BACKGROUND: Trans-catheter mitral valve replacement (TMVR) procedures had emerged as an alternative solution for patients who are at high risk for mitral valve surgery. Although cardiac computed tomography (CT) remains the standard method for procedural planning, there is no full agreement on the best systolic phase for quantitation of the neoLVOT. Furthermore, a new three-dimensional trans-esophageal echocardiography (3DTEE) based software was developed to serve as filter and or an alternative for patients who cannot have CT due to any contraindication...

Patients with many forms of congenital heart disease (CHD) and hypertrophic cardiomyopathy undergo surgical intervention to relieve left ventricular outflow tract obstruction (LVOTO). Cardiovascular Computed Tomography (CCT) defines the complex pathway from the ventricle to the outflow tract and can be visualized in 2D, 3D, and 4D (3D in motion) to help define the mechanism and physiologic significance of obstruction. Advanced cardiac visualization may aid in surgical planning to relieve obstruction in the left ventricular outflow tract, aortic or neo-aortic valve and the supravalvular space...

BACKGROUND: Echocardiographic grading of mitral regurgitation (MR) in mitral valve prolapse (MVP) is challenging. 3D vena contracta area (3D VCA) has been proposed as valuable method. However, data defining the cut-off values of severity and validation in the subset of patients with MVP are scarce. The aim of this study was to validate the 3D VCA by 3D transesophageal color-Doppler echocardiography (3D-TEE) in patients with MVP and to define the cut-off values of severity grading. The secondary aim was to compare 3D VCA to the EROA-PISA method...

Midventricular hypertrophic obstructive cardiomyopathy (HOCM) is characterized by hypertrophy of the interventricular septum (IVS) and - in rare cases - of the papillary muscles (PM), which subsequently can cause dynamic left ventricular outflow tract obstruction (LVOTO) and severe heart failure symptoms. We report on a rare case of a 44-year-old patient suffering from midventricular HOCM with hypertrophic anterolateral PM and an additional chorda between the PM and the IVS.We describe a new surgical approach via right anterolateral thoracotomy in 3-dimensional (3D) video-assisted minimal-invasive technique with resection of hypertrophic PMs as well as the entire mitral valve-apparatus and valve replacement avoiding septal myectomy and potentially associated complications...

BACKGROUND: Accurate assessment of flow status is crucial in low-gradient aortic stenosis (AS). However, the clinical implication of three-dimensional transesophageal echocardiography (3DTEE) on flow status evaluation remains unclear. This study aimed to investigate the assessment of flow status using 3D TEE in low-gradient AS patients.

Left ventricular outflow tract (LVOT) obstruction is a common and life-threatening complication of transcatheter mitral valve replacement (TMVR). The laceration of the anterior mitral leaflet to prevent outflow obstruction (LAMPOON) is a novel technique involving anterior mitral leaflet split after valve-in-ring TMVR (1). Three-dimensional (3D) printing has emerged as a powerful tool in diagnosing and planning complex percutaneous interventions (2). We report for the first time a tip-to-base LAMPOON after transcatheter mitral valve-in-ring replacement, guided by 3D-printed anatomical models...

This study aimed to evaluate the anatomical reproducibility of a preoperative intracardiac 3D image (IC image) created using computed tomography, and to investigate its usefulness as a surgical decision-making tool. Between 2012 and 2022, ventricular septal defect (VSD) patients, and double outlet right ventricle (DORV) or transposition of the great arteries (TGA) with pulmonary stenosis (PS) patients who underwent cardiac surgery and had preoperative computed tomography were enrolled. SYNAPSE VINCENT® (Fujifilm) was used to create an IC image which was analyzed retrospectively...

Disconnected branch pulmonary arteries are sparsely reported cases in prenatal diagnosis literature. We report a case of tetralogy of Fallot with disconnected branch pulmonary arteries, the left pulmonary artery (LPA) arising from an indirect ductus arteriosus (DA) from the base of the innominate artery in a right aortic arch, diagnosed by fetal echocardiography with 3D/4D spatiotemporal image correlation (STIC) imaging. Prenatal diagnosis led to early neonatal intervention to maintain blood flow to the LPA by stenting of the DA...

Nowadays, the diagnosis of cardiac myxomas (CM), particularly the histological types, remains a challenge. Two-dimensional (2D) transthoracic (TT) and transesophageal (TEE)  echocardiography (ECHO) represent the first steps in the imaging pathway. 3D ECHO,  implemented in imaging practice, appears to be an emerging diagnostic technique that overcomes some of the limitations of 2D ECHO while integrating the information provided by magnetic resonance (MRI). However, its role in the imaging arena is still debatable...

Dextrocardia is a rare congenital malformation in humans in which most of the heart mass is positioned in the right hemithorax rather than on the left. The heart itself may be normal and dextrocardia is sometimes diagnosed during non-related explorations. A few reports have documented atypical positions of the cardiac chambers in farmed teleost fish. Here, we report the casual finding of a left-right mirrored heart in an 85 cm long wild-caught spiny dogfish (Squalus acanthias) with several organ malformations...

BACKGROUND: Diagnosing severe aortic stenosis (AS) depends on flow and pressure conditions. It is suspected that concomitant aortic regurgitation (AR) has an impact on the assessment of AS severity. The aim of this study was to analyze the impact of concomitant AR on Doppler-derived guideline criteria. We hypothesized that both transvalvular flow velocity (maxVAV ) and the mean pressure gradient (mPGAV ) will be affected by AR, whereas the effective orifice area (EOA) and the ratio between maximum velocity of the left ventricular outflow tract and transvalvular flow velocity (maxVLVOT /maxVAV ) will not...

BACKGROUND: Radiofrequency catheter ablation is the preferred treatment choice for ventricular arrhythmias (VAs) originating from right ventricular outflow tract (RVOT) in symptomatic patients and is usually performed under fluoroscopy guidance. Zero-fluoroscopy (ZF) ablations using 3D mapping system applied for treatment of various types of arrhythmias are trending and practiced in many centers around the world, but rarely done in Vietnam. The objective of this study was to evaluate the efficacy and safety of zero-fluoroscopy ablation of RVOT VAs, compared with fluoroscopy-guided ablation without a 3D electroanatomic mapping (EAM) system...
