Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology...

Intermittent dysfunction of mechanical mitral valve prosthesis is an uncommon condition. It carries serious clinical implications if unrecognized. Here, we present a case of a 28-year-old female with a history of rheumatic multivalvular disease, for which she had undergone double valve replacement and tricuspid annuloplasty. Six months later, she presented with heart failure. Clinical examination revealed intermittent loss of closing clicks followed by a pansystolic murmur at the apex, suggestive of mitral prosthetic valve dysfunction...

Purpose: The placement of a pulmonary artery catheter sometimes needs long time by observing the pressure wave, and several factors have been reported to hinder the placement. In the present study, we examined whether enlargement of the aortic root is associated with longer time for the placement. Method: We examined the time required for the catheter placement. The catheter placement time was defined as the duration of time required for the catheter to float from the CVP position to the pulmonary artery...

There is controversy about handling functional mitral regurgitation in patients undergoing aortic valve or proximal aortic operations. We describe a transaortic Alfieri edge-to-edge repair for functional mitral regurgitation that reduces operative excessive invasion and prolonged cardiopulmonary bypass time. Between May 2013 and December 2016, 10 patients underwent transaortic Alfieri edge-to-edge mitral repair. There were no operative deaths. The severity of mitral regurgitation immediately after the operation by transesophageal echocardiography was none or trivial in all patients...

Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction...

Sutureless aortic valves are increasingly used for aortic valve replacement (AVR) with excellent outcomes. Implantation requires device expansion in a subannular position within the native aortic root. We report a patient with severe aortic stenosis who received a Perceval sutureless AVR (LivaNova, London, United Kingdom), resulting in a competent prosthesis with an absence of paravalvular leak and aortic regurgitation. However, this implantation resulted in the exacerbation of mitral regurgitation. The sutureless valve required explantation, and a traditional sutured valve was subsequently implanted, which returned the mitral regurgitation to baseline...

The optimal timing for pulmonary valve replacement after Tetralogy of Fallot (TOF) repair remains controversial. In this study, we estimated the feasibility of using flow energy loss (FEL) to predict right ventricular (RV) deterioration due to pulmonary regurgitation after TOF repair. We examined RV outflow tract (RVOT) flow in nine patients who underwent TOF or double-outlet right ventricle repair in the intervention group (Group I) and compared them with three healthy children in the control group (Group C)...

BACKGROUND: Intrinsic abnormalities of the mitral valve are common in patients with hypertrophic cardiomyopathy and may need to be addressed at operation. METHODS: Consecutive patients undergoing transmitral septal myectomy were retrospectively reviewed. The ventricular septum was exposed through a left atriotomy, and the anterior leaflet of the mitral valve was detached from its annulus. An extended myectomy was performed to the base of the papillary muscles. After myectomy, the anterior leaflet was reattached and concomitant mitral valve repair or replacement was performed...

OBJECTIVES: The association between the aortic root diameter and aortic regurgitation in hypertensive and normotensive people is still disputed, and the underlying mechanisms remain to be clearly elucidated. We aimed to investigate the relationship between the aortic root diameter and trivial to mild functional aortic regurgitation in never-treated hypertensive patients with a new diagnosis compared with healthy normotensive participants. METHODS: A total of 182 hypertensives and 232 age-matched normotensives were included in the study...

Case summary: Bronchial stents may be useful to relieve clinical signs of extraluminal compression. Herein we describe a case which, to our knowledge, is the first cat where bilateral bronchial stents have been used clinically. Respiratory signs of principal bronchial compression were alleviated after the stent procedure. Minor complications occurred, specifically: severe hypoxia during stent deployment; a transient, self-limiting postoperative pneumothorax possibly associated with ventilation-induced lung injury; bronchopneumonia (possibly pre-existing); and transient worsening of cough postoperatively...

BACKGROUND: In severe asymptomatic primary mitral valve regurgitation without risk factors, surgery strategy is controversial. We sought to clarify whether being symptomatic corresponds to the hemodynamic burden and reduced exercise capacity. A better understanding of this may contribute to optimize timing of surgery. METHODS AND RESULTS: Subjects with asymptomatic (New York Heart Association functional class I, n=29) or symptomatic (New York Heart Association functional class II and III, n=28) significant primary mitral valve regurgitation (effective regurgitant orifice, ≥0...

INTRODUCTION: Filamin A (FLNA) is located in Xq28, and encodes the actin binding protein, filamin A. A mutation in FLNA is the most common cause of periventricular nodular heterotopia (PVNH), but a clear phenotype-genotype correlation has not been established. Indeed, some patients with a FLNA mutation have recently been shown to additionally have Ehlers-Danlos-like collagenopathy or macrothrombocytopenia. In an attempt to establish a clearer correlation between clinical symptoms and genotype, we have investigated a phenotype that involves thrombocytopenia in a patient with a truncation of the FLNA gene...

Dilatation of aortic root may distort the tricuspid annulus. We experienced a case of chronic aortic dissection presented with tricuspid regurgitation. Chest computed tomography revealed an enlarged ascending aorta displacing the right heart. The patient successfully underwent replacement of the aorta and tricuspid annuloplasty with a prosthetic annulus.

Recently, implantable cardioverter-defibrillators (ICD) have become capable of monitoring intrathoracic impedance to detect an increased fluid volume and heart failure. Pregnancy is a well-known cause of an increased body fluid volume; however, it is not clear whether the measurement of intrathoracic impedance by ICD is clinically useful for precisely detecting heart failure in pregnant women. We herein report the case of a 39-year-old woman with an ICD that had been implanted after an event of ventricular fibrillation due to severe aortic regurgitation with a bicuspid aortic valve...

BACKGROUND: Transcatheter caval valve implantation is under evaluation as a treatment option for inoperable patients with severe tricuspid regurgitation (TR). The procedure involves the catheter-based implantation of bioprosthetic valves in the inferior vena cava and superior vena cava to treat symptoms associated with TR. This study is the first to evaluate the feasibility, safety, and efficacy of this interventional concept. METHODS AND RESULTS: Twenty-five patients (mean age, 73...
