The causes of left ventricular outflow tract obstruction (LVOTO) include congenital left ventricular outflow tract stenosis, hypertrophic obstructive cardiomyopathy, mitral accessory valve^[1]After mitral valvuloplasty, etc. However, reports of LVOTO in tricuspid valve deformation are rare, Hirata et al.^[2]A case of tricuspid valve deformation with LVOTO before operation was reported, which was mainly caused by atrialized right ventricle resulting in deformation of ventricular septal base; Waterhouse et al.^[3]A patient with tricuspid downward deformity with dynamic LVOTO due to massive tricuspid regurgitation has also been reported. We summarize the treatment experience of 8 cases of LVOTO in the correction of tricuspid valve deformity, which are reported below.

The incidence of left ventricular tumors is low, accounting for only 2.5% ~5.0% of all cardiac tumors^[1], mostly case reports. The experience of surgical treatment of 17 cases of benign left ventricular tumors in our center is summarized and reported as follows.

Male, 77 years old. Since September 2016, there was no obvious trigger for dull pain in the lower back, which was relieved after symptomatic treatment. In March 2017, I came to our hospital for treatment with aggravated lower back pain. Thoracic and abdominal enhanced CT showed angiomatous dilatation of the aortic arch, thoracic and abdominal aorta to iliac with intramural hematoma formation, and the diagnosis of intramural hematoma of aortic dissection (Stanford type B) was proposed. The patient had a history of hypertension for 40 years, with the highest blood pressure of 169/90 mmHg (1 mmHg =0.133 kPa), controlled by oral benazepril tablets, and systolic blood pressure of 120-150 mmHg; 3-year history of diabetes, insulin aspart 30 injection (NovoRui 30) was injected subcutaneously 19U early and 11U late; He has a history of autoimmune pancreatitis for 6 years. He was treated with oral prednisone and stopped it voluntarily in the past 1 year. Smoking history for 40 years, quit smoking for 6 years.
