To investigate outcome after septal myectomy and to evaluate long-term hemodynamics with exercise echocardiography.
This study included 40 consecutive patients operated with septal myectomy for hypertrophic obstructive cardiomyopathy from January 1998 to August 2017 at Skane University Hospital, Lund, Sweden. Perioperative clinical data and echocardiography measurements were reviewed retrospectively. Patients (
= 36) who were alive and living in Sweden were invited for exercise echocardiography to evaluate exercise capacity and hemodynamics, of whom 19 patients performed exercise echocardiography.
Overall survival was 100% at 1 year and 96% at 5 years following surgery. Preoperative median resting peak LVOT (left ventricular outflow tract) gradient was 80 mm Hg. Septum thickness was reduced from 22 ± 4 mm preoperatively to 16 ± 3 mm postoperatively (
< 0.001). During exercise echocardiography, the peak LVOT gradient was 8 mm Hg at rest, and increased to 13 mm Hg during exercise echocardiography (
= 0.002). None of the patients had dynamic LVOT obstruction during exercise echocardiography, and there was no clinically significant systolic anterior motion or severe mitral insufficiency during exercise.
Long-term survival following septal myectomy is very good. At long-term follow-up, LVOT gradients were low and exercise echocardiography demonstrated good hemodynamics.

In patients eligible for coronary artery bypass grafting, no data assess the importance of the Heart Team in programming the best surgical strategy for patients with diffuse coronary artery disease (CAD). This study aims to determine the contribution of the Heart Team in predicting the feasibility of coronary artery bypass graft and angiographic surgical success in these patients based on visual angiographic analysis.
Patients with diffuse and severe CAD undergoing incomplete coronary artery bypass graft surgery were prospectively included. One-year postoperative coronary angiograms were obtained to evaluate graft occlusion. Two clinical cardiologists, two cardiovascular surgeons, and one interventional cardiologist retrospectively analyzed preoperative angiograms. A subjective scale was applied at a single moment to quantify the chance of successful coronary artery bypass grafting for each coronary territory with anatomical indication for revascularization. Based on individual scores, the Heart Team's and the specialists' scores were calculated and compared.
The examiners evaluated 154 coronary territories, of which 85 (55.2%) were protected. The Heart Team's accuracy for predicting the angiographic success of the surgery was 74.9%, almost equal to that of the surgeons alone (73.2%). Only the interventional cardiologist predicted left anterior descending territory grafting success. The Heart Team had good specificity and reasonable sensitivity, and the surgeons had high sensitivity and low specificity in predicting angiographic success.
The multispecialty Heart Team achieved good accuracy in predicting the angiographic coronary artery bypass graft success in patients with diffuse CAD, with a high specificity and reasonable sensitivity.

To more minimize the minimally invasive valve surgeries, percutaneous vascular access and closure has been used for the establishment of extracorporeal circulation. This study investigates early clinical outcomes of patients who received MANTA for femoral artery closure as first experiences in minimally invasive valve surgery.
Between January 2019 and July 2019, 103 consecutive patients (mean age 58 ± 11 years) underwent video-assisted minimally invasive valve surgery through right anterior minithoracotomy at two cardiac surgery referral centers in Germany. Percutaneous cannulation for cardiopulmonary bypass and femoral artery closure with MANTA were performed in all patients 18-F and 14-F MANTA were used in 88 (85.4%) and 15 (14.6%) patient, respectively. Mitral, aortic, tricuspid, and double valve surgeries were performed in 51 (49.5%), 39 (37.9%), 7 (6.8%), and 6 (5.8%), patients, respectively. Clinical data were prospectively entered into our institutional database.
Cardiopulmonary bypass time and cross-clamping time were 69 ± 23 and 38 ± 14 minutes, respectively. Except for two patients with late pseudoaneurysm on 15th and 23th postoperative day, neither major nor minor vascular complications nor vascular closure device failure according to the Valve Academic Research Consortium-2 definition criteria was observed. Additionally, no wound healing disorders or conversion to surgical closure was observed.
MANTA as percutaneous femoral artery closure after decannulation of cardiopulmonary bypass is a safe, feasible, and effective approach and yields excellent early outcomes. Larger size studies are needed to evaluate more the efficacy and safety of MANTA.

Cochlear implant qualifying criteria for adult patients with public insurance policies are stricter than the labeled manufacturer criteria. Blebbistatin research buy It remains unclear whether insurance payer status affects expedient access to implants for adult patients who could derive benefit from the devices.
This study examined whether insurance payer status affected access to cochlear implant services and longitudinal speech-perception outcomes in adult cochlear implant recipients.
Retrospective cross-sectional study.
Sixty-eight data points were queried from the Health Insurance Portability and Accountability Act-Secure, Encrypted, Research Management and Evaluation Solution database which consists of 12,388 de-identified data points from adult and pediatric cochlear implant recipients.
Linear mixed-effects models were used to determine whether insurance payer status affected expedient access to cochlear implants and whether payer status predicted longitudinal postoperative speech-perception scores in quiet and noise.
