REVIEW
Ajay Kumar Jha, Neeti Makhija
Cor triatriatum is a rare congenital cardiac anomaly defined by an abnormal septation within the atrium (left or right) leading to inflow obstruction to the respective ventricles. It exists either in isolated classical form or may be associated with simple to complex congenital cardiac anomalies. Several anatomical variants exist even in the classical form, and therefore, it may require multimodal diagnostic modalities to characterize and differentiate for better percutaneous interventional or surgical planning...

RATIONALE: Calcific aortic stenosis (AS) is characterized by calcium deposition in valve leaflets. However, women present lower aortic valve calcification (AVC) loads than men for the same AS hemodynamic severity. OBJECTIVE: We thus aimed to assess sex-differences in aortic valve fibro-calcific remodelling. METHODS AND RESULTS: One hundred and twenty-five patients underwent Doppler-echocardiography and multidetector-computed-tomography within 3 months prior to aortic valve replacement...

BACKGROUND: With age, aortic valve cusps undergo varying degrees of sclerosis which, sometimes, can progress to calcific aortic valve stenosis (AVS). To perform a retrospective clinico-pathologic investigation in patients with calcific AVS. METHODS: We characterized and graded the structural remodeling in 236 aortic valves (200 tricuspid and 36 bicuspid) from patients with calcific AVS (148 males; average 72years); possible relationships between general/clinical/echocardiographic characteristics and the histopathologic changes were explored...

Although rheumatic heart disease is becoming uncommon in industrialized countries, its global burden is still significant. We report the case of a 70-year-old male with rheumatic heart disease, who underwent 4 previous heart valve replacement surgeries, and presented to our hospital with refractory heart failure (NYHA functional class IV) due to severe stenosis of a previously implanted tricuspid bioprosthesis. The Heart Team deemed the patient as inoperable/high-risk for surgery. As an alternative, a transcatheter tricuspid valve-in-valve replacement was decided upon and later executed through the right femoral vein, with the insertion of an Edwards SAPIEN XT 29 no...

OBJECTIVES: The complexity of aortic disease is not fully exposed by aortic dimensions alone, and morbidity or mortality can occur before intervention thresholds are met. Patient-specific computational fluid dynamics (CFD) were used to assess the effect of different aortic valve morphologies on velocity profiles, flow patterns, helicity, wall shear stress (WSS), and oscillatory shear index (OSI) in the thoracic aorta. METHODS: A total of 45 subjects were divided into 5 groups: volunteers, aortic regurgitation-tricuspid aortic valve (AR-TAV), aortic stenosis-tricuspid aortic valve (AS-TAV), aortic stenosis-bicuspid aortic valve right-left cusp fusion (BAV[RL]), and aortic stenosis-right-non cusp fusion (AS-BAV[RN])...

OBJECTIVES: Describe changes in measures of right ventricular (RV) function in patients treated for aortic stenosis using open-chest surgery (SAVR) or transcatheter treatment (TAVR). METHODS: Patients in the Nordic Aortic Valve Intervention (NOTION) trial were randomized 1:1 to TAVR (n = 114) or SAVR (n = 106). Echocardiography was performed at baseline and 3 and 12 months post-procedure. Tricuspid annular plane systolic excursion (TAPSE) and right ventricular fractional area change (RVFAC) were used as measures of longitudinal and transverse RV contraction...

A heart with two atriums but one ventricle, an anatomy with a unique physiology, is responsible for many creative surgical and interventional approaches in history. Different surgical techniques have been used to address this strange physiology of parallel circulation. All these attempts met with failure till the concept of Fontan circulation was described. Currently, controversy exists between multistage vs. single stage total cavopulmonary connections. Total cavopulmonary connection is the only definitive procedure performed to provide palliation for patients with complex congenital heart defects which cannot support a biventricular circulation...

OBJECTIVE: The need for biological markers of aortic wall stress and risk of rupture or dissection of ascending aortic aneurysms is obvious. To date, wall stress cannot be related to a certain biological marker. We analyzed aortic tissue and serum for the presence of different MMP-2 isoforms to find a connection between serum and tissue MMP-2 and to evaluate the potential of different MMP-2 isoforms as markers of high wall stress. METHODS: Serum and aortic tissue from n = 24 patients and serum from n = 19 healthy controls was analyzed by ELISA and gelatin zymography...

There are limited data showing right ventricular preload increase due to high-flow arteriovenous fistulas (AVFs). This cross-sectional study investigated whether high AVF flow had an impact on right ventricular function in patients undergoing hemodialysis. Sixty-four patients aged between 18 and 85 years who were on routine hemodialysis with >2 hemodialysis sessions per week for at least 3 months via an AVF were studied. Patients with inadequate flow fistulas, severe chronic obstructive pulmonary disease, history of pulmonary embolism, primary pulmonary hypertension, severe mitral, aortic or pulmonary regurgitation, and/or stenosis were excluded...

Temporary tricuspid valve detachment improves the operative view of certain congenital ventricular septal defects (VSDs), but its long-term effects on tricuspid valve function are still debated. From 2002 through 2012, we performed a prospective study of 68 children (mean age, 1.28 ± 1.01 yr) who underwent transatrial closure of VSDs following temporary tricuspid valve detachment. Sixty patients had conoventricular and 8 had mid-muscular VSDs. All were in sinus rhythm. Seventeen patients had systemic pulmonary artery pressures...

Parachute valve is the malformation of an atrioventricular valve in which the tension apparatus springs from a single papillary muscle or group of muscles. Parachute tricuspid valve is a rare anomaly with no surgically repaired case to date. We describe a case of parachute deformity of the tricuspid valve leading to hemodynamically significant severe tricuspid stenosis. The present case was successfully repaired surgically along with atrial septal defect (ASD) and ventricular septal defect (VSD) closure.

BACKGROUND: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) may coexist with aortic stenosis. The aim of this study was to assess the association between RV dysfunction, TR, associated comorbidities, and outcomes following transcatheter aortic valve replacement (TAVR). METHODS: A retrospective analysis was conducted of baseline and 6-month clinical and echocardiographic parameters, including TR grade, RV size (grade, end-diastolic and end-systolic areas, annular diameter), and function (grade, tricuspid annular plane systolic excursion [TAPSE], fractional area change, Tei index), in 519 consecutive TAVR patients...

OBJECTIVES: To assess the natural history and outcome of fetal pulmonary stenosis [PS] detected at 14 to 16 weeks gestation. METHODS: This is a retrospective study, in the years 2004-2015, with serial follow up during pregnancy. Patients referred for complete early fetal ultrasound including all fetal systems and a fetal echocardiogram. Ninety seven percent of the women were low risk, and 3% had risk factors such as maternal type 1 diabetes mellitus, exposure to teratogenic drugs or anomalies in previous pregnancies or in other family members...

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

The association of tricuspid atresia with aortopulmonary window is exceptionally rare. We report a patient with tricuspid atresia, normally related great arteries, non-restrictive ventricular septal defect, and no pulmonary stenosis (type IC) with an aortopulmonary window who underwent successful initial surgical palliation. The unique anatomical feature of this case, other than the presence of the aortopulmonary window, was the absence of pulmonary stenosis at the level of either the ventricular septal defect or the pulmonary valve...

A 76 year-old woman was admitted to the Emergency Department for recent-onset dyspnea and cough. The electrocardiogram was considered inconclusive. A thoracic X-ray showed global cardiac profile enlargement. Computed tomography, acutely performed in the clinical suspicion of atypical pneumonia/myocarditis or pericardial effusion, showed cardiac enlargement especially of the right chambers. In order to investigate Ebstein's anomaly, pericardial cysts, tumors or other conditions of the right heart a simple trans-thoracic echocardiogram was performed...
