Pulmonary hypertension is associated with increased mortality and morbidity in the elderly population. Heart failure is a common cause of pulmonary hypertension. Yet, the relation between left heart parameters reflective of subclinical cardiac dysfunction and increased filling pressures, and pulmonary arterial pressures in the elderly population remains elusive. Within the population-based Rotterdam Study, 2592 unselected participants with a mean age of 72.6 years (61.4% women) had complete echocardiography data available...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is widely applied for the treatment of severe aortic stenosis (AS) in developed countries; however, in China, it is still in the early stage of utilization. On the basis of previous studies, this work explored the feasibility of TAVR in patients with severe AS in China and analyzed the cause of death in four cases. METHODS: This retrospective study included 20 patients who had severe AS and underwent TAVR with a balloon-expandable system (Edwards SAPIEN XT) in our hospital from January 2011 to June 2016...

Cryopreservation can be used for long-term preservation of tissues and organs. It relies on using complex mixtures of cryoprotective agents (CPAs) to reduce the damaging effects of freezing, but care should be taken to avoid toxic effects of CPAs themselves. In order to rationally design cryopreservation strategies for tissues, it is important to precisely determine permeation kinetics of the protectants that are used to ensure maximum permeation, while minimizing the exposure time and toxicity effects. This is particularly challenging with protectant solutions consisting of multiple components each with different physical properties and diffusing at a different rate...

AIMS: Leaflet thrombosis (LT) has become increasingly recognised following transcatheter and surgical aortic ABV replacement and can be reliably identified by MDCT. However, it is ongoing debate whether MDCT-defined LT is associated with adverse cerebrovascular outcomes. We performed a systematic review and meta-analysis to assess the incidence and clinical outcomes associated with multidetector computed tomography (MDCT)-defined leaflet thrombosis following aortic bioprosthetic valve (ABV) replacement...

Approximately one-third of patients with infective endocarditis require surgical treatment, but the ideal procedure that prevents infection ensures long durability and maintains quality of life remains unclear. A 21-year-old man who was diagnosed with aortic active infective endocarditis was referred to our hospital for surgical treatment. Echocardiography showed bicuspid aortic valve, severe aortic regurgitation, a large vegetation, and a paravalvular abscess. We planned to perform elective surgical treatment after antibiotic therapy; however, progression to heart failure required urgent operation...

OBJECTIVES: Multidetector CT (MDCT) is a valuable tool for functional prosthetic heart valve (PHV) assessment. However, radiation exposure remains a concern. We assessed a novel CT-acquisition protocol for comprehensive PHV evaluation at limited dose. METHODS: Patients with a PHV were scanned using a third-generation dual-source CT scanner (DSCT) and iterative reconstruction technique (IR). Three acquisitions were obtained: a non-enhanced scan; a contrast-enhanced, ECG-triggered, arterial CT angiography (CTA) scan with reconstructions at each 5 % of the R-R interval; and a delayed high-pitch CTA of the entire chest...

Background: Visceral arterial pseudoaneurysms (VAPAs) are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication. Report: An 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications...

Extensive mitral annulus calcifications are considered a contraindication for valve surgery. We describe the case of a 76-year-old female with severe mitral and aortic stenosis associated with extensive calcifications of the heart. The patient underwent an open mitroaortic valve replacement using transcatheter aortic valve implantation with an Edwards SAPIEN XT valve (Edwards Lifesciences Corp., Irvine, CA, USA) in the mitral position. The aortic valve was replaced using a stentless valve prosthesis (LivaNova SOLO; LivaNova PLC, London, UK)...

Purpose: To present a new surgical technique 'Scleral Sleeve Method' which would reduce the risk of Ahmed Glaucoma Valve (AGV) tube related complications in patients undergoing AGV FP7 (New World Medical Inc., Rancho Cucamonga, CA) for refractory glaucoma. Design: Prospective, Non-Randomized, hospital based interventional case series. Subjects: A total of 16 eyes of adult patients (10 males and 6 females) with refractory glaucoma. Methods: Instead of using sutures to fix the AGV tube to sclera, we devised a novel method of intra-scleral tube fixation by creating a scleral tunnel fashioned in form of sleeve...

We present a 73 years old woman who presented with pelvic cancer, ongoing sepsis and presumably a new diastolic murmur. Her transthoracic echocardiogram, as part of a sepsis screen, showed an abnormal pulmonary valve with moderate regurgitation. Trans-oesophageal echocardiography using 3D imaging showed a bicuspid pulmonary valve as the cause for the moderate regurgitation, but with no clear source of infection. Bicuspid pulmonary valve as an isolated clinical entity is a rare finding in clinical practice. Bicuspid pulmonary valves tend to be more commonly associated with other congenital cardiac anomalies...

BACKGROUND: Surgical treatment of active prosthetic aortic valve endocarditis presents a challenge for cardiac surgeons because of tissue friability and destruction caused by infection. Sutureless prostheses, such as the Perceval S® (LivaNova, Saluggia, Italy), have emerged as an option among the different surgical approaches for these complicated cases. METHODS: This study presents data from nine patients who underwent aortic valve re-replacement with the Perceval S® due to active prosthetic aortic valve endocarditis, between January 2014 and August 2016...

BACKGROUND: Annulus-sparing (AS) repair of tetralogy of Fallot (TOF) carries a potential increased risk reoperation for re-stenosis and unproven benefits on right ventricular (RV) geometry. METHODS: Primary TOF repairs (N=434) between 2000 and 2012 were studied using risk-adjusted parametric techniques. Progression of cardiac dimensions were analyzed using repeated measures regression using reports of all 2,103 echocardiograms undertaken throughout the study period, to maximum follow-up 13...

We report the case of a 4-year-old boy with Ehlers-Danlos syndrome undergoing single-ventricle palliation for an unbalanced atrioventricular canal defect. No reports of single-ventricle palliation in the setting of connective tissue disorders exist in the current literature. Unique findings on the patient's preoperative imaging included a disproportionately large neoaortic root and a regurgitant atrioventricular valve, which may foretell the need for future intervention.

We report the case of a female neonate born at 40 weeks' gestation with no known risk factors. On postnatal day 27, she was transferred to the pediatric intensive care unit and intubated for cardiorespiratory failure; she was diagnosed with group B streptococcus infective endocarditis. Mitral valve vegetations did not improve with antibiotic therapy. Mitral valve surgery was performed on postnatal day 36. A mechanical mitral valve with short-segment polytetrafluoroethylene skirt was inserted into the supra-annular position; gentian violet was applied to the sewing ring and skirt...

Repeat mitral valve replacement in patients who underwent mechanical replacement during infancy may be technically very difficult due to the small-sized annulus accommodating the prosthesis. That can lead to dense fibrosis of the small annulus onto the sewing cuff. An attempt at explanting the prosthesis carries high risk of circumflex coronary artery injury or atrioventricular junction disruption. We present a novel approach to prevent a disaster in such a difficult scenario-implanting the new prosthesis above the previous prosthetic housing after removing the prosthetic leaflets...
