  • Research progress of pulmonary hypertension due to left heart disease

    Pulmonary hypertension due to left heart disease (PH-LHD) is the most common in various types of pulmonary hypertension. Although there are many treatments for pulmonary hypertension, it may be harmful when we adopt treatment without detrimental diagnosis and classification of pulmonary hypertension. Therefore, it is very crucial to have accurate diagnosis and classification of pulmonary hypertension before making treatment decisions. However, there are still some difficulties in the classification of pulmonary hypertension in clinical work. It is a great challenge with limited treatment to solve the PH-LHD which often has complicated pathophysiological mechanisms of precapillary and postcapillary pulmonary hypertension. Here, we review the research status of PH-LHD.

  • Progress in Minimally Invasive Surgery for Atrial Fibrillation

    Atrial fibrillation (AF) is difficult to cure for its complex etiology and long disease duration. Heart failure, sudden death and stroke are the main causes for consequent high mortality and morbidity. In recent years, minimally invasive surgery has made rapid progress, not only improved treatment efficiency of traditional Cox Maze procedure but also massively reduced surgical injuries, and has become a preferred treatment strategy for lone AF. Minimally invasive surgery and catheter ablation complement each other, and are likely to open up a new prospect of AF treatment.

  • The progress of complications of transcatheter aortic valve implantation

    Surgical aortic valve replacement is the primary choice for the treatment of aortic valve stenosis. It can significantly improve the quality of life and life expectancy of patients, but some patients have risks such as advanced age and poor general conditions and can not receive open chest surgery. In 2002, a French doctor, Cribier, successfully performed transcatheter aortic valve implantation (TAVI) surgery on a patient with aortic stenosis. At present, the safety and effectiveness of TAVI surgery have been confirmed by many studies. However, its complications are also relatively common. This article summarizes the related reports at home and abroad.

  • Advances in transcatheter aortic valve replacement for pure native aortic regurgitation

    Transcatheter aortic valve replacement (TAVR) has been confirmed to be safety and efficacy for high-risk elderly aortic stenosis, and the clinical effect of TAVR for medium and low-risk aortic stenosis is not worse than that of surgery. The development of surgical techniques and instruments has made cardiologists attempt to broaden the surgical indications. Many elderly and high-risk patients with pure native aortic regurgitation have been treated “off label” with similar techniques, completing artificial valve replacement, restoring valve function and improving the prognosis. However, due to the high requirements of surgical techniques and surgical complications, there is a lack of randomized controlled studies to confirm its safety and effectiveness. Unlike aortic stenosis, native aortic regurgitation presents unique challenges for transcatheter valves. In this article, the authors review current advances in the treatment of aortic valve regurgitation with TAVR.

  • Expert recommendations for standardized perioperative management after transapical transcatheter aortic valve implantation

    The technique of transcatheter aortic valve implantation has become increasingly mature. Although the transapical approach has a certain degree of minimally invasive trauma, it still has the characteristics such as heart beating without cardiopulmonary bypass, and the low technical requirements of catheter guide wire. In particular, the valve path is short and coaxial, which is easy to manipulate, and pure regurgitation and stenosis can be easily operated and are not subject to the limit of peripheral artery stenosis. It is still one of China's main approaches for transcatheter aortic valve replacement. Its perioperative management still has specific features and differs from the femoral artery approach. In addition, there is little relevant literature abroad. Therefore, domestic experts in this field were organized to discuss the development of perioperative management specifications to provide reference and techniques support for developing this field in China and further improve the quality of clinical operation and perioperative management. It will provide more safe and more effective medical services to these patients.

  • Research progress of antegrade cerebral perfusion and retrograde cerebral perfusion in aortic arch surgery

    Antegrade cerebral perfusion (ACP) and retrograde cerebral perfusion (RCP) are the two major types of brain protection during aortic arch surgery. Which one is better has still been debated. By summarizing and analyzing the research progress of the comparative research of antegrade cerebral perfusion and retrograde cerebral perfusion in aortic arch surgery, we have found that there was no significant difference between ACP and RCP in terms of temporary nerve dysfunction (TND), permanent nerve dysfunction (PND), stroke, early mortality, morbidity, long-time survival, and a composite outcome of hospital death, bleeding, prolonged ventilation, need for dialysis, infection and stroke. But RCP resulted in a high incidence of prolonged mean ICU-stay and hospital-stay, longer mean extubation time as well as higher cost. And the surgeon is given more time to reconstruct the vessels of the arch since mean operative time is longer in the ACP. So we think that antegrade cerebral perfusion might be preferred as the brain protection method for complicated aortic arch procedures. If a surgeon confirms that the surgery is not very sophisticated and can be completed in a short time, it is better to choose RCP because of no catheter or cannula in the surgical field to impede the surgeon. The article aims at providing a reference to cardiac surgeries when choosing cerebral protection strategy in aortic arch surgery.

  • Early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation

    ObjectiveTo evaluate the early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation.MethodsThe clinical data of 31 patients with atrial fibrillation who underwent total thoracoscopic Box Lesion radiofrequency ablation between November 2011 and March 2018 at the Department of Cardiac Surgery in our hospital were retrospectively analyzed, including 23 males and 8 females at an average age of 66.17±8.32 years. All patients did not have concomitant severe organic heart disease which required surgical intervention.ResultsThere were 20 patients with paroxysmal atrial fibrillation, 8 with persistent atrial fibrillation, and 3 with long-standing persistent atrial fibrillation. Twenty-nine patients got the 3-year follow-up, and 2 patients were lost to the follow-up 6 months after the surgery. The procedure was successfully performed in all patients, with an average operation time of 113.00±26.00 min. There was no perioperative death or related complication. All patients were restored to sinus rhythm immediately after surgery. Five patients got atrial fibrillation during postoperative hospitalization, which reverted to sinus rhythm after electrical cardioversion. The rate of sinus rhythm maintenance was 62.9%, 55.9% and 52.4% in postoperative 1, 2 and 3 years, respectively. No patient died during the period, and no procedure-related complication was observed.ConclusionTotal thoracoscopic Box Lesion radiofrequency ablation effectively shortens operation time, and reduces surgical trauma and procedure-related complications, meanwhile, ensures the surgical outcomes.
