The first well-documented case of Holmes heart associated with an atretic left atrioventricular orifice is reported. The Holmes heart may be considered as a single ventricle in which the main chamber has the morphologic characteristics of a left ventricle, the infundibular chamber is not inverted, and the great arteries are normally arranged. The importance of this report is greater than its si...

We present the concept of natural orifice surgery and of scarless operations, with their access routes, their multidisciplinary character, and challenges to their development. We point out the intra- and postoperative advantages. We emphasize the use of the vaginal route and posterior colpotomy in the application of natural orifice surgery in vaginal hysterectomies and surgical access to adnexa...

A young Hindu lady of about 23 years ot age consulted me for the flow of a limpid fluid from behind the left ear whenever she took food. This complaint had lasted for some 13 years. On examination I found a tiny fistula, with its orifice about half an inch behind the left ear. On enlarging and deepening the orifice nothing abnormal could be detected, but the wound did not heal under antiseptic ...

Abstract: A detailed numerical study of turbulent flow through a micro-orifice is presented in this work. The flow becomes turbulent due to the orifice at the considered Reynolds numbers (∼104). The obtained flow rates are in good agreement with the experimental measurements. The discharge coefficient and the pressure loss are presented for two input pressures. The laminar stress and the genera...

Up to now, a few formulas have been suggested by scholars for the amount of discharge from openings, however, the effect of opening's geometry on the amount of discharge has not addressed thoroughly. In this study, to assess the effect of rectangular openings’ aspect ratio on the discharge amount, experimental and numerical investigations have been conducted on the discharge amount from rectang...

We treated a patient with dilated cardiomyopathy (DCM) and sustained ventricular tachycardia by an implantable cardioverter defibrillator (ICD). He then suffered from inappropriate ICD shocks triggered by paroxysmal atrial fibrillation (AF). We successfully performed pulmonary vein orifice isolation to eliminate paroxysmal AF. The pulmonary vein orifice isolation was a simple and useful procedu...

In a patient with endocarditis and significant aortic insufficiency, two-dimensional echocardiography revealed an abnormal mitral valve configuration with division of the valve into two separate orifices. At autopsy, a double orifice mitral valve with two sets of valve leaflets was observed. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is a...

For patients refusing surgical treatment for deep early gastric cancer, hybrid natural orifice transluminal endoscopic surgery with sentinel lymph node navigation is a potential treatment option, particularly when the anatomic location of the cancer has low probability of lymph node metastasis. We report a case of deep early gastric cancer of the fundus beyond the endoscopic submucosal dissecti...
