Transcatheter Valve Repair for Patients With Mitral Regurgitation: 30-Day Results of the CLASP Study

ObjectivesThe authors report the procedural and 30-day results of the PASCAL Transcatheter Valve Repair System (Edwards Lifesciences, Irvine, California) in patients with mitral regurgitation (MR) enrolled in the multicenter, prospective, single-arm CLASP study.BackgroundSevere MR may lead to symptoms, impaired quality of life, and reduced functional capacity when untreated.MethodsEligible patients had grade 3+ or 4+ MR despite optimal medical therapy and were deemed appropriate for the study by the local heart team. All outcomes were assessed through 30 days post-procedure. Major adverse events (MAEs) were adjudicated by an independent clinical events committee, and echocardiographic images were assessed by a core laboratory. The primary safety endpoint was the rate of MAEs at 30 days.ResultsBetween June 2017 and September 2018, 62 patients with grade 3+ or 4+ MR were enrolled. The mean age was 76.5 years, and 51.6% of patients were in New York Heart Association functional class III or IV, with 56% functional, 36% degenerative, and 8% mixed MR etiology. At 30 days, the MAE rate was 6.5%, with an all-cause mortality rate of 1.6% and no occurrence of stroke; 98% had MR grade ≤2+, with 86% with MR grade ≤1+ (p < 0.0001); and 85% were in New York Heart Association functional class I or II (p < 0.0001). Six-minute walk distance improved by 36 m (p = 0.0018), and Kansas City Cardiomyopathy Questionnaire and EQ-5D scores improved by 17 (p < 0.0001) and 10 (p = 0.0004) points, respectively.ConclusionsThe PASCAL repair system showed feasibility and acceptable safety in the treatment of patients with grade 3+ or 4+ MR. MR severity, irrespective of etiology, was significantly reduced and accompanied by clinically and statistically significant improvements in functional status, exercise capacity, and quality of life.

Changes in indications for upper gastrointestinal tract endoscopy and endoscopic findings during the last fifteen years in south-western Greece

BACKGROUND: During the past years, major advances in the management of upper gastrointestinal diseases have been achieved. The aim of this study was to determine if changes in indications for upper gastrointestinal endoscopy and endoscopic findings have occurred during the last 15 years in our area. METHODS: Indications for upper gastrointestinal tract endoscopy and endoscopy findings of patients who underwent upper endoscopy in years 1990, 1995, 2000, and 2005 in our department were compared. RESULTS: Over the 15-year period, the number of diagnostic endoscopies performed in our department in years 1990, 1995, 2000, and 2005 increased (953, 1245, 2350, and 2528, respectively). Acute upper gastrointestinal bleeding had become less frequent (40%, 42.8%, 19.7%, 14.3%, P<0.001), but dyspepsia (24.4%, 33.6%, 54.3%, 51.3%, P=0.002) and reflux (1.8%, 1.3%, 5.1%, 10.8%, P=0.005) more frequent indications for upper endoscopy. The endoscopic findings of duodenal ulcer (39.1%, 22.5%, 20.5%, 9.3%, P<0.001), gastric ulcer (15.9%, 8.3%, 5.7%, 4.6%, P=0.036) as well as erosive gastroduodenitis (35.6%, 22.2%, 15.3%, 4.7%, P<0.001) decreased, whereas that of reflux esophagitis (3.1%, 10.1%, 12%, 16%, P=0.034) increased. Moreover, the percentage of patients with negative endoscopy or minimal endoscopic findings (eg, nonerosive gastritis) increased (12.8%, 33.7%, 54.1%, 64.4%, P<0.001). CONCLUSIONS: In south-western Greece, dyspepsia and reflux as an indication for upper endoscopy have been increasing, whereas acute upper gastrointestinal bleeding has been decreasing. The finding of peptic ulcers at the upper gastrointestinal tract endoscopy has become significantly less frequent, while the percentage of patients with negative results of endoscopy seems to have been increasing rapidly.     

The Ilizarov method for the treatment of complex tibial fractures and non-unions in a mass casualty setting: the 2005 earthquake in Pakistan

We report our experience in treating victims of the recent earthquake disaster in Pakistan. Our experience was based on two humanitarian missions to Islamabad: one in October 2005, 10 days after the earthquake, and the second in January 2006. The mission consisted of a team of orthopaedic surgeons and a second team of plastic surgeons. The orthopaedic team bought all the equipment for application of Ilizarov external fixators. We treated patients who had already received basic treatment in the region of the disaster and subsequently had been evacuated to Islamabad. During the first visit, we treated 12 injured limbs in 11 patients. Four of these patients were children. All cases consisted of complex multifragmentary fractures associated with severe crush injuries. All fractures involved the tibia, which were treated with Ilizarov external fixators. Nine fractures were type 3b open injuries. Eight were infected requiring debridement of infected bone and acute shortening. During a second visit, we reviewed all patients treated during our first mission. In addition, we treated 13 new patients with complex non-unions. Eight of these patients were deemed to be infected. All patients had previous treatment with monolateral fixators as well as soft tissue coverage procedures, except one patient who had had an IEF applied by another team. All these patients had revision surgery with circular frames. All patients from both groups were allowed to fully weight-bear post-operatively, after a short period of elevation to allow the flaps to take. Overall, all fractures united except one case who eventually had an amputation. Four patients had a corticotomy and lengthening, and three of them had a successful restoration of limb length. The fourth patient was the one with the eventual amputation.     

Usefulness of transthoracic echocardiography in demonstrating coronary blood flow after coronary artery bypass grafting

In this pilot study, we used transthoracic echocardiography to measure coronary sinus blood flow in 15 patients before and after coronary artery bypass grafting. Coronary sinus blood flow before and after revascularization was 274 +/- 95 and 451 +/- 102 ml/min, respectively (p <0.001). This finding is consistent with those previously demonstrated by invasive techniques.
