Acute and short term outcomes of balloon aortic valvuloplasty in patients with significant aortic stenosis – A single center experience
Congenital Heart Disease / Indian Heart Journal 69S (2017) S8–S10
by measuring aortic root, STJ and ascending aorta diameter. All patients were evaluated for aortic stenosis, aortic regurgitation, aneurysm and aortic dissection. Results: This study showed that the common type is type 2 with single raphe 76% followed by type 3 20% and type 0 rare 4%. More than 50% patients are associated with aortopathy. Two patients presented with dissection. Conclusion: We found that type 2 is the most common type of bicuspid aortic valve and more than 50% patients had aortopathy with risk of aortic aneurysm and aortic dissection.

ABS372 Uncommon presentation of an uncommon disorder – A case series of double chambered right ventricle in adults Kaku Singh Bhatia ∗ , Oomen K. George, Anoop George Alex, Lijo Varghese Christian Medical College Vellore, Vellore, India E-mail address: [email protected] (K.S. Bhatia). Background: Double-chambered right ventricle (DCRV) is characterized by anomalous muscle bundles that divide the right ventricle into a high pressure proximal chamber and a low-pressure distal chamber. It usually is associated with other congenital defects. It usually presents during childhood and rarely during adulthood. This series aims to document the clinical and hemodynamic profile and surgical outcomes of 9 adults with DCRV. Methodology: Nine adults (>18 years) diagnosed with DCRV based on both echocardiography and cardiac catheterization were studied retrospectively. Diagnostic information and surgical findings were collected by reviewing records. Follow up period varied from 2 to 7 years (Figs. 1 and 2). Results: The age of the patients (3 females and 6 males) varied from 18 to 48 years. Eight patients were symptomatic at presentation while 1 was incidentally detected due to the presence of
E-mail address: [email protected] (K. Patel). Background: We herewith aimed to study outcomes of balloon aortic valvuloplasty via transarterial route in children having severe aortic stenosis. Methods: A total of 58 patients with severe aortic stenosis from a super-speciality cardiac care centre were undergone balloon aortic valvuloplasty and which was successful in 56 patients. They were followed up for 6 months for assessment of their immediate and short term outcome. Results: Balloon aortic valvuloplasty remains the procedure of choice in patients with congenital aortic stenosis, particularly in paediatric age group. All patients enrolled in our study had bicuspid aortic valve morphology on echocardiography. In our study, there was statistically significant (p < 0.05) decline in transaortic gradients after BAV measured either invasively or by continuous wave Doppler method. The continuous wave Doppler derived maximum transaortic gradient which was decreased by 56.5% and mean transaortic gradient was decreased by 61% after BAV in our study. Immediate and short term outcomes were favourable as there was only 1 case with significant restenosis. 17% patients developed moderate AR and 15% patient had local complications. Conclusion: Balloon aortic valvuloplasty via trans-arterial route in paediatric population with significant aortic stenosis is safe, effective palliation for intermediate and midterm follow up with minimum complications and shown to prolong the need for early surgical intervention with very low rate of short term restenosis.
