selective management of the left Ventricular Outflow Tract for repair of interrupted aortic arch with Ventricular septal defect management of left Ventricular Outflow Tract obstruction
The Journal of Thoracic and Cardiovascular Surgery, 2006Co-Authors: Takaaki Suzuki, Caren S. Goldberg, Paul N Nathan, Carlen A Gomez, Eric J Devaney, Richard G. Ohye, Toru Ishizaka, Edward L BoveAbstract:Objective Left Ventricular Outflow Tract obstruction remains an early and late complication after repair of interrupted aortic arch and Ventricular septal defect. We reviewed our experience with the selective management of the infundibular septum during primary repair to address left Ventricular Outflow Tract obstruction. Methods From 1991 through 2001, all 27 patients presenting with interrupted aortic arch/Ventricular septal defect and posterior deviation of the infundibular septum were analyzed. Fifteen patients with the smallest subaortic areas underwent myectomy or myotomy of the infundibular septum concomitant with interrupted aortic arch/Ventricular septal defect repair. Results Patients undergoing myectomy-myotomy (Group I) had significantly smaller subaortic diameter indexes (0.83 ± 0.16 cm/m 2 ) when compared with those who had only interrupted aortic arch/Ventricular septal defect repair (group 2: 0.99 ± 0.13 cm/m 2 , P = .012). Two hospital deaths occurred in group 1, and 1 occurred in group 2. No late deaths occurred. No patient in group 2 required reoperation. Six group 1 patients required 9 reoperations for left Ventricular Outflow Tract obstruction. Five patients underwent resection of a new subaortic membrane. Only 1 patient had recurrent muscular left Ventricular Outflow Tract obstruction. Three patients required a second reoperation, primarily related to aortic valve stenosis. Conclusions Interrupted aortic arch/Ventricular septal defect with posterior malalignment of the infundibular septum can be repaired with low mortality in the neonatal period. Tailored to the degree of subaortic narrowing, resection or incision of the infundibular septum at the time of primary repair was very effective in preventing or prolonging the interval to recurrent left Ventricular Outflow Tract obstruction compared with the published data. However, reoperation for left Ventricular Outflow Tract obstruction, often related to the development of a new and discrete subaortic membrane or valvar stenosis, is still required in a subset of patients.

Management of Ruptured Left Ventricular Outflow Tract.
The Annals of thoracic surgery, 2019Co-Authors: Dexi Yan, Alexander A. Brescia, Juan Caceres, Linda Farhat, Bo YangAbstract:Left Ventricular Outflow Tract pseudoaneurysm is a potentially fatal complication after aortic root replacement. Challenges surrounding multiple reoperations on the aortic root include sternal reentry, bleeding, valve positioning, compression of coronary arteries, and navigating concomitant interventions. We present a 27-year-old patient with mechanical valves in the aortic and mitral positions and a left main coronary artery drug-eluting stent for left main compression after being diagnosed with rheumatic heart disease at age 16. She underwent a fourth redo modified Bentall procedure with a homemade mechanical composite graft for the contained rupture of an left Ventricular Outflow Tract pseudoaneurysm.

Post-traumatic left Ventricular Outflow Tract pseudoaneurysm.
The Annals of thoracic surgery, 2014Co-Authors: Fei Chen, Shijie Wei, Lian Xiong, Feng LiuAbstract:Left Ventricular pseudoaneurysm forms when cardiac rupture is contained by adherent or scar tissue. It occurs because of a complication of myocardial infarction, cardiac surgery, and, rarely due to thoracic trauma or infective pericarditis. The locations of a pseudoaneurysm include posterior, lateral, apical, inferior, anterior, and basal, but left Ventricular Outflow Tract is quite rare. We present a case of a left Ventricular Outflow Tract pseudoaneurysm after a blunt chest injury. The patient underwent successful aneurysmorrhaphy.

Identifying the Origins of Idiopathic Ventricular Outflow Tract Tachycardia With 12-Leads Body Surface Electrocardiographic Patterns
Chinese Circulation Journal, 2005Co-Authors: Ma JianAbstract:Objective: This study aimed to predict the origins of idiopathic Ventricular Outflow Tract by analysing 12-lead body surface electrocardiograms (ECG) of idiopathic Ventricular Outflow Tract tachycardias. Methods: ECG records of 54 inpatients with idiopathic Ventricular Outflow Tract tachycardias in Fu Wai Hospital were analysed to summarize the characteristics. Results: Different sites of idiopathic Ventricular Outflow Tract tachycardia origin had totally different ECG characteristics. ①ECG of left Ventricular Outflow Tract endocardial origin showed 100% of right bundle branch block pattern,with 87.5% of S wave in lead V_6.②100% of left sinus of Valsalva(LSV) origins fulfilled the criteria of R wave duration index≥50% and R/S wave amplitude index≥30% determined for leads V_1 and V_2.③Inferior leads QRS wave of right Ventricular Outflow Tract(RVOT) free-wall origin demonstrated characteristic‘notching’ on R wave;S wave amplitude was deep in V_2 leads and late precordial transition was seen for free-wall origin. Conclusion:Twelve lead body-surface ECG characteristics have a high sensitivity to identify sites of the idiopathic Ventricular Outflow Tract tachycardia origin.
