was rheumatic in 86.6% (207/239) and degenerative in 13.4% (32/239) of patients. Among these patients, 116 patients underwent concomitant tricuspid annuloplasty, and follow-up was completed for all 239 patients (mean = 7...

Aims: To evaluate coronary sinus single-site (CSSS) left ventricular pacing in adult patients with normal left ventricular ejection fraction (LVEF) when traditional right ventricular lead implantation is not feasible or is contraindicated. Methods and results: We performed a retrospective analysis of 23 patients with tricuspid valve surgery/disease who received a CSSS ventricular pacing lead to avoid crossing the tricuspid valve. Two matched control populations were obtained from patients receiving (i) conventional right ventricular single-site (RVSS) leads and (ii) coronary sinus leads for cardiac resynchronization therapy (CSCRT)...

Functional tricuspid regurgitation (FTR) is common, whether in association with mitral or aortic valve disease or presenting as an isolated valvular disease. Several studies have shown that TR is associated with poor patient outcomes, though a cause-and-effect relationship of TR to mortality has not been proven. Similarly the impact of surgical treatment of TR on outcomes needs well-controlled randomized trials that are under planning. The current professional society guidelines for treatment of TR are based on expert opinions with a level of evidence C for all indications...

Background -Current surgical and medical treatment options for severe tricuspid regurgitation (TR) are limited and additional interventional approaches are required. In the present observational study, the safety and feasibility of transcatheter repair of chronic severe TR with the MitraClip system were evaluated. In addition, the effects on clinical symptoms were assessed. Methods -Patients with heart failure symptoms and severe TR on optimal medical treatment were treated with the MitraClip system. Safety, defined as periprocedural adverse events such as death, myocardial infarction, stroke, or cardiac tamponade, and feasibility, defined as successful implantation of one or more MitraClip devices and reduction of TR by at least one grade, were evaluated before discharge and after 30 days...

OBJECTIVE: Although having the same ability to permit unidirectional flow within the heart, the four main valves-the mitral valve (MV), aortic (AV), tricuspid (TV) and pulmonary (PV) valves-experience different loading conditions; thus, they exhibit different structural integrity from one another. Most research on heart valve mechanics have been conducted mainly on MV and AV or an individual valve, but none quantify and compare the mechanical and structural properties among the four valves from the same aged patient population whose death was unrelated to cardiovascular disease...

Infectious endocarditis (IE), a complication that is both cardiac and infectious, occurs frequently and is associated with a heavy burden of morbidity and mortality in chronic hemodialysis patients (CHD). About 2-6% of chronic hemodialysis patients develop IE and the incidence is 50-60 times higher among CHD patients than in the general population. The left heart is the most frequent location of IE in CHD and the different published series report a prevalence of left valve involvement varying from 80% to 100%...

Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. The natural history of untreated significant TR portends an unfavourable outcome, but only a minority of patients is currently referred for surgical treatment. Organic TR (caused by primary abnormality of the leaflets) is relatively infrequent whereas secondary or functional TR (caused by dilatation of the tricuspid annulus, right ventricle [RV] and right atrium) is the predominant mechanism. The success of transcatheter therapies for left valvular heart disease over the last decade, has fuelled similar development of novel transcatheter devices for the treatment of TR...

BACKGROUND: Right ventricular (RV) dysfunction is a major determinant of outcomes in patients with pulmonary arterial hypertension (PAH), although the optimal measure of RV function is poorly defined. We evaluated the utility of RV free-wall speckle tracking strain as an assessment tool for RV function in patients with PAH who are already under specific treatment compared with conventional echocardiographic parameters and investigated the relationship of RV free-wall strain with clinical hemodynamic parameters of RV performance...

BACKGROUND: In cases of chronic thromboembolic pulmonary hypertension (CTEPH), referral for possible surgical intervention is important because surgery can be curative. Surgery necessitates cardiopulmonary bypass and deep circulatory arrest with pulmonary thrombectomy and bilateral endarterectomy (PTE). If surgery fails, lung transplant is the next best surgical option. Medical treatment is also an important adjunct. CASE REPORT: A 35-year-old female presented 3 months after a pulmonary embolus was found to be completely occluding her left pulmonary artery...

High mitral inflow early (E) velocity to tissue Doppler E' ratio (E/E') and an E to late diastolic filling velocity ratio (E/A) are used to evaluate left ventricular (LV) diastolic function and filling pressure, but the usefulness of combined assessment of E/E' and E/A is not fully understood. Methods: We retrospectively analyzed 1,266 patients who underwent echocardiography to assess cardiac function. Patients were grouped based on the values of E/E' (low E/E'<15, high E/E'≥15) and E/A (low E/A≤0...
