We reviewed 25 patients who underwent a mitral valvuloplasty, from 1984 to 1996, for mitral regurgitation (MR) associated with atrial septal defect (ASD). Mean grade of MR was 2.3 +/- 0.7. The locations of mitral valve lesion were as follows; Postero-medial side of the anterior leaflet (AML) (11 patients: 44%), posteromedial side to center of the AML (7 patients: 28%), whole of the AML (5 patients: 20%), center of the AML (1 patient: 4%), posteromedial side of the posterior leaflet (PML) (1 patient: 4%). In summary, the mitral valve lesion was located in the AML in 96% patients and were seen in the postero-medial side of 96% patients. Mitral valve repair was performed as follows; chordae shortening only (3 patients: 12%), chordae shortening + Kay's annuloplasty (9 patients: 36%), Kay's anuloplasty (10 patients: 40%), using artificial chordae only (1 patient: 4%), using artificial chordae + Kay's annuloplasty (1 patient: 4%), using artificial chordae + ring annuloplasty (1 patient: 4%). In 24 patients, the grade of MR was less than 2/4 in the early postoperative period. In one patient, the grade of 3/4 MR was still remained. Reoperation were required in 2 patients, because of gradual increase of MR, 9 years and 10 years after the initial operation, respectively. In another patient, the grade 3/4 MR recurrently occurred at 6 months after the operation. He has been well maintained medically. In all 4 patients who had more than the grade 3/4 MR postoperatively, the annuloplasty was performed with Kay's method and the cause of MR was poor coaptation around the center of the AML. The mitral valve lesion associated with ASD seemed to be the dislocation of the AML which cause the discrepancy of the coaptation zone between both leaflets, without any prominent prolapse and chordae elongation. We put a particular emphasis on that the mitral valve repair should be performed with the recognition of the etiology of the mitral valve lesion. Especially, if the lesion extends around the center of the AML, sufficient coaptation area of both leaflets at the center of the AML should be obtained by anuloplasty.

Intermittent acute porphyria (IAP) is an inborn metabolic disorder of biosynthesis of haeme, characterized by increased excretion of porphyrin or porphyrin precursor in urine and clinically by gastrointestinal, neuro-psychiatric and cardiovascular manifestations. Significant observations were made on echocardiographic examination of 25 IAP patients in our study. Significant decrease in ejection fraction (48.4 +/- 7.9, control group 63.0 +/- 7.5, P < 0.001) and percentage of fractional shortening (23.5% +/- 6.87%, control group = 36.4 +/- 4.26, P </=.001) was observed in IAP, this shows derangement in left ventricular systolic functions in IAP. The study also shows significant thickening of IVS (1.22 +/- 0.20, control group 0.88 +/- 0.12 cm, P </= 0.001). The most interesting finding was the significantly increased incidence of mitral valve and/or tricuspid valve prolapse in 15 (60%) patients of IAP. Thickening of AML, PML, and calcification of AML were also observed.

Facial aging occurs secondary to gravity-induced tissue ptosis and photoaging. Combined face lifting and carbon dioxide laser resurfacing provides a comprehensive one-stage approach to facial rejuvenation but is condemned by many plastic surgeons due to the nonspecific thermal effects of the laser and risk of skin necrosis. Newer high-energy erbium:YAG lasers allow precise tissue ablation with minimal thermal effect. In this study, various facial rejuvenation techniques were combined with simultaneous erbium:YAG laser resurfacing to assess results and complications. A total of 257 patients from Florida, Melbourne, Australia, and Tel Aviv, Israel, underwent combined erbium:YAG laser resurfacing and surgical facial rejuvenation. Various face-lift methods were used, including endoscopic, deep plane, and subcutaneous. Simultaneous, full-facial laser resurfacing was performed using a variety of erbium:YAG lasers. It was found that combined laser resurfacing and face lifting was successful in greater than 95 percent of patients with minimal morbidity. Two patients (1 percent) (both heavy smokers) developed small areas of skin necrosis that healed with minor pigment changes. Five patients (2 percent) developed synechia that was treated with no residual effect. Two additional patients (1 percent) developed temporary ectropion. There were no other cases of scarring, infection, or cosmetically obvious hypopigmentation. Although larger studies are necessary, it seems that the lack of thermal injury from the erbium:YAG laser makes it possible to safely perform laser resurfacing with surgical facial rejuvenation in nonsmokers. However, the authors caution that familiarity with the nuances of erbium:YAG laser resurfacing be obtained before performing combined laser resurfacing and face lifting.

Effectiveness of percutaneous coronary intervention (PCI) within thrombus containing lesions (ST-segment elevation myocardial infarction setting, degenerated saphenous venous grafts) is limited by the risk of occurrence of distal embolization and no-reflow phenomenon. Several pharmacological agents, as well as mechanical devices (i.e. manual aspiration catheters/mechanical thrombectomy, proximal and distal protection devices) were introduced, in the last years, to reduce the risk of angiographic complications during percutaneous coronary intervention and to improve myocardial reperfusion. Recently, the MGuard stent (Inspire MD, Tel Aviv, Israel), a bare-metal stent covered by micron level mesh, which allows to prevent distal embolization by blocking the atherothrombi prolapse through the stent struts during deployment has been introduced. This article discusses the data concerning safety and efficacy of mesh covered stent implantation in a ST-segment elevation myocardial infarction setting, as well as during percutaneous coronary intervention in saphenous venous grafts.
