Waleed H Ezzat, Sara W Liu
Importance: Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support. Objective: To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits...

OBJECTIVE: Overdrainage in children is a long-term problem for shunted patients which might lead to chronic anatomical changes. In order to prevent these problems, valve exchange is performed on a regular basis in patients without hydrostatic units towards a valve with both an adjustable and a gravitational unit. The clinical outcome of these patients is reported in a retrospective study. METHODS: Between 2009 and 2014, the in-house database was analyzed for patients who received a valve exchange towards an adjustable differential pressure valve with gravitational unit...

INTRODUCTION: The Bentall procedure is a cardiac surgery involving graft replacement of the aortic valve, aortic root and ascending aorta. Graft infection after Bentall's procedure (BGI) is infrequent but severe, and often difficult to diagnose and treat. PATIENTS AND METHODS: A retrospective cohort study was performed using the Bordeaux endocarditis database of adult patients admitted to the Bordeaux University Medical Hospital for BGI between 2008 and 2014. Published case reports were identified in the literature...

Some patients with pulmonary valve stenosis do not respond to balloon valvuloplasty and must undergo surgical repair. We report the case of a 12-year-old child with pulmonary valve stenosis and Noonan syndrome in whom we performed transcatheter Melody pulmonary valve implantation after balloon dilation failed. The result was excellent. This technique can be proposed as an alternative to surgery in such cases.

BACKGROUND: Aortic valve stenosis is a common finding diagnosed with high sensitivity in transthoracic echocardiography, but the examiner often finds himself confronted with uncertain results in patients with moderate pressure gradients and concomitant systolic heart failure. While patients with true-severe low-gradient aortic valve stenosis with either reduced or preserved left ventricular systolic function are primarily candidates for valve replacement, there is a relevant proportion of patients with pseudo-severe aortic valve stenosis anticipated not to benefit but actually rather deteriorate by interventional therapy or surgery...

BACKGROUND: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. METHODS: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014)...

OBJECTIVES: Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS: From October 2010 to June 2016, we performed first-time MIMVS in 250 consecutive patients (122 male), with median age of 65 years (54-73 years, 25-75 percentile)...

OBJECTIVES: We assessed vortex patterns and energy loss in left ventricular flow in patients who underwent mitral valve repair or replacement with bioprosthetic valves. METHODS: Vector flow mapping was performed before and after the procedure in 15 and 17 patients who underwent repair and replacement, respectively. The preprocedure mitral-septal angle was measured in all patients. Relationships between vortex patterns or energy loss change (ELC) and annuloplasty ring or bioprosthetic valve sizes or the effect of mitral leaflet resection in the repair group were statistically analysed...

OBJECTIVES: Severe cases of infective endocarditis (IE) of the aortic valve can cause aortic root destruction and affect the surrounding structures, including the aortic-mitral continuity, the anterior mitral valve leaflet and the roof of the left atrium. Reconstruction after resection of all infected tissue remains challenging. We describe our surgical approach and the mid-term results. METHODS: Between January 2004 and December 2015, 35 patients underwent surgery for extensive IE of the aortic valve with destruction of the aortic root, the aortic-mitral continuity and the mitral valve...

OBJECTIVES: Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. METHODS: During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included...

Background: Frailty confers risk for surgical morbidity and mortality. Whether patient-reported measures of health, well-being, or quality of life respond differently to surgery in non-frail and frail individuals is unknown. Methods: Older adults with severe aortic stenosis presenting for surgery were assessed for frailty using Cardiovascular Health Study Criteria. Patient-reported measures of functional capacity (Duke Activity Status Index [DASI]), physical and mental health (Medical Outcomes Study Short Form-Physical and Mental Component Scales [SF-12 PCS and SF-12 MCS, respectively]), well-being (linear analogue self-assessment [LASA]), and quality of life (LASA) were administered before and 3 months after surgery...

OBJECTIVES: Atrial fibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and it is often poorly tolerated because of loss of atrial contraction and reduced filling time with rapid ventricular rates. Restoring sinus rhythm is of great clinical benefit to HCM patients. Very few data exist regarding surgical ablation of concomitant AF in this setting. The aim of this study was to evaluate the mid-term outcome of surgical AF ablation in patients who underwent cardiac surgery due to HCM...

Redo aortic valve replacement (AVR) performed simultaneously with left ventricular assist device (LVAD) implantation carries potential for increased mortality rates. Although transcatheter AVR has been used for patients with previous LVAD placement, no literature reports concomitant valve-in-valve transcatheter AVR and LVAD implantation. Our patient had severe aortic prosthetic valve deterioration and advanced heart failure. Given the risks associated with reoperative aortic valve surgery, we chose transcatheter AVR at the time of LVAD implantation...
