Left ventricular outflow tract obstruction is a well-known, albeit rare, adverse event that can occur after mitral valve replacement. With the current increase in transcatheter valve interventions, new and unique adverse events may be expected to occur. We present a case of severe left ventricular outflow tract obstruction that developed after transcatheter mitral valve implantation.

Mitral annular calcification (MAC) is a chronic degenerative process associated with advanced age and conditions predisposing to left ventricular hypertrophy. Assessment of mitral valve disease in patients with severe MAC can be a challenge. When severe MAC results in mitral stenosis or regurgitation, multimodality imaging with 2-dimensional, 3-dimensional, and Doppler echocardiography and cardiac computed tomography angiography can delineate the severity and pathoanatomic features to help guide therapeutic strategies...

BACKGROUND: Sutureless self-expandable aortic bioprostheses rely on radial forces for stabilization, raising concern that these devices may increase the risk of postoperative conduction disease. The purpose of this study was to determine the incidence of conduction disorders after sutureless aortic valve replacement (AVR) with the Perceval S (Sorin Group, Saluggia, Italy) bioprosthesis. METHODS: Between June 2011 and March 2013, 108 consecutive patients underwent sutureless AVR with the Perceval S prosthesis...

Until now, to our knowledge no case of bioprosthetic valvular thrombosis after implantation of the sutureless Sorin Perceval valve has been reported. Although sutureless aortic valve replacement has become a powerful tool in our daily practice, recent guidelines from the European Society of Cardiology, the European Association for Cardio-Thoracic Surgery, the American College of Cardiology, and the American Heart Association do not give specific recommendations on postoperative anticoagulation therapy. We report the first case of valve dysfunction resulting from thrombosis 12 months after implantation with a possible link to postoperative cortisole therapy...

Totally endoscopic cardiac operations for coronary procedures and atrial septal defect repair have demonstrated improved quality of life, but they have required longer cross-clamp times compared with open operations. Although transcatheter valve implantation remains appropriate for inoperable patients, the totally endoscopic approach could be an effective treatment for lower risk patients, including complete removal of the stenotic aortic valve, while minimizing surgical chest wall trauma, and providing excellent early quality of life...

Thrombocytopenia occurring after surgical bioprosthetic valve implantation is a phenomenon that has been long investigated, and various explanations have been provided [Santarpino 2012a]. Our group has been addressing this topic over several years, extending back to the original description of this phenomenon in Freedom Solo (Sorin Group, Saluggia, Italy). However, we observed that this was a transitory and self-limited phenomenon without clinical consequence [Santarpino 2011; Santarpino 2012a]. Our center began implanting the Perceval aortic valve (Sorin Group, Saluggia, Italy) in 2010, and we have gained a vast experience in sutureless aortic valve replacement with Perceval, with more than 300 implants performed to date [Fischlein 2015]...

BACKGROUND: In patients with frequent premature ventricular contractions (PVCs), little is known about the profile of PVCs and the outcome of treatment in patients with mitral valve prolapse (MVP) compared to those without MVP. METHODS AND RESULTS: Patients with documented PVCs between January 2001 and October 2012 were divided into 2 groups: MVP and non-MVP. The PVC characteristics, efficacy of therapy, and outcome were compared between the 2 groups. A total of 112 patients with MVP and 952 without MVP were identified...

Objective Endovascular valve in stented biological valve implantation (valve-in-valve transcatheter aortic valve implantation [TAVI ViV]) is increasingly becoming a valid option for bioprosthesis degeneration. TAVI implantation in small stented biological valves below 23 mm is controversially discussed. Reduced opening area and high gradients are typical objections against this procedure in cases of small bioprosthesis. Systematic studies about the hemodynamic performance of endovascular valves in small stented bioprosthesis, however, do not exist...

INTRODUCTION: This article reflects on the plight of patients with short bowel syndrome (SBS) in developing countries. SBS is life threatening, rare, complex and often not considered a priority by healthcare planners in the developing countries because of the high cost of treatment. Data was collected and analyzed from 3 different hospitals in two different countries (Romania and Austria) from November 2013 to February 2016 CASE PRESENTATION: The patient had an emergency surgery for volvulus as a result of an extensive ischemic necrosis, with just 80cm of the bowel left and no ileocecal valve after enterectomy...

BACKGROUND: The impact of pre-procedural RV size and function on outcomes following transcatheter aortic valve replacement (TAVR) is not well established. The aim of this study was to investigate the role of right ventricular size and function on outcomes following TAVR. METHODS AND RESULTS: Between November 2008 and June 2013, 268 consecutive patients (age 80.5±7.9years, aortic valve area 0.79±0.16cm(2)) with symptomatic severe aortic stenosis (AS) undergoing TAVR at Mayo Clinic were included...

OBJECTIVES: We examined the Sorin Perceval S artificial biological valve implantation techniques, and present the initial experiences in our unit. METHODS: In the last 1.5 years, 27 patients had been implanted with Sorin Perceval S biological arteficial valve due to aortic valve disease. The device was mainly used in high-risk patients, in reoperative circumstances, in cases of calcified aortic root, and in elderly patients. RESULTS: The valve implantation time, aortic cross clamp time is shorter, but the risk of the operation cannot be eliminated entirely, because of the high risk patients' severe comorbidities...

BACKGROUND: In elderly high-risk surgical patients, sutureless aortic valve replacement (AVR) should be an alternative to standard AVR. The potential advantages of sutureless aortic prostheses include reducing cross-clamping and cardiopulmonary bypass (CPB) time and facilitating minimally invasive surgery and complex cardiac interventions, while maintaining satisfactory hemodynamic outcomes and low rates of paravalvular leakage. The current study reports our single-center experience regarding the early outcomes of sutureless aortic valve implantation...

Aortic root replacement with porcine xenograft is a valuable treatment option in acute aortic dissection, but conduits are often prone to degeneration. Reoperation is still associated with high operative mortality, and it usually requires root removal and repetition of the Bentall procedure, or a less radical option limited to valve replacement. We describe two cases of Freestyle root degeneration in patients with chronic aortic dissection, in whom we performed a valve-in-valve procedure with the Perceval S prosthesis (Sorin Group, Saluggia, Italy)...
