Background: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. Methods: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014). A two-patch repair was used in all patients to correct the CAVC defect. Tetralogy of Fallot repair included transannular patch in 11 (65%) patients and valve-sparing in 6 (35%) patients. Results: The average age at surgery was 72 ± 122 weeks, 40% were male, and 80% had trisomy 21. Mean echo follow-up was 3.0 ± 3.0 years. There were no in-hospital or late mortalities. The rate of reoperation was 20%. At the latest follow-up, moderate left atrioventricular valve regurgitation was present in three (15%) patients and mild stenosis present in seven (35%) patients. One (5%) patient had moderate right ventricular outflow tract (RVOT) obstruction. The valve-sparing population was smaller at the time of surgery than the non-valve-sparing cohort (body surface area: 0.28 ± 0.04 vs 0.42 ± 0.11, P = .002) and less likely to have had a previous shunt (0% vs 64%, P = .01). Among the valve-sparing patients (six), at the latest follow-up, moderate pulmonary insufficiency was present in two (33%) patients. Conclusion: Repair of CAVC concomitant with TOF can be performed with low mortality and acceptable perioperative morbidity. Management of the RVOT remains a challenge for the long term.

Abstract Background: Tetralogy of Fallot (TOF) is one of the most common cyanotic congenital heart diseases. Pulmonary regurgitation is the most common and severe comorbidity after transannular patch (TAP) repair of TOF patients. It has not been confirmed whether a TAP repair with monocusp valve reconstruction would benefit TOF patients in perioperative period compared to those without monocusp valve reconstruction. The purpose of the study is to review and analyze all clinical studies that have compared perioperative outcomes of TOF patients undergoing TAP repair with or without monocusp valve reconstruction and conduct a preferable surgery.Methods: Eligible studies were identified by searching the electronic databases. The primary outcome was perioperative mortality. Secondary outcomes included cardiopulmonary bypass time, aortic cross-clamp time, ventilation duration, ICU length of stay, hospital length of stay, and perioperative right ventricular outflow tract (RVOT) pressure gradient. The meta-analysis and forest plots were drawn using Review Manager 5.3. Statistically significant was considered when p-value ≤ 0.05. Results: Eight studies were included which consisted of 7 retrospective cohort study and 1 randomized controlled trial. The 8 studies formed a pool of 526 TOF patients in total, in which are 300 undergoing TAP repair with monocusp valve reconstruction (monocusp group) compared to 226 undergoing TAP repair without monocusp valve reconstruction (non-monocusp group). It demonstrated significant differences between two groups in perioperative cardiopulmonary bypass time (21.86, 95% CI 16.51-27.21), perioperative aortic cross-clamp time (11.20, 95% CI 1.06 - 21.34), mean length of ICU stay (-1.55, 95% CI -3.90 - -0.81), and the degree of perioperative PR (OR=0.02, 95% CI 0.00 - 0.15).Conclusion: Transannular patch repair with monocusp valve reconstruction seems to have significant advantages on some perioperative outcomes of TOF patients. Large, multicenter, randomized, prospective studies focusing on differences between TAP repair with and without monocusp valve reconstruction are needed.

We present a surgical case of native pulmonary valve (PV) restoration in a 16-year-old boy with a previous history of transannular patch repair of tetralogy of Fallot in infancy. The PV was restored by approximation of split anterior commissure in the presence of developed and pliable leaflets well preserved after initial surgery. Postoperative echocardiogram showed a competent valve with peak velocity of 2.8 m/s. At six-week follow-up, the patient remained well, and echocardiogram demonstrated a competent PV with decreased velocity of 2.1 m/s across it. We encourage a mindful preservation of PV leaflets whenever it is possible at time of initial repair to implement this relatively easy operation to restore PV function later in life.

Tetralogy Of Fallot Repair

Background: Although valve-sparing repair remains ideal for patients with tetralogy of Fallot, the durability of valve-sparing repair and which patients may have been better served with a transannular patch remain unclear. Methods: Retrospective review was performed of tetralogy of Fallot operations at our institution from January 2008 to December 2018. Standard demographic data were collected, including echocardiographic parameters, operative details, and clinical outcomes. Statistical analysis was performed comparing the transannular patch and valve-sparing repair groups. Results: Sixty-seven patients underwent tetralogy of Fallot repair with a median age of 4.5 (3.2-6.0) months and weight of 5.8 (5.2, 6.7) kg. Seventeen (25%) patients underwent transannular patch repair and 50 (75%) patients underwent valve-sparing repair. There was no difference in age or weight between patients who underwent a transannular patch repair and those who underwent a valve-sparing repair. At last follow-up (median 42 months), there was a trend of a higher peak pulmonary valve/right ventricular outflow tract gradient ( P = .06) in the valve-sparing group, but no difference in the pulmonary valve annulus z-scores. Additionally, the pulmonary valve z-scores in the valve-sparing group decreased from −2.3 ± 1.0 on predischarge echocardiogram of to −1.2 ± 1.6 on last follow-up, with the peak gradient on predischarge 23 (0-37) mm Hg remaining stable on last follow-up at 18 (0-29) mm Hg. There was one reoperation: pulmonary valve replacement six years after a transannular patch. Conclusions: Obtaining a postrepair pulmonary valve z-score of −2 yields satisfactory, stable valve-sparing repair with pulmonary valve growth, acceptable gradients, minimal regurgitation, and high freedom from reintervention during follow-up.
