RESUMEN
Surgical repair of asymptomatic congenital left ventricular aneurysm is poorly reported. A 30-yearold man presented with an asymptomatic abnormal electrocardiogram. Computed tomography (CT) and angiography revealed a congenital left ventricular aneurysm, and surgical repair was conducted with endocardial linear infarct exclusion technique (ELIET). His postoperative course was uneventful. Postoperative CT showed an elliptical cardiac shape with no recurrence of aneurysm. ELIET would serve as a surgical procedure for congenital left ventricular aneurysm.

A 15-year-old boy with Noonan syndrome, who had been diagnosed with hypertrophic cardiomyopathy (HCM) at 4 and treated by drugs, was referred to our hospital because of progression of left ventricular outflow tract obstruction (LVOTO). Transthoracic echocardiogram (TTE) revealed left ventricular hypertrophy( LVH), LVOTO( systolic gradient:102 mmHg), and systolic anterior motion of the mitral valve( SAM) with mild mitral regurgitation(MR). We performed septal myectomy by transaortic and transapical approaches. Postoperative TTE revealed significant reduction in left ventricular outflow tract (LVOT) gradient (9 mmHg), resolution of SAM, and reduction in MR grade. The postoperative course was uneventful except for transient atrial tachyarrhythmia. Myectomy for HCM in a patient with Noonan syndrome is rare. This case suggests that myectomy is useful for the patients with Noonan syndrome.

A 70-year-old woman with back pain was diagnosed with adult anomalous origin of the left coronary artery from the pulmonary artery [Bland-White-Garland (BWG) syndrome]. Preoperative transthoracic echocardiography showed diffuse hypokinesia of the left ventricle and mild mitral valve regurgitation. Coronary angiography revealed dilatation of both coronary arteries, but no aneurysms. The left coronary ostium was removed as buttons of the pulmonary arterial wall, and a prosthetic graft (8 mm ePTFE graft) was interposed between the ascending aorta and coronary button. The pulmonary arterial wall was repaired with a bovine pericardium. Postoperative angiography showed good flow of the graft. The antegrade flow provided by this simple technique will allow feasible percutaneous coronary intervention in the future.

OBJECTIVES: This study aimed to evaluate the incidence of patient-prosthesis mismatch (PPM) and degree of left ventricular (LV) mass regression after surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) in patients with small aortic annulus (defined as annular diameter of ≤ 21 mm). METHODS: We retrospectively analyzed echocardiographic findings in total of 277 patients with aortic stenosis and small aortic annulus (63 underwent SAVR and 214 underwent TAVR) between October 2013 and March 2019. PPM was defined as an effective orifice area index (EOAI) ≤ 0.85 cm2/m2. LV mass regression was evaluated as percentage change in LV mass index (LVMI) from baseline to the 1-year follow-up. RESULTS: The median EOAI before discharge was slightly larger in the TAVR group than in the SAVR group (1.09 vs. 1.07 cm2/m2; P = 0.030). However, the incidence of PPM before discharge (9.4 vs. 12.7%; P = 0.438) and at the 1-year follow-up (11.7 vs. 11.1%; P = 0.901) was similar between groups. Mild or greater paravalvular leakage (PVL) after the procedure was more frequent in the TAVR group (11.7 vs. 0%; P = 0.002). Reduction in LVMI was significantly higher in the SAVR group (19.3 vs. 6.4%; P < 0.001). Multivariate analysis demonstrated that reduction in LVMI was positively associated with higher baseline transaortic pressure gradient (P < 0.001) and higher baseline LVMI (P < 0.001) and negatively associated with older age (P < 0.001) and mild or greater PVL (P < 0.001). CONCLUSIONS: SAVR provides better LV mass regression than TAVR with a comparable rate of PPM in patients with small aortic annulus.

We describe a patient with reexpanded pulmonary edema after atrial septal defect closure through a right-sided minithoracotomy. After reexpansion of the right lung after weaning from cardiopulmonary bypass, a large amount of serous slight-hemorrhagic bronchial secretions spilled out from the right bronchus. Positive pressure ventilation and differential ventilation were used. We found no bleeding and decreased secretions 24 hours after the onset of reexpanded pulmonary edema. The patient was extubated 42 hours after the operation. To the best of our knowledge, this is the first case report of the development of reexpansion pulmonary edema during a routine minimally invasive operation for atrial septal defect.

PURPOSE: The short-term outcome of physiologic repair for congenitally corrected transposition of the great arteries (ccTGA) is generally considered favorable; however, the long-term outcome is the greatest problem, especially with regard to right ventricular (RV) function and tricuspid regurgitation (TR). Although tricuspid valve replacement (TVR) appears to be a realistic choice for treating severe TR, determining the timing of TVR may be difficult. METHODS: We carried out a retrospective analysis of the long-term outcomes of physiologic repair for ccTGA focusing on patients with TVR. The study involved 23 patients after physiologic repair 10 or more years prior. There were 9 TVR cases in 5 pediatric patients (before age 18) and 4 adult patients. RESULTS: There were two late deaths; however, there was no case related with cardiac events. Overall survival at 10 and 20 years were 95.5 and 90.2 %, respectively, and 7 of 8 patients after TVR were NYHA class I or II. No patient has presented postoperative complications in the form of bleeding or embolism after TVR with mechanical valve. CONCLUSIONS: An analysis of the results of physiologic repair for ccTGA showed that the long-term outcome was overall favorable. To maintain RV function, early TVR may be a reasonable option, even in the management of patients during childhood.
