Results of AV valve surgery in patients with Fontan circulation were evaluated over a 23 year period. 54 (9.3%) of patients requird AV valve surgery, mostly prior to the Fontan operation. 90% of patients were free from death or transplantation at 5 years; this fell to 81% at 10 years. Nearly 45% required AV valve reoperation. The rate of persistent AV valve regurgitation was 26% at 5 years and 33% at 10 years.

Patients with LV dysfunction who underwent complete surgical revascularization were evaluated with angiograms, echo, and MR (evaluating late vascular enhancement with contrast). About 70% of dysfunctional segments segments demonstrated improved wall motion after revascularization, and this was unrelated to the degree of late vascular enhancement evident preoperatively.

Results of moderate hypothermic arrest and antegrade cerebral perfusion (MHCA group) were compared with deep hypothermic arrest and retrograde cerebral perfusion (DHCA) for management of hemiarch reconstruction using single institution data. The MHCA group was older and more often affected by atherosclerotic aneurysm. MHCA was associated with shorter CPB times and aortic crossclamp times and with less need for transfusion. Acute outcomes were similar between the groups.

You have heard of 4 port, 3 port, 2 port and now uniportal VATS lobectomy. You may have tried Robotic lobectomy. You may also have heard of subxiphoid only or TEMLA only lobectomy.
Well here is another approach for your collection ! However for me it has the advantages of minimal learning curve for VATS lobectomists, and smaller incisions than uniportal vats in the intercostal spaces, and of course a new gadget or two to try which has to be a good thing !!
Anyway it is not for me to say what I like about it, it is for you to tell me what you think.

Over a time of 25 years, 51 patients underwent the Ross and 14 the Ross-Konno procedure. Rates of freedom from right ventricular outflow tract intervention was 59% and from autograft intervention was 81% at 15 years. About half of the patients had mild-to-moderate aortic root dilatation.

Fifty-two children with thymic hyperplasia subsequent to chemotherapy for lymphoma were observed for a median of 33 months. Mediastinal masses were clear-shaped in 42 and diffuse in 10 children. Uptake of contrast agent was observed in all masses. Long-term regression of the hyperplasia was found in 42 and unchanged appearance in 10 children.

Within 34 years, 129 patients with a median age of 2 years underwent PCTR. Eighteen revision operations were necessary. Decannulation and satisfactory respiratory and swallowing function were achieved in over 80%, a good voice, however, in only about two third.

In this manuscript the authors describe a systematic review of 71 cases of transcatheter heart valve embolization. In 72% of the patients, the prosthesis used was a balloon expandable one. In most cases valve embolization occurred soon after implantation and it happened in the aortic direction. Interestingly, when the access was transapical, the prosthesis more often embolized into the left ventricle. Early embolization was most commonly secondary to device malposition and pacing error. Late embolization was reportedly due to chest compression during cardiopulmonary resuscitation, asymmetric calcification, and low prosthesis implantation. Suggestions are made on how to prevent this complication and how to proceed when it happens.

The authors reviewed patients with small resected stage I lung adenocarcinoma to determine the frequency of tumor cells spreading through airway spaces (STAS) and their relationship to recurrent cancer. Nearly 40% of patients had tumor cells in the airways beyond the edge of the main tumor. In patients undergoing parenchymal-sparing operations, the recurrence rate was much higher in patients with tumor STAS (43% vs 11%). This relationship was not identified in patients undergoing lobectomy. Tumor STAS should be recognized as a pattern of invasive spread among patients with lung adenocarcinoma.
