Abstract

Right ventricular (RV) volume overload increases morbidity and mortality after tetralogy of Fallot (TOF) repair. Surgical strategies like pulmonary leaflets sparing and tricuspid valve repair at time of primary repair may decrease RV overload. Our objective is to evaluate early and midterm results of pulmonary leaflets sparing with infundibular preservation and tricuspid valve repair in selected TOF patients with moderate pulmonary annular hypoplasia. From 2011 to 2016; 46 patients with TOF and moderate pulmonary annular hypoplasia had surgical repair with sparing of the pulmonary valve leaflets. Concomitant tricuspid valve repair was performed in 33 patients (71.8%). Mean age was 13.1 ± 4.8 months, 68% were males (n = 31) and mean weight was 9.5 ± 2.3 kg. Preoperative McGoon ratio was 1.9 ± 0.4 and pulmonary valve z-score ranges from - 2 to - 3. Preoperative pressure gradient of RVOT was 80.9 ± 7.7 mmHg and 10.9% had minor coronary anomalies (n = 5). All repairs were performed through trans-atrial trans-pulmonary approach. 87% had pulmonary valve commissurotomy (n = 40). Mean cardiopulmonary bypass time was 71 ± 6.3 min and ischemic time 42.4 ± 4.9 min. Hospital mortality occurred in 4.3% (n = 2). Mean RVOT pressure gradient decreased significantly postoperatively (28.8 ± 7.2 mmHg, p-value< .001) and at the last follow up (23.6 ± 1.8 mmHg, p-value< .001). Pulmonary regurgitation progressed by one grade in 2 patients compared to the postoperative grade. 1 patient (2.5%) had late mortality and reintervention was required in 5 patients (12.5%). Pulmonary leaflets sparing, and tricuspid valve repair are safe for TOF repair with no added morbidity or mortality. These procedures could contribute to reducing right ventricular volume overload over time after TOF repair.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 June 2018.
All research outputs
#20,523,725
of 23,092,602 outputs
Outputs from Journal of Cardiothoracic Surgery
#935
of 1,251 outputs
Outputs of similar age
#378,540
of 441,387 outputs
Outputs of similar age from Journal of Cardiothoracic Surgery
#15
of 18 outputs
Altmetric has tracked 23,092,602 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,251 research outputs from this source. They receive a mean Attention Score of 2.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 441,387 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
