BACKGROUND: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare condition that can be difficult to diagnose by echocardiography alone. The purpose of this study was to describe the clinical and echocardiographic presentation of ALCAPA, create a set of critical echocardiographic diagnostic criteria, and report outcomes. METHODS: A retrospective review was conducted of all patients diagnosed with isolated ALCAPA at two major cardiac centers between 1990 and 2015...

BACKGROUND: Pulmonary artery (PA) aneurysms are rare and have been reported only in case reports or small series. We reviewed our experience with surgical repair of PA aneurysms. METHODS: We reviewed all patients with a true PA aneurysm undergoing cardiac operations between 1995 and 2015. We excluded aneurysms and pseudoaneurysms related to right ventricular outflow tract patches or previous conduits. RESULTS: There were 38 patients (24 women [63%]; mean age, 46 ± 15 years), and 14 patients (37%) were asymptomatic...

Paravalvular leaks are common following valve replacement surgery. Majority are benign and do not require any active intervention. However, occasionally severe paravalvular regurgitation can produce heart failure and/or hemolysis, needing closure of the defect. It is more commonly associated with aortic and mitral prosthesis, symptomatic tricuspid paravalvular regurgitation being a rare entity. In this report we present the successful percutaneous transcatheter closure of a large paravalvular tricuspid regurgitation in a 59-year old lady with history of multiple previous operations...

An 86-year-old man underwent cataract surgery on the left eye, but suddenly he lost his vision three days after surgery. Topical treatments for panophthalmitis were started according to international guidelines. Later, a broad-range polymerase chain reaction showed Enterococcus faecalis in corpus vitreum, and IV antiobiotic treatment was initiated. To exclude endocarditis an echocardiography was performed, and this showed mitral regurgitation with a small mobile vegetation. Uncertainty concerning a possible causality between panophthalmitis and mitral valve endocarditis remains...

OBJECTIVE: Although aortic valve-sparing operations are performed throughout Japan, the indications, specific repair techniques, and outcomes have not been reported in full. Thus, we conducted the first nationwide survey of aortic valve-sparing surgery. METHODS: We mailed a questionnaire to 508 institutions across Japan to obtain information on elective aortic valve and aortic root surgeries performed in 2014. Included in the mailing was a secondary questionnaire that sought further information from institutions reporting aortic valve-sparing surgeries...

Tricuspid valve disease is a frequent condition but is currently undertreated. A limited number of patients undergo an isolated surgical tricuspid repair, and this intervention is associated with poor outcomes, especially in patients with previous cardiac surgery. Most patients are only medically treated, despite the impact of severe tricuspid regurgitation on functional status and long-term survival. Transcatheter therapies represent a promising alternative for patients with severe tricuspid regurgitation and high surgical risk...

Transcatheter edge-to-edge mitral valve repair (TMVr) with MitraClip has proved to be safe and effective for high-risk surgical patients with severe symptomatic degenerative mitral regurgitation. There is paucity of data regarding its use in functional mitral regurgitation (FMR). The objective of this study was to evaluate the use of MitraClip in patients with symptomatic moderate or severe FMR and a high surgical risk. Medical libraries were systematically searched for studies assessing the use of MitraClip for patients with symptomatic moderate or severe FMR and a high surgical risk...

Defibrillation can be successfully provided by the subcutaneous implantable cardioverter defibrillator (ICD) without the leads. In contrast, traditional ICDs require leads that can cause central venous stenosis, lead-induced endocarditis, and carry the risk of tricuspid regurgitation by valve adhesion, perforation, coaptation interference, or entanglement. Central venous stenosis, infection, and tricuspid regurgitation are all critically important considerations in hemodialysis patients. Recent reports are supporting the use of subcutaneous ICDs in renal patients maintained on long-term hemodialysis...

BACKGROUND: Balloon dilatation of a bioprosthetic valve in the pulmonary position could be performed to delay valve replacement. We proposed to identify the long-term effectiveness of such a procedure. METHODS: We reviewed the medical records of 49 patients who underwent balloon valvuloplasty between January 2000 and December 2015. The primary goal was to determine the time interval until the following surgical or catheter intervention. RESULTS: The mean age at bioprosthetic valve insertion was 5...

The left ventricular (LV) remodeling process associated with significant valvular heart disease (VHD) is characterized by an increase of myocardial interstitial space with deposition of collagen and loss of myofibers. These changes occur before LV systolic function deteriorates or the patient develops symptoms. Cardiovascular magnetic resonance (CMR) permits assessment of reactive fibrosis, with the use of T1 mapping techniques, and replacement fibrosis, with the use of late gadolinium contrast enhancement...

The global impact of the spectrum of valve diseases is a crucial, fast-growing, and underrecognized health problem. The most prevalent valve diseases, requiring surgical intervention, are represented by calcific and degenerative processes occurring in heart valves, in particular, aortic and mitral valve. Due to the increasing elderly population, these pathologies will gain weight in the global health burden. The two most common valve diseases are aortic valve stenosis (AVS) and mitral valve regurgitation (MR)...

PURPOSE OF REVIEW: Imaging is essential for the management of adults with repaired tetralogy of Fallot (rToF). Echocardiography and cardiac magnetic resonance imaging are the central modalities to assess rToF. Here we review recent literature on imaging rToF, focusing on echocardiography and advances in assessment of cardiac mechanics. RECENT FINDINGS: Several two-dimensional, three-dimensional, and Doppler echo parameters have been proposed to assess pulmonary regurgitation, right ventricular volumes and ejection fraction, but most of them still have important limitations in their feasibility and reliability compared to cardiac magnetic resonance (CMR)...
