Paravalvular leaks (PVLs) often occur after surgical valve replacement. Surgical reoperation has been the gold standard of therapy for PVLs, but it carries a higher operative risk and an increased incidence of re-leaks compared to the initial surgery. In high surgical risk patients with appropriate geometries, transcatheter closure of PVLs could be an alternative to redo-surgery. Here, we repor...

We describe surgical treatment for a patient with chronic thromboembolic pulmonary hypertension who developed acute type A aortic dissection. Acute aortic dissection is a life-threatening disease and must be operated emergently, and chronic thromboembolic pulmonary hypertension can be treated only by pulmonary endarterectomy. We performed a staged procedure consisting of hemiarch replacement wi...

Objective. To review the management and outcomes of women with surgically staged 1 UPSC. Methods. We report on a case series from 2008-2010 from Hamilton Canada. We summarize the data from a literature search on surgically staged 1 UPSC. Results. There is a group women with Stage 1A UPSC with no residual disease at time of surgery who do not require adjuvant therapy. Vault recurrences appear to...

Facial gunshot injuries are unusual and complicated clinical entities. Because of the mechanism of injury, early aggressive primary reconstruction might not be ideal. Initial conservative management followed by staged secondary reconstruction could be performed to obtain satisfactory functional and aesthetic results. Reconstruction of the cranio-maxillo-facial deformities requires a multi-disci...

Penile squamous cell carcinoma (pSCC) is a relatively rare disease in Western world but is a significant health problem in developing countries like India. We report here a case of successful multimodality management of recurrent pSCC with pelvic lymphadenopathy in a 56-year-old male patient with poorly controlled diabetes. The patient presented with ulceroproliferative growth over the residual...

Purpose: Total knee arthroplasty (TKA) is the final treatment option for end-stage osteoarthritis. While it expected to resolve pain, 15-40% of patients have persistent pain 6 months after surgery that not otherwise explained (e.g., infection, joint loosening). majority undergo only one replacement, a substantial fraction has both knees replaced, and these are typically staged (performed sequen...

Computational fluid dynamics has been applied to the design, refinement, and assessment of surgical procedures and medical devices. This tool calculates flow patterns and pressure changes within a virtual model of the cardiovascular system. In the field of paediatric cardiac surgery, computational fluid dynamics is being used to elucidate the optimal approach to staged reconstruction of specifi...

Hypoplastic left heart syndrome (HLHS) is a common congenital heart defect that is universally fatal without surgical intervention. Two distinctly different surgical options, heart transplantation and reconstruction surgery, have been successful in treating infants with HLHS. This article reviews the anatomy and pathophysiology of HLHS. Preoperative care of infants with HLHS is discussed. The c...
