OBJECTIVES: The tricuspid annular plane systolic excursion (TAPSE) is a validated measure of right ventricular function; however, the apical echocardiographic window varies and has limitations in intensive care unit (ICU) patients receiving mechanical ventilation or those with underlying disease and air entrapment. We aimed to evaluate the subcostal echocardiographic assessment of tricuspid annular kick (SEATAK) as an alternative to TAPSE in critically ill patients. METHODS: To measure SEATAK, we obtained the subcostal inferior vena cava view and used M-mode to measure excursion of the tricuspid annulus (kick)...

OBJECTIVE: Systemic lupus erythematosus (SLE) can present limitations to exercise capacity and quality of life (QoL) because of various clinical conditions, such as pulmonary disease or heart disease. Tissue Doppler echocardiography (TDE) offers the promise of an objective measurement to quantify regional and global ventricular function through the assessment of myocardial velocity data. This study aimed to assess the intensity of left ventricular (LV) and right ventricular (RV) systolic and diastolic dysfunction in SLE patients by means of TDE and cardiopulmonary exercise (CPX) testing to determine their impact on QoL...

AIMS: Transcatheter cryoablation is a well-established technique for the treatment of AV nodal reentry tachycardia (AVNRT) in children. Nevertheless, A-V nodal slow pathway conduction may recur after an acutely successful procedure. The aim of this study was to evaluate the long-term outcome of acutely successful AVNRT cryoablations in pediatric patients in case of focal cryolesion and in case of need for High Density Linear Lesion (HDLL) cryoablation due to focal failure. METHODS: ...

BACKGROUND: Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension. This may not represent either the axis or the extent of dynamism through the entire cardiac cycle. In this study, we used real-time 3D transesophageal echocardiography (TEE) to analyze geometric changes in multiple axes of the TA throughout the cardiac cycle in patients without right ventricular abnormalities...

BACKGROUND: The noninvasive evaluation of right ventricular function (RVF) in cardiovascular and pulmonary diseases remains a challenge. Internationally recommended echocardiographic parameters for the evaluation of RVF may not be applicable to China, because of the limited examination time per patient, the varying skill levels of ultrasonographers, inadequate allocation of professional specialties, and outdated instruments and equipment. METHODS: Sixty-two patients admitted for right heart failure and 52 healthy volunteers were included in the analysis...

BACKGROUND: Noncompaction cardiomyopathy (NCCM) is considered to be the result of an arrest in the normal myocardial embryogenesis. The histological, developmental, and electrophysiological explanation of ventricular arrhythmias in NCCM is still unknown. The aim of this study was to determine the origin of premature ventricular contractions (PVCs) in NCCM and to identify any predominant arrhythmic foci. METHODS: Retrospective data from our NCCM registry including 101 patients were analyzed...

Right ventricular (RV) dysfunction harbingers adverse prognosis in pulmonary arterial hypertension (PAH). Although conventional two-dimensional echocardiography (2DE) is limited for RV systolic function quantitation, RV strain can be a useful tool. The diagnostic and prognostic impact of 2DE speckle-tracking RV longitudinal strain was evaluated, including other 2DE systolic indexes, in a group of PAH patients without severe impairment of functional capacity, chronic pulmonary thromboembolism or left ventricular dysfunction...

Evidence suggests an association between left heart obstructive lesions and dilated coronary sinus (DCS), but this has not been studied in fetuses. A retrospective review of fetal echocardiograms (FE) over an 8-year period was conducted, and patients with DCS were identified and confirmed postnatally. There were 5840 FE performed on 4920 women during this period. Of 49 patients with DCS, 22 had normal intracardiac anatomy and 27 patients had congenital heart disease (CHD) yielding an incidence of 4.6 % in the presence of CHD (27/584)...

BACKGROUND Left ventricular assist devices (LVAD) are used to treat heart failure. Preoperative prediction of RV function after LVAD implantation is crucial. Correlations were found between preoperative echo and RV function after LVAD implantation. MATERIAL AND METHODS We retrospectively reviewed 23 male patients (8 ischemic, 15 nonischemic cardiomyopathy) with LVAD implantation (17 HeartWare, 6 HeartMate II) at the Silesian Center for Heart Diseases from 1 January 2013 to 28 October 2014. Preoperative TTE data of RV function included RVFAC (fractional area change), TAPSE (tricuspid annulus plane systolic excursion), RV diameter (RV4), and RV/LV (right/left ventricle) ratio...

BACKGROUND: Tricuspid valve regurgitation in reported in >20% of heart recipients. It severity has not only clinical impact, but it is also associated with increased mortality. Risk factors for developing tricuspid valve dysfunction include allograft rejection, donor/recipient pericardial cavity mismatch, preoperative transpulmonary gradient and vascular resistance, biatrial anastomosis technique, and biopsy-induced injury. Tricuspid valve annulus distention is reported to causative factor for most common type of tricuspid valve dysfunction after heart transplantation...

BACKGROUND: Ebstein anomaly (EA) and tricuspid valve dysplasia (TVD) are rare anomalies and data on outcomes after a fetal or neonatal EA/TVD diagnosis are conflicting. METHODS: To examine the outcome and identify markers predictive of mortality, we reviewed our single-centre experience from 2000-2014. Variables were analyzed separately for cases diagnosed in utero without pregnancy termination and for all live-born patients. RESULTS: Of 47 fetal cases, 8 (17%) died in utero and 10 (21%) as neonates...

Right ventricular (RV) size, shape and function are distinctly load-dependent and pulmonary load is an important determinant of RV function in patients with congestive heart failure (CHF) due to primary impaired left ventricular function and in those with pre-capillary pulmonary hypertension (PH). In a pressure overloaded RV, not only dilation and aggravation of tricuspid regurgitation, but also systolic dysfunction leading to RV failure (RVF) can occur already before the development of irreversible alterations in RV myocardial contractility...

OBJECTIVES: An untreated dilated aortic annulus is a major risk factor for failure of aortic valve-sparing operations or repair of either bicuspid or tricuspid valve. Aortic annuloplasty efficiently reduces the annulus and increases the coaptation height, thus protecting the repair. This study analyses long-term results of 232 consecutive patients operated on with a standardized and physiological approach to aortic valve repair according to each phenotype of the dystrophic ascending aorta...

Right ventricular (RV) dysfunction is known to be highly correlated with mortality and morbidity; nevertheless, imaging-based assessment of RV anatomy and physiology lags far behind that of the left ventricle. In this study, we advance RV imaging using cardiac magnetic resonance (CMR) to accomplish the following aims: (i) track the motion of six tricuspid annular (TA) sites using a semi-automatic tracking system; (ii) extract clinically important TA measurements-systolic velocity (Sm), early diastolic velocity (Em), late diastolic velocity (Am), and TA plane systolic excursion (TAPSE)-for each TA site and compare these CMR-derived measurements in healthy subjects vs...
