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...

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...

OBJECTIVE: Adoption of robotic mitral valve surgery has been slow, likely in part because of its perceived technical complexity and a poorly understood learning curve. We sought to correlate changes in technical performance and outcome with surgeon experience in the "learning curve" part of our series. METHODS: From 2006 to 2011, two surgeons undertook robotically assisted mitral valve repair in 458 patients (intent-to-treat); 404 procedures were completed entirely robotically (as-treated)...

REVIEW
Erin A Fender, Chad J Zack, Rick A Nishimura
Isolated tricuspid regurgitation (TR) can be caused by primary valvular abnormalities such as flail leaflet or secondary annular dilation as is seen in atrial fibrillation, pulmonary hypertension and left heart disease. There is an increasing recognition of a subgroup of patients with isolated TR in the absence of other associated cardiac abnormalities. Left untreated isolated TR significantly worsens survival. Stand-alone surgery for isolated TR is rarely performed due to an average operative mortality of 8%-10% and a paucity of data demonstrating improved survival...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has greatly expanded the treatment options available for patients with severe aortic stenosis at high surgical risk. MATERIALS AND METHODS: We compared changes in myocardial function in TAVR with a transfemoral (TF) versus a transapical (TA) approach at a major tertiary hospital from 2012-2016. Traditional echocardiographic measures of cardiac structure and function were tracked, alongside the use of two-dimensional speckle tracking echocardiography to measure myocardial strain and strain rates...

OBJECTIVES: Tricuspid valve repair (TVr) has both a theoretical advantage in preserving right ventricular function and disadvantages such as a higher risk of repair failure in the long-term compared with tricuspid valve replacement (TVR). This study was conducted to compare the results of TVr with those of TVR to find an optimal treatment option. METHODS: A literature search of 5 databases was performed. The primary outcome was all-cause mortality. Secondary outcomes were tricuspid reoperation and valve-related events...

Myocardial contusion and aortic injury are well-known cardiac complications of blunt chest trauma, but valvular injury is rare. Traumatic valve injuries most commonly involve the aortic valve, with isolated mitral valve injury being quite rare. We report a case of acute severe mitral regurgitation due to ruptured chordae tendineae requiring surgical repair following a motor vehicle accident.

Symptomatic aortic stenosis can be treated by surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR), the latter of which is regarded as a minimally invasive procedure. Differences between these procedures regarding immune responses or changes in coagulation and neurocognitive function have thus far been evaluated only sparsely. We carried out a prospective, single-center, nonrandomized explorative study with 38 patients. Thirteen patients were subjected to either SAVR or transfemoral (TF-) TAVR, and 12 patients underwent transapical (TA-) TAVR...
